The process flow of the invention comprises the following steps:
step 1): preparing the liquid semi-cured adhesive into a semi-cured adhesive by a UV curing method, a temperature curing method or a moisture curing method;
step 2): coating the semi-cured adhesive on the substrate layer
Step 3): adhering a glue layer and a silica gel layer;

As can be seen from the above process flow of the present invention, the process undergoes two curing steps: the first curing is a semi-curing process from glue generation to glue film, and applicable curing methods include a thermal curing method, a UV curing method, a moisture curing method, and the like. The second curing is from a semi-solid glue to a hard body, and usable curing methods include a thermal curing method, a UV curing method, a moisture curing method, and the like.
Through twice curing process treatment, the glue is firstly made into a semi-cured jelly shape, then the glass film and the mobile phone screen are clamped tightly and then the section difference is filled again, and then the UV curing is carried out again, so that the glue layer does not rebound and deform, the full lamination is realized comprehensively, and compared with a flexible film, the flexible film has the advantage of difficulty in leaving marks.
UV curing is ultraviolet curing, which is an acronym for ultraviolet light, and curing refers to the process by which a substance is converted from a low molecule to a high molecule. UV curing generally refers to the curing conditions or requirements of coatings (paints), inks, adhesives (glues) or other potting, sealants, etc. that require curing with ultraviolet light, as distinguished from thermal curing, curing with crosslinking agents (curing agents), natural curing, etc.
The resin systems employed by the UV curing technique, which involve a basic oligomer, essentially a low molecular weight (about 2500) prepolymer, commonly used urethane acrylates (urethane acrylates), epoxy acrylates, polyester acrylates or polyether acrylates, vinyl ethers, acrylate-free oligomers and the like, are also being increasingly employed. The oligomer has high viscosity, and in order to facilitate construction and increase the crosslinking and curing speed, a monomer is required to be added as a reactive diluent to adjust the rheological property of the resin. The structure of the reactive diluent has an important influence on the properties of the final coating film, such as flowability, slip, wettability, swellability, shrinkage, adhesion and migration within the coating film. The reactive diluent may be monofunctional or polyfunctional, the latter being preferred because it provides an increased degree of crosslinking upon curing. The performance requirements of reactive diluents are the dilution power, solubility, odor, ability to reduce the viscosity of the medium, volatility, functionality, surface tension, shrinkage during polymerization, glass transition temperature (Tg) of the homopolymer, influence on the overall curing speed and toxicity.
The present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof, and it is therefore intended that all such changes and modifications as fall within the true spirit and scope of the invention be considered as within the following claims.
