Flame-retardant styrene butadiene rubber

Abstract

The invention discloses a flame-retardant styrene butadiene rubber, which includes the following raw materials by weight: 100 parts of styrene butadiene rubber-1500, 1 part of stearic acid, 3 parts of sulfur, 5 parts of zinc oxide, 1 part of an accelerator NOBS, 1 part of an antioxidant 4010NA, 10 parts of carbon black N330, 40 parts of white carbon black, 80 parts of hydrotalcite, 10 parts of microencapsulated red phosphorus and 10 parts of tricresyl phosphate. The flame retardant styrene butadiene rubber provided by the invention has the advantages of little mechanical performance loss and obvious flame retardant effect, meets the requirements for industrial production and daily use.

Description

[0001] technical field [0002] The invention relates to a styrene-butadiene rubber, in particular to a flame-retardant styrene-butadiene rubber. [0003] Background technique [0004] With the enhancement of social awareness of fire prevention, more and more occasions require the use of rubber products to be flame retardant, such as conveyor belts in coal mines, air ducts, cables; flooring materials used in the construction field, door and window sealing strips, household Electrical appliances; many rubber products used in ships, etc. The currently used flame retardants generally have defects such as low flame retardant efficiency, single function, and poor compatibility with the rubber matrix. [0005] Contents of the invention [0006] The purpose of the present invention is to provide a flame-retardant styrene-butadiene rubber with very small loss of mechanical properties and obvious flame-retardant effect, which meets the requirements of industrial production and d...
