Abstract
The invention discloses a colored UV (Ultraviolet) cured coating, which is prepared from the following raw materials in parts by weight: 35-40 parts of polyurethane acrylate, 10-12 parts of dipropylene glycol diacrylate, 1-2 parts of trimethylolpropane, 1-2 parts of tri(2-ethoxyl) isocyanurate, 3-4 parts of acrylic resin, 2-5 parts of allyl heptanoate, 1-2 parts of methoxy-4-methylphenol, 1-2 parts of selenium acetylacetonate, 3-4 parts of 2, 4, 6-trimethyl benzoyl diphenyl phosphine oxide, 1-2 parts of 2-ethylamino heptadecenyl imidazoline and 4-5 parts of dispersing auxiliary. The colored UV cured coating disclosed by the invention overcomes the problems of the existing colored UV cured coating, such as high volatility and difficulty in construction, has the advantages of low VOC (Volatile Organic Compounds), good decoration effect, good glossiness, solid color, good dispersion effect, no layering, fast curing, easy construction, simple production technology and combined flow line production, and can be used for decorating base materials, such as plastics, woodware and metals.
Description
technical field [0001] The invention belongs to the field of coatings, in particular to a colored UV photocuring coating and a preparation method thereof. Background technique [0002] With the development of the market economy, great changes have taken place in the field of coatings. Among them, UV coatings have the advantages of fast curing speed, energy saving, room temperature curing, superior performance, and environmental protection. The surface is strong and heat-resistant, and the refraction effect is good, so that the substrate has a strong sense of subject. It has been widely used in chemical industry, machinery, electronic light industry, communication and other fields. Due to its environmental protection advantages, UV curing has received strong support from relevant environmental regulations and close attention from the industry. While the market demand for UV radiation curing materials is growing rapidly, UV radiation curing systems are being combined with vari...
