Abstract

The invention belongs to the field of coatings, and relates to a UV light curable camouflage paint used for a fabric, and a preparation method and an application thereof. The UV light curable camouflage paint used for the fabric comprises a light curable resin, a reactive diluent, a camouflage pigment composition and a light initiator, wherein the light curable resin is tri-functional polyurethane acrylate; the reactive diluent is trimethylolpropane triacrylate (TMPTA); and the light initiator is 2,4,6-trimethylbenzoyldiphenyl phosphine oxide (TPO). The prepared UV light curable camouflage paint has good adhesive force, good flexibility, low cost and low pollution, and can be used for preparing camouflage fabrics.

Description

technical field [0001] The invention belongs to the field of coatings, and relates to a UV light-cured camouflage camouflage coating for fabrics, a preparation method and application thereof. Background technique [0002] Compared with traditional coatings, UV light-curing coatings have become one of the fastest-growing technologies in the coatings industry today because of their fast curing speed, excellent material performance, energy saving, low pollution, and suitable for automatic assembly line coating. [0003] At present, camouflage paints for domestic fabrics use polyacrylate resins and polyurethane resins as film-forming agents. The paints contain a relatively large proportion of pigments. During use, they are scraped and dried by electric heating. This type of coating is a solvent-based coating, so it has disadvantages such as high energy consumption and serious pollution when curing to form a film. The UV light curing camouflage camouflage coating for fabrics of ...
