The invention discloses a novel rubber activator and a preparation method thereof. The rubber activator particularly comprises 20 to 80 percent of aromatic group-containing formic acid type metal salt and 20 to 80 percent of zinc oxide, wherein the aromatic group-containing formic acid type metal salt is mixed with the zinc oxide at normal temperature and the two are stirred for 5 to 15 minutes at the rotation speed of between 2,000 and 3,500rpm. Compared with the prior art, the problems of high zinc content and high heavy metal element content in the zinc oxide can be effectively solved, density is reduced, dispersibility is improved, and the novel rubber activator improves rubber tensile property, broken chain elongation rate and rubber cross-linking effect.
Description
technical field [0001] The invention relates to an activator for rubber. Background technique [0002] Rubber activators are used in the rubber vulcanization process to speed up the vulcanization rate and increase the degree of vulcanization, and are essential rubber additives. Since the 1920s and 1930s, zinc oxide has been used as an activator in rubber until now, and it is the rubber activator with the largest amount and the largest market capacity. However, zinc oxide has inherent defects such as high zinc content, high content of heavy metal elements such as lead, manganese, and copper, high density, and poor dispersion performance. The extensive use of zinc oxide poses a huge environmental threat. Therefore, actively looking for and developing zinc oxide substitutes or upgraded products has become a topic of great concern to the rubber industry, and low zinc content or zinc-free activators will become the general trend. After years of scientific and technological inno...
