Abstract

The invention relates to the field of metal decorating packaging, in particular to VOC emission-free environment-friendly UV gloss oil for laminated steel and a preparation method of the VOC emission-free environment-friendly UV gloss oil. According to the VOC emission-free environment-friendly UV gloss oil for the laminated steel, the adhesive force of the gloss oil on UV printing ink and the laminated steel reaches two or more levels, the gloss oil has high toughness while having good hardness, and all physical and chemical properties need to reach the same physical and chemical properties as those of a paint film prepared through a traditional baking process; in addition, the applicant uses gloss oil for the processing technology of the laminated steel, packaging of the laminated steelis achieved in a UV curing mode, high-temperature baking is not needed in the whole process, the defect that the laminated steel is prone to deformation in the baking process is overcome, energy is saved, VOC emission is avoided, and environmental protection is facilitated.

Description

technical field [0001] The invention relates to the field of printed iron packaging, more specifically, the invention relates to a non-VOC emission-friendly UV varnish for coated iron and a preparation method thereof. Background technique [0002] Printed iron needs to be packaged before use. The printing process generally used for the outer coating of packaging cans is the process of undercoating white curdine or primer + UV ink or thermosetting ink + traditional acrylic baking varnish. Only two times of high-temperature baking can be completely cured to obtain a paint film, which consumes a lot of resources, and a large amount of VOC emissions pollute the air, which is neither energy-saving nor environmentally friendly. The emergence of coated iron technology eliminates the use of primer or base oil. The ink can be directly printed on the coated iron, and then printed with varnish to complete the production of the paint film. And in order to avoid environmental pollution,...
