Abstract
The invention discloses a formula of a high-performance, low-halogen, environment-friendly and flame-retardant steel wire rope core conveyer belt. The conveyer belt is prepared from raw materials in parts by weight as follows: 60.0 parts of styrene-butadiene rubber, 20.0 parts of butadiene rubber, 20.0 parts of standard rubber, 6.0 parts of indirect zinc oxide, 0.8 parts of an anti-aging agent RD,1.5 parts of an anti-aging agent 4010NA, 1.5 parts of paraffin, 18.0 parts of 70# chlorinated paraffin, 7.0 parts of antimony trioxide (0 level), 8.0 parts of ammonium polyphosphate, 30.0 parts of aflame retardant WX-01, 12.0 parts of a flame retardant WX-02, 15.0 parts of a flame retardant WX-03, 1.2 parts of an accelerant CZ, 0.6 parts of an accelerant DM, 45.0 parts of carbon black N234 and 3.0 parts of sulfur powder. Cover rubber pressed with the formula has no rubber breakage, rubber rotting or rubber scorching phenomena, discharge cover rubber sheets have flat and smooth surfaces, a good foundation is laid for vulcanization of good finished products in a vulcanization process, manual rubber holding is not required, the labor intensity is greatly reduced, and the worker demand is reduced.
Description
technical field [0001] The invention relates to a rubber conveyor belt, in particular to a preparation method of a high-performance low-halogen environment-friendly flame-retardant steel cord conveyor belt. Background technique [0002] Steel cord flame retardant conveyor belt has good flame retardancy, and is widely used in various industries such as coal mines, power plants, and chemicals. Since neoprene contains a large amount of harmful organic substances, the solvent in neoprene is often emitted into the air during use, and the excessively released harmful gas seriously pollutes the environment. In recent years, many measures have been put forward for environmental protection at home and abroad, and many polluting enterprises have even been shut down because of environmental pollution. Therefore, low-carbon environmental protection and personal health have attracted the attention of all walks of life. Safety, environmental protection and energy saving are inevitable tr...
