| 环氧树脂是指分子中含有两个以上环氧基团的一类聚合物的总称。它是环氧氯丙烷与双酚A或多元醇的缩聚产物。由于环氧基的化学活性，可用多种含有活泼氢的化合物使其开环，固化交联生成网状结构，因此它是一种热固性树脂。双酚A 型环氧树脂不仅产量最大，品种最全，而且新的改性品种仍在不断增加，质量正在不断提高。 Epoxy resin is a kind of polymer with more than two epoxy groups in the molecule. It is a condensation product of epichlorohydrin with bisphenol A or polyol. Because of the chemical activity of epoxy group, a variety of compounds containing active hydrogen can be used to open the ring, curing and crosslinking to shuiniguan.37ix.com.cntaoci.37ix.com.cnchongdian.89ix.comkongzhifa.89ix.compeidiand.89ix.com shiyand.89ix.comform a network structure, so it is a thermosetting resin. Bisphenol A epoxy resin not only has the largest yield and the most complete variety, but also the new modified varieties are still increasing and the quality is constantly improving. |
