The table edge surround material prepared by the invention has excellent wear resistance, strength and toughness.

Description

technical field [0001] The invention belongs to the technical field of composite material preparation, and in particular relates to a table edge surrounding material and a preparation method thereof. Background technique [0002] At present, because the edge of the wooden table is too hard, it is very easy to be injured by adults, especially the more active children. In order to reduce the impact force, many table edges are currently equipped with plastic edging. However, the current table edge surround materials generally use thermoplastic polyurethane elastomers for hemming, and the wear resistance, strength and toughness of ordinary thermoplastic polyurethane elastomers cannot meet the needs of actual use. [0003] Chinese patent application document "A wear-resistant TPU material (application number: 201711016318.9)" discloses a wear-resistant TPU material, the raw materials and raw material weight percentages are as follows: TPU40-50%, rubber 0.1-1%, 0.1-3% polytetrafl...
