Embodiment 1

[0034] The fiber pulp ratio is 20% bleached chemical softwood pulp, 30% bleached chemical broadleaf pulp and 50% APMP pulp. Use fourdrinier paper machine with sizer for paper production, add auxiliary materials and dyes, including calcium carbonate 100kg / ton of paper, cationic starch 10kg / ton of paper, brightener 1kg / ton of paper, AKD 10kg / ton of paper, retention aid 0.05kg / ton of paper, degasser 0.1kg / ton of paper, fungicide 0.3kg / ton Paper, dye 0.4kg / ton of paper and basic alumina (PAC) 2kg / ton of paper; the added surface treatment agent includes corn starch 45kg / ton of paper and starch modifier 0.2kg / ton of paper. This embodiment is a preferred implementation.

Embodiment 2

[0036] The fiber pulp ratio is 15% bleached chemical softwood pulp, 45% bleached chemical hardwood pulp and 40% APMP pulp. Papermaking is carried out on a fourdrinier paper machine with a sizer, adding auxiliary materials and dyes, including calcium carbonate 120kg / ton of paper, cationic starch 7kg / ton of paper, brightener 0.5kg / ton of paper, AKD 13kg / ton of paper, retention aid 0.03kg / ton of paper, degasser 0.2kg / ton of paper, fungicide 0.2kg / ton Ton of paper, dye 0.5kg / ton of paper and basic alumina (PAC) 3kg / ton of paper; the added surface treatment agent includes corn starch 40kg / ton of paper and starch modifier 0.3kg / ton of paper.

Embodiment 3

[0038] The fiber pulp ratio is 25% of bleached chemical softwood pulp, 45% of bleached chemical hardwood pulp and 30% of APMP pulp. Papermaking is carried out on a Fourdrinier paper machine with a sizer, and auxiliary materials and dyes are added, including calcium carbonate. 110kg / ton paper, cationic starch 5kg / ton paper, brightener 1kg / ton paper, AKD 10kg / ton paper, retention aid 0.03kg / ton paper, degasser 0.15kg / ton paper, bactericide 0.3kg / ton Paper, dye 0.3kg / ton of paper and basic alumina (PAC) 1kg / ton of paper; the added surface treatment agent includes corn starch 55kg / ton of paper and starch modifier 0.3kg / ton of paper.

[0039] According to the high-thickness beige electrophotographic paper produced by the method provided by the invention, its main paper-forming index is as shown in table 1 below:

Abstract

The invention relates to the technical field of paper making, and provides high thickness beige electrostatic copying paper and a production method thereof. The method comprises the following steps: using 10 to 20 percent of bleached chemical softwood pulp, 25 to 45 percent of bleached chemical hardwood pulp and 30 to 50 percent of APMP pulp as paper pulp raw materials; adding chemical accessories and dyes into a pulp compounding pool, wherein the accessories comprise alkaline aluminium oxides; using corn starch and a starch modifier as surface treatment agents; making the compounded pulp into paper through a fourdrinier with a glue blender; and then further processing through finishing equipment to obtain the paper. The production method for the high thickness beige electrostatic copying paper can greatly increase the thickness of the finished paper, reduce the consumption of fiber raw materials, the chemical accessories and fillings on the premise of maintaining the using performance unchanged, quantitatively reduce the paper web of the electrostatic copying paper and save the raw material to achieve the aim of reducing the energy consumption; and at the same time, the beige appearance can protect the eyesight of a reader.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a high-thick beige electrostatic copy paper and a production method thereof. Background technique [0002] The currently used electrostatic copy paper usually uses bleached chemical softwood pulp and bleached chemical hardwood pulp as the main raw material, or adds 5 to 15% bleached straw pulp (or other non-wood fiber) or chemical thermomechanical pulp, using carbonic acid Calcium or talcum powder is used as filler, AKD, ASA (adding acidified starch) or rosin is used for sizing, whitening agent, dye, starch, retention aid and other auxiliary raw materials are used in pulp, and starch is used for surface application on paper surface Glue treatment. [0003] Electrostatic copy paper produced by acid sizing technology, its main sizing raw materials are rosin and aluminum sulfate, aluminum sulfate has a corrosive effect on fibers, making the paper easy to turn yellow and change ...
