Abstract
The invention discloses a preparation method for high performance acrylic waterborne resin. The method is characterized by including: 1) grinding solid acrylic resin into fine powder able to pass through a 120-mesh sieve; 2) under mechanical stirring, adding water, ethanol, ethylene glycol butyl ether, ammonia water and a defoaming agent into a stainless steel container in order; 3) under mechanical stirring, adding solid acrylic powder resin slowly and making it fully dispersed into transparent and viscous liquid resin, and conducting packaging with a vat to make the product used for paint making. The preparation method provided by the invention has the advantages of simple process, good production stability, effectively shortened reaction time, stable product performance, and good economical efficiency. The acrylic waterborne resin prepared by the method is comparable with equal oil resin from the aspects of performance, appearance and cost, so that replacing oil paint by water paint becomes possible, and the safety and environmental problems of oily paint are effectively solved.
Description
Technical field
The invention belongs to chemical technology field, be specifically related to a kind of preparation method of high-performance acrylic acid water-base resin.
Background technology
The features such as it is high that acrylic resin has gloss, and good mechanical property is weather-proof are the important raw and processed materials of manufacturing paint.Owing to containing a large amount of organic solvents in paint, contain the hazardous and noxious substances such as benzene, and also inflammable, be listed in hazardous chemical.Therefore paint has danger, contaminate environment, three large shortcomings are detrimental to health.Paint Water-borne modification is the important channel that solves three large shortcomings.Paint Water-borne modification whole world coating circle scientific research personnel has struggled decades for it, still has the contradiction of cost and performance at present, is not well solved, and therefore cannot large-scale popularization use.
Acrylic acid aqueous paint, main employing is added to the water acrylic resin at present, and under the help and mechanical stirring of emulsifying agent, make ACRYLIC EMULSION, for the manufacture of acrylic latex coating, water-miscible paint gloss too low (conventionally below the 60%) poor performance that the emulsion that the method makes is manufactured, painting process can not be for master grind.Bring a lot of difficulties to painting process, use and be restricted.At present, mainly for the manufacture of wall paint in building, Decoration Industry.Vinylformic acid water dispersed resin is to carry high performance better method, but water-dispersion technique is the key that determines resin quality.Water-dispersion technique in industry is also unsatisfactory at present, and water dispersed resin quality does not improve.Therefore acrylic acid aqueous paint performance is compared and is had huge spread with oil-base paint.Therefore, how producing high-performance acrylic acid water-base resin high-quality, that high-performance is identical with oil-base paint, is the problem of scientific and technical personnel's concerted effort struggle in industry.
Summary of the invention
For the problem existing in background technology, the invention provides a kind of preparation method of high-performance acrylic acid water-base resin, the acrylic acid aqueous resin property that adopts preparation method of the present invention to make approaches equal oil-base paint, cost is also lower than equal oleoresin, has solved safety, environmental protection, Cost Problems that oil-base paint exists.
The technical solution used in the present invention is:
A preparation method for high-performance acrylic acid water-base resin, is characterized in that:
1) solid propenoic acid resin is pulverized and is the smalls that 120 eye mesh screens pass through, standby;
2), in stainless steel vessel, under mechanical stirring, be sequentially added into:
Water: 5%
Ethanol: 28%
Butyl glycol ether: 11%
Ammoniacal liquor: 5%
Defoamer: 1%;
3) under mechanical stirring, slowly add solid propenoic acid powdex 50%, make it fully disperse to cause transparent thick resin liquid, with drum, pack, for painting, use.
Said components content is quality percentage composition.
Beneficial effect of the present invention is:
1) preparation technology's flow process of the present invention is simple, and production stability is good, and has effectively shortened the reaction times, and product performance are stable, good economy performance.
2) no matter the acrylic acid aqueous resin that this technique makes is that performance, outward appearance, cost all can be compared U.S. with equal oleoresin, and making water-miscible paint substitute oil-base paint becomes possibility, efficiently solves safety, environmental issue that oil-base paint exists.
Embodiment
Below in conjunction with embodiment, to further instruction of the present invention, in embodiment, be quality percentage composition, but the present invention is not limited thereto.
