Problems solved by technology

Most of the spraying processes currently on the market are solvent-based spraying first, and then high-temperature baking. This process requires strict operation. If the operation is not done properly, there are many links in the spraying process that are likely to cause harmful substances to enter the bottle. Cause certain food safety hazards, and the production process causes certain pollution to the environment

Abstract

The invention provides a powder coating for a low-temperature solidified wine bottle and a preparation method thereof, and belongs to the technical field of coatings. The preparation method comprises the following steps: mixing a bisphenol-A epoxy resin curing agent, a flatting agent, a defoaming agent, nano-grade silicon dioxide, an amide charging additive 519, a pigment and a filler at a high speed; extruding by virtue of a screw extruder; carrying out graded grinding on the extruded semi-finished product by virtue of an ACM grinding mill; and screening through a 160-180-mesh screen. According to the method, low-temperature solidified food-grade powder is coated, the powder coating is molten and solidified on the surface of a wine bottle, and the powder falling in the melting process can be recycled, so that the problem of traditional liquid coating waste can be solved; the used raw materials are environment-friendly and odorless, so that the working environment of operators can be greatly improved, and the potential hazards of occupational diseases can be reduced; and once coating of the powder coating can be 30-300mm, so that the production cost can be reduced, and the working efficiency can be improved. The powder coating is a novel environment-friendly pollution-free product.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to an environmentally friendly, odorless and recyclable low-temperature curing powder coating for wine bottles and a preparation method thereof. Background technique [0002] Paint is a kind of substance with certain toxicity, especially the paint used on wine bottles must be strictly handled. Most of the spraying processes currently on the market are solvent-based spraying first, and then high-temperature baking. This process requires strict operation. If the operation is not done properly, there are many links in the spraying process that are likely to cause harmful substances to enter the bottle. Cause certain hidden dangers of food safety, and the production process causes certain pollution to the environment. Contents of the invention [0003] In view of the above-mentioned problems existing in the prior art, the object of the present invention is to provide a k...
