Description
The invention relates to by aqueous dispersion and add to the sized paper that a kind of slush pulp and drying obtain a kind of cationic polymer.
The aqueous dispersion of cationic polymer of the present invention is used to form a kind of softness films with antistatic or semiconductor waterproof.This filming can be by with this aqueous dispersion dipping or apply a matrix, for example paper and plastic sheeting and dry and form.
In a kind of important use, cationic polymeric dispersion of the present invention is coated to a kind of electric imaging record series of strata, wherein on electric imaging recording materials, form latent image by electric signal, described electric imaging recording materials include the carrier of an electric insulation, one conductive layer and a recording layer are arranged on it in order, and set has a kind of charged toner powder to obtain visible image above it.In this application, aqueous polymer dispersion of the present invention can be used from conductive layer so that the electric imaging recording materials with good film characteristics and writing function to be provided individually or with a kind of metal-oxide semiconductor (MOS) one.
In another kind was used, cationic polymeric dispersion of the present invention was useful as the additive in the papermaking.In more detail, in the forming process of sheet material, aqueous dispersion of the present invention can add under neutrality or the alkali condition with colloidality and wet strength on improving, thereby is applicable to corrugated board of producing paper container, waterproof enhancing or the like.In addition, cationic polymeric dispersion of the present invention is hopeful to utilize it to reduce the effect of surface resistivity or specific insulation and be applied to wrapping paper of dustproof paper, IC (integrated circuit) parts or the like; Utilize its heat-sealing ability to be applied on the heat seal paper or the like; And the characteristic of utilizing its set dyestuff or pigment is applied on the painted matrix that laminated decorative panel and coating paper use.
Provide several aqueous polymer dispersions as conductive agent or antistatic additive, carried out drying then with these aqueous dispersion dippings or coating insulating body (for example paper and plastic sheeting).In these aqueous dispersions, a kind of aqueous dispersion of known cationic styrene polymer becomes quaternary salt to obtain by making chloromethylated polystyrene with a kind of reactive tertiary amine, and this has description in as Japanese patent laid-open publication gazette 7871/73 and 34150/74.But,,, surface conductivity is caused harmful effect in the preservation process so matrix is easy to curl or film be easy to break owing to applying cationic styrene polymer and the dry shortage flexibility of filming that forms on the paper or on the plastic sheeting.
Be used at cationic polymer under the situation of conductive layer of electric imaging recording materials, described polymer mixes with a kind of metal-oxide semiconductor (MOS) etc., so that improve electric conductivity and reduce sheet resistance to dependence on temperature, this has introduction (term " OPI " refers to " not examining disclosed Japanese patent application " here) in as Japanese patent application (OPI) 9524/80 and 331/80.In this respect, when independent use cationic styrene polymer, it is not enough to the absorbability of inorganic filler.Consider that from the stability of record video under lower-temperature atmosphere the absorbability of metal-oxide semiconductor (MOS) is had special importance.
On the other hand, the aqueous dispersion of known cationic polymer by ethylene copolymer preparation includes and a kind ofly reacts the aqueous dispersion that obtains by the copolymer and a kind of acid that make ethylene/acrylic acid aminoalkyl ester compounds in water, and this introduces in Japanese patent application (OPI) 16542/72.This aqueous dispersion is good for the absorbability of inorganic filler such as metal-oxide semiconductor (MOS) (for example zinc oxide, tin oxide, titanium oxide etc.), after it is coated on the last also drying of matrix (as paper and plastic sheeting), provide one deck semiconductor not only soft but also water-fast or solvent to film.Although formed the filming of aqueous dispersion by the copolymer of ethylene/acrylic acid aminoalkyl ester compounds has these advantages, compare with filming of cationic styrene polymer, the former has higher surface resistivity.Aqueous dispersion on this conductive layer that is coated to the electrographic recording material does not reach enough writing functions, thereby uses in practice as yet.
Form the field at sheet material, disclosed series of strata are noticeable in the Japanese patent application (OPI) 98304/83 and 180697/83.According to these series of strata, in water, react and generate quaternary salt and then make it and show fontanel and carry out the aqueous dispersion that addition reaction obtains by in moisture pulp material, adding a kind of copolymer by making ethylene/acrylic acid aminoalkyl ester compounds and various organic or inorganic acid, can improve upward colloidality and wet strength simultaneously for alcohol.
The inventor studies the practical application of above-mentioned technology.Yet, the aqueous dispersion that makes owing to the copolymer from ethylene/acrylic acid aminoalkyl ester compounds should add so that bring about the desired effect with sizable amount, so, compare with the general series of strata that adhesive and wet strength agent use, from the viewpoint of economy, the result who obtains is not gratifying for practical application.
