Selectivity light-transmitting and heat-insulating coating and preparing method thereof

Abstract

The invention discloses a selectivity light-transmitting and heat-insulating coating and a preparing method thereof. The coating comprises, by mass, 10 parts to 20 parts of methyl methacrylate, 10 parts to 20 parts of vinyl benzene, 1 part to 4 parts of acrylic resin, 3 parts to 8 parts of cellulose acetate butyrate, 1 part to 6 parts of trimethylolpropane tris-acrylate, 3 parts to 8 parts of nitrous acid diisopropylamine, 2 parts to 6 parts of sodium benzoate, 8 parts to 15 parts of polyhydric alcohol, 2 parts to 5 parts of polyvinyl pyrrolidone, 2 parts to 5 parts of ethoxyquin, 3 parts to 8 parts of amino silicon oil, 2 parts to 6 parts of chlorinated paraffin, 1 part to 5 parts of dibutyltin dilaurate, 1 part to 3 parts of maleic anhydride, 2 parts to 5 parts of 1h-benzotriazole, 2 parts to 5 parts of curing agents, 3 parts to 6 parts of light stabilizers, 4 parts to 8 parts of surface active agents and 1 part to 5 parts of dispersing agents. The good effect can be achieved on preventing solar radiation, so that the proper room temperature is kept indoors.

Description

technical field [0001] The invention belongs to the field of coatings, and in particular relates to a selective light-transmitting heat-insulating coating and a preparation method thereof. Background technique [0002] Among the four enclosure components of doors, windows, walls, roof, and ground that affect building energy consumption, doors and windows have the worst thermal insulation performance, which is one of the important factors affecting indoor thermal environment comfort and building energy consumption. The ratio of glass to window area varies depending on the window frame material, but with the widespread use of glass curtain walls in public buildings and indoor large-area floor-to-ceiling windows in residential buildings, the glass area to window area is becoming larger and larger, The thermal performance of glass affects the thermal performance of the entire window to a large extent, and has a great impact on the comfort of the indoor human body.
