Description

一种新风盾构管及其制备方法
技术领域
本发明涉及一种用于新风盾构管内外壁的配方设计及其制备方法。
背景技术
随着人们生活水平的提高，人们对室内的空气质量的要求也不断提高，新风系统应运而生。我国目前新风盾构管基本靠国外进口，在国内基本属于空白状况。但市场对新风盾构管的需求在逐年增加，高品质、高质量的产品占据市场的需求越来越大，新配方、新工艺的开发越来越急迫。
传统的新风盾构管弯曲性差、环刚度低，不能适应市场的需求。
发明内容
为了克服传统的新风盾构管弯曲性差、环刚度低的缺点，本发明提出一种新风盾构管，包括外壁和内壁，其特征在于，所述外壁和内壁的材料由如下重量份的组分组成：外壁
嵌段共聚聚丙烯(PPB) 100份
色母 1-2份
内壁
Figure BDA0002337070550000011
优选地，所述嵌段共聚聚丙烯(PPB)的熔指在0.4-0.5g/10min。所述聚烯烃弹性体(POE)为乙烯-辛烯共聚物，熔指在9-10g/10min，密度在0.852-0.880g/cm3。所述高密度聚乙烯的熔指在0.3-0.5g/10min，密度在0.941-0.960g/cm3。所述加工助剂为聚环氧乙烷，为1,1,2,3,3,3-六氟-1-丙烯与1,1-二氟乙烯的聚合物。
本发明还提出了上述新风盾构管的制备方法，其特征在于，包括如下步骤:
(1)将各个组分在150-170℃的密炼机中共混塑化成团；
(2)将塑化后的料团转移至长径比为32-40的双螺杆共混造粒机中，170-190℃下挤出拉条切粒，70℃热风干燥，即得到半成品；
(3)半成品经过单螺杆共挤机挤出冷却成型，内外壁温度分别为200℃、220℃即可得到成品。
本发明的新风盾构管具有以下特点：1.采用嵌段共聚聚丙烯(PPB)作外壁料，管材的环刚度提高了200％，弯曲性能有了很大的提高；2.内壁采用了聚烯烃弹性体(POE)，增加了管材的韧性，提高了施工性能；3.内壁增加了加工助剂，改善了材料的黏模性，大大降低了能耗，提升了加工性能。
通过改进现有新风盾构管的材料配方，本发明的新型新风盾构管具有高环刚度、弯曲性好、粘结性强等特点，普适于家装、工程新风系统安装。
