Description
Technical field
The present invention relates to glass coating technical field, particularly relate to a kind of antifog transparent heat-insulated nano-glass coating of environmental protection and preparation method thereof.
Background technology
Along with society is to the energy-conservation continuous attention with environmental requirement, the common requirements of people can be become at the heat-protecting glass that different places uses, and existing heat-protecting glass exists the drawback that performance imperfection, complex process or cost are high.Nano antimony tin oxide (ATO) has good visible light permeability and infrared barrier, is a kind of preferably heat-barrier material.Nano antimony tin oxide is joined in coating and make the method for transparent heat insulating dope and can effectively solve the heat-insulating problem of glass, compared with similar products, there is the advantage that technique is simple, with low cost, there is high using value and wide market prospect.First " preparation of transparent heat-insulated nano-glass coating and performance study " literary composition have studied nano antimony tin oxide dispersive property in water, has investigated pH value, dispersant and consumption, different dispersion means and the technological parameter impact on the dispersion stabilization of nano antimony tin oxide thereof.Result shows, nano antimony tin oxide isoelectric point, IP in water is at pH=4.27, and during system meta-alkalescence, dispersion stabilization is significantly increased.The optimum dispersant of dispersion is a kind of anionic macromolecule dispersing agent, and consumption is about the 2% of ATO particle weight.This article has also investigated the impact on dispersion stabilization of different process for dispersing and process conditions thereof, for single dispersion means, ball milling dispersion and high speed dispersion effect are better than ultrasonic disperse, by secondary ball milling method, ATO is disperseed, the grinding distribution time can be shortened while obtaining with a ball-milling method same particle sizes.Within the particle diameter of the nano antimony tin oxide aqueous dispersion obtained with above-mentioned optimum formula and dispersing technology is distributed in 100nm.This article also mixes with aqueous polyurethane mutually with the aqueous dispersion of nano antimony tin oxide, adds a certain amount of thickening agent and other auxiliary agent, has prepared transparent heat insulating dope of good performance.Being tested this transparent heat insulating dope by homemade effect of heat insulation test device, result shows, this coating has good effect of heat insulation.Under the conditions of pigment is 1/5, after system reaches equilibrium temperature, the box chamber air temperature difference of sample and blank glass reaches 6 ° of C, and the discussion to insulating mechanism shows: effect of heat insulation is played a role jointly by absorbing and reflect two parts.This transparent heat insulating dope has good spectral selection, has high permeability in visible region and can effectively intercept the heat radiation in infrared light district.Pigment is that the light transmittance of the coating entirety of 1/5 maintains more than 65%, and near infrared region (900～2500nm), light transmittance drops to again about 40%, and coating has obvious spectral selection.By showing the scanning electron microscope analysis of film, nano antimony tin oxide particle major part particle diameter in film smooths less than 100nm, even particle size distribution, film.
But film all has certain water absorption and water penetration, easily causing wrinkling coming off after water suction, nano-indium stannum oxide is meeting degeneration under the effect of long-term water, affects effect of heat insulation, needs to improve resistance to water.
Additionally glass coating film there is also some problems needs to solve, the such as performance such as thermostability, wearability, static electricity resistance, toughness, antibiotic property, resistance to acids and bases, transparency, scratch resistance, environmental-protecting performance, anti-radiation, Anti-tarnishing, anti-flammability, ultra-violet resistance has different demands under different occasions, current coating still can not meet the needs of all environment, require further improvement performance, to meet the needs of production.
