一种用物理发泡工艺一次性挤出成型生产XPS装饰条异型材檐板的方法
技术领域
本发明涉及装饰材料挤出生产领域,尤其涉及一种用物理发泡工艺一次性挤出成型生产XPS装饰条异型材檐板的方法。 
背景技术
    目前,对于外墙或室内的装修,一般都会通过装饰材料来完成,从而起到保温或给环境营造更美色彩的作用。现有技术中可以采用木材或石膏,采用木材或石膏存在以下缺陷,首先是容易吸水造成变形、开裂等现象;其次木材的过多使用会破坏生态环境,而石膏也属于一次性,不可循环利用;此外石膏柔韧性较差且重量大,不易搬运。鉴于上述木材和石膏存在的问题,就开始选用EPS装饰材料,此种装饰材料是采用聚苯乙烯原料经蒸汽发泡、成型、切割制成的,具有抗水汽渗透、重量轻,可再生循环利用等特点,但是这种装饰材料表面粗糙,生产效率低,尽管具有抗水汽渗透性,但还是会吸水,长时间使用,存在其热阻系数会逐渐增大、抗压及承载力变差,使用寿命短的缺陷。 
发明内容
本发明针对上述现有技术存在的不足,提供了一种物理发泡工艺一次性挤出成型生产XPS装饰条异型材檐板的方法,此方法生产出来的XPS装饰条檐板表面光滑细腻,不易变形、不开裂,是一种新型优质环保的装饰材料。 
  
本发明解决上述技术问题的技术方案如下:
(1)       一种用物理发泡工艺一次性挤出成型生产XPS装饰条异型材檐板的方法,包括以下步骤:将PS树脂或再生颗粒100份,滑石粉1份,适量的着色剂混合搅拌均匀成混合料;
(2)  将上述混合料经上料系统送入挤出系统挤压熔融,温度控制在200℃,同时注入发泡剂,压力在10MPa,
(3)  再经过机头口模发泡,冷却定型;
(4)  牵引喷码,计米切断至成品。
(5)  进一步,所述的挤出系统为一级挤出机和二级挤出机串联,一级挤出机和二级挤出机中间设有换网器,熔融树脂经过换网器过滤杂质,之后送入到第二级挤出机,进一步搅拌,经过动态或静态恒温混合,再冷却降温。 
     进一步的,所述的挤出系统为单螺杆挤出机或双螺杆挤出机,挤出机后设有换网器,熔融树脂经过换网器过滤杂质,进一步搅拌,经过动态或静态恒温混合,再冷却降温。 
     进一步的,所述的发泡剂为二氧化碳、丁烷或氟利昂。 
本发明的有益效果是:本发明采用物理发泡的生产系统一次挤出成型XPS装饰条异型材檐板,是一种新型的内外墙装饰线条及构件,本方法生产速度快,效率高,通过本发明生产的装饰条重量轻,易于搬运,表面光滑,既能体现高雅的装饰风格,还避免出现冷热桥效应,此外其耐候性好,无裂缝,可随意切割、拼接、组合,安装过程方便,外型美观,采用可循环再生料生产是一种环保的优质装饰材料。本产品可以代替传统的水泥、石膏、木材、PVC、EPS等装饰条构件。
