▎ 摘  要

NOVELTY - High temperature-resistant halogen-free flame-retardant ceramic refractory silicone foam material comprises component A and component B, where the component A comprises 100 pts. wt. hydroxy silicone oil, 10-30 pts. wt. vinyl silicone oil, 2-8 pts. wt. foaming auxiliary agent, 30- 60 pts. wt. refractory filler, 2.5-10 pts. wt. reinforcing filler, 0.1-2 pts. wt. catalyst. The component B comprises: 30-55 pts. wt. hydroxy silicone oil, 10-30 pts. wt. vinyl silicone oil, 8-15 pts. wt. crosslinking agent, 30-50 pts. wt. refractory filler, 1-10 pts. wt. halogen-free flame retardant 2.5 -7.5 pts. wt. multi-stage composite fluxing agent, and 0.2-1 pts. wt. inhibitor. USE - High temperature-resistant halogen-free flame-retardant ceramic refractory organosilicone foam material. Uses include but are not limited to defense equipment manufacturing, building, packaging, environmental pollution treatment, automobile and electronic industry. ADVANTAGE - The material is high temperature-resistant, halogen-free flame-retardant ceramic refractory organosilicone foam material. It has improved thermal stability, flame retarding smoke inhibiting performance, and fireproof performance of more than 2 hours. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the preparation method of the high temperature-resistant halogen-free flame-retardant ceramic refractory organosilicone foam material comprising preparing A component, specifically comprising: dispersing hydroxy silicone oil, vinyl silicone oil and foaming auxiliary agent uniformly by dispersion machine to obtain the first mixture; adding refractory filler and reinforcing filler to the first mixture for many times, mixing uniformly to obtain the second mixture; adding the catalyst to the second mixture, after pre-mixing, using three-roller grinder to grind and disperse to obtain the A component; preparing component B, specifically comprising dispersing hydroxy silicone oil, vinyl silicone oil and crosslinking agent using dispersion machine, fully mixing uniformly to obtain the third mixture; adding the refractory filler, halogen-free flame retardant and multi-stage composite fluxing agent into the third mixture for many times, mixing uniformly to obtain the fourth mixture; adding the inhibitor to the fourth mixture, after pre-mixing, using three-roller grinder to grind and disperse to obtain the B component; de-foaming the A and B components statically, uniformly mixing according to the mass ratio of 1:1, pouring into the mold for foaming at room temperature, obtaining room temperature foamed organosilicone foam; and adding organosilicone foam in the blowing type oven for heat treatment.
