Problems solved by technology

[0002] The synthetic materials of TPU particles generally have poor wear resistance, and the overall impact strength and adhesion are not good. The synthetic materials of TPU particles are generally used to pave the surface of the runway. Due to the high frequency of use of the runway, TPU particles The wear resistance of synthetic materials is very important. When TPU particles are spread on the surface of the runway base, the density of TPU particles is not high, which is not conducive to long-term use

Abstract

The invention discloses a synthetic formula and a construction method of environment-friendly TPU particles. According to the construction method, synthetic materials of the environment-friendly TPU particles are mixed to be prepared into particles; the particles are spread on a foundation of a runway for two times using a paver. The synthetic materials of the environment-friendly TPU particles are environment-friendly materials, particle wear resistance is improved, particle impact strength and toughness are improved, particle water absorption rate and oil absorption value are reduced, and the influence of water or oil stains on the particles can be reduced; the service life of the particles is prolonged, a tackifier is added, the adhesiveness of the particles is improved, and the phenomenon that a part of the particles are stripped from the foundation of the runway is avoided.

Description

technical field [0001] The invention relates to the related fields of building construction, in particular to a synthetic formula and a construction method of environmentally friendly TPU particles. Background technique [0002] The synthetic materials of TPU particles generally have poor wear resistance, and the overall impact strength and adhesion are not good. The synthetic materials of TPU particles are generally used to pave the surface of the runway. Due to the high frequency of use of the runway, TPU particles The wear resistance of synthetic materials is very important. When TPU particles are spread on the surface of the runway base, the density of TPU particles is not high, which is not conducive to people's long-term use. Contents of the invention [0003] The object of the present invention is to provide a synthetic formula and construction method of environmentally friendly TPU particles to solve the problems raised in the above-mentioned background technology....
