Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a mist-suppressing and rust-removing agent and its preparation method, which solves the problem that the generation of a large amount of hydrogen in the acid solution treatment and rust removal process will cause hydrogen embrittlement of the steel and cause the mechanical properties of the metal to be damaged. Decrease, affecting the strength of the steel itself; at the same time, it is easy to form acid mist, which affects the health of operators and corrodes the surrounding equipment and environment; the consumption of acid is also large, which increases the processing cost; this kind of acid will cause excessive corrosion of steel; In addition, the residues produced in large quantities need to be discharged frequently, which not only seriously corrodes industrial pipelines, but also pollutes the soil and the environment.

Abstract

The invention discloses a mist-inhibiting rust remover and a preparation method thereof. The mist-inhibiting rust remover comprises the following raw materials in parts by weight: 4 to 10 parts of surfactant; 2 to 5 parts of amine product; 1 to 5 parts of corrosion inhibitor; and 60 to 80 parts of water. The invention relates to the technical field of chemical engineering. According to the mist-inhibiting rust remover and the preparation method thereof, 4 to 10 parts of the surfactant is arranged, the surfactant can foam and remove dirt on the metal surface, generated foam can play a role in blocking acid mist; 2 to 5 parts of alcohol amine product is arranged, so that the surfactant can be attached to the metal surface to avoid rusting after rust removal is finished; 1 to 5 parts of corrosion inhibitor is arranged, rust removal of hydrochloric acid can be assisted, the rust removal efficiency is improved; 60 to 80 parts of water is arranged to serve as a carrier solution; and 10 to 15parts of hydrochloric acid is arranged, the hydrochloric acid can be subjected to a chemical reaction with rust and metal oxide to generate soluble salt, so that the rust removal purpose is achieved.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to a fog suppressing and rust removing agent and a preparation method thereof. Background technique [0002] Ferrous metal (steel) is easy to rust when placed outdoors or in the open air, which not only affects the appearance quality, but also affects the normal progress of painting, bonding and other processes. Economic losses. [0003] Rust remover is also called rust loosening agent. Its main function is to loosen rusty fasteners, lubricate fasteners that cannot be disassembled, and facilitate the removal of rusty fasteners. It forms a durable corrosion protection on bare metal surfaces, preventing new rust from forming. The rust remover is also an ideal lubricating coolant, suitable for tapping the surface of stainless steel and aluminum plates. It can also effectively clean and dry electronic equipment and improve conductivity. It can be widely used in various ind...
