Problems solved by technology

But adopting celluloid to be raw material to make highly elastic table tennis has following drawbacks: celluloid material is to be main raw material with the nitrocellulose of dehydration, and it is inflammable and explosive, and there is bigger safety in its storage in raw material stage, production stage, transportation process hidden dangers, and after being made into table tennis products, there are also hidden dangers of flammability during storage and transportation; and for safety, nitrocellulose needs to be added with water during transportation, and needs to be dehydrated during use. There is a large amount of waste liquid discharged, which will It brings harm to the environment and is not environmentally friendly; in addition, its production process is complicated and the production cycle is long

Abstract

The invention relates to a polymer composition for manufacturing a high-elasticity table tennis ball. The polymer composition is prepared from the following components in parts by weight: 110-150 parts of polyethylene, 10-20 parts of vinyl imidazole-acrylonitrile copolymer, 0.5-2.5 parts of a heat stabilizer, 1-5 parts of a lubricant, 5-8 parts of a strengthening and toughening agent, 0.1-0.2 part of titanium dioxide powder and 0.1-0.2 part of an antioxidant. According to the polymer composition, by adopting the raw materials including the vinyl imidazole-acrylonitrile copolymer, the heat stabilizer, the lubricant, the strengthening and toughening agent, the titanium dioxide powder, the antioxidant and the like according to the ratio, celluloid is prevented from being used, and the polymer composition is low in cost, high in hardness, excellent in elastic modulus and good in eccentricity and can meet environment-friendly table tennis ball used materials needed by a table tennis official ball.

Description

technical field [0001] The invention belongs to the field of polymer materials, in particular to a polymer composition used for making high-elastic table tennis balls. Background technique [0002] Since the 1930s, celluloid has been used as a raw material to prepare table tennis balls. Due to its high hardness and elastic modulus, the table tennis balls produced have the advantages of uniform thickness and long service life, and this material has been used until now. . But adopting celluloid to be raw material to make highly elastic table tennis has following drawbacks: celluloid material is to be main raw material with the nitrocellulose of dehydration, and it is inflammable and explosive, and there is bigger safety in its storage in raw material stage, production stage, transportation process hidden dangers, and after being made into table tennis products, there are also hidden dangers of flammability during storage and transportation; and for safety, nitrocellulose need...
