A kind of environmentally friendly flame-retardant neoprene formula

Abstract

The invention relates to an environmentally friendly and flame-retardant neoprene formula. The mass parts of formula components are: 100 chloroprene rubber, 1-4 hexamethylquinoxaline-2,3-dithiocarbamate, 1-2 accelerator DM, 3-10 zinc oxide, 3 magnesium oxide ~10, anti-aging agent 4010NA1~2, paraffin 0.5~2, fast extruded carbon black (N550) 20~40, kaolin 30~40, aluminum hydroxide 30~50, zinc borate 5~15, FR-808A10~20, Tricresyl phosphate 5-15. Through the comparative analysis of the performance of the halogen-containing flame retardant neoprene formula and the halogen-free flame retardant neoprene formula, the performance of the halogen-free flame retardant formula fully meets the standard requirements and can replace the halogen-containing flame retardant neoprene formula . The use of this neoprene formula can meet the requirements for flame retardant use, and the materials used are environmentally friendly and safe for the human body.

Description

technical field [0001] The invention relates to the technical field of rubber formulations, in particular to an environmentally friendly and flame-retardant neoprene formulation. Background technique [0002] With the enhancement of environmental protection awareness, the safety and environmental protection requirements for the rubber materials used are getting higher and higher. At present, the usual chloroprene rubber flame retardant formulations in China mostly use halogen-containing flame retardants such as bromine-containing flame retardants and chlorine-based flame retardants. Fire will produce a large amount of toxic and corrosive hydrogen halide gas, causing secondary hazards, which are usually more serious than those caused by combustion, and seriously endanger people's lives. Contents of the invention [0003] The purpose of the present invention is mainly to solve the problem of toxic and harmful flame retardants in the current formula of flame-retardant neopre...
