COATING MATERIAL, COATED BODY, RESIN COMPOSITION FOR COATING INNER SURFACE OF PIPE JOINT AND PIPE JOINT

摘要

PROBLEM TO BE SOLVED: To obtain a resin composition that has flexibility even in the cold district at 0-30 deg.C, particularly for coating the inner face of pipe joints having shock resistance at a lower temperature by using a specific methyl methacrylate- butadiene-styrene terpolymer and a chlorinated polyethylene resin. SOLUTION: The objective coating material comprises a vinyl chloride resin, methyl (meth)acrylate-rubber polymer-aromatic vinyl terpolymer and a chlorinated polyethylene resin. In a preferred embodiment, a methyl methacrylate- butadiene-styrene terpolymer is used as the copolymer component. A preferred polymer composition comprises 100 pts.wt. of vinyl chloride resin, 5-30 pts.wt. of a methyl methacrylate-butadiene-styrene terpolymer and 5-30 pts.wt. of chlorinated polyethylene resin.
