Problems solved by technology

However, cutting the strengthened glass is very troublesome, with high cost and low yield, and some capillary cracks are formed on the edge of the glass, resulting in a decrease in glass strength. Even after secondary strengthening with strong acids such as HF, the glass strength is still insufficient.
[0003] The three-strong adhesive technology on the market is not yet mature, mainly colorless or milky white, and there are problems such as difficulty in tearing the film after sizing and curing, insufficient colloid bonding strength, easy peeling during CNC, and difficult rework, etc., which have great impact on the improvement of glass strength No help or very limited, still needs improvement in terms of performance stability and operability

Abstract

The invention discloses a glass reinforced UV adhesive and a preparation method thereof. The glass reinforced UV adhesive is prepared from the following raw materials in percentage by weight: 30-50% of an oligomer, 40-60% of an active monomer, 3-10% of a photoinitiator and 1-10% of an auxiliary, wherein the oligomer is one or more of polyurethane acrylate, polybutadiene acrylate, epoxy acrylate, pure acrylic resin and polyesteracrylate; the active monomer is one or more of monofunctional, bifunctional and multifunctional acrylates; the photoinitiator is one or more of free radical photoinitiators; the auxiliary is one or more of an adhesion promoter, a defoamer, a flatting agent, a wetting agent and an antioxidant. According to the glass reinforced UV adhesive disclosed by the invention, the strength of the glass is enhanced, and the glass can undergo severe process conditions in the preparation process, can be blended into different colors and is stable in performance.

Description

technical field [0001] The invention relates to the field of chemical materials, in particular to a glass-reinforced UV glue and a preparation method thereof. Background technique [0002] At present, electronic products are developing towards thinner and lighter, emphasizing portability and good visual effects. Therefore, the thinning of display screens or touch screens, which are important components, has become one of the inevitable trends. However, when the glass involved in the display or touch screen is thinned, its strength will decrease to a large extent, so it usually needs to be strengthened first (the obtained tempered glass). Strengthen, and then do coating, etching, cutting and other treatments. However, the cutting of the strengthened glass is very troublesome, with high cost and low yield, and some capillary cracks are formed on the edge of the glass, resulting in a decrease in glass strength. Even after secondary strengthening with strong acids such as HF, t...
