Problems solved by technology

[0002] At present, limestone, as a natural stone, is more and more widely used in high-end office buildings, villas and other high-end building exterior walls; and limestone coating is a new high-end new stone-like architectural coating emerging in the market, and its coating film has natural The texture of limestone is highly decorative, and the degree of simulation can reach more than 90%. It is mainly used to imitate the decorative effect of special-shaped textured stones such as German beige and limestone; Or other dark and damp building surfaces, molluscs such as slugs and snails crawl on the surface of the limestone coating, and sometimes mold spots will appear due to the cellulose ether in the limestone coating being decomposed by bacteria , has seriously affected the decorative effect and market promotion and application of limestone coatings

Embodiment 1

[0017] Embodiment 1: a kind of anti-insect mildew-proof limestone paint preparation method, it comprises limestone bottom sand and overcoat varnish, when using, earlier besmear limestone bottom sand on wall surface to form bottom sand coating, then coat bottom sand coating surface Apply a top varnish to create a limestone composite coating. The formula of limestone bottom sand consists of the following components in parts by mass: 30 parts of water; 0.4 parts of cellulose ether; 0.8 parts of pH regulator; 18 parts of rutile titanium dioxide; 22 parts of filler; 21.4 parts of acid salt; 4 parts of styrene-acrylic silicon high polymer emulsion; 0.4 part of defoamer; Ether; after complete dissolution, add PH regulator, rutile titanium dioxide and filler, and disperse it to a fineness below 50 μm at high speed; then add modified inorganic polymer silicate and styrene-acrylic silicon polymer emulsion , anti-foaming agent and anti-insect factor, after mixing evenly, filter, and fin...

Embodiment 2

[0021] Embodiment 2, the preparation process of embodiment 2 is roughly the same as embodiment 1, and its difference is, the prescription of limestone bottom sand is made up of following composition by mass parts: 20 parts of water; 0.1 part of cellulose ether; PH regulator 0.5 parts; 15 parts of rutile titanium dioxide; 15 parts of filler; 20 parts of modified inorganic polymer silicate; 3 parts of styrene-acrylic silicon polymer emulsion; 0.3 parts of defoamer; The formula of the finish varnish consists of the following components in parts by mass: 60 parts of fluorine-modified polymer emulsion; 3 parts of film-forming agent; 0.3 parts of defoamer; 20 parts of water; 0.5 parts of propylene glycol; part; 0.3 part of thickener; it can reach the effect of embodiment 1 equally.

Embodiment 3

[0022] Embodiment 3, the preparation process of embodiment 3 is roughly the same as embodiment 1, and its difference is, the prescription of limestone bottom sand is made up of following composition by mass parts: 30 parts of water; 0.4 part of cellulose ether; PH regulator 1.5 parts; 25 parts of rutile titanium dioxide; 25 parts of filler; 30 parts of modified inorganic polymer silicate; 6 parts of styrene-acrylic silicon polymer emulsion; 0.5 parts of defoamer; The formula of the finish varnish consists of the following components in parts by mass: 70 parts of fluorine-modified polymer emulsion; 4 parts of film-forming agent; 0.5 parts of defoamer; 30 parts of water; 1 part of propylene glycol; part; 0.5 part of thickener; it can reach the effect of embodiment 1 equally.

Abstract

The invention discloses a method for preparing an insect-proof and mildew-proof limestone coating, which comprises a limestone base sand and an overcoat varnish. The limestone base sand is composed of water, cellulose ether, a pH regulator, rutile type titanium dioxide, fillers, Inorganic high molecular silicate, styrene-acrylic silicon high polymer emulsion, defoamer and anti-insect factor; finish varnish is composed of fluorine-modified high polymer emulsion, film-forming agent, defoamer, water, propylene glycol, anti-insect factor It is composed of adhesion aid and thickener; after preparation, the base sand layer is formed by first applying limestone base sand on the wall surface, and then coating the finish varnish on the base sand layer to form a limestone composite coating. It is not easy to breed bacteria, makes it difficult for molluscs to attach, and is environmentally friendly and harmless.

Description

technical field [0001] The invention belongs to the technical field of limestone coatings, in particular to a method for preparing an insect-proof and mildew-proof limestone coating. Background technique [0002] At present, limestone, as a natural stone, is more and more widely used in high-end office buildings, villas and other high-end building exterior walls; and limestone coating is a new high-end new stone-like architectural coating emerging in the market, and its coating film has natural The texture of limestone is highly decorative, and the degree of simulation can reach more than 90%. It is mainly used to imitate the decorative effect of special-shaped textured stones such as German beige and limestone; Or other dark and damp building surfaces, molluscs such as slugs and snails crawl on the surface of the limestone coating, and sometimes mold spots will appear due to the cellulose ether in the limestone coating being decomposed by bacteria , has had a strong impact...
