Abstract

The invention relates to a special adhesive for a hemisphere of a table tennis. The special adhesive comprises the following components in parts by weight: 3-5 parts of alpha-cyanoacrylate, 2-5 parts of vinyl imidazole, 40-50 parts of ethyl alcohol, 25-40 parts of diluent, and 0.1-0.5 part of divinyl benzene. The liquid materials of the alpha-cyanoacrylate, the vinyl imidazole and the divinyl benzene are used, the viscosity of the adhesive is reduced, and the materials are better mixed evenly, so that the dissolution and the adhesion of PVC (polyvinyl chloride) and the evaporation speed of a solvent are controlled, and the final bonding strength is high and is favorable for prolonging the service life of the table tennis.

Description

technical field [0001] The invention belongs to the field of adhesives, and in particular relates to a special adhesive for table tennis hemispheres. 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 Method, for the first time, using thermoplastic PVC as the main raw material, two ...
