Title:
METHOD FOR PRODUCING ORGANIC-INORGANIC HYBRID HYDROGEL
Document Type and Number:
WIPO Patent Application WO/2019/009025
Kind Code:
A1
Abstract:
Provided is a method for producing an organic-inorganic hybrid hydrogel, the method comprising a step for mixing an aqueous solution (A) containing a water-soluble organic monomer (a1) and a phosphonic acid-modified hectorite (a2), a polymerization initiator (B), and a polymerization accelerator (C), wherein the viscosity of the aqueous solution (A) after the aqueous solution is prepared and then stored at 50°C for 1 week is 1000 mPa·s or less, the solubility of the polymerization initiator (B) in water at 20°C is at least 50 g/100 ml, and the molar ratio [(B)/(a1)] of the polymerization initiator (B) to the water-soluble organic monomer (a1) is in the range of 0.01-0.1. This method for producing an organic-inorganic hybrid hydrogel exhibits excellent workability due to having long-term storability in a state just before polymerization, and can have various industrial applications in construction sites such as civil construction sites due to not being restricted in terms of production location and the like.
