Embodiment 1
[0015] Formula: 15% PVDF fluorocarbon resin, 10% epoxy resin, 5% silane coupling agent, 31.3% isophorone, 8% propylene glycol methyl ether acetate, 25% ethyl acetate, 0.5 % fluorocarbon modified defoamer, 2% nano-siloxane modified fumed silica, 2% modified matting powder, 1% nano-medicine stone particles, 0.2% alkali-swellable thickener.
[0016] Preparation:
[0017] a. Mix the nano-siloxane-modified fumed silica, silane coupling agent, and ethyl acetate in the above mass fractions evenly, and stir at 50° C. for 30 minutes. Then sieve with a sieve of 80-100 mesh, take the mixture whose particle diameter is smaller than the sieve diameter, and obtain the modified nano-siloxane modified fumed silica.
[0018] b, the modified nano-siloxane modified fumed silica prepared in step a, PVDF fluorocarbon resin, epoxy resin, isophorone, propylene glycol methyl ether acetate, nano wheat The rice stone particles are mixed and put into a stirring tank, the rotating speed of the stirring...
