Problems solved by technology

However, this type of tapping fluid in the prior art with water as the dispersion medium has poor lubricity and rust resistance, and some products also have disadvantages such as not being environmentally friendly and affecting human health.
For example, some products add (C10-C13) short-chain chlorinated paraffins and sodium nitrite to increase lubricity and rust resistance. Chlorinated paraffins have better lubricity, but due to the unstable pH value of such substances, use A large amount of free chlorine will be produced during the process, which will corrode the machine tool taps, and it is easy to decompose during the processing process. The released hydrogen chloride gas will have a certain impact on the liver and kidneys of the human body. Although sodium nitrite has good rust resistance, but is actually a potential carcinogen
[0005] To sum up, the common tapping fluid currently on the market has the technical problem of unstable pH value, which affects the performance of the tapping fluid, and the tapping fluid also has short service life, difficult discharge, not environmentally friendly and affects the human body. Health and other issues

Abstract

The invention discloses a method for preparing an environment-friendly tapping fluid for an automobile air conditioning filter cover plate, comprising the following steps: S10, providing the following raw materials: antirust agent A, antirust agent B, metal corrosion inhibitor, lubricant, Coupling agent and deionized water; S20, add antirust agent A and metal corrosion inhibitor into deionized water, stir, heat up to 45-55°C and keep warm to prepare the first mixture; S30, add antirust agent B to the second In a mixture, stir and heat up to 75-85°C to prepare a second mixture; S40, add lubricant and coupling agent to the second mixture to prepare an environment-friendly tapping fluid; wherein, the antirust agent A is boric acid, Decane dibasic acid, undecane dibasic acid, dodecane dibasic acid, tribasic acid, or a mixture of at least two, rust inhibitor B is monoethanolamine, triethanolamine, 2‑amino‑2 One or a mixture of at least two of -methyl-1-propanol. The pH value of the environment-friendly tapping fluid prepared by the preparation method of the invention is more stable, and the comprehensive use performance is better.

Description

technical field [0001] The invention belongs to the field of lubricating materials, and in particular relates to a method for preparing an environment-friendly tapping fluid for an automobile air-conditioning filter cover plate and the environment-friendly tapping fluid prepared by the method. Background technique [0002] In metal cold processing, in order to ensure the processing accuracy of the workpiece and prolong the service life of the cutting tool, it is necessary to use lubricant materials with the functions of lubrication, cleaning, cooling and antirust. [0003] At present, most of the tapping fluids on the market for machining air conditioner filter cover threads are emulsified oily emulsions. This oily emulsion can meet the cooling and lubricating effects required for workpiece processing, but the working fluid is easy to get dirty and needs to be replaced. The cycle is short, the comprehensive cost is high, and the replaced waste liquid contains a large amount ...
