Problems solved by technology

[0004] On the other hand, the catalytic decomposition of metal ions in the existing papermaking process to hydrogen peroxide and hypochlorous acid bleaching agents affects the bleaching effect, and such as Fe 3+ The ions react with the phenolic groups in the pulp to form a deep-colored compound, which will reduce the whiteness of the pulp and increase the degree of yellowing of the pulp. Scaling of system equipment and pipelines, these metal ions cannot be effecti

Embodiment 1

[0041] An environmentally friendly high-quality paper manufacturing method in this embodiment includes the same pulping process, modulation process, papermaking process and post-processing process as the existing papermaking process. The pulping process is divided into pulping of plant fiber raw materials and bleaching. The preparation process is divided into three steps: loose pulp, beating and sizing and filling. The main improvement of the process of this embodiment is:

[0042] Add component A after the plant fiber raw material pulping step and before the bleaching step, stir for 7 minutes at a stirring speed of 170 r / min at a temperature of 34 ° C, and then let it stand for 30 minutes to transfer to the next step;

[0043] Add component B before the sizing step in the preparation process, stir for 50 minutes at a stirring speed of 10r / min at a temperature of 28°C and transfer to the next step;

[0044] The component A includes the following raw materials in parts by weigh...

Embodiment 2

[0060] An environmentally friendly high-quality paper manufacturing method in this embodiment includes the same pulping process, modulation process, papermaking process and post-processing process as the existing papermaking process. The pulping process is divided into pulping of plant fiber raw materials and bleaching. The preparation process is divided into three steps of loose pulp, beating and sizing and filling. The main improvement of the process of this embodiment is:

[0061] Add component A after the plant fiber raw material pulping step and before the bleaching step, stir at a temperature of 36°C at a stirring speed of 180r / min for 9 minutes, then let stand for 34 minutes and transfer to the next step;

[0062] Add component B before the sizing step in the preparation process, stir for 70 minutes at a stirring speed of 14r / min at a temperature of 30°C and transfer to the next step;

[0063] The component A includes the following raw materials in parts by weight:

Embodiment 3

[0079] An environmentally friendly high-quality paper manufacturing method in this embodiment includes the same pulping process, modulation process, papermaking process and post-processing process as the existing papermaking process. The pulping process is divided into pulping of plant fiber raw materials and bleaching. The preparation process is divided into three steps of loose pulp, beating and sizing and filling. The main improvement of the process of this embodiment is:

[0080] Add component A after the plant fiber raw material pulping step and before the bleaching step, stir for 7-9 minutes at a stirring speed of 175 r / min at a temperature of 35 ° C, and then stand still for 32 minutes to transfer to the next step;

[0081] Add component B before the sizing step in the preparation process, and stir for 60 minutes at a stirring speed of 12r / min at a temperature of 29°C and transfer to the next step;

[0082] The component A includes the following raw materials in parts b...

Abstract

The invention relates to the technical field of paper-making, in particular to a making method of environment-friendly high-quality paper. The environment-friendly high-quality paper is prepared froma component A and a component B, wherein the component A is prepared from diethylene triamine pentaacetic acid (DTPA), sodium dodecyl sulfonate and modified chitosan, and is added after the step of plant fiber raw material pulping and before the step of bleaching; the component B is prepared from plant polygel, pyrethrin, additive plant extracts and modified dialdehyde starch, and is added beforethe sizing step in the preparation process. The preparation method can effectively reduce the influence of metal ions on pulp bleaching, enables fibers to be better swelled up, and enables the paper to be more easily dried; furthermore, the preparation method can reduce the filament flow phenomenon, improve the strength of the paper and enhance the penetration resistance of paper sheets to hydration liquid, and also has good bacteriostasis and insect prevention effects; all the added components are non-toxic and harmless as well as safe and environmentally friendly, so that the prepared paperhas a higher practical value and a good application prospect.

Description

technical field [0001] The invention relates to the technical field of modern papermaking, in particular to an environment-friendly and high-quality paper manufacturing method. Background technique [0002] Papermaking is an important invention of the working people in ancient China. There are two forms of mechanism and manual. The mechanism is carried out continuously on the paper machine. The pulp suitable for paper quality is diluted with water to a certain concentration, and is initially dehydrated in the wire part of the paper machine to form a wet paper sheet, which is then dehydrated by pressing, and then dried into paper. [0003] On the one hand, because handmade paper is beaten manually, the fibers in the pulp are well preserved and the fibers of handmade paper can be arranged in various directions evenly; machine-made paper is beaten by machines, and the pulp fibers are broken. The longitudinal and horizontal distribution of fibers is uneven. For example, during...
