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.Polymethylmethacrylate in raw material and polycarbonate have different reflectivity, when both are used in combination, can improve reflecting properties, thus improve heat-proof quality.
