Problems solved by technology

[0003] Most of the drawing oils currently used are pure oil-based products, and these products have defects of varying degrees, such as large production consumption, uneven coating, easy to produce oil pockets, cannot be welded with oil, and poor working conditions , the environment is dirty, it is difficult to clean with water, the exhaust hood is often caught on fire, and some rust resistance is not good enough
In recent years, the emulsion drawing oil of oil and water has been developed, and its production and application on different stamping parts of automobiles has not completely changed the above shortcomings.

Embodiment 1

[0032] Raw materials and weight percentages used are as follows:

[0033] Mol ratio is 10%~15% of water-containing 20% ​​triethanolamine borate transparent liquid of 1:1, and Mol ratio is 40%-50% of water-containing 20% ​​fatty acid triethanolamine salt transparent liquid of 1:2, and Mol ratio is 1: 1. Water-containing 10% triethanolamine oleate transparent liquid is 25% to 30%, and deionized water is 10% to 15%.

[0034] After the above-mentioned materials required for compounding are produced first, their respective weight percentages are selected within the above-mentioned ratio range according to the drawing oil viscosity requirements for shallow stretching and stamping, and finally normalized.

[0035] The production method is as follows:

[0036] a. First, add a calculated raw material such as boric acid into the reaction kettle according to the molar ratio, heat it to 50°C-80°C to melt it, then add the calculated 20% water, and slowly add another raw material under slo...

Embodiment 2

[0040] The production method is the same as Example 1, except that the raw materials used and the percentage by weight are as follows: the Mol ratio is 10% to 15% of the water-containing 10% triethanolamine borate transparent liquid of 1: 1, and the Mol ratio is 1: 2 of the water-containing 10% fatty acid three 40%-50% ethanolamine salt transparent liquid, 25%-30% aqueous 10% diethanolamine oleate transparent liquid with a Mol ratio of 1:1, and 10%-15% deionized water.

Embodiment 3

[0042]The production method is the same as in Example 1, except that the raw materials used and the percentage by weight are as follows: a 10% to 15% diethanolamine borate transparent solution containing 5% water with a Mol ratio of 1:1, and a 10% water-containing solution with a Mol ratio of 2:1. 40%-50% of triethanolamine fatty acid salt transparent liquid, 25%-30% of water-containing 5% diethanolamine oleate transparent liquid with a Mol ratio of 1:1, and 10%-15% of deionized water.

[0043] The stock solutions of the products of Example 1, Example 2 and Example 3 of the present invention can be directly used as stock solutions for stamping and stretching of steel plates.

Abstract

The invention relates to a producing method of water-soluble drawing oil for stamping carbon steel sheets, belongs to the field of organic chemical synthetic new products, and particularly relates to the producing method of water-soluble drawing oil for stamping automobile steel sheets. The production method of completely-transparent water-soluble drawing oil for stamping the automobile steel sheets comprises two steps: producing required raw materials through chemical synthesis and compounding the raw materials to produce the final product. A simple formula, high-performance materials and comprehensive consideration are adopted to develop the drawing oil meeting production and environment requirements. According to the drawing oil, organic amine fatty acid salt is utilized as main components, and water is utilized as diluent without adding any other auxiliaries. Pure water base drawing oil products have the advantages of saving energy, retarding flame, having good cooling performance(specific heat of water is 3-5 times that of oil, and vaporization latent heat of water is 9-15 times that of oil. ) and being capable of being directly washed through tap water, low in cost, safe and environment-friendly. In addition, waste of the pure water base drawing oil product can be naturally degraded.

Description

technical field [0001] The invention belongs to the field of new organic chemical synthesis products, and in particular relates to a production method of drawing oil for stamping automobile steel plates. Background technique [0002] In the production of auto parts, a considerable part is formed by stamping after shearing carbon steel sheets. The stamping parts of CA1092 trucks account for more than 30% of the weight of the whole vehicle, and the total weight of stamping parts of CA7220 Xiaohongqi or Audi100 cars accounts for more than 30% of the weight of the whole vehicle. More than 50% of the weight, and some models account for more than 60-70%. During the processing of these stamping parts, due to the plastic deformation of the plate between the punch and the die, during the entire plastic deformation process, due to the friction and uneven force between the mold and the metal, the workpiece and the mold heat up, resulting in roughening of the workpiece. And cracking an...
