(2) the patterns are fine and exquisite;

(3) the pattern does not discolor or fall off.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail below.

The method mainly comprises the following steps:

example 1:

1) selecting and manufacturing glass meeting the specification:

in view of the high demand of glass for colored drawing, it is necessary to process commercially available glass to meet the processing requirements, and in particular, there are different requirements for the size of glass, and it is necessary to perform preliminary selection and rough processing of glass, such as: for different thicknesses of glass, different slices are used, for example, for thicknesses above 12mm, a diamond glass wet slice with a Φ 300x2mm, 25.4mm hole can be used. Cutting glass of such thickness using such a slice is the most economical option; as for the glass with the thickness of less than 12mm, a Japanese diamond glass cutting knife is used for cutting; and then grinding and polishing the sliced or cut glass to the same horizontal height by using a grinder, a straight edge machine or a pressure bar flat grinder, wherein the grinder or the pressure bar flat grinder is ground by using carborundum W40. In the grinding and polishing process, glass with a thickness of 25mm or less can be ground into long strips by a straight edge machine, and then the long strips are cut into required sizes by a diamond slice or a Japanese diamond glass cutting knife and ground and polished.

For the glass with thinner thickness and smaller thickness, the glass can be shaped directly by using a forming machine and then polished by using a compression bar flat grinder to form a square.

Wherein the shape and color of the glass can be freely selected according to the actual situation, which is well known in the art.

(2) Manufacturing a protective film:

the desired pattern was drawn on a computer using Adobe Illustrator drawing software onto the protective film using a Pantone format book. Then cutting the patterns in the protective film with the drawn patterns by using a computer character cutting machine; meanwhile, if the processed pattern is too small, the line can be amplified by Corel Draw software instead, and trial cutting processing is carried out, and mass production is carried out after no problem exists.

The protective film is a plastic film, for example, a plastic film made of PE, PVC and other plastics can be adopted.

(3) Pasting a protective film:

and (3) attaching the cut protective film to the position required by the glass, and fixing, for example, blowing hot air to the surface of the protective film by using a hot air gun so that the protective film is firmly attached to the surface of the glass.

(4) And (3) removing the protective film pattern:

picking out the cut pattern from the surface of the glass, so that the exposed surface of the glass is the pattern to be subjected to sand blasting, and cleaning the protective film by using a cleaning agent to prevent the picked protective film from leaving plastic particles, thereby influencing the effect of subsequent sand blasting;

(5) sand blasting pattern:

blasting sand on the glass with the protective film pattern removed by using a sand blasting machineThe pedal control floor type sand blasting machine with stable jet flow is adopted, and the pressure is 6bar (kg/cm)²) The flow rate was 1.0m³Dry compressed air,/min, with a 4.5mm iron nozzle, which was used in conjunction with carborundum to spray patterns.

(6) Cleaning glass:

after the sand blasting, the glass is cleaned, for example, the sand blasted glass is put into an ultrasonic cleaning machine for cleaning. The ultrasonic cleaning machine utilizes high-frequency ultrasonic oscillation with the oscillation frequency of 40000 times/second (40KHZ shaking head) and liquid trichloroethylene as a transmission medium. Because ultrasonic waves are a compressive longitudinal wave, they can push the trichloroethylene through pressure changes to generate countless tiny vacuum bubbles, causing cavitation. When the bubble pressurized blasting, can produce powerful impact force, produce blasting and regeneration numerous times in the twinkling of an eye to will be attached to glass surface, concave position or the quick glass that leaves of grease, dirt of hidden department, finally reach thoroughly clean effect, also can not damage glass simultaneously, also make subsequent oiling can not appear droing, blushing, spot or bubble.

(7) And (3) drying:

the ultrasonic cleaning machine uses liquid trichloroethylene as a transmission medium, so that the glass needs to be dried, namely, the glass is dried by using an oven; of course, other means of drying may be used to facilitate subsequent processing.

(8) Oiling:

after drying, the glass is oiled. The ink used may be a coloured ink. The ink is stable to allow firm fixing to the glass. This example used a lead-free low temperature environmentally friendly glass ink from Marabu glaster, germany, to coat the surface of glass. The lead-free low-temperature environment-friendly glass ink of the Marabu Glaster company in Germany has the advantages of saturated color, sufficient color system, strong adhesive force, fading resistance, wind corrosion resistance, friction resistance, scratch resistance, low-acid resistance, alkali resistance, alcohol resistance, sweat water resistance, gasoline resistance, battery solvent resistance and the like.

(9) And (3) drying the printing ink:

the glass coated with the ink was baked using an oven at 150 ℃ for 15 minutes. Meanwhile, an oven is not needed, and natural drying is also available, so long as 48 hours is not needed.

(10) And (3) tearing off the residual protective film:

and tearing off all the residual protective film from the surface of the glass, thereby completing the sand blasting glass with the stereoscopic impression pattern.

Example 2:

this embodiment is different from embodiment 1 only in that: after the above steps of embodiment 1, the method further comprises a bonding step, namely bonding two pieces of glass or three pieces of glass, specifically: and coating colorless and transparent viscous liquid on the sand-blasting oiled pattern, and bonding the glass together by using ultraviolet glue after curing. The transparent glue is Aihe AH-510A glue, the curing temperature is normal temperature, and the curing time is 24 hours.

In the embodiment, the transparent glass is bonded on the colored drawing glass, so that the colored drawing glass is more attractive and has characteristics.

Example 3:

this embodiment is different from embodiment 1 only in that: the pressure adopted by the sand blasting machine in the step (5) is 5 bar (kg/cm)²) The flow rate was 0.8m³The vibration frequency of the ultrasonic waves in the step (6) is 28000 times/second (28KHZ vibration head) for dry compressed air/min.

Example 4:

this embodiment is different from embodiment 1 only in that: the pressure adopted by the sand blasting machine in the step (5) is 7bar (kg/cm)²) The flow rate is 1.2m³The vibration frequency of the ultrasonic waves in the step (6) is 40000 timesSecond (40KHZ shaking head).

While the invention has been described in connection with what is presently considered to be the most practical and preferred embodiment, it is to be understood that the invention is not to be limited to the disclosed embodiment, but on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
