Composition for air-drying polyurethane modified vinylester resin and method of preparing the same

摘要

The present invention for the purpose of providing air drying properties of the polyurethane-modified vinyl ester resin composition and a production method to be, specifically, the high corrosion resistance of the vinyl ester resin, high strength, toughness and outstanding advantages High efficiency of the polyurethane resin, a low profile as well as the air within the drinking water and having all of the advantages in that the contact part is made of hardened resin FRP, provides a resin suitable for the plant to deal with strong acid or alkali. More particularly, the air gun is a polyurethane-modified vinyl ester resin composition consisting of a copolymer of a polyurethane resin and a vinyl ester resin composition function is given to provide a method of manufacturing the same. Air drying the polyurethane-modified vinyl ester resin composition according to the present invention as the component (a) air-gun and 10 to 50 parts by weight of the polyurethane resin is imparted composition, (b) component is a vinyl ester resin and 10 to 50 parts by weight of the 20 to 50 parts by weight of a reactive diluent made jimyeo if necessary, 0.1 to 5 parts by weight of a curing accelerator, 0.01 to 0.1 parts by weight of a curing co-promoter, a polymerization inhibitor 0.01 to 0.1 parts by weight consists in blending. Air drying the polyurethane-modified vinyl ester resin composition according to the present invention having a high corrosion resistance, a vinyl ester resin, high strength, toughness, outstanding benefits and a polyurethane having an elongation castle, the part in contact with air, while at the same time meet the advantages of low shrinkage also shows an effect to provide a resin composite having improved physical properties more suitable for drinking water in FRP, equipment to deal with a strong acid or alkaline curing so formed has the advantage.
