Preparation method of frosted raw paper

Abstract

The invention discloses a preparation method of frosted raw paper. The preparation method comprises the following process steps: firstly, mixing coniferous wood chips with broadleaved wood chips; thenperforming pulping; beating pulp again, proportioning pulp and adding auxiliaries; making wet paper sheets; performing prior drying; performing coating and glue application; performing post-drying. The frosted raw paper prepared by the method disclosed by the invention has the advantages of high quality of a product, high mechanical performance index, stable thickness, high evenness of paper sheets, and good oil-ink fixing performance; moreover, quality requirements of clients can be met.

Description

technical field [0001] The invention relates to a method for manufacturing frosted base paper, which belongs to the technical field of papermaking. Background technique [0002] Matte base paper belongs to special paper products, and it is a base paper used to make various dry grinding sandpaper. The surface of the matte base paper needs to be coated with a layer of emery with a fine and uniform particle size, and then dried and cut to make sandpaper. Matte base paper has requirements for quality indicators such as strength, wet strength, transverse shrinkage, bursting strength, tearing degree, water absorption, ink absorption, oil resistance, etc. Domestic manufacturers mostly use coniferous wood and hardwood wood for pulping and mixing. After mixing, it is copied, but due to the structure and proportion of the slurry, the use of chemical additives, and production technology, the product quality and other mechanical performance indicators are low, which cannot meet the qua...

Problems solved by technology

Matte base paper has requirements for quality indicators such as strength, wet strength, transverse shrinkage, bursting strength, tearing degree, water absorption, ink absorption, oil resistance, etc. Domestic manufacturers mostly use coniferous wood and hardwood wood for pulping and mixing. After mixing, it is copied, but due to the structure and proportion of the slurry, the use of chemical additives, and the production process technology, the product quality and other mechanical performance indicators are low, which cannot meet the quality requirements of various grades of sandpaper.

At present, high-quality sandpaper is very useful in vehicles, machinery manufacturing, precision instruments, plastic products, furniture decoration, etc., but there are few base papers for making this kind of sandpaper in the existing domestic market.
