Formula of cobalt salt adhesion promoter

Abstract

The invention relates to a formula of a cobalt salt adhesion promoter. An interpenetrating network shape is formed by a molecular structure of a cobalt salt product, so that the crosslinking promotingaction of the product in a rubber product is improved and the adhesive force of a steel wire in the rubber product is improved. The formula of the cobalt salt adhesion promoter is prepared from the following substances in parts by weight: 30-50 parts of a secondary octanol solvent, 31.54-33.2 parts of Co(OH)2, 56-65 parts of capric acid, 10-15 parts of mixed valeric acid, 5-8 parts of mixed acetic acid and propionic acid, 2-4 parts of a cosolvent and 6-10 parts of butyl stearate.

Description

technical field [0001] The invention belongs to chemical production raw materials, in particular to a formula of cobalt salt adhesion promoter, a processing aid used in the production of rubber products. Background technique [0002] At present, the import of cobalt salt adhesion promoters used in the domestic tire rubber processing industry is increasing continuously. Although a few domestic chemical companies also produce such products, due to technical difficulties, unreasonable composition and backward technology, the products produced The quality of the products is not stable and is rarely recognized by users. The cobalt salts produced by some domestic enterprises are generally based on two-acid or three-acid cobalt salts. The two-acid cobalt salts are made of capric acid and propionic acid, and the tri-acid cobalt acid and acetic acid as raw materials, the cobalt salt products produced by the two-acid method have a high softening point, generally above 110°C, and even...
