Description

A kind of hardware oil stain cleaning agent and preparation method thereof

technical field

The invention relates to the technical field of cleaning agents, in particular to a hardware cleaning agent for oil stains and a preparation method thereof. the

Background technique

Precision hardware is the crystallization of the development of multidisciplinary technology. It has now expanded from the application of watches and calculators to various aspects such as instruments, communication equipment, and notebook computers. Therefore, the technology-intensive and capital-intensive high-tech industries should be based on precision hardware As one of the main materials of precision instruments. In the process of precision hardware processing, it is inevitable that cutting oil, spark oil, drawing oil, grinding oil, embossing oil, release oil, anti-rust oil, stamping oil and other oil stains will inevitably adhere to the surface of the workpiece. On the surface, it will affect the smooth progress of the next process, the processing quality and aesthetics of the workpiece. Therefore, all kinds of oil stains attached to precision hardware must be removed before entering the next process or before transformation. the

White electric oil, the scientific name is n-hexane, because of its high fat solubility, high volatility, and strong decontamination ability, it is often used as one of the components of cleaning agents in industry, especially in the fields of hardware, electronics, printing, etc. application. However, white electric oil is extremely polluting to the environment, and its vapor can cause symptoms of eye and upper respiratory tract irritation, which is extremely harmful to human health. In addition, white electric oil has a low boiling point and evaporates quickly, so it stays on the surface of the workpiece for a long time. Short, it is difficult to clean the workpiece thoroughly. Therefore, it is urgent to develop a cleaning agent that can replace white electric oil components. the
