[0014] The invention provides a method for preparing a high-temperature-resistant automobile tire, comprising:

[0015] 1) Peel green bamboo, crush it, and then calcinate it in the presence of protective gas to make bamboo charcoal;

[0016] 2) Roasting titanium dioxide, barium carbonate, lithium carbonate and bamboo charcoal in the presence of protective gas to prepare modified barium metatitanate;

[0017] 3) Gelatinizing tetraethylthiuram disulfide, starch, caryophyllene, methylcellulose and water to prepare a modified vulcanizing agent;

[0018] 4) Butadiene rubber, methacrylic acid-butadiene-styrene copolymer, polyethylene oxide, pentaerythritol triacrylate, glycerin, nano-calcium carbonate, dimethyldiethoxysilane, zinc sulfide, over Benzoyl oxide and sulfur are mixed for the first time, then modified barium metatitanate and modified vulcanizing agent are added for second mixing, and finally molded and cooled to obtain high-temperature resistant automobile tires.

Abstract

The invention discloses a high-temperature-resistant automobile tire and a preparation method thereof. The preparation method comprises the steps that 1, green bamboos are peeled and smashed and then are calcined in the presence of shielding gas to obtain bamboo charcoal; 2, nano titanium dioxide, barium carbonate, lithium carbonate and the bamboo charcoal are calcined in the presence of shielding gas to obtain modified barium metatitanate; 3, tetraethylthiuram disulfide, starch, caryophyllene, methylcellulose and water are subjected to gelatinization processing to obtain a modified vulcanizing agent; 4, butadiene rubber, a methyl acrylic acid-butadiene-styrene copolymer, polyethylene oxide, pentaerythritol triacrylate, glycerol, nano calcium carbonate, dimethyldiethoxylsilane, zinc sulfide, benzoyl peroxide and sulfur are mixed primarily, then the modified barium metatitanate and the modified vulcanizing agent are added for secondary mixing, and finally forming and cooling are performed to obtain the high-temperature-resistant automobile tire. The automobile tire prepared by adopting the method has excellent high-temperature-resistant, aging-resistant and mechanical properties.

Description

technical field [0001] The invention relates to automobile tires, in particular to a high-temperature-resistant 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. Aft...
