Problems solved by technology

[0005] Pneumatic rubber tires are generally composed of rubber and skeleton materials, but rubber is a material that is extremely flammable in the air. For vehicles that have been operating at high temperatures and close to fire sources for a long time, tires are prone to fire. Phenomena, leaving great hidden dangers to life and property safety
The traditional solution is to use the high-efficiency flame retardant decabromodiphenyl ether in the formula as a flame retardant in the tire formula, but because the EU believes that decabromodiphenyl ether is harmful to the human body, it prohibits the use of decabromodiphenyl ether in tires, As a result, the tire industry has gradually banned the use of decabromodiphenyl ether in tire formulations

Abstract

The invention discloses a flame retardant rubber composition and application thereof. The flame retardant rubber composition does not contain decabromodiphenyl ether, is superior in flame retardancy, and is prepared from natural rubber, 2,2',3,3',4,4',5,5',6,6'-decabromobibenzyl, antimonous oxide, red phosphorus and an assistant. Through the synergistic effect of 2,2',3,3',4,4',5,5',6,6'-decabromobibenzyl, antimonous oxide and red phosphorus, the flame retardancy of a tire sizing material in a formula is greatly improved, so that the prepared rubber does not burn easily and self-extinguishes in case of open fire; the invention further provides the application of the flame retardant rubber composition in the field of tire preparation.

Description

technical field [0001] The invention relates to the field of rubber preparation, in particular to a flame-retardant rubber composition and its application. Background technique [0002] The development of the automotive industry has benefited from substantial advances in the technology of the individual components themselves. As an important part of automobiles, tires have a direct impact on the progress of the automobile industry. [0003] Tires are often used under complex and harsh conditions, and they are subjected to various deformations, loads, forces, and high and low temperature effects during driving, so they must have high load-bearing performance, traction performance, and cushioning performance. [0004] Half of the world's rubber consumption is used for tire production, which shows the ability of tires to consume rubber. However, rubber is flammable. In the complex environment of tires, the flame retardancy of rubber is particularly important. [0005] Pneuma...