Therefore, required to solve the incident variety of issue of aqueous dispersion that makes with traditional copolymer from ethylene/acrylic acid aminoalkyl ester compounds, the electric conductivity of filming that promptly obtains is not enough, and the function that gives colloidality and wet strength in sheet material forms simultaneously is not enough.
In sum, an object of the present invention is to provide a kind of aqueous dispersion of the cationic polymer that makes from ethylene copolymer, from function and economic viewpoint, it has actual benefit as the conductive layer of electric imaging recording materials or the additive of paper grade (stock).
According to the extensive studies result, found from the cationic polymeric dispersion that the novel copolymer of ethene and aminoalkyl acrylamide comonomer makes compare with traditional cationic polymeric dispersion demonstrate form conducting coating characteristic be improved significantly, and make colloidality and wet strength generation significantly improve effect simultaneously.
In first embodiment of the present invention, a kind of aqueous dispersion of cationic polymer is provided, it is to react in water to form quaternary salt by the ethylene copolymer of at least a aminoalkyl acrylamide comonomer that makes a kind of ethene that contains 40～80% (weight) and 20-60% (weight) and hydrochloric acid, by addition reaction the quaternary salt that obtains and the reaction of a kind of epihalohydrin compound are obtained then, described comonomer is represented with following formula (I) and is had a melt index (MI) of/10 minutes of 10～1000 grams (according to the method mensuration of JISK-6760).Formula (I) is expressed as
R in the formula
1Represent a hydrogen atom or a methyl; R
2And R
3Each represents a hydrogen atom or the alkyl with 1～4 carbon atom; N is an integer of 2～4.
In second embodiment of the present invention, improved a kind of by in above-mentioned cationic aqueous polymer dispersion, adding a kind of alcohol amine compound, heat-treating the aqueous dispersion of the cationic polymer that obtains then.
At first, according to aqueous dispersion of the present invention, it is characterized in that only having excellent absorption ability, and be the flexibility of filming that forms thus, eliminated hidden danger such as problems such as curling of film rhegma or matrix to inorganic filler such as metal-oxide semiconductor (MOS); And filming of forming thus has gratifying resistance to water and solvent resistance, so, compare in practicality more reliable with the aqueous dispersion of commercially available cationic styrene polymer.Moreover, the aqueous dispersion of first embodiment provides superior filming, and its surface resistivity is far below the surface resistivity of filming that traditional cationic polymeric dispersion obtained that makes by the copolymer from ethylene/acrylic acid aminoalkyl ester compounds.
Secondly,, it is characterized in that comparing the obvious behavior of going up colloidality and wet strength simultaneously that improved, so just can reach desirable efficacy levels in the practical application with the additive of decrement with the aqueous dispersion of aforementioned conventional according to aqueous dispersion of the present invention.
The preparation that can be used as the ethylene copolymer of raw material can be passed through radical polymerization 40～80% (weight) under High Temperature High Pressure, preferably ethene and 20～60% (weight), the preferably represented aminoalkyl acrylamide comonomer realization of at least a formula (I) of 25～50% (weight) of 50～75% (weight).
If the content of the chain link of the aminoalkyl acrylamide comonomer in the ethylene copolymer is lower than 20% (weight), the content that is to say the ethene chain link is higher than 80% (weight), then quaternary salt and table fontanel may have very poor hydrophily for the product that the addition reaction between the alcoholic compound obtains, and can not provide to contain all fine grain stable aqueous dispersion.On the other hand, if the content of ethene chain link is lower than 40% (weight), that is to say that the content of aminoalkyl acrylamide comonomer chain link surpasses 60% (weight), the aqueous dispersion that then obtains only forms and is not enough to water-fast and low excessively the filming of film-strength.When such film during as the conductive layer of electric imaging recording materials, writing with pencil or ball pen to be impossible, that is to say when such aqueous dispersion is used as the additive of paper, for last colloidality to improve effect not enough.
The viewpoint of the physical property of filming, the particularly film strength that forms from the viscosity of aqueous dispersion with by this aqueous dispersion is used for ethylene copolymer of the present invention and should has 10～1000 grams/10 minutes.Preferably 30～500 restrain/10 minutes melt index (MI) (measuring) according to JISK6760.
