HEAT ISOLATING COATING COMPOUNDS AND THE MANUFACTURING METHODS, HEAT ISOLATING WATERPROOFING CONSTRUCTION METHOD USING THE HEAT ISOLATING COATING COMPOUNDS

摘要

PURPOSE: A heat-isolating top-coating composition is provided not to generate material harmful for workers, to have excellent heat isolation, durability, adhesion, etc, and to have fast drying rate, thereby having excellent constructability. CONSTITUTION: A heat-isolating top-coating composition comprises: a firs composition comprising 20-40 wt% of polymethylmethacrylate resin, 1-10 wt% of polyol, 1-15 wt% of plasticizer, 10-20 wt% of calcium carbonate, 10-20 wt% of heat-blocking pigment, 1-5 wt% of metallic inorganic pigment for heat-blocking, 10-20 wt% of hollow pigment, 0.2-2 wt% of dispersant, 0.2-2 wt% color-separation preventing agent, 0.2-2 wt% of antifoaming agent, and 0.2-2 wt% of leveling agent, for providing heat-isolation; a second composition comprising 70-85 wt% of polyol, 0.1-1 wt% of 1,3-butylene glycol, 14-24 wt% of isocyanate, and 0.5-6 wt% of xylene; and a benzoyl peroxide as a hardener.
