Abstract

The invention provides a flame-retardant and fire-resistant silicone rubber material as well as a preparation method and application thereof. The flame-retardant and fire-resistant silicone rubber material is prepared from the following raw materials in parts by weight: 50 to 100 parts of organic silicone rubber, 1 to 39 parts of organosiloxane, 20 to 50 parts of a reinforcing filler, 50 to 300 parts of a flame retardant, 90 to 300 parts of a fire-resistant filler and 1 to 19 parts of other auxiliary agents. The flame-retardant and fire-resistant silicone rubber material is good in flame-retardant and fire-resistant performance, easy to produce and process and low in cost.

Description

technical field [0001] The invention relates to the technology in the field of refractory materials, in particular to a flame-retardant refractory silicone rubber material and its preparation method and application. Background technique [0002] At present, various industries at home and abroad pay more and more attention to electric power fire protection and building fire protection. Governments of various countries have also issued many requirements and standards, and the fire resistance and fire protection requirements are getting higher and higher. [0003] For example, the biggest safety point in the electric power industry is the power cable, whether it is power transmission, transmission, transformation, or where power cables and power equipment are densely populated, they are all key points of protection. Doing a good job in power safety protection can greatly eliminate hidden dangers and reduce fire occurrences; it can greatly improve the safety environment of indus...
