Treatment process of low-carbon steel-zinc aluminum stainless steel composite material

Abstract

The invention discloses a treatment process of a low-carbon steel-zinc aluminum stainless steel composite material. The treatment process comprises the following steps: firstly, a certain quantity ofhigh-molecular polymers 8586 are weighed; secondly, a certain quantity of water is fed for dilution to obtain high-molecular polymer 8586 water solution; finally, titanium powder and zinc powder are fed for uniform stirring to obtain paint; oil and rust of prepared steel pieces are removed; the steel pieces are wiped by using filter papers after oil and rust removal to obtain pretreated steel pieces; the paint is coated on the pretreated steel pieces; and the paint-coated steel pieces are heated for curing in a drying box. The treatment process of the low-carbon steel-zinc aluminum stainless steel composite material adopting the structure is simple in process treatment procedure; the aluminum powder and the titanium powder can be preferably and stably fused in a liquid-phase system; and through the content increment of the aluminum powder, the impact and corrosion resisting time of low-carbon steel coating layers is prolonged, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of anti-corrosion and derusting processes, in particular to a process for treating low-carbon steel-zinc-aluminum stainless steel composite materials. Background technique [0002] Metal corrosion has brought huge losses to the national economy. In my country, the economic loss caused by metal corrosion is as high as 30 billion yuan per year. For a long time, the most commonly used anti-corrosion method is to apply an anti-corrosion coating or electroplating on the metal surface to form a metal anti-corrosion layer to isolate the contact between the corrosive medium and the metal substrate. At present, the anti-corrosion coatings coated on ordinary metal surfaces are organic solvent-based polymer coatings. Although they have the effect of inhibiting corrosion, they contain volatile solvents and heavy metals that are easy to cause damage to the human body, causing serious environmental problems. pollution p...

At present, the anti-corrosion coatings coated on ordinary metal surfaces are organic solvent-based polymer coatings. Although they have the effect of inhibiting corrosion, they contain volatile solvents and heavy metals that are easy to cause damage to the human body, causing serious environmental problems. pollution problem

[0003] Although the traditional electroplating method has a mature process, it causes serious environmental pollution and high cost because most of the electroplating solutions contain highly toxic cyanide
