HOUSING INDUSTRY COATING MATERIAL HAVING MALODOR ADSORPTION CAPABILITY AND ULTRAVIOLET RAY RADIATION CAPABILITY

摘要

PPROBLEM TO BE SOLVED: To provide a coating material for housing industry which has the capability of adsorbing formaldehyde and a malodorous substance and capability of ultraviolet ray radiation, at a high level. PSOLUTION: A charcoal micropowder roasted at about 700C, having a specific surface area of at least about 200 mSP2/SP/g, and pulverized to 50 or smaller is mixed with a micropowder obtained by grinding graphite silica stone to a size of 50 or lower, in a ratio of 9/1. Into the resultant mixture, strong alkaline electrolyzed water is mixed, and then a 10% specific polyvinyl alcohol resin solution is mixed. The rough standard of the above mixing ratio is 22 litter of strong alkaline electrolyzed water, 9 kg of a charcoal micropowder, 15 kg of a 10% specific polyvinyl alcohol resin solution, and 1 kg of graphite silica stone. Thus is obtained the housing industry coating material. PCOPYRIGHT: (C)2009,JPO&INPIT
