Problems solved by technology

Nano-calcium carbonate has a large specific surface area. After compounding with rubber, a strong interfacial interaction occurs between the nano-inorganic particles and the rubber matrix, which makes the rigidity, thermal stability, and dimensional stability of the nano-inorganic particles compatible with the toughness and processing performance of the

Abstract

The invention provides a modified rubber V belt made of nano-material, which comprises rubber matrix, vulcanizing agent, accelerators, stearic acid, antioxidant, softener and carbon black, and comprises further nano-zinc oxide and nano-calcium carbonate. The product is made with 2.5 to 10 portions of the nano-zinc oxide and 5 to 50 portions of nano-calcium carbonate on the basis of 100 portions of rubber matrix. Mechanical property, wear resistance, compression set and tearing property of the rubber can be improved obviously and the performance of the finished product is improved with indirect zinc oxide being replaced by the nano-zinc oxide, soft semi reinforcing carbon black being replaced by the nano-calcium carbonate.

Description

Technical field: [0001] The invention belongs to the technical field of development and modification of rubber V-belts, in particular to a nano-material modified rubber V-belt and a manufacturing method thereof. Background technique: [0002] Zinc oxide has been widely used as a vulcanization activator in rubber. During the vulcanization process, zinc oxide can react with accelerators, vulcanizing agents, stearic acid, rubber macromolecular chains and corresponding intermediate products. At present, indirect zinc oxide is widely used in the rubber industry, with a purity of about 99.7% and a particle size of 0.10-0.27um. Based on 100 parts of raw rubber, the traditional dosage of zinc oxide is 5 parts. However, when the amount of zinc oxide is 3 to 5 parts, the vulcanization rate will slow down and the physical and mechanical properties will decrease. This is due to the large particle size, small specific surface area and low activity of ordinary zinc oxide. Invention co...
