Description
Technical field
The present invention relates to decorative paint technical field, be specifically related to a kind of compounding and brighten slurry and use its interior wall latex
Paint.
Technical background
China's more authoritative coating process one book of coating circle is defined such that " coating is a kind of material, this material
Can be coated in object surface by different construction technologies, formation adheres to firmly, has some strength, continuous print solid film.
The film common name film so formed, also known as paint film or coating." water emulsion paint for internal wall must have good as a kind of ornament materials
Good dicoration and the feature of environmental protection, the most just comprise whiteness index.Emulsion paint whiteness is summarized: CIE committee regulation D65 light source is
Standard light source, the fully reflective body of W100 is reference standard, and the CIELAB system that CIE formulates is existing international colour examining mark
Standard, this standard has been carried out derivative defining existing emulsion paint field and using Wb whiteness by China.Whiteness combines tone with bright
Spending two kinds of factors, the height of whiteness has become as the important value composition of interiro wall latex paint.
Titanium dioxide is described as the Chinese white that performance is best in the world at present, and its whiteness Producing reason is owing to it has
High refractive index and opacifying property.Coating would generally be used the titanium white of two kinds of crystal formations: rutile titanium dioxide cost is high, has simultaneously
Higher refractive index and covering power；Anatase titanium dioxide cost is lower slightly, and the same footpath shortwave reflecting effect having is better than rutile, but
Being that anatase titanium dioxide is big owing to polluting in production process, crystal formation is unstable, and gradually by social cleaning, it is right that the part of anatase titanium dioxide substitutes
Overall performance and gloss etc. all adversely affect.
In economical emulsion paint, whiteness is not typically the most the highest, high by improving titanium white efficiency low cost merely.Therefore, I
To find a kind of non-titanium white, more efficient, environmental protection, the method promoting interiro wall latex paint whiteness of low cost.This method
Exploitation will be grasped the opportunity in advance in the game of Red sea for enterprise.
Invention particular content:
One object of the present invention provides a kind of compounding brighten slurry and use its interiro wall latex paint, such that it is able to make
The whiteness of interior wall coating increases to more than 92%.
For achieving the above object, the technical scheme that the present invention is concrete is:
A kind of compounding brightens slurry, it is characterised in that comprise following components by mass percentage:
Preferably, described brightening agent is UV05-[2,2 '-(1,2-ethylene diyl) two [5-[[4-[two (2-hydroxypropyl) ammonia
Base]-6-[(4-sulfophenyl) amino]-1,3,5-triazines-2-ethyl] amine] benzenesulfonic acid sodium salt.
The compounding preparation method brightening slurry as above, it is characterised in that first add brightening agent also in pure water
Stirring at low speed is disperseed 5 minutes, is subsequently adding the dispersion of hydroxyethyl cellulose low speed and is sufficiently mixed, fully lower-speed state after mixing
Dropping SN-5040 polycarboxylate sodium's surfactant, until described the compounding of the formation that stirs brightens slurry.
A kind of use compounds the interiro wall latex paint brightening slurry as mentioned above, it is characterised in that described interiro wall latex paint is pressed
Mass percent, comprises following components:
Described adjuvant includes following components
Calcined kaolin 3.5%～10%
Calcium carbonate 30%～45%
Aluminium silicate 0%～10%.
The all raw material used in interior wall coating of the present invention is mainly water paint component, is the most easily taking
, cost is the highest.
