Problems solved by technology

[0004] The tread rubber of traditional tires uses natural rubber as the base material, and through the combination of plasticizers, anti-aging agents, vulcanizing agents and other additives, the tire tread can have good wear resistance, tear resistance, and puncture resistance. However, the price of natural rubber is more expensive, which leads to higher production costs of tires. Therefore, many manufacturers will choose to add a small amount of reclaimed rubber to the rubber formula to save the amount of raw rubber and reduce production costs.
Reclaimed rubber is a process in which waste rubber is used to break part of the sub-

preparation example 1

[0037]Preparation example 1 of modified pottery clay: 1. add 10% of its weight to the potter's clay with a 5wt% hydrochloric acid solution to obtain acidified potter's clay;

[0038] ②The acidified pottery clay was roasted at 600°C for 2 hours, crushed and sieved to obtain roasted pottery clay;

[0039] ③ Take 30kg of water, 10kg of polyvinylpyrrolidone, 4kg of microcrystalline cellulose, 3kg of sodium lauryl sulfate, 0.3kg of N-(β-aminoethyl)-γ-aminopropylmethyldimethoxysilane, and mix Uniform, get the modifier;

[0040] ④Add 10% modifier by weight to the calcined pottery clay, stir at 1000r / min for 20min, dry at 120°C for 6h, and then pulverize through a 100-mesh sieve to obtain modified pottery clay.

Abstract

The invention discloses tread rubber for the tire of a dune buggy. The rubber comprises the following components in parts by weight: 10-15 parts of natural rubber, 8-12 parts of synthetic rubber, 35-45 parts of reclaimed rubber, 0.6-1 parts of sulfur, 0.6-1 parts of zinc oxide, 0.2-0.4 parts of stearic acid, 0.4-0.6 parts of an accelerant, 2-3 parts of carbon black, 2-3 parts of a reinforcing agent and 1.5-2 parts of an anti-aging agent. The reclaimed rubber is prepared by the following method: a, crushing waste tires to obtain waste rubber powder; b, adding a softener and a regenerant into the waste rubber powder, and performing banburying for 10-15 min at the temperature of 110-130 DEG C; and adding the reinforcing agent and the plasticizer to mix for 10-15 minutes at the temperature of50-60 DEG C, and performing cooling to obtain the reclaimed rubber. The tread rubber provided by the invention has the advantages of low cost, good wear resistance and good tear resistance.

Description

technical field [0001] The invention relates to the technical field of rubber materials, more specifically, it relates to a tread rubber for beach car tires. Background technique [0002] The English name of the ATV is All Terrain Vehicle (suitable for all terrain vehicles), and the English abbreviation is ATV, which refers to a vehicle that can drive on any terrain, also known as an all-terrain vehicle. It is used for driving on sandy ground, so it is commonly called ATV; ATVs are mostly used on relatively soft sandy soil, so ATV tires are required to have a larger ground contact area and a smaller tire than ordinary car tires. ground pressure. The tire is usually composed of three parts: the outer tire, the inner tube and the cushion belt. The outer tire is composed of the carcass, the buffer layer (or belt layer), the tread, the sidewall and the bead, and the tread rubber is used as the outermost part in contact with the road. The rubber layer is mainly used to prevent ...
