Abstract

The invention discloses a polyurethane rubber roller. The polyurethane rubber roller is prepared from the following materials in parts by weight: 50 parts of polytrimethylene glycol, 20-30 parts of toluene diisocynate, 20-30 parts of methanol, 30-40 parts of diethanol amine, 5-10 parts of glycerol, 15-25 parts of 3,3-dichloro-4,4-diaminodiphenyl-methane, 0.5-1.0 part of titanium dioxide and 10-15 parts of spindle oil. The rubber roller is excellent in wear resistance, high temperature resistance, corrosion resistance and antiaging performance, and can be continuously used for 3-4 months under a high-rotation-speed work environment without any change.

Description

technical field [0001] The invention relates to a rubber, in particular to a polyurethane rubber roller. Background technique [0002] The colloid for polyurethane rubber rollers has sufficient surface viscosity, which can ensure good ink transfer and ink holding performance of the rubber roller during the printing process, and its good ink affinity can ensure high-quality printing; the appearance is bright, the surface of the colloid is fine and smooth, The colloidal material and the mandrel are firmly bonded. The size of the rubber roller is strictly controlled, and the size will not change greatly under different temperature and humidity conditions. It can adapt to the high-temperature and high-humidity environment of the printing workshop in the south and the severe cold and dry climate in the north; the polyurethane rubber roller has good chemical properties and is suitable for various types of inks and printing methods. It has special resistance to solvent components...
