Problems solved by technology

Every summer, the cutting fluid used is prone to a series of problems such as PH drop, bacterial growth, odor and even employee allergies; every winter, there will be problems such as cutting fluid foam overflow
Therefore, if the pH of the liquid is too high, the operator is prone to allergies; if the pH is too low, the liquid is easy to grow bacteria
At present, when the pH of the liquid used on site decreases, it is necessary to add a pH regulator to increase the pH of the liquid used, but the pH regulator contains a fungicide, which is harmful to the human body

Embodiment 1

[0026] Add 20% of AMP-95 additive, 25% of Genamin CH 020 (J) alcohol amine, 29% of tribasic carboxylic acid antirust agent, 16% of DB-1 antirust agent and 10% of distilled water. Specifically, the following weight ratios can be used: 20g of MP-95 additive, 25g of Genamin CH020 (J) alcohol amine, 29g of tricarboxylic acid antirust agent, 16g of DB-1 antirust agent and 10g of distilled water.

[0027] The preparation process is as follows: In a beaker, add 10g of distilled water, 20g of AMP-95 and 25g of Genamin CH 020(J), stir evenly until transparent. Add 29g of tricarboxylic acid antirust agent and 16g of DB-1 and stir for 1 hour until it is uniform and transparent, and composite agent A is obtained.

[0028] In application, it is mainly used in emulsified semi-synthetic cutting fluid, the addition amount is 10-20%, the effect is the best, it has a large alkali reserve, excellent antibacterial performance and biological stability, good emulsification performance, etc.

Embodiment 2

[0031] Others are the same as Example 1, the difference is that the proportioning is different: add 18% of AMP-95 auxiliary agent, 22% of GenaminCH 020 (J) alcohol amine, 32% of tribasic carboxylic acid antirust agent, DB-1 antirust agent Rust agent 18% and distilled water 10%.

Embodiment 3

[0033] Others are the same as Example 1, except that the proportioning is different: add 22% of AMP-95 auxiliary agent, 28% of GenaminCH 020 (J) alcohol amine, 26% of tribasic carboxylic acid antirust agent, DB-1 antirust agent Rust agent 12% and distilled water 12%.

Abstract

The invention provides a bacteriostatic compounding agent applied to a metal cutting fluid, the bacteriostatic compounding agent comprises the following components by weight: 18-22% of an auxiliary agent; 22-28% of an alcohol amine; 26-32% of a ternary carboxylic acid rust preventive agent; 12-18% of a rust inhibitor and 8-12% of water. The invention also provides a preparation method and application of the bacteriostatic compounding agent applied to the metal cutting fluid. The finished product liquid of the compounding agent is colorless, uniform and fine, and is not stratified by centrifugation and standing; at the same time, the compounding agent has very good dispersibility in water, the compounding agent is mixed with a small amount of alcohol amine and an aqueous solution to rapidlyform a stable stock solution, the compounding agent is mixed with a release agent and other components to form a stable equilibrium system, and the compounding agent is very easy to formulate. Compared with the prior art, the compounding agent is has the following advantages: 1) alkali reserve is large, the change of the pH of the use liquid with time is small, the problems of pH reduction and odor can be effectively solved; 2) the bacteriostatic property of the use liquid system is improved; and 3) the product is mild and non-irritating.

Description

technical field [0001] The invention relates to an antibacterial compound, in particular to an antibacterial compound applied to metal cutting fluid, a preparation method and application. Background technique [0002] The metal cutting process refers to the process in which the redundant metal layer on the workpiece is removed by the cutting tool to form chips and obtain parts that meet the requirements of geometric shape, dimensional accuracy and surface roughness. However, in this process, there is always a contradiction between the tool cutting the workpiece and the workpiece material resisting cutting, resulting in a series of phenomena, such as cutting deformation, cutting heat, tool wear and tool life related to the tool, chip volume and fracture. Crumbs etc. Reasonable use of cutting fluid is the main way to solve the problem. In order to minimize the cutting temperature and cutting force, improve the tool life and the dimensional accuracy and surface quality of the...
