Problems solved by technology

[0004] There are many types of hybrid runways on the market. Among them, the all-plastic self-knotting track is superior to similar products in terms of runway performance and follow-up maintenance. However, the bottom construction of the all-plastic self-knotting track has high requirements for the foundation and the environment, and there are too many construction procedures. The process requirements are high, the time required is long, and the existing self-knotting sports venues are not flexible enough to meet people's needs well

Embodiment 1

[0025] The construction method of the self-knotting plastic runway with mixed primer is as follows:

[0026] 1) Plain land treatment: Clean up the site, sprinkle water on the whole site and level the test site. After testing the water for one hour, mark the place where the ground is sunken more than 3mm with a marker pen, and use EPDM particles, 40- The mass ratio of 70-mesh quartz sand and polyurethane glue is 1:1:0.04, and then add an appropriate amount of thinner to stir evenly and adjust to a suitable construction consistency. Use a ruler or a scraper to level the water. If the water depth exceeds 5mm, apply EPDM particles and polyurethane glue at a mass ratio of 1:0.04 and apply a thin layer on the water accumulation, then use waterproof primer (WD) and 40-70 mesh quartz sand to apply waterproof primer: The mass ratio of 40-70 mesh quartz sand is 1:6, mix evenly, spread it evenly in the place where the water accumulates and compact it, and fill up the depressions in the f...

[0034] The construction method of the self-knotting plastic runway with mixed primer is as follows:

[0035] 1) Plain land treatment: Clean up the site, sprinkle water on the whole site and level the test site. After testing the water for one hour, mark the place where the ground is sunken more than 3mm with a marker pen, and use EPDM particles, 40- The mass ratio of 70-mesh quartz sand and polyurethane glue is 1:1:0.06, and an appropriate amount of diluent is added to stir evenly and adjust to a suitable construction consistency. Use a ruler or a scraper to level the water. If the water depth exceeds 5mm, apply EPDM particles and polyurethane glue at a mass ratio of 1:0.06 and apply a thin layer on the water accumulation, and then use waterproof primer (WD) and 40-70 mesh quartz sand to apply waterproof primer: The mass ratio of 40-70 mesh quartz sand is 1:8, mix evenly, spread it evenly in the place where the water accumulates and compact it, fill up the depressions in the f...

[0042] The construction method of the self-knotting plastic runway with mixed primer is as follows:

[0043] 1) Plain land treatment: Clean up the site, sprinkle water on the whole site and level the test site. After testing the water for one hour, mark the place where the ground is sunken more than 3mm with a marker pen, and use EPDM particles, 40- The mass ratio of 70-mesh quartz sand and polyurethane glue is 1:1:0.05, and an appropriate amount of thinner is added to stir evenly and adjust to a suitable construction consistency. Use a ruler or a scraper to level the water. If the water depth exceeds 5mm, apply EPDM particles and polyurethane glue at a mass ratio of 1:0.05 and apply a thin layer to the water accumulation, and then use waterproof primer (WD) and 40-70 mesh quartz sand to apply waterproof primer: The mass ratio of 40-70 mesh quartz sand is 1:7, mix evenly, spread it evenly in the place where the water accumulates and compact it, fill up the depressions in the f...

Abstract

The invention discloses a mixed primer self-corrugated plastic runway, comprising a bottom layer and a surface layer, wherein the bottom layer is formed by mixing ETPU, polyurethane glue and EPDM particles according to a mass ratio of 25-30: 3.5-4.0: 1, and the thickness is 8-10mm; The surface layer is composed of PU gum and red gum powder, 70-100-mesh quartz sand is spray and laid according to that mass ratio of 1: 0.3 to 0.6: 0.1 to 0.3, and the thickness is 3.0 to 6.0 mm. The construction method is disclosed and includes the steps: 1) treating a land; 2) spreading that bottom layer: mix andstirring ETPU, polyurethane glue and EPDM particles, and then spreading the ETPU, polyurethane glue and EPDM particles, wherein the thickness is 8-10mm, and solidify; 3) paving layer: mixing and stirring the PU surface glue, red glue powder and quartz sand, and the thickness is 3.0-6.0 mm; and 4) mixing and stirring the ETPU, polyurethane glue and EPDM particles, and solidifying.

Description

technical field [0001] The invention belongs to the technical field of sports floor, and in particular relates to a mixed-type bottom glue self-knotting plastic runway and a construction method thereof. Background technique [0002] With the continuous and rapid development of the economy and the continuous improvement of people's living standards, it is becoming more and more common to use plastic to rebuild the ground floor of sports venues. At present, polyurethane plastic sites are mainly composed of polyurethane prepolymer, mixed polyether, waste tire rubber, EPDM (ethylene propylene diene monomer) rubber particles or PU (polyurethane material) particles, pigments, additives, fillers, etc. , and its raw materials are mainly divided into two types: diphenylmethane diisocyanate (MDI) and toluene diisocyanate (TDI). The ETPU particle (thermoplastic polyurethane, commonly known as popcorn) material has the advantages of lightness, softness and good elasticity, and can main...
