High-performance rubber guide wheel for centerless grinding machine

Abstract

The invention discloses a high-performance rubber guide wheel for a centerless grinding machine. The high-performance rubber guide wheel for the centerless grinding machine is prepared from, by weight, 56-70 parts of natural rubber, 20-45 parts of ethylene propylene diene monomer, 16-20 parts of styrene-butadiene rubber, 1.2-1.8 parts of zinc oxide, 0.7-1.5 parts of sulfur, 1-2 parts of dicumyl peroxide, 0.2-0.8 part of accelerant CBS, 0.8-1.5 parts of accelerant NOBS, 1-1.8 parts of accelerant PZ, 20-35 parts of modified epoxy resin, 15-35 parts of modified ferroferric oxide, 50-60 parts of white carbon black, 5-15 parts of nanometer glass beads, 0.5-2.5 parts of phenyltriethoxysilane, 0.8-1.6 parts of isopropyl dioleic(dioctylphosphate) titanate, 2-6 parts of caprolactam, 10-20 parts of nano ceramic microspheres, 4-10 parts of graphene, 5-15 parts of kaolin, 0.5-1.5 parts of stearic acid, 1-2 parts of pine tar, 1-2 parts of castor oil, 1-2 parts of coumarone and the like.

Description

technical field [0001] The invention relates to the technical field of rubber, in particular to a high-performance rubber guide wheel for a centerless grinder. Background technique [0002] Centerless grinding machine is also called centerless cylindrical grinding machine. The workpiece is supported between the rubber guide wheel and the carriage, and the rubber guide wheel drives the workpiece to rotate. With the rapid development of modern science and technology, the machining accuracy and production efficiency have been greatly improved. The traditional The rubber guide wheel is far from meeting the high-quality requirements of the modern mechanical grinding industry. The hardness of the rubber guide wheel currently on the market is in the medium-hard range, which is not suitable for the grinding of cemented carbide. In addition, when high-hardness workpieces pass under high temperature conditions , will leave scratches on the rubber guide wheel, costing money and effort....
