Description
技术领域:
本发明涉及一种铝箔编织布阻燃材料。
背景技术:
传统铝箔编织布复合材料主要用于建筑隔热材料和机械包装等,在传统淋膜复合的过程中,由于330℃的高温淋膜,对HDPE编织布的性能造成了一定的影响,使复合后的材料发脆,发硬,抗撕裂和抗穿刺效果降低明显,其阻燃效果达不到澳洲,美国和欧盟要求,使得应用范围和经济效益受限。
发明内容:
本发明所要解决的技术问题是,提供一种在不影响材料复合牢度和物理性能的前提下,提升整体材料的阻燃性能的铝箔编织布阻燃材料,该铝箔编织布阻燃材料满足国内外建筑隔热保温和特种包装材料的阻燃,保温,反射,隔热要求,应用范围广,经济效益高。
本发明的技术解决方案是,提供一种铝箔编织布阻燃材料,包括由上到下依次设置的铝箔层、阻燃胶层、阻燃编织布层、阻燃胶层和铝箔层,所述铝箔层采用99%铝含量的高纯度铝箔,阻燃胶层采用添加有碳酸钙的聚氨基甲酸酯复合胶水,阻燃编织布层采用低压高密度聚乙烯,阻燃编织布层的上、下表面通过聚氨基甲酸酯复合胶水与铝箔层复合。
采用以上结构后与现有技术相比,本发明具有以下优点:99%铝含量的高纯度铝箔为材料提供了高达97%的反射率和低于3%的发射率。同时铝箔材料的使用为成品材料提供了一定的可塑型性,而且铝箔本身完全阻燃,提升了成品材料的阻燃效果,本材料使用添加有碳酸钙的聚氨基甲酸酯复合胶水作为粘接复合,相较于淋膜和其它胶水复合牢度更好;同时因为添加了阻燃剂,阻燃效果极好,达到不燃的效果,阻燃编织布能够为材料提供良好的阻燃效果,提升抗张和撕裂强度。
作为优选,所述阻燃编织布层为含5-30%阻燃剂的编织布。
本发明还提供一种铝箔编织布阻燃材料的制备方法,包括以下步骤,
第一步,选用7微米厚的99%铝含量的高纯度铝箔,克重60g/m2、阻燃剂比例占10%的低压高密度聚乙烯编织布,低压高密度聚乙烯编织布的颜色根据需要选择;
第二步,调配复合胶水,胶水中各组分的质量百分比如下,聚氨基甲酸酯10-40%,对羟基苯磺酸10-20%,醋酸乙酯10-50%,碳酸钙10-50%,将上述组分混合后搅拌均匀形成复合胶水;
第三步,在5-30℃的干燥无尘环境中,在低压高密度聚乙烯编织布的下表面涂布复合胶水,涂布量控制在1.5-5g/m2,然后与铝箔贴合,然后在低压高密度聚乙烯编织布的上表面涂布复合胶水,涂布量控制在1.5-5g/m2,然后与铝箔贴合;
第四步,将贴合好的铝箔编织布阻燃材料送至干燥区,并依次经过干燥区的四区干燥,四个分区的温度依次为25-65℃、30-70℃、35-75℃、40-80℃,每个分区都有送风装置送风,使得铝箔编织布阻燃材料复合温度最终控制在60-70℃;
第五步,在40-60℃温度下固化48-72h。
该方法使用干式复合方法制得铝箔编织布阻燃材料,能够有效控制温度对基材物理性能的影响,在不影响材料复合牢度和物理性能的前提下,提升整体材料的阻燃性能,采用干复工艺制备阻燃铝箔编织布也大大降低了材料本身的克重,在不影响复合牢度的前提下,使用2-3g的胶水即可替代原本18-20g的淋膜克重,使成品材料更轻便也更易于终端的使用。本发明已经过试制阶段,将投入量产。产品将满足国内外建筑隔热保温和特种包装材料的阻燃,保温,反射,隔热要求,应用范围广泛,社会经济效益显著。
