TWO COMPONENT TYPE POLYURETHANE WATERPROOFING STUFF HAVING ENVIRONMENTAL FRIENDLINESS, IMPROVED ELASTICITY AND ULTIMATE TENSILE STRENGTH

摘要

The present invention is elastic and as a tensile strength of an improved two-component environmental-friendly polyurethane waterproof materials, the present invention is a first polyol having an aromatic polyisocyanate compound and two or more hydroxyl groups per one molecule having at least two isocyanates per molecule the subject matter consisting of a compound that contains the urethane prepolymer is reacted with at least two terminal isocyanate groups to produce; In a second polyol compound having two or more hydroxyl groups per molecule, the polyfunctional chain extender, two-component polyurethane waterproof materials consisting of a curing agent which contains the catalyst and a plasticizer, wherein the curing agent is first based on 100 parts by weight of the urethane prepolymer 2 and 15-110 parts by weight of the polyol compound; Water repellency, of the compound having an aromatic ring is present during the distillation of benzene, toluene, xylene and the like for the elastic and tensile strength, improved distillation million or more C15 compounds and the broken double bond in the compound by hydrogenation or reaction with a Cyclic structure compound 10 to 150 parts by weight; Polyfunctional chain extender of 2 to 20 parts by weight; 1-15 parts by weight of the catalyst; It characterized in that the plasticizer comprises 3 to 40 parts by weight. ; Polyurethane, waterproofing, subject, hardeners
