Abstract
The invention relates to the field of paints, particularly a water-based alkyd environment-friendly paint. The paint is characterized by comprising the following components in parts by weight: 30-100 parts of water-based alkyd resin, 4-15 parts of dimethylolpropionic acid, 2-3 parts of butyl ether, 2-3 parts of neutralizer and 50-200 parts of water. The water-based alkyd environment-friendly paint has the advantages of wide raw material sources, low price, high water solubility and low preparation cost, and has wide application prospects.
Description
Technical field
The present invention relates to paint field, be specifically related to a kind of water alcohol acid environmental protection paint.
Background technology
Synolac is a kind of important coating resin, monomer whose source is abundant, price is low, wide in variety, formula change large, facilitate chemical modification and performance good; Synolac both can be prepared single component self-drying paint, also can prepare two-pack from dry (as polyurethane paint) or hot curing varnish (as amine baking varnish).Therefore since Synolac exploitation, Synolac occupies an important position at coatings industry always.But the same with other solvent based coatings, solvent-borne type alkydpaints contains a large amount of solvent (>40%), therefore producing, serious harm atmospheric environment in construction process
And operator ' s health.In recent years, the environmental regulation increasingly stringent of countries in the world, traditional solvent based coating is subject to increasing challenge, and the Water-borne modification of coating, high solid trend are more and more distinct.
It is solvent that aqueous alkide resin be take water and a small amount of solubility promoter, organic solvent amount greatly reduces, therefore lower by the VOC (volatile organic matter) of the coating system of its preparation, the developing direction that meets modern coatings Industrial Green, environmental protection, industrial community, research institution have dropped into a large amount of human and material resources and have researched and developed.Synolac is a kind of that coating is maximum by output in synthetic resins, purposes is the widest.It can prepare self-drying paint and baking finish, house paint and industrial paint, and varnish and colored paint.The fat type of Synolac and oil content have decisive influence to its application.
Aqueous alkide resin has been inherited the advantage of Synolac and can have been obtained good weathering resistance, water tolerance, erosion resistance, sticking power, drying property etc. by modification.The development and application of Water-borne Alkyd Coatings, has not only reduced the quantity discharged of VOC, be conducive to environment protection, and comprehensive cost is lower, so Water-borne Alkyd Coatings is promising.The research of water soluble alkyd resin at present mainly concentrates on: the working viscosity that reduces coating, eliminate the dilution peak that water soluble alkyd resin occurs in water dilution, use environment amenable cosolvent, further strengthen the erosion resistance of thin coating film, improve outward appearance and reduce costs, exploitation has the water soluble alkyd resin coating of features.Coatings enterprises is stepped into today of Chinese market one after another abroad, and the high-performance coating that only has Devoting Major Efforts To Developing to have independent intellectual property right just can be caught up with and surpassed advanced country in the world.
As 201110143908.4, the patent of invention that denomination of invention is " a kind of take the coating that aqueous alkide resin is major ingredient ", a kind of coating that aqueous alkide resin is major ingredient of take is provided, it is characterized in that its formula is: by weight percentage, major ingredient: aqueous alkide resin 50-55%, thinner: rosin 40-50%, additive: washing powder 5-10%., the aqueous alkide resin of this patent is water-soluble still undesirable.
Summary of the invention
