Problems solved by technology

[0003] Traditional coatings are volatile and slow in curing, which is not conducive to environmental protection. Therefore, UV coatings are the main substitute for traditional coatings
However, at present, baking-type glass protective inks and UV-type protective inks are mainly used to protect the glass screen of mobile phones. Finally, it must be baked at 150 degrees for 15 minutes. After drying and cooling, the other side can be printed and dried again, which is inefficient, wastes energy, and pollutes the environment.
Existing UV coatings need to add adhesives on the construction site to increase their adhesion; and when the glass is cut or punched, and the alkaline water ultrasonically fades the film, the UV film will fall off in pieces, which will cause difficulties in the subsequent cleaning of the glass screen. not ideal

Abstract

The invention discloses a UV coating for cutting machining for 3C product glass screens and being soluble in alkali and a preparation method of the UV coating. Ink is prepared by the following components in percentage by weight: 25-40% of bifunctional polyester acrylates, 25-40% of styrene maleic anhydride copolymer resin, 2-5% of dipentaerythritol hexaacrylate, 2-5% of a trifunctional phosphate ester adhesive agent, 3-5% of an acrylic ester coupling agent, 10-20% of talcum powder, 1-2% of polytetrafluoroethylene wax powder, 1-2% of phthalocyanine blue, 4-6% of 184, 3-5% of TPO and 0.5-2% of an addition agent. When the prepared UV ink is applied to the 3C product glass screens, the adhesive agent does not need to be added during site operation, and when films are taken off, the films are dissolved into particulate precipitation to the bottom of an alkali-solution tank, the subsequent cleaning for glass machining is convenient and quick, and the condition that the taken films are adhered to glass due to large sizes, so that cleaning is troublesome can be avoided.

Description

technical field [0001] The invention relates to the field of inks, in particular, the invention relates to an alkali-soluble UV screen printing ink for cutting and processing glass screens of 3C products. Background technique [0002] UV curing coating is a new type of coating popular in Europe, America, Japan and other places at the end of the 20th century. It was first applied to the surface coating treatment of furniture, floors, mobile phones, and walkman casings. UV curing coatings have developed rapidly due to their advantages of no volatile organic compounds (VOC), less environmental pollution, fast curing speed, energy saving, good performance of cured products, and suitable for high-speed automatic production. Its application fields are now further expanded to Cosmetic containers, household appliances such as televisions and computers, and other fields such as motorcycles and glazing. [0003] Traditional coatings are volatile and slow curing, which is not conduciv...
