Abstract
The invention discloses a polyurethane elastomer rubber roller with long service life. The elastomer rubber roller comprises a roller body that comprises an inner layer, protruding blocks and an outerlayer; the outer layer is located on the surface of the inner layer, a plurality of protruding blocks are arranged on the surface of the inner layer, the inner layer comprises a bonding layer, a strength layer, a main body layer and an antirust layer, wherein the bonding layer is located on the outer surface of the strength layer, and the strength layer is located on the outer surface of the mainbody layer. According to the invention, the inner layer and the outer layer can be bonded through the bonding layer, wherein the convex blocks can limit the outer layer, thereby avoiding sliding andoblique of an outer layer; a tear-resistant layer increases the strength of the outer layer, so that the outer layer is prevented from being torn and damaged, the strength layer increases the strengthof the roller body, the chemical property is stable, the high-temperature resistance is high, deformation and damage of the roller body are avoided, the main body layer guarantees the strength and hardness of the roller body, the rust-proof layer prevents the main body layer from being rusted, and thereby the problems that an existing polyurethane elastomer rubber roller is short in service life,not high in strength and prone to being torn are solved.
Description
technical field [0001] The invention relates to the technical field of rubber rollers, in particular to a polyurethane elastomer rubber roller with long service life. Background technique [0002] The rubber roller is a roller-shaped product made of metal or other materials as the core and covered with rubber by vulcanization. It can be divided into papermaking rubber rollers, printing and dyeing rubber rollers, printing rubber rollers, hulling rubber rollers, and metallurgical rubber rollers. And oil printing rubber rollers, etc., the colloid for polyurethane rubber rollers has sufficient surface viscosity, which can ensure that the rubber rollers have good ink transfer and ink holding performance during the printing process, and its good ink affinity can ensure high-quality printing, but the existing High-quality polyurethane elastomer rubber rollers have short service life, low strength, and are easy to be torn. Therefore, we propose a polyurethane elastomer rubber roller...
