High-performance solvent-free epoxy heavy anti-corrosion material

Abstract

The invention relates to the technical field of anticorrosive materials, and discloses a high-performance solvent-free epoxy heavy-duty anticorrosive material, which is prepared from the following components in percentage by mass: 20 to 30 percent of polyester resin, 5 to 10 percent of epoxy resin, 10 to 15 percent of polyamide, 2 to 5 percent of calcium carbonate, 4 to 7 percent of dispersing agent, 0.5 to 2 percent of coupling agent and filler, and is good in dispersion property and capable of preventing mutual aggregation of filler particles; proper compatibility with resin and filler is realized; the thermal stability is good; the flowability is good during forming processing; color drift is not caused; according to the present invention, the product performance is not affected, the viscosity of the synthetic resin melt can be reduced during the processing process, and the dispersity of the filler can be improved so as to improve the processing performance, such that the product has good surface quality and good mechanical, thermal and electrical properties. The material has the characteristics of low viscosity, good mechanical property, excellent chemical property and the like, and the properties such as heat resistance, water (moisture) resistance, insulation and the like, especially the processing (operation) and mechanical properties, are remarkably improved.

Description

technical field [0001] The invention relates to the technical field of anti-corrosion materials, in particular to a high-performance solvent-free epoxy heavy-duty anti-corrosion material. Background technique [0002] At present, in my country's petroleum refining and chemical industry, traditional thermal insulation materials are mostly porous loose materials, such as rock wool, glass wool, perlite, foamed polyurethane, etc. The material has a high water absorption rate, which can exceed 200%. Some data show that once the water absorption rate exceeds 40%, the thermal insulation effect will be seriously damaged. In order to solve the problem of water absorption of the material, a galvanized iron sheet or aluminum sheet with a diameter of 1-2m is usually covered with the insulation material. At the same time, this thermal insulation system is not easy to cover the elbows, joints and valves of the pipeline, making it exposed to the air and more susceptible to corrosion. Corr...

Problems solved by technology

In order to solve the problem of water absorption of this material, a galvanized iron sheet or aluminum sheet with a diameter of 1-2m is usually coated on the insulation material. The direct consequence of this is that the cost will increase significantly, resulting in high production costs and construction difficulties. ; At the same time, this insulation system is not easy to cover the elbows, joints and valves of the pipeline, so that it is exposed to the air and is more susceptible to corrosion

Corrosion not only causes huge economic losses, but also brings many hidden dangers to safe production. Failure to solve the problem of equipment corrosion will seriously affect normal production
