Abstract

The invention discloses a nanometer magnesium hydroxide flame retarding silicon rubber composite material and a preparation method thereof. The composite material comprises the following components in parts by weight: 100-120 parts of phenyl silicon rubber, 8-10 parts of diphenyldimethoxysilane, 10-20 parts of nanometer magnesium hydroxide, 5-30 parts of fumed silica, 2-4 parts of cyclotrisilazane, 3-6 parts of montmorillonite, 0.3-0.6 part of chloroform, 3-8 parts of surfactant and 1 part of vulcanizing agent. The composite material provided by the invention has excellent flame retarding property and the mechanical property of the composite material is not reduced at the same time; and the preparation method is simple and easy to operate.

Description

technical field [0001] The invention relates to a flame-retardant silicone rubber, in particular to a flame-retardant silicone rubber composite material modified by nano-magnesium hydroxide and a preparation method thereof. Background technique [0002] The oxygen index of silicone rubber is higher than that of rubber with carbon as the main chain. When burning, the heat release rate is low, the flame propagation speed is slow, and there is no dripping. Moreover, pure silicone rubber hardly generates toxic gases when burning, and it will burn on the surface after burning. The formation of a ceramic carbon silicon layer can prevent the exchange of heat and oxygen and the outward diffusion of internal combustibles to contact with heat and oxygen. Due to the special properties of silicone rubber in terms of flame retardancy and high and low temperature resistance, it has been widely used in aerospace, electronic and electrical, power transmission and mechanical parts an...
