不燃性を確保するには２０％以下が望ましい。Examples of the melamine resin modifier include water-soluble or alcohol-soluble, for example, acrylic polymerizable monomers and their oligomers and thermoplastic resin emulsions. Among them, they are polymerized or condensed alone or reacted with the melamine resin. It is preferable that it can be obtained. The modifier is suitable to be added in a weight ratio of 1 to 40% with respect to the melamine resin, and is preferably 20% or less in order to ensure nonflammability.

抄され、樹脂量の少いものが不燃性に有利となる。The decorative sheet to be laminated on the front surface or the front and back surfaces of the molding sheet is a paper or printing paper having a basis weight of 15 to 200 g / m 2 made of pulp, linter, synthetic fiber, glass fiber or the like and melamine similar to the above. Resin or thermosetting acrylic resin, urethane resin, fluorine resin, etc. is 50 to 300
Thermosetting resin impregnated paper impregnated with wt% is used. As the decorative sheet, in addition to the above fibers, an inorganic component such as titanium oxide, aluminum hydroxide, calcium silicate is mixed, and a sheet having a small amount of resin is advantageous for nonflammability.

染性にすぐれた表面性能が得られる。<Effects of the Invention> The decorative material according to the present invention comprises glass, a porous sheet such as a non-woven fabric or cloth made of inorganic fibers such as alumina, melamine resin, aluminum hydroxide and a modifier for the melamine resin. Since the compound is a composite and integrated product, it not only excels in workability such as cutting and fire resistance, but also has excellent dimensional stability and is not warped and deformable. In addition, since the molding flow of the composition is extremely good due to the use of the modifier, uniform moldability and adhesiveness are secured even if the treatment rate for the sheet is low, and surface performance excellent in stain resistance is obtained. .
