Solid waste-based composite thermal insulation material as well as preparation method and application thereof
The invention belongs to the technical field of thermal insulation materials, and provides a solid-waste-based composite thermal insulation material and a preparation method and application thereof. The cement and other raw materials are mutually combined to form a firm structure; by adding the coal gangue powder, the toughness and durability of the material are improved, the production cost is reduced, and industrial solid wastes are effectively utilized; desulfurization gypsum is added to achieve the purpose of hardening; the added waste rubber powder can improve the flexibility and flame retardance of the polyphenyl granule thermal insulation material; the added shell can increase the porosity of the material and improve the thermal insulation performance; the added polyphenyl particles can improve the thermal insulation performance and reduce the weight of the material. In addition, the apparent density of the solid waste-based composite thermal insulation material provided by the invention is 163 kg/m < 3 >, the compressive strength is 1.1 MPa, the heat conductivity coefficient (normal temperature) is 0.046 W/(m.k), the dry density is 45 kg/m < 3 >, and the combustion performance is A grade.
本发明属于保温材料技术领域，提供一种固废基复合保温材料及其制备方法和应用。本发明利用水泥与其他原材料相互结合形成坚固的结构；通过添加煤矸石粉提高材料的韧性和耐久性，降低生产成本，且有效利用了工业固废；添加脱硫石膏达到硬化的目的；添加废弃橡胶粉可提高聚苯颗粒保温材料的柔韧性和阻燃性；添加贝壳可以增加材料孔隙率，提高保温性能；添加聚苯颗粒可以提高保温性能，减轻材料重量。并且，本发明提供的固废基复合保温材料表观密度为163kg/m3，抗压强度为1.1MPa，导热系数(常温)为0.046W/(m·k)，干密度为45kg/m3，燃烧性能为A级。
