Plastic-weather athletics track surface material, the use of polyurethane synthetic rubber, commonly known as PU (Polyurethane), in the nineteenth century by the reaction of an appropriate extension of the scientists of the active hydrogen-containing polyo1 containing isocyanate NCO's and synthesis, founded in the United States in the 1960s once used in the first 1968 Olympic Games in Mexico nineteenth rave reviews, since the plastic runway in the world becoming more common. Its main characteristics are: strong bonding strength and flexibility runway material sales, flexibility and good weather resistance, oil resistance, solvents, acid-alkaline good, simple construction, easy maintenance runway material, because of its superior characteristics, early twentieth century it was recognized by the International Olympic Committee as the surface layer of the dressing athletics track laid its unrivaled position in the sports arena. Currently, the only score of the game on the ground plastic stadium was only recognized by the IOC and IAAF. With the further development of China's economy, improve people's material level, is certainly greatly improve people's enthusiasm to participate in sports; excellent sports venues, will be the first choice, therefore, new or rebuilt plastic track is bound to become a trend. Artificial turf by three layers of materials. Base layer is made of compacted soil, gravel and asphalt or concrete layer. Requires a solid base layer, deformation, surface smooth and impermeable, namely general concrete venue. Due to the large area hockey venue, must handle the construction of the base layer to prevent subsidence. If laying concrete layer, after curing of concrete expansion joints to be cut out, to prevent thermal expansion deformation and fracture. Above the base layer is a buffer layer, usually composed of rubber or foam. Rubber elastic medium, thickness 3 ~ 5mm. Foam with a lower cost, but poor flexibility runway materials manufacturers, the thickness of 5 ~ 10mm, thick lawn is too soft, and easy to depression; lack of elasticity is too thin, would not achieve the buffer. The buffer layer must be firmly attached to the base layer of the runway direct materials, general purpose adhesive with white latex or paste. The emergence of artificial turf stadium can be traced back to the sixties. They are the invention of a military project in the United States, to improve the urban teenager's body. It is called "astro turf", which quickly became an affordable, durable and low maintenance turf maintenance of natural alternatives, and quickly applied to American football, baseball and soccer stadium. With football, tennis, golf and other sports professional, industrial, commercial development makes the development of sport artificial turf industry has made some progress in recent years.
