Problems solved by technology

However, since waste tire rubber granules are made of waste rubber, although it can save costs and recycle waste rubber resources, there are the following problems: 1) The resilience of waste tire rubber granules is insufficient, the impact resistance is general, and the weather resistance is not good. Good, toughness and tensile strength are not high enough; 2) The self-adhesiveness and inter-adhesiveness of waste tire rubber particles are poor, and the adhesion between the adhesive and the adhesive is weak, not easy to bond, and prone to threshing; 3) Waste tires Rubber granules contain a large amount of aromat

Example Embodiment

[0061] The preparation method of the above-mentioned breathable plastic track includes the following steps:

[0062] 1) Clean the surface of the concrete base layer, then pickling, water washing and drying;

[0063] 2) Coat the adhesive on the concrete base layer to form a bonding layer;

[0064] 3) Premix the TPEE particles, EPDM particles and one-component polyurethane adhesive uniformly and then lay them on the bonding layer, dry to form an elastic layer;

[0065] 4) First mix polyurethane resin, fillers, pigments, wetting and dispersing agents, antioxidants, bactericidal and antifungal agents and ultraviolet absorbers, and then add EPDM particles, mix well, and then lay the obtained premix on the elastic layer , Dry to form a polyurethane surface layer to obtain a breathable plastic track.

Abstract

The invention discloses a permeable plastic runway and a preparing method thereof. The permeable plastic runway comprises a concrete foundation layer, a bonding layer, an elastic layer and a polyurethane surface layer from bottom to top in sequence; TPEE particles are added in the elastic layer. The preparing method comprises the steps of 1, pretreating the surface of the concrete foundation layer, 2, applying the bonding layer, 3, laying the elastic layer, and 4, laying the polyurethane surface layer. The permeable plastic runway has the advantages of being moderate in elasticity, good in rebound resilience, high in toughness and stretching strength, good in air permeability, high in stability and long in service life, the preparing technology is simple, and the permeable plastic runway can be widely applied to sites such as schools, gymnasiums, residential quarters and parks.

Description

technical field [0001] The invention relates to a breathable plastic runway and a preparation method thereof. Background technique [0002] Sports tracks are generally set up in schools, gymnasiums, residential areas, parks and other places. Traditional sports tracks are cement tracks, cinder tracks, etc., and there are many problems. At present, most sports tracks are plastic tracks, which have the characteristics of good flatness, high compressive strength, moderate hardness and elasticity, and stable physical properties. Athletes' sports injuries are internationally recognized as the best outdoor sports venues. [0003] The paving material for the plastic runway is composed of polyurethane prepolymer, mixed polyether, waste tire rubber, EPDM rubber particles or PU particles, pigments, additives, fillers, etc. A large number of waste tire rubber particles (black rubber particles) are added to the elastic layer of the plastic runway, which is mainly used as an elastic mat...
