Further, the surface of one side of the paper base layer, which is provided with the waterproof fresh-keeping coating, is a rough surface, and the waterproof fresh-keeping coating is coated on the rough surface and dried and cured to form the waterproof fresh-keeping coating.
A preparation method of fresh stained paper comprises the following steps:
a1. preparing a waterproof fresh-keeping coating, weighing the resin, the tea polyphenol, the water, the antibacterial agent, the slow-release agent and the emulsifier according to the parts by weight, and then fully mixing the resin, the tea polyphenol, the water, the antibacterial agent, the slow-release agent and the emulsifier;
a2. coating, namely coating the waterproof fresh-keeping coating on the surface of the paper substrate, wherein the coating weight is 6g/m2-10g/m2And standing at constant temperature and humidity for 2 days to obtain the fresh stained paper with the fresh-keeping function.
Further, the coating manner is one of roller coating, dip coating, painting coating and spray coating.
The invention mainly has the following beneficial effects:
the waterproof fresh-keeping coating is coated on a carrier such as a paper base layer to form a coating, can release tea polyphenol, can effectively inhibit the growth and reproduction of microorganisms, can slow down the respiration of flowers, has the effects of resisting bacteria and keeping fresh of the flowers, does not cause harm to human bodies, has a waterproof function, and can be recycled and pulped to prepare fresh flower paper, so that the fresh flower paper is degradable, green and environment-friendly and pollution-free.
Drawings
FIG. 1 is a schematic view of a partial structure of an embodiment of a flower paper of the present invention;
fig. 2 is a flow chart schematic diagram of a preparation method of fresh stained paper.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The waterproof fresh-keeping coating provided by the embodiment of the invention is prepared from the following components in parts by weight: 25-55 parts of resin, 3-5 parts of tea polyphenol, 35-65 parts of water, 0.6-9 parts of an antibacterial agent, 0.4-5 parts of a slow release agent and 0.03-1 part of an emulsifier; the preferred scheme is as follows: 45 parts of resin, 4 parts of tea polyphenol, 60 parts of water, 5 parts of an antibacterial agent, 2 parts of a slow release agent and 0.5 part of an emulsifier. Wherein, the resin is preferably at least one of acrylate copolymer, polyvinyl alcohol and ethylene-vinyl acetate copolymer, and the antibacterial agent is preferably at least one of chitosan, sodium benzoate and traditional Chinese medicine extract.
The fresh flower paper comprises a paper base layer 1, wherein at least one side surface (namely, the inner side surface and/or the outer side surface) of the paper base layer 1 is provided with a waterproof fresh-keeping coating 2, and the preferable scheme is that at least the inner side surface is provided with the waterproof fresh-keeping coating 2; the waterproof fresh-keeping coating 2 is formed by drying and curing the waterproof fresh-keeping coating. As shown in fig. 2, the specific preparation method comprises the following steps:
s100, preparing the waterproof fresh-keeping coating, weighing the resin, the tea polyphenol, the water, the antibacterial agent, the slow-release agent and the emulsifier according to the parts by weight, and then fully mixing the resin, the tea polyphenol, the water, the antibacterial agent, the slow-release agent and the emulsifier.
