Embodiment 1

[0030] Use a 150L reactor to produce 100 kg of water-soluble drawing oil for heavy drawing, and the usage requirement is 30 o C, the viscosity is 1500mpa s as an example:

[0031] According to the requirements of the equipment used, determine the operating environment temperature 30 o C and viscosity 1500mpa·s, such as figure 1 As shown, check a=1.61, b=-0.59, and get the specific model , , to calculate the feed ratio =0.89, the quality sum of water and ethanolamine borate ester is equal to the quality of ethanolamine fatty acid salt. The compound mass ratio is ethanolamine fatty acid salt:ethanolamine borate ester:water=1:0.89:0.11. Therefore, the feeding ratio is determined as ethanolamine fatty acid salt=50 kg, ethanolamine borate=44.5 kg, water=5.5 kg.

Embodiment 2

[0033] Ambient temperature 20 o C, the viscosity requirement is 600 mpa s, for moderate stretching, such as figure 2 As shown, check a=1.84, b=-0.80, and get the specific model , , to calculate the feed ratio =0.74, and the sum of the mass of ethanolamine borate is equal to the mass of ethanolamine fatty acid salt. The compound mass ratio is ethanolamine fatty acid salt:ethanolamine borate:water=1:0.74:0.26. Therefore, the feeding ratio is determined as ethanolamine fatty acid salt=50 kg, ethanolamine borate ester=37 kg, water=13 kg.

Embodiment 3

[0035] Ambient temperature 10 o C, the viscosity requirement is 200 mpa s, for shallow stretching, such as figure 2 As shown, check a=1.31, b=-0.46, and get the specific model , , to calculate the feed ratio =0.46, the mass sum of water and ethanolamine borate is equal to the mass of ethanolamine fatty acid salt. The compound mass ratio is ethanolamine fatty acid salt:ethanolamine borate:water=1:0.46:0.52. Therefore, the feeding ratio is determined as ethanolamine fatty acid salt=50 kg, ethanolamine borate ester=23 kg, water=27 kg.

Abstract

The invention discloses a production method and a supporting production model for new-generation complete-water-soluble drawing oil, belongs to the field of novel fine chemical engineering products, and especially relates to production and application of sheet stamping parts in the fields of automobiles and the like. According to different use methods, such as smearing and the like, the drawing oil needs to blend according to different viscosities. According to the technical scheme, three substances, ethanol amine borate (A), ethanol amine fatty acid salt (B) and water (C), which are self-synthesized, are subjected to scale-up compounding, wherein the mass ratio of A:B:C is 1:1-0.2:1-0.1. A corresponding scale-up production viscosity model is modified ASTM model. With the viscosity at environment temperature as index and B and C as regulation variables, under the scale-up production, addition amount ratio of scale-up production is calculated through the model. Compared with an oil-based product in the prior art, the drawing oil has better cooling property, lubricity and extreme pressure resistance, can save a deoiling process for stamping parts, can be washed by tap water, is flame-retarding, is safe and environment-friendly and is suitable for heavy tensile application on complex parts.

Description

technical field [0001] The invention relates to a pilot-scale production method and an enlarged model of a completely water-soluble drawing oil for carbon steel sheet stamping. Background technique [0002] As a kind of process oil, drawing oil plays a very important role in the stamping process of sheet metal, and has the properties of lubrication, anti-extreme pressure, cooling, and anti-rust. At present, the drawing oils used in the mechanical stamping of metal sheets on the market are all oil-based products. Its disadvantages are: stamping products cannot be washed with water, and high-temperature degreasing processes are required; oil-based products have poor cooling performance and are easy to burn; Tensile extreme pressure resistance and insufficient lubricity, etc. Completely water-soluble water-based drawing oil products are a new generation of alternative products, which have the advantages of complete water washability, high extreme pressure resistance, lubricati...
