Abstract

The invention discloses a hydrophilic anti-mildew coating. The hydrophilic anti-mildew coating comprises the following components in parts by weight: 40 parts of bisphenol F epoxy resin, 20 parts of methyl methacrylate, 20 parts of acrylic acid, 6 parts of acrylamide, 7 parts of ammonium sulfate, 4 parts of potassium sulfate, 3 parts of sodium hydroxide, 10 parts of polyvinyl alcohol, 10 parts of filler, 2.2 parts of a curing agent, 1.2 parts of a defoaming agent, 1.5 parts of a flatting agent, 0.5 part of a thickener and 50 parts of deionized water. By the coating, water on the surface of the coating can automatically spread out to form a water film and run off, the hydrophilic property of the paint film is increased and the anti-mildew property is also increased.

Description

A kind of wetting ability mould-repellant coating
Technical field
The present invention relates to coating, particularly wetting ability mould-repellant coating.
Background technology
In daily life, we can often find, the paint film that coating is formed has a large amount of globules, and because the globule is comparatively large, the globule can not evaporate timely, therefore, under the erosion of the globule, can affect the life-span of paint film; In addition, for what need to be undertaken dispelling the heat by the object being coated with paint film, if form a large amount of globules and fail to run off timely on object, then not only can affect the heat dispersion of object, improve radiation energy consumption, and the life-span of paint film can be affected.For being used in outdoor coating, if fungicidal properties is bad, paint film is easy to come off.
Summary of the invention
Sprawl voluntarily to make the water on surface and form moisture film loss, improve the hydrophilicity of paint film, improve fungicidal properties, the invention provides a kind of wetting ability mould-repellant coating.
For achieving the above object, a kind of wetting ability mould-repellant coating, count by weight, be made up of 40 parts of bisphenol F epoxy resins, 20 parts of methyl methacrylates, 20 parts of vinylformic acid, 6 parts of acrylamides, 7 parts of Ammonium Persulfate 98.5s, 4 parts of potassium sulfate, 3 parts of sodium hydroxide, 10 parts of polyvinyl alcohol, 10 parts of fillers, 2.2 parts of solidifying agent, 1.2 parts of defoamers, 1.5 parts of flow agents, 0.5 part of thickening material and 50 parts of deionized waters.
Further, described filler is dicalcium powder, mica, barium sulfate or kaolin.
Further, described solidifying agent is polymeric amide or mphenylenediamine.
Further, described stopper is Resorcinol.
Further, described defoamer is polysiloxane-polyether copolymer, and described flow agent is polydimethylsiloxane, described thickening material be association type gather in the cruel thickening material of ammonia one or both.
The invention has the beneficial effects as follows: for group, group wetting ability size order is-COOM>-CONH2>-COOHGreatT.Grea T.GT-OH, and wherein, M represents atoms metal.Therefore, when polymer molecular chain being introduced organic salt composition, the wetting ability of film will be improved to a certain extent.Owing to adopting methyl methacrylate and the vinylformic acid of aforementioned proportion, then add potassium sulfate, therefore, the good hydrophilic property of the paint film that coating of the present invention is formed, after on paint spay-coating to base material, makes the water of coating surface sprawl voluntarily and forms moisture film loss.Owing to adding polyvinyl alcohol, therefore, fungicidal properties can be improved.
Embodiment
Below in conjunction with embodiment, the present invention is further elaborated.
20% deionized water in formula 50 parts, 40 parts of bisphenol F epoxy resins, 20% methyl methacrylate in 20 parts, 20% vinylformic acid in 20 parts, 20% acrylamide in 6 parts, 20% Ammonium Persulfate 98.5 in 7 parts, 4 parts of potassium sulfate, 10 parts of polyvinyl alcohol, 10 parts of fillers, 2.2 parts of solidifying agent, 1.2 parts of defoamers, 1.5 parts of flow agents, 0.5 part of thickening material are joined in the four-hole boiling flask being equipped with thermometer, agitator arm, constant pressure funnel and reflux condensing tube, warming-in-water, to 80-100 DEG C, reacts 30 min.Then remaining deionized water, vinylformic acid, acrylamide, Ammonium Persulfate 98.5, potassium sulfate are mixed and pour constant pressure funnel into, drip mix monomer by constant pressure funnel to reaction system, 1.8-2.5h drips off.After monomer dropping to be mixed, 50 DEG C of constant temperature 20min times.Add 3 parts of sodium hydroxide (0.5%) solution neutralizations, stir, can obtain and there is certain hydrophilic mould-repellant coating.
Described filler is dicalcium powder, mica, barium sulfate or kaolin.Described solidifying agent is polymeric amide or mphenylenediamine.Described stopper is Resorcinol.Described defoamer is polysiloxane-polyether copolymer, and described flow agent is polydimethylsiloxane, described thickening material be association type gather in the cruel thickening material of ammonia one or both.
For group, group wetting ability size order-COOM>-CONH2>-COOHGreatT.Grea T.GT-OH, wherein, M represents atoms metal.Therefore, when polymer molecular chain being introduced organic salt composition, the wetting ability of film will be improved to a certain extent.Owing to adopting methyl methacrylate and the vinylformic acid of aforementioned proportion, then add potassium sulfate, therefore, the good hydrophilic property of the paint film that coating of the present invention is formed, after on paint spay-coating to base material, makes the water of coating surface sprawl voluntarily and forms moisture film loss.Owing to adding polyvinyl alcohol, therefore, fungicidal properties can be improved.
