Multi-layer type suede composite decorative paper, and material and parameters thereof

Abstract

The invention discloses multi-layer type suede composite decorative paper, which is a layered product. The multi-layer type suede composite decorative paper is sequentially provided with a printing stock backing paper layer (1), a lower adhesive layer (2), a printing stock core film layer (3), an upper adhesive layer (4), a printing stock surface paper layer (5), a printing ink layer (6), a suede undercoat layer (7) and a suede finishing coat layer (8) from bottom to top; a printing stock, namely composite printing paper, is formed by the printing stock backing paper layer (1), the printing stock core film layer (3), the printing stock surface paper layer (5), the upper adhesive layer (4) and the lower adhesive layer (2) in common, and a suede effect layer is formed by the suede undercoat layer (7) and the suede finishing coat layer (8) in common. Each layer adopts the following materials of whole-wood pulp woodgrained paper or printing paper, a polyethylene adhesive, a polyethylene film, oily printing oil and acrylic resin. The multi-layer type suede composite decorative paper disclosed by the invention is used for decorative veneer of artificial panels, building materials and furniture, and is good in breaking resistance and tear resistance, high in product perfectness ratio, long in service life, good in covering property, strong in water absorption, easy to dedust and resistant in scrubbing.

Description

technical field [0001] The invention relates to a decorative paper whose printing substrate is paper-film composite paper, and a coating layer is formed on the surface of the printed graphic and text, and also relates to the materials and parameters of each layer of the product. Background technique [0002] As a decorative paper on the surface of artificial boards, building materials and furniture, it has been popularized and applied in my country for about 30 years. Initially, the printing substrate was a single-layer decorative paper. Later, in order to facilitate dust removal, scrub resistance and tear resistance, it developed into a composite decorative paper coated with a protective film on the surface of the decorative paper. The material of the protective film is polyphenylene Ethylene dicarboxylate is PET glue. The temperature resistance of this glue is 120-130°C. The heat consumption during production is relatively high. The bending resistance and tear resistance o...

Initially, the printing substrate was a single-layer decorative paper. Later, in order to facilitate dust removal, scrub resistance and tear resistance, it developed into a composite decorative paper coated with a protective film on the surface of the decorative paper. The material of the protective film is polyphenylene Ethylene dicarboxylate is PET glue. The temperature resistance of this glue is 120-130°C. The heat consumption during production is relatively high. The bending resistance and tear resistance of the single-layer film are not strong enough, and the service life and service life deviation
