Abstract

The invention discloses a special adhesive for a thermoplastic PVC table tennis. The special adhesive mainly comprises a raw material having dissolving and adhering effects on PVC, a diluent and a stabilizer as auxiliary materials. The table tennis finished product adhered by virtue of the special adhesive has no white flower and traces; mechanical properties such as hardness and strike resistance of the table tennis adhering part have no difference from those of other parts and the special adhesive achieves the same technical standard as celluloid.

Description

technical field [0001] The invention relates to a special adhesive for PVC table tennis. Background technique [0002] Since the 1930s, celluloid has been used as the main material for making table tennis balls. Celluloid is flammable and explosive, and there are great safety hazards in the process of production, transportation and storage. It has become a consensus in the table tennis industry to use non-celluloid raw materials to make table tennis balls and maintain the original elasticity, hardness and impact resistance. Existing some patents disclose the table tennis (CN101272830A, CN101585224, CN102838782A) with non-celluloid as raw material, the environmentally friendly thermoplastic PVC table tennis materials disclosed by Jiangnan University and Jiangyin Boer Plastic Co., Ltd. and the method of preparing table tennis with it The method (CN103819845A) uses thermoplastic PVC as the main raw material for the first time, and with the method of injection molding, two tab...
