Embodiment 1
[0036] By weight percentage, 70% of hardwood pulp, 30% of softwood pulp, 0.10% of dioctyldimethylammonium chloride, 0.03% of hydroxyethylene diphosphoric acid, adjusted by sodium hydroxide solution with a mass concentration of 10%. When the pH value is up to 8.0, conventional beating, pulping, dilution, forming, drying, coiling and slitting are performed. Other papermaking additives (wet strength agent, dry strength agent, preservative, dispersant, deposit control agent, etc.) are added as usual. Quality Inspection:
[0037] Quality Index Test results Inhibition rate of Staphylococcus aureus in 20 minutes, % 99.99 20-minute inhibition rate of Escherichia coli, % 99.99 Inhibition rate of Candida albicans in 20 minutes, % 99.99
Embodiment 2
[0039] In terms of weight percentage, 70% of hardwood pulp, 30% of softwood pulp, 0.08% of dodecyl dimethyl ammonium chloride, 0.03% of hydroxyethylene diphosphoric acid, using 10% sodium hydroxide Adjust the pH value of the solution to 7.5, and routinely beat, mix, dilute, form, dry, coil and cut. Other papermaking aids are added conventionally. Quality Inspection:
[0040] Quality Index Test results Inhibition rate of Staphylococcus aureus in 20 minutes, % 99.99 20-minute inhibition rate of Escherichia coli, % 95.88 Inhibition rate of Candida albicans in 20 minutes, % 86.62
Embodiment 3
[0042] In terms of weight percentage, 70% of hardwood pulp, 30% of softwood pulp, 0.05% of dihexadecyl dimethyl ammonium chloride, 0.03% of hydroxyethylene diphosphoric acid, using 10% sodium hydroxide Adjust the pH value of the solution to 6.5, and routinely beat, mix, dilute, form, dry, coil and cut. Other papermaking aids are added conventionally. Quality Inspection:
[0043] Quality Index Test results Inhibition rate of Staphylococcus aureus in 20 minutes, % 93.66 20-minute inhibition rate of Escherichia coli, % 86.86 Inhibition rate of Candida albicans in 20 minutes, % 72.46

Abstract
The invention relates to body paper, in particular to antibacterial body paper. In the process of preparing the antibacterial body paper, the following components relative to the weight of oven dry stock are added: 0.05 to 0.20 percent of double alkyl quaternary ammonium salt and 0.01 to 0.10 percent of 1-hydroxy ethylidene-1,1-diphosphonic acid, wherein in the process of preparing the antibacterial body paper, a right amount of alkali can also be added, so that the pH value of the antibacterial body paper reaches 6.5 to 8.0. Compared with the prior art, the double alkyl quaternary ammonium salt is used as an antibacterial agent, the 1-hydroxy ethylidene-1,1-diphosphonic acid is used as a synergist, the pH of pulp is regulated to ensure the pH of the body paper to reach a suitable value, and then the antibacterial body paper is prepared by adopting a conventional process. The detection shows that the body paper has an excellent antibacterial effect, the bacterium secondary pollution in the production, storage and using process can be prevented and the health index of the body paper is ensured to accord with the requirement.
Description
technical field [0001] The invention relates to a base paper, in particular to an antibacterial base paper. Background technique [0002] As one of the commonly used materials, paper materials are widely used in fields closely related to life, such as medical treatment, food packaging, literature collection, building decoration, etc. People may come into contact with paper everywhere in their lives. Therefore, in order to prevent various diseases caused by the spread of harmful bacteria during the use of paper and protect human health, it is of great significance to research and develop household and industrial papers with antibacterial properties. Antibacterial is a general term, including sterilization, sterilization, disinfection, antibacterial, antiseptic, etc. Antibacterial paper is paper with antibacterial function. Specifically, it refers to various functional papers with the ability to inhibit bacteria and mold. It is a comprehensive concept. [0003] According to ...
