[0046] The present invention provides a preparation method of the grass green thermal resistance material described in the above technical scheme, which includes the following steps:
[0047] Mix epoxy resin, pigments and fillers with part of the diluent to obtain the first slurry;
[0048] Mixing the first slurry with the grass green colored filler and the film-forming assistant to obtain the second slurry;
[0049] The second slurry is mixed with a polyamide curing agent and the remaining diluent to obtain a grass green thermal resistance material.
[0050] In the present invention, epoxy resin, pigments and fillers are mixed with part of the diluent to obtain the first slurry. In the present invention, the mixing of the epoxy resin, pigments and fillers and part of the diluent is preferably to mix the epoxy resin with the pigments and fillers, stir at 50 to 70 rpm for 2 to 4 minutes, and then add part of the diluent to the resulting mixture , Stir at 50~70rpm for 3~5min to obtain ...
Embodiment 1
[0056] In parts by weight, 11 parts of diatomaceous earth, 27.1 parts of rutile titanium dioxide and 23 parts of E-51 epoxy resin were mixed, stirred at 60 rpm for 3 minutes, and then 10 parts of acetone were added and stirred at 60 rpm for 4 minutes to obtain the first A slurry
[0057] Add 6.5 parts of iron oxide green to the first slurry, stir at 60rpm until the color is uniform; then add 0.6 parts of film-forming aids (the film-forming aids include tributyl phosphate, acrylate and TEGO Dispers 740W Wetting and dispersing agent, the mass ratio of the tributyl phosphate, acrylate and TEGO Dispers 740W wetting and dispersing agent is 2:3:3), stirred at 60 rpm for 3 minutes to obtain a second slurry;
[0058] Add 9 parts of 650 polyamide curing agent to the second slurry, stir at 60 rpm for 5 minutes, then add 13 parts of acetone, and stir at 60 rpm for 4 minutes to obtain a grass green thermal resistance material.
Embodiment 2
[0060] In parts by weight, 9 parts of diatomaceous earth, 26 parts of rutile titanium dioxide and 26 parts of E-51 epoxy resin were mixed, stirred at 60 rpm for 3 minutes, and then 11 parts of acetone were added and stirred at 60 rpm for 4 minutes to obtain the first A slurry
[0061] Add 6.8 parts of iron oxide green to the first slurry, stir at 60 rpm until the color is uniform; then add 0.6 parts of film-forming aids (the film-forming aids include tributyl phosphate, acrylate and TEGO Dispers 740W Wetting and dispersing agent, the mass ratio of the tributyl phosphate, acrylate and TEGO Dispers 740W wetting and dispersing agent is 2:3:3), stirred at 60 rpm for 3 minutes to obtain a second slurry;
[0062] Add 10 parts of 650 polyamide curing agent to the second slurry, stir at 60 rpm for 5 minutes, then add 11 parts of acetone, and stir at 60 rpm for 4 minutes to obtain a grass green thermal resistance material.
