Abstract

The utility model discloses a compact self-grained plastic runway, which comprises a bottom coating layer, a compact substrate and a self-grained surface layer. The compact substrate is arranged on the bottom coating layer, and the self-grained surface layer is coated on the compact substrate. The surface abrasion resistance of the compact self-grained plastic runway is improved greatly, thereby resolving the problem that particles are fallen off easily in a process of spreading the particles on surface layers.

Description

A kind of compact is from tying the line plastic cement race track

Technical field:

The utility model relates to a kind of polyurethane plastic runway, is specifically related to a kind of compact from tying the line plastic cement race track.

Background technology:

Along with greatly developing of China's physical culture, educational undertaking, the sports buildings facility has all carried out transforming energetically, especially the sports buildings of school, cinder track, cement track are replaced by macromolecular material, and the runway that polyurethane material is laid progressively becomes the main body of runway.

Existing compact polyurethane plastic runway (being commonly called as traditional) outward appearance is a nutty structure on the market, bottom adopts the bi-component polyurethane ester material to add a certain proportion of rubber grain and lays, before primer is still uncured, at its surperficial spreading one deck ethylene propylene diene rubber particle, its bonding is formed.Adopt the PU runway of this technological forming to have good physical property, the tensile strength height, good elongation rate is arranged, but the ethylene propylene diene rubber particle of surface bonding is easy to come off, particle detachment influences the friction factor of runway, the parameters such as rebound performance of runway, and particle detachment is difficult to maintenance, applying unit can only regularly reclaim cleaning, some producer sprays the fastness that one deck PU slurry increases particle on the ethylene propylene diene rubber particle, but can not fundamentally solve the problem of particle detachment.

The utility model content:

The problem that the utility model comes off easily at present compact polyurethane plastic runway surface particle, and provide a kind of compact from tying the line plastic cement race track, this runway adopts a kind of brand-new structure, can solve the problem that the runway surface particle comes off.

In order to achieve the above object, the utility model adopts following technical scheme:

A kind of compact is from tying the line plastic cement race track, this runway comprises scratch coat, compact basic unit and ties grain surface layer certainly, described compact basic unit is arranged on the described scratch coat, describedly is sprayed in the described compact basic unit from tying grain surface layer, and forms the line of knot certainly of projection in described compact basic unit.

The utility model utilization that obtains according to technique scheme replaces conventional rubber grain from tying line, make the antiskid value on runway surface finish the requirement of International Track Association's " outdoor synthetic materials surface layer track and field track performance specification " that can reach 47 (BPN 20), and the abrasion resistance on runway surface promotes greatly, thoroughly solved the not enough problem of the particle detachment of surface layer spreading particle technology.

Description of drawings:

Further specify the utility model below in conjunction with the drawings and specific embodiments.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is a sectional view of the present utility model.

The specific embodiment:

For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.

Referring to Fig. 1 and Fig. 2, the compact that the utility model provides is from tying line plastic cement race track 100, mainly by scratch coat 101, compact basic unit 102 and tie grain surface layer 103 certainly and form.

Wherein compact basic unit 102 is a compact polyurethane, and it is arranged on the scratch coat 101, is sprayed in the compact basic unit 102 and tie grain surface layer 103 certainly, and forms the line of knot certainly 104 of projection in compact basic unit 102.

According to above-mentioned principle, the utility model is specifically implemented as follows:

At first compact polyurethane is laid on the scratch coat 101, forms runway compact basic unit 102; Finish at base layer construction, finish every other day after the curing,, form a kind of grain surface layer of knot certainly 103 that projection is tied line 104 certainly that has naturally at substrate surface spraying one deck high-strength polyurethane special material.Projection from knot grain surface layer 103 can be by regulating the size of spray gun caliber size, gas output from the height size of tying line 104 parts, and the constructor operates and controls, and surface layer need spray twice, looks the thickness of runway reality, as also not reaching the thickness of regulation, can add the spray number of times.

Runway by above-mentioned construction technology formation, its surperficial antiskid value is finished the requirement of International Track Association's " outdoor synthetic materials surface layer track and field track performance specification " that can reach 47 (BPN 20), and the abrasion resistance on runway surface promotes greatly, thoroughly solved the not enough problem of the particle detachment of surface layer spreading particle technology.

More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the manual just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.

Claims

1. a compact is from tying the line plastic cement race track, it is characterized in that, described runway comprises scratch coat, compact basic unit and ties grain surface layer certainly, described compact basic unit is arranged on the described scratch coat, describedly be sprayed in the described compact basic unit, and in described compact basic unit, form the line of knot certainly of projection from tying grain surface layer.
