ACRYLIC MODIFIED POLYESTER RESIN CONTAINED PHOSPHATE HAVING HIGH MOISTURE RESISTANCE AND RESIN COMPOSITION FOR COLOR STEEL SHEET USING THEREOF

摘要

The present invention relates to a humidity resistance superior phosphorus-containing the acrylic-modified polyester resin, a method of manufacturing the same, and PCM (Pre Metal Coated) color steel sheet using the same coating material.; The present invention is a polyhydric acid as an aromatic acid, an aliphatic acid, and the use of raw materials of the cycloaliphatic acid ratio titration and polyhydric by introducing an alcohol monomer of the linear structure of the composition of the alcohol material in durability and corrosion resistance and workability securing polyester resin Preparation and acid, of the polybasic acid component, an alicyclic, after the primary addition polymerization of acrylic monomer to the polyester resin-containing solution, by preparing the phosphorus-containing the acrylic-modified polyester resin and a phosphoric acid monomer second addition polymerization internal by the formation of a graft bond between carbon double bond between the acrylic monomers remaining in, the adhesive force between the moisture in chamber and a hydrophobic coating provides improved acrylic-modified polyester resin. Further, the phosphorus-containing the acrylic-modified polyester resin of the present invention, because of the in chamber humidity resistance and a certain time the adhesion of the hydrophobic coating to improve the physical properties after the same time preserved the physical properties of the polyester resins useful in the PCM color steel sheet coating They can be used.