The preparation method of above-mentioned interiro wall latex paint, it is characterised in that comprise the following steps:
(1) premix: accurately add pure water, under the rotating speeds of 400～600 revs/min stir, accurately adds cellulose thickening
Agent, and it is sufficiently stirred for until complete swelling；Accurately add dispersant, stir；Stirring the most accurately adds rutile-type
Titanium dioxide and adjuvant, after inventory accounts for total powder amount 2/3, adjustment of rotational speed to 1200～1600 rev/min, rate of feeding is with powder
Material is not piled up and is advisable, and stirs 15～20 minutes；
(2) latting drown: adjustment rotating speed, to 500～800 revs/min, is sequentially added into film former, defoamer and antifungus agent, finally
Add to compound and brighten slurry, stir；Latter auxiliary agent just can be added after former auxiliary agent must be waited to stir,
Rear stirring 5～i.e. can get described interiro wall latex paint in 10 minutes；

Inventive principle illustrates:
First pass through in common interior wall styrene-acrylic latex coating, add brightening agent according to different ratio, do not changing former latex
In the case of paint covering power, play the effect increasing dry film whiteness.Brightener species is various, but is broadly divided into 6 classes: 1) hexichol
Vinyl；2) benzoxazoles class；3) Coumarins；4) double piperazine Ammonias；5) pyrazolines；6) Phthalimide class.Above-mentioned product
Apoplexy due to endogenous wind represents the trade mark such as: the diphenylethylene ER trade mark has obvious residues of formaldehyde in building-up process, and coating VOC is had great shadow
Ringing, the anti-sublimation reliability of the benzoxazoles class DT trade mark is the best, also domestic environment can cause secondary pollution jeopardize health, tonkabean
The element class SWN trade mark, the pyrazolines AD trade mark, the Phthalimide class APL trade mark whole dye process that is mainly used in weaving all does not dissolves in
Water, the Coumarins ANB trade mark can produce serious flocculation for coating system, and the diphenylethylene VBL trade mark, the CXT trade mark have research
Prove that it has direct carcinogenecity especially.Diphenylethylene as the big class of water-soluble whitening agent, be mainly used in papermaking, coating and
In soapmaking class production process.By Preliminary screening, finally determine and carry out with water miscible diphenylethylene and benzoxazoles class
Experiment.
Table 1: brightening agent adds the ratio in new formula and whiteness change table to:
As known from Table 1: owing to solid-state brightening agent is along with the increase of consumption, in emulsion paint system, degree of scatter can be deteriorated,
As seen from the above table when CBS-X and OB-1 brightening agent consumption is more than 2.0 ‰, hence it is evident that visible dry film coating has uneven speck,
And whitening effect is also not as liquid brightening agent.Liquid brightening agent whitening effectiveness when addition is more than 8 ‰ is substantially deteriorated.
The impact on new laboratory milk shellac varnish system viscosity of the table 2 liquid brightening agent
As shown in Table 2: when in the online adding procedure of liquid brightening agent addition more than 6 ‰ time have the great increase of viscosity existing
As, and feel brushing experiment of constructing substantially is deteriorated, system viscosity is affected very by anionic brightening agent such as brightening agent APC
Greatly, therefore finally selected brightening agent UV05-[2,2 '-(1,2-ethylene diyl) two [5-[[4-[two (2-hydroxypropyl) amino]-6-
[(4-sulfophenyl) amino]-1,3,5-triazines-2-ethyl] amine] benzenesulfonic acid sodium salt] carry out serial experiment.This brightening agent is one
Plant lewis base soluble in water, have, at big π key two ends, the electronics moved freely, can make in valence band under ultraviolet lighting effect
Electronics reduce, outside transition forms the relatively low royal purple light of energy, and then offsets a part of gold-tinted effect, promotes the dry of emulsion paint
Film whiteness.This is planar carbon chain structure, and proportion is 1.10～1.20, pH8.0～10.0 under room temperature.Brightened by selected UV05
Agent, carries out gradient experiment and determines the whitening effect of brightening agent.
UV05 is as a kind of 4 sulfonic acid group brightening agents, and fluorescence intensity is not strong, will not produce green change when excess is added, very
The phenomenon become to ash, although after UV05 is in an experiment by 6 ‰ interpolations, experimental formula whiteness can be brought up to from 86.32%
88.19%, UV05 improve 1.87% to whiteness, but compared with target whiteness 92%, experiment sample whiteness still has bigger difference.
Secondly, after fully taking into account the factor of whitening effect, construction feel and viscosity, disperseed adequacy as experiment
Variable, attempts the loading by brightening agent Yu cellulose, thus preferably disperses attachment.Owing to brightening agent is anionic nature
, brightening agent can well disperse in the solution, due to the polar attraction of cellulose surface functional group, makes brightening agent preferably inhale
It is attached to cellulose surface.When brightening agent can have more chance to be fully combined with cellulose when leading portion adds, and have longer
Jitter time.Now We conducted the loading combine experiment of brightening agent and variable concentrations cellulose.
In technique: in pure water, preferential brightening agent stirring at low speed of adding is disperseed, and then adds cellulose and is allowed to be sufficiently mixed
Dispersion, forms the high white slurry of compounding cellulose.
First preliminary experiment goes out compounded formula 1 following (by mass percentage):
Pure water: 92%～93%；
Brightening agent: 6%；
Hydroxyethyl cellulose: 1%～2%；
Add 1# compound size 10% by leading portion, with the brightening agent that back segment adds 6 ‰, form equivalent and add contrast.
