Abstract

The invention discloses a preparation method of strong-self-extinguishment, low-smoke and flame-retarding silicon rubber. A formula comprises the following components in parts by mass: 100 parts of mixed silicon rubber, 0.1 to 10 parts of organic peroxide, 0.01 to 1 part of benzotriazole, 0.5 to 30 parts of nano TiO2 and 10 to 120 parts of pre-treated aluminum hydroxide; wherein a platinum elementin the platinum raw material is 10 to 100ppm. Compared with the prior art, the preparation method has the advantages of simple preparation technology, wide universality, high flame-retarding performance, flame-retarding grade V0 (0.8mm), no halogen and environmental friendliness and the like. According to the preparation method disclosed by the invention, the TiO2 and Pt are cooperated and the flame-retarding performance of the silicon rubber can be improved.

Description

technical field [0001] The invention relates to the technical field of flame-retardant rubber, in particular to a preparation method of strong self-extinguishing low-smoke flame-retardant silicone rubber. Background technique [0002] There is a constant desire and ongoing search for flame retardant materials because fire is so destructive and people are eager to use flame retardant materials to protect themselves and their property from damage. Electronic equipment can easily lead to fire, so it is necessary to keep electronic equipment under protection as much as possible, especially on airplanes or boats, where the consequences of a fire caused by electronic equipment or wires on these places will be catastrophic. Because of these potential hazards, the need for flame retardant materials has arisen. With the development of electronics and electric power fields, electronic devices and integrated circuits tend to be denser and miniaturized. To ensure the safe and stable op...
