Abstract
The invention relates to zinc-boron-silicon heat-resisting environmental-friendly emulsion opal glass and a preparation method thereof. The glass is characterized by consisting of the following components in percentage by mass: 68-78% of SiO2, 0-4% of Al2O3, 10-15% of B2o3, 5-8% of ZnO, 0.5-3% of CaO, 0-2% of MgO, 2.5-4.5% of alkali metal oxide and 1-5% of P2O5. The preparation method comprises the steps of: preparing the components into a glass batch and melting; then moulding by casting; and annealing to obtain the emulsion opal glass. The method is environmental-friendly and free of pollution and the glass does not contain fluorine, has less erosion to the refractory matters and is molded in one step; and compared with the conventional emulsion opal glass, the prepared zinc-boron-silicon heat-resisting environmental-friendly emulsion opal glass is low in thermal expansion coefficient, stable in opacification, less in environment pollution, less in corrosivity of refractory matters, high in opacity, less in phosphorus volatilization and good in glossiness.
Description
Technical field
The invention belongs to emulsion opal glass and preparation field thereof, particularly a kind of zinc borosilicate system heat resistant environmental-friendly emulsion opal glass and preparation method thereof.
Background technology
Emulsion opal glass refers in glass the particulate that a large amount of specific refractory power that is scattered here and there is different from host glass, and light is through the glass presenting milkiness during glass because particulate produces refraction or reflect.And when size of particles is reduced to the order of magnitude of incidence visible light wavelength, also produce diffraction milkiness.The particulate of these high dispersive can be glass phase-separating produce drop phase, the crystal of precipitation, the micro-bubble do not drained or even non-melting oxide particle.Particle size produces Mie scattering when being greater than the wavelength of incident light, and present oyster white, the wavelength that particle size is less than incident light then produces the scattering of Rayleigh shellfish, presents blue opalescence.Opaque glass is the one of emulsion opal glass, obtains its name because adding opacifying agent outward appearance in white.Again because opaque glass is white jade shape, can densification be made and there is suitable intensity, automatically cleaning, radiationless thin plate, alternative traditional stupalith and enjoying great popularity.Compared with conventional clear glass, opaque glass, with advantages such as its soft color and luster, graceful outward appearances, is widely used in the various fields such as daily utensil, architectural lighting and cosmetic package, bottle, building and ornament materials and dental material.
Emulsion opal glass is divided into by the difference usually according to opacifying agent in production: Fluoride Opal Glass, Phosphate Opaque Glass, oxide compound emulsion opal glass, vitriol emulsion opal glass, sulfide emulsion opal glass and opalized with the mixture glass etc.At present, domestic and international factory mostly adopts fluorochemical milkiness, often because the volatilization of fluorochemical in glass fusion process, causes the change of milkiness degree, sometimes also has product and becomes situation appearance that is blue, that turn yellow.And fluoro-gas is comparatively large to the murder by poisoning of people, animal, plant, the Law on Environmental Protection of many countries has done strict regulation to the fluorine content in air.
General phosphoric acid salt is for fluorine as opacifying agent both at home and abroad, and but, it is too narrow that phosphoric acid salt makes the milky white scope of opacifying agent, and milkiness degree is unstable, requires harsh to the thermal regulation of operation; Comparatively Fluoride Opal Glass glass melting temperature is high for Phosphate Opaque Glass, and founding power consumption increases to some extent; Similar to Fluoride Opal Glass, also there is volatilization, crystallization and to problems such as the erosions of refractory materials.The patent of current emulsion opal glass is generally divided into phosphoric acid salt milkiness and fluorochemical milkiness two class.
Patent publication No. in 2008 is for described in the patent of CN101234851A being phosphorous and opalized with the mixture glass that is fluorine, and its fluorine added is to refractory corrosion, and harm operator's is healthy, and in practice is produced, economical, societal benefits are lower.Application number in 2009 is the emulsion opal glass of the applicable full electrofusion hot briquetting of 200910238115.3, the fluorochemical of 3-4wt% in described formula, though adopt all-electric melting technology to decrease the volatilization of fluorochemical, the erosion of refractory materials is also greatly reduced to the life-span of kiln.
Although patent publication No. in 2008 for the emulsion opal glass described in the patent of 101182117 not fluorine-containing, but this system emulsion opal glass needs the process carrying out emulsifying at pristine glass 700-900 DEG C, and heat treatment time is 2-6 hour, this process will consume a lot of energy and resource, is also unfavorable for industrial mass consecutive production.
Visible, existing emulsion opal glass is harmful to environment and human health, and product opacity is low and unstable, and some needs second heat treatment (general 4-8 hour), not only consumes mass energy and is unfavorable for consecutive production.The resistance toheat of product is poor, is difficult to be applicable to the modern household electrical appliances such as microwave oven, baking box.
