Abstract
The invention provides a green and environment-friendly film-forming auxiliary agent applied in coatings and a use method thereof, relating to a green and environment-friendly film-forming auxiliary agent applied in coatings and a use method thereof. The green and environment-friendly film-forming auxiliary agent consists of effective components, i.e. a component A and a component B. The mass ratio of the component A and the component B is 10:0.1-0.2, wherein the component A is selected from one of ester compounds, and the component B is selected from one or more of organic polyatomic alcohols. The invention can reduce the lowest film-forming temperature of the emulsion polymer, has little solubility in water, has certain volatility, can be stopped in a coating film to perform function in the film-forming process, is volatilized wholly after forming the film, has good film-forming effect and low VOC index, is non-toxic and environment-friendly, and has the function of enhancing dispersion and uniformity of the paint and film-forming stability.
Description
Technical field:
The present invention relates to a kind of environmental protection film coalescence aid and using method thereof that is applied in the coating.
Background technology:
At present, building coating occupies very consequence in coatings industry, fast development along with China's building and adnornment industry, people are to the continuous enhancing of improving constantly of requiring of quality of life and environmental consciousness, and coating industry is further strict to the control of VOC (boiling point is lower than 250 ℃ content of volatile organic compound).Water emulsion coating as one of finishing material has become the material of main part that inner wall of building is decorated, the decorating outer wall of building utility ratio also reaches 35% simultaneously, and the many emulsion polymers that use in emulsion paint can't form film at normal temperatures, and most at low temperatures emulsion polymers can not form film.For making emulsion paint form complete smearing; so must add the film coalescence aid that can play coalescence effect; film coalescence aid is the very strong and volatility of solvability solvent very slowly normally; it claims flocculation agent, coalescing agent again; can make polymer particle swelling, compressive deformation, thereby reduce the minimum film-forming temperature of emulsion and emulsion paint.They can soften the emulsion polymerization composition granule, these particles coalesces are merged, form film better, film coalescence aid except that reducing emulsion paint minimum film-forming temperature (MFFT), but can also improve the weathering resistance scrubbing character of emulsion paint, the paint film properties such as color developing of coating.The film coalescence aid kind of using in coating industry at present is a lot, mainly contain phenylcarbinol, the propylene glycol phenylate, the butoxy butyl propionate, butyl glycol ether, propylene glycol phenylate, 12 carbon alcohol esters, hexylene glycol monobutyl ether acetate etc., yet they are used in coating material production and have different defectives: have with the emulsion consistency is good but smell is bad, stability to hydrolysis is bad, causes flocculation; The VOC height that has is bad to environment and human body; The performance that has is single can not to be satisfied levelling property and can not prevent pigment caking and coating skinning.
Summary of the invention:
The purpose of this invention is to provide a kind of environmental protection film coalescence aid and using method thereof that is applied in the coating, it can reduce the minimum film-forming temperature of emulsion polymer, solubleness is little in water, has certain volatility, can be trapped in the film process and play a role in filming, all volatilizations after the film forming, film-formation result is good, the VOC index is hanged down asepsis environment-protecting, have the dispersing of pigments of enhancing and stepless action and film forming stability, effective especially in light and semi-gloss paint are arranged, absorbed by emulsion particle easily, good cohesiveness and color developing, stability in storage, the levelling property of raising coating, gloss, saturation ratios etc. are to the scrub performance of paint film, the moving stability of melting, sticking power, physical strength all has certain effect.
In order to solve the existing problem of background technology, the present invention is by the following technical solutions: it is made up of effective constituents A component and B component, the mass ratio of A component and B component is 10:0.1-0.2, wherein: the A component is selected from a kind of of ester compound, and the B component is selected from one or more of organic polyhydric alcohol.
Described A component is 2.4-trimethylammonium-1.3-pentanediol mono isobutyrate (alcohol ester-12) or dimethyl phthalate (dmp); The B component is ethylene glycol or propylene glycol.
Described film coalescence aid is added in the coating manufacturing with the mass concentration that is not less than 2%-6%.
Addition of the present invention depends primarily on the hardness of letex polymerization, harder emulsion add-on that should be softer just can reach identical film-formation result greatly, generally speaking, the pure-acrylic emulsion addition is 2-5%, is 2-4% for the acrylate and vinyl acetate emulsion addition, is generally 4-6% for benzene emulsion, in addition, use the different ingredients of same emulsion, also can require different add-ons, can follow when use temperature is low and add in right amount according to situation.The present invention can add in any stage of system lacquer, if can add at twice, more can give full play to its effect.In process of lapping, add 1/2 amount, help the wetting of color stuffing and dispersion, add 1/2 amount, help to suppress foamy and produce in the paint stage.
The present invention can reduce the minimum film-forming temperature of emulsion polymer, solubleness is little in water, has certain volatility, can be trapped in the film process and play a role in filming, all volatilizations after the film forming, film-formation result is good, and the VOC index is hanged down asepsis environment-protecting, has the dispersing of pigments of enhancing and stepless action and film forming stability, it is effective especially in light and semi-gloss paint are arranged, absorbed good cohesiveness and color developing, stability in storage easily by emulsion particle, improve the levelling property of coating, gloss, saturation ratio etc., to the scrub performance of paint film, the moving stability of melting, sticking power, physical strength all has certain effect.
