Ink-absorption copy paper and preparation method thereof

Abstract

The invention discloses an ink-absorbing copy paper and a preparation method thereof. The ink-absorbing copy paper is composed of the following ingredients in parts by weight: 124-128 parts of bleached coniferous pulp, 870-880 parts of bleached broad-leaved pulp, 365 parts of kaolin ‑380 parts, iron yellow 189‑210 parts, iron red 10‑15 parts, super absorbent resin 25‑55 parts, toner adhesive agent 1‑2 parts, konjac gum 18‑48 parts, β‑glucan 6‑15 parts 8-19 parts of activated clay, 21-58 parts of gull gum, 5-21 parts of nano-scale aluminum silicate, 10-25 parts of camellia oil, 14-37 parts of sorbitan monopalmitate, 3-37 parts of garlic powder 15 parts, 1‑8 parts of rose essential oil, 5‑12 parts of dimethylformamide, 5‑15 parts of hydrotalcite, 10‑18 parts of sodium hexametasulfate, 7‑18 parts of caprylic acid ester, 6 parts of potassium fulvic acid ‑18 parts, curing agent 1‑4 parts, crosslinking agent 1‑5 parts. The preparation method of the ink-absorbing copy paper of the invention is simple, and the prepared paper has the advantages of high static bending strength, good ability to absorb ink, and good printing image quality.

Description

technical field [0001] The invention relates to a copy paper, in particular to an ink-absorbing copy paper and a preparation method thereof. Background technique [0002] Copy paper is the most consumed material in electrostatic copiers, and it is the embodiment of copy quality. Paper can be white or colored, and to ensure a smooth feed, the paper must be cut cleanly and precisely. Although copy paper is special paper for copiers, it has the widest range of applications and can be widely used in copiers, dot matrix printers, laser printers, inkjet printers and other equipment. The traditional copy paper production technology usually uses bleached chemical softwood pulp as the main raw material, or adds bleached straw pulp and uses calcium carbonate or talcum powder as filler. The copy paper made has low static bending strength and cannot absorb ink well. Image quality is poor. Therefore, the present invention provides an ink-absorbing copy paper and a preparation method t...
