Abstract

The invention relates to the technical field of organic silicon, and specifically discloses a modified white carbon black. The modified white carbon black comprises 10-16 parts of fly ash; 28-45 parts of sodium carbonate; and 31- parts of p-toluenesulfonic acid 48 parts; 1.3 parts-2.4 parts of dimethyldimethoxysilane; 52 parts-81 parts of n-octanol; 24 parts-36 parts of ethanol; 58 parts-74 parts of water; Sodium carbonate reaction, followed by acid leaching with p-toluenesulfonic acid; modified by adding dimethyldimethoxysilane and n-octanol to obtain modified white carbon black. Also disclosed is a silicone rubber for rubber rollers containing modified white carbon black, comprising 100 parts of methyl vinyl silicone rubber; 10 to 90 parts of modified white carbon black; the preparation method is: The rubber and modified silica are added to the kneader and mixed into a mass. The silicone rubber produced by the invention does not add a structure control agent, and can significantly improve the resilience and processing performance.

Description

technical field [0001] The invention relates to the technical field of organosilicon, more specifically, it relates to a silicone rubber for rubber rollers containing modified white carbon black and a preparation method thereof. Background technique [0002] Silicone rubber is widely used in the rubber roller industry. The structural control agent is mainly silicone oil or diphenylsilanediol containing hydroxyl, methoxyl, and ethoxyl groups. Its function is to shorten the kneading molding time and treat fillers The hydroxyl group in silica can prolong the storage time of silicone rubber, improve the processability of silicone rubber, and avoid the structure of the rubber compound. It is an essential ingredient in the silicone rubber formula. [0003] Related technologies, such as Chinese Invention Patent Application Publication No. CN102070905B disclose a composite silicone rubber and its preparation method, wherein the composite silicone rubber is composed of the following ...
