Embodiment 1

[0033] A method for producing scratch-resistant tempered glass with a surface coating, comprising the following steps:

[0034] (1) Put the glass into the tempering furnace and keep it warm for 20-30 minutes at 580°C-600°C, then lower the temperature in the furnace evenly to 200-220°C within 30 minutes, and keep it warm for 10-15 minutes after dropping to 200-220°C ;

[0035] (2) Take the glass out of the furnace and apply a layer of paint, the paint is made of the following raw materials,

[0036] Metasilicate 5-10kg, TMPTA 15-25kg,

[0037] Alumina 1-4kg, polyethyl acrylate 18-30kg,

[0038] 5-12kg pyrosilicic acid, 85-90kg glycerol,

[0039] PETA 15-25kg, calcium oxide 2-5kg,

[0040] Carbon fiber 0.5-3kg.

[0041] (3) Put the glass coated with paint in step (2) into molten potassium nitrate salt for 15-20 minutes;

[0042] (4) Immerse the glass in step (2) in hot water at 80-90°C for 8-10 minutes;

[0043] (5) Take out step (4) and let it cool naturally.

Abstract

The invention discloses a manufacturing method of anti-scraping toughened glass. The manufacturing method comprises the following steps: (1) conveying glass into a tempering furnace, keeping the temperature at 580-600 DEG C for 20-30 minutes, uniformly reducing the temperature in the furnace to 200-220 DEG C within 30 minutes, and keeping the temperature for 10-15 minutes after the temperature isreduced to 200-220 DEG C; (2) taking out the glass from the furnace, and then coating the glass with a layer of a coating, wherein the coating is prepared from the following raw materials: 5-10 partsof metasilicic acid, 15-25 parts of trimethylolpropane triacrylate (TMPTA), 1-4 parts of aluminum oxide, 18-30 parts of poly(ethyl acrylate), 5-12 parts of pyrosilicic acid, 85-90 parts of glycerol, 15-25 parts of pentaerythritol triacrylate (PETA), 2-5 parts of calcium oxide and 0.5-3 parts of carbon fibers; (3) putting the glass coated with the coating in the step (2) into potassium nitrate molten salt for reacting for 15-20min; (4) putting the glass in the step (2) into hot water with a temperature of 80-90 DEG C for immersion for 8-10min; and (5) taking out the glass obtained in the step (4), and carrying out natural cooling to obtain the toughened glass. The manufacturing method has the characteristic of enhancing anti-scraping performance of glass.

Description

technical field [0001] The invention relates to the field of glass processing, in particular to a method for manufacturing scratch-resistant tempered glass. [0002] technical background [0003] Tempered glass has been widely used due to its advantages such as high mechanical strength, excellent thermal shock resistance, and good safety. Most of the existing tempered glass production processes adopt the tempering process using air as the cooling medium, so that the heated glass is subjected to chilling treatment in a short period of time through a large amount of air, thereby completing the tempering process. In order to ensure the performance of tempered glass, it is usually necessary to provide a large flow of air in a short period of time, especially when tempering thin glass. Usually, a high-power fan with high wind pressure and large flow is used to blow air at the same time. [0004] At present, the surface strength and hardness of glass tempering are not ideal, and i...
