Abstract

The invention relates to a rubber additive. A chemical structural formula of the rubber additive is as shown in the description, wherein M is metal of which the oxidation state is positive 3 or positive 4 valence, R1 is an aliphatic chain which contains 5 to 50 carbon atoms, R2 and R3 are aliphatic chains which contain 0 to 50 carbon atoms, R4 is an aromatic nucleus compound, and n is a positive integer which is larger than or equal to 1. Metallic soap is made through the following ways of respectively putting aromatic carboxylic acid with aromatic amine and alkali as well as fatty acid and the alkali in polar solvents, carrying out heating reactions, mixing products of the aromatic carboxylic acid and the fatty acid, adding a metallic M salt solution in the products, obtaining a white solid product through a reaction, and obtaining a target product after washing and drying, wherein the metallic soap is mainly used as the additive for preparing rubber. Compared with the prior art, the rubber additive disclosed by the invention has the advantages that the preparation of the metallic soap is simple, the raw materials are easily obtained, and the tensile strength, the tear strength and the wet / slip resistance can be obviously increased when the metallic soap is added in the rubber.

Description

technical field [0001] The invention relates to the field of rubber additives, in particular to a rubber additive and its preparation and application. Background technique [0002] Vehicle fuel economy requires tires to provide the lowest possible rolling resistance, while vehicle safety considerations require tire treads to provide the highest possible traction, agile handling and driving stability. These properties of tire rubber are largely competing and contradictory based on various factors. Therefore, how to obtain a tire with low rolling resistance while having excellent anti-skid performance and a tread with stable driving remains a great challenge. Rolling resistance is the drag created by the tire in contact with the road as it rolls on the road, which causes the tire to dissipate energy as it rolls. The nature of this phenomenon is quite complex and can directly affect a vehicle's fuel consumption in almost all driving conditions. [0003] The rolling resistanc...
