Reflective heat-insulating flexible decorative sheet and preparation method thereof

Abstract

The invention relates to the technical field of building materials, and discloses a reflective heat-insulating flexible decorative sheet. The decorative sheet comprises a surface layer and a back surface layer in sequence from the top to the bottom, wherein the surface layer comprises the following components in parts by weight: 0.5-30 parts of an acrylic emulsion or redispersible latex powder, 0-20 parts of reflective powder, 5-20 parts of hollow glass microbeads, 30-90 parts of an inorganic filler, 0-50 parts of an inorganic cementing material, 0-1 part of a water-retaining agent, 0-1 part of fibers, 2-30 parts of titanium white, and 0-5 parts of a pigment; and the back surface layer includes the following components in parts by weight: 0.5-30 parts of an acrylic emulsion or dispersiblepolymer powder, 0-20 parts of hollow glass microbeads, 0-1 part of a water retaining agent, 30-90 parts of an inorganic filler, 0-1 part of fibers, 0-30 parts of titanium white, and 0-5 parts of a pigment. The flexible decorative sheet disclosed by the invention has good reflective heat-reflective effects, is heat-preservation and thermal-insulation, has a simple production process, can realize industrialized continuous production, has low production costs and a wide application range, and can be widely used in the fields of fixture and decoration.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a reflective heat-insulating flexible decorative sheet and a manufacturing method thereof. Background technique [0002] As a building decoration material, ceramic tiles have insurmountable safety hazards when applied to exterior walls, especially high-rise buildings. Stainless steel plate decoration material has high manufacturing cost, expensive price and difficult construction. The flexible decorative sheet is an ideal building decoration material because of its light weight and certain flexibility. However, the existing flexible decorative sheet has poor reflection and heat insulation performance, and is not suitable for the application of the outer sheath of the cooling and heating pipeline, the roof of the building, and the like. [0003] Therefore, developing a flexible decorative sheet with reflective heat insulation function and its manufacturing method is a...
