Embodiment 1

[0029] A) Ingredients, according to the weight ratio, select 60 parts of US 11# waste paper imported from the United States. The US 11# waste paper referred to here is the International Association Plumbing and Mechanical Officials (International Association Plumbing and Mechanical Officials). ) Established international standard certification norms PS-95 standard for waste corrugated box paper, the mass percentage of unqualified paper per 100 grams of waste paper in the United States 11# waste paper is <5.0% and is prohibited If the mass percentage content of the material is less than 1.0% and the moisture content is less than 12%, 30 parts of European waste paper are selected. The European waste paper referred to here is the mass percentage of miscellaneous paper per hundred grams of waste paper <29%, and the mass of impurities Recycled cardboard paper with a percentage of <1.0% and a moisture content of <12%, the miscellaneous paper referred to here is non-recycled cardboard,...

Embodiment 2

[0040] Only change the number of U.S. 11# waste paper in step A) to 45 parts, change the weight of European waste paper to 45 parts, and change the volume ratio of raw material to water in step B) to 100:4.5 , Change the amount of starch enhancer in step J) to 0.4g / m 2 Paper, change the amount of sizing agent to 2.2g / m 2 Paper and change the amount of surface gum starch to 8g / m 2 Paper and change the amount of surface sizing agent to 0.06g / m 2 paper. The rest are the same as the description of Embodiment 1.

Embodiment 3

[0042] Only change the weight parts of US 11# waste paper and European waste paper in step A) to 50 parts and 40 parts respectively, and change the volume ratio of raw material to water in step B) to 100:4, and change step J ) The amount of starch enhancer, the amount of sizing agent, the amount of surface gum starch and the amount of surface sizing agent were changed to 0.6g / m 2 Paper, 1.5g / m 2 Paper, 6g / m 2 Paper and 0.07g / m 2 paper. The rest are the same as the description of Embodiment 1.

Abstract

The invention discloses a corrugated paper and a manufacturing method thereof. The corrugated paper is composed of the raw materials according to parts by weight: 45-60 parts of USA No.11 waste paper, 30-55 parts of EOCC and 10 parts of Chinese domestic high-grade carton paper. The technical scheme provided by the invention utilizes Chinese domestic high-grade waste carton paper, USA No.11 waste paper and EOCC as raw materials, thus not only ensuring the reuse of Chinese domestic high-grade waste carton paper, embodying circular economy, saving resources, and protecting environment; meanwhile, the strength of the corrugated paper is obviously improved, and the surface is fine and beautiful and is favourable for ensuring printing effect. All the technical links of the provided manufacture method do not have rigorous requirements, so that the manufacturing method is suitable for industrial production and can fully embody the technical effect of the corrugated paper.

Description

Technical field [0001] The invention belongs to the technical field of packaging materials, in particular to a corrugated paper, and also to a manufacturing method of the corrugated paper. Background technique [0002] Corrugated paper is also customarily called corrugated paperboard. There are many reports on corrugated paperboard and corrugated paperboard manufacturing methods in the literature, especially Chinese patent documents. Chinese Patent Application Publication No. CN1876363A discloses single-wall four-layer corrugated paperboard and its manufacturing process. It is to put corrugated corrugated paper bonded together as a whole between two layers of cardboard, but neither the raw materials (recipe) of the corrugated paper nor the method for preparing the corrugated paper are given, but the ready-made corrugated paper is used. Four-layer corrugated paper. Publication No. CN101532270A recommends the lightweight flexographic preprinted color corrugated cardboard and its p...
