Problems solved by technology

[0003] In recent years, the development of 3C products such as mobile phones, computers, TVs, and MP3 / MP4 tends to be touch-operated. At present, glass screens are used for touch screens. On the one hand, due to the high density of glass, the entire equipment is heavy and difficult to move; On the one hand, due to the poor impact resistance of the glass and its fragility, the screen is easy to crack during use

Abstract

The invention discloses a high impact resistance ultraviolet curing coating combination and a use method thereof, and the high impact resistance ultraviolet curing coating combination comprises the following components: by weight, 30 ~ 45 parts of acrylic resin, 45 ~ 65 parts of a monomer, 4 ~ 6 parts of a light initiator, 100 ~ 250 parts of a solvent and 0.05 ~ 0.5 part of a levelling agent. The acrylic resin is one or a plurality of resin from low-functionality-degree aliphatic polyurethane acrylate resin, aliphatic polyester acrylate resin, aliphatic polyurethane methacrylate resin and aliphatic polyester methacrylate resin. Compared with the prior art, the impact resistance of the combination is increased to 11.3 g * 100CM compared with that of the glass, and compared with the glass, the finished product rate in subsequent cutting and carving processes is increased, and the cost is reduced.

Description

technical field [0001] The invention belongs to the field of ultraviolet light-curable coatings, and in particular relates to a high-impact-resistant ultraviolet light-curable coating composition and a use method thereof. Background technique [0002] Ultraviolet curing coatings (UV coatings) have the advantages of high efficiency, energy saving, wide applicability, and room temperature curing, and have been widely used in electronics, communications, chemicals, machinery, furniture, inks and other fields. According to the different substrates used, UV coatings can be simply divided into: UV coatings for plastic substrates, UV coatings for metal materials, UV coatings for wood, UV coatings for inorganic materials, UV coatings for paper, etc. [0003] In recent years, the development of 3C products such as mobile phones, computers, TVs, and MP3 / MP4 tends to be more touch-based. At present, touch screens use glass screens. On the one hand, due to the high density of glass, the...
