Preparation method of bobbin paper

Abstract

The invention discloses a method for preparing bobbin paper, which comprises the following weight ratios: 15-26 parts of bagasse pulp, 8-15 parts of fluff fiber, 28-39 parts of banana stem pulp, and then 15-26 parts of bagasse pulp, Put 8-15 parts of fluff fiber and 28-39 parts of banana stalk pulp into the mixer and stir fully, and raise the temperature to 60°C to activate the internal cellulose, and then go through screen separation, filter cleaning, fiber grinding, dehydration and separation The step of machine dehydration, and then add the following weight ratio: 17-32 parts of American waste paper, 35-52 parts of domestic waste paper, and add water to dilute, the ratio of slurry to water is 3-8:5-12, and then add papermaking Additives and fillers, and heated and stirred, heated to 70 ° C, and then processed, dried and cut into the required bobbin paper. The preparation method of the bobbin paper in the present invention has the advantages of low production cost and good product quality. , The advantage of increasing the value of pulp.

Description

technical field [0001] The invention relates to the field of industrial paper, in particular to a method for preparing bobbin paper. Background technique [0002] Tube paper is mainly used in the production of cores and pipes, industrial tubes, mulch tubes, fireworks tubes, textile tubes, spiral tubes, pagoda tubes, parallel tubes, various paper corners, cartons, honeycomb cardboard, etc. Compared with other types of paper, the cost of pulp required is relatively low. Most of them are made of various waste paper pulp or biological raw material pulp, and no tree pulp is required. The main purpose of the bobbin paper is not to be used in high-demand environments. Therefore, bobbin paper does not have very high requirements for raw materials and manufacturing processes, and some waste residues and waste paper can be reprocessed to reduce production costs, and at the same time reduce the consumption of logs and protect the environment. [0003] The pulp used in the existing bob...

Problems solved by technology

[0003] The pulp used in the existing bobbin paper is mainly made of waste paper, and the material cost is relatively low. However, some manufacturers can add various fillers to the pulp in order to further reduce the cost. Such as stone powder, porcelain clay, calcium carbonate, titanium dioxide and iron oxide yellow pigment, etc., the filler is controlled within a certain range to improve the performance of the paper, and some manufacturers add it in proportion to the cost regardless of the quality of the paper, resulting in the production. The quality of bobbin paper has become very poor, and the grade has become lower. In the field of papermaking industry, the vicious price competition of various enterprises has led to a vicious circle, which makes the quality of paper worse and worse, greatly destroying industry rules and disrupting the market. Therefore, The need for an inexpensive and reasonably priced alternative to fillers allows for a steady increase in the quality of bobbin paper
