Abstract: Example embodiments include a battery insulation sheet having a structure in which a first substrate, an aerogel layer, and a second substrate are laminated, wherein opposite surfaces of the aerogel layer is in contact with the first substrate or the second substrate adjacent thereto. Example embodiments also include a method of manufacturing a battery insulation sheet, and a battery module including the battery insulation sheet.

Abstract: The present invention relates to an aerogel composite and a preparation method thereof. The preparation method of the aerogel composite of the present invention comprises the following steps; preparing a hydrophobic gel (step 1); dispersing fiber in a solvent to prepare a solution (step 2); adding the hydrophobic gel above in the solution of step 2 and stirring the mixture to prepare a fiber and hydrophobic gel mixed solution (step 3); separating floc from the mixed solution of step 3 (step 4); and drying the floc (step 5). According to the preparation method of the aerogel composite of the present invention, a high performance aerogel composite having various shapes can be prepared.

Abstract: A binder composition for spray used for interior materials is disclosed to provide glass wool or rock wool with an adhesive force by simultaneously spraying two solutions onto the glass wool or rock wool so that the glass wool or rock wool is adhered to steel or concrete to enhance effects of heat insulation and sound insulation. The binder composition contains a first solution of 200 to 400 parts by weight consisting of polyvinyl alcohol, preservative, antifoaming agent and purified water, and a second solution of 100 parts by weight consisting of boric acid, basic compound, glycerin and purified water.
