[0002] Household paper is paper for daily consumption. It is generally produced with all-wood pulp and requires safety and hygiene. It is an indispensable sanitary product for home, travel and catering. In order to enhance the antibacterial ability of household paper, bamboo fiber household paper should be used However, the recognition of antibacterial effect is not high. The research and development of high-efficiency antibacterial household paper will bring huge economic and social benefits, so it is extremely important to develop household paper products with stronger antibacterial effect
The Chinese patent with application number 2020105640438 discloses a bacteriostatic facial tissue containing natural bactericidal ingredients and its preparation method and application. The antibacterial composition made by mixing propylene glycol and water causes a large amount of composition to be used, and the antibacterial facial tissue is obtained by spraying the antibacterial composition evenly on the facial tissue. Since the antibacterial composition is only sprayed on the surface of the paper, it cannot penetrate into the paper Inside, only the surface has antibacterial properties, and the antibacterial effect is unstable

Abstract

The invention relates to a preparation method of bacteriostatic household paper. The preparation method sequentially comprises the following steps: obtaining a paper sample, sterilizing the paper sample, soaking the paper sample in a benzalkonium bromide solution, disinfecting, obtaining a culture medium, clinging the paper sample to the culture medium, and culturing. The method has the advantages that in the step 3, the paper sample is soaked with the benzalkonium bromide solution to transfer the benzalkonium bromide solution, so that the solution can completely soak the paper sample, and the absorption and distribution of the benzalkonium bromide solution on the paper sample are more uniform; and in the step 7, the paper sample is cultured at 37 DEG C, a good growth environment is provided for bacteria at the temperature of 37 DEG C, and the antibacterial effect of the paper sample can be obviously distinguished after culture is finished, so that the preparation method is easy to operate, expensive equipment and instruments do not need to be additionally added, the bacteriostatic agent only needs to be loaded and sprayed to the surface of paper by means of a coating or sizing device of a paper machine, and the antibacterial effect is good.

Description

Technical field[0001]The present invention relates to a method of preparing a bacteriostatic cargo paper.Background technique[0002]Domestic paper is a daily life consumption paper. It is generally produced with whole wood. It is required for safety and hygiene. It is a health supplies, travel, catering health supplies.
