METHOD FOR PREPARING ENVIRONMENTALLY-FRIENDLY INORGANIC RESIN COMPOSITION AND COMPOSITION PREPARED THEREBY

WIPO Patent Application WO/2014/007486

A1

Disclosed are a method for preparing an environmentally-friendly inorganic resin composition and a composition prepared thereby, the method comprising: step 1 (S1) in which, while maintaining a predetermined reaction temperature, alkoxysilane is hydrolyzed in an acid atmosphere to prepare a water-soluble alkoxysilane compound, and cellulose is added to the water-soluble alkoxysilane compound and is stirred to prepare a water-soluble cellulose alkoxysilane compound; step 2 (S2) in which alkoxysilane and ammonia, having been separately reacted with each other in an acidic aqueous solution, are added to the water-soluble cellulose alkoxysilane compound to prepare an alkoxysilane compound, and a silicate compound and alcohol, having been separately reacted with water, chloride, and oxalic acid at room temperature, are added to the alkoxysilane compound, and are mixed and stirred to prepare a modified silicate alkoxysilane compound; and step 3 (S3) in which the modified silicate alkoxysilane compound of S2 is mixed with the water-soluble cellulose alkoxysilane compound of S1. Thus, the composition is environmentally-friendly due to the reduction of volatile organic compounds that can cause environmental pollution, has enhanced adhesive force to a concrete surface due to having similar components as concrete, has improved durability, and can prevent yellowing.
