Description
Technical Field
The invention belongs to the technical field of insulation board materials, and particularly relates to a moisture-proof impact-resistant composite insulation board.
Background
China is the fastest developing country of the construction industry in the world and is a construction site everywhere in China. According to the market survey report, the global thermal insulation material is increased by 5%, China is estimated to account for 29% of the global thermal insulation in 2009-2014, and China is the country with the most demand for the thermal insulation material in the world at present. The heat insulating material for building application can be simply divided into an organic type, an inorganic type and a composite type, the production and application of the heat insulating material in nearly 15 years in China are developed at a high speed, and a plurality of products are simplified to be diversified and functionalized. The material synthesis technology and production equipment reach advanced levels, so that the product quality and the fire-proof grade are generally improved, and the method becomes an industry with complete varieties. According to the requirements of building structure characteristics, energy saving rate, safety, fire prevention and the like, various building heat-insulating materials adopt different technical measures and are widely selected and used in an energy-saving building heat-insulating system. The performance and application of various heat-insulating materials have various advantages and disadvantages, and compared with the fireproof performance of the heat-insulating material alone, the inorganic light heat-insulating material (slurry) has good fireproof performance (the combustion grade is A grade), but the application thickness of the inorganic heat-insulating material is inevitably increased and the building load is inevitably increased on the premise of achieving the same heat-insulating effect because the heat conductivity coefficient is higher. Therefore, if no measures are taken on the construction of building heat insulation, the inorganic light-weight heat insulation material can be used for external wall heat insulation in southern areas of China, and is particularly suitable for heat insulation of parts such as non-heating staircases, individual partition walls, basement ceilings or individual external heat insulation, heat bridge repair and internal and external wall composite heat insulation according to the existing 65 percent of building energy saving rate and fire prevention requirements in northern areas. The organic heat-insulating material has the advantages of small volume weight, low heat conductivity coefficient, convenient construction and the like. The flame rating of polystyrene foam (xps. eps) boards is generally B2 grade (flammable), and after flame-retardant modification, B1 grade (flame-retardant) can be achieved. However, after the polystyrene foam is heated (80 ℃), the polystyrene foam begins to soften and shrink and forms a cavity when meeting open fire. The phenolic foam and the polyurethane hard foam belong to organic thermosetting heat-insulating materials, the performance and the application method of the thermosetting heat-insulating material have many advantages, the construction technology is mature, the polyurethane hard foam has no molten drop phenomenon after being burnt, but the burning grade is mostly B32 grade, the modified polyurethane hard foam can reach B1 grade (but the oxygen index is difficult to reach 30 percent), the burning grade of the modified Polyisocyanurate (PIR) hard foam can reach B1 grade, B1 grade polyurethane hard foam and modified polyisocyanurate once the surface is carbonized in fire, no molten drop is generated, and high-toxicity dense smoke is generated. As is well known, the phenolic foam has the basic advantages of organic heat-insulating materials and particularly has the outstanding fireproof performance of inorganic heat-insulating materials, the most common phenolic foam has the combustion grade of B1 (wherein the oxygen index reaches 40 percent and is easy to reach 45 percent), and only generates charring on the surface without molten drops under the direct contact of open fire at the high temperature of 1300 ℃, so that the phenolic foam has the penetration performance of flame resistance, extremely low smoke and low toxicity. Compared with other organic mass energy heat insulation materials, the material can reduce the occurrence of fire accidents in the heat insulation construction process outside buildings or after engineering acceptance, and can effectively control the flame spread. Many fire accidents happen in the heat preservation construction process of the internal and external walls or after completion of the construction, the accidents are caused by polystyrene foam and polyurethane hard foam, but the accidents are not caused by phenolic foam together, and the phenolic foam technology enters into the substantive research from the beginning of 90 years in China at present. However, phenolic foam has the general defects of large acidity, overlarge brittleness, inconvenience in transportation and application, low pore closing rate, poor heat insulation property, high shrinkage and the like, and benzoxazine resin is not phenolic resin and is a heterocyclic structure-containing intermediate synthesized by taking phenolic compounds, aldehydes and amine compounds as raw materials. The skilled in the art needs to develop a method for preparing a moisture-proof impact-resistant composite thermal insulation board so as to meet the existing application market and performance requirements.
