Problems solved by technology

Therefore, various compounds have been proposed as additives for rubber at present. For example, in Japanese Patent Application Laid-Open No. 2003-138077, it is proposed to add a specific carboxylate amine salt with vulcanization acceleration to halogen-based saturated rubber. It has a certain effect, but still needs to further improve the vulcanization characteristics and viscoelastic properties

Abstract

Disclosed is a hydroxy acid amine salt represented by the general formula (I) below. Also disclosed are a method for producing such a hydroxy acid amine salt, and a rubber composition containing such a hydroxy acid amine salt. (In the formula, R1, R2, R3, R4, k, l, m and n are as defined in the description).

Description

technical field [0001] The present invention relates to a novel hydroxyacid amine salt, its preparation method and rubber composition containing the hydroxyacid amine salt. Specifically, the present invention relates to a hydroxyacid amine salt capable of improving the vulcanization properties and viscoelastic properties of silicone rubber, its production method, and a rubber composition containing the hydroxyacid amine salt. Background technique [0002] When various additives such as reinforcing fillers are added to the rubber component and rubber compositions are manufactured, it is required not only to have good viscoelastic properties after vulcanization, but also to ensure that the rubber composition has good vulcanization properties to improve productivity. Therefore, various compounds have been proposed as additives for rubber at present. For example, in Japanese Patent Laid-Open No. 2003-138077, it is proposed to add a specific carboxylate amine salt with vulcanizat...
