Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of thread rolling, in particular to a water-based thread rolling liquid suitable for a thread rolling machine and a preparation method thereof. BACKGROUND

[0002] A thread rolling machine is a device for processing threads on the outer part of a cylindrical or tubular metal piece, which can be divided into double-shaft and triple-shaft types. Specifically, thread rolling is a process in which a thread rolling die roller is installed on a thread rolling machine shaft, a workpiece is placed in the gap between the die rollers, and the thread rolling machine shafts are driven to rotate while being pulled close to each other by a hydraulic method, so that the workpiece clamped between the die roller gaps is rotated due to pressure to form threads on the surface. Since a large amount of heat is generated during thread rolling, a lubricating medium must be used. The lubricating medium provides lubrication and heat dissipation functions to ensure processing accuracy and die life. As is known, lubrication can reduce wear and heat generation, so a lubricating medium must be used to achieve the above purposes. In the prior art, low-viscosity media such as machine oil and diesel oil are commonly used for thread rolling. Although machine oil and diesel oil have good heat dissipation ability due to their low viscosity, they are also volatile due to their low viscosity, making it easier to absorb heat, thereby achieving better heat dissipation of the thread die. However, as is known, the temperature is very high during processing, which makes it easy for machine oil or diesel oil to produce oil smoke during use, and because diesel oil has a flash point lower than 90℃, it is a dangerous product that can easily cause a fire hazard. Most importantly, machine oil and diesel oil have poor wear resistance, which can easily cause die wear. SUMMARY

[0003] Therefore, the present application provides a water-based thread rolling liquid suitable for a thread rolling machine and a preparation method thereof, which can solve the above problems.

DETAILED DESCRIPTION

[0019] The specific embodiments of the application are further described below. It should be understood that the description of the embodiments of the application herein is not intended to limit the protection scope of the application.

[0020] The water-based rolling liquid for the rolling machine provided by the application is composed of water, diethylene glycol amine, triethanolamine, triethanolamine borate, 2-amino-2-methyl-1-propanol, 2-methyl-2-methylamino-1-propanol, disodium ethylenediaminetetraacetate, 2,4,6-tris(amino hexanoic acid)-1,3,5-triazine, 2-methyl-3(2H)-isothiazolinone, 1,2-benzisothiazolyl-3(2H)-ketone, polydichloroethyl ether tetramethyl ethylenediamine, polyoxyethylene polyoxypropylene, polyalkylene glycol monobutyl ether, 1,2,3-benzotriazole, and phosphate ester.

[0021] In the water-based rolling liquid, the water is 45.0-60.0 parts, the diethylene glycol amine is 1.0-3.0 parts, the triethanolamine is 10.0-15.0 parts, the triethanolamine borate is 3.0-5.0 parts, the 2-amino-2-methyl-1-propanol is 0.1-0.5 parts, the 2-methyl-2-methylamino-1-propanol is 0.03-0.05 parts, the disodium ethylenediaminetetraacetate is 1.0-2.5 parts, the 2,4,6-tris(amino hexanoic acid)-1,3,5-triazine is 4.0-6.0 parts, the 2-methyl-3(2H)-isothiazolinone is 0.01-0.03 parts, the 1,2-benzisothiazolyl-3(2H)-ketone is 0.01-0.05 parts, the polydichloroethyl ether tetramethyl ethylenediamine is 0.01-0.05 parts, the polyoxyethylene polyoxypropylene is 10.0-20.0 parts, the polyalkylene glycol monobutyl ether is 3.0-5.5 parts, the 1,2,3-benzotriazole is 0.01-0.05 parts, and the phosphate ester is 1.0-3.5 parts, all based on 100 parts. It can be understood that each component above should be the prior art, and thus the properties and preparation methods of each component above should also be the prior art, which will not be described herein.

[0022] Since the water-based thread rolling fluid is a water-based product, and water-based products can breed microorganisms, the water-based product is made into a weak base system with various amines, i.e., diethanolamine and triethanolamine, so that the water-based product can reduce microbial activity and also has other functions of stabilizing water.

[0023] In addition, since 2,4,6-tris(aminohexanoic acid)-1,3,5-triazine needs to be reacted in a weak base aqueous solution to become a compound with rust prevention function, the diethanolamine and triethanolamine are also needed to make a weak base system. After 2,4,6-tris(aminohexanoic acid)-1,3,5-triazine is reacted in the weak base aqueous solution, a compound with rust prevention function is formed, so that the rolled screw can be prevented from being oxidized, achieving the function of preventing rust.

