Ethylene-propylene-diene monomer flame-retardant rubber and production method thereof

Abstract

The invention provides ethylene-propylene-diene monomer flame-retardant rubber and a production method thereof. The ethylene-propylene-diene monomer flame-retardant rubber comprises an ethylene-propylene-diene monomer, a reinforcing filler, encapsulated red phosphorous, phenolic resin, an activator, a lubricant, sulfur, an accelerator and an antiager. The production method comprises premixing, internal mixing, open milling, molding and vulcanization. The ethylene-propylene-diene monomer flame-retardant rubber and the production method thereof solve the technical problem that the existing flame-retardant rubber has poor tensile properties, large cigarette toxicity and a high price.

Description

technical field [0001] The invention relates to the field of flame-retardant rubber, in particular to a EPDM flame-retardant rubber and a production method thereof. Background technique [0002] The existing EPDM flame-retardant rubbers are generally divided into two categories. One type uses inorganic flame retardants Al(OH)3 and Mg(OH)2 as the main flame retardant, and zinc borate as the smoke suppressant. It is characterized by environmental protection, halogen-free and low price. The other type uses organic flame retardants as the main body of flame retardants, including halogen flame retardants, phosphorus flame retardants and nitrogen flame retardants. Among them, halogen flame retardants are the most widely used flame retardants, especially brominated flame retardants, which are widely used by manufacturers. [0003] However, the use of inorganic flame retardants requires the addition of a large amount of inorganic components, which will affect the physical propert...

AI Technical Summary

Problems solved by technology

[0003] However, the use of inorganic flame retardants requires the addition of a large amount of inorganic components, which will affect the physical properties of the rubber compound, especially the tensile properties;

[0004] The addition of halogen flame retardant is small, and the flame retardant effect is good, but the smoke toxicity is relatively high, and it will produce toxic gases containing halogen when burning;

[0005] The EPDM flame retardant rubber compound containing phosphorus flame retardant and nitrogen flame retardant has the problems of large addition amount, high price, high smoke density and general flame retardant effect.
