Embodiment 1

[0029] Preparation of biological antibacterial agent: Put titanium dioxide and zinc oxide into a high-speed grinder and grind to micron level, then mix with other components according to the following ratio, put them into a ball mill and stir for 30 minutes at a speed of 100rpm to obtain biological antibacterial agent solution.

[0030] Polyamine polysaccharides 62

[0031] Cationic polyacrylamide 3

[0032] Titanium dioxide 6

[0033] Zinc oxide 2

[0034] copper ion 2

[0035] Iodide 0.4

[0036] Hepinitol 0.6.

[0037] According to the conventional papermaking process, raw material preparation→cooking→washing→bleaching→pulping→papermaking→pressing→drying is carried out. After the papermaking step, the paper is soaked in the biological antibacterial liquid, or the biological antibacterial liquid is evenly sprayed on the paper , the amount of biological antibacterial agent added is: the content concentration is 1200ppm / ton of dry paper, and then conventional processes s...

Embodiment 2

[0039] Prepare biological antibacterial agent according to the preparation method described in embodiment 1, the composition of biological antibacterial agent

[0040] As follows: Polyaminoglycans 78

[0041] Cationic polyacrylamide 2

[0042] Titanium dioxide 8

[0043] Zinc oxide 1

[0044] copper ion 2

[0045] Iodide 0.5

[0046] Hepinitol 0.5.

[0047] According to the conventional papermaking process, the papermaking process: raw material preparation→cooking→washing→bleaching→pulping→papermaking→pressing→drying for production, cooking at 150°C for 5 hours, and then bleaching for 1 hour, adding biological antibacterial agents to the pulp slurry , the amount of biological antibacterial agent added is: the content concentration is 800ppm / ton of dry paper, stirred at 1000rpm for 1.5 hours to beat, after beating, paper is made, and then squeezed under a pressure of 1Mpa, and the temperature is kept at 150°C. The biological antibacteri...

Abstract

A biologic antibacterial agent for effectively suppresing bacteria, viruses and microbes is proportionally prepared from polyaminopolyose, cationic polyacrylamide, TiO2, zinc oxide, Cu ions, I ions and hinokitol. A biologic antibacterial paper is prepared from said biologic antibacterial agent and paper, and can be used as packing paper, antistaling paper, wall paper, etc.

Description

technical field [0001] The present invention relates to biofunctional materials, and also relates to paper products and their preparation methods and applications. Background technique [0002] According to the analysis of relevant experts, the consumption of paper products in China is expected to be 50.31 million tons in 2005, 66.04 million tons in 2010, and 87.88 million tons in 2015. Most of the paper used is closely related to the health of the human body, such as food packaging paper, women's sanitary napkins, panty liners, baby diapers, paper drinking cups, home wallpaper, etc., either directly contact the human body, or indirectly The human body is affected. Today, with more and more advanced technology and higher production quality, people have put forward new requirements for some household paper and industrial paper, that is, antibacterial function. For example, face towels, in addition to requiring themselves to be sterile, should also have the function of killi...
