preparation example Construction

[0045] In another preferred embodiment of the present application, a method for preparing a soft mold is provided, that is, preferably, the above-mentioned step S1 includes: setting a mixture formed of a UV-curable adhesive composition on the metal mold 10; setting a soft substrate on the mixture , and the soft substrate is rolled; the mixture after the roll is solidified to obtain a cured layer; and the metal mold is removed, and the cured layer is subjected to UV curing to obtain a soft mold 20 (reference figure 2 ).

[0046] By curing first and then curing, the hardness and surface dyne value of the soft template can be flexibly controlled. For example, in order to control the surface dyne value 2 . In addition, the above-mentioned surface dyne value is also conducive to improving the stain resistance of the soft mold. On the one hand, after strong UV curing, the soft film glue can fully react, so that it can reach a higher hardness, and the surface structure is not easil...

Abstract

The invention provides a UV (Ultraviolet) cured glue composition, a soft mold and a transfer printing method. In parts by weight, the UV cured glue composition is prepared from 15 to 35 parts of polyurethane acrylate oligomer, 5 to 20 parts of silicon modified resin, 30 to 50 parts of first monomer and 2 to 8 parts of first photoinitiator. The UV cured glue composition contains the polyurethane acrylate oligomer and the silicon modified resin with the use levels, and therefore, is cured under UV irradiation, so that the surface dyne value of the UV cured glue composition is enabled to be controllable; when the UV cured glue composition is used as the soft mold, a difference between the surface dyne value of the UV cured glue composition and the surface dyne value of a decorative film formed through solidification is controlled to be larger; thus, the purpose that the UV cured glue composition and the decorative film are easily separated can be realized; further, the problem that the soft mold is difficultly demolded is solved.

Description

technical field [0001] The invention relates to the field of transfer printing, in particular to a UV curable adhesive composition, a soft mold and a transfer printing method. Background technique [0002] With the rapid development of social economy, people's living standards continue to improve, so the demand for decorations is also increasing, and the requirements are getting higher and higher. Among the decorative glass, the main methods of making pattern structure on the glass are mechanical engraving and thermal transfer printing. The method of mechanical engraving is labor-intensive and time-consuming, and has high requirements for the glass itself; On the glass, the process is simplified, but the cost is high, it is easily affected by the environment or it is easy to fall off during cleaning, and the service life is short. [0003] The patent application with the application number 201510443701.7 discloses a glass transfer process, including: coating a layer of UV g...
