Embodiment 1

[0032] Embodiment 1 of the present invention provides a matte ink suitable for OGS full lamination process. In parts by weight, the raw materials include: 37 parts of thermosetting resin, 10 parts of filler, 15 parts of matting powder, and silicone-free 2 parts of foaming agent, 13 parts of isophorone solvent, 10 parts of ethylene glycol butyl ether, and 12 parts of carbon black.

[0033] The thermosetting resin is a mixture of epoxy resin and acrylic polyurethane resin. The weight ratio of the epoxy resin to the acrylic polyurethane resin is 25:12.

[0034] The epoxy resin was purchased from Nanya NPES-904, and the acrylic polyurethane resin was purchased from allnex UCECOAT2803.

[0035] The filler is talc powder, and the talc powder has an average particle size of 8000 meshes, purchased from Shenzhen Jinhaohui Industrial Development Co., Ltd.

[0036] The matting powder is a hydrophilic matting powder. The specific surface area of ​​the matting powder is 125m 2 / g, the ...

Abstract

The invention relates to matte ink (IPC classification number: C09D11 / 10), in particular to matte ink suitable for an OGS (One Glass Solution) full lamination process and a preparation method of the matte ink. Raw materials at least comprise the following components in parts by weight: 30-45 parts of a resin binder, 8-12 parts of a filler, 12-18 parts of matting powder, 1-2 parts of an organosilicon-free defoaming agent, 10-15 parts of an isophorone solvent, 8-12 parts of ethylene glycol butyl ether and 10-15 parts of carbon black. The dyne value of the matte ink suitable for the OGS full lamination process is larger than 38, the water drop angle can range from 70 degrees to 75 degrees, the fastness of OCA rubberizing is greatly improved, the probability that bubbles are generated during lamination is reduced, meanwhile, the matte ink prepared through the method has good pain and wiping resistance, and even if hydrophilic matte powder is added, the matte ink can still be used for a long time. And the coating also can pass a water boiling resistance test, and has good water resistance.

Description

technical field [0001] The invention relates to a matte ink (IPC classification number: C09D11 / 10), in particular to a matte ink suitable for an OGS full lamination process and a preparation method thereof. Background technique [0002] With the continuous improvement of people's living standards, people's pursuit and requirements for smart devices such as mobile phones are also getting higher and higher. The development of smart devices is inseparable from the development of touch technology. At present, the mainstream touch screen bonding process adopts OGS (integrated capacitive touch screen) full bonding. OGS bonding generally uses OCA glue to bond on a layer of matte black ink. The matte black ink often has higher Dyne value and lower drop angle. However, the increase of the dyne value of the ink is often to improve the surface roughness of the matte powder, but most of the matte powder is a hydrophobic substance, so the higher the dyne value, the higher the water drop...
