A kind of UV gloss oil and preparation method thereof
Technical field
The present invention relates to a kind of UV (abbreviation of Ultra viole, promptly ultraviolet ray below all is called UV) gloss oil, particularly exempt from the UV gloss oil that feels secure, promptly the paper printing matter after the printing is directly carried out the UV glazing, and the preparation method of this UV gloss oil.
Background technology
Printing coating can strengthen the light fastness of printing ink, increases the ink lay solar heat protection, and moistureproof ability plays the effect that the protection trace beautifies the products substitution overlay film.
The UV glazing is meant and utilizes ultraviolet ray that gloss oil is carried out hardening with radiation that gloss oil solidifies rapidly, for printed matter brings high gloss, and prevents scratch.
The UV glazing rises rapidly and on many products, has much and replaces gesture plastic film coated and the solvent-borne type glazing, and this depends primarily on the following characteristics that itself have:
1) UV gloss oil solvent is few, and the organic volatile quantity discharged is also few, has therefore reduced atmospheric pollution, has improved Working environment, has also reduced the danger of presence of fire;
2) the UV gloss oil does not contain solvent, does not need heat energy during curing, and it solidifies required energy consumption and has only about 20% of infrared curing type oil polish.
3) printed matter after the UV glazing process is handled, color is obviously bright-coloured beautiful than other working methods, and the coating after solidifying is wear-resisting, has more resistance to chemical reagents and chemical resistant properties, and good stability can water and ethanol scouring.
4) defective that can avoid plastic film coated technology often to occur, the phenomenons such as wrinkling delamination of bubbling like alice, UV glazing product adhesion can stack after the curing and is placed with profit and opens back working procedure processing operations such as bookbinding.
UV gloss oil in the market mostly since with the not anti-adhesive tape tearing of the sticking power of printing-ink, need with the supporting use of oil at the bottom of the water-based, i.e. oil at the bottom of coating one deck water-based on the printed matter earlier; And then carry out the UV glazing; Obtain the brightness of UV glazing printed matter like this, fastness is all fine, also brings a problem but do like this; Promptly need two procedures, increased operating cost.
Summary of the invention
The object of the invention provides a kind of UV gloss oil to the problems referred to above exactly, and this UV gloss oil can be removed the bottoming step from, only needs one procedure, has practiced thrift operating cost, has increased working efficiency.