[0024] Calcium and magnesium ions are prone to form water stains on the surface of the processed metal, resulting in poor visual finish and easily accelerating the occurrence of rust, so the formula needs to have chelation function to prevent calcium and magnesium ions from forming water stains. In addition, since water-based products are prone to cause microbial breeding problems during use due to improper operation or the entry of foreign objects, the product needs to have antibacterial function to extend the service life of the product. Therefore, by adding disodium ethylenediaminetetraacetate, the metal cations in the water-based thread rolling fluid can be chelated, and since disodium ethylenediaminetetraacetate has the property of damaging the cell membrane of bacteria, it is toxic to bacteria, so by adding disodium ethylenediaminetetraacetate, the growth of bacteria can be slowed down, thereby achieving the functions of preventing water stains and inhibiting bacteria, and further avoiding the formation of water stains on the surface of the processed metal and extending the service life of the water-based thread rolling fluid. Since water-based products are prone to cause microbial breeding problems during use due to improper operation or the entry of foreign objects, microorganisms can make the water-based thread rolling fluid acidic, so the product needs to have antibacterial function to extend the service life of the product. Because the heterocyclic active part of isothiazolinone can block the bond between DNA and protein of bacteria or algae when it contacts them, they cannot reproduce, so by adding 2-methyl-3(2H)-isothiazolinone and 1,2-benzisothiazolyl-3(2H)-ketone, respectively, to inhibit bacteria and mold, the service life of the water-based thread rolling fluid can be extended.

[0025] Since the aqueous product is prone to cause microbial breeding problems due to improper operation or foreign matter entering during use, the establishment of antibacterial function in the product can prolong the service life of the product. Therefore, when the pH is maintained at weak alkaline, the water body has good biological stability and bacteria are not easy to breed. In addition, the small residues after metal processing are easy to float on the liquid surface, and the cationic sedimentation can ensure the cleanliness of the liquid surface. The metal residues after sedimentation will accumulate at the bottom of the pool, and the liquid pump is not easy to extract metal debris, which can prevent damage to the liquid pump. In order to achieve the above purposes, by adding the polydichloroethyl ether tetramethyl ethylenediamine, the antibacterial and cationic sedimentation functions can be achieved. Polydichloroethyl ether tetramethyl ethylenediamine can affect the permeability of microbial cell wall, and microorganisms cannot exchange the required nutrients through the cell wall, so they will die, thereby reducing the breeding of microorganisms and inhibiting the generation of bacteria. The pH of 1% aqueous solution of polydichloroethyl ether tetramethyl ethylenediamine; polydichloroethyl ether tetramethyl ethylenediamine is a quaternary ammonium salt, and the general formula of quaternary ammonium salt is R4NX, X- is a negatively charged ion formed by replacing the four hydrogen atoms of the ammonium ion with hydrocarbon groups, so it can attract positively charged metal ions through X-. Since the metal processing is mostly iron, when polydichloroethyl ether tetramethyl ethylenediamine continuously absorbs iron ions for a long time, it can form large particle groups and precipitate at the bottom of the water tank, thereby achieving the function of cationic sedimentation.

[0026] The polyoxyethylene polyoxypropylene and the polyalkylene glycol monobutyl ether are main lubricants. By setting the blending ratio, the water-based thread rolling fluid has good lubricating performance and can improve the heat conduction performance of the water-based thread rolling fluid. Specifically, the polyoxyethylene polyoxypropylene is 10.0-20.0 parts. If the polyoxyethylene polyoxypropylene is less than 10 parts, the lubricating performance of the water-based thread rolling fluid will be greatly reduced. If the polyoxyethylene polyoxypropylene is more than 20 parts, the concentration of the polyoxyethylene polyoxypropylene will be too high, which may cause the equipment using the water-based thread rolling fluid to be stripped of paint, because the polyoxyethylene polyoxypropylene has a certain solubility. Of course, whether it will be stripped of paint still depends on the paint components on the equipment. The polyalkylene glycol monobutyl ether is 3.0-5.5 parts. If the polyalkylene glycol monobutyl ether is less than 3.0 parts, the lubricating performance of the water-based thread rolling fluid will be significantly reduced. If it is more than 5.5 parts, the polyalkylene glycol monobutyl ether cannot quickly dissolve into the water-based thread rolling fluid when it is dissolved in reverse, but is attached to the workpiece, which not only affects the subsequent process, but also requires cleaning, increasing the cost and possibly polluting the environment. The reverse solubility refers to the solubility being inversely proportional to the temperature. The polyalkylene glycol monobutyl ether has good reverse solubility. It can be well dissolved in water at room temperature, and will be precipitated from the water when the water temperature is increased. The polyalkylene glycol monobutyl ether is a viscous liquid at room temperature, and can increase the viscosity of water when dissolved in water. When the roller die and the workpiece generate heat during the thread rolling process, the polyalkylene glycol monobutyl ether can be dissolved in reverse in the water-based thread rolling fluid, coated on the surface of the roller die and the workpiece in the friction pair, and play a lubricating role, thereby reducing wear. When the heat of the friction pair is taken away by the water-based product, the substance is dissolved in the water-based thread rolling fluid.

