Abstract

The invention discloses matt textured paper with high layer-to-layer bonding strength and a preparation method of the paper. The matt textured paper with the high layer-to-layer bonding strength comprises slurry and an auxiliary agent; the slurry comprises the following components in percentages by mass: 80-90% of bleached softwood pulp and 10-20% of bleached hardwood pulp; and the auxiliary agentcomprises the following components in percentages by mass based on absolutely dry slurry: 0.6-1.6% of a wet strength agent, 0.05-0.2% of a softening agent, 0.03-0.1% of a defoaming agent, and 1.0-1.5% of light calcium carbonate. The method disclosed by the invention adopts compounding of water-based self-matting polyurethane resin and synthetic latex for gum dipping in the process of preparing the textured paper, so that the paper has matt characteristic; and the polyurethane resin has a large number of polar amino groups, so that a large number of hydrogen bonds can be formed among fibers, the impregnated textured paper has stronger bonding force, so that the type of the textured paper is enriched, and an application range of the textured paper in interior decoration, wall decoration, gift packaging and other aspects is expanded.

Description

technical field [0001] The invention belongs to the technical field of papermaking, and in particular relates to a matte textured paper with bonding strength between layers and a preparation method thereof. Background technique [0002] Masking tape is a special tape developed by 3M in the early 20th century. It was firstly used in spray paint in the automobile industry, and then widely used in the architectural decoration industry and the electronics industry, mainly for pasting, protection, fixing and packaging. In the process of masking tape processing, the base paper that is not coated with silicon and glue is called masking paper. Masking paper is a high-tech decoration and spraying paper, which is a special paper product with high technical content and high added value. [0003] With the increase of people's understanding and use of textured paper, textured paper has developed from the original use in industrial painting, architectural decoration, electronics industr...
