Embodiment Construction

[0025] A preparation method of mineral fiber printing paper with excellent printing adaptability, comprising the following steps:

[0026] (1) Preparation of cationic modified starch:

[0027] Add 6 parts of starch, 6 parts of acrylic acid and 0.6 parts of 0.01mol / L cerium ammonium nitrate aqueous solution to the reaction tank, react at 80°C for 2 hours, let it stand and cool to 45°C, add 0.3 parts of ammonium persulfate, and fill with nitrogen Protection, control the temperature at 45°C, add 8 parts of acrylamide monomer solution dropwise to the reaction system, complete the dropwise addition within 30 minutes, continue stirring for 5 hours, and pour out the solution after the polymerization reaction is complete;

[0028] (2) Superfine crushing:

[0029] After mixing 20 parts of activated sepiolite and 30 parts of wollastonite, use an ultra-fine airflow mill to grind, add 7 parts of sodium hexametaphosphate as a grinding aid, process for 3 hours, feed pressure 0.8MPa, and gr...

Abstract

The invention discloses a method for preparing mineral fiber printing paper with excellent printing applicability. According to the method, activated sepiolite and wollastonite are subjected to superfine crushing, so that superfine powder of a large length-diameter ratio can be prepared, crystal form protection can be facilitated, a mineral fiber has a relatively large specific surface area, excellent adsorption properties for printing ink are achieved, and then the paper has excellent printing applicability; in addition, the mineral fiber is coated by modified starch, so that packing can be well combined with a plant fiber, the packing retention is improved, and the strength of paper is improved; the modified starch used in the method belongs to organic humidity control materials, is capable of regulating the relative humidity of a system in the paper making process and eliminating static electricity of paper, and has the advantages that paper shrinkage is reduced, and printing applicability is improved.

Description

technical field [0001] The invention relates to the field of papermaking, in particular to a preparation method of mineral fiber printing paper with excellent printing adaptability. Background technique [0002] Paper is a necessity for human production and life. The increasing demand for paper in my country has caused the paper industry to face a serious problem of wood pulp supply shortage. Therefore, it has become the dream of the paper industry to seek low prices and partially replace plant fibers. Mineral fibers such as sepiolite fibers and wollastonite fibers have a similar fiber structure to plant fibers. Therefore, it is of great significance to use mineral fibers to replace part of plant fibers for papermaking. [0003] Compared with traditional paper-making fillers, research on wollastonite is currently less. Wollastonite filler is a new type of mineral fiber. Its particles have a unique fibrous shape and can interweave with plant fibers to form a "plant fiber-mine...
