Embodiment 1

[0046] Weigh each raw material according to the following mass fractions: 1% Surfactin, 2% rhamnolipid, 3% polyaspartic acid, 3% lysine, 3% sodium oxalate, 0.2% defoamer, and the balance is deionized water . The rhamnolipid is a mixture obtained from the fermentation of Pseudomonas, containing 50% wt of monosaccharide ring rhamnolipid, 20% wt of disaccharide ring rhamnolipid, and the molecular weight of polyaspartic acid is 1000.

[0047] According to the mass content of each substance, put deionized water, lysine and surfactant peptide Surfactin into the reaction kettle, mix and dissolve at 50°C for 3 hours, then add rhamnolipid, sodium polyaspartate and Sodium oxalate is placed in the reaction kettle, stirred at 50°C for 3 hours, so that the raw materials in the reaction kettle are mixed evenly, and finally the defoamer is added to obtain an environmentally friendly cleaning agent.

Embodiment 2

[0049] Weigh each raw material according to the following mass fraction: Surfactin 2%, rhamnolipid 4%, polyaspartic acid 1%, lysine 5%, sodium oxalate 5%, defoamer 0.5%, and the balance is deionized water . The rhamnolipid is a mixture obtained by fermentation of Burkholderia, containing 60% wt of monosaccharide ring rhamnolipid, 25% wt of disaccharide ring rhamnolipid, and the molecular weight of polyaspartic acid is 2000.

[0050] According to the mass content of each substance, put deionized water, lysine and surfactant peptide Surfactin into the reaction kettle, mix and dissolve at 55°C for 4 hours, then add rhamnolipid, sodium polyaspartate and Sodium oxalate is placed in the reaction kettle, stirred at 55°C for 2 hours, so that the raw materials in the reaction kettle are evenly mixed, and an environmentally friendly cleaning agent is obtained.

Embodiment 3

[0052] The raw materials were weighed according to the following mass fractions: 1% Surfactin, 5% rhamnolipid, 2% polyaspartic acid, 3% lysine, 4% sodium oxalate, 0.1% defoamer, and the balance was deionized water . The rhamnolipid is a mixture obtained by fermentation of Pseudomonas, containing 55% wt of monosaccharide ring rhamnolipid, 30% wt of disaccharide ring rhamnolipid, and the molecular weight of polyaspartic acid is 4000.

[0053] According to the mass content of each substance, put deionized water, lysine and surfactant peptide Surfactin into the reaction kettle, mix and dissolve at 60°C for 2 hours, then add rhamnolipid, sodium polyaspartate and Sodium oxalate is placed in the reaction kettle, stirred at 60°C for 2 hours, so that the raw materials in the reaction kettle are evenly mixed, and an environmentally friendly cleaning agent is obtained.

Abstract

The invention discloses a metal processing product surface cleaning agent composition and its preparation and use method. The cleaning agent composition contains 1%-5% of surface active peptide and 2%-5% of rhamnolipid biosurfactant , sodium polyaspartate 1%~3%, lysine 1%~5%, sodium oxalate 3%~6%, defoamer 0.1%~1%, and the balance is water. The main component of the cleaning agent for metal products proposed by the present invention is a biodegradable biosurfactant, which does not contain carcinogens such as phosphorus and nitrite, and does not contain APED surfactants. The cleaning effect is excellent and the cleaning time is short , which is convenient for automatic cleaning; the cleaning agent is alkaline and has negligible corrosion on the surface of stainless steel products, so it can be used safely; the product is a water-soluble liquid, and the waste liquid after cleaning is easy to treat and discharge, and the surfactant component is biodegradable and will not polluted environment.

Description

technical field [0001] The invention belongs to the field of industrial cleaning and metal processing surface treatment, and relates to an environmentally friendly water-based cleaning agent composition, in particular to a biosurfactant composition for cleaning the surface of metal processing products. [0002] technical background [0003] In the manufacturing process of mechanical parts, in order to make the processing process smooth and efficient, it is often necessary to use a large amount of oily medium for lubrication, cooling or anti-rust treatment, so more or less oily medium will remain on the surface of metal parts, including Cutting oil, quenching oil, rolling oil, anti-rust oil, etc. If these residual oily media cannot be cleaned efficiently, it will not only affect the subsequent processing procedures, but also have an adverse effect on product quality. Metal cleaning is an essential process link in the process of processing, assembling, storing and repairing me...
