Abstract

The invention discloses no-flash-point industrial detergent. The compositions by weight percentage of the no-flash-point industrial detergent are: 15 to 45 percent of 3-methoxyl butyl alcohols, 15 to 52 percent of N-methyl pyrrolidone, 16 to 28 percent of 2-methyl pentanediol and 12 to 28 percent of active solvent. The no-flash-point industrial detergent has the advantages of safety and environmental protection, no corrosion, strong decontaminating and dissolving capacity, good stability, ozone depletion potential ODP and GWP being zero, etc.

Description

【Technical field】 [0001] The invention relates to an industrial cleaning agent, in particular to a cleaning agent which is safe, environment-friendly and has strong cleaning power and is suitable for precision hardware, electronic appliances and optical instruments. 【Background technique】 [0002] At present, the proportion of ODS cleaning agents in industrial cleaning agents is relatively large, especially in hardware and electronic cleaning agents, trichloroethylene, dichloromethane and trifluorotrichloroethane have a wide range of applications and wide adaptability, and have attracted much attention. However, ODS cleaning agents are toxic substances. According to the "Overall ODS Elimination Plan for China's Cleaning Industry" signed by China and the Montreal Fund, China will phase out ODS cleaning agents. [0003] Therefore, finding alternatives to replace ODS cleaning agents has become a top priority for the cleaning agent industry, and various new cleaning agents have ...
