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 a coating used for cosmetic packaging bottles, a preparation method and a coating process thereof. Coatings for cosmetic packaging bottles include the following components: water-based resin emulsion, fillers, additives, barrier antibacterial agents, and deionized water; the water-based resin emulsion is composed of amino silicone oil modified acrylic resin emulsion and montmorillonite modified water-based polyurethane emulsion. The mass ratio is 1:1-1.2 mixed; the barrier antibacterial agent includes the following components: epoxy resin emulsion, film-forming aid, chitosan, lotus leaf hydrophobic agent, antibacterial liquid; the antibacterial liquid is composed of a mass ratio of 1 :(0.5‑0.9): (0.6‑1) mixed with silver-loaded zeolite, eucalyptus oil and lemon oil, and ground to a particle size of ≤1 μm. The coating process of the coating used for cosmetic packaging bottles of the present invention includes three steps of surface pretreatment, primary spraying and secondary spraying. The coating used for cosmetic packaging bottles of the present invention has the advantages of good barrier property and high antibacterial performance.

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, ...
