Abstract
The utility model relates to a high elastic light plastic race track which belongs to the technical field of athletic sports articles. The utility model is used for solving the problems of bad shock absorbing performance and bad vertical deformation performance of the plastic race track. The utility model is composed of a surface layer and a base layer which is composed of adhesive and elastic granules. After improvement, the elastic granules are mixed with micropore foaming elastic granules. The utility model is improved by aiming for the defects of the existing plastic race track. The foaming elastic granules are added in the base layer to improve the elasticity of granule bodies. As a result, the elasticity of the whole base layer is improved, and especially the two indexes of the shock absorbing performance and the vertical deformation performance are obviously improved and fully achieve the requirements of relative standards, so the safety and the applicability of the plastic race track are close to be perfect. Furthermore, compared with the prior art, the utility model has the advantages of light weight, low material consumption, etc.
Description
Technical field
The utility model relates to the plastic cement race track of a kind of sporting goods, particularly Track field, belongs to the sports articles for use
Technical field.
Background technology
Plastic cement race track is an indispensable critical facility in the modern track and field place, compare with traditional soil property runway, it has better elastic, skid resistance, abrasion resistance, shock absorption, the place nursing is easy, in bright gay color, attractive in appearance neat, in view of above-mentioned advantage, plastic cement race track comes out and is promptly adopted by each Track field rapidly soon, and is also widely using in some universities, middle school in recent years.Plastic cement race track no matter be site operation or be prefabricated into piece after re-lay, its primary structure all is made up of basic unit and surface layer, the effect of surface layer is wear-resisting, anti-skidding, it is divided into particle type and embossing formula; Basic unit then provides better elastic and shock absorption.At present, basic unit adopts polyurethane binding, a certain proportion of elastic granule of mix mostly, and cast or mold pressing form.The problem that existing plastic cement race track exists is that shock absorbing capability and vertical deformation performance are on the low side, causes the sportsman of some projects to be easy to injured.Be head it off, the insider improves, as improves the performance of adhesive, the ratio that changes elastic granule and material etc., but effect is all not obvious, fails to reach its intended purposes.
Summary of the invention
The utility model is used to solve the defective of above-mentioned prior art and a kind of high-elastic lightweight plastic cement race track with good shock absorbing capability and vertical deformation performance is provided.
The alleged problem of the utility model solves by the following technical programs:
A kind of high-elastic lightweight plastic cement race track comprises surface layer and basic unit in the formation, basic unit is made up of adhesive and elastic granule, and its special feature is to mix the microporous foam elastic granule in the described elastic granule.
Above-mentioned high-elastic lightweight plastic cement race track, 0.1～5 millimeter of described microporous foam elastic granule particle diameter is covered with micropore in it, 1 micron～1 millimeter in aperture, described micropore is through hole or blind hole.
Above-mentioned high-elastic lightweight plastic cement race track, described surface thickness is 3～5 millimeters, described groundwork thickness is 5～30 millimeters.
Above-mentioned high-elastic lightweight plastic cement race track, described microporous foam elastic granule accounts for 10%～50% of elastic granule total amount.
Above-mentioned high-elastic lightweight plastic cement race track, described microporous foam elastic granule adopts rubber pange particle, plastic foamed particle or other elastomeric material expanded beads.
The utility model improves at the drawback of existing plastic cement race track, in basic unit, add the foaming elastic granule, improved the elasticity of filler particles body, thereby the elasticity of whole basic unit is improved, especially these two indexs of shock absorbing capability and vertical deformation performance obviously improve, can reach the requirement of relevant criterion fully, make safety, the applicability of plastic cement race track more become perfect.In addition, compared with prior art, the utility model also has light weight, uses advantages such as material is few.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is a microporous foam elastic granule generalized section (drawing not in scale).
Each label list is shown in the accompanying drawing: 1. surface layer; 2. basic unit; 3. microporous foam elastic granule; 4. entity elastic granule; 5. micropore.
The specific embodiment
Referring to Fig. 1, formation of the present utility model comprises surface layer 1 and basic unit 2, and surface layer can be particle type or embossing formula, and basic unit is made up of adhesive and elastic granule, and adhesive can adopt polyurethanes.Contain microporous foam elastic granule 3 and entity elastic granule 4 in the elastic granule, the two evenly distributes.Referring to Fig. 2, the particle diameter of microporous foam elastic granule is 0.1～5 millimeter, and distribution micropore 5 on it, micropore can be through hole or blind hole, and does not wait for 1 micron～1 millimeter in the aperture.The microporous foam elastic granule is compared with widely used entity elastic granule in the prior art, and density reduces, elasticity increases, so after adding basic unit to, the elasticity of whole basic unit is improved.The addition of microporous foam elastic granule can be optionally with the elasticity of granular material itself and decide, add 10%～50% of particle total amount usually and get final product.
Described microporous foam elastic granule can be rubber pange particle, plastic foamed particle or other elastomeric material expanded beads.Add and according to conventional method rubber, plastic or other material to be made foaming bulk or plates earlier man-hour, form graininess through fragmentation again.Also can directly be processed into expanded beads, as select ground rubber or brand-new rubber powder for use, add an amount of vulcanizing agent, filler, blowing agent, auxiliary agent, fully mixing, add thermal finalization expanded beads.
