PREPARING METHOD OF SALIFIED SOL FOR COATING INTERIOR MATERIALS

摘要

A method for preparing a chloride sol for coating an interior material is provided to prevent the release of volatile organic compounds from an interior material such as a door, etc. by coating it with the chloride sol. A method for preparing a chloride sol comprises the steps of (S10) mixing 8-12 parts by weight of sericite, 1.5-2.5 parts by weight of sodium chloride and 100 parts by weight of water and pulverizing the mixture to a nanosize; (S20) leaving the mixture alone to separate it into a precipitant and a supernatant and filtering it to obtain a sericite aqueous solution of a supernatant; (S30) mixing 100 parts by weight of the sericite aqueous solution, 15-25 parts by weight of hydrogen peroxide and 20-25 parts by weight of methyl alcohol with stirring; (S40) increasing the temperature constantly from 100 deg.C to 350 deg.C for 30 min and stirring it to firstly swell it; (S50) mixing the firstly swollen composition with hydrogen peroxide with stirring to secondly swell it; and (S60) rapidly cooling the secondly swollen composition to a room temperature.
