Description

一种防火复合保温板及其制备方法和应用A kind of fireproof composite thermal insulation board and its preparation method and application 技术领域technical field
本发明属于墙体保温材料领域，具体涉及一种防火复合保温板及其制备方法和应用。The invention belongs to the field of wall thermal insulation materials, and particularly relates to a fireproof composite thermal insulation board and a preparation method and application thereof.
背景技术Background technique
节能减排是我国的基本国策，建筑能耗占我国能耗的三分之一左右。在我国北方地区，政府推行75节能要求。目前，建筑墙体保温一般是在墙体上进行保温处理，而市面上常见的传统保温材料主要分为无机保温材料和有机保温材料。无机保温材料防火性能好，但其保温效果不理想；有机保温材料保温性能相对较好、自重轻、强度高、吸水率低，但其易燃、防火性能差。但在满足75节能要求的情况下，保温材料的厚度这就限制了这些保温材料在建筑领域的应用。Energy conservation and emission reduction is my country's basic national policy, and building energy consumption accounts for about one-third of my country's energy consumption. In northern China, the government implements 75 energy-saving requirements. At present, building wall insulation is generally carried out on the wall, while traditional thermal insulation materials commonly found on the market are mainly divided into inorganic thermal insulation materials and organic thermal insulation materials. Inorganic thermal insulation materials have good fire performance, but their thermal insulation effect is not ideal; organic thermal insulation materials have relatively good thermal insulation performance, light weight, high strength, and low water absorption, but their flammability and fire performance are poor. However, in the case of meeting the energy-saving requirements of 75, the thickness of the thermal insulation material limits the application of these thermal insulation materials in the construction field.
目前，用于建筑墙体外墙保温的主要是有机保温材料，如：聚苯乙烯泡沫板、挤塑聚苯乙烯泡沫板、硬泡聚氨酯、酚醛板等，但是这类有机保温材料防火性能差。At present, organic thermal insulation materials are mainly used for thermal insulation of building walls and external walls, such as: polystyrene foam board, extruded polystyrene foam board, rigid polyurethane foam, phenolic board, etc., but such organic thermal insulation materials have poor fire resistance .
真空绝热板作为一种新型保温隔热材料，具有优良的保温性能，导热系数可低至0.0020W/(m·k)以下，在达到同等保温效果的情况下，真空绝热板的使用厚度仅为其他传统材料的十分之一。因此，在建筑节能要求越来越高的情况下，尤其是近年来超低能耗建筑的兴起，对保温材料的保温效果提出了更高的要求，因此高效能的保温材料的使用将是必然趋势，相对于传统的建筑用保温材料，真空绝热板的使用将显著减小墙体保温层的保温厚度，不仅可以增加建筑的使用面积，而且在防火安全方面也具有极大优势，因此该材料在建筑领域的应用越来越普遍。As a new type of thermal insulation material, the vacuum insulation panel has excellent thermal insulation performance, and the thermal conductivity can be as low as 0.0020W/(m·k) or less. Under the condition of achieving the same thermal insulation effect, the thickness of the vacuum insulation panel is only One-tenth of other traditional materials. Therefore, in the case of higher and higher requirements for building energy conservation, especially the rise of ultra-low energy consumption buildings in recent years, higher requirements have been placed on the thermal insulation effect of thermal insulation materials. Therefore, the use of high-efficiency thermal insulation materials will be an inevitable trend. , Compared with traditional building insulation materials, the use of vacuum insulation panels will significantly reduce the insulation thickness of the wall insulation layer, which can not only increase the usable area of the building, but also have great advantages in fire safety. Applications in the field of construction are becoming more and more common.

However, this method has cement polystyrene particle mortar. The defect of low bonding strength with the STP board results in the polystyrene particles falling off easily and the strength is not high. The above problems are technical problems that need to be solved urgently in the art.
