Anti-static rubber

Abstract

The invention relates to the field of chemical engineering material and safety protection, in particular to an anti-static rubber. The anti-static rubber is prepared form 24%-40% of nitrile rubber, 10%-16% of natural rubber, 15%-18% chlorinated polyethylene, 15%-30% of carbon black, 5%-6% of an anti-static agent, 1.8%-2.5% of an accelerant, 3%-4% of dibutyl ester and 10%-15% of titanium dioxide. According to the anti-static rubber, by adopting titanium dioxide to replace calcium carbonate as a padding due to the reinforcing, anti-aging and replenishing effects of titanium dioxide when adding titanium dioxide into rubber, from the perspective of physical performance, adding titanium dioxide instead of calcium carbonate makes rubber more aging resistant, insolation resistant, not prone to cracking, stable in color, large in stretch rate and strong in acid-base resistance property, besides improves ozone and ultraviolet resistant capability, and accordingly improves the performance of rubber pad when in use outside; the thermostability of titanium dioxide is high, and the heat resistance of the anti-static rubber pad is improved; besides titanium dioxide has semi-conductive property, is good in conductivity, improves the stability of resistance of the surface of the anti-static rubber pad, and accordingly the releasing ability to static of the anti-static rubber is improved.

Description

technical field [0001] The invention relates to the fields of chemical materials and safety protection, in particular to a formula of antistatic rubber. Background technique [0002] In daily life and work places, if there is a large amount of static electricity, it will bring harm to life and work. In some places where high-end precision instruments are used, static electricity will affect the sensitivity of the instrument, resulting in errors in test results; in addition, the existence of static electricity in the workshop will cause a large number of dust particles in the air to be adsorbed to the surface of objects, thus affecting the quality of products . The electric shock caused by static electricity not only brings discomfort, but also may cause more serious accidents due to people's evasive reaction after suffering the electric shock. When the operation is carried out in an environment of flammable and explosive dangerous goods, a certain amount of static electric...

[0003] At present, the antistatic rubber sold on the market is generally doped with 5%-7% calcium carbonate, but after using the antistatic rubber with the above ratio for a long time, we found that the 5%-7% calcium carbonate is due to the The proportion is too high, which in turn brings the following disadvantages: 1. The tensile strength is poor. Calcium carbonate will have a great impact on the tensile strength of natural rubber. Adding calcium carbonate to rubber can play the role of skeleton, that is, calcium carbonate The greater the content, the sharper the tensile strength of the rubber will drop; 2. The aging resistance is poor. After a period of use, the rubber is prone to aging reaction, th
