Abstract
The invention provides a stainless steel surface dedusting agent which is characterized by comprising the following components in percentage by weight: salicylic acid 2.3-7.3%, nitric acid 12.3-14.3%, dessimidine oxidant 1.8-2.8%, lauric acid 5.0-7.1%, and water in balance. The stainless steel surface dedusting agent can completely remove the stainless steel surface oxidation film, and clean the viscous film, black carbide and black impurities during subsequent roughening treatment so as to ensure the binding force of the stainless steel matrix with plastics, glue and paint.
Description
Technical Field
The invention belongs to the technical field of metal treatment, and particularly relates to a stainless steel surface dedusting agent and a preparation method thereof.
Background
The surface of stainless steel is chemically treated (chemically corroded) to obtain a micro-rough structure on the surface of stainless steel, which changes the hydrophobicity into hydrophilicity to increase the binding force between paint, plastic or glue and the surface of stainless steel.
The surface chemical roughening process is used for improving the adhesion of the metal surface to the anticorrosion, shock-insulation and noise-reduction material. In the industry of vibration isolation and noise reduction, steel and stainless steel surfaces are adopted more frequently. For steel and stainless steel workpieces, when corrosion prevention, shock insulation and noise reduction treatment is carried out, if micro-roughening treatment can be carried out on the surfaces of the steel and stainless steel workpieces, the micro-roughened surfaces can obviously improve the real surface area of the metal surfaces, and further improve the adhesion performance of the surfaces of the steel and stainless steel to corrosion prevention layers and shock insulation and noise reduction materials. The stainless steel surface dedusting agent of the invention is an indispensable process for better forming a roughened surface on the stainless steel surface by using the roughening solution.
Disclosure of Invention
In order to overcome the defects in the prior art, one of the objectives of the present invention is to provide a stainless steel surface deashing agent, which completely removes the oxide film on the surface of the stainless steel, and cleans the adhesive film, black carbide and black impurities during the subsequent roughening treatment, so as to ensure the binding force of the stainless steel substrate with plastic, glue and paint.
The second purpose of the invention is to provide a preparation method of the stainless steel surface dedusting agent.
The invention also aims to provide the application of the stainless steel surface dedusting agent in the pretreatment of stainless steel surface roughening.
The stainless steel surface dedusting agent is prepared from the following components in percentage by weight:
preferably, the stainless steel surface ash remover is prepared from the following components in percentage by weight:
the invention must adopt salicylic acid, nitric acid and lauric acid at the same time, and under the condition of the same total acid amount, any one is lacked, and the ash removal effect is poor.
The preparation method of the stainless steel surface dedusting agent comprises the following steps:
weighing the components, blending, stirring and dissolving uniformly.
The stainless steel surface dedusting agent formula of the invention adopts the following treatment method to carry out dedusting treatment on stainless steel: soaking stainless steel for 2-10 min for deashing treatment under the conditions that the bath solution temperature is 55-65 ℃, the stock solution is put into the bath and the pH value is less than 0.5; cleaning the stainless steel subjected to ash removal treatment, wherein the cleaning mode comprises soaking water washing or spraying water washing; and (4) baking the cleaned stainless steel at high temperature or drying the stainless steel by hot air.
A large amount of black carbides and other black impurities are generated on the stainless steel matrix after coarsening, even the adhesive film is not cleaned, and the effect of deashing is to clean the adhesive film, the black carbides and the black impurities so as to ensure the binding force of the stainless steel matrix with plastics, glue and paint.
Detailed Description
The present invention is further illustrated by the following examples, which are not intended to be limiting.
Table 1 shows the formulations of examples 1 to 5 and comparative examples 1 to 2 in wt%.
Table 1 formulations of examples 1-5 and comparative examples 1-2.
The preparation method of the stainless steel surface dedusting agent comprises the following steps:
the components are weighed, blended, stirred and dissolved uniformly.
The use method of the stainless steel surface dedusting agent comprises the following steps:
soaking stainless steel for 2-10 min for deashing treatment under the conditions that the bath solution temperature is 55-65 ℃, the stock solution is put into the bath and the pH value is less than 0.5; cleaning the stainless steel subjected to ash removal treatment, wherein the cleaning mode is spray water cleaning; and (4) drying the cleaned stainless steel by hot air.
The use effects of the above examples and comparative examples are as follows:
