Technical Field

The invention relates to the technical field of sports plastic materials, in particular to a detachable composite sports ground material.

Background

After the new national standard GB36246-2018 synthetic material surface sports ground in middle and primary schools in the existing industry is issued and implemented in 11 months in 2018, the conditions that the industrial material technology or the use requirement does not reach the standard exist, and the analysis of three general materials in the existing market has the following specific defects and shortcomings: 1. suspension type dismounting surface layer structure (finished sheet, field assembly): the product is easy to install, convenient to disassemble and assemble and good in drainage performance. The disadvantages are: firstly, the elasticity requirement can not meet the new national standard requirement, and the antiskid and wear-resistant values of the surface layer can not meet the new national standard requirement; secondly, the surface layer has no elastic plastic structure, so that the surface layer is easy to be damaged and cannot be laid on the surface layers of the runway field and the professional court in a large area; the requirement on the flatness of the base layer is high, and the fulcrum is easy to suspend and block in the air in the practical process; the connecting fastener is not firm and is easy to loosen to generate potential safety hazards; fifthly, PP chemical raw materials are synthesized, become brittle at low temperature and are easy to damage; the wear resistance is poor, the aging is easy, and the service life is short; 2. prefabricated field surface (finished coiled material, on-site bonding construction): environment protection, stable surface layer performance and standard quality. The disadvantages are: the requirement on the flatness of a foundation ground is very high, water is easy to accumulate after the foundation ground is finished, and the quality of a surface layer is affected. Secondly, the construction difficulty is high, the quality problem is easy to occur in the bending construction at the bend of the runway, and heavy objects are needed to compact the joint. Thirdly, the bottom layer adhesive is easy to age, seams or joints are easy to warp after the temperature difference is too large, local hollowing (steam effect) appears in large quantity, and the later maintenance difficulty is large. Fourthly, the surface layer has single grain, cannot be spliced and is not practical for other practical fields. The cost is high, and the manufacturing cost is high; 3. all-plastic (mixed or ventilated) playground floor (liquid AB group material, in-situ layered construction): the surface layer has better performance and the base layer has low flatness requirement. The disadvantages are: firstly, the field construction machinery and the manual work are combined, the consistency of the whole thickness is difficult to ensure, and the performance of the elastic field of the surface layer is unstable. Secondly, the gas pollution is easily generated by field construction and surface layer spraying. And thirdly, the raw materials are diluted by adding a solvent after being fed to the site, so that the environmental protection problem cannot be controlled.

The mutual comparison of above-mentioned three kinds of materials is difficult to discover, and the problem that the plastic material of motion generally faces has now to connect the fastener insecure, and easy not hard up produces the potential safety hazard, and drainage performance is not enough, and the later stage maintenance degree of difficulty is big, and surface course line is single, can't the various piece together, and site operation and surface course spraying produce gas pollution again easily, await us to solve.
