Abstract

The invention provides a toughened glass heat-insulation transparent high-temperature dielectric paste and a manufacturing method thereof. The manufacturing method thereof comprises steps of: putting a medium, a function material and an adhesive in a container, completely and evenly mixing, grinding and passing inspection to obtain the toughened glass heat-insulation transparent high-temperature dielectric paste, wherein the medium is prepared from inorganic materials such as silica, bismuth oxide, boric acid, titanium dioxide, alumina, zinc oxide and the like. The inorganic materials are adopted as the medium, and the curing temperature is the tempering temperature of glass, therefore, the invention has strong adhesion and hardness close to that of the glass. The invention has superiority to the traditional product in water resisting property, hardness, temperature difference resisting property, heat resistance, mar-resistance, acid and alkali resistance, and the like.

Description

Toughened glass heat-insulation transparent high-temperature dielectric paste and method of manufacture thereof

Technical field

The present invention belongs to the thermal insulating coating that is applied to the glass technology field.Be specifically related to a kind of toughened glass heat-insulation transparent high-temperature dielectric paste and method of manufacture thereof.

Background technology

Be applied to heat-insulated transparent coating on glass at present and be organic cpds such as lipids as sticker, its solidification value is below 200 ℃, and shortcoming is that sticking power is poor, can wipe off with hard thing, and mechanical wear-resisting wiping property, weathering resistance are also poor.And, come off along with lipid (organism) receives long-term radiation easy ageing such as ultraviolet ray, thereby lose its heat insulation effect.To this deficiency; The present invention with inorganic materials as linking agent (dielectric); Solidification value is the tempering temperature of glass, promptly with glass tempering and sintering curing interpenetrates together, strong adhesion simultaneously; Hardness and glass hard (HRC65 are close, and its water tolerance, hardness, temperature difference resistance, thermotolerance, mar-resistance, resistance to acids and bases etc. all have meliority than present product.

Summary of the invention

To the deficiency of currently available products, the object of the present invention is to provide a kind of toughened glass heat-insulation transparent high-temperature dielectric paste and method of manufacture thereof.

For reaching goal of the invention, toughened glass heat-insulation transparent high-temperature dielectric paste provided by the invention adopts following technical scheme:

(1), the preparation of dielectric (binding agent)

The one-tenth of dielectric has been grouped into: silicon-dioxide (0～30%), bismuth oxide (0～20%), boric acid (0～30%), titanium oxide (0～3%), aluminum oxide (0～0.2%), zinc oxide (0～10%), magnesiumcarbonate (0～2%), lime carbonate (0～1%), SODIUMNITRATE (0～3%), saltpetre (0～1%), Quilonum Retard (0～2%), weisspiessglanz (0～0.1%), ZIRCONIUM DIOXIDE 99.5 (0～2%) etc.

The preparation method of dielectric is:

It is an amount of to get silicon-dioxide, bismuth oxide, boric acid, titanium oxide, aluminum oxide, zinc oxide, magnesiumcarbonate, lime carbonate, SODIUMNITRATE, saltpetre, Quilonum Retard, weisspiessglanz, ZIRCONIUM DIOXIDE 99.5 etc.; Mix according to a certain percentage, the electric furnace of putting the about 1200-1400 of furnace temperature ℃ into is incubated several minutes, under molten state, takes out and quenches; Form the glass medium crystal; Xln was ground 48 hours, and taking-up is sieved, and gets its fineness and reaches the medium powder below the 500nm.

(2), functional materials

The composition of functional materials (transparent insulate material) has: nano ATO powder (tin-antimony oxide), nano-ITO powder (indium tin oxide), conductive powder body.

(3), the preparation of toughened glass heat-insulation transparent high-temperature dielectric paste

Dielectric (45%～70%), functional materials (5～16%), tackiness agent (20～40%) (staple is Terpineol 350 (98%～100%)) are put into container; Thorough mixing is even; Grind, being up to the standards promptly obtains toughened glass heat-insulation transparent high-temperature dielectric paste, slurry fineness :≤500nm.

With respect to the existing thermal insulating coating that is applied to glass art; Toughened glass heat-insulation transparent high-temperature dielectric paste provided by the invention with inorganic materials as dielectric (binding agent); Be widely used in transparent heat-insulated, the insulation and energy-conservation of building glass, vehicle glass, train glass, electronic glass etc.; Glass is passed in the infrared rays and the ultraviolet ray that can effectively intercept in the sunshine, and visible light transmissivity can reach more than 80%, and can prevent that indoor heat energy from arriving outdoor through glass; Keep room temp, meet the target that country advocates energy-conserving and environment-protective.This product core advantage is that wear-resisting wiping property and surface hardness and toughened glass surface are very approaching, but on the permanent attachment glass surface, more can reach the final purpose of transparent heat-insulating energy-saving.

Embodiment

As shown in Figure 1, it is an amount of to get silicon-dioxide, bismuth oxide, boric acid, titanium oxide, aluminum oxide, zinc oxide, magnesiumcarbonate, lime carbonate, SODIUMNITRATE, saltpetre, Quilonum Retard, weisspiessglanz, ZIRCONIUM DIOXIDE 99.5 etc., mixes according to a certain percentage; The electric furnace of putting the about 1200-1400 of furnace temperature ℃ into is incubated several minutes; Under molten state, take out and quench, form the glass medium crystal, xln was ground 48 hours; Taking-up is sieved, and gets its fineness and reaches the medium powder below the 500nm.
