Embodiment Construction

[0076] Attached below figure 1 , tables and examples, the present invention is described in detail.

[0077] Environmentally-friendly one-component water-cured plastic track materials. Water-cured materials can be used to adjust the curing time and flexibility of the material. Compared with the current two-component oily materials on the market, water-cured one-component materials are more environmentally friendly and have lower tensile strength. and higher elongation at break.

[0078] The self-knotting pattern refers to the phenomenon that the non-slip uneven surface of the plastic runway uses special polyurethane pure glue and a polyurethane copolymer formed through physical reaction to automatically generate uneven unevenness in the surface knot state. The texture formed by the self-knotting pattern reaches a certain friction coefficient, meets the anti-wet and slippery indicators, does not drop grains, does not have broken lines, does not require special manual maintenan...

Abstract

The invention relates to the field of plastic runways, in particular to a mixed plastic runway and a construction method thereof. According to the main points of the technical scheme, the mixed plastic runway comprises a pre-pavement layer, a base layer, a reinforcing layer and a surface layer in sequence; the pre-pavement layer is prepared from the following components in parts by weight: 25 to 30 parts of coal gangue, 15 to 20 parts of quartz sand, 3 to 5 parts of coal ash, 3 to 5 parts of talcum powder and 3 to 5 parts of bentonite; the above components are paved on a ground surface to formthe pre-pavement layer after being sintered and crushed; the base layer is prepared from the following raw materials: a mixed polyurethane adhesive, a catalyst, sodium carbonate and rubber particles;holes are preserved in the base layer; the holes are filled with the sodium carbonate; the reinforcing layer is prepared from the following raw materials: the rubber particles, an environment-friendly single-component water-cured plastic runway material and the sodium carbonate; the surface layer is prepared from the following raw materials: EPDM particles, self-setting varnished finish, the quartz sand and the sodium carbonate. The sodium carbonate is dissolved in water easily; water seepage holes are formed in the plastic runway after the sodium carbonate is dissolved, so that a water seepage function of the runway is enhanced.

Description

technical field [0001] The invention relates to the field of plastic runways, more specifically, it relates to a hybrid plastic runway and a construction 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 floor material. Due to it...
