Abstract
The utility model belongs to the technical field of sports goods, in particular to a rubber race track laid on track and field grounds. The utility model adopts the technical scheme that the plastic race-track comprises a bottom layer, a base layer and a surface layer which are sequentially laid and integrally formed, and is characterized in that the bottom layer is formed by laying black crumb rubber; the base layer is arranged on the upper surface of the bottom layer and is formed by laying ethylene-propylene-diene crumb rubber; and the surface layer adopts an ethylene-propylene-diene monomer rubber layer which is spray-coated on the upper surface of the base layer. The rubber race track has the advantages that since the bottom layer adopts black crumb rubber which come from junked tires, the raw material cost is low, the problem of difficult treating of junked tires which are non-degradable by selves is effectively solved, and the construction of the race track adopting the rubber conforms to environmental protection requirements; the black crumb rubber is bouncy and thicker, thereby playing a role of leveling the ground; and the surface layer and an interlayer are thick with strong abrasion resistance property and good nail resistance, thereby meeting the requirements of strength of special track-and-field grounds.
Description
Technical field
The utility model belongs to sports articles for use technical field, specifically is the plastic cement race track that the confession under directions Track field is laid.
Background technology
Plastic cement race track is an indispensable critical facility in the modern track and field place, compares with traditional soil property runway, and it has better elastic, skid resistance, abrasion resistance, shock absorption, and place nursing easily, and is in bright gay color, advantage such as neat attractive in appearance.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.
Existing plastic cement race track is divided into two kinds of mixed type plastic track and vapor-permeable type plastic cement race tracks, and its primary structure all is made up of basic unit and top layer, and the effect on top layer is wear-resisting, anti-skidding; The effect of basic unit provides better elastic and shock absorption.The basic unit of existing mixed type plastic track mixes the back laying by two component polyurethane and the black particle of rubber to form in proportion, and the top layer is mixed the back by bi-component polyurethane ester gum and colored particle and laid; The disadvantage of its existence is airtight.When surface temperature is higher, can't penetrate runway from the steam of underground evaporation, under runway, form bubble, thereby destroyed the adhesion stress on runway and ground.In addition, also there is impermeable shortcoming in mixed type plastic track, the rainy weather in south particularly, the easy ponding of runway.In addition, the particle on this mixed type plastic track surface comes off easily, has only 7-8 application life usually, needs afterwards manually to lay again; Waste time and energy and the processing cost height.
The basic unit of existing vapor-permeable type plastic cement race track is the mixture that is made of black rubber particle and adhesive for polyurethane, and the top layer is the color paste layer that is sprayed in the basic unit.Disclose a kind of athletic ground vapor-permeable type plastic cement race track coiled material [patent No.: ZL 200820071929.3] as Chinese patent literature, this coiled material is made of basic unit and surface layer, and wherein, basic unit mixes the back by black micelle to lay moulding with adhesive for polyurethane; The top layer is the mixture that sprays in basic unit, and this mixture is made up of Ethylene Propylene Terpolymer micelle, Ethylene Propylene Terpolymer powder and color and adhesive for polyurethane.This runway is because its basic unit adopts black micelle, and low, the anti-nail power of its intensity is poor; Can be subjected to the destruction of spikes or block and damage runway.Therefore, exist application life short, do not meet the requirement of professional sports ground; In addition, after this runway damaged, its material can not be recycled.
The utility model content
The purpose of this utility model is to have the problems referred to above at prior art, provides that a kind of cost of production is low, abrasion resistance is strong, good permeability, long service life and the plastic cement race track that can recycle.
The purpose of this utility model realizes by following technical proposal: a kind of plastic cement race track, comprise and lay bottom, basic unit and the top layer that is shaped to one successively, it is characterized in that: described bottom is laid by the black rubber particle and is formed, basic unit is arranged on the bottom upper surface, is to be laid by the ethylene propylene diene rubber particle to form; Described top layer is the Ethylene Propylene Terpolymer glue granular layer that is sprayed on basic unit's upper surface.
This runway bottom that the utility model provides adopts the black rubber particle, because the black rubber particle is taken from junked tire, it is cheap not only to have a cost of material, and has solved junked tire effectively because of the reluctant problem of can not degrading automatically.Basic unit adopts the ethylene propylene diene rubber particle, because the ethylene propylene diene rubber particle has good heat resistanceheat resistant, antioxygenic property, and water absorption rate is low; Have hot strength preferably, higher compact strength by its runway that makes as basic unit, and strong, the anti-nail power of abrasion resistance is good; Can not be subjected to the destruction of spikes or block and damage runway.
At above-mentioned plastic cement race track, the thickness of described bottom is 3～7mm.
At above-mentioned plastic cement race track, the thickness of described bottom is preferably 5mm.
At above-mentioned plastic cement race track, the granularity that constitutes the black rubber particle of bottom is 1～3mm.
At above-mentioned plastic cement race track, the thickness of described basic unit is 6～12mm.
At above-mentioned plastic cement race track, the thickness of described basic unit is preferably 7mm.
At above-mentioned plastic cement race track, the granularity that constitutes the ethylene propylene diene rubber particle of basic unit is 0.5～1.5mm.
At above-mentioned plastic cement race track, the thickness on described top layer is 2～4mm.
At above-mentioned plastic cement race track, the thickness on described top layer is preferably 3mm.
Compared with prior art, the utlity model has following advantage: 1, bottom adopts the black rubber particle, because the black rubber particle is taken from junked tire, it is cheap not only to have cost of material, and solved junked tire effectively because of the reluctant problem of can not degrading automatically, the runway construction compliance with environmental protection requirements of carrying out with it; 2, the black rubber particle is flexible, and thicker, can play the effect of floor leveling; 3, the plastic cement race track cost of manufacture is cheap, intensity is high, ventilative seepage of water is good, elongation per unit length is big, every physical index meets national standard; 4, the thickness in top layer and intermediate layer is not less than 8mm (because the length of at present common on the market spikes nail is 8mm, the thickness in top layer and intermediate layer is greater than 8mm, make spikes can not hammer in the black rubber particle in use), strong, the anti-nail power of abrasion resistance is good, meets the requirement of professional athletics field to intensity; 5, the top layer of this plastic cement race track can be carried out the secondary spraying in substrate surface, thereby prolong the application life of plastic cement race track after long-term use wearing and tearing, promptly uses the life-span more than 15 years; After damaging fully, its raw material are also recyclable, and processing and utilization is of value to environmental protection once more; 6, the utility model also has advantages such as simple in structure, that cost of production is low in addition.
