Problems solved by technology

However, the ink contains at least 20%-70% organic solvent VOC, and the volatilization of the organic solvent is used to form the drying of the ink surface layer. A large amount of VOC volatilization will be formed during pre-drying, which will cause great harm to the human body and the environment, and is not conducive to Widespread promotion and use

Abstract

The invention relates to ultraviolet light-heat dual-curing gloss oil for a transfer film, and a preparation method and application thereof. The ultraviolet light-heat dual-curing gloss oil comprises the following components by part by weight: 20 to 70 parts of resin composition, 10 to 50 parts of diluting monomer, 1 to 10 parts of photoinitiator, 0.01 to 5 parts of polymerization inhibitor, 1 to 10 parts of flatting agent, 1 to 10 parts of defoaming agent and 1 to 10 parts of base material wetting agent, wherein the resin composition is a composition of polyurethane acrylic ester resin containing isocyanate group and resin comprising hydroxyl group. The ultraviolet light-heat dual-curing gloss oil is applied to the transfer film industry, so that the problems of low glossiness of printing ink and low resistance and wear resistance of the surface ink layer are effectively solved, the delay curing characteristic of a gloss oil protective layer is improved, the protective layer gloss oil can be extended on the surface of a three-dimensional object completely to form a transfer pattern with good glossiness, the service life is prolonged, and the ultraviolet light-heat dual-curing gloss oil can be stored for 12 months under the conditions of normal temperature and dark place.

Description

technical field [0001] The invention relates to a dual-curing varnish, in particular to an ultraviolet-heat dual-curing varnish for a transfer film and a preparation method and application thereof. Background technique [0002] Because UV varnish does not use organic solvents, has no VOC emissions, high production efficiency, wide range of printing materials, and excellent film-forming performance, it has become one of the best protective films for ink decoration layers and has been widely used in many fields. Applying UV varnish to the protective layer of the transfer film can effectively improve the gloss of the transfer pattern, increase the resistance and abrasion resistance of the transfer film, and increase the aesthetics and use value of the product. This requires that the varnish coating film used to protect the transfer pattern has good plasticity and stability. On the one hand, it must ensure that the transfer pattern can be fully covered and completely cured on th...
