Embodiment 1

[0011] A water-based metal cleaning agent that is convenient for removing oil from workpieces is composed of the following components by weight: 4.76% of sodium carbonate, 4.07% of sodium borate, 2.53% of sodium hydroxide, 11.54% of triethanolamine oleate, polyoxyethylene fatty alcohol Ether 15.36%, triethanolamine 12.65%, defoamer 0.94%, urea 0.97%, water 47.18%.

Embodiment 2

[0013] A water-based metal cleaning agent that is convenient for removing oil from workpieces is composed of the following components by weight: 4.51% of sodium carbonate, 3.72% of sodium borate, 2.14% of sodium hydroxide, 11.27% of triethanolamine oleate, polyoxyethylene fatty alcohol Ether 14.96%, triethanolamine 11.78%, defoamer 0.81%, urea 0.76%, water 50.05%.

Embodiment 3

[0015] A water-based metal cleaning agent that is convenient for removing oil from workpieces, which is composed of the following components by weight: 4.28% of sodium carbonate, 3.59% of sodium borate, 1.76% of sodium hydroxide, 10.87% of triethanolamine oleate, polyoxyethylene fatty alcohol Ether 14.69%, triethanolamine 11.37%, defoamer 0.72%, urea 0.65%, water 52.07%.

[0016] The defoaming agent is one or more of silicone oil, ethanol or modified siloxane, which can improve the defoaming speed of the cleaning agent without affecting the use effect of the cleaning agent, and has good foam suppression performance and chemical properties. Stable, good diffusivity and permeability, and high safety performance.

[0017] Mix triethanolamine oleate, polyoxyethylene fatty alcohol ether and triethanolamine, fully stir and mix at room temperature and heat to 55-60°C, then cool to obtain a first solution, add sodium carbonate, sodium borate and sodium hydroxide In water, the second ...

Abstract

The invention relates to a water-based metal cleaning agent convenient for workpiece oil removal. The water-based metal cleaning agent comprises, by weight, 4.76% of sodium carbonate, 4.07% of sodium borate, 2.53% of sodium hydroxide, 11.54% of triethanolamine oleate, 15.36% of fatty alcohol polyoxyethylene ether, 12.65% of triethanolamine, 0.94% of an antifoaming agent, 0.97% of urea and 47.18% of water. The water-based metal cleaning agent has good stain removal effects, does not corrode and damage metals, has low alkalinity, has fast cleaning rate, can be rinsed easily, has a long use period and lasting effects, realizes corrosion inhibition and rust prevention of a cleaned workpiece, does not contain harmful elements such as heavy metals and phosphor, reduces environmental pollution and operator diseases, can be used at a normal temperature, can produce less foam, and has simple processes and a low production cost.

Description

technical field [0001] The invention relates to a water-based metal cleaning agent which is convenient for removing oil from workpieces. Background technique [0002] In order to improve the adhesion and corrosion resistance of the existing workpiece during coating or heat treatment, pretreatment such as degreasing and degreasing is required on the metal surface. The dirt on the metal surface includes various acids, alkalis, salts, dust, cutting, hand Sweat, oil stains, etc., not only affect the electroplating and heat treatment of metals, but also cause and accelerate metal corrosion, reduce product quality, and shorten service life. The existing cleaning agents include alkaline cleaning agents and organic solvent cleaning agents for cleaning. There is poor cleaning ability, parts are easy to rust, and organic solvents have strong cleaning ability, but most of them are flammable, volatile, waste energy, cause serious environmental pollution, and have strong irritation to hu...
