Construction method of mixed plastic runway

Abstract

The invention discloses a construction method of a mixed type plastic runway, belongs to the technical field of plastic runways, and solves technical problems that in the prior art, a construction process of the mixed type plastic runway is complex, and a content of harmful chemical substances of the laid mixed type plastic runway is high. The construction method comprises the following steps: S1,mixing primer raw materials, uniformly stirring, adding regenerated rubber particles, adding a proper amount of a catalyst, and paving a primer layer; S2, trimming and defoaming the primer layer; S3,laying an anti-skid layer, specifically, after a bottom glue layer is cured, laying a glue solution formed by adding the catalyst into a surface glue raw material and stirring on the bottom glue layer, and then throwing and scattering polyurethane red particles; and S4, spraying a particle protective layer: after the particle layer is completely cured, spraying the particle protective layer. Theconstruction method has advantages that a construction process is simple, the content of harmful chemical substances in the laid mixed plastic runway is low, and a service life of the runway is long.

Description

technical field [0001] The invention relates to the technical field of plastic runways, more specifically, it relates to a construction method of a hybrid plastic runway. Background technique [0002] The hybrid plastic runway is a kind of runway material, which adopts a mixed structure. The surface layer is PU granules or EPDM weather-resistant and environmentally friendly colored granules. The matrix is ​​all PU mixed with some rubber granules. The standard thickness of the hybrid plastic runway stipulated by international competition standards is 13mm. [0003] For the construction of the hybrid plastic runway, the construction process is different according to the raw materials of the plastic runway. The invention patent with the authorized announcement number 108193578B discloses a hybrid plastic runway and its construction method. The construction method of the plastic runway includes: S1. Laying the pre-laying layer: Grinding the raw materials of the pre-laying layer...

AI Technical Summary

Problems solved by technology

[0005] In the construction process of the above-mentioned hybrid plastic runway, there are the following problems: firstly, there are many laying processes and the process is complicated; secondly, the service life of the hybrid plastic runway obtained by laying is about 5 years; and the service life of the hybrid plastic runway obtained by laying In the chemical performance test, although all the indicators meet the standards, the content of harmful chemical substances is relatively high
