Embodiment 1
[0031] A preparation method for heat-insulating and anti-ultraviolet glass film, said preparation method comprising the following steps:
[0032] S1: Disperse the salicylate compound and PET resin in the aqueous solution of ethanol, stir evenly, form a coating solution, and set aside;
[0033] S2: put the metal oxide solid particles in the fluidized state in the fluidized bed reactor, close the inlet and outlet valves of the fluidized bed reactor, and pass into the supercritical carbon dioxide fluid entrained with the coating liquid prepared in the step S1, In a supercritical state, stir and mix for 1 min, reduce the outlet pressure, and coat the salicylate compound and PET resin on the surface of the metal oxide solid particles. After filtering, washing and drying, the modified metal oxide solid particles are obtained. ;
[0034] S3: Stir and mix the modified metal oxide solid particles, coupling agent, additives, and PET prepared in step S2 to form a casting solution, injec...
Embodiment 2
[0044] A preparation method for heat-insulating and anti-ultraviolet glass film, said preparation method comprising the following steps:
[0045]S1: Disperse the salicylate compound and PET resin in the aqueous solution of ethanol, stir evenly, form a coating solution, and set aside;
[0046] S2: put the metal oxide solid particles in the fluidized state in the fluidized bed reactor, close the inlet and outlet valves of the fluidized bed reactor, and pass into the supercritical carbon dioxide fluid entrained with the coating liquid prepared in the step S1, In a supercritical state, stir and mix for 4 minutes, reduce the outlet pressure, and coat the salicylate compound and PET resin on the surface of the metal oxide solid particles. After filtering, washing and drying, the modified metal oxide solid particles are obtained. ;
[0047] S3: Stir and mix the modified metal oxide solid particles, coupling agent, additives and PET prepared in step S2 to form a casting solution, inj...
Embodiment 3
[0057] A preparation method for heat-insulating and anti-ultraviolet glass film, said preparation method comprising the following steps:
[0058] S1: Disperse the salicylate compound and PET resin in the aqueous solution of ethanol, stir evenly, form a coating solution, and set aside;
[0059] S2: put the metal oxide solid particles in the fluidized state in the fluidized bed reactor, close the inlet and outlet valves of the fluidized bed reactor, and pass into the supercritical carbon dioxide fluid entrained with the coating liquid prepared in the step S1, In a supercritical state, stir and mix for 8 minutes, reduce the outlet pressure, and coat the salicylate compound and PET resin on the surface of the metal oxide solid particles. After filtering, washing and drying, the modified metal oxide solid particles are obtained. ;
[0060] S3: Stir and mix the modified metal oxide solid particles, coupling agent, additives and PET prepared in step S2 to form a casting solution, in...
