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 to

Abstract

The invention discloses a preparation method of environment-friendly type tapping liquid for a cover plate of a filter of an automobile air conditioner. The preparation method comprises the followingsteps: (S10) providing the following raw materials: rustproof agent A, rustproof agent B, metal corrosion inhibitor, lubricant, coupling agent and deionized water; (S20) adding the rustproof agent A and the metal corrosion inhibitor into the deionized water, stirring, rising the temperature to 45-55 DEG C, and then carrying out heat insulation to prepare a first mixture; (S30) adding the rustproofagent B into the first mixture, stirring, rising the temperature to 75-85 DEG C and then carrying out heat insulation to prepare a second mixture; (S40) adding the lubricant and the coupling agent into the second mixture to prepare the environment-friendly type tapping liquid, wherein the rustproof agent A is one or mixture of at least two of boric acid, decyl dibasic acid, undecylenic dibasic acid, dodecenoic dibasic acid and tribasic acid; the rustproof agent B is one or mixture of at least two of monoethanolamine, triethanolamine, 2-amino-2-methyl-1-propanol. The environment-friendly typetapping liquid prepared by adopting the preparation method has the advantages of more stable pH value and better comprehensive use performance.

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 ...
