Abstract

The invention relates to a foamless detergent which is aliphatic alcohol polyether synthesized by an external recycle unit and which is composed of aliphatic alcohol, epoxy ethane and propylene oxide. By the employment of the detergent of the invention, various oils and resembling oil materials can be easily removed from a plurality of adsorbates. The detergent substitutes for normal series products of ODS and APEO which are harmful to human environment, and has the advantages of toxic-free property and environment preservation. The invention has outstanding properties, including humectation, emulsification, dispersion, solubilization and the like, and thereby the invention is an environment-friendly detergent which is high in efficiency, acid-free, high in wetting property and high in detergency.

Description

Technical field: [0001] The invention relates to a non-foaming detergent and a preparation method thereof. The cleaning agent is a fatty alcohol polyether synthesized from fatty alcohol, ethylene oxide, and propylene oxide using external circulation equipment. It belongs to the surfactant type cleaning agent. It is efficient, environmentally friendly, easy to biodegrade, and has no foam during cleaning. produce characteristics. Background technique: [0002] As we all know, the destruction of the ozone layer and global warming have become one of the most serious environmental problems facing human society today. The international community has formulated a series of international conventions on the protection of the ozone layer. my country joined the "Vienna Convention for the Protection of the Ozone Layer" in 1989 and signed the "Montreal Protocol on Substances that Deplete the Ozone Layer" in 1991. Since 1995, China's cleaning industry, as one of the ODS (ozone-depleting...
