Description

A kind of preparation method of vacuum glass

Technical field

The present invention relates to a kind of preparation method of vacuum glass, belong to the building materials field of energy-saving technology.

Background technology

China is a big developing country, is again a building big country, and annual newly constructed house area surpasses the summation that all developed countries build up building area every year up to hundred million square metres of 17-18.At present, China's building energy consumption has accounted for 40% of whole society's total energy consumption; And the door and window energy consumption accounts for 45%～50% of building energy consumption, will become the building energy conservation emphasis according to the following door and window power-saving technology of relevant scholarly forecast.

The effect that door and window has daylighting, ventilates and goes along with sb. to guard him also plays a part very important on art of building is handled.Yet door and window is again the position of causing energy loss the most easily.In order to increase the character trait of lighting and ventilation area or performance modern architecture, the door and window area of building is increasing, and all-glass curtain buildings is more arranged.This just external the energy-conservation of enclosed structure is had higher requirement.At present, the energy-efficient treatment to door and window mainly is to improve the thermal and insulating performance and the airtight performance that improves door and window of material.From sash stuff, the higher energy-conserving products of some technology contents such as the disconnected hot profiles of aluminium alloys, aluminium-wood composite section, steel plastic integral extrusion profile, plastic-wood composite section and UPVC plastic material had appearred in recent years.What wherein use was wider is the UPVC plastic material, and its employed raw material is a macromolecular material--RPVC.It is less energy consumption, pollution-free in the manufacturing process not only, and material thermal conductivity is little, multi-cavity body structure good airproof performance, thereby thermal and insulating performance is good.The UPVC plastic door-window has adopted for many years in European various countries, has accounted for 50% at German plastic door-window.China after the nineties in 20th century plastic door-window consumption constantly increase, replace the big materials of energy consumption such as steel, aluminium alloys just gradually.Cause the excessive problem of energy loss in order to solve large-area glass; People have used new and high technology; Simple glass is processed into hollow glass, and coated glass (comprising reflective glass, heat absorbing glass) high strength LOW2E flame resistant glass (the low-emission coated flame resistant glass of high strength), employing magnetic control vacuum sputtering method are coated with the glass and the most special intelligent glass of containing metal silver layer.The variation of intelligent glass ability perception ambient light is also made a response, and it has two types, and one type is photochromic glass, when illumination is penetrated, and glass meeting sensitization deepening, light is difficult for seeing through; When stopping illumination and penetrating, glass is recovered lost eyesight, and light can see through.When sunshine is strong, can intercept solar radiant heat; When it was cloudy, glass brightened, sunshine again can inlet chamber in.Another kind of is electrochomeric glass, on two sheet glass, is coated with conducting film and electrochromic substance, through regulation voltage; Impel the electrochromic substance variable color; The sunshine that adjustment is injected (but because of its cost of production is high, can't actually using now), these glass all have good energy-saving effect.

Hollow glass is used morely in building trade at present, owing to still have air to exist in the hollow glass, still there is certain problem in its effect of heat insulation.If can make hollow glass into vacuum glass (interior hollow is vacuum); Since vacuum layer to the blocking effect of conduction of heat and sound wave conduction with and eliminated the cross-ventilation heat transfer in the vacuum layer, so vacuum glass has than the better effect of heat insulation of hollow glass, energy-saving effect and soundproof effect.

Yet there are problems such as complex manufacturing, equipment investment are big, cost of production height in existing vacuum glass, has influenced applying of vacuum glass.

Summary of the invention

The objective of the invention is, problems such as the vacuum glass equipment investment is big in order to solve, cost of production height disclose a kind of preparation method of vacuum glass.

Technical scheme of the present invention is on the basis of hollow glass production technology, a light-permeable plastic support frame to be set between two blocks of sheet glass; And a plurality of raw rubber joints in order to vacuumize are set at light-permeable plastic support frame periphery; Press the light-permeable plastic support frame edge filling fluid sealant of hollow glass production technology, only expose the raw rubber blank area at two blocks of sheet glass, treat filling adhesive curing drying after; Insert the hollow pin of bleeding from the raw rubber joint; The needle point hole depth of bleeding is gone into the space between two sheet glass, through the pin of bleeding, extracts the air between two blocks of sheet glass; After the vacuum between two sheet glass reached the regulation requirement, the pin of will bleeding was extracted out rapidly, adds fluid sealant in the raw rubber joint then, and it is dry to let it solidify.

The step of said method is:

(1), is made into the light-permeable plastic support frame of suitable dimension according to the size of vacuum glass; But the open slot of one or more embedding raw rubber joints is left in the plastic frame surrounding of light-permeable, is distributed with vent notch or aperture on every grid plastic sheet in the framework, is convenient to framework Nei Gege intercommunication;

(2) in the open slot of the plastic frame surrounding of light-permeable, embed the raw rubber joint;

The light-permeable plastic support frame that (3) the raw rubber joint will be housed places correct position between two blocks of sheet glass, is fixed and clamped;

(4) filling fluid sealant between the edge of two blocks of sheet glass and light-permeable plastic support frame periphery only exposes the raw rubber blank area, keeps the inside of two blocks of sheet glass and outside air to completely cut off;

(5) treat filling sealing glue solidifying drying after, insert the pin of bleeding respectively from each raw rubber joint, the needle point hole depth of bleeding is gone into the space between two sheet glass, through the pin of bleeding, extracts the air between two blocks of sheet glass; The air of the grid of framework central authorities is progressively extracted out through air channel;

(6) after the vacuum between two sheet glass reached the regulation requirement, the pin of will bleeding was extracted out rapidly, adds the filling fluid sealant in the raw rubber joint then, and it is dry to let it solidify, and accomplished vacuumizing operation.

Because raw rubber has very strong elasticity, in the process that vacuumizes, do not have air and leak; Exhaust vacuum and extract when bleeding pin, also do not have air and get into.After the pin of bleeding was extracted, the place added fluid sealant at raw rubber, can guarantee the sealing of vacuum glass fully.

The beneficial effect of the present invention and prior art comparison is; Adopt this method to make the production technology of vacuum glass former hollow glass capable of using; Need only between two blocks of sheet glass, increase the light-permeable plastic support frame that is embedded with elastomer connector, this method is simple to operate, and is with low cost.

The present invention is suitable for the manufacturing of vacuum glass.
