Problems solved by technology

[0002] Rubber materials are strategic materials and occupy an important position in the national defense industry. Almost all types of projects are inseparable from rubber products, especially in modern fighters, ships, rockets, etc.; rubber is also a commonly used production The materials of utensils are widely used in daily production, and in the process of use, open flames are often necessary, which will cause the rubber materials to burn during use, which will bring certain safety hazards to production and life. Therefore, it is an urgent problem to provide a rubber material stone that can effectively prevent fire

Abstract

The invention relates to the field of rubber products, and in particular to fire-resistant rubber which is prepared from the following raw materials in parts by weight: 70-80 parts of silicon rubber, 60-70 parts of isoprene rubber, 50-70 parts of fluororubber, 1-5 parts of expanded vermiculite, 15-20 parts of tread rubber powder, 10-20 parts of bentonite, 1-10 parts of asphalt, 1-3 parts of 2-thiol imidazoline, 5-15 parts of coumarone resin, 1-5 parts of methyl methacrylate, 5-10 parts of insoluble sulfur, 1-3 parts of an accelerant, 1-5 parts of a dispersing agent, 1-3 parts of a defoaming agent, 5-10 parts of a wetting agent, 1-5 parts of a penetrant, 5-10 parts of a flame retardant and 5-10 parts of a fire-resistant agent. The fire-resistant rubber prepared according to the formula is good in fire resistance and flame retardancy, has a certain protection function in big fire, and has the advantages of high elasticity, chemical resistance, weather resistance and the like, loss caused by fire can be reduced for people, and the rubber is simple in production process, high in material availability and low in cost.
