Description
Technical Field
The invention belongs to the technical field of functional materials and welding, and particularly relates to a welding anti-splashing agent for engineering machinery, and a preparation method and application thereof.
Background
With the development of engineering mechanical equipment to the directions of high strength and heavy load, welding becomes one of the most important processes in the engineering mechanical equipment, and the quality of welding is a key for influencing the operation of the engineering machinery. The on-site welding method for engineering machinery manufacturing mainly has the characteristics of manual arc welding, semi-automatic welding gas shielded welding and the like, and the distribution of welding beads is dense, intermittent, irregular and the like, and the two welding methods are also easiest to produce welding spatter which can directly influence the quality of welding seams of engineering machinery and cause obstruction to subsequent coating; and the complex postweld slag removal work is brought to operators on the welding site of the engineering machinery. How to reduce or even eliminate the adverse effects of welding spatter from the aspects of materials, equipment, processes and the like is one of the important difficulties to be solved in the welding field.
Welding spatter is mainly caused by the fact that when a short-circuit liquid bridge is contracted to be thin, the short-circuit current rapidly heats the liquid bridge, so that the liquid bridge is gasified and explodes. During the welding process, spatter is caused by metallurgical reactions, pole pressures, droplet shorts, non-axial droplet transitions, and mismatching of welding parameters. The splashing can seriously affect the appearance quality of welding, occupy a large amount of grinding time, damage the welding tool and cause adverse effects on the follow-up flaw detection process, coating process and quality. The traditional method for eliminating the spatter on the welding site mainly relies on manual polishing, and a hand-held grinder is adopted to polish the spatter on the surface of the pipeline. The operation environment is bad for operators, the operation environment is heavy, the operators are also faced with the invasion of a large amount of metal dust, the metal dust is reserved on a construction site, and the environment is damaged to different degrees. Moreover, the quality of manual polishing cannot be guaranteed, damage to the surface of the machine can be caused by improper operation, the subsequent coating is adversely affected, and potential safety hazards can be seriously brought to the operation of engineering machinery.
In recent years, a plurality of welding anti-splashing agents are also appeared, such as a patent of 'a welding anti-splashing agent for alloy steel plates and a preparation method thereof', and CN104057215A discloses a welding anti-splashing agent for galvanized steel plates and a preparation method thereof, which are characterized in that the original welding process and mechanical properties are not changed, and a non-splashing effect is achieved. However, the invention belongs to oil-based type, uses mechanical oil as an organic solvent, is not easy to remove in site operation after being coated on the surface of a workpiece, can possibly influence the subsequent coating pretreatment, and contains lead and toluene substances harmful to human bodies. And the components are more, the process is complex, and the use cost is high. The patent "welding anti-spatter liquid", CN101386716a discloses a welding anti-spatter liquid which prevents a welding ball formed by spatter from adhering to a welded product during welding, and has good cleanability, but a large amount of gas is generated during the use of the welding anti-spatter liquid, especially in a welding area, and the probability of occurrence of air hole defects of a welding line is increased.
Therefore, the anti-splashing agent which is economical and environment-friendly and is suitable for the field intensive welding of engineering machinery is further explored and optimized, and has important research and application significance.
