Abstract

The invention discloses a polyurethane-modified decorative sheet and a preparation method thereof. The decorative sheet is prepared from, by weight, 30-55 parts of body paper of kraft paper, 19-40 parts of phenolic resin, 13-19 parts of sodium hydroxide, 15-35 parts of polyurethane, 8-22 parts of starch ether, 6-19 parts of cellulose, 11-23 parts of quartz sand, 11-25 parts of calcium carbonate, 6-19 parts of magnesium chloride, 3-15 parts of magnesium oxide, 4-17 parts of aluminum oxide, 4-11 parts of glass fiber and 2-7 parts of montmorillonite. According to the polyurethane-modified decorative sheet, functions of thermal insulation, energy conservation and decoration are integrated so that the purposes of prefabrication, standardization, diversified combination, industrialized production and assembly construction of the polyurethane-modified decorative sheet product can be achieved, and the polyurethane-modified decorative sheet has the advantages of high safety, good durability andleakage prevention.

Description

technical field [0001] The invention belongs to the field of material chemistry and relates to a decorative material, in particular to a polyurethane modified decorative board and a preparation method thereof. Background technique [0002] The traditional external wall thermal insulation system has the disadvantages of many on-site wet work procedures, low construction efficiency, unstable construction quality, poor decoration, and short service life. On the basis of the successful development of rigid polyurethane thermal insulation decorative panels, the company has conducted a comprehensive study on how rigid polyurethane thermal insulation decorative panels are applied to external wall insulation, and developed a combination of thermal insulation decorative panels, Adhesive, plastic expansion anchor bolts, aluminum load-bearing parts, foam caulking strips and sealants and other materials, such as rigid foam polyurethane thermal insulation and decorative board external wa...
