Abstract

基于建筑节能PVC门窗交联技术的门窗型材制备方法，它涉及一种门窗型材制备方法。本发明解决了PVC材料的门窗型材会发生降解，导致门窗的各种性能指标达不到使用要求的问题。一：以高能电子射线作为辐射源，向待制备PVC塑料与铝衬进行内外层共挤，在待制备PVC塑料的外表层添加交联剂；二：在辐射源的作用下待制备PVC塑料的外表面层PVC的C‑CL键发生断裂，形成自由基；三：在辐射源的作用下交联剂产生的自由基进行自聚合反应，在步骤二中待制备PVC塑料的外表面层PVC长链中替代掉CL形成有效接枝；四：调整辐射源的强度，实现形成PVC‑交联剂‑PVC的长链，最终交联剂支链形成网状分布。本发明用于制备门窗型材。
