Problems solved by technology

Traditional copy paper production technology usually uses bleached chemical softwood pulp and bleached chemical hardwood pulp as the main raw materials, or adds 5-15% bleached straw pulp (or other non-wood fibers) and uses calcium carbonate or talcum powder as filler , the static bending strength of the copy paper is low, the deformation is large when printing or copying, and it is easy to warp. When printing or copying, it cannot absorb ink well, the color fastness is not good, the quality of the printed image is poor, and the color saturation stability is poor.

Abstract

The invention provides a formula and a production method of copy paper. The copy paper comprises the following components in percentage by weight: 5-10 percent of bleached softwood pulp, 3-5 percent of polylactic acid fiber, 20-40 percent of bleached hardwood pulp, 10-20 percent of alkaline peroxide mechanical pulp, 30-45 percent of straw pulp, 2-3 percent of a powdered ink adhesive agent, 0.2-0.5 percent of water solidification resin, and 3-5 percent of sodium polyacrylate. The production method comprises the following steps: pulping, proportioning, papermaking and forming, surface sizing, rewinding, cutting-sorting, and packaging for forming.

Description

technical field [0001] The invention belongs to the technical field of papermaking, and in particular relates to a formula of copy paper and a production method thereof. Background technique [0002] China is a big paper-making country. In 2011 and 2012, the output exceeded 100 million tons for two consecutive years, ranking first in the world. The amount of wood pulp alone is more than 20 million tons per year, and copy paper is a paper type that requires high technical indicators among these paper products. Traditional copy paper production technology usually uses bleached chemical softwood pulp and bleached chemical hardwood pulp as the main raw materials, or adds 5 to 15% bleached straw pulp (or other non-wood fibers) and uses calcium carbonate or talcum powder as filler , The static bending strength of the copy paper is low, the deformation is large when printing or copying, and it is easy to warp. When printing or copying, it cannot absorb ink well, the color fastness...
