Description

Mirror and its processing method

The present invention relates to a method of processing a mirror and a mirror processed by the method.

In everyday life, the mirror material is widely used. The mirror typically comprises glass and a reflective layer overlying a surface of the glass. The reflective layer is usually a metal material such as aluminum, silver or copper. In order to avoid oxidation and rust of the metal material of the reflective layer, a layer of back paint is applied on the reflective layer to prevent the reflective layer from directly contacting the air. Mirrors (such as mirrors) are often used in humid environments, often in contact with substances such as water, oxygen or detergents. Although coated with a backing for protection, the reflective layer is still contaminated by the exposed edges. Corrosion causes blackening of oxidation.

In view of the above, it is necessary to provide a mirror with low safety hazard and a protective coating that is not easily contaminated and corroded.

In addition, it is also necessary to provide a processing method for preparing the above mirror.

A mirror comprising a lens, the lens comprising a glass substrate, a reflective layer formed on a surface of the glass substrate, and a backing layer formed on the surface of the reflective layer away from the glass substrate, the mirror further comprising a first film layer and a second film layer formed by different materials, the first film layer covering at least a periphery of the lens, the second film layer being formed on a surface of the back paint layer away from the reflective layer and with the back paint The layers correspond, and the first film layer cooperates with the second film layer to cover the periphery of the lens and the back paint layer.

A method of preparing a mirror as described above, comprising the steps of: providing a lens comprising a glass substrate, a reflective layer formed on a surface of the glass substrate, and a surface formed on the reflective layer away from the glass substrate a first backing layer; a first film layer material and a second film layer material different from the material of the first film layer material; the first film layer material is coated on at least the periphery of the lens, and is away from the backing layer Forming the second film layer on the surface of the reflective layer and corresponding to the position of the back paint layer to form the second film layer, and the first film layer material cooperates with the second film layer material to coat the lens a peripheral edge and the backing layer; curing the first film layer material to form a first film layer on the lens.

In the present invention, the method is processed into a mirror, and the first film layer and the second film layer cooperate to cover the periphery of the lens and the back paint layer thereof, thereby facilitating contact with the back paint layer such as water or oxygen. The reflective layer causes the back paint layer and the reflective layer to be contaminated and rusted. In addition, the first film layer and the second film layer are combined with the back paint layer, and the fragments adhere to the first film layer and the second film layer when the lens is broken, thereby reducing the safety hazard caused by the debris of the lens. .

The lens 10 includes a glass substrate 11 and a forming A reflective layer 13 on one surface of the glass substrate 11 and a back paint layer 15 formed on the surface of the reflective layer 13 away from the glass substrate 11. The glass substrate 11 is chamfered at the junction of the surface on which the reflective layer 13 is formed and the four side faces to prevent the edge of the glass substrate 11 from being easily damaged when it comes into contact with other objects. The material of the reflective layer 13 may be a metal such as silver or aluminum. The backing layer 15 is made of a wear-resistant varnish such as a PU varnish or a UV varnish.

The first film layer 30 covers at least the periphery of the lens 10, and the second film layer 50 is formed on the surface of the back paint layer 15 away from the reflective layer 13 and corresponds to the back paint layer 15, and the first film layer 30 cooperates with the second film layer 50 to cover the periphery of the lens 10 and its backing layer 15. The material of the second film layer 50 is different from the material of the first film layer 30. The material of the first film layer 30 may be selected from one or two of an epoxy resin, a phenol methane resin, and an acrylic resin. The first film layer 30 has a thickness of 100 to 400 nm. The material of the second film layer 50 may be selected from one or more of a polypropylene resin (PP), a polyethylene resin (PE), a polyvinyl chloride resin (PVC), and a polyethylene terephthalate (PET). Kind. The second film layer 50 has a thickness of 100 to 400 nm. Although the first film layer 30 has a better coating effect on the periphery of the lens 10, the first film layer 30 is relatively brittle, and the first film layer 30 is also susceptible to chipping when the lens 10 is broken. A second film layer 50 having better toughness is provided, and the fragments can adhere to the second film layer 50 when the lens 10 is broken to reduce the safety hazard caused by the fragments of the lens 10.

Referring to FIG. 2, in the embodiment, the first film layer 30 is bonded to the surface of the back paint layer 15 away from the reflective layer 13 and covers the periphery of the lens 10. The second film layer 50 is bonded to the first film. The layer 30 is remote from the surface of the backing layer 15 and is provided with a backing layer 15.

Referring to FIG. 3 , in another embodiment, the second film layer 50 is bonded to the surface of the back paint layer 15 away from the reflective layer 13 . The first film layer 30 covers the lens 10 and the second film layer 50 . The periphery.

Referring to FIG. 4, in another embodiment, the first film layer 30 covers the periphery of the lens 10 and is bonded to a region of the back paint layer 15 away from the surface of the reflective layer 13 near the periphery, and the second film layer 50 is combined. A first film layer 30 is disposed between the peripheral layer of the backing layer 15 away from the reflective layer 13 and the peripheral region of the second film layer 50 and the backing layer 15.
