Abstract
Official abstract text for this publication.
A method for preparing an organic-inorganic hybrid porous insulation coating composition includes steps of: adding sepiolite nanoparticles that have been surface-treated with silane or dimethyl ammonium chloride to a thermal-resistant resin solution; and stirring the thermal-resistant resolution solution containing the sepiolite nanoparticles at 3600 rpm or more for 30 minutes or more. The thermal-resistant resin solution includes at least one thermal-resistant resin selected from the group consisting of polyamide-imide, polyester, polyester-imide and polyamic acid.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for preparing an organic-inorganic hybrid porous insulation coating composition comprising steps of: adding sepiolite nanoparticles that have been surface-treated with silane or dimethyl ammonium chloride to a thermal-resistant resin solution; and stirring the thermal-resistant resolution solution containing the sepiolite nanoparticles at 3600 rpm or more for 30 minutes or more, wherein the thermal-resistant resin solution includes at least one thermal-resistant resin selected from the group consisting of polyamide-imide, polyester, polyester-imide and polyamic acid, and the sepiolite nanoparticles are added in a content of 0.1 to 5 wt %, based on a total weight of a solid included in the solution. 2. The method of claim 1 , wherein the sepiolite nanoparticle has a specific surface area of 230 to 380 m 2 /g. 3. The method of claim 1 , wherein the sepiolite nanoparticle has a size of 50 to 500 nm. 4. The method of claim 1 , wherein the thermal-resistant resin solution includes the thermal-resistant resin in a content of 15 to 45 wt %, based on a total weight of the thermal-resistant resin solution. 5. The method of claim 1 , wherein the thermal-resistant resin solution includes at least one organic solvent selected from the group consisting of N-methylpyrrolidone (NMP), dimethyl formamide (DMF), dimethylacetamide (DMAc), cellusolves, glycols, and ketones.
