Embodiment 1

[0019] Formula: CN965NS (aliphatic urethane acrylate oligomer) 20 parts (parts by weight, the same below); CN9001NS (aliphatic urethane acrylate oligomer) 20 parts; SR285 (tetrahydrofuran acrylate active monomer) 30 parts; SR238NS (1,6-hexanediol diacrylate active monomer) 16 parts; TPOUV photoinitiator 3 parts; 1173UV photoinitiator 2 parts; fumed silica anti-settling agent 1 part; , 8 parts of alkali-free ultrafine glass fiber.

[0020] Before use, the superfine glass fiber is surface-treated. The treatment process is: dry the superfine glass fiber at 120°C for 2 hours, and then add the superfine glass fiber to the high-speed stirrer. Drop 2% ethanol solution containing silane coupling agent KH550 onto the glass fiber, stir at high speed for 5 minutes, then put it in an oven at 120°C and bake for 2 hours, that is, the treated ultrafine glass fiber. The weight ratio of ultrafine glass fiber and KH550 used is 100:1.

[0021] According to the previous recipe, the components w...

Embodiment 2

[0023] In the above-mentioned embodiment 1, the ultra-fine glass fiber is replaced with a precursor with a diameter of 2 μm and a length of 16 μm, and 12 parts of medium-alkali type ultra-fine glass fiber. Add: 2% cyclohexanone solvent, 1% calcium silicate inert filler, 0.5% organic silicon defoamer, so as to facilitate the mixing reaction. Then it is configured as a light-cured transfer printing material, which is transferred to a polycarbonate film with numbers, and can be made into a thin digital keypad.

Abstract

The invention relates to a photocuring transfer printing material that can be printed on surfaces of transparent or semitransparent glass, plastic or rubber. The material comprises of the following components: 25-45% of oligomer, 30-50% of activated monomer, 2-8% of UV(ultraviolet) photoinitiator, 1-20% of superfine glass fiber, 0-5% of inert filler and 0-5% of organic solvent, wherein the oligomer is one or more of polyurethane acrylate, aliphatic polyurethane methacrylate, polyester acrylate and epoxy acrylate; the curing of the photocuring transfer printing material is caused by UV radiation; and the glass fiber is dipped with a silane coupling agent. The photocuring transfer printing material is small in curing shrinkage rate, high in wearing resistance and convenient to use, and has a strong adhesive force with surfaces of transfer printing substrates; and a construction process and a curing process of the material are basically the same with those of the traditional photocuring material.

Description

technical field [0001] The invention relates to a light curing transfer printing material which can be used on the surface of transparent or translucent glass, plastic or rubber. Background technique [0002] Photocuring (such as ultraviolet light or UV light curing) polymer materials has the advantages of low pollution, low energy consumption, and environmental friendliness. This material can be used as paint, ink or transfer adhesive material. The so-called transfer adhesive material means that this material can be solidified and formed by attaching to plastic sheets, flat glass and other substrates with a certain three-dimensional pattern. In the actual construction process, the oligomers and active monomers in this adhesive material are polymerized into a network-like solid polymer structure under the combined action of photoinitiators and irradiated light, which can bond other materials in contact with it. materials, and form three-dimensional patterns on the surface ...
