Abstract

The invention discloses preparation technology of high-precision glass light guide plate. The preparation technology comprises the following steps: (1) pretreatment of glass powder: 4J29 kovar alloy and 7070 glass are selected as materials, and the 7070 glass is grinded into glass powder; preparation of materials: the glass powder, paraffin and oleic acid are weighed according to a proportion 50:10:1; (3) slurry mixing: paraffin is placed in a stainless steel kettle for heating and melting, dried glass powder is immediately poured into the paraffin solution, oleic acid is poured into the solution at the same time, and insulation is carried out till the solution is in slurry shape; (4) hot pressure casting: the prepared slurry is poured into a hot pressure casting cylinder for pressure casting; (5) wax absorption: dregs in glass blanks after pressure casting are sieved, the glass blanks are uniformly placed in a wax absorbing tray, the tray is placed in a baking oven for heating and natural cooling. (6) de-waxing and vitrification: the blanks after pressure casting are sintered into glass blanks of a certain dimension and hardness, primary selection of the blanks after de-waxing is carried out, the blanks are horizontally placed in a stainless steel box, and de-waxing and vitrification are carried out in a muffle furnace; (7) examination and screening; (8) sintering and moulding; (9) polishing.

Description

technical field [0001] The invention relates to the technical field of glass light guide plate preparation, in particular to a preparation process of a high-precision glass light guide plate. Background technique [0002] The LightGuidePlate is the light guide efficiency center of the overall backlight module. Its principle is to use the dot distribution (pattern) on the bottom of the light guide acrylic plate to destroy the interference phenomenon of light, and evenly guide the line light source into a surface light source. It is a key part of the key part of the LCD and even the backlight source. With the rapid development of the LCD market, the requirements for the manufacture of light guide plates have become industrialized. This will make the manufacture of the light guide plate develop towards the direction of stability of luminance and luminance distribution, higher yield, higher production efficiency and lower production cost. The injection molding technology of th...
