Problems solved by technology

[0003] But there are still some deficiencies in existing UV paints: (1), traditional UV is limited to flat coating, and roller coating or curtain coating cannot be used for irregular objects; such as: objects with three-dimensional structures such as chairs must use spray
(2) Spraying is used, but there will be some "dead angles" that cannot be illuminated by ultraviolet light when dried by a UV machine, and the coating film cannot be dried
Although adding isocyanate resin (isocyanate) to the UV primer also has a drying effect, but there is a limit of "pot life"

Abstract

The invention relates to the technical field of coatings, in particular to a double-drying ultraviolet (UV) spraying matte primer and a preparation method thereof. The double-drying UV spraying matte primer comprises methylisobutylketone, n-butyl acetate, 1-hydroxy cyclohexyl phenyl ketone, polyester acrylic resin, an acrylic acid flatting agent, a silicon flatting agent, a wetting agent, an anti-yellowing agent, epoxy acrylic resin, 30 percent nitro cellulose solution, talcpowder, ethyl acetate (EAC), a silicon defoamer and activated polyamide wax. According to the double-drying UV spraying matte primer, nitro-cotton liquid is matched with UV resin, so that a double-drying effect can be achieved, and the limit of 'pot life' is avoided.

Description

Technical field: [0001] The invention relates to the technical field of coatings, in particular to a dual-dried UV spraying matt primer and a preparation method thereof. Background technique: [0002] UV paint is the English abbreviation of Ultraviolet Curing Paint, that is, ultraviolet light curing paint, also known as photoinitiated paint, light curing paint. It is automatically roll coated and drenched onto the furniture panel through machinery and equipment. Under the irradiation of ultraviolet light, it promotes the decomposition of the initiator, generates free radicals, triggers the resin reaction, and instantly cures into a film. It is currently the most environmentally friendly paint. [0003] However, the existing UV paints still have some shortcomings: (1) Traditional UV is limited to flat-panel coating, and roller coating or curtain coating cannot be used for irregular coatings; for example, three-dimensional structures such as chairs must be coated. Use spray. (2) Sp...
