聚氨酯塑膠跑道材料屬于澆(jiao)注型(xing)聚(ju)氨酯彈(dan)性體(ti)的一種(zhong)，由于其具有高(gao)(gao)彈(dan)性和高(gao)(gao)耐(nai)磨性，越來越多地(di)應用(yong)于鋪(pu)(pu)設各種(zhong)體(ti)育運動場(chang)地(di)，是目(mu)前國際上公認(ren)的運動場(chang)地(di)的鋪(pu)(pu)裝(zhuang)材料(liao)之一。

塑(su)膠跑(pao)(pao)道(dao)與(yu)煤渣、沙石場地相(xiang)比(bi)，具有彈性(xing)好(hao)，吸震(zhen)性(xing)能好(hao)，耐磨和抗(kang)老化(hua)等優(you)點(dian)，不(bu)污染環(huan)境，易于清潔和維(wei)護管理。自第19屆奧(ao)運會之(zhi)后，歷屆奧(ao)林匹克運動會的田徑賽(sai)場主(zhu)跑(pao)(pao)道(dao)與(yu)輔助區均采(cai)用塑(su)膠鋪(pu)裝，塑(su)膠跑(pao)(pao)道(dao)已被國(guo)際公認為(wei)最佳比(bi)賽(sai)跑(pao)(pao)道(dao)。

塑(su)膠(jiao)(jiao)(jiao)(jiao)(jiao)跑道(dao)從(cong)下到上一般分(fen)為(wei)基礎層(ceng)(ceng)(ceng)和(he)膠(jiao)(jiao)(jiao)(jiao)(jiao)面(mian)(mian)(mian)層(ceng)(ceng)(ceng)，一般膠(jiao)(jiao)(jiao)(jiao)(jiao)面(mian)(mian)(mian)層(ceng)(ceng)(ceng)由(you)彈性高分(fen)子材料構(gou)成(cheng)，膠(jiao)(jiao)(jiao)(jiao)(jiao)面(mian)(mian)(mian)可(ke)(ke)以是(shi)有橡(xiang)膠(jiao)(jiao)(jiao)(jiao)(jiao)顆粒(li)或(huo)無(wu)顆粒(li)的(de)塑(su)膠(jiao)(jiao)(jiao)(jiao)(jiao)跑道(dao)。膠(jiao)(jiao)(jiao)(jiao)(jiao)面(mian)(mian)(mian)層(ceng)(ceng)(ceng)主要由(you)聚氨酯材料組(zu)成(cheng)的(de)稱為(wei)聚氨酯塑(su)膠(jiao)(jiao)(jiao)(jiao)(jiao)跑道(dao)，按原料組(zu)分(fen)可(ke)(ke)分(fen)為(wei)單組(zu)份塑(su)膠(jiao)(jiao)(jiao)(jiao)(jiao)跑道(dao)、雙組(zu)份塑(su)膠(jiao)(jiao)(jiao)(jiao)(jiao)跑道(dao)；按膠(jiao)(jiao)(jiao)(jiao)(jiao)面(mian)(mian)(mian)層(ceng)(ceng)(ceng)構(gou)造可(ke)(ke)分(fen)為(wei)全塑(su)型(xing)(聚氨酯膠(jiao)(jiao)(jiao)(jiao)(jiao)面(mian)(mian)(mian)層(ceng)(ceng)(ceng)全部采用(yong)聚氨酯材料或(huo)橡(xiang)膠(jiao)(jiao)(jiao)(jiao)(jiao)粒(li))、復(fu)合型(xing)(又(you)稱透氣型(xing)，膠(jiao)(jiao)(jiao)(jiao)(jiao)面(mian)(mian)(mian)層(ceng)(ceng)(ceng)為(wei)雙層(ceng)(ceng)(ceng)結構(gou)) 、混合型(xing)(由(you)PU 膠(jiao)(jiao)(jiao)(jiao)(jiao)粒(li)或(huo)橡(xiang)膠(jiao)(jiao)(jiao)(jiao)(jiao)膠(jiao)(jiao)(jiao)(jiao)(jiao)粒(li)混合后(hou)固化(hua)成(cheng)型(xing))。

塑膠跑道(dao)有采用(yong)(yong)澆(jiao)注方(fang)法直接鋪(pu)設(she)常規跑道(dao)，還(huan)有攜帶方(fang)便可用(yong)(yong)于多(duo)種場(chang)(chang)合折疊(die)成卷的(de)橡膠板形式的(de)便攜式跑道(dao)。隨著人們環(huan)保意識的(de)提高(gao)和國內市場(chang)(chang)的(de)需求(qiu)，聚(ju)氨酯塑膠跑道(dao)將向環(huan)保、低毒、無害、低成本、高(gao)性能等方(fang)向發展。
