Fig. 1 is the structural representation of full-plastic plastic cement race track of the present utility model；

Fig. 2 is the top view of full-plastic plastic cement race track of the present utility model.

Embodiment

Preferred embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings, so that the advantages of the utility model It can be easier to be readily appreciated by one skilled in the art with feature, it is apparent clear and definite so as to be made to the scope of protection of the utility model Define.

Refering to shown in Fig. 1-2, full-plastic plastic cement race track of the present utility model, it includes：

Elastic layer 1 on the ground and the surface layer 2 for being arranged on the upper surface of elastic layer 1 are set, and elastic layer 1 is including from top to bottom Buffer layer 11, cushion 12 and the supporting layer 13 set gradually, buffer layer 11 include the He of buffer layer body 111 of integral molding Multiple damping projections 112, damping projection 112 are spaced apart and arranged in the lower surface of buffer layer body 111, and cushion 12 includes one The cushion body 121 and multiple buffer grooves 122 of formula shaping, buffer groove 122 are engaged with damping projection 112, cushion 12 lower surface fits with supporting layer 13, and surface layer 2 includes surface layer body 21 and skid resistant course 22, surface layer body 21 and damping The upper surface of layer 11 fits, and skid resistant course 22 is arranged on the upper surface of surface layer body 21.In the present embodiment, elastic layer 1 and surface layer 2 Formed using first group of material and second group of material polyurethane PU coating, wherein, the proportioning of first group of material is：70-80% polyethers is more First alcohol and 20-30% isocyanates, the proportioning of second group of material are：3-10%1000 molecular weight polyether polyols, 5-12%2000 Molecular weight polyether polyol, 3-12%3000 molecular weight polyether polyols, 3-5%300 molecular weight polyether polyols, 4-7% are handed over Join agent, 25-40% inorganic fillers, 1-3% levelling agents, 1-3% defoamers, 5-10% environmental-friendly pigments, 2-3% antiaging agents, 2- 3% ultraviolet-resistant absorbent, 18-25% environment-friendly plasticizers, 2-5% anti-settling agents and 5-8% foamed balls.

The utility model replaces the rubber in conventional plastic runway bottom resilient layer and surface spray plane by full-plastic group material Black particle, it is difficult that the control feature of environmental protection and malicious runway constantly take place frequently to solve the problems, such as the complicated black particle in source, reduce lead, The index exceeding standard phenomenon such as mercury, polycyclic aromatic hydrocarbon, improve the physical and mental health of students；Meanwhile pass through buffer layer 11, the and of cushion 12 Supporting layer 13, and buffer groove 122 and the ingenious cooperation of damping projection 112, elasticity and the stretching for enhancing plastic cement race track are strong Degree, impact absorbing rate more than 50% and elongation rate of tensile failure are improved, reduce injury of the impact to human synovial；In addition, this practicality Life Of Type is grown, and wear-resisting antiskid, cost is low, and security is good.

Specifically, the shape of buffer groove 122 and damping projection 112 is circular arc, and the depth of buffer groove 122 is small In the height of damping projection 112 so that produce gap between buffer layer 11 and cushion 12, increase plastic cement race track elasticity and Gas permeability.

In order to increase the contact area of supporting layer 13 and ground, so as to increase fixed fastness, it is preferred that in supporting layer 13 lower surface is provided with wave-shaped gap 3, and the depth capacity of breach 3 is 1-5mm, effectively prevents breach 3 is too deep to reduce branch The intensity of layer 13 is supportted, it is too shallow, do not have the effect of increase contact area.

Specifically, skid resistant course 22 is shaped as grid type, and is made using quartz sand, effectively increases plastic cement race track Aesthetics and skid resistance, while sole contact friction force when improving surface strength and the motion of plastic cement race track prevents motion from falling It is injured.

Preferably, multiple through holes 4 through upper and lower surface are additionally provided with buffer layer 11, so as to further increase plastic cement race track Gas permeability, while reduce the weight of buffer layer 11, and save material；Surface of multiple through holes 4 along buffer layer 11 is uniformly distributed, Ensure that buffer layer 11 is hit the uniformity of power, improves service life.

More than, only specific embodiment of the present utility model, but the scope of protection of the utility model is not limited thereto, Any change or replacement expected without creative work, should all cover within the scope of protection of the utility model.Therefore, The scope of protection of the utility model should be determined by the scope of protection defined in the claims.