According to above-mentioned for example Japanese patent laid-open publication gazette 22523/67 and 5194/78 method, above-mentioned ethylene copolymer can be by the preparation of high-pressure free radical polymerisation.More particularly, the aminoalkyl acrylamide compound of ethene and formula (I) is fed a vessel type reactor of being furnished with agitator or barrel reactor continuously with a kind of free radical catalyst such as oxygen, organic peroxide, azo-compound etc. so that under the temperature of the pressure of 500～3000kg/cm and 100～300 ℃, carry out polymerization.Can use various types of chain-transferring agents, for example ethane, propane, propylene etc. are to adjust the molecular weight of polymer.
The object lesson that can be used for the aminoalkyl acrylamide comonomer of recommendation of the present invention has dimethylaminoethyl acrylamide, dimethyl aminopropyl acrylamide, dimethylamino butyl acrylamide, diethyl aminoethyl acrylamide, diethyl amino propyl group acrylamide, diethyl amino butyl acrylamide, di aminoethyl acrylamide, di aminopropyl acrylamide, N-(1, the corresponding methacrylamide derivatives of acrylamide or the like 1-dimethyl-3-dimethyl aminopropyl), and these acrylamide derivatives.These aminoalkyl acrylamide comonomers both can use separately.Also can two or more combine use.
In the comonomer of enumerating in the above, what recommended most is dimethyl aminopropyl acrylamide, dimethyl aminopropyl Methacrylamide, dimethylaminoethyl acrylamide and dimethylaminoethyl Methacrylamide.
In order to improve the pliability of filming that forms by this aqueous dispersion or to reduce heat-sealing temperature, ethylene copolymer also can include one or more comonomers except that ethene and aminoalkyl acrylamide compound, for example methyl acrylate, methyl methacrylate, ethyl acrylate, n-butyl acrylate, vinylacetate, propionate, dimethylaminoethyl acrylate methyl base aminoethyl ester, acrylic acid dimethylaminoethyl ester or the like, its ratio can be up to 20% (weight).
The amount of hydrochloric acid that is used for the ethylene copolymer quaternization is between the ethylene copolymer of per 100 parts (moles) amino 50～200 parts, preferably 80～150 parts (mole).If the consumption of hydrochloric acid is lower than 50 parts, the quaternary salt that then obtains often has very poor hydrophily, and the addition compound product that obtains with epihalohydrin compound reaction subsequently can not provide the stable and low viscous all fine grain aqueous dispersion that contains.On the other hand, if the consumption of hydrochloric acid surpasses 200 parts, the aqueous dispersion that obtains thus forms films that often resistance to water and film strength are not enough.
In general; be pill or pulverous ethylene copolymer and hydrochloric acid and under 60～100 ℃ and atmospheric pressure, mixture stirred 30～120 minutes by in the water of 100 weight portions, adding 5～35 weight portions, can fully finish the quaternization of hydrochloric acid and ethylene copolymer and react.In some cases, ethylene copolymer still keeps its shape in the quaternization course of reaction, just with the aqueous hydrochloric acid solution swelling.Because the addition reaction that reaction system contains thing by follow-up and epihalohydrinization becomes and a kind ofly contains all fine grain aqueous dispersion, so this carrier can not have problems.
Then, hydrochloric acid quaternary salt and a kind of table fontanel of the ethylene copolymer that obtains thus carried out addition reaction for alcoholic compound, thereby form a kind of even and stable aqueous dispersion.
The epihalohydrin that participates in reaction comprises chloropropylene oxide, epibromohydrin or the like, and particularly best with chloropropylene oxide.According to the amino meter of per 100 parts (moles) contained in the ethylene copolymer, the consumption of epihalohydrin is 50～200 parts (moles), preferably 80～150 parts (mole).When the consumption of epihalohydrin compound is lower than 50 parts, can not obtain the stable and low viscous all fine grain aqueous dispersion that contains; If its consumption surpasses 200 parts, profit to aqueous dispersion only form can not be fully water-fast and low the filming of film strength, caused the problem in the actual use.
With the addition reaction of epihalohydrin compound generally can 20～100 ℃, be preferably in 40～90 ℃ and stir under carried out 30～300 minutes.Feeding manner to the epihalohydrin compound is not specifically limited, and it can just all drop at the beginning, or continuously, or drop into unceasingly.
If need, the cationic polymeric dispersion of the present invention that makes thus can have a kind of alcohol amine compound in the presence of heat-treat.What the sheet resistance that provides the aqueous dispersion that obtains by this heat treatment method was further reduced films.
