[0046] B. The preparation of the curing agent is to put the four kinds of raw materials (18)-(21) into the low-speed disperser. After dispersion, the output rough curing agent is produced. The rough curing agent is ground to produce the finished curing agent. tube packaging, ready to use;
[0047] C. Preparation of flame retardant putty. When in use, mix the main agent of the finished product and the finished curing agent in a weight ratio of 100:3-5 to obtain the flame retardant putty of the present invention.
[0048] The flame retardant putty prepared by the method of the present invention.
Embodiment 1
[0051] For the production of the main agent, put 3 parts of nano-montmorillonite as a heat-resistant enhancer and 10 parts of active diluent into a high-speed disperser, and after fully dispersed (5 minutes), a coarse suspension is produced and pumped into the grinder Medium grinding to produce a nano-montmorillonite suspension, then put it into the disperser and add other raw materials three times: the first time: add 70 parts of heat-resistant unsaturated polyester resin, 30 parts of silicone resin, with an interval of 5 minutes, the second time Add 4 parts of anti-settling agent for the second time, with an interval of 5 minutes, add 3 parts of special filler, 5 parts of putty performance modifier, 1 part of flame retardant, 5 parts of low shrinkage additive, and 0.1 part of stabilizer for the third time, as a promotion 0.5 part of dimethyl aniline as agent, 0.5 part of dispersant, 4 parts of titanium dioxide, 5 parts of hollow glass microspheres, 3 parts of drier, 0.5 part ...
example 2
[0056] The production of the main agent, 3 parts of nano-montmorillonite, 15 parts of active diluent, the first time: add 75 parts of heat-resistant unsaturated polyester resin, 25 parts of silicone resin, add 6 parts of anti-settling agent for the second time, and add 6 parts of anti-settling agent for the third time Add 4 parts of special filler, 8 parts of putty performance improver, 3 parts of flame retardant, 6 parts of low shrinkage additive, 0.3 part of stabilizer, 0.8 part of dimethylaniline, 1 part of dispersant, 8 parts of titanium dioxide, hollow glass 5 parts of microbeads, 4 parts of drier, 0.8 parts of molybdenum disulfide, 130 parts of talcum powder;
[0057] The preparation of the curing agent, 6 parts of ketone peroxide, 4 parts of curing agent filler, 1.5 parts of oxacridone blue light red and 0.4 parts of polyvinylpyrrolidone;
[0058] For the preparation of the flame retardant putty, the main agent and the curing agent are mixed and prepared at a ratio of 1...
