Description

一种增强异型材及其制备方法和应用 技术领域
本发明涉及塑料型材技术领域，具体涉及一种增强异型材及其制备方法和应用。
背景技术
衣柜，橱柜，办公桌的主体板材使用三聚氰胺板，密度板或刨花板，但由于不同型号产品的尺寸不一样，在制作过程中都需要按照不同尺寸把主体板材锯开，那么锯开的部分就是裸露的板芯，严重影响产品的外观，所以就需要包边材料把裸露的板芯部分包住，包边的好坏也是衡量衣柜质量的一个重要标准。另外，包边材料还对柜体的变形起着重要的作用，所以衣柜的包边材料还需要一定的强度，刚性等要求。
目前，主要是采用铝合金包边条应用在衣柜，橱柜，办公桌等方面。与钢材相比，铝合金具有材料轻，强度高，密闭性能好，耐腐蚀效果好，安装时变形小等优点，但是铝合金包边材料也存在以下不足之处：铝合金包边材料的生产能耗高，保温隔热、隔音效果差，材料密度大，颜色单一，而且在安装时，工艺复杂。

Figure PCTCN2017087963-appb-000003
由表2可以看出，本发明利用木纹纸作为皮层，其光泽度达到90°以上，较铝合金的光泽度(70°左右)有明显提高，可提供优异的外观效果，高刚性增强苯乙烯基组合物材料作为芯层，其可提供包边材料所需要的强度，刚性等使用性能，此外二者复合制备得到的增强异型材的导热率为0.20-0.30W/mK，显著低于铝合金的热导率(200W/mK左右)，因此，本发明的增强型材具有更低的热导率，在保温隔热，外观效果方面更加具有优势。本发明制备的异型材可代替铝合金包边材料，在办公桌、橱柜、衣柜包边等具有较好的应用前景。
