Example 1
A method for preparing a vehicle window glass, as shown in fig. 1, comprises the following steps:
step 100: as shown in fig. 6, a substrate glass 1 is provided, and a color-changing region 11 and a non-color-changing region 12 are formed on one surface of the substrate glass 1, and the thickness of the non-color-changing region 12 is greater than the thickness of the color-changing region 11.
In this step 100, the substrate glass 1 has two surfaces disposed opposite to each other, one surface is a concave-convex surface, the other surface is a plane, the concave area on the concave-convex surface forms the color-changing area 11, and the convex area forms the color-changing area 11.
In this embodiment, the thickness of the color-changing region 11 of the substrate glass 1 is about 3.0mm, and the thickness of the non-color-changing region 12 of the substrate glass 1 is about 5.3 mm.
The substrate glass 1 may be formed by locally thinning one surface of a glass substrate with a thickness equal to 5.3mm to form the color-changing region 11 and the non-color-changing region 12 with different thicknesses, and the thinning mode may be etching method or CNC method, which has low cost and fast etching speed, but low etching precision, and is easy to oversetch to cause the color-changing region 11 to be too thin, or less to cause the color-changing region 11 to be too thick, and the CNC method has high polishing precision, but long time consumption, and the CNC grinding head is easy to wear and has high cost.
Preferably, in this embodiment, a process of combining an etching method and a CNC method is used for the local thinning of the substrate glass 1, as shown in fig. 2, and the specific steps are as follows:
step 101: providing a glass substrate with uniform thickness.
In this step 101, the glass substrate is preferably, but not limited to, tempered glass.
Step 102: an etching resist film is formed on a surface of the glass substrate.
In step 102, the anti-etching film mainly protects a surface of the glass substrate from being corroded by the etching solution in a subsequent process.
Step 103: a photoresist is formed on the other surface of the glass substrate.
Step 104: and exposing and developing the photoresist to form a hollowed-out area and a shielding area, wherein the hollowed-out area corresponds to the color-changing area 11 and has a size slightly smaller than that of the color-changing area 11, and the shielding area corresponds to the non-color-changing area 12 and has a size slightly larger than that of the non-color-changing area 12.
Step 105: and etching the glass substrate exposed from the hollowed-out area of the photoresist by adopting etching liquid to form a groove structure.
In this step 105, the depth and the size of the groove structure are smaller than those of the color-changing area 11, and the surface of the groove structure is also formed with a thickness of easily-grinded area by the action of the etching solution, and the easily-grinded area becomes loose in structure due to the corrosion of the etching solution, and is more fragile and easy to be grinded by the CNC grinding head.
Step 107: and stripping the residual photoresist on the glass substrate.
In this step 107, after the remaining photoresist glass, the edge regions of the trench structures are exposed.
The etching resist film can be peeled off together with the remaining photoresist, or can be peeled off at any subsequent time (before the explosion resist film 5 is attached).
Step 106: and grinding the groove structure of the glass substrate by adopting a CNC grinding head to form the color-changing area 11.
In this step 106, the edge area and the bottom area of the groove structure are polished by the CNC grinding head, and at least the easily-polished area of the groove structure is polished to enlarge the depth and size of the groove structure to the depth and size of the color-changing area 11, so that the color-changing area 11 is formed, and the rest of the glass substrate naturally forms the non-color-changing area 12.
Step 200: and attaching a piece of photochromic glass 2 to the color-changing area 11 of the substrate glass 1 through the OCA glue 3, wherein the total thickness of the photochromic glass 2, the OCA glue 3 and the color-changing area 11 of the substrate glass 1 is equal to the thickness of the non-color-changing area 12 of the substrate glass 1.
In this step 200, the photochromic glass 2 is preferably, but not limited to, a halogen glass, in which a halogen compound, such as silver halide, is mixed, when the external light is strong light, the halogen compound in the photochromic glass 2 is instantaneously decomposed into halogen and metal ions, and after the halogen content in the photochromic glass 2 is increased, the color is darkened to reduce the external light from entering the cab, so as to avoid the eyes of the driver from being stimulated by the external light, when the external light is weak light, the halogen and metal ions in the photochromic glass 2 are recombined into the halogen compound, and after the halogen content in the photochromic glass 2 is reduced, the color is lightened and becomes transparent, so that the external light enters the cab to increase the brightness of the cab.
In this example, the thickness of the photochromic glass was about 2.0mm, and the thickness of the OCA paste was about 0.3 mm.
Specifically, as shown in fig. 3, in step 200, the step of attaching the photochromic glass 2 to the color-changing region 11 of the substrate glass 1 through the OCA paste 3 is as follows:
step 201: and (3) aligning and attaching the OCA glue 3 on the photochromic glass 2 under the monitoring of a CCD.
