Description

自增强型塑料异型材及其生产方法
技术领域
本发明涉及专利分类号C08：有机高分子化合物；其制备或化学加工；以其为基料的组合物。
背景技术
门窗在建筑物上要承受来自环境方面的影响，主要是风压力和雨雪侵袭，同时也要承受使用中开关力和自身的重力。其中风力是使门窗的杆件（作为分格型材的横杆、竖梃、窗棂）和框、扇产生弯曲变形的主要原因，门窗是否安全，主要看它承受风力的能力，通常以单位面积上承受的气体压力值来衡量。
硬质PVC塑料，即塑钢型材的力学性能远比钢、铝、木差，尤其是塑钢型材的弯曲强度只有木材的1／4、铝材的1／28、钢材的1／84，塑钢型材异型材在断面形状和尺寸与铝、钢异型材相同的条件下，其弯曲性能差很多。为了弥补这个缺点，一个重要措施就是在门窗的单根型材超过一定长度时，在塑钢型材的空腔内加装钢制的增强型钢即钢衬。
加装钢衬虽然能够解决塑钢型材的强度不足的问题，但是也带了一些负面缺点。
通常的，钢衬和塑钢型材都是分开存放的，在门窗安装时，需要安装人员在施工现场将钢衬和塑钢型材固定，增加了门窗安装的装配工序，要求现场安装人员具有相当的技术与熟练度；钢材的大量使用不可避免的造成了严重的浪费；而且钢材的存储和运输也有一定的要求，比如要注意防水、要保持刚才的清洁以及要远离有腐蚀作用的物品等；更主要的，由于钢衬是金属，是热的良导体，增加了塑钢门窗的传热系数，降低了塑钢门窗的保温系能，不利于保温节能。
