Problems solved by technology

However, the cellulose contained in cotton pulp is relatively pure, while wood pulp contains lignin, etc., which is very unfriendly to the environment
Obviously, the use of a large amount of wood pulp in this patent application cannot avoid environmental problems, and will also affect the use of the advantages of cotton pulp paper
[0005] In addition, for high-end household paper, the antibacterial property is a very important inspection index, while the household paper made directly from cotton pulp has limited antibacterial effect, and it is difficult to meet the high-quality requirements of household paper

Embodiment 1

[0029] A method for blending bleached cotton pulp into high-end household paper, the specific steps are as follows:

[0030] (1) First mix 0.8kg nanometer silicon dioxide and 0.15g nanometer white tourmaline powder to obtain a mixed powder, then ultrasonically disperse the mixed powder in 0.8kg volume concentration 80% ethanol aqueous solution to obtain a suspension, then stir it Add 2kg of the 80% lysine monomer premix solution at a uniform speed and drop it slowly to the suspension, continue stirring for 20 minutes after the addition, centrifuge, and dry to obtain a modified mixed powder;

[0031] (2) Get 1kg modified mixed powder and 0.2kg carbodiimide to add in 5.5kg bacterial cellulose slurry, 400W ultrasonic vibration treatment for 60 minutes, obtain premixed slurry;

[0032] (3) Then use cotton as raw material to make bleached cotton pulp, then use methyl methacrylate to partially graft the bleached cotton pulp to obtain modified cotton pulp, and finally premix 10kg of ...

Abstract

The invention provides a method for preparing high-end paper for daily use from bleached cotton pulp, which is characterized in that the bleached cotton pulp is used for preparing the high-end paper for daily use, specifically, the bleached cotton pulp is partially grafted and modified by methyl methacrylate to prepare modified cotton pulp, then the modified cotton pulp and premixed pulp mainly comprising bacterial cellulose are uniformly mixed to obtain mixed pulp, and the mixed pulp is used for preparing the high-end paper for daily use. And finally carrying out papermaking to obtain the high-end household paper. The high-end household paper obtained by the invention has the natural softness of cotton pulp paper, has good toughness and antibacterial property, conforms to the pursuit of high-quality paper of consumers, and has a wide market prospect.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a method for blending bleached cotton pulp into high-end household paper. Background technique [0002] Household paper is an indispensable sanitary wipe paper for home and out. With the improvement of people's living standards and the requirements for quality of life, more and more people are beginning to pursue the use of high-end household paper. [0003] At present, household paper is mostly made of cotton pulp, wood pulp, bamboo pulp, straw pulp, etc. Among them, cotton pulp paper is softer, and wood pulp paper is more flexible. Contact, so cotton pulp paper is more in line with the requirements of high-end household paper. However, the toughness of cotton pulp paper has a lot of room for improvement. [0004] Patent application CN110158360A discloses a household paper and its production method. The main raw materials are coniferous wood pulp, hardwood pulp, and cotton...
