Abstract
The invention discloses an ageing and heat resistant wall coating and a preparation method thereof. The ageing and heat resistant wall coating comprises, by weight, 15-18 parts of a furfural resin, 3-4 parts of alumina, 16-19 parts of a bisphenol A type epoxy resin, 3-6 parts of polytetrafluoroethylene, 4-7 parts of polyvinylpyrrolidone, 2-4 parts of methyl ethyl ketone, 3-5 parts of butyraldehyde and 16-18 parts of n-propanol. The preparation method of the coating comprises a stirring operation, a heating operation, a mixing operation, a crushing operation and the like, and the coating prepared in the invention has good ageing and heat resistances.
Description
Technical field
The present invention relates to a kind of coating for wall surface and preparation method thereof, particularly relate to a kind of ageing-resistant heat-resisting coating for wall surface and preparation method thereof.
Background technology
The ageing-resistant performance of coating refers to coating impact on the performance of coating when accepting daylight and irradiate for a long time.Aging resistance is poor, coating is after long-time use, the color and luster of coating has large variation, reduced the aesthetic measure of coating, by system component and proportioning are adjusted, can effectively improve the ageing-resistant degree of coating, the wherein kind of concrete composition and the selection of ratio, is a comparatively complicated problem.In addition, in high temperature area, the resistance toheat of coating is had to higher requirement, therefore also need to possess good resistance toheat.
Summary of the invention
The technical problem solving: the conventional problem that coating for wall surface is ageing-resistant, resistance toheat is poor.
Technical scheme: the invention discloses a kind of ageing-resistant heat-resisting coating for wall surface, ageing-resistant heat-resisting coating for wall surface is comprised of according to weight ratio following composition: furfuryl resin is that 15～18 parts, aluminum oxide are that 3～4 parts, bisphenol A type epoxy resin are that 16～19 parts, tetrafluoroethylene are that 3～6 parts, polyvinylpyrrolidone are that 4～7 parts, methyl ethyl ketone are that 2～4 parts, butyraldehyde are that 3～5 parts, n-propyl alcohol are 16～18 parts.
Preparation method's step of ageing-resistant heat-resisting coating for wall surface is as follows: (1) gets furfuryl resin is that 15～18 parts, bisphenol A type epoxy resin are that 16～19 parts, tetrafluoroethylene are that 3～6 parts, polyvinylpyrrolidone are that 4～7 parts, methyl ethyl ketone are 2～4 parts, and each composition is put into after tank body and mixed under room temperature; (2) tank body temperature is heightened to 50 ℃, adding wherein butyraldehyde is that 3～5 parts, n-propyl alcohol are 16～18 parts, stirs; (3) by alumina lap to order number, being 400 to 500 orders, is that 400 to 500 object alumina powders are 3～4 parts to adding order number in tank body; (4) be cooled to room temperature after stirring.
Beneficial effect: the coating for wall surface of preparation is 350nm at ultraviolet wavelength, irradiation time is 400 to 450h, coating, without performance and appearance change, heats 80h unchanged at 350 ℃ to 400 ℃.
