Abstract
The invention discloses a beer cap adhesive coating, which comprises epoxy resin, phenolic resin, polypropylene micro-powder wax, an auxiliary agent and a mixed solvent, wherein the solid part ratio of each component is as follows: 40-70% of epoxy resin, 5-20% of phenolic resin, 2-8% of polypropylene micro-powder wax, 0.1-5% of auxiliary agent and 10-40% of mixed solvent. The beer cover adhesive coating provided by the invention is produced by replacing modified polyethylene micro-powder wax with polypropylene micro-powder wax, so that the high-temperature cooking resistance can be obviously improved, and meanwhile, the sanitary problem that a large amount of vinyl chloride monomer residues exist after the polyvinyl chloride adhesive coating is cooked at a high temperature does not exist, the beer cover adhesive coating meets the food sanitary standard, and the use requirement of the beer cover adhesive coating is met.
Description
Technical Field
The invention relates to the technical field of coatings, in particular to a coating for a beer cap adhesive.
Background
The beer cap is mainly used for sealing glass bottled wine, and in order to ensure that the sealing between the bottle opening and the beer cap is good and prevent liquid in the bottle from leaking, a soft gasket is usually additionally arranged on the inner side of the beer cap, and the additional arrangement mode is mainly to use an adhesive for adhesion. However, in the existing beer cap coating, the polyethylene adhesive coating cannot resist high-temperature cooking, and the high-temperature cooking resistant polyvinyl chloride adhesive coating has a large amount of vinyl chloride monomer residues after the adhesive coating is subjected to high-temperature cooking, so that the adhesive coating is difficult to meet the food hygiene standard. Therefore, the research on the beer cap adhesive coating which is resistant to high-temperature steaming and meets the sanitary standard is needed.
Disclosure of Invention
The invention aims to provide a beer cap adhesive coating to solve the technical problems in the background technology.
In order to solve the technical problems, the invention provides the following technical scheme: the beer cap adhesive coating comprises epoxy resin, phenolic resin, polypropylene micro-powder wax, an auxiliary agent and a mixed solvent, wherein the solid part ratio of each component is as follows:
as a preferable technical scheme of the invention, the auxiliary agent is one or two of an adhesion promoter or a catalyst.
As a preferred technical scheme of the invention, the mixed solvent is a solvent in which ketones, aromatic hydrocarbon solvent oil, alcohol ethers and esters are respectively mixed according to a certain proportion.
In a preferred embodiment of the present invention, the phenolic resin is a composition of formaldehyde and one or more of bisphenol a, phenol, cresol, and tert-butylphenol.
In a preferred embodiment of the present invention, the polypropylene micro-powder wax is a polyolefin wax modified with a carboxyl group-containing monomer.
Compared with the prior art, the invention has the beneficial effects that: according to the invention, the polypropylene micro powder wax is adopted to replace the modified polyethylene micro powder wax to produce the novel beer cap adhesive coating, so that the high-temperature cooking resistance can be obviously improved, and meanwhile, the sanitary problem that the polyvinyl chloride adhesive coating has a large amount of vinyl chloride monomer residues after high-temperature cooking is avoided, the food sanitary standard is met, and the use requirement of the beer cap adhesive coating is met.
