Description
Technical field
The present invention relates to a kind of complex plastic runways, and in particular to a kind of nontoxic complex plastic runway of flame-proof abrasion-resistant and its
Preparation method.
Background technique
The research and use of plastic cement race track start from the sixties in last century, and that develop technique at first is U.S. 3M
Company.The said firm in 1961 has tentatively been laid with one 200 meters long of horse racing road with urethane rubber materials.Then exist
1963,3M company was just laid with first track and field runway in the world with polyurethane material.Since plastic cement race track is unusual
Using effect gradually causes the concern of countries in the world sporting world.Then in year 1965, formally to start production poly- for preceding Germany
Urethane plastic cement race track.It the use of plastic cement race track is first 1967 in the Pan American held of Canada in international sport contest
Move meeting.A booming period is entered from this polyurethane plastic runway.
Hebei Great Wall rubber company is the producer that China produces plastic cement race track earliest.In the seventies latter stage in last century, length
City rubber company starts to produce plastic cement race track.Elasticity is good for polyurethane plastic runway, wear-resisting, anti-skidding, and the place being laid to it is flat
It is smooth uniformly to can absorb vibration, it bounces freely, it is exactly in peacetime training that sportsman, which not only can be improved sports achievement in match,
When can also mitigate sports fatigue to a certain extent, help to improve training effect, along with the distinctive cushion performance of plastic cement also
Sportsman can be played a certain protective role.So plastic cement race track is also gradually developed in China.Especially into new
Since century, Chinese national economy sustained and rapid development, sports industry, which continues to develop, grows, and nationwide fitness programs are like a raging fire,
The development of plastic cement race track enters a completely new developing period.
But in the use process of plastic cement race track, there are some problems: (1) track material is poisonous and harmful, influences green few
Year is healthy；(2) anti-flammability is not high, easily generation fire, seriously affects safety；(3) abrasion resistant effect is bad, and the service life is short, influences economy
