Problems solved by technology

[0004] In the specific production process of the above-mentioned disclosed patented technology, either the performance of the table tennis ball is difficult to reach the standard or the production efficiency cannot be compared with the existing technology. Ball technology can replace celluloid as a new material for making table tennis balls. This material must be very close to celluloid in terms of mechanical properties to ensure the sports characteristics of table tennis balls, and must also meet the requirements of existing table tennis technology equipment in terms of processing performance. To ensure that the manufacturing process can be carried out quickly and efficiently

Abstract

The invention discloses a polyvinyl chloride material for manufacturing ping-pong balls and a preparation method thereof. The polyvinyl chloride material comprises the following raw materials in parts by weight: 50-150 parts of polyvinyl chloride, 5-20 parts of nano calcium carbonate, 6-22 parts of solid plasticizer, 3-12 parts of Ca-Zn composite stabilizer, 10-30 parts of flexibilizer and 0.01-0.1 part of pigment. The polyvinyl chloride material is substantially approximate to celluloid ping-pong balls in terms of mechanical properties, particularly of leaping ability and strike resistance, and is also substantially approximate to the celluloid ping-pong balls in terms of appearance and ball striking sense.

Description

technical field [0001] The invention relates to the technical field of table tennis manufacturing, in particular to a polyvinyl chloride material used for manufacturing table tennis and a preparation method thereof. Background technique [0002] Since 1935, the hard ball made of celluloid as the main raw material has been the official game ball of table tennis. However, there are many problems in the manufacture, storage and transportation of celluloid table tennis balls. Mainly: (1) long production cycle and high cost; (2) serious environmental pollution; (3) great potential safety hazards. [0003] Both at home and abroad have been devoting themselves to the research and development of non-celluloid table tennis materials and table tennis manufacturing technology thereof. Chinese patent 90103206.9 discloses a modified polystyrene as the main body, and then adds auxiliary materials such as plasticizers to manufacture table tennis balls by means of vacuum suction; Chinese ...
