Abstract

The invention discloses a preparation method of carboxylated acrylonitrile butadiene rubber latex with high solid content. The preparation method of the carboxylated acrylonitrile butadiene rubber latex with high solid content comprises that the carboxylated acrylonitrile butadiene rubber latex is prepared from the following raw materials: 20%-30% of carboxylated butadiene-acrylonitrile rubber, 15%-25% of phenolic rubber, 10%-20% of ethanedioic acid diethyl ester, 5%-15% of dimethyl sebacate, 5%-10% of an organosilicone waterproof agent, 15%-25% of modified starch and 5%-15% of deionized water. According to the preparation method of the carboxylated acrylonitrile butadiene rubber latex with high solid content, production and processing are carried out by adopting a reasonable material ratio; the technological process is simple and easy to control, and efficient production is facilitated; meanwhile, the solid content is improved by adding the modified starch, the quality and performanceof the latex are effectively improved, improvement of the alkali-resistant and antioxidant effects is facilitated, and application and popularization are facilitated.

Description

technical field [0001] The invention relates to the technical field of nitrile latex, in particular to a method for preparing carboxylated nitrile latex with high solid content. Background technique [0002] In the current industrial production, carboxylated nitrile latex is widely used, so large-scale and efficient production is required. [0003] However, the existing method of preparing carboxy-topped latex is relatively complicated, which is not conducive to stable and efficient production. In addition, the material configuration in the existing method is unreasonable, the solid content of the latex is low, and the use effect is not ideal, so it needs to be improved for production. Contents of the invention [0004] The objective of the invention is in order to solve the shortcoming that exists in the prior art, and the preparation method of a kind of high solid content carboxylated nitrile latex that proposes. [0005] In order to achieve the above object, the presen...
