Problems solved by technology

[0006] Aiming at the problem that the existing high-temperature-resistant rubber rollers will cause rubber thermal-oxidative aging damage during use, the present invention provides a short-fiber reinforced high-temperature-resistant rubber roller, a rubber roller rubber material and a manufacturing method thereof. Distributed short fibers, when there are irregular cracks on the surface of rubber due to thermal oxygen aging, the short fibers can prevent the cracks from forming and gradually expanding, which enhances the high temperature resistance of the rubber material and greatly prolongs the service life of the rubber roller

Abstract

The invention discloses a short fiber-reinforced high temperature-resistant rubber roll, a rubber roll rubber material and preparation methods thereof, and belongs to the technical field of rubber rolls. The rubber roll rubber material comprises the following components in parts by weight: 100 parts of ethylene propylene rubber, 50-80 parts of rapidly-extruded carbon black, 10-20 parts of a plasticizer, 3-5 parts of nanometer active zinc oxide, 2-6 parts of an anti-aging agent, 6-10 parts of a crosslinking agent, 2-10 parts of an assistant crosslinking agent, 3-8 parts of tackifying resin, 2-5 parts of a dispersing flowable agent and 2-10 parts of short fiber. The preparation method of the rubber roll comprises the following steps: preparing the rubber material, wrapping with the rubber material, vulcanizing in a vulcanizing tank, and turning. The rubber material is high in strength, rebound resilience, and resistance to high temperature and low in permanent compression deformation; the rubber roll made of the rubber material is high in resistance to high temperature and acid and alkali corrosion; the rubber roll is highly consistent in inside and outside hardness and material distribution and high in roller surface machining precision; the service life of the rubber roll is twice of or longer than that of the conventional high temperature-resistant rubber roll, so that the service life of the rubber roll is greatly prolonged.

Description

technical field [0001] The invention belongs to the technical field of rubber rollers, and relates to a short-fiber-reinforced high-temperature-resistant rubber roller, a rubber roller rubber material and a manufacturing method thereof, and more specifically, relates to a rubber roller used in metallurgy, non-ferrous metal processing, chemical fiber printing and dyeing, and papermaking. High temperature resistant rubber rollers used in high temperature or high temperature and high corrosion environment. Background technique [0002] Rubber roller is a roller-shaped product made of metal or other materials as the core and covered with rubber by vulcanization. With the rapid development of metallurgy, non-ferrous metal processing, chemical fiber, papermaking and other industries, the speed of production lines and the temperature of high-temperature stations have increased, and high-temperature-resistant rubber rollers used in high-temperature, high-humidity and strong corrosiv...
