Description
Technical Field
The invention relates to the technical field of laminated glass, in particular to laminated glass with clear patterns.
Background
With the development of laminated glass technology and the increasing environmental requirements of people for work and living places, more and more varied laminated glass appears, wherein patterns are often presented in the laminated glass. However, in many cases, a pattern is printed on a special plastic film, a metal or non-metal sheet, a decorative paper, or the like, and then the printed pattern is attached to an organic adhesive material intermediate film or a glass plate.
Chinese patent CN200520041519.0 discloses a laminated glass for clamping decorative materials, which has the following structure: the glass plate comprises a glass plate, an organic adhesive material intermediate film, a metal or non-metal decorative material, an organic adhesive material intermediate film and a glass plate, wherein the organic adhesive material intermediate film is PVB, EVA, SGP or the like; the laminated glass with the structure not only has complex manufacturing process, but also has obvious defects that: with the time, plastic films, metallic or non-metallic sheets, decorative papers, and the like are easily aged, so that the aesthetic feeling is remarkably reduced, and even the patterns thereon are deformed and fall off.
In addition, some improved technologies for the above patents, such as chinese patent No. cn201310043876.X, print a pattern directly on the transparent intermediate layer or the milky white intermediate layer, and penetrate into the transparent intermediate layer or the milky white intermediate layer, so that the transparent intermediate layer or the milky white intermediate layer is durable and not easy to age; the problem with this approach is that the interlayer PVB or SGP is a thermoplastic material that can distort or crack the design when subjected to heat and pressure during the manufacture of the laminated glass, which can affect the aesthetics of the glass.
The EVA resin is an ethylene-vinyl acetate copolymer, and is widely used for halogen-free flame-retardant cable outer sheaths, foamed shoe soles, glass interlayers, photovoltaic adhesive films and the like. The polymer can be crosslinked by using peroxide thermally, or can be crosslinked by adding a proper photoinitiator and an auxiliary crosslinking agent to carry out ultraviolet curing or by using high-energy radiation irradiation. When the EVA resin is crosslinked, it loses most of its plasticity and does not flow easily in a hot environment.
Disclosure of Invention
The present invention has been made to overcome the above-mentioned drawbacks of the prior art, and an object of the present invention is to provide a laminated glass exhibiting a high definition pattern, which has an intermediate layer having a suitable degree of crosslinking before use to improve the dimensional stability and heat resistance of a film, and which does not undergo deformation or cracking due to stretching of a film during use, thereby obtaining a laminated glass exhibiting a high definition pattern.
In order to achieve the above object, the present invention provides a laminated glass exhibiting a clear pattern, comprising: the pattern structure comprises a preset pattern and a pre-crosslinked and cured first adhesive film, wherein the preset pattern is arranged on the surface of the first adhesive film so as to present a clear pattern.

A layer of pre-crosslinking film printed with patterns can be arranged between the double-layer glass provided by the invention, and also a layer of pre-crosslinking film and a layer of adhesive film printed with patterns (at least one of the two adhesive films is transparent) can be arranged between the double-layer glass, or other compositions can be arranged between the two layers of glass. The pattern side of the adhesive film printed with the pattern is tightly attached to the pre-crosslinking film, namely the pattern is not necessarily printed on the pre-crosslinking film, but the pattern is necessarily tightly attached to the pre-crosslinking film. The film layer which has been pre-crosslinked is not deformed after heating, and the pattern printed on it or the pattern applied to it is not deformed during the glass processing.
Preferably, the adhesive film is a transparent, translucent or opaque adhesive film. The opaque adhesive film is preferably a white adhesive film.
Preferably, the pre-crosslinking curing is ultraviolet crosslinking curing or radiation crosslinking curing.
Preferably, the irradiation energy source for irradiation crosslinking curing is one of beta rays, gamma rays, X rays, alpha rays or neutron rays; the ultraviolet crosslinking curing is to use light with the wavelength of 240 to 410 nanometers to trigger an ultraviolet curing crosslinking agent to cause the crosslinking of the EVA resin.
Preferably, the pre-crosslinking degree of the pre-crosslinking curing is 0.5-85%.
Preferably, the adhesive film is an EVA adhesive film, and the content of VA in the EVA resin forming the EVA adhesive film is between 18% and 35%.
