Problems solved by technology

[0003] At present, the existing waterproof and leak-proof coatings mainly include solvent-based waterproof coatings and polyurethane waterproof coatings. The increasingly tense situation has inevitably led to rising costs of waterproof and leak-proof coatings
Moreover, the existing waterproof and leak-proof coatings have a long gel time after coating, which is not convenient and fast enough to use

preparation example Construction

[0010] The preparation method of the rapid gel plugging agent in this specific embodiment is as follows: after mixing liquid A, liquid B and liquid C in proportion, a polymerization reaction occurs to form an elastic water-insoluble polymer.

[0011] Wherein, the formula of the rapid gel plugging agent is further preferably: Liquid A is composed of the following raw materials in mass fractions: 9.5% of acrylamide, 0.5% of N,N'-methylenebisacrylamide, and 40% of water; Liquid B is composed of the following raw materials in mass fractions: 0.8% of β-dimethylaminopropionitrile; liquid C is composed of the following raw materials in mass fractions: ammonium persulfate 1.2%, water 48%.

Embodiment 1

[0012] Example 1: Rapid gel plugging agent, consisting of the following components in parts by weight: 47 parts of acrylamide in liquid A, 2.5 parts of N,N'-methylenebisacrylamide, 220 parts of water; 2 parts of methylaminopropronitrile; 2 parts of ammonium persulfate in C liquid, 220 parts of water. Mix the raw materials in liquid A, liquid B and liquid C according to the above parts by weight to form a water-insoluble polymer, fill and block the gaps in the sand layer under the floor tiles with the polymer, and condense in 3 minutes.

Embodiment 2

[0013] Example 2: Rapid gel plugging agent, consisting of the following components in parts by weight: 47 parts of acrylamide in liquid A, 2.5 parts of N,N'-methylenebisacrylamide, and 220 parts of water; liquid B: 2 parts of dimethylaminopropionitrile; 1.5 parts of ammonium persulfate in the third liquid, 220 parts of water, the raw materials in the first liquid, the second liquid and the third liquid are mixed according to the above-mentioned parts by weight to form a water-insoluble polymer, and the polymerization The body filler blocks the voids in the sand layer under the floor tiles and sets in 5 minutes.

Abstract

The invention discloses a rapid gel plugging agent, which relates to the technical field of leakage prevention and plugging in construction engineering. It contains liquid A, liquid B and liquid C. Liquid A is composed of the following mass fractions of raw materials: acrylamide 8%-12%, N,N'-methylenebisacrylamide 0.2%-1%, water 35%- 42%; liquid B is composed of the raw materials with the following mass fractions: β-dimethylaminopropionitrile 0.5%-1%; liquid C is composed of the raw materials with the following mass fractions: ammonium persulfate 1%-1.5%, water 45%-50 %, after mixing liquid A, liquid B and liquid C according to the formula ratio, the polymerization reaction will occur to form an elastic water-insoluble polymer. The formula does not contain carcinogenic compounds, is non-toxic and environmentally friendly, and can be used in roof waterproofing, wall seepage, toilet and kitchen leak prevention, etc. It has low viscosity, controllable gel time, fast operation, and better performance. It has the advantages of blocking water and strengthening the foundation.

Description

Technical field: [0001] The invention relates to a rapid gel plugging agent, which belongs to the technical field of leakage prevention and plugging in construction engineering. Background technique: [0002] With the development of my country's economy, the development of urban construction is advancing by leaps and bounds, and there are more and more high-rise buildings and bridge projects. In order to speed up the project progress and reduce costs, many construction units, coupled with natural factors such as acid rain, often have roof leaks, wall seepage or bathroom floor seepage in the completed buildings. These bring great trouble to people's life, affect the quality of life. Therefore, house leakage repair is a relatively common and extremely important task, and it is also important to choose a waterproof coating with good waterproof and leak-proof performance. The waterproof and leak-proof coating is painted on the surface of the building, and a thin film is formed...
