Description
Technical Field
The invention belongs to the technical field of novel building wall materials, relates to a fireproof and refrigerating heat-insulating board for a building, and particularly relates to a mineral core fireproof and refrigerating organic heat-insulating composite board.
Background
The enclosure system of the building is an important component of the building, the outer wall system of the building is the most important subsystem in the enclosure system of the building, the fire prevention, the heat preservation and the heat insulation of the outer wall of the building are main indexes of the physical performance of the enclosure system of the building, and the quality of the used materials of the enclosure system of the outer wall directly influences the indexes of the performance of the building.
In areas hot in summer and warm in winter, 90% of various heat radiation which is directly emitted and scattered outdoors can enter indoors through walls, window glass, roofs and the like. Because the heat radiation belongs to electromagnetic radiation, the common fiber cement pressure plate or calcium silicate plate has transparency to the heat radiation, and the thick wall body can only block 5-10% of the heat radiation entering the room. The air conditioner needs to be started with a large amount of energy consumption in summer to solve the problem of indoor cooling. In hot summer and cold winter areas, indoor heat radiation in winter can be lost to the outdoor through walls, window glass, roofs and the like, and the heat supply quantity needs to be greatly increased to keep the indoor proper temperature.
Currently, the commonly used external thermal insulation materials for external walls are mainly classified into organic materials (such as Polyurethane (PU)), inorganic materials (such as expanded perlite) and decoration integrated composite materials. Organic heat-insulating materials are widely used once, but are gradually eliminated due to the defects that the organic heat-insulating materials are not aging-resistant, the fire-resistant grade cannot meet the A-grade requirement and the like. The inorganic material has large volume weight, poor heat preservation and insulation efficiency, and also has a plurality of problems and defects such as brittleness and the like. The composite material can make up for the deficiencies of the materials, and provides a new opportunity for the development of wall thermal insulation materials. At present, the most widely applied decoration integrated insulation board is mainly formed by compounding a calcium silicate board and an insulation material, and a bonding anchor connection mode is adopted, but the insulation board has poor fireproof performance and freezing and thawing performance, various fire safety accidents and large-area wall falling safety accidents occur, and the problems of fire prevention and falling prevention of the outer wall of the building gradually become the primary consideration factor in the design of the building industry.
At present, the decoration integrated composite material insulation board has the defects of inconsistent material edge seams, pores, material linear expansion coefficients and the like in the composite process, and joint surfaces and the like can not avoid residual air and gas generated by chemical reaction during cementation and can form local air convection with large and small sizes. The heat insulation performance of the decorative integrated composite material heat insulation board material is obviously reduced, namely the reason why the total thickness of the whole wall is multiplied and the heat transfer coefficient of the wall is higher than 0.48 after the polyurethane board (PU) with the thickness of 50mm and the concrete shear wall (walls such as aerated concrete) and the integrated board are compounded in the external heat insulation of the external wall is adopted. Meanwhile, the residual gas can cause the quality problems of uneven cooling and heating of the outer wall, hollowing, cracking, falling and the like. How to improve the combination quality of external thermal insulation of the external wall and prevent the generation of heat convection is a new subject in the technical field of novel fireproof energy-saving thermal insulation building enclosure systems.
The requirement of a building outer wall enclosure system on having excellent fireproof, heat-preservation, heat-insulation and energy-saving performances and simultaneously being capable of adapting to large-scale industrial manufacturing and convenient assembly type construction is the requirement of novel building industrial development. The problems of high energy consumption, high pollution, fire prevention, heat preservation, energy conservation, same service life as a building structure and long-term low cost, energy conservation and environmental protection in building construction are solved thoroughly, and the problems of building energy conservation and green and environmental protection of buildings are solved fundamentally.
Therefore, aiming at the high molecular organic material insulation board, how to expand the application in the building industry and improve the fireproof performance, the mechanical performance, the installation performance and the like of the insulation board becomes an important research field in the industry.
