Description
Technical Field
The invention relates to an environment-friendly UV LED curing peelable blue gel, a preparation method and a preparation method thereof, wherein the peelable blue gel is particularly suitable for 395nm UV LED light source irradiation curing.
Background
In recent years, the application range of touch screens has become more and more extensive, and the shadows of touch screens are seen from control/operation systems of factory equipment in industrial applications, electronic inquiry facilities for public information inquiry, cash dispensers for commercial use, mobile phones, PDAs, digital cameras, and the like of consumer electronics. Temporary protection of the touch screen glass by using peelable blue glue is required many times during the manufacturing process of the touch screen. And tearing off the peelable blue glue after the processing is finished so as to protect the product.
The peelable blue gel may be generally classified into a thermosetting type, a solvent volatilizing type, a room temperature curing type, a UV curing type, and the like according to a curing method. The traditional thermosetting peelable blue glue generally contains phthalate plasticizer, and the phthalate plasticizer can generate negative influence on the secretion of human bodies to further influence the reproductive capacity of the human bodies, so that the application of the traditional thermosetting peelable blue glue is limited to a certain extent. In addition, the traditional peelable blue glue has high curing film-forming temperature and long curing time (baking for 20-30 min under the conditions of 120-. The solvent volatile peelable blue glue has the defects of volatile toxic solvent (such as solvent containing triphenyl), insufficient bonding force, good elasticity, poor repairability, low curing speed and the like. The room temperature curing type peelable blue glue generally has the defects of slow curing speed, phthalic ester plasticizer content, poor reworkability and the like.
The UV curing peelable blue glue can radically prevent the use of phthalate substances, and has higher curing speed and higher production efficiency. At present, UV-cured peelable blue glue is mainly a curing system matched with a mercury lamp light source, and with the stricter and stricter global requirements on environmental health, the defects of short service life, heavy pollution, large energy consumption and the like of the mercury lamp light source and the advantages and technical breakthroughs of the UV LED light source, the mercury lamp light source is replaced in many fields. However, the UV LED curing peelable blue glue on the market is relatively few, and has residual glue during peeling, so the solvent is required to wipe the peelable blue glue, which is mainly caused by poor toughness. Therefore, the development of UVLED peelable blue glue which meets the market requirement and has better performance is still urgently needed.
