Matting powder-free ultra-matte skin feeling UV coating and preparation and curing method thereof

Abstract

The invention relates to a matting powder-free ultra-matte skin feeling UV coating and a preparation and a curing method thereof. The formula comprises the following components in parts by weight: 30to 40 parts of hyperbranched polyester multifunctional acrylic resin, 20 to 25 parts of modified epoxy acrylic resin, 35 to 45 parts of an active monomer, 0.5 to 2.0 parts of a photoinitiator and 0.5to 3.0 parts of an antifouling auxiliary agent. The raw materials are mixed and stirred to obtain the matting powder-free ultra-matte skin feeling UV coating. The coating prepared by the invention ismainly applied to wood material surface ultra-matte skin feeling coating and the like; the manufacturing process is simple, and a gallium lamp, a 172nm excimer lamp, a nitrogen oxygen-expelling lamp and a mercury lamp UV light source are adopted; due to the fact that the ultraviolet output energy of the 172nm excimer lamp is concentrated, the ultraviolet output intensity is high and can reach 100mW / cm<2>, expensive matte powder and skin feeling auxiliaries are not needed, after a coating film is cured, the gloss of matte is below 2 degrees (60 degrees), and the coating film is good in skin feeling, stain-resistant and scratch-resistant.

Description

technical field [0001] The invention relates to a preparation method of an ultra-matte skin-feeling UV paint without matting powder, in particular to a special UV paint for super-matte skin-feel decoration on the surface of wooden boards. Background technique [0002] At present, there is no production of ultra-matte skin-feeling UV coatings without matting powder in my country. Facts have proved that ultra-matte UV coatings without matting powder have special requirements, and are now widely used in wood-based panels. Super-matte UV coatings containing matting powder , such paint defects: [0003] 1. In order to achieve the ultra-dumb effect, a large amount of matting powder must be used, and the hand feel is uncomfortable. [0004] 2. The matting powder is a nano-scale ultrafine powder, which will generate flying dust when used, which will cause great damage to the respiratory tract. [0005] 3. Matting powder has thickening and thixotropy, and the viscosity of the coatin...

Problems solved by technology

[0007] The purpose of the invention is to overcome above-mentioned weak point, thereby provide a kind of method for preparing the ultra-dull skin-feeling UV coating of exempting from matting powder, solve the problem that the original matte UV coating cannot realize the glossiness of matte below 2 (60 degree angle ), skin feel, stain resistance, scratch resistance
