Problems solved by technology

Traditional halogen flame retardants can achieve a good flame retardant effect, but they will release toxic hydrogen halide gas during combustion, which is harmful to the human body and the environment; and inorganic flame retardant fillers often require a high amount of addition to Meet the flame retardant requirements, but affect the performance of the material
[0004] Organophosphorus flame retardant is a flame retardant with good flame retardant performance. It has dual functions of flame retardant and plasticizing. It can replace halogenated flame retardants and make flame retardant completely halogen-free. Great impact on physical and mechanical properties

Abstract

The invention provides an environmental-friendly flame retardant rubber material and a preparation method thereof. The environment-friendly flame retardant rubber material comprises the following components in part by weight: 100 parts of rubber matrix, 2 to 3 parts of vulcanizing agent, 1 to 1.5 parts of accelerating agent M, 0.2 to 0.4 part of accelerating agent D, 0.2 to 0.8 part of accelerating agent TMTD, 0.5 to 1.5 parts of stearic acid, 3 to 5 parts of zinc oxide, 1 to 2 parts of anti-aging agent A, and 10 to 15 parts of fire retardant. For the environment-friendly flame retardant rubber material prepared by the method, GB528-83, GB / T1689-1998, and GB / T10707 standards are adopted to test the tensile property, abrasion resistance and flame resistance of the rubber. The result shows that the prepared flame retardant rubber has good flame retardancy, relatively good mechanical property and abrasion resistance, and low production cost and easy implementation.

Description

technical field [0001] The invention relates to a flame-retardant rubber material and a preparation method thereof. Background technique [0002] As a polymer material with excellent performance, natural rubber has been widely used in various fields, such as: wires, cables, conveyor belts for mines, hoses, various rubber products used in electronics and electrical industries, as well as automobiles, Rubber products used in airplanes and ships, and rubber sheets used in public places such as hospitals, stations, movie theaters, and train carriages. [0003] The vast majority of rubber products are combustible or combustible, which is a serious disadvantage in their application, so their flame retardancy is of great importance. Traditional halogen flame retardants can achieve a good flame retardant effect, but they will release toxic hydrogen halide gas during combustion, which is harmful to the human body and the environment; and inorganic flame retardant fillers often requi...
