Provided are a decorative sheet and a decorative material that are black when formed of an olefin-based material, have heat insulation properties, and can suppress deformation due to absorption of solar radiation. 【Solution means】In the decorative sheet 1 according to this embodiment, the colored original layer 2 is formed using a colored polyolefin-based thermoplastic resin, the transparent resin layer 4 is formed using a transparent polyolefin-based thermoplastic resin, contains an ultraviolet absorber, and the pattern layer 3 contains any one or two or more of an azomethine azo-based pigment, a perylene-based pigment, a titanium-based black pigment, a black iron oxide pigment, or a black composite oxide pigment as a black pigment. When the decorative sheet is colorimetrically measured from the outermost surface side of the sheet, the CIE1976 L * a * b * value in the color space is 15 or more and 35 or less, and when the colored original layer is colorimetrically measured alone, the CIE1976 L * value * a * b * value in the color space is 85 or more. * ​

The invention discloses a method for manufacturing a new sound-absorbing and noise-reducing material by using polyimide foam scraps, cutting and processing the scraps generated in the process of polyimide foam production into particles of different sizes, drying red iron oxide or black iron oxide or titanium dioxide as inorganic additive, and then using each component in parts by weight, putting the inorganic additive into the mixer, and then putting the polyimide foam particles of different sizes into the mixer to mix, injecting the curing agent into the mixer to continue mixing, and finally adding the catalyst into the mixer to continue mixing, putting the mixed material into the mold evenly to form the film, leaving it for 10 hours, opening the mold, taking out the product, removing the burrs, and cutting the product according to customer needs, and packing it in a carton for storage.

Even when formed using a polyvinyl chloride resin, there is provided a decorative sheet and a decorative material that are black yet have heat insulation properties and can suppress deformation due to solar radiation absorption. 【Solution means】In the decorative sheet 1, the colored original reaction layer 2 is formed of a colored polyvinyl chloride resin, the transparent resin layer 4 is formed of a transparent polyvinyl chloride resin and contains an ultraviolet absorber, and the pattern layer 3 contains any one or two or more of an azomethine azo-based pigment, a perylene-based pigment, a titanium-based black pigment, a black iron oxide pigment, or a black composite oxide pigment as a black pigment. When the decorative sheet is colorimetrically measured from the outermost surface side of the sheet, the CIE1976L * a * b * value in the color space of L * is 15 or more and 35 or less, and when the colored original reaction layer 2 is colorimetrically measured alone, the CIE1976L * a * b * value in the color space of L * is 85 or more.
