Description
Technical field
The invention relates to a kind of composition and enhancement method that glass is strengthened, the chemical enhancing composition and the enhancement method of more specifically saying so and ultra-thin silicon-dioxide coating glass being strengthened about a kind of.
Background technology
Glass is a kind of hard brittle material, and its tensile strength is very low.The intensity of hard brittle material depends on its surface tissue to a great extent, though it is very complete smooth that the surface of glass seems, in fact has a large amount of tiny cracks, these tiny cracks are under the tension stress effect, originally be that crackle enlarges, will begin to break from the surface then.Therefore, if can eliminate the influence of these crizzles, the tensile strength of glass just can significantly improve.Because there are various defectives in self structure and the production technique in glass, make the actual tensile strength of glass far below theoretical strength.In order to improve glass intensity, just need carry out secondary processing to glass, that is, glass is strengthened.The enhancement method of glass roughly can be divided into two classes, and a class is a physical method, and a class is a chemical process.
Physical strengthening method is meant a glass heats, when glass begins to soften, and the cooling of coming out of the stove rapidly, the outside surface of glass at first cools off hardening, has so just formed toughened glass.But the toughened glass (perhaps half tempered glass) that obtains through physical strengthening method can not cut, when bump that is subjected to sharp object or scuffing, can be easier to be more cracked than simple glass, and broken back forms the fine grained chippings of no sharp keen corner angle.
Chemical enhanced method is broadly divided into three kinds: ion exchange method, hydrofluoric acid etch and glass surface coating.In these three kinds of methods, be most widely used with ion exchange method, the condition of this enhancement method is simple, and strengthening effect is remarkable.Ion exchange method can be divided into two kinds of high temperature ion exchange method and low-temperature ion exchange processes again.The high temperature ion exchange method is meant that the temperature of ion-exchange is more than the softening temperature of glass, high temperature ion-exchange has two types usually: first type for being strengthened by extrusion effect, promptly exchange small ion with heavy ion, second type strengthens for the surface produces the low bulk crystallization, this is the low-expansion coefficient crystallite that utilizes ion-exchange to produce at glass surface, because the coefficient of expansion of the glass surface after the exchange is lower than the coefficient of expansion of glass inside, can produce stress after the cooling, thereby reach the enhanced purpose.But because the high temperature ion exchange method is to carry out more than the softening temperature of glass, therefore at high temperature, glass is easy to generate distortion, and therefore causes the damage of optical property, and high temperature also can cause more energy consumption.The low-temperature ion exchange process is meant that ion-exchange occurs in below the softening temperature of glass, glass is immersed in the high-temperature molten salt of ionic radius greater than the alkali metal compound of contained alkalimetal ion in the glass, or with the solution spraying of salt on the heated glass surface, the ion that the glass surface volume is little is just replaced by bulky ion in the exchange fused salt then.After glass cools, glass network is shunk, bulky ion needs bigger space, thereby make glass surface produce racking stress, and the inner tension stress that produces, form the compressive layer of glass surface densification thus, the existence of compressive layer has reduced the tiny crack of glass surface, thereby reaches the effect of reinforcing glass intensity.
CN1162363C discloses a kind of production technique of chemically toughened glass, this technology is to add potassium hydroxide in the saltpetre fused salt, aluminium sesquioxide and diatomite additive, make the saltpetre fused salt, the usage ratio of additive is: with potassium hydroxide/saltpetre weight percent is 1, aluminium sesquioxide/saltpetre weight percent is 10-30, the weight percent of diatomite/saltpetre is 100-150, the saltpetre fused salt mixt that configures is heated to 400-500 ℃ of insulation, to clean in advance, the glass that oven dry is good is preheating to 350 ℃, constant temperature 30 minutes, glass is immersed in the fused salt, constantly under 400 ℃ temperature, after 3-8 hour glass is slowly taken out from fused salt, enter in the very approaching annealing furnace of a temperature and temperature of molten salt and be annealed to room temperature.Although this production technique can effectively improve glass intensity, the chilled glass that adopts this processing method to obtain is a toughened glass, can't cut at all.
The thickness of ultra-thin silicon-dioxide coating glass that is applied to flat-panel monitor is generally the 0.3-1.1 millimeter usually below 2 millimeters, because of its intensity is obviously not enough, when carrying or improper use disrepair phenomenon may take place.As: the STN-ITO conductive glass is made up of thin float glass, silicon dioxide film and ITO (tin indium oxide) film, wherein, the effect of silicon dioxide film is as transparent barrier-layer, its effect is the alkalimetal ion that stops in the glass, mainly be the infiltration and the diffusion of sodium ion, the performance of flat-panel display device exerted an influence preventing.If desired this kind glass is carried out chemical enhancedly, then need before ITO is coated with, carry out, otherwise strengthening process can cause than macrolesion the ITO film.And after adopting general physical method or chemical process to strengthen, intensity takes place and does not rise anti-phenomenon of falling in ultra-thin glass easily, and can not cut normally, and cutting is the necessary operation in the panel display board making.If the improper meeting of treatment formulations and method causes some negative impacts to the silicon dioxide film of silicon-dioxide coated glass, as: degradation under sticking power reduction, the transmittance, and the described processing method of CN1162363C still is not suitable for flat-panel monitor is strengthened with ultra-thin silicon-dioxide coating glass, therefore flat-panel monitor is had higher requirement with the reinforcement of ultra-thin silicon-dioxide coating glass.
Summary of the invention
The method that the objective of the invention is to solve the chilled glass of prior art is not suitable for the defective that flat-panel monitor is strengthened with ultra-thin silicon-dioxide coating glass, be used for glass and provide a kind of, particularly composition and the enhancement method that flat-panel monitor is strengthened with ultra-thin silicon-dioxide coating glass.
