Durable antiskid plastic runway and preparation method thereof

Abstract

The invention discloses a durable anti-skid plastic runway and a preparation method thereof, and belongs to the field of plastic runways. The durable anti-skid plastic runway comprises two wrapping layers, a plastic site elastic layer and a plastic site anti-skid surface layer, wherein the plastic site elastic layer is located between the wrapping layers on the two sides, and the thickness of the plastic site elastic layer is 8 mm. According to the scheme, multiple layers of composite materials are adopted for preparing the plastic runway, permeation type bonding is adopted between the layers, firmness is achieved, plastic stripping is not prone to occur, the problems of bulging and delaminating of a plastic site are effectively solved through macromolecule elastic fibers, a first layer of macromolecule airtight film prevents underground moisture from evaporating upwards, and meanwhile, the bonding degree of the plastic site and a foundation is increased, the plastic site elastic layer effectively increases the elasticity and flexibility of the plastic site, a second layer of macromolecule airtight film can prevent rainwater from infiltrating downwards, rapid drying of the site after raining is facilitated, and the plastic site anti-skid surface layer plays a role in wear resistance, skid resistance and durability.

Description

technical field [0001] The invention relates to the field of plastic running tracks, and more specifically relates to a durable non-slip plastic running track and a preparation method thereof. Background technique [0002] The plastic track is also called the all-weather track and field track. It is composed of polyurethane prepolymer, mixed polyether, waste tire rubber, EPDM rubber particles or PU particles, pigments, additives, and fillers. The plastic runway has the characteristics of good flatness, high compressive strength, appropriate hardness and elasticity, and stable physical properties. It is conducive to athletes' speed and technical performance, effectively improving sports performance and reducing the rate of falls. The plastic runway is composed of polyurethane rubber and other materials. It has certain elasticity and color, and has certain anti-ultraviolet ability and aging resistance. It is internationally recognized as the best all-weather outdoor sports flo...

AI Technical Summary

Problems solved by technology

[0004] At present, the pavement layer used in most plastic runways is only 2-3 layers. Not only is the pavement layer not firmly connected to the ground foundation, but also there are drums and delaminations between the layers due to bonding. , the service life is relatively short, and even some plastic runway anti-slip surfaces are too rough due to excessive friction resistance, which can easily cause athletes to fall and scratch their skin
