Abstract
A manufacture method of vacuum glass belongs to the glass manufacturing technology field, including steps as follows: a piece of sheet glass and a piece of convex glass are cut according to requirement, and edging process is implemented according to requirement; a lined adhesive glass film is adopted to overlap the surrounding edges of the sheet glass and the convex glass and then is put on a glass fixture into a vacuum lined adhesive furnace, which is pumped to be vacuum. The furnace is heated for 1-3h at 140-160 degree Celsius to fuse the glass and the film; the glass is taken out of the furnace after being cooled naturally, and protective sealant is used to seal and reinforce the vacuum glass. The production process of the invention is easy to be operated and is constructed through connecting the convex glass and the sheet glass directly, which leads to the more stable support in the hollow region of the two-layer glass. The lined adhesive glass film adopted for the sealing of the surrounding edges has the advantages of strong heat resistance and cold resistance and high mechanical strength and can keep various physical performance indexes within the range of 40 degree Celsius subzero to 120 degree Celsius above aero stable. Vacuum glass can be pumped sealed in batches to realize the highly efficient production.

Embodiment
Main body glass adopts 3mm or 5mm float glass master goods, and clean such as decontamination are carried out on the surface, adopts UV printing ink at main body glass surface wire mark, and ink solidification after the irradiation of UV light fixing apparatus constitutes salient point 3.Or adopt sintered type glass colored glaze seal material at main body glass surface wire mark, and put into process furnace 600 ℃ of left and right sides sintering temperatures 1~2 minute, constitute salient point 3.Salient point 3 height can be selected according to the thickness of its distribution density and main body glass, with the ratio of main body thickness of glass generally with 1: 10-1: 3 are advisable.The height that adopts this proportional range that salient point is set can make support more stable, the strength of glass height.Being directly used in vacuum glass after the salient point glass 1 that production obtains cuts by dimensional requirement makes.Also can adopt sintered type glass colored glaze seal material at main body glass surface wire mark, put into glass tempering furnace after cutting by dimensional requirement, in toughened glass, reach seal material sintering purpose, make toughened glass with salient point 3.
Cut salient point glass 1 and sheet glass 2 as required, the one side of salient point glass 1 band salient point 3 is pressed on the sheet glass 2, glass carries out the processing of tempering or edging on demand, interlayer surrounding edge at two blocks of glass adopts doubling glass film 4 surrounding edges then, and the doubling glass film is PVB film or EVA film.
The rubber roll shaft that is placed on preformer after glass and film are superimposed is uploaded and is sent preformer to and heat precompressed.Behind the glass lamination, in the glass fixture shown in Figure 3 of vertically packing into.Glass fixture comprises bracing frame 5, and bracing frame 5 is equipped with one group of grid 8, and grid 8 one sides are provided with pressing plate 10 by pretension bolt 9 connections, and pressing plate 10 outsides are equipped with by refuting and connect compression plate 11, precession screw rod 12, control the clamp mechanism that motor 13 connects and composes.Clamp button 7 with glazing gasket and clamp glass laminations 6 surrounding edge places, between adopt grid 8 to separate to come, after glass is filled, fixing with pretension bolt 9, and pretension refutes and connect compression plate 11, and glass is sent into vacuum doubling stove evacuation to reaching 0.08-0.1Pa, and is best for reaching 0.1Pa.Wait to vacuumize reach requirement after, use control motor 13 and precession screw rod 12 to compress to refute and connect compression plate 11 and make pressing plate 10 compress grid 8, glass lamination 6 obtains certain mechanical pressure, glass and film are adjacent to, in stove, heat 1.5-2.5h, generally be advisable, keep 140 ℃-160 ℃ of working temperatures with 2h, through experimental test is optimal working temp for 150 ℃, and glass and film are merged.Shift out vacuum doubling stove behind the vacuum glass naturally cooling, technology is carried out sealing and reinforcing with the protection seal gum to circumference of vacuum glass routinely, can finish the making processes of vacuum glass.
This vacuum glass also can adopt following method to make: aspirating hole 14 is set and by unified technical size setting on a minor face of interlayer periphery, the glass edge at the aspirating hole place edging of going ahead of the rest is handled, so that aspirating hole has certain cavity outward.The rubber roll shaft that is placed on preformer after glass and film are superimposed is uploaded and is delivered to the pressurization of preformer internal heating, through being placed into autoclave after the precompressed glass and film is merged.Behind the glass plate heat de-airing; the glass in batch that to vertically place according to laying method is as shown in Figure 5 sent into vacuum chamber and is vacuumized; adopt mechanism to smear or inject photocuring seal gum sealing aspirating hole then; shift out vacuum chamber after adopting ultraviolet light modulation to finish photocuring again; with the protection seal gum sealing and reinforcing is carried out in the outside, can form vacuum glass.Because aspirating hole 14 is by unified technical size setting, so can guarantee that aspirating hole is on a level attitude after glass closes sheet, the operation of adopting mechanism to smear or inject photocuring seal gum sealing aspirating hole is more prone to, and the scope of operation of ultraviolet light modulation is little, has improved production efficiency.
Glass and film merge the back whole clearing, can strengthen the width of surrounding edge sealing, the airtight quality that can obtain more to guarantee.Do not use toughened glass may anneal or the high temperature of explosion in the sealing-in process of present method, so this method can adopt tempering or bend glass to be combined into vacuum glass.The most of operation of this method for sealing is stayed vacuum chamber and is carried out outward, makes vacuum office operation simple and fast, and glass placement way takes up room little, but and job stacking, the production efficiency height.As using the wide vacuum chamber of 2m, the glass plate that single enters the chamber can reach 100m
2More than, annual production can reach 500,000 m
2More than.
