WATERPROOF AND ANTI-CORROSIVENESS COATING COMPOSITION HAVING CHEMICAL RESISTANCE, WEATHER-RESISTANCE, ADHESION INCLUDING URETHANE MODIFIED EPOXY RESIN PREPARED BY POLYHYDRIC ALCOHOLS AND MANUFACTURING METHOD BY USING SAME

摘要

The present invention may includes: a main ingredient part which contains 45-55 wt% of urethane denatured epoxy resin manufactured by using polyol, 5-10 wt% of reactive diluents, 3-10 wt% of acrylic monomer, 30-40 wt% of extender pigments, 5-10 wt% of ceramic powder, 1-3 wt% of inorganic pigments, and 1-3 wt% of additives; and a hardening agent part which includes at least one between cyclic polyamide and aliphatic polyamide, wherein the main ingredient part and the hardening agent part are mixed in the weight ratio of 100 : 10-20, the urethane denatured epoxy resin is manufactured by manufacturing epoxy resin which contains hydroxyl groups (-OH) by adding epoxy compounds and catalysts to the mixed solution of polyol and ether compounds; and inducing isocyanate by adding isocyanate compounds to hydroxyl groups (-OH) on the epoxy resin.;COPYRIGHT KIPO 2016
