The invention provides a fatty acid polyoxyethylene succinic acid ester sulfonate, which is characterized by having a structure shown in the specification. Specifically, n is an integer of 2-15, R is alkyl with a carbon atom number of 7-19, and M is Na or K. Compared with the prior art, the micro-cutting fluid made from the fatty acid polyoxyethylene succinic acid ester sulfonate provided by the invention has good lubricity and biodegradability, a small amount of the micro-cutting fluid can meet the high-end demands of metal processing, the harm to the environment and workers is reduced, and the environmental pollution can be minimized.

The invention discloses strong peptizer and a method for preparing the same. The compositions of the strong peptizer are: 2 to 4 milliliters of phenol, 3 to 5 milliliters of petroxolin, 8 to 10.5 grams of sodium hydroxide, 4 to 5.6 milliliters of ethanol, 5 to 5.4 grams of stearic acid, 3 to 5 milliliters of tween-80, 70 to 75 milliliters of water and 13 to 15.5 grams of dodecyl sodium sulfate. The preparation method is as follows: a. the water is heated to between 75 and 82 DEG C, and the sodium hydroxide, the stearic acid, the tween-80, the phenol, the petroxolin and the dodecyl sodium sulfate are added into the water; the mixture is stirred for 30 minutes at the speed of 850 turns per minute at a temperature of between 75 and 82 DEG C, and then cooled; b. jellies are uniformly stirred and placed into a container, and added with 4 milliliters of water and stirred at the speed of 700 turns per minute; c. hydrochloric acids are used for adjusting the pH value to between 8 and 9, and acoarse product is obtained; d. methylene dichloride is used as propellants, and high-pressure filling of liquefied gas is performed on the product. The strong peptizer provided by the invention can make firmly glued paper rapidly fall off; and the preparation method is simple and the cost is low.

The invention discloses a technology for preparing fatty acid polyoxyethylene ether ricinoleate. The technology includes the steps that the main ingredient glyceryl ricinoleate in raw materials of ethoxylated fatty alcohol and castor oil is heated to be boiled under the combined action of an organic tin catalyst, a polymerization inhibitor and entrainer methylbenzene, and then the fatty acid polyoxyethylene ether ricinoleate can be obtained through transesterification. By the adoption of the technology, the azeotropic fractionation ester exchange process is adopted, micromolecule alcohol, acid and the like of by-products in the reaction process are removed from a fractionator by means of azeotropic distillation, and thus the polyoxyethylene ether ricinoleate with the single ingredient is obtained. Serving as the main intergradient of a high fat film, the product prepared through the method has good wetting, film formation and lubricating effects, the high corrosion resistance is further achieved, and the defect that the high fat film is prone to corrosion is effectively overcome. The product has extremely-high stability at the normal temperature and can be effectively mixed with various pesticides and plant nutritional ingredients, uniform high fat films can be formed on the surfaces of plant bodies, and the requirement for the high fat films with different purposes can be met.

A kind of organic molybdenum lubricant composition provided by the present invention is characterized in that, it is prepared by comprising laccarnation acid, ammonium phosphomolybdate, polyethylene glycol, monoethanolamine, phosphorus pentoxide, the composition of The ratio of parts by weight is: Lacic acid 100; polyethylene glycol 50-100; ammonium phosphomolybdate 15-20; monoethanolamine 8-10; phosphorus pentoxide 5-8. The organic molybdenum lubricant composition prepared by the invention is an extreme pressure anti-wear additive containing Mo-P-S-N, has excellent friction-reducing performance, and is also a good surfactant. A micro-quantity lubricant containing an organic molybdenum lubricant composition, which is prepared from the following components in weight percent: organic molybdenum lubricant composition 30-40%; octyldodecyl myristate 30-40%; Polycastor oil maleate 5‑10%; Sodium castor oil sulfonate 5‑10%; Deionized water balance. The micro-quantity lubricant prepared by the invention can meet the lubricating cooling, extreme pressure anti-wear and anti-rust requirements of metal processing; when used with a micro-quantity lubrication device, the amount of lubricant used can be saved by more than 90%.

The invention provides a fatty acid polyoxyethylene succinate sulfonate, which is characterized in that it has the following structure: wherein, n is an integer of 2 to 15, R is a hydrocarbon group with 7 to 19 carbon atoms, and M is Na or K, the micro-cutting fluid produced by using the fatty acid polyoxyethylene succinate sulfonate provided by the invention has good lubricity and biodegradability compared with the prior art, and a very small amount of micro-cutting fluid It can meet the high-end requirements of metal processing, reduce the harm to the environment and workers, and minimize the pollution to the environment.
