Embodiment 1

[0027] As shown in the accompanying drawings: a method for preparing a moyu black tempered glass cover plate, comprising the following steps:

[0028] The first step is to cut the material: the glass is cut into the required size glass piece;

[0029] The second step, CNC: punch holes and / or open steps on the glass sheet; punch holes and / or open steps on the glass sheet with a laser cutting machine, and set the program of the laser cutting machine in advance during the cutting process to improve cutting efficiency and precision, to avoid problems such as cracking, burrs and breakage of the glass sheet during the cutting process;

[0030] The third step, cleaning: ultrasonic cleaning;

[0031] The fourth step, tempering: strengthen the cleaned product, KNO at 400°C 3 Tempered in solution; glass sheet in KNO 3 Tempering in the melt for 3 hours;

[0032] The fifth step, rejecting defective products: check whether the product is qualified, and remove unqualified products; chec...

Embodiment 2

[0038] A method for preparing a moyu black tempered glass cover plate, comprising the following steps:

[0039] The first step, material cutting: the glass is cut into the required size glass sheet, and the glass sheet is further polished after opening to make the surface smooth and the thickness uniform and moderate, so that the thickness is between 400-700nm; preferably, The thickness of the glass sheet is 500-600nm; more preferably, the thickness of the glass sheet in this implementation is 550nm.

[0040] The second step, CNC: punch holes and / or open steps on the glass sheet; punch holes and / or open steps on the glass sheet with a laser cutting machine, and set the program of the laser cutting machine in advance during the cutting process to improve cutting efficiency and precision, to avoid problems such as cracking, burrs and breakage of the glass sheet during the cutting process.

[0041] The third step, cleaning: use ultrasonic cleaning, and use an ultrasonic machine ...

Abstract

The invention provides a preparation method of a dark jade black tempered glass cover plate. The preparation method comprises the steps of 1, cutting; 2, conducting CNC; 3, cleaning; 4, tempering; 5, rejecting defective products; 6, conducting silk-screen printing, specifically, arranging a dark jade black ink layer on the surface of a glass sheet in a silk-screen printing mode; 7, conducting UV light curing, specifically, irradiating the ink layer by utilizing UV light so as to rapidly cure the ink layer; 8, drying, specifically, heating in an oven at the temperature of 160-170 DEG C for 15-17 minutes to increase the thermal stability and prevent the phenomenon of decoloration; and 9, packaging. According to the scheme, complex production procedures are effectively reduced, the production efficiency and quality of products are improved, meanwhile, the service life of the glass sheet can be prolonged, the bearing capacity of the glass sheet can be improved, the glass sheet is prevented from being broken due to strong pressure, hydrophobic, lipophobic and fingerprint-proof effects are achieved, the ink layer is added to the glass sheet, the use attractiveness effect of the glass sheet is effectively improved, blue light can be absorbed at the same time, and harm of strong light to eyes is reduced.

Description

technical field [0001] The invention relates to a manufacturing process of a tempered glass cover, in particular to a method for preparing a moyu black tempered glass cover. Background technique [0002] The glass cover is the protective glass. As an important part of the touch device, the glass cover is mainly used to protect the LCD, with good light transmission performance and decorative appearance. The main properties are: excellent surface finish; extremely high surface hardness and super scratch resistance; excellent metal visual effect, high hardness of white surface. [0003] Tempered glass is tempered glass. It uses physical or chemical methods to form a compressive stress layer on the surface of the glass. The glass itself has high compressive strength and will not cause damage. The tempering of glass generally adopts the method of chemical tempering. The elasticity, thermal stability, and thermal shock of tempered glass are much better than ordinary glass. How...
