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
The present invention relates to pulp technology for making paper, relate in particular to a kind of high thickness beige electrostatic copying paper and production method thereof.
Background technology
The electro-photographic paper that uses uses bleached chemical softwood pulp and bleached chemical hardwood pulp to be main raw material usually at present, or also add 5～15% bleaching straw pulp (or other non-wood fiber) or CTMP, use calcium carbonate or talcum powder as filler, use AKD, ASA (adding acidifying starch) or rosin to carry out applying glue, in paper pulp, use auxiliary materials such as brightening agent, dyestuff, starch, retention agent, use starch to carry out top sizing at paper surface and handle.
The electro-photographic paper that adopts acid applying glue applying glue technology to produce, its main applying glue raw material is rosin and aluminum sulfate, aluminum sulfate has corrosiveness to fiber, make the easy brightness reversion of paper, variable color, be difficult for long-term the maintenance, also be easy to generate sour gas during high temperature, harmful.And the common moisture of acid sized paper is higher, is 8～10%, and thickness is low, deflection is poor, easy paperboard during duplicating, wet season use duplicate easily unclear, the fuselage dust is many, paper delivery is lopsided, be with phenomenon such as paper more.Use the talcum powder as filler, particle is big, and is poor with the paper pulp fiber adhesion, causes the paper powder to come off easily, the wearing and tearing duplicator.
A large amount of bleached wood pulps that use, the fluorescent whitening agent consumption is big, becomes paper whiteness generally higher (98～110%), and reader's eyesight is caused damage.And the APMP slurry is an Alkaline Peroxide Mechanical Pulp, has outstanding advantages such as high yield, high whiteness, high strength and low pollution, low water consumption, low energy consumption, can improve the intensity of copy paper.
In addition, fibrous raw material consumption is big, and is strong to forest reserves dependence, produces a large amount of waste water, waste gas in slurrying, the bleaching process, is unfavorable for environmental protection, is unfavorable for saving energy and reduce the cost.
Summary of the invention
The object of the present invention is to provide a kind of high thickness beige electrostatic copying paper and production method thereof, can increase substantially into paper thickness, keeping under the constant prerequisite of serviceability, reduce the use of fibrous raw material, chemical adjuvant and filler, the paper web of electro-photographic paper is quantitatively reduced, the consumption that economizes in raw materials reaches energy saving purposes; Use the outward appearance of ecru simultaneously, protection reader eyesight.
The invention provides a kind of high thickness beige electrostatic copying paper, its paper pulp raw material comprises bleached chemical needle slurry and bleached chemical broad-leaved slurry, also is added with the APMP slurry, and each fibre stuff proportioning is
Bleached chemical needle slurry 10～25%
