Description
Technical field
The present invention relates to paint fields, and in particular to a kind of waterproof stain resistant aqueous inner wall paint for kitchen use and its preparation side
Method.
Background technique
Latex paint is still the first choice of internal wall finishing at present, and traditional latex paint anti-pollution characteristic and waterproof performance all compared with
Difference.With lotion synthetic technology be constantly progressive and gradually the coming into the open of latex paint formulations, transparence, the property of latex paint
It can be remarkably enhanced, also occur the one-component latex paint of many leading " strong resistants " on the market.Compared to traditional cream
Glue coating, anti-pollution characteristic have certain promotion really, but in this high oil smoke surroundings in high " pollution " environment, especially kitchen,
Metope is easily stain by greasy dirt, and even this kind of " strong resistant " coating still can leave after wiping the oil smoke of surface contamination
Obviously trace, degree of contamination are limited.In addition, kitchen is the place of moist more water, since one-component latex paint is formed
Film compactness it is general, hardness is lower, after the wiping that gets wet for a long time, the easy mildew of film, breakage, blistering even fall off.
It would therefore be highly desirable to which it is aqueous to develop that a kind of compactness is good, hardness is high, the environmental protection of washability, waterproof, anti-pollution characteristic are excellent
Coating, especially resistance to kitchen fume.

Beneficial effects of the present invention:
Traditional one pack system acrylic acid interiro wall latex paint, membrane formation mechanism are the volatilizations with moisture, the polymer in coating
Particle, pigment, seasoning granules etc. are gradually drawn close, and reach tightly packed, and when environment temperature is higher than minimum film formation temperature, lotion is poly-
Polymer beads deformation, film coalescence.Although macroscopically paint film is continuous, from microstructure, paint film is by emulsion polymer
Particle, which closely coalesces, squeezes formation.Therefore, subtle gap is certainly existed between particle and particle, fundamentally results in list
There are obvious shortcomings for the paint film anti-pollution characteristic of part acrylic interiro wall latex paint.The existing side for promoting interior wall coating anti-pollution characteristic
Method can only improve the gap between paint film particle to greatest extent, or addition surface of the paint film protects auxiliary agent, can not be inherently
Solve the problems, such as that one pack system acrylic acid interiro wall latex paint is applied to encountered in " high pollution " environment.
The present invention uses waterborne epoxy modified acrylic lotion as film forming matter, can be with self film；It is solid with modified amine
After agent mixes according to a certain percentage, in film forming procedure, epoxy group and amino interreaction form the company in microstructure
Continuous film inherently solves the problems, such as that spot is permeated, therefore can be the kitchen of environment such as, humidity more suitable for oil smoke, realization
Waterproof stain resistant.
