A kind of anaglyphy paint and preparation method thereof
Technical field
The present invention relates to a kind of art coatings, particularly a kind of anaglyphy paint and preparation method thereof.
Background technology
Art coatings originates from Europe, and advanced technique is also spread by Europe and comes, after entering domestic market, with the decorated style of its novelty, and unusual decorative effect, doubly welcomed by the people and high praise.Art coatings is a kind of novel wall decoration art paint, adds the treatment process of modern high technology, makes product nontoxic, environmental protection, and also possess waterproof and dustproof and the function such as fire-retardant, high-quality art coatings can criticize brush simultaneously, and adsorptivity is strong, and color sustains its quality through age.
Textured paint is a series in art coatings, and textured paint is the colored metope coating material that a kind of match volume is true to nature.Metope after decoration exactly likes three-dimensional perception effect as embossment, so be referred to as anaglyph.Textured paint is not only a kind of brand-new decorative art
coating, the perfection performance of decorative art especially.Enhancing volatile organic compounds (Volatile Organic Compound is called for short VOC) along with people's environmental consciousness more and more receives the concern of the public and is strictly limited, although control VOC has become promote that Main Means VOC of water emulsion coating for solvent based coating of building coating Sustainable development reduces greatly, but owing to still containing the low molecule organic volatiles such as a certain amount of film coalescence aid frostproofer in water-borne coatings, they constitute the main source of latex coating VOC, how to reduce VOC further, improving environment friendly is the important developing direction of Architectural Emulsion Paints.
Summary of the invention
In view of this, an object of the present invention is to provide a kind of anaglyphy paint, and have lower free formaldehyde content, environmental protection, good waterproof performance, paint film is full, and strong through spray gun spraying artistic feeling, other performances meet relevant specification of country.
The present invention is solved the problems of the technologies described above by following technique means:

Epoxy modified acrylic resin introduces propenyl unsaturated double-bond at the two ends of epoxy molecule chain, then with other monomer copolymerizations, make the various premium propertiess of epoxy resin, adhesive power be strong, molding shrinkage is low, chemical stability is good, electrical insulating property and Heat stability is good etc.
Flow agent adopts and can impel coating in drying and forming-film process, form smooth, smooth, a uniform film.Can effectively reduce
cover with paint, lacquer, colour wash, etc.liquid
surface tension, improve it
levelling propertywith a class material of homogeneity, can improve and cover with paint, lacquer, colour wash, etc. liquid
perviousness, the possibility producing spot and spot when brushing can be reduced, increase spreadability, make film forming even, natural.
Wetting agent adopts non-ionic wetting agent, mainly containing simple function group, oleoyl alkylene oxide block multipolymer, to color stuffing dissemination, and improves color developing.
Defoamer is the one in non-ionic type defoamer, molecular antifoaming agent, has good consistency and can principal characteristic.
Further, composed of the following components by weight: epoxy modified acrylic resin part 88-92 part, film coalescence aid 2.0-3.0 part, flow agent 0.7-1.2 part, dispersion agent 0.3-0.4 part, wetting agent 0.5-0.65 part, defoamer 1.0-1.1 part, 1250 order talcum powder 18-23 parts, thickening material 2.5-3.0 part, sterilant 4-6 part, pH adjusting agent 0.6-0.7 part, water 40-55 part.
Further, composed of the following components by weight: epoxy modified acrylic resin part 90 parts, film coalescence aid 2.5 parts, flow agent 1.1 parts, dispersion agent 0.35 part, wetting agent 0.6 part, defoamer 1.0 parts, 1250 order talcum powder 22 parts, thickening material 2.8 parts, 5 parts, sterilant, pH adjusting agent 0.65 part, 50 parts, water.
Further, described film coalescence aid is one in dipropylene and dipropylene glycol methyl ether or two kinds of mixing arbitrarily.Film coalescence aid contributes to film forming matter film forming at low temperatures.
Further, flow agent is polyether polyester modified organic silicon oxygen alkane flow agent, be greatly improved by the consistency of polyethers, polyester modification siloxanes and resin, reduce surface tension, the effect of the ability that control surface flows, the slip that increases, nonshrink hole, antiblocking is also all fine.
Further, described sterilant adopts not containing the isothiazolinone disinfecting agent of VOC, has thermotolerance, plays sterilization and anticorrosion effect simultaneously.
The present invention also provides a kind of preparation method of anaglyphy paint, specifically comprises the following steps:
A. for subsequent use by above-mentioned formula feeding;
B. in mixing machine, add water, then add sterilant, wetting agent, dispersion agent and flow agent successively in water, with the speed of 600 revs/min DEG C blending dispersion 6 minutes;
C. in described dispersion liquid, epoxy modified acrylic resin, film coalescence aid, defoamer and talcum powder is added successively, with the speed of 1500 revs/min DEG C blending dispersion 10 minutes;
D. in described dispersion liquid, add thickening material and pH adjusting agent, with the speed of 800 revs/min DEG C blending dispersion 5 minutes, the pH value range of described dispersion liquid is adjusted to 8-8.5.
Beneficial effect of the present invention: the anaglyphy paint obtained by special formulation and preparation method, not only there is existing textured paint there is waterproof, dust-proof, the feature of good flame retardation effect, also there is lower free formaldehyde content, paint film is full, and strong through spray gun spraying artistic feeling, other performances meet relevant specification of country.
