Embodiment 1

[0018] Preparation of polyaniline preservative: The polyaniline preservative was prepared as follows.

[0019] Add 10 grams of intrinsic polyaniline and 1 gram of silver sulfate to 100 grams of 23% sulfuric acid, stir for 2 hours at a temperature of 90°C, and after cooling, filter and wash with water three times until neutral to obtain about 50 grams of black Slurry: Take 4 grams of the slurry, add 10 grams of deionized water, add 0.2 grams of caustic soda, adjust the pH value to 8-9, then add 1 gram of borax, and stir with a high-speed disperser at 1700 rpm for 1.5 hours , make it dissolve; Add 0.004 grams of zinc sulfate, 0.35 grams of sodium nitrite, 0.4 grams of sodium benzoate, and 0.02 grams of ethanol, and continue to disperse to dissolve at a high speed of 1700 rpm with a high-speed disperser.

[0020] Obtain 15.9 grams of polyaniline water-based preservatives. Its appearance is a black aqueous solution, no peculiar smell, and its density is (20°C) kg / m 3 : 1050-1080...

Embodiment 2

[0024] The preparation of polyaniline preservative is with embodiment 1;

[0025] Preparation of the present invention:

[0026] 15 grams of triethanolamine; 45 grams of polyvinyl chloride latex; 2 grams of polyether polyols; 25 grams of polyaniline water-based antirust agent, after mixing the above-mentioned species, add 15 grams of deionized water, stir and disperse for 10 minutes with a high-speed disperser, 102 g of the product were obtained as a black liquid. It can be diluted 20 times when used by users.

Embodiment 3

[0028] The preparation of polyaniline preservative is with embodiment 1;

[0029] Preparation of the present invention:

[0030] 20 grams of triethanolamine; 55 grams of polyvinyl chloride latex; 3 grams of polyether polyols; 30 grams of polyaniline water-based antirust agent, after mixing the above-mentioned species, add 40 grams of deionized water, stir and disperse for 10 minutes with a high-speed disperser, 148 g of the product were obtained as a black liquid. It can be diluted 20 times when used by users.

Abstract

An antirust polyaniline metal cutting fluid consists of water polyaniline antiseptic 25í½30 proportion, triethanolamine 15í½20 proportion, polyethylene emulsion 45í½55 proportion, polyether polyhydric alcohol 2í½3 proportion and water 15í½40 proportion. It has better antirust and anticorrosion performances.

Description

technical field [0001] The invention belongs to the field of metal cutting fluid. Background technique [0002] When the metal material is cut according to the predetermined specifications, in order to reduce the grinding between the tool and the workpiece, increase the lubricity and take away the heat generated by the grinding, it is necessary to inject a lubricating coolant between the tool and the metal material to be cut. Referred to as cutting fluid. In addition to the above functions, the cutting fluid should also have good anti-corrosion properties to ensure that the processed parts are clean and free from corrosion. Cutting fluid is a companion in the process of metal processing, and at the same time it is a meson that can easily cause metal corrosion. At present, there are two types of cutting fluids used in metal processing in my country, namely non-water-soluble metal cutting fluids and water-soluble metal cutting fluids. In these two kinds of cutting fluids, i...
