Abstract

The invention discloses an environmental-protection heatproof flame-retardation silicone rubber. The heatproof flame-retardation silicone rubber comprises the following components: methyl vinyl silicone rubber, carbon black, carboxyethyl phenyl hypophosphorous acid metal salt, melamine cyanurate, zinc borate, a silane coupling agent, zinc stearate, a plasticizer, sulfur powder, a promoter, and anantioxidant. The invention also provides a preparation method of the environmental-protection heatproof flame-retardation silicone rubber. The method comprises the following steps: adding methyl vinylsilicone rubber, carbon black, carboxyethyl phenyl hypophosphorous acid metal salt, melamine cyanurate, zinc borate, the silane coupling agent, the plasticizer, and the antioxidant in a mixing machine and uniformly mixing the raw materials, adding zinc stearate, sulphur and the promoter and uniformly mixing the materials to prepare a mother material, and adding the mother material in a vulcanizerfor sulfuration to prepare the environmental-protection heatproof flame-retardation silicone rubber. The silicon material of the heatproof flame-retardation silicone rubber has the advantages of highoxygen index, no halogen, safety, environmental protection, and wide application prospect.

Description

technical field [0001] The invention relates to the technical field of flame retardancy, in particular to an environmentally friendly heat-resistant flame-retardant silicone rubber and a preparation method thereof. Background technique [0002] Silicone rubber refers to the rubber whose main chain is composed of silicon and oxygen atoms alternately, and there are usually two organic groups attached to the silicon atoms. Ordinary silicone rubber is mainly composed of silicone chains containing methyl groups and a small amount of vinyl groups. The introduction of phenyl groups can improve the high and low temperature resistance of silicone rubber, and the introduction of trifluoropropyl and cyano groups can improve the resistance of silicone rubber. Heat and oil resistance. Silicone rubber has good gas permeability, physiological inertia and other characteristics, and has a wide range of applications. [0003] In recent years, the flame retardant modification of silicone rub...
