Problems solved by technology

However, the content of plastic in this material is relatively high, it is difficult to degrade, and it has great damage to the environment, which does not meet the needs of social development. Due to the aforementioned problems in the existing uv laser imprinting transfer varnish, it is difficult to meet the requirements

Abstract

The invention discloses UV gloss oil used for laser embossing transfer equipment. The UV gloss oil is characterized by comprising the following components in parts by weight: 2-10 parts of a light initiator, 1-5 parts of 2-ethylhexyl acrylate, 1-5 parts of a base material lubricant, 45-75 parts of a pre-polymer and 18-35 parts of a monomer, wherein the pre-polymer is amine modified polyether acrylate or ester-epoxy acrylate or superbranched polyester acrylate or a combination of the amine modified polyether acrylate and the ester-epoxy acrylate in same parts by weight; the monomer is 1,6-hexanediol diacrylate or ethoxylated trimethylolpropane triacrylate. The UV gloss oil disclosed by the invention is fast in curing speed, good in flexibility and high in glossiness and can satisfy an embossing transfer laser process, so that the laser embossing transfer effect is good.

Description

technical field [0001] The invention relates to the technical field of UV varnish, in particular to the technology of UV varnish used in laser imprint transfer equipment. Background technique [0002] UV varnish is the key carrier of laser film transfer. The existing UV varnish laser imprint transfer effect is poor: 1) There is no laser effect on the surface of the printed product or the position of the laser pattern is not fixed, the shape changes, etc. This phenomenon is also called the discount phenomenon. The main reason for this phenomenon is that if the printing plate or anilox roller of the coating unit is uneven, it will cause uneven UV varnish on the surface of the printed product, which will make the effect of the laser transferred to the surface of the printed product worse; 2 ) Rough varnish layout, the main reason for the rough varnish layout of printed products is that the viscosity of UV varnish is too low, and the temperature of UV varnish is too high or too...
