THE FABRICATION METHOD OF NANO-SILICA COATED WITH THE ORGANIC CATALYST TO REMOVAL OF ALDEHYDE GAS

摘要

PURPOSE: A method for manufacturing organic catalyst-nano silica for eliminating aldehyde gas is provided to uniformly coat organic catalyst based on a synthetic reaction in nano-sol and to reduce the loss of solid materials. CONSTITUTION: Nano-sol is prepared by mixing and stirring 40-60 parts by weight of tetraethyl orthosilicate, 10-40 parts by weight of ammonia solution, and 40-80 parts by weight of water based on 1000 parts by weight of ethanol solution and by generating nanoscale silica spheres. 10-40 parts by weight of organic catalyst are molten in 1000 parts by weight of the nano-sol and are reacted for 100 to 200 minutes to obtain organic catalyst and nanosilica dispersed nano-sol. The nanosilica dispersed nano-sol is maintained at a temperature of 60 to 80 degrees Celsius. The solution is volatized to obtain solid materials based on organic catalyst-nanosilica.
