Xt - p1007 unsaturated polyester resin is reactive flame retardant resin , pultrusion process for the production of specialized fire retardant products P1007不飽和聚酯樹脂是反應(yīng)型阻燃樹脂,專門用于生產(chǎn)拉擠工藝阻燃產(chǎn)品。
Xt - p1007 unsaturated polyester resin is reactive flame retardant resin , heat distortion temperature , curing speed , good soak and toughness , both major requirements for flame - retardant and high mechanical strength requirements pultruded products P1007不飽和聚酯樹脂是反應(yīng)型阻燃樹脂,熱變形溫度高,固化速度快,優(yōu)良的浸透性和韌性,主要應(yīng)用于既要求阻燃又要求機(jī)械強(qiáng)度高的拉擠產(chǎn)品。
However , most of those flame retardants will reduce the other properties of materials at the same time . to overcome this drawback , a reactive flame retardant , which was incorporated in the main chain of pet , was used and an intercalative polymerization to layered silicates was conducted so as to prepare novel flame - retardant copolyesters / layered silicate nanocomposites 為了克服這一缺點(diǎn),我們?cè)谝胍环N反應(yīng)型含磷阻燃劑的同時(shí),通過(guò)插層聚合的方法合成了一種新型的聚合物材料:主鏈含磷阻燃共聚酯層狀硅酸鹽納米復(fù)合材料,以期在提高聚合物阻燃性的同時(shí),亦改善材料的其它性能。
The flame retardancy and the comprehensive performance of polyesters were improved . the reactive flame retardant used is 2 - carboxyethl ( phoyl ) phosphinic acid ( cepp ) , and the layered silicate selected is organic montmorillnite ( o - mmt ) . when the contents of cepp and o - mmt are 3wt % , respectively , loi value of the copolyester / montmorillnite composite reaches 32 % 當(dāng)阻燃劑和蒙脫土的含量均達(dá)到3時(shí),復(fù)合材料的限氧指數(shù)可達(dá)32以上,阻燃劑和蒙脫土表現(xiàn)出良好的協(xié)同阻燃作用,同時(shí)復(fù)合材料在熱穩(wěn)定性能以及結(jié)晶性能等方面也有所改善。
