Abstract

The invention provides an aerosol type precise instrument cleaning agent and a preparation method. The formula of the aerosol type precise instrument cleaning agent comprises the following componentsin parts by weight: 75.0-90.0 parts of an environment-friendly solvent, 0.01-1.0 part of a surfactant, 1.0-10.0 parts of a cosolvent and 5.0-10.0 parts of a propellant. According to the invention, thecleaning agent for the precise instrument has the following beneficial effects that 1, the cleaning agent is excellent in performance, safe and reliable, and can quickly remove dust, oil stains, moisture and the like of the precise instrument under the condition of no power failure; 2, the construction operation is flexible, simple and convenient, and the product safety is high; 3, the cleaning agent product is safe to use, free of flash point, non-combustible, zero in ODP and low in GWP value, and meets the environmental protection requirement; and 4, the volatilization speed is moderate, the ice crystal effect and the condensation phenomenon are avoided in the cleaning process, the surface insulation value of the equipment is not obviously reduced, and the equipment is not corroded anddamaged. The invention further discloses a preparation method of the precise instrument cleaning agent.

Description

technical field [0001] The invention relates to the technical field of aerosol cleaning agents, in particular to an aerosol-type precision instrument cleaning agent and a preparation method thereof. Background technique [0002] With the electronicization of industrial equipment and the development of control automation, the production and use of electronic, electrical and other precision instruments and equipment have grown rapidly. The urgent demand for live cleaning for the maintenance of precision instruments such as electronics and electrical equipment has brought great opportunities for the development of the live cleaning industry, especially the demand for safe operation and superior cleaning effects has forced researchers to continuously study better alternatives to cleaning agents. At present, the charged cleaning agent for electrical equipment and its preparation method mainly use solvents, cosolvents and surfactants to solve the problem of cleaning electrical equ...
