Embodiment 1

[0024] (1) Take a certain amount of nanocellulose and mix it with deionized water to obtain a 0.01% (w / w) nanocellulose suspension;

[0025] (2) Weigh a certain amount of antibacterial agent and deionized water and mix evenly to obtain a 0.1% (w / w) transparent solution, add 1% (w / w) deodorant to the above solution, stir at room temperature for 10 minutes, and obtain an antibacterial deodorant finishing agent;

[0026] (3) Add 0.05% (w / w) wet strength agent to the pulp fiber, stir for 1min, then add nano-cellulose suspension and antibacterial and deodorant finishing agent, stir for 1min, mix well, after papermaking, pressing and drying , to obtain paper-based functional materials.

Embodiment 2

[0028] (1) Take a certain amount of nanocellulose and mix it with deionized water to obtain a 10% (w / w) nanocellulose suspension;

[0029] (2) Take a certain amount of antibacterial agent and deionized water and mix evenly to obtain a 15% (w / w) transparent solution, add 15% (w / w) deodorant to the above solution, stir at room temperature for 10 minutes, and obtain an antibacterial deodorant finishing agent;

[0030] (3) Add the antibacterial and deodorant finishing agent prepared above to the nanocellulose suspension, and mix evenly to obtain a composite finishing agent; spray one side of the paper, and place the sprayed paper in an 80° C. dryer for 5 minutes, A paper-based functional material is obtained.

Embodiment 3

[0032] (1) Take a certain amount of nanocellulose and mix it with deionized water to obtain a 15% (w / w) nanocellulose suspension;

[0033] (2) Take a certain amount of antibacterial agent and deionized water and mix evenly to obtain a 20% (w / w) transparent solution, add 20% (w / w) deodorant to the above solution, stir at room temperature for 40min, and obtain an antibacterial deodorant finishing agent;

[0034] (3) The antibacterial and deodorant finishing agent prepared above is added to the nanocellulose suspension, and mixed uniformly to obtain a composite finishing agent; the paper is sprayed, and the spraying is carried out twice. First, after spraying one side of the paper, place it in the Dry in a drying cylinder at 80°C until it is 80% dry. After standing for 30 minutes, spray the other side of the paper, and dry the sprayed paper at 110°C to obtain a paper-based functional material.

Abstract

The invention discloses a paper-based functional material and a preparation method thereof. An antibacterial agent, a deodorant and nanocellulose are combined physically and chemically to prepare a composite finishing agent; the composite finishing agent is added into pulp or sprayed, subjected to surface coating, impregnated and the like, so that the paper-based functional material can be prepared. The paper-based functional material is high in strength, good in air permeability, high in water absorption speed and good in antibacterial and deodorizing effects, can be used as a base material of wet tissues, wiping paper, toilet paper and the like, can also be used as a composite layer of hygienic product materials, and achieves the effects of strong moisture absorption, long-term bacteriostasis and deodorization. Compared with performance of an original material, the wet strength of the paper-based functional material added with the composite finishing agent is improved by 70%; the bacteriostasis rate of the paper-based functional material for escherichia coli, staphylococcus aureus and fungi is 99% or above; and the NH3 removal rate of the paper-based functional material can reach94%.

Description

technical field [0001] The invention relates to the field of household paper production, in particular to a paper-based functional material and a preparation method thereof. Background technique [0002] Household paper mainly includes roll paper, facial tissue, toilet paper and kitchen paper, etc. Some products of wet wipes and wipes in sanitary products use paper-based materials as the base material, and they are used as the material for the core layer of sanitary napkins and diapers. The absorbent backing paper is also made of paper-based material. With the development of the economy and the improvement of people's living standards, people pay more and more attention to the comfort and functionality of household paper and sanitary products. For comfort, users pay more attention to the softness and skin-friendly properties of paper-based materials; for functionality, more and more attention is paid to the antibacterial and deodorizing functions of paper-based materials. ...
