Problems solved by technology

Metal cutting fluid is an industrial medium used to cool and lubricate cutting tools and workpieces during metal processing. However, the aluminum alloy cutting fluids currently on the market have the following problems: Scratches and breaks are prone to occur during the process; the use of high-alkaline cutting fluid will cause corrosion and black spots on the sensitive aviation aluminum alloy; the use of low-PH cutting fluid cannot protect the lathe well, and very easy to corrupt
This type of products mainly foreign cutting fluid manufacturers control the domestic market, such as Castrol, Blaser and other foreign brands, their product prices are high, the cost of use is high, which seriously restricts the development of national industries

Abstract

The invention discloses an aerolite cutting fluid with low PH value and its preparation method, and belongs to the domain of the cutting fluid. The cutting fluid is prepared from, by weight ratio, trimethylolpropane trioleate, tall oil, triethanolamine, neodecanoic acid, phosphate, benzisothiazolone, hard water resisting agent, tribasic acid, benzotriazole, castor oil polyoxyethylene ether, trihydroxy hexahydro-s-triazine, and 2, 6-bismethylmorpholine; the allowance is water. The aerolite is extremely sensitive to alkalinity; the cutting solution has low PH value due to its special preparation method and composition, and the PH value is ranged from 8.0 to 8.3; the cutting fluid is free from corrosion to the aerolite and magnalium zinc alloy which are extremely easy to corrode; moreover, the class 2 and class 7 aluminum alloys in the aerolite are big in hardness and not easy to process. The cutting solution has excellent lubricating performance and can be used for cutting during the process conveniently; the surface smoothness is high.

Description

technical field [0001] The invention relates to an aviation aluminum alloy cutting fluid with a low pH value and a preparation method thereof, and belongs to the technical field of cutting fluids. Background technique [0002] Aluminum alloy materials are currently widely used in automobile engines, transmissions, aviation equipment and other mechanical equipment industries, especially in aviation materials, about 75% are aluminum alloys. It has the characteristics of strong rigidity and strong stress corrosion resistance, especially the 7 series aluminum alloy, which is the leader among them. Because of its excellent comprehensive properties such as good toughness, high fatigue strength and good stress corrosion resistance, it is widely used in aircraft manufacturing. The ratio is getting higher and higher. However, in the past few years, the domestic 7-series aviation aluminum alloys were basically imported, and the cost was high. The 7 series aviation aluminum alloy is ...
