Elastic material for leaking stoppage and repair of pipeline

Abstract

The invention relates to the technical field of leaking stoppage and repair, and discloses an elastic material for leaking stoppage and repair on a pipeline, and a preparation method of the elastic material comprises the following steps: preparing the following materials, the high-toughness epoxy resin material is prepared from the following components in parts by weight: 10-20 parts of bisphenol A type epoxy resin, 10-20 parts of bisphenol F type epoxy resin, 20-30 parts of aromatic epoxy resin, 1-2 parts of a coupling agent, 25-30 parts of aromatic isocyanate, 5-10 parts of amine-terminated polyether, 3-7 parts of iron powder, 3-7 parts of aluminum powder, 1-2 parts of an antioxidant, 1-2 parts of a catalyst, 1-2 parts of a super-toughness modifier and 3-7 parts of a diluent. According to the invention, the super-tough modifier is utilized to increase certain toughness of the material for leaking stoppage, so that the component A material has flexibility and better elasticity and better adapts to thermal expansion and cold contraction of the composite pipeline, and when the composite pipeline expands with heat and contracts with cold, pulling and extruding force can be generated on the elastic material, so that the elastic material deforms under stress, and corresponding elastic potential energy is generated; after the composite pipeline is reset, the elastic material can be reset under the action of elastic potential energy, and the phenomenon of notches is avoided.

Description

technical field [0001] The invention relates to the technical field of plugging and repairing, in particular to an elastic material used for plugging and repairing leakage on pipelines. Background technique [0002] Plugging repair refers to a method of repairing the location of water leakage, air leakage or material leakage on the pipeline, which is used to repair and reduce the cost of pipeline replacement. [0003] After the existing leak plugging and repairing materials are repaired at the leak location, the leak location is prone to slight deformation due to thermal expansion and contraction, so that the inner diameter of the leak is indeterminate, and the material used for leak plugging and repairing will also be heated. The expansion and contraction affect the deformation, so that although it has a certain hardness and stability, it lacks elasticity, so that it cannot cover the surface of the hole more completely, and it is prone to gaps (new holes), which makes it di...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides an elastic material used for plugging and repairing pipelines, which solves the problem that the inner diameter of the leak is indeterminate due to slight deformation caused by heat expansion and contraction at the position of the leak, and the use of The materials used for plugging and repairing will also be deformed by heat expansion and contraction, so that although it has a certain hardness and stability, it lacks elasticity, making it unable to cover the surface of the leak more completely, and is prone to gaps (new Vulnerabilities), so that it has poor patching effect on the position of the vulnerability and reduces the problem of usage
