Description

It is a kind of for the single-component water-based polyurethane fire retardant, anticorrosive coating of wide variety of substrates and preparation Method
Technical field
The present invention relates to a kind of single-component water-based polyurethane fire retardant, anticorrosive coating and preparation method for wide variety of substrates, category In anticorrosion field.
Background technology
The whole world is every year because of the volatile organic chemistry material about 500-600 ten thousand discharged using solvent based coating and into air Ton, said from environmentally friendly and saving petroleum resources angles, the Water-borne modification of coating is a developing direction.
In recent years, for destructions and pollution of the VOC to environment, various countries have been made to pay attention to closely to VOC harmfulness and numerous and confused Various regulations are formulated to limit VOC emission.U.S. Los Angeles has just promulgated famous " 66 regulation " early in 1966, and this is coating First regulation of solvent composition is controlled in industry.Atmospheric pollution law (Clean Air Act) that the U.S. passes through nineteen ninety and AIM (Architectural and Industrial Maintenance Coatings Rules) regulations of issue in 1998 The VOC emission of industrial coating is limited to the 340g/L being down to from the 420g/L of nineteen ninety 1993, continues to be down to 250g/ within 2000 L.The relevant furniture industry that Europe is formulated reduces VOC Directive99/B/CE legislations, it is desirable to which, by 2007, all enterprises are molten The permission consumption of agent is about original 1/4.Under increasingly strict legislations of environmental protection drives, many major companies in Europe Spare no high price to carry out development environment ecad coating technology, water paint stands in the breach, the maximum woodwork coating production in European market The huge fund of business BecnerAcroha inputs year sales volume 7% is directed to development environment ecad coating.In the U.S., the maximum water of dosage Property woodcare paint be water-based polyurethane, U.S.'s polyurethane aqueous dispersion body resin consumptions in 1998 are 1.8 ten thousand tons, wherein larger portion Divide with woodcare paint.At present, aqueous industrial woodcare paint has been obtained for certain application in the U.S., such as on furniture, floor Industry.In Europe, due to being influenceed by legislation and technical elements factor, such as rate of drying and heat resistanceheat resistant stickiness, at the same also by The influence of price, operating expenses and new technology spread etc. factor, progress are relatively slow.With aqueous industrial woodcare paint phase Than the development speed of aqueous heavy anti-corrosion paint is also slower.At present, the more of research is aqueous inorganic zinc silicate antirust paint, water Property acrylic acid, water-base epoxy, aqueous polyurethane etc..
With the continuous renewal of development and the environmental requirement of technology, the dosage of solvent based coating will decline, and water-based painting Material, solventless coatings, powdery paints etc. will rise year by year.In terms of water paint, aqueous polyurethane coating is good due to its Antiseptic property, widely using field, simultaneously as it can significantly reduce the pollution to environment in the production and use process Harm with to the producer and user, receives much concern.
The content of the invention
It is an object of the present invention to provide a kind of single-component water-based polyurethane fire retardant, anticorrosive coating for wide variety of substrates, its group Aqueous polyurethane in is a kind of polyaminoester emulsion for being dispersed in water swelling, and emulsion particle diameter is mostly 0.01-0.5 μm, than The particle diameter of acrylic emulsions is smaller.The characteristics of product researched and developed of the present invention water-based polyurethane flame-proof anticorrosive paint is single group Point, and without free isocyanates, it is nontoxic;Room temperature film-forming, it is not necessary to add coalescents, therefore can have the volatility in system Machine compound (VOC) content is reduced to 0, has the advantages that safe to use, non-environmental-pollution.Aqueous polyurethane also has levelability It is good, strong covering power, adhesion-tight, the features such as coating is cold-resistant, heat-resisting.Although aqueous polyurethane dispersion its relative molecular mass is very It is high.But it has that viscosity is relatively low, easy processing, it is easy for construction the features such as.By aqueous polyurethane fire retardant, anticorrosive coating system of the present invention Into after dried coating film, its mechanicalness can match in excellence or beauty with solvent borne polyurethane coating, have prominent hardness, wearability and chemically-resistant Moral character.
