Abstract
The present invention relates to a method for manufacturing single-sheet toughened fireproof glass, which comprises the steps: potassium salt solution is sprayed on the surface of glass with edges finely ground; the glass is chemically toughened in a heat processing furnace after being dried; then physical toughening is carried out; and a PET (polyethylene terephthalate) low-radiation film is stuck on the glass. Compared with the prior art, the method for manufacturing single-sheet toughened fireproof glass has the advantages that the processing time is shortened, and the fireproof performance of the glass is enhanced. Meanwhile, the glass has the advantages of high safety of a toughened interlayer, energy saving, beautiful appearance and comfortable use.
Description
The present invention relates to a kind of making method of strengthened refractory glass, belong to the building glass technical field.
Present mass-produced flame resistant glass all is to fill fire retardant material between two sheet glass, be divided into two kinds on compound (dry method) and sound insulation type (wet method), two kinds of flame resistant glass disadvantages are: after using for some time, cementing layer can go out bubble (or the big micro bubbles of needle point occurring), glass is thick and heavy, transmittance is low, and production efficiency hand-manipulated is low.
The high-strength refractory Cs-K glass that patent CN00118950 introduces, because the rotation of roller in the annealing furnace is affected flame resistant glass lower surface chemical tempering process, and also bigger to the corrosion of annealing furnace roller.
The manufacture method of the silicate fire-resisting glass that patent CN01124523 introduces, because the chemical tempering process is to carry out in traditional saltpetre fused salt groove, the production time, long-acting rate was low, contaminate environment should not be produced big plate face flame resistant glass.
The present invention is that the glass surface on the correct grinding limit carries out the potassium salt soln spraying, and chemical tempering is carried out in dry back in heat treatment furnace, then physical toughened, thereby has improved the fire resistance of glass.
Chemical tempering of the present invention is to adopt spraying coating process, the implementation process of spraying coating process is very simple, at the glass surface of handling through selected, cutting, correct grinding limit, cleaning-drying, spraying potassium salt soln drying and forming-film, sodium ion in heat treatment furnace in the potassium ion of the solid-phase reagent layer displacement glass surface, produce the crowding phenomenon of upper layer, make upper layer produce bigger stress, because the time is short, temperature is low, the present invention adds ion-exchange promotor, masking liquid tackifier, stripper, anion surfactant, makes ion-exchange reach ideal state at short notice.
Potassium salt soln weight proportion of the present invention is:
Sylvite: 30～65%
Sodium salt: 0.5～4%

Thermal treatment temp of the present invention is 400～600 ℃, treatment time is 0.25～3 hour, for improving heat treatment efficiency, heat treatment furnace adopts the hot air circulation heating, and glass stands up, between leave distance, even to guarantee the glass-board surface temperature, the potassium ion of double-sided glass solid-phase reagent layer is replaced the sodium ion of glass surface better, and spraying and heat treatment process also can repeat, to satisfy the particular requirement to the glass surface stress.
Of the present invention physical toughened be that the glass after the thermal treatment is sent into annealing furnace process furnace internal heating through cleaning-drying through potassium salt soln spraying, arrive softening point temperature after, carry out chilling with cold wind, the value of compressive stress of glass surface is reached more than the 200MPa.
