Material for table tennis and production method thereof

Abstract

The invention discloses a material for a pingpong ball and a production method of the material for the pingpong ball. The material for the pingpong ball comprises the following raw materials in parts by weight: 50-100 parts of ABS resin, 3-15 parts of K glue, 0.5-10 parts of N,N'-ethylene bisstearamide, 2-12 parts of a processing aid, 3-15 parts of camphor, 0.005-0.5 part of an antioxygen, and 0.005-0.5 part of toner. The production method of the pingpong ball by using ABS as the main raw material has the advantages that after an internal half ball and an external half ball are adhered, the waist of the pingpong ball is not protruded, and after ball expansion, the grinding time is greatly shortened; and an injection molding point of the internal half ball and the external half ball is positioned on the inner side of the center of the top, marks remaining on the top due to grinding of the injection molding point are eliminated, the thickness of the top is increased, so that the strengths of the top and the waist of the pingpong ball are improved, and the anti-hitting ability of the pingpong ball is improved.

Description

technical field [0001] The invention relates to the technical field of table tennis manufacturing, in particular to a table tennis material with ABS (acrylonitrile-butadiene-styrene) as the main raw material and a production method thereof. Background technique [0002] Throughout the development history of table tennis, although table tennis technology has undergone earth-shaking changes, table tennis made of celluloid has been used so far because of its excellent performance. However, table tennis balls made of celluloid materials are increasingly showing great problems. One is that the celluloid material itself is extremely easy to burn, and there are great safety hazards in the production, storage and transportation of table tennis balls. The second is that the traditional table tennis production process is relatively backward, and produces a large amount of waste liquid, waste gas, etc., which has caused great pollution to the environment. [0003] In the past ten year...

AI Technical Summary

Problems solved by technology

Patent Publication No. CN103172910A discloses a table tennis ball made of cellulose diacetate as the main raw material. The main technical indicators are very close to those of celluloid table tennis balls. The production process completely follows the celluloid table tennis production process

Patent Publication No. CN102896788A discloses a method for producing table tennis balls by injection molding with butadiene-styrene copolymer and acrylonitrile-butadiene-styrene copolymer as main raw materials. From the point of view of its matching ratio, it does not meet the soft and rigid characteristics of table tennis. At the same time, the key technology of the injection molding process is not disclosed at all.

Patent Publication No. CN105385095A discloses a table tennis material similar to the above patent, which cannot meet the basic requirements that table tennis balls should have high impact strength, and the material processing performance is extremely poor

[0004] Patent Publication No. CN103819845A discloses an environmentally friendly thermoplastic PVC table tennis material and a method for preparing table tennis balls. The method adopts injection molding technology to process two male and female hemispheres of table tennis balls. After the ball is expanded, it needs to be polished for a long time, and the injection point is on the circumference of the waist, which will have an adverse effect on the bonding of the two hemispheres

[0005] In the specific production process of the above-mentioned disclosed patented technologies, 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. The 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 be suitable for the existing process equipment of table tennis balls in terms of processing performance. requirements to ensure that the manufacturing process can be carried out at high speed and efficiently
