Ceramic fire-resistant flame-retardant silicone rubber as well as preparation method and use method thereof

Abstract

The invention relates to the technical field of silicone rubber, in particular to ceramic fire-resistant flame-retardant silicone rubber as well as a preparation method and a use method thereof. The silicone rubber is prepared from the following raw materials in parts by weight: 8-12 parts of hydroxyl-terminated polydimethylsiloxane, 95-105 parts of first methyl vinyl silicone rubber, 30-45 partsof fumed silica, 1-3 parts of methoxy silicone oil, 0.1-0.3 part of a silane coupling agent, 0-0.1 part of benzotriazole, 0.01-0.3 part of a release agent, 50-70 parts of a filler, 60-140 parts of second methyl vinyl silicone rubber, 1-3 parts of vinyl trimethoxy silicon, 0.1-2 parts of hexamethyldisilazane, 0.1-0.3 part of zinc stearate, 0.5-1.5 parts of a hydrolysis agent, 200-240 parts of a flame retardant, 10-30 parts of zinc oxide and 10-30 parts of calcium carbonate. The ceramic fire-resistant flame-retardant silicone rubber has good fire-resistant and flame-retardant performance and excellent comprehensive performance, and the preparation method of the ceramic fire-resistant flame-retardant silicone rubber is simple.

Description

technical field [0001] The invention relates to the technical field of silicone rubber, in particular to a vitrified fire-resistant and flame-retardant silicone rubber, a preparation method and a use method thereof. Background technique [0002] Because of its good aging resistance and stability, silicone rubber has a wide range of applications, and with the continuous improvement of the level of industrialization, people's requirements for silicone rubber are also getting higher and higher. For industrial production, commonly used silicone rubber itself is not Flame retardant is not fire-resistant. In fire accidents, wires and cables are not fire-resistant and easy to burn in case of fire. This field lacks a fire-resistant silicone rubber. It is required not only to have the excellent characteristics of rubber during normal use, but also to have better properties. Flame retardant and fire-resistant properties, the products made by using it can play a certain protective role...

It is required not only to have the excellent characteristics of rubber during normal use, but also to have better properties. Flame retardant and fire-resistant properties, the products made by using it can play a certain protective role in the fire, can reduce the loss caused to people in the fire, and reduce the harm
