PU composite thermal insulation material
The invention relates to the technical field of building thermal insulation materials, in particular to a PU composite thermal insulation material which is prepared from the following raw materials in parts by weight: 30-60 parts of perlite, 10-30 parts of polyurethane, 5-15 parts of a water-based expandable resin copolymer, 90-150 parts of water, 1-2 parts of a water reducing agent, 1-2 parts of a water increasing agent, 1-2 parts of a foaming agent, 1-2 parts of a foam stabilizer and 1-2 parts of an accelerator. The thermal insulation material has good thermal stability, and the fireproof performance of the thermal insulation material can be improved by using the perlite as the thermal insulation coarse aggregate and the main component.
本发明涉及建筑保温材料技术领域，具体为一种PU复合保温材料，所述PU复合保温材料由以下重量份数的原料组成:珍珠岩30‑60份、聚氨酯10‑30份、水性可发性树脂系共聚物5‑15份、水90‑150份、减水剂1‑2份、增水剂1‑2份、发泡剂1‑2份、稳泡剂1‑2份、速凝剂1‑2份，该发明具有良好的热稳定性，用珍珠岩作为保温粗骨料和主要成分可以提升保温材料的防火性能。
