Abstract
The invention discloses paint for an external wall and belongs to the technical field of building paint. The paint is prepared from, by weight, 20-25 parts of acrylate emulsion, 10-20 parts of polysiloxane, 12-18 parts of talcum powder, 5-12 parts of pigments, 1-5 parts of coalescing agents, 0.5-1 part of mildew preventive, 0.5-1 part of dispersing agent, 0.3-0.8 part of viscosity stabilizer and 25-40 parts of water. The paint is mainly used for the external wall and has the advantages of being good in weather fastness and long in service life.
Description
Technical field
The present invention relates to a kind of coating, particularly relate to a kind of exterior wall coating, belong to building coating technical field.
Background technology
The coating that China's external wall uses is mainly emulsion paint, and its filmogen is polymer emulsion.Emulsion for exterior wall has benzene emulsion, pure-acrylic emulsion, organosilicon crylic acid latex, fluorine carbon emulsion etc., no matter be benzene emulsion, pure-acrylic emulsion, organosilicon crylic acid latex or fluorine carbon emulsion, to make on emulsion paint after wall, through the outdoor aging of 50 to ten years, its performance all has obvious decline, and main manifestations is coating dry linting, even comes off.On the other hand, because filmogen is for having certain hydrophilic organic polymer, under certain temperature, humidity environment, has mould algae grow.
Publication number is the Chinese invention patent that CN102876150A name is called " anti-graffiti water-borne coatings of the anti-stick subsides of a kind of high durable and preparation method thereof ", disclosing this coating is two-component coating, the weight ratio of component A and B component is 4: 1, component A is by hydroxyl fluorine carbon emulsion, anti-graffiti resin, defoamer, wetting agent, water forms, described B component is hydrophilic isocyanate curing agent, (3) water and anti-graffiti resin is added to hydroxyl fluorine carbon emulsion, then defoamer is added, wetting agent, finally add isocyanate curing agent, namely the anti-graffiti water-borne coatings of the anti-stick subsides of high durable is obtained.The dispersiveness of this coating is not high enough, and weathering resistance also need to improve.
Summary of the invention
The present invention is intended to solve in prior art, the weathering resistance of exterior wall coating is bad, along with the prolongation of working life, exterior wall mildew, painting color change greatly, affects the problem of body of wall outward appearance, a kind of new exterior wall coating is proposed, by selection and the specific proportioning of raw material, make coating of the present invention be particularly useful for outdoor, there is the advantage that weathering resistance is high, duration of service is long.
In order to realize foregoing invention object, technical scheme of the present invention is as follows:
A kind of exterior wall coating, is characterized in that: comprise following raw material by weight: acrylic ester emulsion 20 ~ 25 parts, organopolysiloxane 10 ~ 20 parts, talcum powder 12 ~ 18 parts, pigment 5 ~ 12 parts, film coalescence aid 1 ~ 5 part, mould inhibitor 0.5 ~ 1 part, dispersion agent 0.5 ~ 1 part, viscosity stabilizer 0.3 ~ 0.8 part, 25 ~ 40 parts, water.
Further preferably, described coating comprises: acrylic ester emulsion 22 ~ 25 parts, organopolysiloxane 15 ~ 18 parts, talcum powder 13 ~ 16 parts, pigment 8 ~ 10 parts, film coalescence aid 2 ~ 4 parts, mould inhibitor 0.6 ~ 0.8 part, dispersion agent 0.6 ~ 0.8 part, viscosity stabilizer 0.4 ~ 0.6 part, 28 ~ 35 parts, water.
In above-mentioned composition, described pigment is mineral dye, and the weathering resistance of mineral dye is higher, as white pigment titanium dioxide, red pigment titanium chrome red, black pigment carbon black, is all the good mineral dye of weathering resistance.
Described film coalescence aid is at least one in propylene glycol, diethylene glycol monomethyl ether, propandiol butyl ether, methoxybutanol.
Described dispersion agent is polyoxyethylene alkyl phenyl ether.
Described viscosity stabilizer is hydrophilic alkyl or alkoxylated amines mixture aqueous solution.
Beneficial effect of the present invention:
The organopolysiloxane added in the present invention has good hydrophobic nature, in exterior coating, can prevent rainwater from adhering on the wall, cause the problem that body of wall is moist and mouldy; The present invention is also by adding mould inhibitor, and what ensure further outside body of wall is attractive in appearance, prevents mildew.The present invention is by rational material choice and specific proportioning, and various composition is mutually coordinated, coordinated, and improves the weathering resistance of coating, extends coating working life.