With the new formula of viscosity is tested table before and after table 3 brightening agent is compounding
As shown in Table 3: obviously above measure whiteness is slightly improved, and disperses and is attached to leading portion really have lifting, work as fiber
When the addition of element is less than 1.5%, quantity is very few, and the attachment on brightening agent affects very little, when cellulose consumption is more than
In 1.5% time, whiteness slightly promotes.Therefore determining that useful loading capacity is 1.5%, concrete increment also will be according to system overall viscosity
Design.May be along with in adjuvant adition process, two trivalent metal ions of adjuvant hydrolysis create murder by poisoning to free brightening agent,
Weaken it and improve effect.
Again, it is contemplated that above-mentioned factor, can we attempt being tied with anion surfactant by free brightening agent
Close, form cellularity, so protect its after later stage powder adds the high volence metal ion of powder dissolution to its scattered poison
Evil, and negative electric field mutual exclusion and stable dispersion under the group effect of same anion.Above system is lived by addition surface
Property agent compound, be combined the maximum dispersion reaching fluorescent whitening agent by two steps.
In technique: add stirring at low speed dispersion in brightening agent by preferential in pure water, be subsequently adding low speed in cellulose
Dispersion is sufficiently mixed, last lower-speed state dropping SN-5040 polycarboxylate surfactant, until the compounding fibre of the formation that stirs
The high white slurry of dimension element.
Further experiment goes out compounded formula 2 following (by mass percentage):
Pure water: 83.5%～93.5%；
Brightening agent: 6%；
Hydroxyethyl cellulose: 1.5%；
SN-5040 surfactant: 0%～9%.
Table 5 SN-5040 different proportion compound size is used for new formula 1# with number brightening agent whiteness table
As shown in Table 5: experiment finds, when brightening agent is less than 1: 1.1 with Surfactant Ratio, to continuously add big scale
Not only brightening agent will not be played more preferable protective effect by face activating agent, the effect that fluorescence is cut down can be produced on the contrary, make plane structure
The brightening agent of type accesses the surfactant of excess, reduces the activity of its big π key, the most a large amount of free molecules be wrapped by and can not
Combine with cellulose.Dispersion be not sufficient to ensure that its effect in powder and emulsion paint, due in the dispersion of later stage powder also
Have partially stabilized breaking, only when the consumption of surfactant reaches dynamic equilibrium in dispersion and pockets of effect, system
Could really reach stably to brighten and maximize with whitening effectiveness.When brightening agent and Surfactant Ratio are 1: 0.9～1: 1.1
Time, interior wall formula has preferable whiteness.
The compounded formula finally determined is as follows:
Pure water: 85.9%～87.1%；
Brightening agent: 6.0%；
Hydroxyethyl cellulose: 1.5%；
Polycarboxylate sodium's surfactant: 5.4～6.6%.
Complex process: add stirring at low speed dispersion 5 minutes in brightening agent by preferential in pure water, be subsequently adding cellulose
The dispersion of middle low speed is sufficiently mixed, fully lower-speed state dropping SN-5040 polycarboxylate surfactant after mixing, until stirring is all
Even formation compounds the high white slurry of cellulose.
The summary present invention improves the mechanism of whiteness: introduce brightening agent, by the shortwave black light to rutile titanium dioxide
The reflection of some light and transmitting, improve overall whiteness, simultaneously improves the loading attachment of brightening agent in several ways, leading portion divides
Dissipate property to promote, and the cladding protective effect that surfactant micellar is to free brightening agent, in emulsion paint, jointly promote increasing
White effect.The compounded formula formed by brightening agent brightens slurry through cellulose and the compounding of surfactant, finally interior
Wall formula has reached the whiteness of more than 92% with the scheme of best price/performance ratio.
It is an advantage of the current invention that: other raw materials of use are mainly water paint component, are the most easily obtaining,
Cost is the highest.Brightening agent below the consumption of 6 ‰, compounding by a series of conventional materials and auxiliary agent, just can make to commonly use interior wall
The whiteness of emulsion paint rises to more than 92%.
Beneficial effect:
What interiro wall latex paint creative use of the present invention multistep was compounding brightens slurry, improves in original emulsion paint single
During one use brightening agent, the drawback of whitening effect difference, plays the effect of brightening agent further, reduces unit cost.And coating
Other compositions do not change, so the main performance of coating does not all change, other require not change, and meet GB/
Indices in T9756-2009 standard, meets nuisance in GB/18582-2008 indoor decorating and refurnishing materials interior wall coating
Matter is limited the quantity.Compared with general water paint, present invention cost of raw material when promoting identical whiteness is lower, has higher product
Competitiveness and wide market prospect.
