Problems solved by technology

At present, most of the domestic hydrocarbon cleaning agents volatilize into the atmosphere after use, causing environmental pollution. At the same time, the aromatic hydrocarbons, sulfur, and n-hexane components in the hydrocarbon cleaning agents will also cause harm to the human body and cause occupational disease injuries to employees at work. Therefore, Looking forward to more environmentally friendly hydrocarbon cleaning agents in the market
In an environment where the environmental protection situation is increasingly severe and the requirements for occupational disease protection are increasing, the physical and chemical properties of many hydrocarbon cleaning agents on the market cannot meet the requirements of downstream users
[0003] Moreover, for small electronic products, electronic components, precision hardware, and watch terminals with extremely high cleanliness, the existing hydrocarbon cleaning agents have poor cleaning ability, large pollution, long cleaning time and even corrosion.

Description

technical field [0001] The invention relates to the technical field of cleaning agents, in particular to an environment-friendly high-purity hydrocarbon cleaning agent and a preparation method thereof. Background technique [0002] The main component of hydrocarbon cleaners is alkanes, which are narrow fractions suitable for cleaning that are specially cut out by the distillation tower of a refinery, and then undergo delicate treatments such as hydrogenation process, desulfurization, dearomatization, impurity removal, and decolorization. Saturated alkanes are obtained, and then compounded with stabilizers, antioxidants, etc. to prepare hydrocarbon cleaning agents. The main components of hydrocarbon cleaning agents used in industry today are C9-C11 saturated straight-chain alkanes or saturated alkanes with few branched chains. At present, most of the domestic hydrocarbon cleaning agents volatilize into the atmosphere after use, causing environmental pollution. At the same ti...
