Abstract

The invention discloses an environment-friendly flame-retardant solvent cleaner. The solvent cleaner comprises a main cleaning agent, an azeotropic solvent and an auxiliary cleaning agent, wherein the main cleaning agent is any one of or a mixture of two of 1,1,2,2,3-pentafluoropropane, perfluoroether and propyl bromide; the azeotropic solvent is a mixture of any two of absolute ethyl alcohol, isopropyl alcohol and n-butyl alcohol; the auxiliary cleaning agent is any one of or a mixture of two of ethylene glycol monomethyl ether, ethylene glycol monoethyl ether and diethylene glycol monomethyl ether; the cleaner comprises, in percentage by weight, 50%-65% of the main cleaning agent, 10%-25% of the azeotropic solvent and 15%-30% of the auxiliary cleaning agent. The invention further provides a preparation method of the environment-friendly flame-retardant solvent cleaner. The solvent cleaner has high cleaning capability and good cleaning effect, is flame-retardant, non-toxic and odorless, cannot pollute the environment or the atmosphere and is a real flame-retardant and environment-friendly industrial cleaner.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to organic compounds, in particular to solvents, in particular to an environment-friendly flame-retardant solvent cleaning agent and a preparation method thereof. Background technique [0002] Environmental protection and product safety are the two major themes of product use in the world today, and have been valued by more and more countries.
