Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of precision instrument cleaning, in particular to a rust-proof multifunctional biological-based precision instrument cleaning agent and a preparation method thereof. BACKGROUND

[0002] With the rapid development of global electronic information technology, the requirements for the electronicization and automatic control of industrial equipment are becoming higher and higher, leading to the rapid growth of the production and use of electronic, electrical and other precision instruments. The urgent needs of the normal operation and maintenance of electronic, electrical and other precision instruments have put forward strict requirements for cleaning agents and brought great opportunities. In most cases, in order to meet the needs of production and life, it is usually required that precision instruments can work continuously, so it is required that the equipment can be cleaned without power failure and work stoppage during maintenance, and the cleaning agent should have excellent properties such as high insulation, non-combustibility, easy volatilization, environmental protection, etc., and can quickly and effectively remove various dirt on the surface and in the deep layer of the equipment; most precision instruments are metal instruments, so attention should be paid to the rust problem of the metal during cleaning and storage after cleaning; at the same time, attention should also be paid to the degradability of the cleaning agent to avoid environmental pollution. Therefore, it is of great significance to develop a rust-proof multifunctional biological-based precision instrument cleaning agent.

[0003] At present, the charged cleaning agent for precision instruments mainly uses high-insulation, non-combustible, easy-volatilization solvents, cosolvents and surfactants to remove oil stains and dust on the surface of precision instruments under normal working conditions.

[0004] A kind of charged cleaning agent for precision instrument as described in CN104479905A, its formula includes cleaning agent includes coconut oil pthamide propyl betaine, nonylphenol polyoxyethylene ether, tetradecyl dimethyl benzyl ammonium chloride, sodium tripolyphosphate, trisodium phosphate, sodium bicarbonate, sodium nitrite, 2-phenoxyethanol, pine oil, antistatic agent, polyhydroxy polyamine, ethyl acetate and ethanol.But due to the low boiling point, high volatile ethyl acetate and ethanol in cleaning agent, in the charged operation is extremely easy to produce explosion and other dangers.A kind of precision instrument cleaning agent for cleaning precision instruments such as electronic network, as described in CN02109922.7, avoids low boiling point and high volatility solvent, adopts trichloroethane 90-150 parts, diethylene glycol 50-80 parts, carbon tetrachloride 700-50 parts, methyl alcohol 10-30 parts as formula, obtains good insulation performance, can be charged cleaning, safe and reliable, in the case of not power-off, quickly removes dust, oil stains, moisture and other of various precision electronic equipment.But its formula contains: trichloroethane, carbon tetrachloride and other toxic solvents, and has the defects such as complex preparation and construction.CN111826238A discloses a kind of precision instrument cleaning agent and preparation method of aerosol type, cleaning agent its formula includes: environmentally friendly solvent 75.0-90.0 parts, surfactant 0.01-1.0, cosolvent 1.0-10.0 parts, propellant 5.0~10.0 parts by weight.Cleaning agent product is safe to use, no flash point, non-combustible, ODP is zero, GWP value is low, meets environmental protection requirements, but the formula does not consider the influence of possible rust on instruments during cleaning.CN101413129A discloses a kind of antirust metal cleaning agent, cleaning agent formula is prepared according to weight percentage and includes: caustic soda 0~10%, sodium silicate 8~15%, ethanolamine 5~15%, C11~C15 dibasic oleic acid 1~5%, surfactant 5~10%, the rest is water, but the formula contains environmentally harmful and non-degradable ingredients.Therefore, it is imperative to develop a cleaning agent with the characteristics of charged operation, good cleaning effect, low toxicity, environmental protection, rust prevention and biodegradability.

[0005] The present application aims at the possible insufficient cleaning ability, rust and other situations during the charged cleaning process of precision instruments, and compounding a kind of precision instrument high-efficiency cleaning agent with strong cleaning ability, high product safety performance, rust prevention, low toxicity, environmental protection and biodegradability.In the selection of cleaning formula, components with high boiling point, difficult to volatilize, strong solubility, low toxicity and environmental protection are used as much as possible to avoid the use of components containing halogen, phosphorus and other components that may cause water and environmental pollution;In the selection of corrosion inhibitor, since inorganic oxide film corrosion inhibitor and inorganic deposition film corrosion inhibitor both form a film on the metal surface by using inorganic metal ions, which adheres to the metal surface to achieve the effect of corrosion inhibition, but if the metal ion density is too small or the pH value changes, micro-batteries may be formed at the damage site of the metal surface, therefore an organic adsorption film corrosion inhibitor is selected.
