Abstract

The invention discloses a heat-preserving, flame-retardant, water-proof and corrosion-resistant functional gel material and a preparation method thereof. The functional gel material is prepared from polyether glycol, epoxy resin, polyisocyanates, water, a reactive flame retardant, a flame-retardant antismoke agent, a compound catalyst, a foam stabilizer and a physical foaming agent serving as raw materials through a polymerization reaction. The gel material has the characteristics of flame retardancy, corrosion resistance, waterproofness, field foaming property and the like, and can be applied in the fields of heat preserving, cold preserving and the like for various pipelines in building wall bodies, cold storage warehouses, central air conditioners, petrifaction, metallurgy and the like.

Description

technical field [0001] The invention belongs to the field of chemical industry, and in particular relates to an interpenetrating network-structured heat-preserving, flame-retardant, waterproof, and corrosion-resistant functional gel material and a preparation method thereof. Background technique [0002] The energy-saving materials used for building external insulation mainly include: polystyrene foam board (EPS and XPS), rock (mineral) wool board, glass wool felt and ultra-light polystyrene particle insulation slurry. A common feature of the above materials is that there are a large number of closed pores inside the material, and their apparent density is relatively small, which is also necessary as a thermal insulation material. Rock (mineral) wool and glass wool are sometimes collectively referred to as mineral wool, both of which are inorganic materials. Rock wool does not burn, and the price is relatively low. While meeting the thermal insulation performance, it can al...
