Embodiment 1

[0023] In terms of weight percentage, 70% of hardwood pulp, 30% of softwood pulp, and 0.6% of trialkoxysilane quaternary ammonium salt are added in the pulping tank for conventional beating, pulping, dilution, forming, drying, coiling, Divide. Other papermaking aids (wet strength agents, dry strength agents, preservatives, dispersants, deposit control agents, etc.) are added conventionally. The antibacterial and soft properties are tested as follows:

[0024] Quality Index

Embodiment 2

[0026] In terms of weight percentage, 70% of hardwood pulp, 30% of softwood pulp, 1.0% of trialkoxysilane quaternary ammonium salt, added in the pulping tank, conventional beating, pulping, dilution, forming, drying, coiling, Divide. Other papermaking aids (wet strength agents, dry strength agents, preservatives, dispersants, deposit control agents, etc.) are added conventionally. The antibacterial and soft properties are tested as follows:

Abstract

The invention discloses soft antibacterial raw paper. 0.6-1.5 percent by weight of trialkoxysilane quaternary ammonium salt relative to weight of oven dry stock is added in a process of preparing the antibacterial raw paper, wherein the structural formula of the trialkoxysilane quaternary ammonium salt is shown in the specification; R is an alkoxy group; R1 can be an alkyl group or an oxygen-containing or nitrogen-containing group; R2 can be an alkyl group with 1-20 carbon atoms; at least one of R1 and R2 is a long-chain alkyl group with 12-18 carbon atoms; and X- is acid radical negative ion. Compared with the prior art, since the trialkoxysilane quaternary ammonium salt is used as an additive to be added into paper pulp for preparing paper sheets, the paper sheets have a superior antibacterial effect to guarantee that the health indicators of the raw paper meet requirements; the paper sheets have soft characteristics; the soft antibacterial raw paper is particularly suitable for producing these paper sheets in direct contact with skin, such as handkerchiefs, napkins and beauty paper; and in addition, the trialkoxysilane quaternary ammonium salt is added into a pulp mixing tank, so that the paper pulp has the optimal adsorption efficiency to the trialkoxysilane quaternary ammonium salt.

Description

technical field [0001] The invention relates to a base paper, in particular to a soft antibacterial base paper and its application as a raw material for making paper products directly in contact with the skin. Background technique [0002] In modern society, the use of disposable household paper products such as paper handkerchiefs, napkins, beauty paper, etc. is very common. Since these paper products are in direct contact with the skin, in order to prevent the spread of harmful bacteria and cross-infection caused by the use of paper products It is of great significance to research and develop antibacterial paper with antibacterial function to protect the health of human body from various infectious diseases. [0003] Such as CN1928228A discloses a kind of antibacterial paper preparation method and its application, (paper) contains 0.001%-1% 2,4,4-trichloro-2-hydroxyl diphenyl ether and silver peroxide antibacterial components, its preparation method In order to add the an...
