Problems solved by technology

Due to cost reasons, the softener oil in the formula is still commonly used ordinary aromatic oil. The finished tire made of this formula has high rolling resistance and poor wet skid resistance, and does not meet the requirements of the EU REACH regulation or the classification stipulated in the EU tire labeling law non-competitive class status in the standard

Abstract

The invention discloses a tyre crown rubber material. The tyre crown rubber material comprises the following raw materials in parts by weight: 60-80 of natural rubber, 20-40 of butadiene rubber BR9000, 0-0.4 of peptizer, 10-30 of intermediate super abrasion furnace black, 25-45 of white carbon black, 3-7 of silane coupling agent, 3-5 of zinc oxide, 1-4 of stearic acid, 1-3 of antiager 6PPD, 0-2 of antiager RD, 1-3 of microcrystalline paraffin, 1-3 of sulfur, 1.5-2.5 of accelerator, 4-6 of fatty acid salt processing agent, 0-1 of anti-reversion agent, 2-5 of environment-friendly arene oil TDAE (Treated Distillate Aromatic Extract), 1-3 of octyl phenolic aldehyde tackifying resin and 0-0.3 of scorch retarder. When mixing is carried out in three sections, partial formula raw materials are subjected to rubber material mixing, and then other formula materials are added for rubber material mixing. The tyre crown rubber material produced by using the tyre crown rubber material formula is good in comprehensive processing property, has the characteristics of low thermogenesis, ageing resistance and tearing resistance and is environment-friendly and can be used for producing green full-steel radial tyre crown.

Description

technical field [0001] The invention relates to the rubber field, in particular to a tire crown rubber material and a mixing method thereof. technical background [0002] As the number of cars continues to increase, the negative impact it brings is also increasing. According to some data, more than 200 million tons of carbon monoxide are emitted into the atmosphere by automobiles every year, accounting for more than 1 / 3 of the total amount of poisonous gas, making it the largest amount of poisonous gas in the urban atmosphere. On the other hand, the contradiction between huge energy consumption and dwindling oil resources is becoming increasingly prominent. At the same time, consumers' requirements for low fuel consumption and high environmental protection are also increasing day by day. [0003] As one of the key load-bearing components of a car, tires have an important impact on the fuel economy, safety and handling of the car. The rolling resistance of tires accounts f...
