Abstract

The invention relates to the technical field of rubber, in particular to an impact-resistant rubber material for a baseball center. The impact-resistant rubber material is prepared from the raw materials in parts by weight: 50-65 parts of isoprene rubber, 25-40 parts of butadiene rubber, 45-55 parts of coumarone resin, 2-5 parts of alkyd resin, 3-7 parts of polytetrafluoroethylene resin, 13-27 parts of polyester staple fibers, 6-10 parts of nano-sized magnesium hydroxide, 1.2-3.5 parts of wood fiber powder, 1.3-2.7 parts of jade powder, 0.6-0.9 part of zinc borate, 1-3 parts of clay, and 5-10parts of an additive. The impact-resistant rubber material has excellent elasticity and impact resistance and the low weight.

Description

technical field [0001] The invention relates to the technical field of rubber, in particular to an impact-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 elasticity and impact 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 the highly elastic impact-resistant rubber material. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes an impact-resistant rubber material for a baseball core. The present invention has excellent elasticity and impact resistance as well as light weight. [0004] A kind of impact-resistant rubber material for baseball...
