Abstract

The invention relates to a UV (ultraviolet)-photocuring paint. The invention is characterized in that the UV-photocuring paint is prepared from the following raw materials in parts by weight: 30-35 parts of bisphenol A epoxy acrylate, 23-27 parts of aromatic polyurethane acrylate, 12-15 parts of trimethylolpropane triacrylate, 5-8 parts of tripropylene glycol diacrylate, 4-5 parts of 1-hydroxy-cyclohexylphenylketone, 1-2 parts of accelerator TETD (tetraethyl thiuram disulfide), 10-12 parts of ethyl acetate, 1-2 parts of glycide butyl ether, 2-3 parts of ethyl 2-hydroxyacrylate, 1-2 parts of p-phenylene diamine, 4-5 parts of photoinitiator 184, 1-2 parts of antioxidant 1010, 1-2 parts of titanate coupling agent TMC-TTS, 1-2 parts of crosslinking agent TAIC (triallyl isocyanurate) and 4-5 parts of dispersing aid. The paint has the film-forming efficiency of 20-23 seconds by the UV photocuring technique, and can complete film formation quickly and efficiently; and the formed film has the advantages of high surface hardness, high glossiness and high fullness, and enhances the chemical resistance, acid resistance, alkali resistance, fouling resistance, heat resistance, scalding resistance, smoke and fire resistance, aging resistance and the like.

Description

UV photo-cured coating and preparation method thereof

Technical field

The invention belongs to paint field, relate in particular to a kind of UV photo-cured coating and preparation method thereof.

Background technology

Development along with market economy, there is great variety in paint field, wherein UV coating has the advantages such as curing speed is fast, energy-conservation, ambient cure, superior performance, environmental protection, on it, ray velocity is fast, rete luminance brightness is high, and dry rear face is firm heat-resisting, and refractive power is effective, make ground produce strong main body sense, be widely used in the fields such as chemical industry, machinery, electronics light industry, communication.Due to its environment-friendly advantage, UV solidifies and to have obtained the strong support of relevant environment rules and the close attention of industry member, and UV radiation curing material is in market requirement rapid growth, and UV Radiation-curing system is just with multiple technologies combination, to overcome some defect, meet actual application.Now in printing industry; the packing that can make UV obtains some special effects: high glossiness, good ink protection feature, the slipping that can add control and rub resistance, low smell or do not have smell, low extract maybe cannot detect extract, and the provide protection to ink.

Current UV solidify material is various, but still in various degree exist some problems, such as: Organic pollutants, xanthochromia, explosive look, not low temperature resistant, the series of problems such as cost is high, corrosion-resistant, all need to continue improvement for different purposes, reduce production costs, expand purposes.
