Abstract

The invention discloses a rubber material of a baseball core. The rubber material is prepared from the following raw materials in parts by weight: 60 to 80 parts of natural rubber, 20 to 40 parts of isoprene rubber, 50 to 70 parts of filler, 1 to 2 parts of tributyl citrate, 1 to 2 parts of epoxy acetyl methyl linoleate, 40 to 50 parts of nanometer magnesium hydroxide, 10 to 15 parts of zinc borate, 1 to 3 parts of Si69, 1 to 2 parts of sulfur, 0. 5 to 0.7 part of dicumyl peroxide, 0.1 to 0.3 part of accelerant D, 0.2 to 0.3 part of accelerant TMTD, 4 to 6 parts of Ca / Zn (calcium / zinc) composite stabilizer, 0.4 to 0.6 part of anti-aging agent, 0.2 to 0.4 part of antioxidant, and 2 to 4 parts of polyethylene wax, wherein the filler comprises modified montmorillonite, hollow glass microbeads, and modified microcrystalline cellulose. The rubber material has the advantages that the anti-impact property, toughness and elasticity are good, the weight is light, and the durability and ball striking effect are better.

Description

technical field [0001] The invention relates to the technical field of rubber, in particular to a rubber material for a baseball core. Background technique [0002] Softball is designed to promote baseball and softball. It is similar in nature to baseball and softball. Its competitiveness and fun can be compared with regular baseball and softball. It is characterized by simplified game rules, low requirements for venue conditions, and the number of people who can participate Many, safe, very suitable for carrying out on campus, from which you can experience the fun of baseball and softball. [0003] The baseball used in soft baseball is divided into hollow ball and solid ball. The core material of solid ball is generally cork or synthetic rubber. Cork is the bark of the oak tree. The main component is cork fiber. Its source is limited, and a large amount of use will consume natural resources. Moreover, the baseball made of cork is not stable in coagulation during molding, a...
