High-strength automobile tire and its preparation method

Abstract

The invention discloses a high strength automobile tire and a preparation method thereof. The preparation method comprises the following steps: 1) peeling and crushing green bamboo and calcining the green bamboo in protective gas to obtain bamboo charcoal, 2) roasting titanium dioxide, barium carbonate, lithium carbonate and the bamboo charcoal in protective gas to obtain modified barium metatitanate, 3) carrying out gelatinization on tetraethylthiuram disulfide, starch, caryophyllene, methylcellulose and water to obtain a modified vulcanizing agent, and 4) carrying out primary mixing on butadiene rubber, an ethylene-propylene copolymer, poly(ethylene glycol methyl ether), pentaerythritol triacrylate, glycerol, nanometer calcium carbonate, dimethyldiethoxysilane, zinc sulfide, dicumyl peroxide and sulfur, then adding the modified barium metatitanate and the modified vulcanizing agent into the mixture, carrying out secondary mixing and carrying out molding and cooling to obtain the high strength automobile tire. The high strength automobile tire has excellent high temperature resistance, aging resistance and mechanical properties.

Description

technical field

[0001] The invention relates to an automobile tire, in particular to a high-strength automobile tire and a preparation method thereof. Background technique

[0002] Automobile tires are one of the important parts of automobiles. Their main functions are: to ease the impact of the car while driving together with the car suspension, to ensure that the car has good seating comfort and smooth driving; to ensure that the wheels and the road surface have Good adhesion, improve the traction, braking and passability of the car; bear the weight of the car. As a result, the important role played by tires on automobiles has been paid more and more attention by people.

[0003] The advent of rubber tires was a prerequisite for the further development of automobiles. When it comes to rubber, people naturally think of Charles Goodyear, the father of rubber. In 1834, inspired by coke steelmaking, he began experimenting with the hardening of soft rubber. After countless ...
