Problems solved by technology

Organic fireproof blockage will volatilize toxic gas in case of fire; while fireproof plaster is non-toxic, but it forms a hard block after curing, has no stretching and compression elasticity, and cannot compensate for mechanical displacement caused by mechanical pipeline vibration and building settlement , and pipes and cables and other wall-penetrating objects are extremely inconvenient in maintenance and replacement; and the traditional silicone rubber has poor flame retardancy and cannot adapt to workplaces with high fire protection requirements such as power plants, nuclear power plants, and petrochemical oil and gas pipelines.

Abstract

The invention discloses fireproof silicone rubber and a preparation method thereof. The fireproof silicone rubber is formed by mixing A component and B component according to the volume ratio of 1: 1 and solidifying the mixture under the temperature ranging from 15 DEG C to 40 DEG C, wherein the A component is composed of organic silicon resin, hydroxyl silicone oil, quartz sand, catalyst, filler, fire retardant and carbon black powder in certain proportion, and the B component is composed of organic silicon resin, hydrosilicone oil, quartz sand and filler in certain proportion. The fireproof silicone rubber has the advantages of being good in inflaming retarding performance, good in mechanical performance, not capable of producing toxic gas in fire and being capable of being widely used in plugging structures with higher fireproof and mechanical requirement, such as mechanical pipelines and cables.

Description

technical field [0001] The invention relates to a fireproof silicone rubber and a preparation method thereof, belonging to the technical field of polymer fireproof materials. Background technique [0002] Most of the existing fireproofing blockages use organic fireproofing materials and fireproofing plaster. Organic fireproof blockage will volatilize toxic gas in case of fire; while fireproof plaster is non-toxic, but it forms a hard block after curing, has no stretching and compression elasticity, and cannot compensate for mechanical displacement caused by mechanical pipeline vibration and building settlement , and pipes and cables and other wall-penetrating objects are extremely inconvenient in maintenance and replacement; and traditional silicone rubber has poor flame retardancy and cannot be adapted to workplaces with high fire protection requirements such as power plants, nuclear power plants, and petrochemical oil and gas pipelines. Contents of the invention [0003...
