Description

Glass product

The present invention relates to a glass article.

Glass products such as mirrors are very common in life. However, in the summer or autumn and winter seasons, due to the large temperature difference between the interior and the exterior of the building, the water vapor in the air easily condenses on the surface of the glass product to lower the light transmittance of the glass, causing trouble to the user.

In view of this, it is necessary to provide a glass article. The glass article includes a hydrophilic film, a glass substrate, a reflective layer, and a protective layer which are sequentially laminated. The hydrophilic film covers one side of the glass substrate. The reflective layer is located on the opposite side of the glass substrate from the hydrophilic film. The protective layer is located on a side of the reflective layer away from the glass substrate and covers the reflective layer.

Compared with the prior art, the glass article provided by the invention can prevent fogging of the glass surface and bring convenience to life.

The embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

Referring to FIG. 1 and FIG. 2 together, the glass product 100 according to the first embodiment of the present invention includes a hydrophilic film 110, a glass substrate 120, a reflective layer 130, a protective layer 140, and a corrosion resistant layer 150 which are sequentially stacked from top to bottom.

The hydrophilic film 110 covers one side of the glass substrate 120, and the reflective layer 130 is located on the opposite side of the glass substrate 120 opposite to the hydrophilic film 110. The protective layer 140 is located on a side of the reflective layer 130 away from the glass substrate 120 and covers the reflective layer 130 . The corrosion resistant layer 150 covers at least a portion of the protective layer 140 to protect at least a portion of the reflective layer 130 from being corroded by oxygen and moisture in the air.

Specifically, the glass substrate 120 includes a first surface 121 and a second surface 122 on the opposite side. The first surface 121 is parallel to the second surface 122. The hydrophilic film 110 covers the first surface of the glass substrate 120. 121. The reflective layer 130 covers the second surface 122 of the glass substrate 120. The protective layer 140 covers the surface of the reflective layer 130 away from the glass substrate 120. The corrosion resistant layer 150 covers at least a portion of the protective layer 140 to protect at least a portion of the reflective layer 130 from being corroded by oxygen and moisture in the air. In this embodiment, the corrosion resistant layer 150 covers the protective layer 140 on the surface of the protective layer 140 away from the reflective layer 130 and covers the periphery, and the reflective layer and the at least part of the sidewall 123 of the glass substrate 120 .

The material of the glass substrate 120 can be selected from any kind of glass, such as soda glass, aluminum. Tellurite glass, etc. The thickness of the glass substrate 120 may be any thickness. In the present embodiment, the thickness of the glass substrate 120 is between 2 mm and 18 mm.

In the present embodiment, the hydrophilic film 110 is a film composed of a sulfonate group of a mercapto group. The hydrophilic film 110 has a thickness of less than 100 nm, a Rockwell hardness of not less than 3H, a heat resistant temperature of not less than 250 degrees Celsius, and an initial water contact angle of less than 10 degrees. In other embodiments, the hydrophilic film 110 can also be constructed from other hydrophilic materials. The hydrophilic film 110 can be formed on the surface of the glass substrate 120 by air pressure spraying, electrostatic spraying, ultrasonic spraying, immersion coating or slit coating.

The reflective layer 130 is made of a material having high reflectivity such as silver, copper, aluminum, and mixtures thereof. The reflective layer 130 reflects light incident from the side of the glass substrate 120 to which the hydrophilic film 110 is attached.

The protective layer 140 is used to protect the reflective layer 130 from being worn. The material of the protective layer 140 may be selected from low lead paints.

The corrosion resistant layer 150 may be selected from a colloid or a high molecular polymer mainly composed of an acrylic resin or an epoxy resin. The corrosion resistant layer 150 has a thickness between 1 and 200 microns.

The hydrophilic film 110 is thin in thickness and does not adversely affect the light transmittance of the glass article 100. Moreover, the hydrophilic film 110 is characterized by high hardness and high heat resistance. During the use, after the water mist is condensed on the glass article 100, the water mist can be automatically collected into the water droplets on the hydrophilic film 110 and slipped from the surface of the hydrophilic film 110, thereby making the glass article 100 less likely to form fog. surface. The protective layer 140 and the corrosion resistant layer 150 can protect the reflective layer 130 from corrosion and prolong the service life of the glass article 100.

Please refer to FIG. 3 , which is a cross section of a glass product 200 according to a second embodiment of the present invention. Schematic diagram. The glazing 200 is similar to the glazing 100 of the first embodiment, that is, the description of the glazing 100 can be substantially applied to the glazing 200, in particular, the hydrophilic film 210, the glass substrate 220, and the reflection.

The main difference between the glass article 200 and the glass article 100 of the first embodiment is that the corrosion resistant layer 250 is located on the surface of the protective layer 240 away from the reflective layer 230 near the edge region and covers the surrounding protective layer 240, The reflective layer and 230 at least a portion of the sidewall 223 of the glass substrate 220 expose a portion of the protective layer 240.

Since the protective layer 240 itself also has a certain degree of corrosion resistance, in the second embodiment, the corrosion resistant layer 250 only wraps the reflective layer 230 and the protective layer 240 for protection. The area near the middle of the protective layer 240 is exposed to save the material cost of the corrosion resistant layer 250, and also serves to protect the reflective layer 230.

The glass article 300 is similar to the glass article 100 of the first embodiment, that is, the description of the glass article 100 can be substantially applied to the glass article 300, in particular, the hydrophilic film 310, the glass substrate 320, and the reflection. The structures of the layer 330 and the protective layer 340 are the same as those of the hydrophilic film 110, the glass substrate 120, the reflective layer 130, and the protective layer 240 of the first embodiment, and will not be described herein. The main difference between the glass article 300 and the glass article 100 of the first embodiment is that the corrosion resistant layer 250 is located on the surface of the protective layer 240 away from the reflective layer 230 near the edge region and covers the protective layer 240, The reflective layer 230, the glass substrate 220, and the sidewall 323 of the hydrophilic film 310 extend until the hydrophilic film 310 is extended A portion of the surface of the glass substrate 320 is exposed, and a portion of the protective layer 240 and the hydrophilic film 310 are exposed.

Since the protective layer 340 itself also has a certain degree of corrosion resistance, in the third embodiment, the corrosion resistant layer 350 exposes a region near the middle of the protective layer 340 to save the corrosion. The material cost of layer 350 also serves to protect reflective layer 330. The structure of the corrosion resistant layer 350 extending from the protective layer 340 to the surface of the hydrophilic film 310 and wrapping the protective layer 340, the reflective layer 330, the glass substrate 320 and the side of the hydrophilic film 310 can prevent the corrosion resistant layer 350 from the glass.
