Description
技术领域
本发明属于塑钢型材领域，尤其涉及一种抗冲击门窗塑钢型材及其制备方法。
背景技术
塑钢型材简称塑钢，主要化学成分是PVC，因此也叫PVC型材。是被广泛应用的一种新型的建筑材料，由于其物理性能如刚性、弹性、耐腐蚀，抗老化性能优异，通常用作是铜、锌、铝等有色金属的佳代用品。
在房屋建筑中主要用于推拉，平开门窗、护栏、管材和吊顶材料的应用，通过新的工艺流程处理也广泛用在汽车发动机保护板方面，不仅重量轻，而且韧性好，具有刚的优良性质，有时候也被称作合金塑钢。
虽然塑钢材料广泛应用，但是随着社会的进步，要不断提高其性能，例如强度、韧性、耐热性、保温性、隔音性、抗静电性、耐紫外性等性能。
而且我国塑钢型材绝大部分劣质型材使用铅盐稳定剂，成品含铅量在0.6%－1.2%之间。铅是一种对人体有害的物质，当劣质型材老化时，会析出含铅粉尘，长期接触后会使血液中铅含量超标，甚至铅中毒。因此需要提高塑钢型材的安全性，同时不提高成本。
