Description

A kind of latex outer wall paint and preparation method

Technical field

The present invention relates to paint field, be specifically related to a kind of building coating, can be used for the latex outer wall paint of the decorating outer wall of building such as house, hotel, school, hospital, office, apartment, have that environmental-protecting performance is good, construction is simple, waterproof, the advantage such as pollution-free, nontoxic, tasteless, and have that sticking power, water proof and dust proof are strong, scrubbing resistance, cold-resistantly to freeze, the feature such as water tolerance, preservative property are strong, ventilation property, weathering resistance are strong, mildew-resistant algae-resistant.

Background technology

The major function of exterior wall latex paint is decoration and architecture protection object plane, makes buildings appearance neat and artistic, thus reaches the object of beautifying urban environment, can play the effect of architecture protection beyond the region of objective existence wall simultaneously, extend its work-ing life.The characteristic of exterior wall latex paint: good decorative property: require exterior wall latex paint rich color, select variation, tint retention is good, the long period can keep good decorate properties; Water-tolerant: in an atmosphere, will often be subject to the rainwash people, thus exterior wall latex paint must possess good water resistance to exterior wall long-term exposure; Contamination resistance is good: after the dust in air and other materials stain coating, coating can lose original aesthetic, and thus exterior wall latex paint not easily must be stain or stain rear easy cleaning by these materials; Good weatherability: expose coating in an atmosphere by under the influence and effect of many weather environment factors, the phenomenons such as general coating there will be cracking, peels off, shedding, variable color, make it lose original ornamental and protectiveness.Therefore, can not there is above-mentioned breakoff phenomenon in exterior wall latex paint coating needs, it must possess good weather resistance in the time limit of regulation.Tack is good: exterior wall will bear the interference of various material in air, and therefore the adhesion property of exterior wall latex paint is higher than the requirement of interior wall a lot.

Summary of the invention

The object of the present invention is to provide a kind of building coating, can be used for the latex outer wall paint of the decorating outer wall of building such as house, hotel, school, hospital, office, apartment, have that environmental-protecting performance is good, construction is simple, waterproof, the advantage such as pollution-free, nontoxic, tasteless, and have that sticking power, water proof and dust proof are strong, scrubbing resistance, cold-resistantly to freeze, the feature such as water tolerance, preservative property are strong, ventilation property, weathering resistance are strong, mildew-resistant algae-resistant.

Present invention employs such technical scheme: the material in described latex outer wall paint and weight proportion respectively: 110 parts, water, titanium dioxide 22 parts, talcum powder 23 parts, kaolin 25 parts, water-ground limestone 20 parts, light calcium carbonate 20 parts, defoamer 2.3 parts, dispersion agent 2.5 parts, thickening material 2.8 parts, flow agent 2.2 parts, mould inhibitor 1.8 parts, 2.1 parts, sterilant, 61 parts, vinylformic acid, aqueous polyurethane 58 parts, vinylformic acid organosilicon 65 parts, frostproofer 8 parts, help knot agent 6.9 parts, pH adjusting agent 7.5 parts, nanoparticle 7.3 parts.

The present invention is specifically related to a kind of building coating, can be used for the latex outer wall paint of the decorating outer wall of building such as house, hotel, school, hospital, office, apartment.

This product has that environmental-protecting performance is good, construction is simple, waterproof, the advantage such as pollution-free, nontoxic, tasteless, and have that sticking power, water proof and dust proof are strong, scrubbing resistance, cold-resistantly to freeze, the feature such as water tolerance, preservative property are strong, ventilation property, weathering resistance are strong, mildew-resistant algae-resistant.

Embodiment

Present invention employs such technical scheme: in described latex outer wall paint, material and weight proportion are respectively: 110 parts, water, titanium dioxide 22 parts, talcum powder 23 parts, kaolin 25 parts, water-ground limestone 20 parts, light calcium carbonate 20 parts, defoamer 2.3 parts, dispersion agent 2.5 parts, thickening material 2.8 parts, flow agent 2.2 parts, mould inhibitor 1.8 parts, 2.1 parts, sterilant, 61 parts, vinylformic acid, aqueous polyurethane 58 parts, vinylformic acid organosilicon 65 parts, frostproofer 8 parts, help knot agent 6.9 parts, pH adjusting agent 7.5 parts, nanoparticle 7.3 parts.

Its preparation method is following steps:

Step one), in high speed dispersor, add water, defoamer, dispersion agent, thickening material, flow agent, abundant blending dispersion evenly after add pH adjusting agent, adjust ph is 10.9 for subsequent use;
