Problems solved by technology

However, in the rubber compound formulation, in addition to the raw rubber system, the selection and proportioning of various additives have a great influence on the properties of the rubber compound, and the application does not disclose that the nylon short fibers in the formula are particularly adhesive Substances, semi-effective vulcanization system component substances and anti-aging substances are the specific choices, and the selection of these additives not only affects the performance of the rubber compound, but also affects whether the product is environmentally friendly, and then affects whether the product can enter the corresponding country or area

Abstract

The invention discloses environmentally-friendly cutting-resistant off-the-road tyre tread rubber. The environmentally-friendly cutting-resistant off-the-road tyre tread rubber comprises, by weight, 100 parts of natural rubber, 45-65 parts of N115 carbon black, 1-3 parts of aramid short fibers, 0.5-3.5 parts of environmentally-friendly aromatic oil, 3-7 parts of zinc oxide, 0.5-2.5 parts of stearic acid, 0.5-2.5 parts of N-isopropyl-N-phenyl-para-phenylene diamine, 0.5-2.5 parts of 2,2,4-trimethyl-1,2-dihydroquinoline polymer, 0.5-2.5 parts of protection wax, 0.8-1.2 parts of sulphur, 0.5-1.7 parts of N-cyclohexyl-2-benzothiazolylsulfenamide and 0.1-0.5 parts of an anti-scorching agent CTP. The environmentally-friendly cutting-resistant off-the-road tyre tread rubber satisfies REACH regulations, has the characteristics of excellent cutting resistance, wear resistance and collapse resistance and realizes good balance between toughness, a thermogenesis value, heat aging resistance and wear resistance.

Description

technical field [0001] The invention relates to tires, in particular to an environment-friendly and cut-resistant engineering machinery tire tread rubber. Background technique [0002] Construction machinery tires have low speed, heavy load, short haul distance, and frequent turns. The tread rubber generally requires cutting resistance, needle stick resistance, chipping resistance, small deformation, and low heat generation. The existing tire tread materials for construction machinery are mainly composed of raw rubber system, reinforcement system and vulcanization system. Comprehensive balance of heat generation performance; the reinforcement system mainly adopts fine particle carbon black of N220 or N110 system and its derivatives for reinforcement filling, and the vulcanization system generally adopts ordinary vulcanization system. [0003] The use of styrene-butadiene rubber can increase the cutting resistance and wear resistance of the rubber to a certain extent, but it...
