Problems solved by technology

However, after the stable rust paint generally uses active pigments, the anti-corrosion performance is not good, and it is generally used as a primer, and some stable paints use chromate and lead salt active paints. These pigments are toxic and will cause environmental pollution. Pollution

Abstract

The invention relates to the field of anticorrosive coatings, in particular to an epoxy rust graphene anticorrosive coating and a preparation method thereof. The epoxy rust graphene anticorrosive coating is prepared from the following components in percentage by weight: 0.1 to 5 percent of graphene, 30 to 60 percent of epoxy resin, 20 to 40 percent of an active pigment, 10 to 30 percent of a pigment filler, 0.1 to 10 percent of a dispersant, 0.1 to 5 percent of a coating additive and 8 to 30 percent of a solvent. According to the coating provided by the invention, all the components achieve asynergetic enhancement effect; the obtained coating is tightly combined with a rust layer and is excellent in anticorrosive property; rust spray coating, long-acting corrosion prevention and a primer-topcoat type are realized. According to the corresponding preparation method, all the components work synergistically, and the coating with uniformly dispersed graphene powder is obtained. The methodis simple, convenient and feasible in preparation, and the prepared coating is excellent in performance.

Description

technical field [0001] The invention relates to the field of anticorrosion coatings, in particular to an epoxy rusty graphene anticorrosion coating and its preparation method and application. Background technique [0002] To adopt anti-corrosion coating on metal equipment, strict pre-treatment must be carried out on the metal surface. Sand blasting is used to pre-treat steel, which is expensive (usually accounts for 30% to 40% of the entire project), and at the same time causes strong dust and noise pollution, and cannot completely treat the dead corners of complex work surfaces, and it is difficult to meet the specified standards. , especially sandblasting will cause the thinning of the steel structure and reduce its strength. There is a new trend at present, which is to replace the traditional sandblasting process with high pressure water derusting and wet sandblasting, but it is difficult to meet the requirements of SA 2.5 level. If you use rust paint as a primer, these...
