Description
Technical field
The present invention relates to painting technical field, be specifically related to a kind of aqueous environment protection coating for glass article surface and preparation method thereof
Technical background
Ceramic material produces people and has a wide range of applications in life, except the use on feeder, ornament, science, technology development in also play an important role. Production and processing pottery and high temperature gloss firing (envelope glaze) need to consume the substantial amounts of energy, from little to several ton greatly to the raw mill of up to a hundred tons to the fineness of regulation, kiln high-temperature firing more than 1,000 degree, is then polished under press, both directly and indirectly consumes a large amount of coal. It is packaged as example with Liquor, according to statistics, the yield of national Chinese liquor in 2010 is 8,910,000 kilolitres (amounting to about 10,000,000,000 bottles), wherein 28% is ceramic wine bottle, producing these ceramic wine bottles needs energy input to amount to standard coal more than 2,800,000 tons, and use after ceramic wine bottle cannot recycling, cause huge burden to environment.
But then, China has long Ceramics Culture tradition, in very long historical floods, the Chinese ancestors of industry and intelligence cut the earth into gold, aesthetic appeal unique in oriental cultural is penetrated in porcelain making art, it had both comprised the numerous people pursuit to life Sino-U.S., again using unique glamour as Sinitic carrier. This major reason that also ceramic material is used widely in the modern life just.
Therefore, in order to people's pursuit for quality of the life can be met, accomplish " the low-carbon (LC) life " of energy-saving and emission-reduction again, so people select there is vial outer surface sprayed coating, outer surface at glass forms the effect of envelope glaze, it is thus possible to substitute ceramic high temperature colored glaze bottle. This new product and application thereof have the plurality of advantages such as low-carbon (LC), safety and environmental protection. Through estimation comprehensively; whole low temperature envelope glaze type glass wine bottle energy consumption from ore processing to final products is only the 1/10 of pottery envelope glaze bottle energy consumption; the substantial amounts of energy can be saved; and seal glaze glass wine bottle and can reclaim reprocessing, energy-saving and emission-reduction and environmental conservation are had and has very great significance.
Owing to current glass coating is mostly solvent based coating, benzene,toluene,xylene to human body and bad environmental etc. during application, need to be used containing benzene solvent; It addition, the adhesive strength of some coating is low, the adhesive force of various glass material products is less, so the application of inapplicable glass material product.
