Description

一种新型遮光XPS挤塑保温板及其制备方法
技术领域
本发明涉及保温板技术领域，具体为一种新型遮光XPS挤塑保温板及其制备方法。
背景技术
XPS挤塑保温板是以聚苯乙烯为主要原料，添加各种加工助剂以及发泡剂，经过挤出成型制得。目前市场上XPS挤塑板大部分应用于民用建筑外墙外保温、屋面保温等领域，XPS挤塑保温板以其封闭的泡孔结构使其具有较好的绝热性、较高的抗压性、较长的使用期和较轻的质量在外墙保温使用已经十几年了，但是传统的XPS挤塑保温板为无色结构，无法遮蔽光照，对一些要求避免光照的地方，使用受到限制。
发明内容
本发明所解决的技术问题在于提供一种新型遮光XPS挤塑保温板及其制备方法，以解决上述背景技术中的问题。
本发明所解决的技术问题采用以下技术方案来实现一种新型遮光XPS挤塑保温板，其成分包括：ps颗粒、阻燃颗粒、阻燃剂、成核剂、蓝色母粒；具体配方由以下重量的原料制成：ps颗粒200kg、阻燃颗粒100kg、阻燃剂24kg、成核剂10kg、蓝色母粒5kg。
进一步的，所述阻燃颗粒为无机阻燃颗粒，具体的为氢氧化铝、氢氧化镁中的任意一个，或是两个。
进一步的，所述成核剂为滑石粉、碳酸钙、二氧化硅、明矾、二氧化钛、氧化钙、氧化镁、炭黑、云母等中的一个或多个。
一种新型遮光XPS挤塑保温板制备方法，具体包括以下步骤：
步骤1：按照：ps颗粒200kg、阻燃颗粒100kg、阻燃剂24kg、成核剂10kg、蓝色母粒5kg的重量成分投入到料斗内充分混合；
步骤2：将混合后的材料由喂料器工机组供料，由工机组内加热、输送、塑化、混炼、注入co2(二氧化碳)；
步骤3：当原料成粘流态时在螺杆的推动下经过换网器连接器输送至工机组，经过二次发泡；
步骤4：由于在机组内注入了co2二氧化碳同时配合发泡剂和成核剂，通过工机组螺杆的搅拌形成了大量的气泡核，在被挤出机挤出模具口的一瞬间，受到大气压的影响，形成一个个独立的气泡，此时的材料周围胀起，将胀起的材料经过平整机压平、整形最后被牵引机牵出；
步骤5：最后经过规格调试出需要的产品，再经过切边、拉毛、开槽、切割和包装最后做出成品。
进一步的，所述的步骤3中二次发泡温度为125℃。
进一步的，所述的步骤4中的挤出机为一阶同向双螺杆与二阶单螺杆挤出机。
进一步的，所述的步骤4中的发泡剂为1,1-二氯乙烷。
与已公开技术相比，本发明存在以下优点：本发明中各物质的合理组合，可是产品具有较好的绝热性、较高的抗压性，同时产品具有遮光的作用，可以使产品满足避光性要求高的场所，扩大了产品使用范围。
