Abstract

The invention discloses an organic-inorganic composite water plugging reinforcement material and a preparation method thereof. The material consists of a component A and a component B, wherein the component A comprises the following ingredients by weight percent: 97-99% of water glass, 0.5-1.5% of a chain extension cross-linking agent, 0.2-0.6% of an organo-metallic catalyst, and 0.3-0.9% of an amine catalyst; the component B comprises the following ingredients by weight percent: 65-75% of crude MDI, 0-8% of PPG (polypropylene glycol)-2000, 2-10% of polyether triol 330N, 14-23% of a diluent and 1-2% of a foam stabilizer; the mass ratio of the component A to the component B is 1:(0.7-1.2). The preparation method comprises the following steps: mixing the ingredients of the component B according to the weight percent, leaving the mixture to stand for 12 hours, adding the component A, and uniformly stirring, so as to obtain the water plugging reinforcement material which is high in strength, good in environment friendliness and durability, non-flammable, and low in cost. According to the invention, the limitation problem that a polyurethane water plugging material can be used for reinforcement or plugging of a small amount of leakage water only.

Description

Technical field [0001] The invention relates to the field of water blocking materials, in particular to an organic-inorganic composite water blocking reinforcement material and a preparation method thereof. Background technique [0002] Organic reinforcing materials are generally composed of polyisocyanate (crude MDI, commonly known as black material) and combined polyether (multifunctional polyether, small alcohol, flame retardant and other additives, gel catalyst, strong blowing catalyst or trimerization catalyst) It is a polymer material formed after mixing one or two or more of them, commonly known as white material. The existing polyurethane reinforcement materials are not only extremely expensive, but also easy to dissolve in water, cannot block a large amount of water gushing, and especially cause great pollution to the water body. Summary of the invention [0003] The purpose of the present invention is to provide a low-cost, environmentally friendly organic-inorganic...
