Abstract

The invention discloses a two-component impervious environment-friendly material for a pipeline. The material is prepared by mixing a component A and a component B in a weight ratio of 1: 1-3. The component A comprises 7 to 10 parts of toluene diisocyanate, 10 to 15 parts of methyl diphenylene diisocyanate, 35 to 50 parts of polyether polyol-1, 10 to 15 parts of polyether polyol-2, 0 to 20 parts of epoxy resin and 1 to 10 parts of an environment-friendly diluent. The component B comprises 4 to 5 parts of an amine cross-linking chain extender, 20 to 45 parts of polyether polyol-3, 5 to 10 parts of polyether polyol-4, 10 to 15 parts of a plasticizer, 40 to 55 parts of talcum powder, 1 to 10 parts of zinc oxide, 1 to 10 parts of sericite powder, 10 to 20 parts of barium sulfate precipitate, 1 to 4 parts of organic bentonite, 10 to 20 parts of an active nanometer filling material, 5 to 10 parts of a reinforcing agent, 10 to 20 parts of a diluent, 1 to 2 parts of a catalyst and 0.1 to 1 part of an auxiliary agent. The material provided by the invention has integrated environment friendliness, wear resistance, impermeability and high elongation percentage; nanotechnology is introduced so as to further improve the application performance of the material; and the material is specially applied to pipelines, and pipelines prepared from the material are environment-friendly and have long service life.

Description

technical field [0001] The invention belongs to the technical field of anti-seepage materials for pipelines, in particular to a two-component anti-seepage environmental protection material for pipelines and a preparation method thereof. Background technique [0002] Corrosion of steel pipes generally exists in various sectors of the national economy and national defense construction, which not only brings huge losses to the national economy, but also causes great difficulties to production and life. Under natural conditions (atmosphere, natural water body, soil) or artificial conditions (acid, alkali, salt and other media), steel pipes are corroded all the time. It is a spontaneous and unnecessary consumption. The fundamental reason is that steel pipes are in a thermodynamically unstable state. Under the above conditions, they will return to their original relatively stable state, generate iron oxide carbonate, etc., or transform into soluble ions. This process is the corro...
