Automotive UV (Ultraviolet) light-cured camouflage coating and preparation method thereof

Abstract

The invention discloses an automotive UV (Ultraviolet) light-cured camouflage coating and a preparation method thereof. The camouflage coating comprises a UV light-cured resin, a reactive diluent, a camouflage paint composition, addition agents and a photoinitiator, wherein the UV light-cured resin is formed by four-functionality urethane acrylates and epoxy acrylates; the reactive diluent is formed by pentaerythritol tetraacrylate (PETA) and triethylene glycol divinyl ether (DVE-3); the addition agents comprise an accelerant, a coupling agent, a flatting agent, defoaming agent and extinction powder; the photoinitiator is formed by Irgacure651 and 2-chloridized thioxanthone. The camouflage coating disclosed by the invention has the characteristics of rapid curing speed, energy conservation, air pollution reduction, good adhesive force, high rigidity and the like.

Description

technical field

[0001] The invention belongs to the field of coatings, and relates to a UV photocuring camouflage coating for vehicles and a preparation method thereof. Background technique

[0002] UV curing coating is an environmentally friendly and energy-saving coating that was first successfully developed and commercialized by Bayer Company in Germany in 1968. Compared with self-drying solvent-based coatings, UV-curable coatings have the characteristics of energy saving, fast curing speed, solvent-free, low pollution, less land occupation, excellent physical and chemical properties of cured coatings, and are suitable for automatic assembly line coating. In recent years, UV-curable coatings have not only gradually replaced traditional solvent-based coatings for wood and plastics, but also continue to open up new application areas, such as metal surface coatings, three-dimensional precision molding processing, laser recording materials, optical fiber and chemical fiber co...
