Description

Environment-friendly cleaning agent and preparation method and application thereof Technical Field The invention belongs to the technical field of preparation of lubricating cleaning agents, and particularly relates to an environment-friendly cleaning agent, a preparation method and application thereof. Background The chain is used as a core component of a transmission system, is exposed to complex environments (sediment, greasy dirt, rainwater and the like) for a long time, and needs to be cleaned regularly to reduce abrasion. Traditional mechanical cleaning efficiency is low, and manual scrubbing is consuming time and is difficult to thoroughly clear away the stubborn spot in chain gap, and ultrasonic cleaning equipment cost is higher. The early cleaning agents are mainly petroleum-based solvents, and mostly adopt solvents such as kerosene, diesel oil and the like, and have the problems of flammability, high emission of VOCs, poor biodegradability and the like although the detergency is strong. The existing partial cleaning agent optimizes the environmental protection performance or adopts the combination of components such as biological enzyme, alkyl glycoside, siloxane, silicon dioxide and the like, but lacks a targeted rust-proof protection system, has insufficient passivation protection on the metal surface of the chain, has poor synergistic effect of cleaning and rust prevention, and is difficult to meet the requirements of efficient decontamination and long-term rust prevention. The traditional chain cleaning agent (such as kerosene, diesel oil, detergent and the like) has the following defects that 1. The traditional chain cleaning agent has strong corrosiveness, and lubricating grease and electroplated coating inside a chain are damaged, so that the service life of the chain is shortened. 2. The environment pollution is that phosphorus-containing and benzene-containing substances are difficult to degrade and do not accord with the European Union REACH environmental protection standard. 3. The operation risk is that Volatile Organic Compounds (VOCs) are liable to cause respiratory tract irritation. 4. The residual problem is that the cleaning needs to be performed for the second time, otherwise, the dust absorption accelerates the abrasion. 5. The decontamination limitation is that biological enzymolysis is lack, the decomposition efficiency of triglyceride oil stains and protein stains is low, and the cleaning is incomplete. 6. The protection is insufficient, the existing formula containing alkyl glycoside, biological enzyme, siloxane or silicon dioxide does not construct a targeted metal passivation protection system, rust is easy to generate after the chain is cleaned, and the cooperative optimization of cleaning and rust prevention cannot be realized. Therefore, it is desirable to provide a cleaning agent which has a high oil stain removal rate and is environmentally friendly, and which also has an anti-rust function.
