Composite flake heavy-duty coating for ocean storage and transportation facilities

Abstract

The invention discloses a composite flake heavy-duty coating for ocean storage and transportation facilities. The coating comprises the following ingredients in percentage by mass: 40-60% of film former, 2-10% of curing agent, 3-8% of modifying agent, 30-40% of composite filling, and more than 0 but less than 15% of diluent. The coating has an interpenetrating polymer network (IPN) structure, is wide in raw material resources, simple in conditioning technology and conductive to large-scale production and application, and the specifically modified coating is conductive to outdoor field construction. The composite flake heavy-duty coating is strong in adhesion, excellent in corrosion resistance, and suitable for application in oceanographic engineering and wild working condition, not only can protect a metal structure, but also can protect a nonmetallic structure.

Description

technical field [0001] The invention relates to a composite scale heavy-duty coating used in marine storage and transportation facilities. Background technique [0002] Corrosion involves almost all areas of the national economy, not only causing huge losses, but also hindering the development of new technologies and processes. There are usually two measures for corrosion control: one is remedial measures, which eliminate corrosion after it occurs; the other is preventive measures, that is, measures to prevent corrosion are taken in advance to avoid or delay corrosion. The practice of anti-corrosion shows that anti-corrosion coating is the most effective, most economical and most widely used method. Due to the continuous emergence of large-scale marine projects and the improvement of the application conditions of chemical engineering for the construction of anti-corrosion coatings, the requirements for adapting to harsh working conditions are constantly facing severe challe...
