Problems solved by technology

[0004] Although polyaniline has excellent anti-corrosion properties, its mechanical processing properties and compatibility with resins are poor, which limits its use.
The conventional methods for combining polyaniline with resin mainly include: Dissolution method: use a special solvent to dissolve and add it to the resin. This method will cause environmental pollution, poor construction conditions, and the expensive solvent will increase the cost sharply; Physical blending method: such as ball milling method, consumes a lot of energy and time, and its dispersion and stability in the resin are poor, which ultimately affects the performance of polyaniline's anti-corrosion performance; (3) first dissolve polyaniline in the amine curing agent , and then compounded with epoxy resin, this method has insurmountable defects: the content of polyaniline is low, and the content with the best anti-corrosion effect cannot be achieved

Abstract

The invention discloses an environment-friendly polyaniline anti-corrosion and anti-shedding coating. The coating comprises a component A and a component B, wherein the weight ratio of the component A to the component B is (10 to 1)-(20 to 1); the component A is prepared from the following components: (1) 53g of liquid epoxy resin E56, (2) 6g of diethylene glycol dibenzoate, (3) 0.5g of OP-10, (4) 10g of n-amyl alcohol, (5) 3g of ammonium persulfate, (6) 1.5g of distilled water, (7) 1g of 0.4mol / L camphorsulfonic acid water solution, (8) 10g of aniline, (9) 0.5g of methyl silicone oil and (10) 7g of neopentyl glycol diglycidyl ether; the component B comprises the following components: 110g of liquid fatty polyamine, 30g of polyaniline, 5g of quartz sand, 10g of ethylene glycol phenyl ether, 5g of talcum powder and 5g of rosin glycerin ester. The coating has the advantages of high polyaniline content, good anti-corrosion property, no pollution, low cost, and the like.

Description

technical field [0001] The invention relates to an environment-friendly polyaniline anti-corrosion and anti-shedding paint. Background technique [0002] The loss caused by metal corrosion to human beings is staggering. According to statistics, the global annual metal loss due to corrosion is as high as 20%-40% of global metal production, and the economic loss is about 1 trillion US dollars. Practice has proved that the use of coatings for corrosion protection of metals is the most economical, practical and effective method. However, the current commonly used anti-corrosion coatings contain a large amount of organic solvents, which cause great pollution to the environment during the construction process and pose a huge threat to the health of workers; at the same time, commonly used anti-corrosion coatings are also rich in zinc, which not only consumes a lot of zinc resources, but also affects the health of workers. The environment is seriously polluted by heavy metals....
