Description
Technical field
The present invention relates to coating, particularly wetting ability thermal insulating 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.In addition, coating is also more and more extensive in the application in heat insulation.
Summary of the invention
Sprawl voluntarily to make the water on surface and form moisture film loss, improve the hydrophilicity of paint film, improve the heat-proof quality of paint film, the invention provides a kind of wetting ability thermal insulating coating.
For achieving the above object, a kind of wetting ability thermal insulating coating, count by weight, be made up of 30-40 part bisphenol F epoxy resin, 10-20 part methyl methacrylate, 15-25 part vinylformic acid, 5-10 part acrylamide, 5-10 part Ammonium Persulfate 98.5,3-5 part potassium sulfate, 20-25 part ceramic fine bead, 3-5 part glass fibre, 2-4 part sodium hydroxide, 10-15 part filler, 2-3 part solidifying agent, 0.5-1 part stopper, 0.5-0.9 part defoamer, 0.3-0.8 part flow agent, 0.3-0.5 part thickening material and 30-50 part deionized water; Wherein, the internal diameter of ceramic microsphere is less than 1 μm, and unit weight should be less than 100kg/m
3.
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 present invention employs special ceramic microsphere as basic raw material, and under the effect of glass fibre, this just makes the hole diameter in material very little, air molecule in pore then loses free-pouring ability, but be relatively attached on air vent wall, be at this moment equivalent to be in material be similar to vacuum state.Ceramic microsphere makes material internal contain extremely many transmitting interfaces and microscopic scatterers simultaneously, and reflection and scattered radiation heat, therefore, the heat-proof quality of the paint film that this coating is formed is good.
