门窗用新型环保异型材的研制

Preparation of Novel Environment-protecting Special-shaped PVC Compound for Door and Window

以木粉 ,PVC树脂等为原料 ,研制了一种门窗新型环保异型材。对该异型材的密度、含水量、吸水性、热变形温度、力学性能等进行了测试。结果表明 :该异型材的密度与原木十分接近 :异型材具有极佳防水性能 ;含水率不超过2 0 % ,吸水性不超过 2 3 8% ;热变形温度为 78 3℃ ,弯曲强度、压缩强度、拉伸强度、拉拔抗强度等力学性能均达到室内装修的基本要求。

s A novel environment protecting architectural materal,LESCO special shaped PVC compound for door and window,was manufactured,using timber powders,poly(vinyl chloride)and et al as raw material,and the properties of the compound were studied in details The density of the compound was nearly close to that of wood,and the content of water was lower than 2 0%,with a water absorbance less than 2 38%,showing excellent water proof property The heat deformation temperature was 78 3℃,higher than that of plastics The mechanical properties such as bending strength,compression strength,tensile shear strength,mechanical fastening(nail),mechanical fastening(screw) and mechanical fastening (staple) all met the need for indoor decoration in the main This special shaped PVC compound could be used in the preparation of door and window instead of wood
