Nano-modified polymer material for table tennis and manufacturing method thereof

Abstract

The invention discloses a nano-modified polymer material for table tennis. The nano-modified polymer material comprises, by weight, 50-75% of poly(butylene succinate) or polylactic acid; 3-7% of lignocelluloses, 1-2% of plant fibre, 15-18% of a plasticizer and 0.5-3% of titanium dioxide and nano-silica dioxide material. A manufacturing method of the nano-modified polymer material comprises the following steps: Step 1, mixing raw materials while adding 0.5% of a mixture of polyvinyl chloride and polypropylene nano-powders, and stirring for 1-1.5 h; Step 2, extruding by an extruder to obtain a sheet material; and Step 3, cutting the sheet material by a cutting machine into small pieces for manufacturing of table tennis. In comparison with a celluloid material, the nano-modified polymer material for table tennis is safe in production, is biodegradable and causes little environmental pollution. Meanwhile, table tennis prepared from the nano-modified polymer material has excellent performance indexes, and part of the performance exceeds performance of table tennis prepared from celluloid.

Description

technical field [0001] The invention specifically relates to the technical field of sporting goods, in particular to a nano-modified polymer material for table tennis and a manufacturing method thereof. Background technique [0002] Most table tennis balls in the prior art are manufactured using celluloid as a raw material. Although the table tennis balls made of celluloid have excellent performance, celluloid is flammable and explosive, difficult to transport and produce, and has a low safety factor. At the same time, its manufacturing cost is relatively high. , the process is more complicated, and the harm to the environment is greater. There are also a number of new materials that replace celluloid in the market, but these new materials generally do not meet the performance level of celluloid, and the manufacturing cost remains high. Materials with low environmental hazards and performance comparable to or exceeding that of celluloid are the difficulties that all personn...

At the same time, its manufacturing cost is relatively high. , the process is more complicated, and the harm to the environment is greater

There are also a number of new materials that replace celluloid in the market, but these new materials generally do not meet the performance level of celluloid, and the manufacturing cost remains high. Materials with low environmental hazards and performance comparable to or exceeding that of celluloid are the difficulties that all personnel in the field of table tennis manufacturing need to overcome.
