House leakage repair high-viscosity cold-flow adhesive tape and preparation method thereof

Abstract

The invention discloses a house leakage repair high-viscosity cold-flow adhesive tape, which is composed of, successively, a protective film, a house leakage repair high-viscosity cold-flow adhesive layer, and an isolation film. The protective film is a polyester film and the isolation film is a polyethylene film. The house leakage repair high-viscosity cold-flow adhesive layer is composed of, by weight, 28-31% of medium-molecular polyisobutylene, 15-18.5% of low-molecular polyisobutylene, 10-13.5% of liquid state polysulfide rubber, 43-46.5% of calcium stearate, and 0.5-1% of an antioxidant. A preparation method of the adhesive tape includes the steps of: kneading the raw materials into glue mud, feeding the glue mud into a reaction kettle to blend the glue mud, extruding the glue mud through an extruder, coating the isolation film with the glue mud, laminating the protective film, and rolling the adhesive tape through a double-roller to produce the product. The house leakage repair high-viscosity cold-flow adhesive tape has cold-flowability and auto-repairing function and can be used for seam repairing and leakage prevention for top floor of a house and leakage repairing for a fish tank and a circulating water tank.

Description

technical field [0001] The invention belongs to a house leak-trapping adhesive and its preparation, and relates to a house-trapping high-viscosity cold-flow adhesive tape and a preparation method thereof. The leak-trapping high-viscosity cold flow adhesive tape for houses of the present invention is especially suitable for leak-tightening gaps and leak-proofing on roofs and indoors of houses, and can also be used for leak-trapping of flowing water circulation boxes and containers such as pots and fish tanks. Background technique [0002] The gaps in the roof of the house are a major problem in the leakage prevention of houses in our country. The roof of the house designed by the architectural design institute generally needs to be treated with two or three layers of waterproof cloth. However, due to the cumbersome construction process, the quality of the construction will be slightly relaxed Cause roof cracks, and deal with roof leakage will cost about five times of the orig...

[0002] The gaps in the roof of the house are a major problem in the leakage prevention of houses in our country. The roof of the house designed by the architectural design institute generally needs to be treated with two or three layers of waterproof cloth. However, due to the cumbersome construction process, the quality of the construction will be slightly relaxed Causes cracks in the roof, and it will cost about five times the original construction cost to deal with the roof leaks

In the prior art, to deal with roof leaks, the main method is to pry open the gaps with a drill first, and then use asphalt glass cloth and waterproof cloth to pour cement. This method is difficult to solve the problem of leaks in the gaps; Roof or indoor gap repair, but the sealing effect is poor, it is difficult to keep the gap sealed for a long time
