Problems solved by technology

[0004] There are many defects in the traditional paving method: because the paving of the paving materials on the entire runway is completed in blocks, it is difficult to make the whole site flat and beautiful, especially the joints between two adjacent blocks are more obvious. At the same time, During the construction process, due to problems such as air bubbles and delamination, it is impossible to lay directly on wet ground and cement ground. In addition, it is difficult to control the spraying time of anti-skid rubber particles. Weak bond

Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0022] Please refer to the attached figure 1 , 2 , are schematic diagrams of the construction process of cement-based and asphalt-based plastic runways, respectively. The difference between the two construction methods lies in the first half of the ground repair, maintenance and primer (PU glue) coating process, and the second half of the primer coating, surface glue coating, granulation and scribing processes are basically the same.

[0023] Such as figure 1 As shown, when paving a runway on a cement floor, first establish the construction scope, calculate the paving area and the amount of materials used, and then carry out road surface maintenance such as crack filling. It is necessary to ensure that the dryness of the ground meets the requirements (below moisture content %) If necessary, apply primer and then cure for 1-2 hours.

[0024] Such as ...

Abstract

A method for paving plastic race track includes such steps as proportioning raw material, cleaning foundation, coating prime paint or pure PU size, spreading base plastics, spreading surface plastic,spraying antiskid plastic particles, recovering excess plastic particles, and drawing lines. Its advantages are uniform thickness, no seam and reflection, high antiwear nature, and high surface quality.

Description

technical field [0001] The invention relates to a paving construction method for a plastic runway. Background technique [0002] The international standard sports track mainly includes polyurethane (PU), EPDM, neoprene, PP glue and other types. At this stage, polyurethane (PU) material is still the most widely used as the main raw material, and curing agent and other auxiliary materials are added at the same time. Form a mixed glue. At present, the method of laying plastic runways at home and abroad is: firstly divide the runway paving area, then spread the primer and surface glue in blocks, then evenly spray anti-skid rubber particles, and finally recycle excess anti-skid rubber particles and draw runway lines. [0003] Wherein, the main components of the primer and the surface glue are polyurethane (PU resin), which are mixed with different components such as main agent and curing agent. The main difference is that the primer is also mixed with a certain proportion (usual...
