Abstract

The invention relates to the daily chemical field, in particular to a cleaning agent. A metal cleaning agent comprises the following components in percentage by weight: 2-8% of a zwitterionic surfactant; 5-10% of a non-ionic surfactant; 2-5% of a corrosion inhibitor; 0-1.5% of a defoaming agent; 10-20% of sodium phosphate; 3-8% of sodium tripolyphosphate; 5-12% of trisodium phosphate; and a solvent added to 100%. By taking a mixture of novel organic surfactants, fatty alcohol polyoxyethylene ether and fatty acid methyl ester ethoxylate as an emulsifier for compounding, the metal cleaning agent provided by the invention is endowed with great dispersing and anti-staining capabilities, and makes up the deficiency of the prior art. In a normal-temperature state, the metal cleaning agent has a high dissolving capacity for various oils, and can dissolve heavy oils and age deteriorated oils. The metal cleaning agent can remove saponifiable oil stains as well as unsaponifiable oils, and can prevent oil stains removed from a workpiece from staining a metal surface.

Description

A kind of metal cleaner

Technical field

The present invention relates to household chemicals field, be specifically related to a kind of clean-out system.

Background technology

Current metallic surface oil-removing cleaning agent, be much that the use temperature of requirement clean-out system is higher, such energy dissipation is serious.And can normal temperature use metallic surface oil-removing cleaning agent, there is dispersing property difference, the oil removing time, generally more than 30 minutes, greasy dirt is easily counter to stain in metallic surface, and cleaning performance is also imperfect.

Summary of the invention

Technical problem to be solved by this invention is to provide a kind of metal cleaner.

Technical problem to be solved by this invention is achieved by the following technical programs:

A kind of metal cleaner, the component containing, for example lower weight percent:

Zwitterionics 2 ~ 8%; Nonionic surface active agent 5 ~ 10%; Inhibiter 2 ~ 5%; Defoamer 0 ~ 1.5%; Sodium phosphate 10 ~ 20%; Tripoly phosphate sodium STPP 3 ~ 8%; Tertiary sodium phosphate 5 ~ 12%; And by solvent makeup to 100%.

Further, described zwitterionics is organic silicon surfactant; Wherein, described organic silicon surfactant structural formula is as follows:

, wherein, R ₁for , X is ; In structural formula, n=60 ~ 80, a=3 ~ 6, b=3 ~ 6.

Further, described organic silicon surfactant is synthesized by following steps:

(1) octamethylcyclotetrasiloxane and the vitriol oil is added in a reservoir, tetramethyl-dihydro base sily oxide is added after intensification, constant temperature stirs 4h, add soda ash to neutralize, filter, filtrate joining is equipped with nitrogen protection, in the container of condensing reflux and agitation condition, then polyoxy polyoxyethylene base epoxy group(ing) end capped polyether is added, stirring is warming up to 80 DEG C, add Platinic chloride, continue again to be warming up to 120 DEG C of reaction 5h, then after being cooled to 80 DEG C, slowly drip the mixture of diethanolamine and Virahol simultaneously, back flow reaction 6h, stop stirring, constant temperature 1h, revolve and steam except desolventizing, obtain pale yellow transparent oily liquids,

(2) in the container that nitrogen protection, condensing reflux and agitation condition are housed, add pale yellow transparent oily liquids and the Virahol of step (1) gained; be warming up to 80 DEG C; by 3; 4-dihydroxyphenyl propionic acid sodium is slowly added dropwise in flask; reaction backflow 6h, except desolventizing after reaction terminates, obtains thick product; thick product through process, finally obtains organic silicon surfactant again.

The organic silicon surfactant of synthesizing new of the present invention, can improve the dissolving power of scavenging solution to various grease.

Further, described nonionic surface active agent is the mixture of fatty alcohol-polyoxyethylene ether and fatty acid methyl ester ethoxylate.The present invention is in order to solve the dispersion problem of novel organic silicon surfactant at ether solvent, take the mixture of fatty alcohol-polyoxyethylene ether and fatty acid methyl ester ethoxylate as emulsifying agent to improve its dispersion problem, thus effectively improve the washing power of clean-out system.

Further, described inhibiter is benzotriazole.

The conventional defoamer of the present invention's defoamer the art used can realize the present invention.

Further, solvent for use of the present invention is that the ether solvent that the art is commonly used can realize the present invention, as: at least one in butyl, diethylene glycol dimethyl ether, dipropylene, dipropylene glycol methyl ether, ethylene glycol monomethyl ether, propylene glycol monomethyl ether, butyl glycol ether and propandiol butyl ether.

Further, the weight percent of this clean-out system is preferably:

Organic silicon surfactant 2 ~ 8%; Fatty alcohol-polyoxyethylene ether 2 ~ 4%; Fatty acid methyl ester ethoxylate 3 ~ 5%; Benzotriazole 2 ~ 5%; Defoamer 0 ~ 1.5%; Sodium phosphate 10 ~ 20%; Tripoly phosphate sodium STPP 3 ~ 8%; Tertiary sodium phosphate 5 ~ 12%; And by solvent makeup to 100%.

The present invention has following beneficial effect:

Metal cleaner of the present invention relies on novel organic surface active agent and fatty alcohol-polyoxyethylene ether, the mixture of fatty acid methyl ester ethoxylate makes it have powerful dispersion and soil resistant ability as the mode that emulsifying agent is composite, compensate for the defect of prior art.Under normal temperature state, there is very strong dissolving power to each quasi-grease, can mink cell focus be dissolved, aged deterioration grease.No matter be that saponifiability greasy dirt or non-soap voltinism grease all can be removed, can prevent that the greasy dirt of cleaning workpiece is counter to stain in metallic surface.
