Abstract
The invention discloses degradable aqueous antibacterial gloss oil and a preparation method thereof, wherein the gloss oil is prepared from the following raw materials in parts by weight: 60-70 parts of degradable resin, 1-3 parts of wetting agent, 0.1-0.3 part of flatting agent, 3-4.8 parts of cosolvent, 0.2-0.4 part of wax assistant, 0.06-0.1 part of defoamer and 24.92-31.6 parts of purified water; the degradable aqueous antibacterial gloss oil has the physical tolerance of the traditional gloss oil: the tape stripping resistance, the water resistance and the oil resistance are good; the alcohol slow-release paper has the function of slowly releasing alcohol, can be applied to the field of packaging and printing of fresh food materials, prolongs the shelf life of food, and keeps the quality of nutrition and freshness; the biodegradable plastic film has the biodegradation performance, can be biodegraded in a fertilizer stacking mode, has the degradation rate close to 100 percent, and has wide market prospect in the field of food packaging and printing.
Description
Technical Field
The invention relates to water-based varnish and a preparation method thereof, in particular to degradable water-based antibacterial varnish and a preparation method thereof.
Background
At present, the use of plastic materials and products is increasingly widespread, and the problems of environmental protection brought by the traditional plastic industry and resource shortage based on the petroleum industry are increasingly highlighted. In the field of package printing, the main resin component in common ink and gloss oil is made of non-degradable material, so that the problem of persistent pollution to the environment is solved. The execution of the domestic 'plastic limit order' puts higher requirements on food printing and packaging, and the research and application of degradable printing consumables become the development trend and the focus of the packaging and printing field.
On the other hand, the conventional food package uses an inert packaging material, which is mainly used to keep the quality of the packaged food relatively isolated from the outside by physical means. However, with the large-scale development of integrated technologies of food processing, transportation and storage, the circulation of food is spread all over the world, and it is required to not only prolong the shelf life of food but also maintain the quality of nutrition and freshness. Therefore, the antibacterial requirements of food packaging are becoming more and more stringent.
Disclosure of Invention
Aiming at the defects in the prior art, the invention provides degradable aqueous antibacterial gloss oil and a preparation method thereof, and the degradable aqueous antibacterial gloss oil has wide market prospect in the field of food packaging printing.
