Description

Glass product with multicolor function and manufacturing method
Technical Field
The invention relates to the technical field of glass manufacturing, in particular to a glass product with a multicolor function and a manufacturing method thereof.
Background
The atmospheric glass products can present various customized patterns under the irradiation of a light source, and the atmosphere is set aside, so that the atmospheric glass products are widely applied to various vehicles such as automobiles, buildings and the like.
Ambient glazing in the current market is usually produced by printing luminescent ink on glass, synthesizing laminated glass by hot melt film, and then lighting by edge-set light sources. Such products cannot be invisible in pattern after lamp extinction and can only display relatively simple patterns due to the limitation of printing with luminescent ink. In addition, there is a solution in the market that at least three glasses, especially the third glass, are used during the processing, which needs to be removed after the processing is completed, making the processing more complicated.
PVB for door window that market sold at present is in order to consider the exhaust convenience, and the exhaust texture is too dark, reaches more than 20um, and the pattern of making on this can cause the pattern deformation, in the hot melt process, because the glue solution flows, the pattern can the secondary deformation, leads to the pattern to be distorted.

To solve the above-mentioned problems, a first object of the present invention is to provide a glass product with a fantasy color function, comprising:
a glass article having a fantasy color function, comprising a glass article body, the glass article body comprising:
a first glass layer, the first glass layer being a base glass;
the multicolor film is overlapped below the first glass layer and is made of PVB or TPU hot melt adhesive film, and the multicolor film is provided with a first surface and a second surface which are oppositely arranged, wherein the first surface of the multicolor film is provided with a preset pattern;
the second glass layer is made of ultra-white glass, and the first surface of the multicolor film faces to the second glass layer.
As an improvement, an interlayer film is also stacked between the fantasy film and the first glass layer, and the interlayer film is a specially customized PVB film or TPU film with color and heat insulation effects. The special texture compression roller is customized, and hot pressing is carried out during PVB or TPU production, so that the roughness of the surface of the finished PVB or TPU film is less than 5 mu m, and the exhaust is not influenced. After the PVB or TPU is subjected to pattern making, the loss of pattern precision is small, and even the pattern is subjected to hot melting secondary deformation, the pattern is hardly visible to naked eyes.
As a modification, the first glass layer may be white glass or gray glass.
As an improvement, the single side or two sides of the glass product body are also clamped with shading strips, and the light source is also arranged in the single side or two sides of the shading strips.
A second object of the present invention is to provide a method for manufacturing a glass product having a fantasy color function, the method comprising the steps of:

and thirdly, placing the laminated glass product body into the autoclave for reaction to obtain the glass with the multicolor function.
And fourthly, installing side light sources at the two side edges of the multicolor film, and packaging the two side edges of the glass product body by using a shading strip made of opaque materials to obtain the glass product with the multicolor function.
Further, before forming the preset pattern on the first surface of the PVB or TPU hot melt adhesive film, the method further comprises the following steps: and heating and softening the PVB or TPU hot melt adhesive film, wherein the heating temperature is set to be 35-45 degrees.
Further, the step of forming a predetermined pattern on the first side of the PVB or TPU hot melt adhesive film comprises:
when the hot melt adhesive film is PVB hot melt adhesive film, embossing the first surface of the PVB hot melt adhesive film according to preset exhaust, wherein the depth is less than 5 mu m; when the hot melt adhesive film is a TPU hot melt adhesive film, embossing is performed on the first surface of the TPU hot melt adhesive film according to preset exhaust, and the depth is less than 5um.
Further, prior to forming the first glass layer and the second glass layer, glass in the first glass layer and the second glass layer is subjected to preprinting, hot bending forming, and tempering or semi-tempering treatments.
Further, prior to the step of reacting the laminated glass article in the autoclave, further comprising vacuum reacting the laminated glass article;
when the hot melt adhesive film is PVB hot melt adhesive film, the reaction condition is set to minus 0.1 vacuum, the temperature is 100-110 ℃, and the time is 30-60 minutes;

In contrast, the invention adopts the fantasy color film with preset patterns, can display more complex and attractive patterns under the irradiation of the light source, and creates richer atmosphere effects.
2. The technical manufacturing is simplified: current ambient glazing generally requires the use of multiple sheets of glass and involves cumbersome tooling. The manufacturing method of the invention has the advantages that the first glass layer, the interlayer film, the multicolor film and the second glass layer are laminated and then are placed in the autoclave for reaction, so that the manufacturing process is simplified, and the manufacturing cost and time are reduced.
3. Pattern is stealthy after the lamp goes out: after the light of the traditional product is extinguished, the printed pattern can remain visible, and the visual effect is affected. However, the multicolor film adopts a special printing process and special ink, so that the patterns after the lamp is extinguished can be invisible, and the overall beauty of the environment is not affected.
4. An integrated structure: the invention adopts an integrated structure to laminate all elements together without removing any glass layer. Compared with the complex scheme of removing the third glass in the market, the structure of the invention is simpler and durable.
5. Customizable enhancement: the manufacturing method of the present invention allows various customized patterns to be formed on the fantasy film, thereby improving the customizable nature of the product. This provides a larger creative space for applications in different fields of automobiles, buildings, etc.
In summary, the present invention creates a glass article with a higher, richer atmosphere effect by employing novel structures and manufacturing processes. This innovation will be of great interest in various application areas and will have a positive impact on the relevant industry.
