Problems solved by technology

However, because AT has a large specific surface area and a large amount of silanol on the surface, it has high surface activity and is easy to aggregate; when it is used as a reinforcing agent for rubber materials, it is difficult to exist in the rubber matrix in the form of nano single crystals

Abstract

The invention provides a colored hand cart tire rubber material filled with semi-wet modified attapulgite. The colored hand cart tire rubber material comprises the following components in parts by mass: 70 parts of natural rubber, 30 parts of butadiene styrene rubber, 20-60 parts of semi-wet modified attapulgite, 0-25 parts of precipitated silica, 1.4-1.6 parts of a vulcanizing agent, 1.4-1.9 parts of an accelerant system, 5-8 parts of zinc oxide, 2-4 parts of stearic acid, 0-0.75 part of a white carbon black modifier, 3.5 parts of an anti-aging agent system, 4-6 parts of solid coumarone and 0.4-0.6 part of a colorant. The traditional rubber processing material and process are adopted, and the industrial-grade semi-wet modified attapulgite is applied to a colored hand cart tire, which is a development of a novel application field of attapulgite and is beneficial to the popularization and application of the semi-wet modified attapulgite to hand cart tire enterprises.

Description

Technical field [0001] The present invention is a rubber product technology field, which involves color force car tires and preparation methods that fill the semi -wet -wetting method. Background technique [0002] my country has more than 300 companies and more than 100,000 employees. With the continuous improvement of its technology, production equipment and product quality, it not only plays an important position in my country's rubber industry, but also ranks among the top in the world.The tires mainly include the internal and external tires of motorcycles, internal and external tires of bicycles, internal and external tires, and multi -purpose tires.According to statistics from the Chinese rubber industry's economic operation in 2014, the annual output of motorcycle tires in my country in 2014 was 170 million, the annual output of bicycle tires was 350 million, and the annual output of electric bicycle tires was 245 million. The amount continues to grow.It can be seen that t...
