Ultrathin copy paper with high strength

Abstract

The invention discloses ultrathin copy paper with high strength. The copy paper is prepared from the following raw materials in parts by weight: 40-45 parts of bamboo fiber, 45-50 parts of wood fiber, 3-5 parts of kaolin, 4-8 parts of calcium carbonate, 0.5-1 part of nanometer titania, 6-10 parts of starch, 1-3 parts of borax, 4-8 parts of carboxymethylcellulose, 2-4 parts of carboxylic butadiene-styrene latex, 1-2 parts of benzotriazole, 2-4 parts of polyvinyl alcohol and 0.5-1 part of stearin. The copy paper has higher strength and stiffness, is capable of improving quality of printing and copying, and is thin, and thus waste of resources is reduced.

Description

technical field [0001] The invention belongs to the field of office supplies, and in particular relates to a high-strength ultra-thin copy paper. Background technique [0002] Ordinary copy paper is slightly insufficient, and the stiffness is not enough. During the printing or copying process, it is easy to wrinkle, causing paper jams, and increasing the failure rate of printing and copying equipment. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the invention provides a high-strength ultra-thin copy paper, which has greater strength and stiffness, improves the quality of printing and copying, is thin in thickness, and reduces waste of resources. [0004] The technical solution of the present invention is: a high-strength ultra-thin copy paper, consisting of the following raw materials in parts by weight: 40-45 parts of bamboo fiber, 45-50 parts of wood fiber, 3-5 parts of kaolin, 4-8 parts of calcium carbonate 0.5-1 part of nano-titanium...
