Abstract

The embodiment of the invention provides a staged photocureable coating, a thermal transfer film, a decorative device and a preparation method, and relates to the technical field of transfer materials. The staged photocureable coating is prepared from the following components in parts by weight: 40 to 70 parts of macromolecular compound, 30 to 60 parts of acrylic resin, 5 to 10 parts of monofunctional monomer, 5 to 10 parts of polyfunctional monomer and 1 to 10 parts of photoinitiator. According to the heat transfer printing film, a staged photocureable coating coats a release layer, and a semi-cured functional layer is formed through UV curing. A heat transfer method comprises the steps that the surface, provided with a bonding layer, of the heat transfer film is attached to a device, certain temperature and pressure are applied, so that the bonding layer is attached to the device, and transfer printing is completed; and a transparent PE protection layer covers the device after transfer printing, and then UV curing is carried out to completely cure the semi-cured functional layer to form the functional layer. The coating layer formed by the coating can be cured by stages, has high stretchability and good wear resistance, and can meet the requirements of various transfer printing devices.

Description

technical field [0001] The application relates to the technical field of transfer printing materials, in particular, to a step-by-step photocuring coating, thermal transfer film, decorative device and preparation method. Background technique [0002] Thermal transfer film is a kind of graphic information printed or coated on the carrier film, and then through professional equipment under a certain temperature and pressure, the graphic information is peeled off from the carrier film through the bonding effect of hot melt. , transferred to the corresponding device, so that it has a certain function and a certain decorative effect. With the development of technology and the advancement of technology, the competition in the consumer electronics and automotive markets has entered a fierce stage. Consumers have put forward higher requirements for the performance of related products, not only for aesthetics, but also for durability. [0003] The traditional thermal transfer film h...
