Abstract

The invention belongs to the technical field of anti-corrosion treatment processes, and particularly relates to a steel structure house anti-corrosion treatment process which comprises the following treatment steps: s1, weighing raw materials of a component A; s2, uniformly dispersing the raw materials of the component A to obtain the component A of an antirust coating; s3, weighing the raw materials of a component B; s4, uniformly dispersing the raw materials of the component B to obtain the component B of the antirust coating; s5, performing polishing and cleaning pretreatment on the surface of the steel structure; s6, uniformly mixing the antirust coating component A and the antirust coating component B according to the mass ratio of 10: 3 to obtain the steel structure antirust coating; and s7, coating the surface of the steel structure with the prepared steel structure antirust coating. The mechanical property, the water resistance, the heat resistance and the surface performance of the coating are greatly improved, the defects that a traditional coating is poor in mechanical strength, abrasion resistance, ultraviolet aging resistance, water resistance, scrubbing resistance, stain resistance and aging resistance are overcome, and the salt fog resistance is excellent.

Description

technical field [0001] The invention relates to the technical field of anti-corrosion treatment technology, in particular to an anti-corrosion treatment process for steel structure houses. Background technique [0002] Steel structure is a structure composed of steel materials, which is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of section steel and steel plates, and adopts rust removal and antirust processes such as silanization, pure manganese phosphating, washing and drying, and galvanizing. The components or components are usually connected by welds, bolts or rivets. Because of its light weight and easy construction, it is widely used in large factories, stadiums, super high-rises and other fields. [0003] Because the steel structure is easy to corrode, the steel structure used in the residential area needs to be derusted and antirust. Form an anti-corrosion pro...
