Abstract

The utility model is composed of two plastic layers, wherein a lower layer is lower-layer plastic which comprises black rubber particulates, an upper layer is surface glue, and a surface layer has a mould pressing mold. The utility model overcomes the defect that the antiskid performance of a particulate plastic track is reduced because of the shedding of the plastic particulates; the embossing of the surface is designed beautifully and durably.

Description

Plastic cement race track

The utility model relates to plasthetics, particularly plastic cement race track.

Existing plastic cement race track is to select for use PPG and isocyanates to make raw material, earlier this two component raw material is stirred at normal temperatures, and mix the black rubber particle, this glue is applied on runway road base then, wipe off, the micelle that will prepare in advance before curing is spread on the surface, makes the glue face solidify the back and is stained with some irregular glue particles at superficial layer.This plastic cement race track combines firmly with the road base, and the glue particle has anti-skidding effect.

The disadvantage of this plastic cement race track is that the glue particle of surface layer is easy to come off, the runway non-skid property behind the glue particle detachment reduces, and influences sports achievement.

The purpose of this utility model is to improve existing plastic cement race track, changes the glue particle of superficial layer into embossing, overcomes the shortcoming that micelle comes off, and has anti-skidding used equally.

The utility model has two-layer plastic layer to constitute, and bottom is the bottom glue that is mixed with the black rubber particle, and surface layer is not for being mixed with the surface layer glue of black rubber particle, and the upper surface of surface layer glue has embossing.Its preparation method adopts the field fabrication method more, on the road base, evenly apply earlier bottom glue, after the bottom adhesive curing, evenly apply surface layer glue again, before the surface layer adhesive curing, carry out pressing mold, pressing mold is that the mould that will make in advance is put in the surface, with stamper tool mould is pressed in the glue-line then, treats after superficial layer solidifies mould to be removed, promptly become the plastic cement race track that the surface has various moulding after the pruning.

The utility model has overcome the granule plastic rubber runway to be reduced because of the non-skid property that the glue particle detachment is caused, and the embossing design on surface was both attractive in appearance, durable again.

Be further described with accompanying drawing below:

Fig. 2 is a partial section of the present utility model;

Fig. 3 gives an example for molding surface;

Fig. 1 is the partial section of the present utility model that does not have bottom glue.

As shown in Figure 2, bottom 1 is for being mixed with the bottom glue of black rubber particle 3, and surface layer 2 is not for being mixed with the surface layer glue of black rubber particle, and the upper surface of surface layer 2 has embossing.This example adopts the field fabrication method, earlier on the runway base, evenly apply the bottom glue that is mixed with black rubber particle 3 in advance and make bottom 1, after bottom 1 solidifies, evenly apply surface glue again and make surface layer 2, before solidifying, surface layer 2 carries out pressing mold, pressing mold is that the mould that will make in advance is put on the surface of surface layer 2, with stamper tool mould is pressed in the glue-line then, treats after surface layer 2 solidifies mould to be removed, become the plastic cement race track that the surface has the mold pressing moulding after the pruning.

As shown in Figure 1, for more smooth runway, also can be without bottom glue, make surface layer 2 and directly on the road base, evenly apply surface layer glue, before surface layer 2 solidifies, carry out pressing mold, treat after surface layer 2 solidifies mould to be removed, become the plastic cement race track that the surface has the mold pressing moulding after the pruning.

Claims

1, plastic cement race track lays plastic layer on the road base, it is characterized in that: the upper surface of plastic layer has the mold pressing moulding.

2, plastic cement race track according to claim 1, it is characterized in that: the plastic layer that is laid has two-layer combining, and lower floor is the bottom glue that contains the black rubber particle, and the upper strata is a surface glue.
