PREPARATION METHOD OF AQUEOUS PAINT FOR BUILDING INSIDE COATING AGENT WHICH USES YELLOW SOIL AND OYSTER SHELL, EMITS FAR INFRARED RAY AND ABSORBS ELECTROMAGNETIC WAVE

摘要

PURPOSE: A method for preparing an aqueous paint using yellow soil and oyster shell is provided, which paint is used to coat the inside of the building for shielding the toxicity of cement by emitting the far infrared ray and shielding the electromagnetic wave. CONSTITUTION: The method comprises the steps of pulverizing yellow soil containing SiO2; pulverizing zeolite, hell stone, sericite and oyster shell to the size of 10 mm or less; indirectly calcining hell stone and sericite at 750-850 deg.C, zeolite at 650-700 deg.C and oyster shell at 450-500 deg.C to remove the impurities; repulverizing the calcined one; boiling gingko leaves, pine needles and overcup oak leaves in about 35% salt water at 80-90 deg.C for 20-30 min; drying and pulverizing the boiled one to the size of 325 mesh; drying and pulverizing rice hulls to the size of 325 mesh; dissolving PVA into water of 65-70 deg.C to obtain an adhesive; and mixing 10-15 wt% of the zeolite; 10-15 wt% of the hell stone; 20-30 wt% of the yellow soil; 10-15 wt% of the sericite; 5-7 wt% of the rice hulls; 5-7 wt% of the pine needles; 5-7 wt% of the gingko leaves; 5-7 wt% of the overcup oak leaves; 10-15 wt% of the oyster shell; and 10-20 wt% of the adhesive solution.
