Abstract

The invention discloses a thermoplastic polyurethane particle which comprises the following components in parts by weight: 2-6 parts of DOTP, 0.5-1.5 parts of naphthenic oil, 2-4 parts of barium stearate, 0.1-0.3 part of UV9, 0.1-0.3 part of 1010, 1-2 parts of pigment, 30-50 parts of polyurethane foam and 10-20 parts of coarse whiting. The invention discloses a preparation method for the thermoplastic polyurethane particle. The thermoplastic polyurethane particle disclosed by the invention is characterized by little odor, light weight, environmental protection and good adhesive strength.

Description

technical field [0001] The invention relates to a thermoplastic polyurethane particle. Background technique [0002] Polyurethane granules can be used for elastic ground such as plastic runways, plastic courts, kindergarten grounds, bicycle lanes, and fitness trails. At present, most of the polyurethane granules on the market are cast-type urethane granules. The process is cumbersome, and the proportion is large (1kg per square meter per millimeter of polyurethane granules for kindergarten floors), strong odor, high cost, and low output. Contents of the invention [0003] In order to solve the above technical problems, the object of the present invention is to provide a thermoplastic polyurethane particle. [0004] In order to solve the problems of the technologies described above, the present invention adopts the following technical solutions: [0005] A thermoplastic polyurethane particle, comprising the following components by weight: [0006] DOTP 2-6 servings [0...
