Description

Technical Field

[0001] The present invention relates to the technical field of cleaning agents, in particular to a cleaning agent for removing oil and wax, and a preparation method and application thereof. Background Art

[0002] During industrial production and processing, various types of dirt will form on the surface of equipment and workpieces. These dirt include oil stains, wax stains, etc., which need to be cleaned with corresponding industrial cleaning agents.

[0003] Oil stains on workpieces and equipment often form during the machining process, while wax stains are sometimes leftover from storage. During machining, residual oil and wax stains on workpiece surfaces can disrupt normal processing. Furthermore, oil and wax stains on equipment surfaces can affect normal operation and potentially cause equipment failure. Furthermore, oil and wax stains formed during storage can also affect appearance. In short, residual oil and wax stains on workpieces and equipment surfaces have significant negative consequences and require prompt cleaning.

[0004] Most existing technologies separate oil and wax removal, achieving good results for each. However, this approach leads to low efficiency, excessive time consumption, and high costs. Many traditional cleaning agents use components such as aliphatic hydrocarbons, ethanol, and petroleum distillates, which pose certain hazards to the environment and human health.

[0005] Therefore, it is of great significance to find an environmentally friendly cleaning agent that can remove oil and wax at the same time. Summary of the Invention

[0006] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides a degreasing and dewaxing cleaning agent, which has excellent decontamination effects on industrial oil and wax stains and is harmless to the human body and the environment.
