Description
Technical Field
The invention belongs to the technical field of cleaning agents, and particularly relates to a die-casting aluminum carbon steel bimetal composite material low-foam cleaning agent, and a preparation method and application thereof.
Background
With the technical development of the automobile industry and the requirement of energy conservation and emission reduction on the weight reduction of automobiles, the die-casting aluminum material is widely applied to the fields of core components such as automobile engines, speed reducers and the like and automobile parts by virtue of the advantages of good mechanical strength, low density, easiness in molding and processing and the like. With the development of material science and processing technology, workpieces made of die cast aluminum and carbon steel bimetal composite materials are also used in more applications, such as automobile speed reducer shells. The size and the residual quantity of particles on the surface of the shell are strictly controlled before the automobile speed reducer shell enters the assembly process, so that the stability of the use performance of the assembled speed reducer finished product is ensured, and therefore, the automobile speed reducer shell needs to be precisely cleaned to remove the metal micro powder, nonmetal powder scraps such as graphite powder, dust and other particle pollutants generated by CNC processing on the surface of a workpiece. The cleaning equipment before assembly adopts a unique cleaning process of spraying and injecting liquid, ultrasonic and drainage circulation, and the cleaning liquid needs to be treated by a precision filter before each start of spraying and injecting liquid so as to intercept particulate impurities carried in the cleaning liquid. Therefore, the cleaning procedure before assembling the die-casting aluminum-carbon steel bimetal composite material automobile speed reducer shell requires that the cleaning agent has good cleaning force, less foaming, quick defoaming, safety and no corrosion to the die-casting aluminum material and good antirust performance to the carbon steel, and in addition, the cleaning tank body has higher cost due to the special cleaning technology of equipment, the subsequent rinsing tank body is provided with less equipment, and the cleaning agent is required to have good rinsing performance.
Carbon steel and die-casting aluminum are both materials which are relatively easy to corrode, and most of the existing metal cleaning agent technologies can only be used for a single material and lack broad-spectrum applicability. Because of potential difference between the die-casting aluminum and the carbon steel, the die-casting aluminum carbon steel bimetal composite material is easy to generate electrochemical corrosion, and the difficulty of corrosion inhibition protection of the workpiece is further increased. Part of the existing cleaning agents are safe for single carbon steel and single die-casting aluminum, but serious corrosion is generated on carbon steel parts or die-casting aluminum parts when the die-casting aluminum carbon steel bimetal composite material is cleaned. In addition, a part of technologies are added with volatile organic solvents (VOC) to improve the cleaning effect, and under the use process of heating and spraying, the organic solvents are volatilized and released into the air more quickly, so that the environment is polluted, and the cleaning effect is reduced and the cleaning performance is unstable. Part of the prior art uses the surfactant component of high bubble to improve the cleaning performance, relies on the defoaming agent to control the foam of cleaner, has not only that the defoaming agent consumes the loss and the foam out of control overflow tank leaks the problem in the use, and the defoaming agent can cause the jam to the filter core of cleaning equipment before the assembly to influence washing liquid filtration cycle performance.
Disclosure of Invention
In order to overcome the defects and shortcomings in the prior art, the primary purpose of the invention is to provide a die-casting aluminum carbon steel bimetal composite material low-foam cleaning agent.
The cleaning agent disclosed by the invention is safe and corrosion-free to the die-casting aluminum carbon steel bimetal composite material, has good rust resistance, is stable and low in foam, is suitable for a spraying process, has a good cleaning effect on particles on the surface of a workpiece, is easy to rinse, and does not contain VOC.
The invention also aims at providing a preparation method of the cleaning agent.
It is a further object of the present invention to provide the use of the above cleaning agent.
The cleaning agent disclosed by the invention can be used for effectively removing particulate matters on the surface of a metal part, has an excellent corrosion inhibition effect on a die-casting aluminum carbon steel bimetal composite material, is safe and corrosion-free to a workpiece in the cleaning process, and can be used for obtaining short-term corrosion inhibition protection for 7-10 days after the workpiece is cleaned.
