Non-celluloid sheet material for environment-friendly table tennis

Abstract

The invention relates to a non-celluloid sheet material for an environment-friendly table tennis. The non-celluloid sheet material comprises components of cellulose acetate, camphor powder, dimethyl phthalate, zinc oxide whisker, liquid nylon, acetone ester, a pigment, and a solvent. The non-celluloid sheet material prepared by the formula is free of nitrocellulose and not prone to flame and combust, and therefore has excellent safety performance. The safety problem of the table tennis (including raw materials) in production, storage, transportation, and use processes is fundamentally solved. No liquid waste is discharged, and the non-celluloid sheet material has a good environmental protection property. Furthermore, the preparation technology is simple and has a short period. The prepared table tennis is high in hardness and excellent in elastic modulus. The non-celluloid sheet material not only has a mechanical property quite approximate to that of celluloid, thereby guaranteeing the kinetic characteristic of the table tennis, but also has a processing property satisfying requirements of an existing technical device for the table tennis, thereby guaranteeing a high-speed and high-efficiency manufacturing process.

Description

technical field [0001] The invention relates to a non-celluloid sheet material, in particular to an environment-friendly non-celluloid sheet material for table tennis. Background technique [0002] Traditional table tennis adopts celluloid as raw material, and the appearance of celluloid is a colored or colorless transparent or opaque flake, which is soft and elastic. Insoluble in water, benzene, toluene, soluble in ethanol, acetone, ethyl acetate. It has great tensile strength, water resistance, oil resistance and acid resistance. Because of its high hardness and modulus of elasticity, the table tennis balls made have the advantages of uniform thickness and long service life, and this material has been used until now. [0003] Celluloid flakes use dehydrated nitrocellulose as the main raw material, which is flammable and explosive, and there are great safety hazards in the storage and transportation of the raw material stage, the production stage, and after being made int...

Problems solved by technology

[0003] Celluloid flakes use dehydrated nitrocellulose as the main raw material, which is flammable and explosive, and there are great safety hazards in the storage and transportation of the raw material stage, the production stage, and after being made into table tennis products, its , There are also flammable hidden dangers in the transportation process

In the manufacturing process, a large amount of solvents are used, which will bring harm to the environment, and the cost is high
