Abstract

The invention discloses a preparation process of a high-flame-retardant inorganic polyurethane thermal insulation foam board. The preparation process comprises the steps 1 to 7. According to the preparation process disclosed by the invention, polyether polyol, isocyanate, a catalyst, a foam stabilizer, a foaming agent and a flame retardant are used as raw materials to prepare the high-flame-retardant inorganic polyurethane thermal insulation foam board, the preparation process is simple, and the prepared high-flame-retardant inorganic polyurethane thermal insulation foam board is excellent inphysical and mechanical properties and dimensional stability; the high-flame-retardant inorganic polyurethane thermal insulation foam board is large in foaming amount, uniform and stable in foam, highin foam closed-cell rate and not prone to collapse, the use amount of the flame retardant is reduced, the production cost of enterprises is reduced, no toxic gas or dense smoke is generated when theflame retardant is combusted, and the high-flame-retardant inorganic polyurethane thermal insulation foam board meets the requirement of environmental protection.

Description

technical field [0001] The application relates to the technical field of highly flame-retardant inorganic polyurethane thermal insulation foam boards, in particular to a preparation process for highly flame-retardant inorganic polyurethane thermal insulation foam boards. Background technique [0002] Polyurethane rigid foam is mostly a closed-cell structure, which has excellent properties such as good heat insulation effect, light weight, high specific strength, and convenient construction. It also has the characteristics of sound insulation, shock resistance, electrical insulation, heat resistance, cold resistance, and solvent resistance. Widely used in insulation materials for refrigerators, freezers, cold storage, refrigerated vehicles, and insulation materials for buildings, storage tanks and pipelines. In recent years, the research on polyurethane rigid foam plastics at home and abroad has developed rapidly and has been widely used. When rigid polyurethane foam is appli...
