Description
Technical Field
The invention belongs to the field of packaging paper, and particularly relates to an antibacterial super-hydrophobic coating of packaging paper.
Background
The degradability of packaging plastics in natural environment is poor, and with the increase of white pollution caused by the packaging plastics, countries in the world call for the reduction of the use of the packaging plastics. As a substitute product of packaging plastics, the packaging paper has excellent natural degradability, thereby having wide application prospect.
The packaging paper, especially the food packaging paper, is generally required to have antibacterial performance so as to ensure that the food is protected from being damaged by bacteria during storage and transportation and ensure the safety of the food.
The production method of the antibacterial wrapping paper mainly comprises two types, one type is that the antibacterial agent is directly added into the paper making process of paper through a certain process, so that the antibacterial wrapping paper is obtained, but the combination effect of the antibacterial agent and the paper fiber is not ideal, and the antibacterial effect of the antibacterial wrapping paper is unstable. The other type is antibacterial wrapping paper obtained by modifying the surface of the wrapping paper. The antibacterial action comprises physical antibacterial action and chemical antibacterial action, wherein the physical antibacterial action means that the antibacterial effect is obtained by the special surface physical structure of the material; chemical antimicrobial means that antimicrobial effects are obtained by specific surface chemical activities of the material. Accordingly, the surface modification of the wrapping paper also includes both physical modification and chemical modification. In general, the physical modification and the chemical modification are carried out separately, and the obtained antibacterial effect is insufficient. Therefore, the invention aims to provide a physical-chemical simultaneously modified antibacterial super-hydrophobic coating for the packaging paper.
Disclosure of Invention
In order to solve the problems in the packaging paper in the prior art, the invention provides an antibacterial super-hydrophobic coating of the packaging paper and a preparation method thereof.
A preparation method of an antibacterial super-hydrophobic coating of packaging paper comprises the following steps:
(1) preparing clean, dry and flat packaging paper for later use;
(2) preparing a coating solution, dissolving titanate, rosin modified alkyd resin and hydroxypropyl starch in absolute ethyl alcohol, and uniformly stirring;
(3) and (3) uniformly coating the coating solution prepared in the step (2) on the surface of the packaging paper, standing for a period of time, volatilizing part of solvent ethanol, spraying deionized water on the surface of the packaging paper coated with the coating solution, performing in-situ hydrolysis on the surface, and drying after the hydrolysis reaction is complete.
In the standing process, part of solvent ethanol is volatilized, and meanwhile, under the combined action of coupling agent titanate and adhesive hydroxypropyl starch, rosin modified alkyd resin in the coating solution interacts with fibers on the surface of the packaging paper to form a stable semi-dry adhesive coating on the surface of the packaging paper. Deionized water is used as a hydrolytic agent, which can promote the hydrolysis of titanate on the surface and generate nano titanium dioxide particles in situ on the surface of the packaging paper. Because the nano titanium dioxide particles are generated in situ on the surface of the semi-dry adhesive coating, part of the nano titanium dioxide particles can float on the surface of the semi-dry adhesive coating, after drying treatment, the surface of the obtained coating has uniformly distributed nano mastoid structures, and the nano mastoid structures are matched with the micron-scale surface roughness of the coating, so that the surface of the coating presents super-hydrophobicity. Generally, the breeding of bacteria generally needs a humid environment, and the super-hydrophobicity ensures that water cannot adhere to the surface of the packing paper, so that the breeding of bacteria on the surface of the packing paper is hindered. In addition, the nano titanium dioxide particles obtained by titanate in-situ hydrolysis have antibacterial and photocatalytic effects.
Further, in order to obtain a coating excellent in antibacterial and superhydrophobic properties, the ratio of titanate, rosin-modified alkyd resin and hydroxypropyl starch is preferably titanate: rosin-modified alkyd resin: hydroxypropyl starch = (20-100 g): (20-100 g): (10-30 g).
Wherein the titanate is selected from one or more of tetrabutyl titanate, isopropyl triisostearate, tetraisopropyl di (dioctyl phosphite acyloxy) titanate, isopropoxy di-oleic acyloxy (dioctyl phosphate acyloxy) titanate and bis (acetylacetone) isobutoxy isopropoxy titanate.
Further, in the step (3), the standing time is 3 to 5 minutes.
Further, in the step (3), the mass ratio of the coating amount of the wrapping paper surface coating solution to the spraying amount of the sprayed deionized water is (1-3): 1.
The invention has the following advantages:
1. the rosin modified alkyd resin is directly used as a raw material, and a coupling agent titanate and an adhesive hydroxypropyl starch are matched, so that a stable adhesive coating can be formed on the surface of the packaging paper, and the finally obtained antibacterial super-hydrophobic coating is compact and stable.
2. Through titanate in-situ hydrolysis, a nano mastoid structure is obtained on the surface of the coating, and the micron-scale surface roughness of the coating is matched, so that the surface of the coating presents super-hydrophobicity, and further the breeding of bacteria on the surface of the packaging paper is hindered.
3. The nano titanium dioxide particles obtained by titanate in-situ hydrolysis have antibacterial and photocatalytic effects, and the antibacterial effect of the packaging paper can be enhanced by matching with the super-hydrophobic surface.

Comparative example
Taking the example 1 as a reference, the nano titanium dioxide is directly used as a raw material to replace titanate in the nano titanium dioxide, the nano titanium dioxide is dispersed in a solution dissolved with rosin modified alkyd resin and hydroxypropyl starch, and then the nano titanium dioxide is coated on the surface of the packaging paper, and after standing for 4 minutes, drying and curing are carried out.
The wrapping papers coated with the antibacterial superhydrophobic coatings prepared in examples 1-5 and comparative examples were subjected to antibacterial effect and superhydrophobic effect tests. In the antibacterial effect test, escherichia coli is used as a strain, the packaging paper is placed in a vessel cultured with the escherichia coli, after 24 hours, the growth condition of bacteria on the surface of the packaging paper is observed, and the area proportion of the surface of the packaging paper without the bacteria is recorded. In the super-hydrophobic effect test, the water contact angle of various wrapping papers is measured. The overall test results are given in the following table:
| antibacterial Effect (%) | Contact angle (°) | |
| Example 1 | 99% | 152 |
| Example 2 | 98% | 151 |
| Example 3 | 99% | 153 |
| Example 4 | 99% | 152 |
| Example 5 | 99% | 151 |
| Comparative example | 93% | 128 |
As can be seen from the above table, the antibacterial super-hydrophobic coating of the packaging paper prepared by the invention has excellent antibacterial effect and super-hydrophobic property. In contrast, the antibacterial component nano titanium dioxide is directly dispersed in the ethanol solution as the coating raw material, and the finally prepared coating has certain hydrophobicity but cannot achieve the super-hydrophobic effect. The reason is that the nano titanium dioxide particles are dispersed in the coating solution in advance, and the nano titanium dioxide particles are coated in the coating along with the drying and curing of the coated coating solution, so that an effective nano papilla structure is not formed on the surface of the coating, and the nano titanium dioxide particles do not have a super-hydrophobic characteristic. Moreover, as the nano titanium dioxide particles are coated inside the coating, the antibacterial effect and the photocatalytic effect of the nano titanium dioxide particles are partially limited, so that the antibacterial effect of the whole packaging paper is slightly insufficient.
