Embodiment 1

[0032] Example 1: Prepare 800 kg of mixed pulp with the ratio of 25:35:40 of coniferous wood BKP pulp, waste paper deinked pulp DIP pulp and Italian poplar APMP pulp, respectively, and add 80 kg of CaCO 3 Filler and other suitable chemical additives such as AKD, cationic starch, PAM and bentonite (total amount about 10kg) are prepared into paper stock, paper stock is made and treated by pigment surface, and each component of pigment surface treatment agent formula is by weight : CaCO 3 70 parts, kaolin 20 parts, latex 2 parts, starch 8 parts, pigment amount 6.0g / m 2 . Infrared dry soft roll calender finishing coiling, rewinding to get special pigment finishing offset paper 1000kg. The paper-making net concentration is 0.75%; the pulp-to-net speed ratio is about 1.04; the water content of the paper surface treated with the pigment is controlled at 3.0%; the water content of the finished paper is controlled at 5.5%. The prepared special pigment finishing offset paper has a qu...

Embodiment 2

[0033] Example 2: Prepare 800 kg of mixed pulp with a ratio of 20:45:35 of coniferous wood BKP pulp, waste paper deinked pulp DIP pulp and Italian poplar APMP pulp that have been beaten to an appropriate degree of knocking, and add 100 kg of CaCO 3 Filler and other appropriate chemical additives such as AKD, cationic starch, PAM and bentonite (total amount about 8kg) are formulated into paper stock, paper stock is made and treated by pigment surface, and each component of pigment surface treatment agent formula is by weight : CaCO 3 75 parts, 10 parts of kaolin, 2 parts of latex, 9 parts of starch, 2 parts of carboxymethyl cellulose CMC, 2 parts of water repellent, the amount of pigment 9.0g / m 2 . Infrared dry soft roll calender finishing coiling, rewinding to get special pigment finishing offset paper 1000kg. The paper-making net concentration is 0.80%; the pulp-to-net speed ratio is about 1.04; the water content of the paper surface treated with the pigment is controlled a...

Abstract

This invention discovers a special pigment groom hectograph paper and its preparation. It utilizes the advantages of high yields machine pulp (PRC-APMP) and deink pulp (DIP) which is well thickness and green environment. That is optimizing pigment spreading formulation, optimizing pulp to materials ratio and its wet end chemical and copy making technique to reach the white value of all bleaching chemical pulp proportioning copy paper. The advantages of the products are: better printing adaptability, better relaxation thickness, better printing effect features compared with all chemical pulp hectograph paper. It's capable of producing top grade office and printing culture special pigment groom hectograph paper which is made according to different clients' requirement and selecting different optimized features' technique for different application such as laser printing, xerography and hectograph etc. So, it's capable of decreasing all chemical pulp quantity, saving wood, protecting forest, protecting environment from pollution.

Description

1. Technical field: [0001] The invention relates to a multifunctional special pigment offset paper for cultural purposes and a manufacturing method thereof. 2. Background technology: [0002] Special pigment finishing offset paper is also called: multifunctional cultural paper. With the entry of office automation and microcomputers into households, the market demand for electrostatic copy paper, inkjet laser printing paper, etc. has doubled year by year. At present, the consumption of paper for office automation such as color inkjet laser printing paper and high-grade electrostatic copy paper in the domestic market is about 400,000 tons, most of which mainly rely on imports, or use light-weight coated paper, offset paper, and book paper to replace them. . Therefore, the development and production of a special pigment finishing offset paper that is suitable for multi-functional cultural purposes and has a relatively competitive price will surely have a good market share and...
