Problems solved by technology

[0002] At present, the core material of a solid soft baseball is generally synthetic rubber, and the toughness and wear resistance of the synthetic rubber in the prior art cannot meet the needs of actual use, making the quality and quality of the baseball far from reaching the market. Requirements, so there is an urgent need to develop a high toughness wear-resistant rubber material for baseball cores to solve the problems in the prior art

Abstract

The invention relates to the technical field of rubber, in particular to a wear-resistant rubber material for baseball cores, which is made with, by weight, 70-88 parts of nitrile butadiene rubber, 28-38 parts of urea resin, 40-65 parts of modified furfural resin, 10-14 parts of silicon dioxide, 2-6.5 parts of calcium sulfate whiskers, 3-10 parts of nano carbon black, 3.2-5.7 parts of bamboo fiber, 0.5-2.5 parts of trioctyl trimellitate, 3-5 parts of liquid paraffin, 1-3.7 parts of aluminum polyphosphate, 0.3-0.8 part of dicumyl peroxide, 1-2 parts of a rare-earth stabilizer, 1-2 parts of glycerol, 1.5-3.5 parts of a curing agent, and 0.2-0.5 part of an antioxidant. The wear-resistant rubber material for baseball cores has high toughness, good corrosion resistance and good wear resistance.

Description

technical field [0001] The invention relates to the technical field of rubber, in particular to a wear-resistant rubber material for a baseball core. Background technique [0002] At present, the core material of a solid soft baseball is generally synthetic rubber, and the toughness and wear resistance of the synthetic rubber in the prior art cannot meet the needs of actual use, making the quality and quality of the baseball far from reaching the market. Requirement, therefore urgently need to develop a kind of baseball core to solve the problem in the prior art with high tenacity wear-resistant rubber material. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a wear-resistant rubber material for a baseball core. The invention has high toughness and good corrosion resistance and wear resistance. [0004] A wear-resistant rubber material for a baseball core proposed by the present inve...
