Abstract

The invention discloses an off-the-road tire abrasion-resistant formula. The off-the-road tire abrasion-resistant formula is characterized by comprising, by weight, 80-100 parts of butadiene-styrene rubber, 0-20 parts of modified butadiene-styrene rubber, 40-70 parts of carbon black, 0-15 parts of white carbon black, 4.5-9.5 parts of anti-aging agent, 4-9 parts of active agent, 4-10 parts of tackifier, 2.7-5.5 parts of vulcanization accelerator, 0.15-0.5 part of scorch retarder, 6-12 parts of softener and 1.5-3 parts of processing agent. The preparation method includes the steps that the butadiene-styrene rubber, the modified butadiene-styrene rubber, the anti-aging agent, the active agent, the tackifier and the processing agent are thrown into an internal mixer to be mixed first; the 2/3 weight part of carbon black and the white carbon black are thrown to be mixed; then the other 1/3 weight part of carbon black is thrown to be mixed; at last, the softener is thrown to be mixed, and sheet discharging and cooling are carried out. The weather resistance, heat resistance, cut growth resistance and abrasive resistance of a tire are improved, and the formula is particularly suitable for off-the-road tires; when the formula is used in a tread, the service life of the tire can be greatly prolonged, and the chunking and chipping resistance of the tire can be greatly improved.

Description

Technical field: [0001] The invention relates to the technical field of engineering machinery tires, in particular to a wear-resistant formula for engineering machinery tires and a preparation method thereof. Background technique: [0002] OTR tires are mainly used in harsh road conditions such as underground mines and mines. Due to the harsh road conditions, the tire tread is prone to chipping and chipping, which affects its service life. Therefore, the wear resistance and chipping resistance of the tread are improved. Block performance is of great significance to prolong the service life of tires. Invention content: [0003] The purpose of the present invention is to overcome the shortcomings of the above-mentioned prior art, and provide a kind of engineering machinery tire formula. [0004] Another object of the present invention is to provide a method for preparing an engineering machinery tire formula. [0005] The invention mainly solves the problem that the tread ...
