LED-UV light-cured solvent-free white paint

Abstract

The invention discloses a LED-UV light-cured solvent-free white paint. The LED-UV light-cured solvent-free white paint comprises a priming paint and a finish paint which are combined; the priming paint comprises 40 to 50% of LED-UV special-purpose modified acrylic ester, 20 to 30% of an active monomer, 4 to 6% of a LED-UV special-purpose photoinitiator, 0.5 to 1.5% of a dispersant, 0 to 1% of an antifoaming agent, 15 to 20% of titanium dioxide, and 0 to 1% of a levelling agent; the finish paint comprises 40 to 50% of LED-UV special-purpose modified acrylic ester, 20 to 30% of an active monomer, 4 to 6% of a LED-UV special-purpose photoinitiator, 0.5 to 1.5% of a dispersant, 0 to 1% of an antifoaming agent, 15 to 20% of titanium dioxide, and 0 to 1% of a levelling agent. Curing film formingof the LED-UV light-cured solvent-free white paint can be realized at room temperature; surface drying is quick; curing time is short; curing can be realized in 30min; paint film surface layer and deep layer complete curing can be realized; excellent physical and chemical performance is achieved; no smell is detected; yellowing resistance is achieved; paint cost is low; and application range is wide.

Description

technical field [0001] The invention relates to the preparation technology of an IPC classification C09D coating composition, in particular to an LED-UV photocuring solvent-free white paint. Background technique [0002] In the prior art, UV paint is ultraviolet photocurable paint, also known as photoinitiated paint or photocured paint. It is automatically rolled and showered onto the surface of the furniture board by machinery and equipment. Under the irradiation of ultraviolet light, the initiator is decomposed, free radicals are generated, the resin is reacted, and the resin is instantly cured to form a film. It is currently the most environmentally friendly paint. UV paint has been widely promoted in the furniture industry due to its high efficiency, environmental protection and good mechanical properties. [0003] The light source currently used in most UV paints is mercury lamps. Mercury lamps are large in size, slow in start-up time, and have a wide excitation spectr...

Problems solved by technology

[0006] At present, as an improved technology, for the common LED-UV photocuring solvent-free white paint at this stage, there are still some shortcomings that limit its application: deep curing is not complete, poor adhesion; surface curing caused by oxygen inhibition If it is not thorough, it will affect the adhesion of the next coating and the overall mechanical properties; the paint film is easy to yellow; the smell is strong
