Problems solved by technology

[0002] Cutting oils, coolants, emulsions and other lubricants used in traditional metal processing lubrication and cooling are used in large quantities, and traditional lubricating oils use mineral oil as the base oil, which is not easy to decompose in the natural environment, and most of the additives used are harmful to the human body. Harmful to the environment, it not only wastes resources, but also causes huge pollution of processing sites and the environment

Embodiment 1

[0017] The 2-ethyl azelate of 350kg, the neopentyl polyol ester of 320kg, the zinc dialkyl dithiophosphate ZDDP of 50kg, the polyester of 20kg, the N-lauroyl alanine of 10kg are fully stirred and Heat to 50°C, add 250kg of polyalphaolefin PAO, keep constant temperature and fully stir for 60 minutes, then pack after natural cooling.

Embodiment 2

[0019] 320kg of isodecyl sebacate, 200kg of trimethylolpropanol ester, 130kg of pentaerythritol ester, 60kg of zinc dialkyldithiophosphate ZDDP, 30kg of polyester, 20kg of N-lauroyl propyl The amino acid was fully stirred and heated to 50°C, then 240kg of polyalphaolefin PAO was added, kept at a constant temperature and fully stirred for 60 minutes, and then packaged after natural cooling.

Embodiment 3

[0021] 160kg of isodecyl sebacate, 180kg of 2-ethyl azelate, 150kg of neopentyl polyol ester, 100kg of trimethylol propanol ester, 100kg of pentaerythritol ester, 50kg of dioxane Zinc dithiophosphate ZDDP, 25kg of polyester, 15kg of N-lauroylalanine were fully stirred and heated to 50°C, then 220kg of polyalpha-olefin PAO was added, kept at constant temperature and fully stirred for 60 minutes, then cooled naturally After packing.

[0022] The biodegradable quasi-dry cutting oil prepared by the present invention can be applied to turning, sawing, milling, tapping, drilling, reaming, boring, bending, stamping, and forming processes in the processing of non-ferrous metals or ferrous metals areas of lubrication and cooling. When used with a quasi-dry cutting device, the amount of lubricant used can be reduced to less than 10% of the original, and it can be biodegraded, greatly reducing the pollution to the environment.

Abstract

The invention relates to the technical field of chemistry, in particular to biodegradable quasi dry cutting oil and a preparation method thereof. The biodegradable quasi dry cutting oil is characterized in that the cutting oil is prepared from the following raw materials in percentage by weight: 30 to 40 percent of diester, 30 to 40 percent of polyol ester, 20 to 30 percent of poly alpha-olefin PAO20, 5 to 6 percent of zinc dialkyl dithiophosphate (ZDDP), 2 to 3 percent of polyester and 1 to 2 percent of N-laurel acyl alanine. Compared with the prior art, the cutting oil has good lubricating property and extreme pressure abrasion resistance, is biodegradable, and reduces the environmental pollution to minimum.

Description

[technical field] [0001] The invention relates to the field of chemical technology, in particular to a biodegradable quasi-dry cutting oil and a preparation method thereof. [Background technique] [0002] Cutting oils, coolants, emulsions and other lubricants used in traditional metal processing lubrication and cooling are used in large quantities, and traditional lubricating oils use mineral oil as the base oil, which is not easy to decompose in the natural environment, and most of the additives used are harmful to the human body. Harmful to the environment, it not only wastes resources, but also causes huge pollution of processing sites and the environment. [Content of the invention] [0003] The purpose of the present invention is to overcome the deficiencies of the current technology, adopt a new formula to prepare biodegradable quasi-dry cutting oil suitable for use in quasi-dry machining lubrication systems, and use it in conjunction with quasi-dry cutting lubricatio...
