CN103627272B - Liquid rock particles of artificial granite sand textured coating - Google Patents

Abstract

The invention discloses liquid rock particles of an artificial granite sand textured coating. The artificial granite coating is excellent in texture performance, crack resistance, weather fastness and dirt resistance, and also has excellent simulation on natural stone. The liquid rock particles of the artificial granite sand textured coating are prepared from an elastic acrylic emulsion, titanium dioxide, natural painted sand, inorganic powder, inorganic gel, a setting agent, an antifreeze agent, a defoaming agent, a bactericide, a dispersant, an alkali swelling and thickening agent, a cellulose thickening agent, a wetting agent, a coalescing agent and water. The liquid rock particles are capable of causing the decoration effect of the artificial granite coating to be vivider and also causing the artificial granite coating to have excellent weather fastness, acid-base resistance and hardness and natural color and gloss just as the natural stone; the liquid rock particles are used in the artificial granite sand textured coating to achieve the imitation stone effect of single-gun multiple colors.

Description

A kind of Liquid rock grain of artificial granite sandy paint

Technical field

The Liquid rock grain of what the present invention related to is a kind of artificial granite sandy paint, belongs to building material field.

Background technology

Artificial granite paint has good texture performance, cracking resistance, weathering resistance and anti-pollution, and has the emulation good to lithotome.But, the imitative hardcore that traditional artificial granite paint uses is the color sheet of high molecular polymer latex, the petrochemical materials that its need of production consumption is a large amount of, the electric energy of at substantial also wanted by production unit, and complex manufacturing, experience dispersion, grinding, filtration, roller coating, airing, the demoulding, freezing, broken, tens procedures such as sub-sieve, packaging, produce waste water, solid waste and dust pollution in process of production.Therefore, provide a kind of Liquid rock grain of artificial granite sandy paint, promote the decorative effect of artificial granite paint, improve weathering resistance, the resistance to acids and bases of coating, hardness and naturally color and gloss are necessary.

Summary of the invention

The object of this invention is to provide a kind of Liquid rock grain of artificial granite sandy paint, make the decorative effect of artificial granite paint more true to nature and there is the good weathering resistance of lithotome, resistance to acids and bases, hardness and naturally color and gloss.Overcome tradition and prepare a large amount of petrochemical materials of needs consumption existing for artificial granite sandy paint, the deficiency of at substantial electric energy also wanted by production unit.

Foregoing invention object, is achieved through the following technical solutions: a kind of Liquid rock grain of artificial granite sandy paint, is prepared from by the component of following percent by weight: elastomeric propylene yogurt liquid 10%-50%; Titanium dioxide 10%-15%; Natural colour sand 5%-8%; Inorganic powder 3%-5%; Inorganic gel 2%-5%; Setting agent 3%-5%; Antifreezing agent 1%-2%; Defoamer 0.3%-0.8%; Sterilant 0.1%-0.15%; Dispersion agent 0.1%-0.4%; Alkali swollen thickener 1%-1.5%, cellulose thickener 0.1%-0.2%; Wetting agent 0.1%-0.15%; Film coalescence aid 0.5%-1%; Surplus is water;

The preparation method of the Liquid rock grain of artificial granite sandy paint is:

Water is dropped into a mixing bowl, cellulose thickener is added under 300-500 rev/min of speed, stir and add dispersion agent after 10 minutes, defoamer, wetting agent, titanium dioxide, disperse 30 minutes under 800-1200 rev/min of speed, sand milling, 50 microns are less than to fineness, then under 300-500 rev/min of speed, elastomeric propylene yogurt liquid is added, antifreezing agent, film coalescence aid, alkali swollen thickener, sterilant, stir 30 minutes to even, proceed to kneader, under agitation slowly, add natural colour sand in batches, inorganic powder, inorganic gel, setting agent, to even, namely described Liquid rock grain is obtained again with the screen filtration required.

Described elastomeric propylene yogurt liquid is a kind of or arbitrary combination of two kinds in pure acrylic acid synthetic emulsion, styrenated acrylic's synthetic emulsion;

Described antifreezing agent is ethylene glycol, propylene glycol a kind of or both arbitrary combination;

Described titanium dioxide is import rutile-type, state's producing rutile a kind of or both arbitrary combination;

Described defoamer, sterilant, dispersion agent, alkali swollen thickener, cellulose thickener are the conventional reagent of aqueous architectural coating, all have merchandise sales;

The grain diameter of described natural colour sand is between 100 microns-1000 microns;

The grain diameter preferable range of described inorganic powder is 1 micron-2000 microns;

Described inorganic gel is one or more the arbitrary combination in silicate, calcium carbonate, magnesium oxide.

Take the present invention of above-mentioned measure, with high molecular synthetic resin emulsion for base-material, the color sand of pure natural and inorganic powder is adopted to be filler, use inorganic gel as linking agent, Liquid rock grain is processed through operations such as dispersion, grinding, granulation, sub-sieve, sizings, there is superpower water-fast, weathering resistance, crack resistence, can combine closely with all kinds of water-based mineral varnish.Liquid rock grain can make the decorative effect of artificial granite paint more true to nature and have the good weathering resistance of lithotome, resistance to acids and bases, and hardness and naturally color and gloss, be used in artificial granite sandy paint, can reach the imitative stone effect that single rifle is colorful.Liquid rock grain prepared by the present invention is special innovative technology manufacture, be the softness that differs in size of 1-12mm and there is elastic irregular sheet molectron, the color of often kind of Liquid rock grain is all made up of natural inorganic element, will never change colour, resistance to fire-retardant, color or shape are all form according to grain color, configuration of surface manufacture in natural grouan, can make the decorative effect nondiscoloration of coating and not affect coating property.
