Abstract

The invention provides an inorganic thermal insulation coiled material capable of being adhered to a building wall and a preparation method thereof. After a mineral fiber is loosened, an organic gluefilm material is sprayed and subjected to pre-wet-laying to be felty, an epoxy resin emulsion containing silicic acid is applied on the surface to obtain a flexible felty material, finally fly ash, hollow glass beads, infusorial earth and calcium acetate are prepared into a mixed powder, dry powder applying and coiling are carried out when the felty material is not dried, drying is carried out, and the inorganic thermal insulation coiled material capable of being adhered to the building wall can be obtained. The method has the advantages that wet-laying is performed on the mineral fiber and the epoxy resin is used for applying, thereby effectively improves the processing performance and simplifies the construction process; the silicic acid and the calcium acetate are preplanted, and calcium ions and the silicic acid are easily affected by cement and water during sticking to form calcium silicate, so that an epoxy resin layer is easily to be adhered to the wall firmly, and the durability of an insulation layer is improved.

Description

technical field [0001] The invention relates to the field of building materials, in particular to the preparation of thermal insulation materials, in particular to an inorganic thermal insulation coil material that can be attached to building walls and a preparation method. Background technique [0002] Energy shortage has become an important issue that cannot be ignored in today's world. One of the best ways to solve energy shortage is to save energy. Therefore, continuous research and development of energy-saving new materials is the country's long-term development strategy. Since building energy consumption occupies a large proportion in all energy consumption, more and more attention has been paid to it. Building energy saving mainly uses thermal insulation materials to reduce heat loss to ensure a constant indoor temperature, thereby reducing the energy used for heating or cooling. Therefore, building thermal insulation materials are widely used in building energy co...
