Abstract

The invention discloses a rubber composition containing an organic acid zinc phenolic resin compound, a preparation method and an application thereof. The rubber composition comprises 100 parts of rubber, 1.0 to 30.0 parts of organic acid zinc phenolic resin compound, 40.0 to 120.0 parts of carbon black and 3.0 to 10.0 parts of sulfur, and may also contain process oil, vulcanization accelerator, methylene donor and other additives. Among them, the coordination cross-linking bond formed by the organic acid zinc phenolic resin compound can increase the strength and heat resistance of the phenolic resin, and the structure of the organic acid can also increase the compatibility between the phenolic resin and rubber, and the compound will improve the phenolic resin. The rubber composition has the characteristics of high modulus, low initial Mooney viscosity, improved fatigue life, and outstanding mechanical properties after high temperature aging.

Description

technical field [0001] The invention relates to the field of rubber materials, in particular to a rubber composition containing an organic acid zinc phenolic resin compound and a preparation method and application thereof. Background technique [0002] The apex is the main filler in the bead part and plays a role in supporting the sidewall. The bead of the tire is a rigid structure, which plays the role of bearing and fixing, and the sidewall is an elastic structure, which has the function of cushioning and vibration reduction. If the rigid structure is directly connected to the elastic structure, the joint is easily broken, so connecting the bead and the sidewall through the apex can play a role of slow transition. Therefore, the apex rubber is required to have high hardness, high rigidity but not brittleness, and certain flex resistance. Under the premise of ensuring the good processing performance, flex resistance, heat aging resistance and low heat generation of the ap...
