Problems solved by technology

[0007] Some of the above methods combined with lighting effects can produce a variety of signboards or decorative items, but the above methods have certain shortcomings. The two methods 1 and 2 produce flat effects, and the visual impact is not strong. 3 4. Basically, the two methods can only use monochromatic substrates, and the color effect is not good. The fourth method is difficult to make more complicated and fine items

specific Embodiment

[0028] 1. Preparation of UV curable decorative adhesive: see Table 1 for the formula

[0029] Table 1.

[0030]

[0031] 2. The production process of UV curing decorative glue:

[0032] Prepare each component by the prescription of above-mentioned embodiment 1-5. First mix UV monomers in proportion, add photoinitiator, stir to dissolve, then add polyester acrylate, stir evenly, then add additives, add fumed silica under high-speed stirring, stir for about 1 hour, and then proportionally Add coloring material, stir for 30 minutes, and obtain UV curable decorative glue after filtering.

[0033] The products prepared according to the formula of Examples 1-5 all meet the requirements for use, that is, the viscosity is 120,000-200,000 cps / 25°C, the surface tension is 28-35 dyne / cm, and the curing energy is greater than 300mJ / cm 2 .

[0034]When in use, patterns and characters can be formed by extrusion dispensers. The extrusion dispensing machine is controlled by computer, ...

Abstract

The invention discloses a novel UV (ultraviolet)-curable decoration adhesive. The formula of the decoration adhesive comprises the following components in percentage by mass: 35-60% of UV oligomer, 30-55% of UV monomer, 4-10% of photo initiator, 1-5% of rheology control additive, 0.1-0.5% of defoaming agent, 0.1-0.5% of substrate wetting agent and 0-5% of pigment. The UV-curable decoration adhesive can be coated on a substrate by an extrusion dispenser to form three-dimensional patterns and words with different heights and rich colors or profiles of patterns and words; and different pigments or spray-printing UV ink can be added, so that the patterns have various colors and special effects, such as metal texture, pearl light, fluorescence, color change and the like, thus signboards or decorative articles are move beautiful.

Description

technical field [0001] The invention relates to the field of curing glue, in particular to a UV curing decorative glue. Background technique [0002] Nowadays, there are more and more types of advertising signs and decorative items, and the production methods and effects are also various. The main ones are as follows: [0003] 1. Use some flexible media to hollow out patterns or characters and paste them on another substrate; [0004] 2. Use the method of inkjet printing to print patterns or text directly on the substrate, such as printing with UV ink, printing with eco-solvent ink, etc.; [0005] 3. Use the engraving method to engrave patterns or characters on the substrate; [0006] 4. Use the plastic method to make three-dimensional patterns or characters; [0007] Some of the above methods combined with lighting effects can produce a variety of signboards or decorative items, but the above methods have certain shortcomings. The two methods 1 and 2 produce flat effects...
