Abstract

The invention discloses an anti-aging high-flame retardant silicone rubber composite material. The anti-aging high-flame retardant silicone rubber composite material is prepared from the following rawmaterials: silicone rubber, ethylene-propylene-diene monomers, polycarbonate, zinc oxide, stearic acid, sulphur, dicumyl peroxide, iron oxide, titanium dioxide, glass fibres, bromomethyl p-tertiary phenol formaldehyde resin, melamine cyanurate, silicone oil, a silane coupling agent, zinc stearate, an accelerant, an anti-aging agent and a flame retardant; the flame retardant is a mixture of resorcinol (diphenyl phosphate), cucurbituril, magnesium hydroxide and ammonium polyphosphate. The anti-aging high-flame retardant silicone rubber composite material provided by the invention has good heatresistance and aging resistance, and excellent flame retardant property.

Description

technical field [0001] The invention relates to the technical field of silicone rubber, in particular to an aging-resistant and highly flame-retardant silicone rubber composite material. Background technique [0002] Silicone rubber is a semi-inorganic and semi-organic polymer with alternating main chains of Si-O and organic groups in the side chains. It has both the flexibility of organic polymers and the heat resistance of inorganic polymers. It has been widely used in aerospace, national defense, petrochemical, medical and health, machinery manufacturing, electronic appliances, building materials, automobiles, and ships. various fields of the national economy. Although silicone rubber has excellent properties, its flame retardancy as an organic substance is not very good. When used in special fields such as aerospace and national defense and military industry, it has the defects of unsatisfactory flame retardancy and poor aging resistance. its application.
