Abstract

The invention discloses an industrial flue gas pipeline maintenance protective coating layer and a preparation method thereof and belongs to the technical field of two-component epoxy glue. The maintenance protective coating layer is prepared from two components of A and B, wherein the component A is prepared from 30 to 45% of epoxy resin, 5 to 8% of diluent, 1 to 2% of coupling agent, 45 to 65% of wear-resisting filler and 3 to 5% of thixotropic agent; the component B is prepared from 85 to 95% of curing agent, 2 to 5% of accelerant, 0 to 20% of wear-resisting filler and 3 to 5% of thixotropic agent; the weight ratio of the component A to the component B is (5 to 8) to 1. The maintenance protective coating layer has the advantages of good adhesive property, good temperature resistance, good wear resistance, good corrosion resistance, good fa ade construction performance and the like; the problems of maintaining and protecting corroded and abraded industrial flue gas pipelines in a useprocess in the fields of power plants, steel mills, cement plants and the like are mainly solved; maintaining efficiency of the flue gas pipelines is improved, and service life of the flue gas pipelines is effectively prolonged.

Description

technical field [0001] The invention belongs to the technical field of epoxy adhesives, and in particular relates to an epoxy adhesive coating which can be applied to protective coatings for maintenance of industrial flue gas pipelines. Background technique [0002] Industrial flue gas pipelines are an important part of flue gas emissions from power plants, steel mills, cement plants and other industries, and the flue gas emitted generally has a certain temperature or even as high as 150°C, and the flue gas contains particulate dust, sulfur Corrosive substances such as chemical compounds and nitrogen oxides will cause certain erosion, wear, corrosion, aging and other damage to the flue gas pipeline with the continuous accumulation of pipeline operation time, thereby affecting the safety of industrial production and shortening the industrial smoke. service life of the gas pipeline. At present, the commonly used maintenance and protection methods for industrial flue gas pipel...
