Abstract

The invention relates to a method for preparing a polyurethane marble-imitated decorative material from industrial saponification waste residues. According to the method, macromolecular polyol used inthe method is polyester polyol or polyether polyol, isocyanate is used as a raw material, 3,3'-dichloro-4,4'-diaminodiphenyl methane is used as a chain extender, and industrial saponification waste residues are used as a filler. The preparation method comprises the following steps: (1) preparation of a prepolymer; (2) preparation of a chain extender component; (3) blending and molding at normal temperature; and (4) a post-curing process. According to the invention, polyurethane elastomer is used as a main raw material of the marble-imitated decorative material, and the polyurethane elastomerhas the characteristic of difficulty in breakage and overcomes the defects of easiness in breakage, difficulty in transportation and the like of conventional ceramic tiles; meanwhile, the industrial saponification waste residues are utilized, and more industrial saponification waste residues can be added under the condition of the same destructive power, so cost is saved, and environmental protection is realized; in addition, normal-temperature pouring is adopted; that is, a prepolymer component and the chain extender component are mixed and subjected to injection molding at normal temperature, so energy is saved, and environmental pollution is reduced.

Description

technical field [0001] The invention relates to a polyurethane imitation marble decorative material product made of industrial saponification waste residue and a preparation method thereof, belonging to the technical field of building decorative materials. Background technique [0002] Polyurethane imitation marble materials are rarely used as imitation tiles in the field of architectural decoration. Polyurethane imitation marble materials are mainly talc powder added to polyurethane resin as filler. The amount of talcum powder added is small, and the production cost is high. However, ceramic tiles are widely used in the construction field. Ceramic tiles are sintered at high temperature with a large amount of natural resources such as clay and quartz sand. They need to consume fossil fuels such as coal, and at the same time cause pollution to the environment. Ceramic tiles are easily broken and difficult to transport. [0003] Industrial saponification residue, as the waste ...
