fourthly, arranging a reflecting layer 3 on the back side surface of the glass substrate 1 in the glaze porcelain ring 2;
and fifthly, arranging a protective layer 5 on the reflecting layer 3.
The glass substrate 1 obtained in the first step may be obtained by cutting ordinary float glass, and the cutting size thereof may be cut according to the size, shape, etc. of the finished mirror to be manufactured, as shown in fig. 3. In addition, in the first step, after cutting and obtaining the corresponding glass substrate 1, the edges of the glass substrate 1 may be also subjected to a chamfering process as appropriate; as shown in fig. 4, wherein the chamfer may be rounded or chamfered.
After the first step is completed, glazing is performed on the back side of the glass substrate 1, and the side glass surface is usually cleaned before glazing to ensure clean surface. The specific glazing process can be carried out by matching with a corresponding screen printing machine, and the shape of the screen is set according to the shape and the like required to be glazed. In the glazing process, the glazing materials with different colors can be selected according to the requirements, such as gold, silver, black, white or purple, and the like, so that the glazed porcelain ring 2 finally formed after firing has corresponding colors and can play a role in beautifying the mirror. In the glazing process, other beautifying patterns can be formed by glazing according to the requirements besides the corresponding glaze material ring shape of the corresponding glaze porcelain ring 2, so as to play a role in beautifying the mirror. And a different shape pattern may also be used during the glazing of the circles of glazing material, as shown with reference to figures 11 and 12.
In addition, the thickness of the glazed material is usually set to be 35-40 μm, and the thickness of the glazed porcelain ring 2 formed after firing is ensured to be approximately consistent with the thickness of the reflective layer 3 arranged later, so that the glazed porcelain ring 2 can be smoothly covered on the reflective layer 3 and the glazed porcelain ring 2 when the protective layer 5 is arranged later, and the conditions of steps, sections and the like are avoided.
In order to ensure the sealing protection of the edges of the reflective layer 3, a closed ring of glazing material needs to be formed after glazing; meanwhile, the glaze material ring should be as close to the peripheral edge of the glass substrate 1 as possible, for example, the edge of the glaze material ring is level with the edge of the glass substrate 1; the glazed porcelain ring 2 formed by firing can improve the strength and the abrasion resistance of the periphery edge of the mirror.
In addition, in the third step, in the process of tempering the glazed glass substrate 1, in order to simultaneously realize firing of the enamel ring to form the enamel ring 2, a high-temperature firing process is employed for the tempering process. In particular, the tempering treatment process of high-temperature firing is usually performed by a glass tempering furnace, and the firing temperature, the firing time and the like of the tempering treatment process are related to parameters such as thickness and the like of glass, and are usually set at 600-700 ℃, and the tempering treatment process can be specific according to practical situations.
The glass substrate 1 after the tempering treatment has the property of tempered glass, has high strength, is not easy to break and is not easy to form sharp edges after breaking, and the use safety of the glass substrate can be improved. Meanwhile, the corresponding glazed porcelain ring 2 also has stronger strength, and can play a role in protecting the whole edge of the mirror. The structure after tempering treatment is shown in figure 5.
In addition, in the third step, the glazing material ring can be subjected to low-temperature curing treatment firstly, and then the glazed glass substrate 1 can be subjected to tempering treatment; the low-temperature curing treatment can be used for primary curing of the glaze material ring, so that the condition that the glaze material ring is deformed in the subsequent treatment process is prevented, and better conditions are provided for the subsequent treatment process. Wherein, the low-temperature curing treatment adopts an oven, and the baking temperature of the oven is set to be 230-240 ℃. In addition, the "low temperature" and the "high temperature" described in the above-described low temperature curing treatment and high temperature firing process are in a relative size relationship.
More specifically, the invention further comprises the following treatment process between the third step and the fourth step: the protective film 4 is provided on both the peripheral edge of the glass substrate 1 and the peripheral edge of the glaze material ring and in a partial area on the front side thereof near the peripheral edge. The protective film 4 is provided to protect the edge portions of the enamel ring 2 and the glass substrate 1, and if necessary, the entire front side surface of the glass substrate 1 or a partial region of the front side surface near the peripheral edge can be covered and protected; so as to avoid polluting the front side surface of the glass and the edges of the glass substrate 1 and the enamel ring 2 in the subsequent processing process; the covering region in which the protective film 4 is specifically provided can be seen with reference to fig. 6. Specifically, the protective film 4 may be a PVC film or a PE film; and when the protective film 4 is paved, manual paving or mechanical automatic paving can be adopted, and meanwhile, redundant parts at the edge of the protective film 4 can be cut off by utilizing tools such as a blade and the like according to paving conditions after paving so as to ensure effective setting of the subsequent reflective layer 3 and the protective layer 5.

Without loss of generality, in the fourth step, the reflective layer 3 may be formed by an electroplating process, and in the fifth step, the protective layer 5 may be formed by a paint spraying process; the electroplating process and the paint spraying process are both the prior art, and are not described herein. Specific construction flows are shown with reference to fig. 7 to 9. After all the steps are completed, the finished mirror can be obtained only by dismantling the corresponding protective film 4.
More specifically, in order to ensure that the outer peripheral edge of the light reflecting layer 3 is effectively sealed and isolated by the protective layer 5 and the enamel ring 2 after the protective layer 5 is covered, so as to prevent the edge of the light reflecting layer 3 from being oxidized to cause black or red edges, the protective layer 5 is arranged to cover the light reflecting layer 3 and the enamel ring 2 at the same time, as shown in fig. 2.
