Composition board with heat preservation function and preparation method thereof
The invention relates to a composition board with a heat preservation function and a preparation method thereof, and belongs to the technical field of energy-saving material boards. The composite board comprises a supporting body and a cavity in the supporting body, the cavity is filled with a modified polyurethane foaming material, and the supporting body is made of a cement-based organic and inorganic thermal insulation material. On one hand, the thermal insulation accelerant is introduced into the cement-based material, so that the material has excellent flame retardance, and the modified polypropylene fibers are introduced, so that the material has excellent compressive strength; on the other hand, the flame-retardant auxiliary agent is introduced into the modified polyurethane foaming material, the defect that the polyurethane foaming material is inflammable is overcome, and foaming polyurethane contains a large number of bubbles and has the excellent heat preservation characteristic, so that the modified polyurethane foaming material has the excellent heat preservation performance and the flame-retardant characteristic. Therefore, the composition board provided by the invention has excellent thermal insulation performance and has the advantages of low combustion and small smoke amount during combustion.
本发明涉及一种具有保温功能的组合板及其制备方法，属于节能材料板技术领域。所述组合板包括支撑体和支撑体内的空腔，空腔内填充有改性聚氨酯发泡材料，所述支撑体为水泥基有机无机保温材料。本发明一方面通过在水泥基材料中引入保温促进剂使得该材料具有优异的阻燃性能，引入改性聚丙烯纤维，使得该材料具有优异的抗压强度；另一方面在改性聚氨酯发泡材料内引入阻燃助剂，改善聚氨酯发泡材料易燃的缺点，且发泡聚氨酯因其材料内含有大量的气泡，自身具有优异的保温特性，使得改性聚氨酯发泡材料既具有优异的保温性能，又具有阻燃特性。因此，本发明提供的组合板具有优异的保温性能，且具有低燃、燃烧时烟量少的优点。
