Example Embodiment
[0026] Example one:
[0027] A black silicone heat-resistant paint consisting of the following raw materials in parts by weight:
[0028]
[0029] Preparation:
[0030] (1) According to the ratio, first add the black pigment and carbon black dispersant to the solvent for pre-soaking for 48 hours to obtain the modified black pigment;
[0031] (2) Mix and stir the modified black pigment in (1) with silicone resin, filler, anti-settling agent and solvent;
[0032] (3) Put the uniformly mixed materials in (2) into the sand mill for grinding for 20 minutes, so that the particle size of the materials is 28μm;
[0033] (4) Add curing agent to the materials in (3) to mix, and get black silicone heat-resistant paint.
