萍鄉聚氨酯膠水—塑膠跑道材料
聚氨酯塑膠跑道材料屬于澆(jiao)注型(xing)聚氨酯彈性(xing)體的一種(zhong),由于其具有高(gao)彈性(xing)和(he)高(gao)耐磨(mo)性(xing),越來越多地應用于鋪(pu)(pu)設各(ge)種(zhong)體育運(yun)(yun)動場地,是目(mu)前國際上公認的運(yun)(yun)動場地的鋪(pu)(pu)裝(zhuang)材料之(zhi)一。
塑膠(jiao)跑(pao)(pao)道(dao)(dao)與(yu)煤渣、沙(sha)石場地(di)相比,具有彈性(xing)好,吸震性(xing)能好,耐磨(mo)和(he)抗老化(hua)等優點,不污(wu)染(ran)環境,易(yi)于(yu)清(qing)潔和(he)維護(hu)管理。自第19屆奧(ao)運(yun)會之后,歷屆奧(ao)林匹克運(yun)動(dong)會的田徑賽(sai)場主跑(pao)(pao)道(dao)(dao)與(yu)輔助(zhu)區(qu)均采用塑膠(jiao)鋪裝,塑膠(jiao)跑(pao)(pao)道(dao)(dao)已(yi)被國際公認為(wei)最佳比賽(sai)跑(pao)(pao)道(dao)(dao)。
塑(su)(su)膠(jiao)(jiao)(jiao)(jiao)跑道從下到上一(yi)般(ban)分(fen)為(wei)基礎層(ceng)和膠(jiao)(jiao)(jiao)(jiao)面(mian)(mian)(mian)層(ceng),一(yi)般(ban)膠(jiao)(jiao)(jiao)(jiao)面(mian)(mian)(mian)層(ceng)由彈性高分(fen)子材料(liao)(liao)構(gou)成,膠(jiao)(jiao)(jiao)(jiao)面(mian)(mian)(mian)可以是有(you)橡膠(jiao)(jiao)(jiao)(jiao)顆粒或無顆粒的(de)塑(su)(su)膠(jiao)(jiao)(jiao)(jiao)跑道。膠(jiao)(jiao)(jiao)(jiao)面(mian)(mian)(mian)層(ceng)主要由聚(ju)氨酯(zhi)材料(liao)(liao)組(zu)成的(de)稱為(wei)聚(ju)氨酯(zhi)塑(su)(su)膠(jiao)(jiao)(jiao)(jiao)跑道,按原(yuan)料(liao)(liao)組(zu)分(fen)可分(fen)為(wei)單(dan)組(zu)份(fen)塑(su)(su)膠(jiao)(jiao)(jiao)(jiao)跑道、雙組(zu)份(fen)塑(su)(su)膠(jiao)(jiao)(jiao)(jiao)跑道;按膠(jiao)(jiao)(jiao)(jiao)面(mian)(mian)(mian)層(ceng)構(gou)造(zao)可分(fen)為(wei)全塑(su)(su)型(xing)(聚(ju)氨酯(zhi)膠(jiao)(jiao)(jiao)(jiao)面(mian)(mian)(mian)層(ceng)全部(bu)采用聚(ju)氨酯(zhi)材料(liao)(liao)或橡膠(jiao)(jiao)(jiao)(jiao)粒)、復合(he)型(xing)(又稱透氣(qi)型(xing),膠(jiao)(jiao)(jiao)(jiao)面(mian)(mian)(mian)層(ceng)為(wei)雙層(ceng)結構(gou)) 、混(hun)合(he)型(xing)(由PU 膠(jiao)(jiao)(jiao)(jiao)粒或橡膠(jiao)(jiao)(jiao)(jiao)膠(jiao)(jiao)(jiao)(jiao)粒混(hun)合(he)后固化(hua)成型(xing))。
塑(su)膠(jiao)(jiao)跑(pao)(pao)道(dao)(dao)有采用(yong)澆注方(fang)法直接鋪(pu)設(she)常規跑(pao)(pao)道(dao)(dao),還有攜(xie)帶方(fang)便(bian)可用(yong)于多(duo)種場合折(zhe)疊成(cheng)卷的橡膠(jiao)(jiao)板(ban)形式(shi)的便(bian)攜(xie)式(shi)跑(pao)(pao)道(dao)(dao)。隨著人(ren)們環保意識的提(ti)高和(he)國內市場的需求,聚氨酯塑(su)膠(jiao)(jiao)跑(pao)(pao)道(dao)(dao)將向環保、低毒、無害、低成(cheng)本、高性(xing)能等方(fang)向發(fa)展(zhan)。
