Problems solved by technology

That is to say, in the existing technology, the high strength and high softness of household paper are two properties that are difficult to have at the same time. Improving one of them will lead to the deterioration of the other.
In addition, the addition of additives such as dry strength agent and softener in the existing paper manufacturing is relatively large, which not only increases the manufacturing cost, but is also not conducive to the improvement of product safety

Embodiment 1

[0021] A preparation process of household paper, comprising the following steps:

[0022] (1) Slurry refining treatment:

[0023] According to the design requirements of tissue paper, the slurry of different components is subjected to corresponding refining treatment operations. When refining each slurry, ultrasonic waves with a frequency of 46 kHz are simultaneously applied for treatment;

[0024] (2) Preparation of mixed slurry:

[0025] The slurries of different components corresponding to the refining treatment in step (1) are matched according to the corresponding mass fractions to prepare a mixed slurry for later use, and then 0.1% of the total mass of the mixed slurry is added to the mixed slurry. % dry strength agent, 0.1% glycerol, 0.03% tartaric acid, after mixing and stirring evenly, then use a microwave with a power of 600W to treat it for 40s and then use it for later use;

[0026] (3) Paper copying:

[0027] The mixed pulp treated in step (2) can be convention...

Embodiment 2

[0033] A preparation process of household paper, comprising the following steps:

[0034] (1) Slurry refining treatment:

[0035] According to the design requirements of tissue paper, the corresponding refining operations are carried out for the slurries of different components. When each slurry is refined, ultrasonic waves with a frequency of 50 kHz are applied simultaneously for processing;

[0036] (2) Preparation of mixed slurry:

[0037] The slurries of different components corresponding to the refining treatment in step (1) are matched according to the corresponding mass fractions to prepare a mixed slurry for later use, and then 1% of the total mass of the mixed slurry is added to the mixed slurry. % dry strength agent, 0.2% glycerol, 0.05% tartaric acid, mix and stir evenly, and then use a microwave with a power of 600W to treat it for 45s and then use it for later use;

[0038] (3) Paper copying:

[0039] The mixed pulp treated in step (2) can be conventionally mad...

Abstract

The invention discloses a preparation technology for paper for daily use, belonging to the field of paper-making. The preparation technology comprises the following steps: (1) grinding pulp; (2) preparing a mixed pulp; (3) manufacturing the paper sheet. The paper sheet finally prepared according to the invention is higher in strength and softness; the quality is acquired; the dosage of the added softening agent and dry strength agent is less; the preparation method is reasonable; the whole manufacturing cost is reduced by about 15%; the economic benefit and the market competitiveness of the product are promoted.

Description

technical field [0001] The invention belongs to the field of papermaking, and in particular relates to a preparation process of household paper. Background technique [0002] Facial tissue, toilet paper, napkins, kitchen paper, toilet paper and other household paper are essential consumer goods for contemporary consumers. With the improvement of living standards, people have higher and higher requirements for the softness of household paper, especially for the softness of household paper that is in contact with human skin. [0003] At present, the purpose of improving the softness of household paper is mainly achieved by adding softeners. There are two main ways to add softeners. One is to make base paper at the wet end, for example, after adding softener to the pulp. The other is to apply a certain amount of softener on the surface of the base paper by back-end coating. However, no matter which of the above methods is used to add the softener, the tensile strength and b...
