Abstract

The invention relates to tread rubber filled with environment-friendly white carbon black and butadiene styrene rubber and a preparation method of the tread rubber. The tread rubber comprises the following components in parts by weight: 25-40 parts of natural rubber, 60-75 parts of butadiene styrene rubber, 25-45 parts of carbon black, 15-35 parts of white carbon black, 2-4 parts of aromatic oil,1.5-2.5 parts of stearic acid, 3-4 parts of zinc oxide, 1-2 parts of tackifying resin, 1.5-2 parts of anti-cracking resin, 1.5-2.5 parts of an anti-ager 4010NA, 1.5-2 parts of microcrystalline wax, 1.2-1.5 parts of an accelerator NOBS, 0.3-0.5 part of an accelerator TMTD, 1.5-2 parts of sulfur and 0.1-0.3 part of a scorch retarder. The components are subjected to primary mixing, secondary mixing and final mixing to obtain the tread rubber. The preparation method is simple and easy to operate in step; owing to modified rice-husk-source white carbon black, clustering in basic rubber can be reduced; the machinability and the wear resistance of the tread rubber are improved; rolling resistance of a tire can be effectively reduced; and the wet-skid resistance is improved.

Description

technical field

[0001] The invention relates to an environment-friendly filling white carbon black styrene-butadiene rubber tread rubber and a preparation method thereof, belonging to the technical field of tread rubber preparation. Background technique

[0002] SBR is a high polymer elastomer obtained by catalytic copolymerization of butadiene and styrene in emulsion or solution, and is an unsaturated hydrocarbon high polymer. The processing performance of styrene-butadiene rubber is slightly lower than that of natural rubber, and its physical and mechanical properties and product performance are close to those of natural rubber. The most important thing is that styrene-butadiene rubber has better wear resistance, wet skid resistance and rolling resistance than natural rubber. , To meet the concept of "green tires", the raw rubber in the tread rubber formula here is a compound system of styrene-butadiene rubber and natural rubber.

[0003] In recent years, silica has becom...
