preparation example Construction

[0031] In the preparation process of the thermal insulation coating, the weight ratio of the nano-alumina, nano-ceria, gallium-doped zinc oxide, ceric acid yttrium-based inorganic pigment and polyurethane resin is preferably 5-10:5-8:5-8 :2-4:400-500, more preferably 6-9:6-8:5-7:3-4:420-480.

[0032] In the step of obtaining the heat-insulating nanocomposite slurry, the dispersion treatment specifically includes: dispersing at a speed of 300-500 rpm for 5-10 minutes; the ball mill treatment specifically includes: using a ball mill to grind for 20-30 minutes. The surface modification step specifically includes: adding a silane coupling agent drop by drop, wherein the silane coupling agent used in the present invention is preferably the silane coupling agent KH570.

[0033] In the first mixed solution, the weight ratio of ethanol, n-octanol, sodium citrate, polyethylene glycol and deionized water is preferably 30-50:6-15:3-7:3-7:40-60, More preferably, it is 40:10:5:4:50.

[0056] The preparation steps of gallium-doped zinc oxide are as follows:

[0057] Measure 20 parts by weight of zinc sulfate solution (1moL / L), place 10 parts by weight of gallium nitrate solution (0.2moL / L) in a beaker, place the flask on a magnetic stirrer to stir, adjust the temperature to 50°C, weigh Add 2-4 parts by weight of polyethylene glycol into a beaker, add ammonia solution dropwise to the beaker to obtain a precipitate, ultrasonically disperse the white precipitate for 20 minutes, continue the reaction for 20 minutes, stop stirring, and stand for aging at room temperature for 1 hour. Centrifuge the white precipitated product and wash it three times with deionized water and ethanol solution respectively. The precipitate is placed in an oven for 6 hours, and finally calcined in a muffle furnace at 200°C for two hours, and ground to obtain gallium-doped zinc oxide powder.

Abstract

The invention provides a flame-retardant thermal-insulation multilayer film, which comprises a polyethylene glycol terephthalate protective film, an acrylic acid adhesive layer, a polyimide layer, a thermal insulation coating, an organic silicone coating, an organic silicone adhesive layer and an explosion-proof film layer. The thermal insulating coating is formed by thermal insulation paint, which is prepared from raw materials including nano-alumina, nano-cerium dioxide, gallium-doped zinc oxide, an yttrium cerate inorganic pigment, polyurethane resin, a leveling agent and an antifoaming agent. The gallium-doped zinc oxide has excellent optical performance of high reflectivity in the infrared region. Then, the yttrium cerate inorganic pigment contains no heavy metal element, is harmless to the environment, has good high-temperature resistance and physicochemistry stability, and has high reflectivity and chromatic value. Finally, the explosion-proof film layer has good flame retardancy. Experimental results show that use of polyvinyl chloride is avoided and the provided flame-retardant thermal-insulation multilayer film has good flame-retardant effect and high light transmittance.

Description

technical field [0001] The invention relates to the technical field of flame-retardant materials, in particular to a flame-retardant and heat-insulating multilayer film. Background technique [0002] At present, the world's construction industry uses about hundreds of millions of square meters of architectural membranes every year. Because of its low production cost, convenient mounting and replacement during construction, and rich and diverse decorative varieties, no light pollution, it is being used by more and more foreign countries. Realtors and homeowners are bullish. The United States, Germany and other countries adopt the world's most advanced sputtering coating technology, which has a large international market. It is a product of vacuum technology, plasma technology, gas discharge technology, thin film physics, fine chemical industry and other technologies. But the corresponding sputtering coating technology is also relatively expensive. [0003] The development o...
