Organic silicon nano-precursor medium transmission inhibitor, its preparation method and use

An organic silicon nano-precursor medium transmission inhibitor, consisting of an organic silicon and its derivatives, a catalyst, a dispersant, a stabilizer, a surfactant, and water, which have following parts by weight:

• the organic silicon and its derivatives:
• 2-70 parts,
• the catalyst:
• 0.01-10 parts,
• the dispersant:
• 0.01-10 parts,
• the stabilizer:
• 0.01-5 parts, and
• the water:
• 30-95 parts;
• wherein the organic silicon and its derivatives are compounds have a linear or branch chain structure with 1 silicon atom to 1,000 silicon atoms, and the compounds have a molecular weight of 100-100000, and wherein the compounds are selected from silicate ester, alkyl silicate, alkyl siloxane, alkenyl siloxane, and alkyl siloxane with a functional heteroatom or polysiloxane with a functional heteroatom;
• wherein the catalyst does not initiate a reaction in a neutral environment, and initiates a reaction after the organic silicon nano-precursor medium transmission inhibitor is blended into a concrete, and wherein the catalyst is any one of phenol and its derivatives, benzoquinone and its derivatives, guanidine and its derivatives, and small molecule alcohol amine with a molecular weight of 50-1000;
• wherein the dispersant is a polymer dispersant formed by any one or two of acrylic acid and its derivatives, maleic acid and its derivatives, fumaric acid and its derivatives;
• and
• wherein the stabilizer is polysaccharide, chitosan, cellulose ether, polyamide, or polypyrrolidone.
