Abstract

The invention discloses flexible coating for corrosion prevention and renovation of a reticular steel frame structure and a preparation method of the flexible coating. The flexible coating is preparedfrom the following raw materials in parts by weight: 45-60 parts of epoxy resin, 10-15 parts of a diluent, 10-15 parts of whisker zinc oxide, 5-10 parts of hollow glass beads, 2-4 parts of a wettingdispersant, 2-4 parts of n-butyl alcohol and 10-15 parts of a filler. The TVOC release amount of the flexible coating is obviously decreased, and the flexible coating has excellent flexibility, agingresistance, yellowing resistance and corrosion resistance performance and can resist acid, alkali, oil and an organic solvent. 100 microns or above can be reached through one-time film coating, and thus the construction requirements can be met generally through two passes of spraying.

Description

technical field [0001] The invention relates to the technical field of coatings and preparation methods thereof, in particular to a flexible coating used for anticorrosion and renovation of reticular steel frame structures and a preparation method thereof. Background technique [0002] The mesh steel frame structure is a space structure formed by connecting multiple rods through nodes according to a certain grid form. It has the advantages of small space force, light weight, high rigidity, and good seismic performance; it can be used as the roof of gymnasiums, theaters, exhibition halls, waiting halls, stadium stand awnings, hangars, and workshops with two-way large column spacing. The disadvantage is that the number of rods that meet at the nodes is large, and the fabrication and installation are more complicated than the planar structure. [0003] The mesh steel frame structure is used outdoors, and the biggest problem it faces is metal corrosion. [0004] Metal corrosio...
