Problems solved by technology

[0004] Ordinary copy paper is mainly finished or coated on the surface (that is, in-machine coating) while the paper is being copied by the paper machine, but this kind of finishing (or coating) on ​​the paper machine is relatively simple and complex. Non-fine, the performance of improving the paper surface is very limited, and the surface smoothness of the produced copy paper is not high
It will cause uneven absorption of toner during copying, affect the copying clarity and copying effect, and have a great impact on the service life of the toner cartridge of the copier

Abstract

The invention discloses coated copy paper, which comprises a base paper layer and a coating applying to the surface of the base paper layer. The coating is formed by applying a coating material; the coating material is prepared from the following components in parts by weight: adhesives: 1-30 parts of carboxylic butadiene-styrene latex, 1-30 parts of modified starch, 1-30 parts of CMC (Carboxy Methylated Cellulose) and 1-30 parts of PVA (Poly Vinyl Alcohol); a brightener: 0.1-5 parts of sodium hexasulfonate; ink absorbers: 2-25 parts of ultrafine silicon dioxide, 2-25 parts of hollow microspheres and 2-25 parts of titanium dioxide; fillers: 20-60 parts of CaCO3 and 20-60 parts of kaoline; and auxiliaries: 0.1-5 parts of a cationic color fixing agent and 0.1-5 parts of a nonionic color fixing agent. The coated copy paper has the beneficial effects that a production process is simple and the production cost can be reduced, and the key technology is that the ink absorbers are applied as the core of the coating of the coated copy paper and other auxiliaries (various color fixing agents) are the special feature of the coating, and the ink absorbers and the auxiliaries play a decisive and key role in the implementation effect of the coated copy paper.

Description

technical field [0001] The invention relates to the field of copy paper, in particular to a coating-type copy paper which has the characteristics of clear copy effect, high smoothness and opacity, good ink absorption performance, superior paper appearance quality, etc., and can meet various functions. Paper and methods of making it. Background technique [0002] The cultural paper market is currently the fastest growing market for paper consumption and plays a pivotal role in my country's paper industry market. Copy paper occupies a considerable proportion in the entire cultural paper market. It is the most used and consumed office consumable. It is the ultimate embodiment of copy quality. At the same time, its quality directly affects work efficiency and quality.
