Formula of environment-friendly flame-retardant chloroprene rubber

Abstract

The invention relates to the formula of environment-friendly flame-retardant chloroprene rubber. The flame-retardant chloroprene rubber, according to the formula thereof, comprises the following components by weight part: 100 parts of chloroprene rubber, 1 to 4 parts of hexamethyl-quinoxaline-2,3-dithioformate, 1 to 2 parts of DM as accelerator, 3 to 10 parts of zinc oxide, 3 to 10 parts of magnesium oxide, 1 to 2 parts of 4010NA as anti-ager, 0.5 to 2 parts of paraffin, 20 to 40 parts of FEF (fast-extruding furnace) carbon black (N550), 30 to 40 parts of kaolin, 30 to 50 parts of aluminum hydroxide, 5 to 15 parts of zinc borate, 10 to 20 parts of FR-808A and 5 to 15 parts of tricresyl phosphate. According to the comparative analysis on the performance of the chloroprene formula using halogen-containing flame retardant and the chloroprene rubber formula using halogen-free flame retardant, the performance of the formula using the halogen-free flame retardant in the invention can fully satisfy the requirements of standards, thus substituting for the chloroprene formula using the halogen-containing flame retardant; and based on the chloroprene rubber formula, the invention can meet the requirements of the flame-retardant application, and the materials of the formula are environment friendly and safe for human bodies.

Description

Technical field The invention relates to the technical field of rubber formulations, in particular to an environmentally friendly flame-retardant neoprene formulation. Background technique With the enhancement of environmental protection awareness, the safety and environmental protection requirements of the rubber materials used are getting higher and higher. At present, the usual domestic neoprene flame retardant formulations mostly use halogen-containing flame retardants such as bromine-containing flame retardants and chlorine-based flame retardants. Although the use of such flame retardants can meet good flame retardant effects, once it occurs Fires will produce a large amount of toxic and corrosive hydrogen halide gas, causing secondary hazards. The hazards are usually more serious than the consequences of burning, which seriously endanger people's lives. Summary of the invention The purpose of the present invention is mainly to solve the toxic and harmful problem of flam...
