Problems solved by technology

This not only requires professional equipment for the entire project construction, which increases the cost of the project, but also causes strong dust and noise pollution during the process of sand blasting and derusting
On the other hand, blasting fluid can cause thinning of the steel structure and reduce its strength, especially in the anti-corrosion repair of old steel structures
For the structural dead corners of complex working surfaces, the sandblasting treatment fluid cannot be cleaned thoroughly

Abstract

The invention belongs to the field of steel pipeline coatings for low surface treatment, and specially relates to a polypyrrole modified epoxide resin steel pipe coating for low surface treatment and a preparation method thereof. The coating is prepared by mixing a coating component and a curing agent component in a mass ratio of (4-5):1. The coating component is prepared from the following components in parts by mass: 17-20 parts of bisphenol A epoxy resin, 0.12-0.18 part of polypyrrole, 1.1-6 parts of pigments and fillers, 0.1-1 part of an anti-settling agent, 2-5 parts of a leveling agent and 1.76-2 parts of a solvent. The curing agent component is prepared from the following components in parts by mass: 2-4 parts of a curing agent and 1-2 parts of a solvent. The coating provided by the invention has a low organic solvent volatile performance and meets the environmental requirements. The coating consists of the coating component and the curing agent. Brushing and spraying construction processes can be adopted and the coating is simple to construct. The used film forming agent, various pigments and fillers, the anti-settling agent, the leveling agent and the curing agent are wide in source of raw materials, low in price and easy to get. The coating has lower treatment requirement on the surface of the base body, and the coating is simple to construct and low in project cost and can be widely applied.

Description

technical field [0001] The invention belongs to the field of low surface treatment steel pipeline paint, in particular to a polypyrrole modified epoxy resin low surface treatment steel pipeline paint and a preparation method. Background technique [0002] In the natural environment, most metals are prone to corrosion, which will lead to the destruction of the metal material structure and the loss of various functions. Organic coatings have the characteristics of low cost and easy construction, and have become the most widely used anti-corrosion coatings for metal materials. Among them, epoxy resin coating has many advantages such as strong adhesion and good chemical resistance, and has become the most widely used coating in organic coatings. [0003] In the anti-corrosion coating of steel structure, in order to ensure the anti-corrosion quality of the coating, it is necessary to carry out a thorough pre-sand blasting treatment on the steel, usually up to Sa2 1 / 2 class. Fo...
