Description

Novel environment-friendly fireproof heat-insulating material
Technical Field
The invention relates to a novel environment-friendly fireproof heat-insulating material.
Background
Along with the increasingly scarcity of world energy, the greenhouse effect is increasingly serious, the use of energy is reduced to the maximum extent, and the improvement of the energy use efficiency becomes an important task. Building heat-insulating materials are widely pursued as important energy-saving materials. In recent years, with the development of economy, more and more people move to cities, so that living spaces and working spaces of the cities are continuously reduced, and high-rise buildings become a method for solving the space problems. However, when the construction of urban high-rise buildings suddenly and suddenly advances and the high-rise buildings continuously emerge, the energy-saving problem and the fire safety problem of the high-rise buildings also come with the problems. High-rise building fire frequently occurs, and energy-saving and safe building decoration fireproof heat-insulating materials are urgently needed. The combustion performance of the fireproof building material refers to all physical and chemical changes generated when the fireproof building material is combusted or meets fire, and the performance is measured by the characteristics of the ignitability and flame propagation property of the surface of the material, heat generation, fuming, carbonization, weight loss, generation of toxic products and the like. China classifies the combustion performance of building materials into the following grades. A level: incombustible building material: a material that burns little. Level B1: flame-retardant building materials: the flame-retardant material has better flame-retardant effect. It is difficult to ignite in the air when meeting open fire or under the action of high temperature, is not easy to spread quickly, and can be immediately stopped after the fire source is removed. Level B2: combustible building materials: the combustible material has a certain flame-retardant effect. The fireproof thermal insulation material generally comprises an outer shell and an inner core. The two are bonded by the adhesive with strong bonding force. Although China starts late in the field, some enterprises can produce polyurethane rigid foams with flame retardant effects reaching the level of flame-retardant grade through technical means such as molecular design, structural modification, flame retardant addition and the like, and the polyurethane rigid foams are also applied to partial building heat-insulation projects. The polyurethane hard foam or the cotton rock inner core is matched with the outer steel plate or the aluminum-magnesium-manganese plate, so that good heat preservation and protection effects can be realized.
