Problems solved by technology

[0004] However, in the existing process of preparing cobalt boroacylate, the methods of neutralization, boroacylation, and additive addition are generally adopted. Because in this method, acid-base neutralization is not very strong, the short-chain acid used is other lower fatty acids. , the neutralization effect is unstable, and the shortening of the production time cannot be realized, and the stability of the fina

Abstract

The invention provides a preparation method of cobalt boracylate, belonging to the field of the preparation of composite material accelerating agent. The preparation method comprises the following steps: mixing neodecanoic acid, isooctyl acid, glacial acetic acid, dimethylbenzene and cobalt hydroxide, carrying out acid-base neutralization reaction, and obtaining an intermediate product after the neutralization reaction is finished; adding tributyl borate into the obtained intermediate product and carrying out boracylate reaction, adding calcium borate as additive simultaneously, and obtaininga reaction product, namely, cobalt boracylate after the boracylate reaction is finished. In the preparation method, the neodecanoic acid, the isooctyl acid, the lower fatty acid glacial acetic acid and the dimethylbenzene are matched and carry out the acid-base neutralization reaction together with the cobalt hydroxide to generate the intermediate product; the reaction velocity can be improved andthe forming of the intermediate product is accelerated due to the effects of the glacial acetic acid and the dimethylbenzene; in addition, in the final boracylate reaction, as the calcium borate as the additive is added together with the tributyl borate, the reaction time is effectively shortened, and the insoluble substance performance and the anti-static property of the cobalt boracylate whichis prepared finally are improved.

Description

technical field [0001] The invention relates to the field of preparation of adhesion promoters, in particular to a preparation method of cobalt boroacylate which can be used as a rubber adhesion promoter. Background technique [0002] From the point of view of the adhesion mechanism between metal and rubber, as long as it is a salt containing cobalt, it can improve the adhesion between metal and rubber to varying degrees. The earliest cobalt salts used by people were water-soluble inorganic cobalt salts, such as cobalt chloride and cobalt sulfate. Mixing these cobalt salts in rubber or coating them on the metal surface can improve the adhesion between metal and rubber to a certain extent. But at the same time found. When heat-aged, its adhesion drops sharply. Subsequently, people switched to cobalt salts as rubber adhesion promoters. After research, it was found that cobalt salts adhesion promoters can greatly improve the adhesion between metal and rubber compared with the...
