Embodiment 1

[0040] The first step is to prepare the surface pulp for papermaking (including four processes):

[0041] A). The raw material of flour pulp is prepared, and 3 parts of wood pulp are selected according to the weight ratio. Wherein, the wood pulp is 75 parts of IC-II Chongqing oxygen deluded pulp produced and sold by China Chongqing Liwen Paper Co., Ltd. 10 parts of Roll-A type reel wood pulp imported from the United States and 15 parts of Solomon wood pulp imported and sold by Qingdao Sanrunxing Import and Export Co., Ltd., Qingdao City, Shandong Province, China. Pulp, reel wood pulp and Solomon wood pulp are mixed to obtain wood pulp raw materials;

[0042] B). Prepare the first pulp of flour pulp, put the wood pulp raw material obtained by step A) into the pulper through the chain plate machine and pulverize it, so that the wood pulp is dissociated into fibers, and the volume ratio of wood pulp and water is 100:5, and the obtained initial batter;

[0043] C). High-concentr...

Embodiment 2

[0063] Only change the amount of wood pulp in the step A) of the first step to make papermaking surface layer pulp into 2 parts, and change the weight parts of Chongqing oxygen delignified pulp, reel wood pulp and Solomon wood pulp to form wood pulp Number is changed into 80 parts, 8 parts and 10 parts respectively, and the volume ratio of wood pulp and water in step B) is changed into 100: 4;

[0064] Only change the parts by weight of U.S. 11# waste paper, European waste paper and China's domestic high-grade carton paper into 40 parts, 25 parts and 30 parts in the step a) of the second step of making papermaking core bottom layer pulp, Change the volume ratio of raw material and water in step b) to 100:5;

[0065] Only change the amount of the starch-based reinforcing agent in step a') of the third step to 1g / m 2 , change the amount of surface glue starch and surface sizing agent in step c') to 6.2g / m respectively 2 Paper and 0.15g / m 2 Paper, all the other are with the de...

Embodiment 3

[0067] Only change the parts by weight of the wood pulp in the step A) of the step A) of the first step to make paper pulp, and change the weight of the Chongqing oxygen delignified pulp, reel wood pulp and Solomon wood pulp that constitute the wood pulp to 4 parts. Parts by weight are changed to 77 parts, 12 parts and 10 parts respectively, and the volume ratio of wood pulp and water in step B) is changed to 100:6;

[0068] Only change the parts by weight of U.S. 11# waste paper, European waste paper and China's domestic high-grade carton paper into 30 parts, 35 parts and 40 parts in the step a) of the second step of making papermaking core bottom pulp, Change the volume ratio of raw material and water in step b) to 100: 5.5;

[0069] Only change the amount of the starch-based reinforcing agent in the step a') of the third step to 1.25g / m 2 Paper, change the amount of surface glue starch and surface sizing agent in step c') to 5g / m respectively 2 Paper and 0.16g / m 2 Paper,...

Abstract

The invention relates to kraft liner cardboard paper and a manufacturing method thereof, belonging to the technical field of packaging materials. The kraft liner cardboard paper is formed by the following raw materials in parts by weight: 30-40 parts of USA No.11 waste paper, 25-35 parts of European waste paper, 30-40 parts of Chinese domestic high-level carton paper and 2-4 parts of wood pulp. The technical scheme of the invention uses recovered waste paper imported from foreign countries and domestic waste cartons as main raw materials, so the amount of the used wood pulp is decreased by more than ten times when being compared with the prior art, and the precious timber resources are saved and the ecological environment is protected. The technological requirement of the method is not harsh, and the method is suitable for industrial production and can ensure that the technical effect of the kraft liner cardboard paper is reflected.

Description

technical field [0001] The invention belongs to the technical field of packaging materials, and in particular relates to a kind of kraft liner liner paper, and also relates to a manufacturing method of the paper. Background technique [0002] According to the definition of China National Standard GB / T13024-2003, the container board made of kraft wood pulp with two layers or one layer on the surface is kraft liner liner paper. products and quality products. Corrugated cardboard made of high-quality kraft liner liner paper is suitable for packaging such as heavy equipment, fine pharmaceutical and chemical products, valuables such as instruments and meters, and refrigerated goods; corrugated cardboard processed with first-class kraft liner liner paper It is suitable for the packaging of ordinary items; and the corrugated cardboard made of kraft liner liner paper with a grade of qualified products is called light-duty corrugated cardboard, which is suitable for the packaging of...
