Description
Technical Field
The invention relates to a preparation method of an organic-inorganic composite thermal insulation material in the field of thermal insulation materials.
Background
The materials used in the field of heat insulation materials at present are inorganic fibers, organic foaming materials and inorganic non-metallic materials, and the heat insulation properties are different due to the fact that the properties of the materials are different, and a plurality of defects are exposed when the materials are used in the field of high temperature. Especially, the fiber heat-insulating material has large space gaps, and is easy to enter air to form a cold and hot bridge. The inorganic non-metal heat-insulating material takes microporous silicate as a main body, the silicate body has poor heat-insulating property, and heat conduction can be blocked only through the inner pore cavity, so that the heat conductivity coefficient is high. Polyurethane and polystyrene foams in organic foams have low bulk thermal conductivity, but cannot withstand high temperatures, and are susceptible to aging and fire. Since the above general-purpose materials have various disadvantages, it is a problem to be studied how to adopt a composite of an inorganic nonmetallic material and an organic foam material to impart high-temperature resistance.

the inorganic composite thermal insulation material is prepared through a compounding process of magnesia cement sizing material, brucite fiber, chopped glass fiber and polystyrene foam particles.
The positive effects are as follows: the invention adopts magnesia cement as a cementing material, adopts a thermal insulation material prepared by mixing brucite fiber, chopped glass wool and foamed polystyrene particles, and forms a structural body by gluing the magnesia cement. The heat-insulating material adopts the combination of organic and inorganic materials, so that the heat-insulating material has the advantages of good heat-insulating effect, low cost and easy manufacture. The method is suitable for being used as a manufacturing method of a novel composite heat-insulating material.
