Embodiment 1

[0049] The invention relates to a sea-island structure rubber roller. The rubber layer of the sea-island structure rubber roller is prepared by kneading a matrix compound rubber and individual granule rubber. The master compound rubber and the individual granule rubber use nitrile rubber as the raw material, and the master compound rubber is obtained through mixing, and the individual granule rubber is obtained through mixing, vulcanization, crushing and sieving. Heat the matrix rubber mixture and cover the rolls; add the individual granules in batches, and wait until the individual granules are completely integrated into the matrix rubber to obtain the rubber layer of the sea-island structure rubber roller.

[0050] In the processing process of this embodiment, it is ensured that the elongation of the matrix compound is 220% higher than that of the individual granules, and the Shore A hardness of the matrix compound is 14 degrees lower than that of the individual granules. Th...

Abstract

The invention discloses a rubber covered roller of an island structure and a preparation method thereof, and belongs to the technical field of rubber covered rollers. According to the rubber covered roller of the land structure, a rubber layer is prepared by mixing a parent rubber compound and individual particle glue. The elongation of the parent rubber compound is 100-200% higher than that of the individual particle glue, the strength of the parent rubber compound is 4-8MPa higher than that of the individual particle glue, and the Shore A hardness of the parent rubber compound is 8-14 degrees lower than that of the individual particle glue. The preparation method of the rubber covered roller of the island structure comprises the steps of mixing, vulcanizing, crushing, sieving, mixing secondarily, winding and forming, vulcanizing secondarily and turning. According to the rubber covered roller of the island structure, the friction coefficient and the wear resistance of the rubber covered roller can be improved effectively. Influence of the friction coefficient and the wear resistance on performance of a material is eliminated in a using process, and slip, non-uniform stress and nowear resistance and cracking phenomena are prevented.

Description

technical field [0001] The invention belongs to the technical field of rubber rollers, and in particular relates to a sea-island structure rubber roller and a preparation method thereof. Background technique [0002] A rubber roller is a roller-shaped product that uses metal or other materials as the core and is covered with a rubber layer. Cots are widely used in metallurgy, non-ferrous metal processing, chemical fiber, papermaking and other industries. With the rapid development of the manufacturing industry, various production lines have appeared in the iron and steel industry, accompanied by rubber rollers of various positions, such as pinch rollers mainly used for conveying steel plates. Users have higher requirements for their friction coefficient and wear resistance. It is used to prevent it from slipping during transportation and prolong its service life. [0003] At present, in actual operation, the following methods are often used to increase the friction coeffic...
