Abstract

The invention discloses a sidewall rubber containing de-dust carbon black and a preparation method of sidewall rubber containing dust carbon soot. According to the technical scheme of the invention, the sidewall rubber containing dust carbon soot is characterized by comprising the following components in parts by weight: 40-50 parts of natural rubber SMR20, 50-60 parts of 3-polybutadiene rubber, 40-47 parts of N375 carbon black, 1-9 parts of de-dust carbon black 2-5 parts of zinc oxide, 1-3 parts of stearic acid, 1-6 parts of 204 resin, 0.5-2 parts of antioxidant RD, 1-4 parts of antioxidant 4020, 0.5-2 parts of antioxidant 3100, 0.5-3 parts of microcrystal wax, 5-8 parts of aromatic oil, 1.2-1.7 parts of sulfur, 0.5-1 part of accelerant NS and 0.1-0.3 part of antiscorching agent CTP. Themethod can change the waste de-dust carbon black into valuable things and reduce the environmental pollution and the manufacture cost.

Description

technical field [0001] The invention discloses a sidewall rubber containing dust-absorbing carbon black, and also discloses a preparation method of the sidewall rubber containing dust-absorbing carbon black. Background technique [0002] At present, the mixture extracted from the dust extraction system in various tire enterprises is referred to as dust extraction carbon black for short. Based on the output of 2300 pieces / day, about 100kg of dust extraction carbon black can be discharged every day. The current treatment method is to add 1kg per vehicle in the production stage of the masterbatch of various rubber materials. There are many problems in this method. , easy to make mistakes; the third is that the environmental pollution is also more serious when cooperating. Contents of the invention [0003] One of the objectives of the present invention is to overcome the deficiencies in the prior art and provide a sidewall rubber containing dust-absorbing carbon black.
