Problems solved by technology

[0003] At present, the existing supporting frame adhesive products in the market are milky white or black after curing, which does not meet the need for transparency; the curing method is generally thermal curing or UV heating curing, which has high energy consumption and low production efficiency; the glass transition temperature is relatively low. High, the frame glue becomes hard and brittle after curing, and the flexibility is very poor
The ordinary UV adhesives in the market generally have low viscosity, poor straight line drawing and poor shape retention during coating, which makes the edges after coating uneven and fail to reach the design height; in addition, the bistable liquid crystal dimming layer is usually The refractive index of light is generally between 1.50-1.56, while most of the existing transparent UV adhesives in the market are between 1.43-1.50, which does not match the refractive index of the light-adjusting layer, which seriously affects the visual effect of the transparent state

Embodiment Construction

[0021] In the following description, for purposes of explanation and to have a comprehensive understanding of the present invention, numerous specific details are set forth, however, it will be obvious to those skilled in the art that the present invention can be practiced without these specific details. . The illustrative example embodiments of the present invention have been set forth for purposes of illustration only, and are not intended to be limiting of the present invention. Therefore, the protection scope of the present invention is not limited by the specific embodiments, but only by the scope of the appended claims.

[0022] As stated in the prior art, currently bistable dimming products are mainly used in rigid glass substrates, which cannot be cut arbitrarily, and cannot be produced and transported roll-to-roll. To realize the thin film of bistable dimming products, it is necessary to provide a The flexible support structure, at the same time, this flexible suppor...

Abstract

The invention discloses an ultraviolet-curing structural adhesive composition. The ultraviolet-curing structural adhesive composition comprises the following components in percentage by mass: 30%-80% of (meth)acrylate oligomer, 5%-40% of a (meth)acrylate monomer, 2%-10% of a thiol monomer, 1%-10% of a photoinitiator and 1%-20% of an adhesion promoter. The ultraviolet-curing structural adhesive composition has the advantages of transparency, high viscosity and excellent bonding force with an ITO base material, can be used for bonding of a display device and a flexible device, and realizes film formation of a dimming product.

Description

technical field [0001] The invention relates to the technical field of structural adhesives, in particular to an ultraviolet light curing structural adhesive composition and its application. Background technique [0002] With the rapid development of the display industry, flexible display products have great market advantages. In the field of electronic dimming, thin-film dimming products have become the mainstream of the development of the dimming industry because of their low cost, arbitrary cutting, and roll-to-roll convenience for production and transportation. PDLC is currently the only mass-produced thin-film dimming product. It is foggy when the power is off, and transparent when it is powered on. The transparent state requires voltage maintenance. Since most of the transparent states are used in daily use, energy consumption is serious, and the viewing angle of PDLC is relatively large. Large, affecting the visual effect, has its development limitations; the bistabl...
