External thermal insulation integrated non-dismantling formwork and preparation method thereof
The invention relates to the technical field of building materials, and provides an external thermal insulation integrated non-dismantling formwork and a preparation method thereof.The external thermal insulation integrated non-dismantling formwork comprises a hard foam polyurethane layer and an ultra-high performance concrete layer poured on the surface of the hard foam polyurethane layer; comprising the following components in parts by weight: 500-800 parts of cement, 95-152 parts of lightweight aggregate, 450-720 parts of fine sand, 30-55 parts of composite fibers, 1-3 parts of a titanate coupling agent, 100-400 parts of water and 10-15 parts of paraffin, the composite fiber is a mixture of polyformaldehyde fiber and polylactic acid fiber; the hard foam polyurethane layer is prepared from the following components in parts by weight: 90 to 100 parts of polyether polyol, 120 to 130 parts of isocyanate, 1 to 3 parts of a foaming agent, 2 to 4 parts of a foam homogenizing agent and 0.5 to 3 parts of a catalyst. By means of the technical scheme, the problems that in the prior art, the toughness of a non-dismantling heat preservation formwork and the strength of a heat preservation layer are poor are solved.
本发明涉及建筑材料技术领域，提出了一种外保温一体化免拆模板及其制备方法，包括硬泡聚氨酯层和浇筑于硬泡聚氨酯层表面的超高性能混凝土层，超高性能混凝土层的材料，包括以下重量份的组分：水泥500~800份、轻骨料95~152份、细砂450~720份、复合纤维30~55份、钛酸酯偶联剂1~3份、水100~400份、石蜡10~15份；复合纤维为聚甲醛纤维和聚乳酸纤维的混合物；硬泡聚氨酯层的材料，包括以下重量份的组分：聚醚多元醇90~100份、异氰酸酯120~130份、发泡剂1~3份、均泡剂2~4份、催化剂0.5~3份。通过上述技术方案，解决了现有技术中的免拆保温模板的韧性和保温层的强度较差的问题。
