| Use | This product can be used with acrylic acid and esters, acrolein, acrylonitrile, acrylamide, methacrylonitrile, vinyl chloride, styrene and many other monomers are copolymerized, and the obtained products can be used to treat fibers to improve the water resistance, solvent resistance, wrinkle resistance and water resistance of fibers. It is also used to manufacture thermosetting coatings and synthetic rubbers with excellent performance, it is used as an additive for lubricating oil, etc. In the adhesive, the adhesive strength can be improved by copolymerizing with a vinyl monomer. In terms of paper processing, acrylic emulsion for coating can improve its water resistance and strength. The reactive diluent and crosslinking agent used in radiation curing system can also be used as resin crosslinking agent, plastic, rubber modifier wood varnish, printing Inks and Adhesives are mainly used in the manufacture of thermosetting acrylic coatings, photo-curable acrylic coatings, photosensitive coatings, adhesives, textile treatment agents, paper processing, water quality stabilizers and polymer materials. With the use of less, but can significantly improve the performance of the product characteristics |
| production method | addition reaction of acrylic acid with ethylene oxide in the presence of catalyst and polymerization inhibitor, the crude product of acrylic acid -2-hydroxy ethyl ester is produced, and the raw material consumption quota of the finished product is obtained by degassing and distillation: acrylic acid 710kg/t, ethylene oxide 485kg/t. |