Used alcohol amine compound comprise monoethanolamine, diethanol amine, triethanolamine, isopropanolamine, diisopropanolamine (DIPA), triisopropanolamine, dihydroxy-propylamine, two (dihydroxypropyl) amine, three (dihydroxypropyl) amine, or the like.In addition, can also use the polyamines-polyhydroxy-alcohol compound that obtains by the reaction of alkylene oxide and polyamines, for example the addition compound product of the addition compound product of oxirane (4 moles) and ethylenediamine, oxirane (4 moles) and propane diamine etc.In the middle of these alcohol amine compounds, best is diethanol amine.
In per 100 parts (moles) amino of existing in the ethylene copolymer is benchmark, and the addition of alcohol amine compound is 20 to 200 parts (mole), and is good with 50 to 150 parts (mole).Addition is lower than 200 parts and is not enough to produce the effect that the surface resistivity of filming that the desirable aqueous dispersion that makes gained makes reduces.On the other hand, if the consumption of alcohol amine compound surpasses 200 parts, then since in the resulting aqueous dispersion excessive compound have neither part nor lot in reaction, what make thus films not only evenly but also is hygroscopic, the result causes the humidity dependence of surface resistivity to rise.
Generally carry out (being advisable with 40 to 100 ℃) under temperature is 20 to 100 ℃ condition with the reaction of alcohol amine compound, the reaction time is 1 to 10 hour.
The solid content of cationic polymeric dispersion of the present invention is preferably in per 100 parts of (weight) water 5 to 50 parts (weight), and 10 to 40 parts (weight) is better.Said herein " solid content " is meant the content that removes the afterwards remaining nonvolatile matter that anhydrates by method dry in about 100 ℃ of hot-airs in aqueous dispersion.Solid content surpasses 50 parts aqueous dispersion owing to viscosity does not have flowability and its property used (as the performance that applies) poor too greatly on matrix.From the angle of production efficiency, transportation, selling price and the coating dry load in back, it also is worthless that solid content is lower than 5 parts aqueous dispersion.
In film-forming process, this aqueous dispersion is coated with on the butt body (as paper and plastic film), and under about 50 ℃ to 150 ℃ condition heat drying.
When with aqueous dispersion of the present invention during as the conductive layer of electric imaging recording materials, it can be mixed mutually with metal-oxide semiconductor (MOS), for example can mix with zinc oxide, cuprous oxide, indium oxide, tin oxide, titanium oxide, cobalt oxide, nickel oxide, tantalum pentoxide, vanadic anhydride, tungstic acid, molybdenum trioxide etc. or these metal oxides that are mixed with adulterant.Being used in combination these metal oxide semiconductor materials can further reduce the surface resistivity of resulting conductive layer effectively and reduce the dependence of packing density to humidity.
In order to make acrylic resin, vinyl chloride resin, butyral resin etc. have writing quality, sign performance or natural material sensation, the coating of using the pigment (as titanium oxide, calcium carbonate, starch, clay etc.) that wherein contains the microparticle shape usually is as the dielectric layer resin solution that imposes on the semiconductor laminated sheet material (making by aqueous dispersion of the present invention being coated in method dry then on paper or the plastic film).The thickness of this class coating is about 5 to 10 microns (dry state).Its surface resistivity is preferably about 10 under normal temperature and atmospheric pressure
12To 10
15Ω (ohm).
Also can add additive, for example dyestuff, pigment, stuffing, surfactant, antistatic additive, plasticizer, lubricant, dispersant, defoamer etc., and water-soluble resin, for example polyvinyl alcohol as required in the aqueous dispersion of the present invention.
According to the present invention, can obtain by aqueous dispersion being coated to subsequent drying on paper or the plastic film that one deck is thin, transparent, the filming of soft and tough.Dried coating is non-water-soluble, and moist and water are had goodish stability.Like this, the packing density that contains the electric imaging recording materials of aqueous dispersion of the present invention in the conductive layer be subjected to the little and record performance of the influence of humidity not in time passing and change.When with this aqueous dispersion during as antistatic additive, resulting film has lasting antistatic property.
In addition, in the sheet material forming process, use aqueous dispersion of the present invention the gluing performance and the wet strength of paper are significantly improved as additive.Both aqueous dispersion can have been joined as wet boundary effect (wet end) additive in this class is used also to make it be impregnated in the paper in the paper pulp.In the previous case, generally be that the cationic polymer that is scattered in the water is joined in the paper pulp by the consumption of per 100 parts of paper pulp (dry state weight) 0.1 to 5 part (weight), then the paper that forms in temperature be under 70 to 150 ℃ the condition heating several seconds to a few minutes make its drying.In this case, can be used in combination the water repellent, as wax, polysiloxanes and fluorocarbon resin etc.
