Problems solved by technology

[0004] The existing water-based plastic coating paint has good adhesion, hardness, high temperature resistance and light resistance, but it takes a long period for consumers to use cosmetics. During use, the barrier property of the coating on the cosmetic packaging bottle is not high. , The effective antibacterial ability is poor, so that the external harmful substances or bacteria will slowly migrate to the cosmetics in the packaging bottle through the packaging bottle, making the cosmetics polluted. Coatings for cosmetic packaging bottles are a problem to be solved

Abstract

The invention discloses paint used for cosmetic packaging bottles, and a preparation method and coating technology thereof. The paint includes waterborne resin emulsion, a filling material, an auxiliary agent, a barrier-type antibacterial agent and deionized water; the waterborne resin emulsion is formed by amino silicone oil modified acrylic resin emulsion and montmorillonite modified waterbornepolyurethane emulsion according to a mass ratio being 1 : 1-1.2 through mixing; the barrier-type antibacterial agent includes epoxy resin emulsion, a film-forming auxiliary agent, chitosan, a lotus leaf hydrophobic agent and antibacterial liquid; and the antibacterial liquid is prepared by mixing silver-loaded zeolite, eucalyptus oil and lemon oil according to a mass ratio being 1 : (0.5-0.9) : (0.6-1) to grind into particle sizes that are less than or equal to 1 [mu]m. The coating technology of the paint includes three steps which successively are surface pretreatment, primary spraying and secondary spraying. The paint has advantages of being good in barrier property and high in antibacterial property.

Description

technical field [0001] The invention relates to the technical field of packaging bottle coatings, more specifically, it relates to a coating for cosmetic packaging bottles, a preparation method and a coating process thereof. Background technique [0002] Due to the characteristics of light weight, easy processing, corrosion resistance, and abundant resources, plastics are widely used in our daily life, and gradually replace glass bottles, becoming the main material in the cosmetic packaging market. In recent years, plastic packaging has occupied 80% of cosmetic packaging materials above. At present, the materials used in plastic packaging containers for cosmetics mainly include polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), polyvinyl chloride (PVC), etc. In order to make the surface of cosmetic packaging bottles With rich color effects, it is generally sprayed with multiple layers of paint on cosmetic packaging bottles. [0003] In the prior art, ...
