Origin Of SUNNYJOINT Rubber Additives

- Oct 10, 2018-

Shenyang SUNNYJOINT as a supplier of Rubber Additives has vulcanization from natural rubber. After more than 80 years of research, until the 1920s and 1930s, with the basic varieties of vulcanization accelerators 2-mercaptobenzothiazole and its sulfenamide derivatives and industrialization of p-phenylenediamine antioxidants, rubber additives Only form a system. At present, rubber auxiliaries are in a stable period, and the production of two main types of organic auxiliaries, vulcanization accelerators and anti-aging agents, is about 4% of the raw rubber consumption. The production of foreign rubber auxiliaries is quite concentrated. Bayer AG of the Federal Republic of Germany and Monsanto of the United States are the main manufacturers. The production of Chinese rubber auxiliaries (referred to as organic auxiliaries) began in 1952.


In the process of processing tires, the rubber is subjected to rubber mixing, vulcanization and other processes, and under the action of high temperature and high pressure, some toxic and harmful gases are released. These gases hinder people's health. To improve the working environment of operators and reduce toxic and harmful gases, it is important to eliminate those toxic and harmful rubber auxiliaries and adopt environmentally friendly rubber auxiliaries.

During the use of the tire, the tire continues to be exposed to high temperature and high pressure, causing the tire to age and release some harmful gases. The United States has used this to set up barriers to the export of some tire companies in China. Japan Bridgestone Tire Co., Ltd. has developed a unique additive to inhibit the tire from being hardened during use due to the heat generation, so that the sulfur and rubber molecules continue to crosslink and harden the tire rubber, improving the braking and traction of the tire. Sex and tire noise.

The noise of the tire is also an environmental pollution. Thousands of cars on a road will continue to drive, which will resonate, which will affect people's rest and sleep. The establishment of noise isolation zones on both sides of urban elevated roads is a negative approach. Fundamentally, it is still necessary to improve the structure of the tire and the formulation of the rubber.


In recent years, China's rubber auxiliaries industry has also developed rapidly. Especially after some foreign-funded companies have entered this field, China's rubber auxiliaries have greatly improved in quantity, quality and technology, and can basically meet the rubber industry in China. Demand. However, some rubber auxiliaries suitable for high-performance radial tires with low dosage, good quality and high performance need to be imported. Therefore, China's rubber auxiliaries industry should increase investment in science and technology, strive to innovate, and actively develop new rubber auxiliaries suitable for the development of China's tire industry. Of course, to complete this task, the tire industry has an unshirkable responsibility. Therefore, it is hoped that tire companies, rubber auxiliaries and rubber research institutes will actively join hands to strengthen cooperation and take the path of joint development to shorten the gap between rubber auxiliaries and foreign rubber auxiliaries in China as soon as possible. In the rubber auxiliaries industry, nano zinc oxide, nano carbon black, nano calcium carbonate, etc. are also actively developed. These nano-scale rubber auxiliaries are very beneficial for improving the quality of rubber compounds and improving tire performance. In short, China's rubber additives must have high-tech content, in order to be invincible in the fierce market competition.
