Description
技术领域
本发明涉及一种泡沫成型用加工助剂，一种使用所述加工助剂的泡沫成型方法，一种包含所述加工助剂的基于氯乙烯树脂的泡沫成型组合物，以及一种泡沫成型产品。
背景技术
在建筑业中，聚(氯乙烯)(PVC)常以发泡形式使用。泡沫是用化学发泡剂和高分子量加工助剂通过配制而生成的。在挤出期间，发泡剂分解产生溶解在高压PVC熔体中的气体。当它离开模具并且压力下降时，气体形成气泡，使PVC膨胀至其原始体积的两到三倍。此时，PVC气泡破裂，所以加入高分子量加工助剂以增加熔体粘度并提供缠结以防止PVC熔体松弛以及提供额外的离模胀大和进一步的泡沫膨胀。商业泡沫加工助剂是极高分子量(通常1-20Mg/mol)的具有高达30％其它聚丙烯酸基的聚(甲基丙烯酸甲酯)共聚物。
影响泡沫加工助剂效率的主要有三个变量：分子量、分子结构和玻璃化转变温度(Tg)。一般来说，较高分子量产生较高的泡沫膨胀，因为较高分子量具有较高的熔体粘度并提供更多的缠结，并且较少的支化和交联产生较高的泡沫膨胀，因为聚合物可以更好地混入PVC中。另一方面，似乎存在一个最佳的Tg可以提供高的熔体粘度，但同时在挤出过程中仍能够解开。通常，为了提供这些性质，会使用共计15-20％的丙烯酸乙酯(EA)和/或丙烯酸丁酯(BA)。无论EA还是BA，所得共聚物的分子量均低于任何所述组分形成的均聚物，因为MMA与EA或BA的交叉扩展非常缓慢。BA促进了显著的交联，因为聚合物骨架中的叔氢容易被夺取。因此，所述领域中仍然需要改进的发泡助剂。
发明内容
在第一实施例中，本公开提供一种泡沫成型用加工助剂，其包含通过聚合以下各项而获得的共聚物：30到90重量％甲基丙烯酸甲酯、共计10到70重量％一种或多种选自由甲基丙烯酸丁酯(BMA)、甲基丙烯酸戊酯(PMA)和甲基丙烯酸己酯(HMA)组成的群组的单体、以及0到20重量％其它可共聚单体，所述共聚物具有根据ASTM D2857(在1mg/mL下，在氯仿中，在25℃下)测量的大于8dL/g的减小的粘度。
