Description
Technical field
The invention belongs to the macromolecule chemical industry technical field, specifically a kind of paste resin that is used for production (pickling process) PVC gloves for preparing by the microsuspension method and preparation method thereof.
Background technology
Present domestic pvc resin paste grade product has multiple production method, and wherein main method has letex polymerization and microsuspension.The paste rosin products trade mark of its production is numerous, is mainly used in coating, foaming, slush moulding, dips in and mould and complete processing such as rotation-formed, produces goods such as leatheroid, flooring laminate, wallpaper, flame-retardant conveyor belt and toy.
The PVC gloves of dip forming are used for the labour protection of medical worker and other industries, because traditional emgloves white man skin produces anaphylaxis, thereby the PVC gloves are exported states such as the U.S., Europe and Australia in a large number.China PVC gloves have 80% outlet approximately, produce required PVC paste resin and account for 50% of China's paste resin total quantity consumed, and the manufacturing enterprise of China uses the import pvc resin paste grade to be raw material always.Numerous domestic is stuck with paste in the resin trade mark does not still have the resin dedicated of suitable for producing gloves.The present invention provides the resin dedicated of substituting import one products production PVC gloves for the sector.
Summary of the invention
Purpose of the present invention provides a kind of microsuspension by vinylchlorid, the primary particle median size that makes product be 1.0 μ m～2.0 μ m dispersion type polyvinyl chloride homopolymer (paste resin) be used to paste resin of producing by the PVC gloves and preparation method thereof
The object of the present invention is achieved like this: its technical scheme comprises following monomeric chemical ingredients composition and prescription thereof:
Vinyl chloride monomer 100% (wt), account for monomer weight 0.5%～0.8% emulsifying agent, account for the Fatty Alcohol(C12-C14 and C12-C18) of monomer weight 0.9%～1.1%, account for the oil soluble composite initiator of monomer weight 0.007%～0.010%;
Emulsifying agent is one or more arbitrary proportion blended aniorfic surfactant, and this anion surfactant is hard soap, long chain alkyl sulfates, aromatic sulfonate, sodium laurylsulfate, hexadecanol sodium sulfate, sodium lauryl sulfate, Sodium dodecylbenzene sulfonate, tetradecyl benzene sulfonic acid sodium salt:
The oil soluble composite initiator is one or both azo classes and the combining of one or more peroxide initiators, and wherein the azo class is Diisopropyl azodicarboxylate, 2,2'-Azobis(2,4-dimethylvaleronitrile); Superoxide is dicyclohexyl peroxydicarbonate, di-isopropyl peroxydicarbonate, peroxy dicarbonate hexichol oxygen ethyl ester and ethoxyethyl peroxy dicarbonate.
The present invention comprises that also the Fatty Alcohol(C12-C14 and C12-C18) that adds to some extent makes the more stable high fatty alcohol or the higher fatty acid of dispersion liquid of microsuspension for one or more.
The present invention also includes and adds an amount of oxidative ethane or epoxypropane polymer as the viscosity modifier ring.
Preparation method of the present invention is: scope is got vinyl chloride monomer, pure water, emulsifying agent and initiator after dispersion machine disperses according to the above ratio, make it to form fine droplets, under the effect of oil-soluble initiator,, generate polyvinyl chloride homopolymer-latex in 40～60 ℃ of reactions 10～30 hours.Operations such as latex is spray-dried, cloth bag filtration, pulverizing, packing make pvc resin paste grade.
Emulsifying agent generally uses aniorfic surfactant.Anion surfactant such as hard soap, long chain alkyl sulfates, aromatic sulfonate, sodium laurylsulfate, hexadecanol sodium sulfate, Sodium dodecylbenzene sulfonate, tetradecyl benzene sulfonic acid sodium salt etc.Its consumption is 0.4%～1.2% (wt) of monomer consumption.Higher alcohols that uses in the emulsification system or higher fatty acid etc. are as dispersion aids, its purpose is to reduce the interfacial tension of vinylchlorid and water, make tiny dispersant liquid drop in polymerization process, keep the stability of drop effectively, do not take place to assemble and layering, behind the latex that forms polymkeric substance, can make it keep stable again.But the stabilising effect of the dispersion liquid of carbonatoms below 8 is not good, should select carbonatoms more than 8, and consumption is 0.6%～1.5% (wt) of monomer consumption, preferably select 0.9%～1.2% for use.
Initiator generally uses azo class and peroxide azo class that Diisopropyl azodicarboxylate, 2,2'-Azobis(2,4-dimethylvaleronitrile) etc. are arranged usually; Superoxide is dicyclohexyl peroxydicarbonate, di-isopropyl peroxydicarbonate, peroxy dicarbonate hexichol oxygen ethyl ester and ethoxyethyl peroxy dicarbonate, the positive caproyl superoxide of 3.3.5-trimethylammonium etc.; consumption is 0.005%～0.012% (wt) of monomer usage quantity, preferred 0.006%～0.01%.Initiator system can use wherein two kinds compound.
The selected polymerization temperature of the present invention is advisable with 40～50 ℃.
Composite initiator of the present invention is composited by a kind of azo class and a kind of peroxide.
Emulsifier system of the present invention is made up of a kind of aniorfic surfactant and a kind of Fatty Alcohol(C12-C14 and C12-C18).
The reaction system material dispersed time of the present invention is 40～60min.
The present invention and additive method are compared, and have following characteristics:
1. adopt composite initiator system to make the speed of response held stationary;
2. the adding of dispersion stabilizer is guaranteed to stir down dispersion liquid and still can be kept stable;
3. polymerization latex good stability;
4. gained paste stable resin is good;
The viscosity stability of plastisol is good, through the time change little.
To be described in further detail invention by example below, but following example only is the present invention's example wherein, the rights protection scope of not representing the present invention and being limited, the scope of the present invention is as the criterion with claims.