[0027] Since the metal processing machine parts may contain copper, by adding the 1,2,3-benzotriazole, copper oxidation can be prevented.

[0028] Since the metal processing machine parts may contain aluminum, by adding the phosphate ester, aluminum oxidation can be prevented. At the same time, the phosphate ester can achieve the effects of smoothing the metal surface, increasing the extreme pressure lubrication at a certain temperature, such as 380-800°C. That is, the phosphorus compound can form a thin film of iron phosphate on the surface of the metal at 380-800°C, and the film has a lubricating effect, thereby reducing the probability of dry friction of the metal.

[0029] In addition, the water-based thread rolling fluid replaces the oil-based metal processing fluid, and has the characteristics of no oil smoke, no combustion, good heat dissipation, wear resistance, and high pressure resistance.

[0030] The application also provides a preparation method of the water-based thread rolling liquid suitable for a thread rolling machine, which comprises the following steps:

[0031] STEP 101: 45.0-60.0 parts of water, 1.0-3.0 parts of diglycolamine, 10.0-15.0 parts of triethanolamine, 3.0-5.0 parts of triethanolamine borate, 0.03-0.05 parts of 2-amino-2-methyl-1-propanol, 0.01-0.03 parts of 2-methyl-2-methylamino-1-propanol and 1.0-2.5 parts of disodium ethylenediaminetetraacetate are put into a reaction kettle to be mixed into an aqueous solution with a pH value of 9.0-10.0, and it is determined that the powders are completely dissolved into a uniform lye;

[0032] STEP 102: 4.0-6.0 parts of powdered 2,4,6-tris(aminohexanoyl)-1,3,5-triazine are put into the reaction kettle to be neutralized with the lye in the previous step to form a triacid rust inhibitor, and the 2,4,6-tris(aminohexanoyl)-1,3,5-triazine is completely dissolved;

[0033] STEP 103: 0.01-0.03 parts of 2-methyl-3(2H)-isothiazolinone and 0.01-0.05 parts of 1,2-benzisothiazolyl-3(2H)-ketone are put into the reaction kettle to form a liquid with bacteriostatic function;

[0034] STEP 104: 0.3-0.8 parts of polydichloroethyl ether tetramethyl ethylenediamine are put in to form a function of precipitating cations;

[0035] STEP 105: 10.0-20.0 parts of polyoxyethylene polyoxypropylene are put in to make the liquid have lubricating and inverse solubility characteristics;

[0036] STEP 106: 0.01-0.05 parts of 1,2,3-benzotriazole are added and completely dissolved to make the liquid have the function of inhibiting the oxidation of copper ions;

[0037] STEP 107: 1.0-3.5 parts of phosphate ester are added to make the liquid have the function of preventing aluminum oxidation, and finally the water-based thread rolling liquid suitable for a thread rolling machine is prepared.

[0038] In STEP 101, the pH value must be set between 9 and 10. If the pH value is less than 9, the 2,4,6-tris(aminohexanoyl)-1,3,5-triazine in STEP 102 will be dissolved very slowly, affecting the use of the product. If the pH value is greater than 10, it is easy to cause skin allergy of the operator during operation, and a high pH value may also cause damage to the sealing ring of the production equipment, which is not conducive to safe use.

[0039] In step STEP 102, the formed triacid rust preventive is a carboxylic acid amine salt with carboxylate.

[0040] In step STEP 104, the formed precipitable cation can precipitate the tiny metal residue formed after the processing of the metal floating on the liquid surface to ensure the liquid surface is clean, and the precipitated metal residue will be accumulated at the bottom of the pool, so that the metal debris can not be easily pumped by the liquid pump, thereby preventing the processing equipment from being damaged.
