Abstract
An electric spark processing liquor belongs to the technical field of electric discharge processing liquor which is formed by mixing solvent oil and tetradecane alkane according to a weight percentageof 1:1 to 2.5. One advantage of the electric spark processing liquor provided by the invention is that the service life can reach 16 to 30 months; a second advantage is that a flash point (cut) can reach 105 to 110 DEG C; a third advantage is that content of aromatic hydrocarbon is low which is equal to or lower than 0.5 percent and the viscosity is suitable with movable viscosity of 2.1mm<2>s.
Description
Technical field
The invention belongs to the processing liquid discharge technical field, be specifically related to a kind of electric spark processing liquid.
Background technology
Electric spark processing liquid is also referred to as processing liquid discharge, and the english abbreviation of discharge processing is EDM.Along with the progress of industrial development and science and technology, Electric Discharge Machining has been widely used in to the processing such as space flight, military project, electronics, machinery, mould or the like product.The mechanism of Electric Discharge Machining is to being immersed in workpiece in the working fluid by the galvanic corrosion operation that produces during pulsed discharge between electrode and controlledly make the special process method of electrically conductive workpiece moulding, when electrically conductive workpiece is carried out processing and forming, must be full of liquid medium between two electrodes, this liquid medium is aforesaid electric spark processing liquid.The performance that electric spark processing liquid should possess is: flash-point (opening) is high, security is good, kinematic viscosity is suitable (usually at 1.5-2.5mm
2/ S scope), cooling property and good insulating, arene content be low, to health harmless and non-corrosiveness, long service life etc., wherein: the requirement for service life, flash-point, arene content, viscosity is very exquisite.
In the prior art, the product that is used as electric spark processing liquid mainly contains two kinds, and one is kerosene, and two is Dormant oils type electric spark processing liquid.The former deficiency is: only be about 3 months service life; Flash-point is 50 ℃, and arene content is big, more than 10%; Viscosity is 1.5.The latter's shortcoming point: for the former, the flash-point height can reach 100 ℃, but ties carbon easily; The arene content height is below 10%; Service life is still desirable not to the utmost, is about about 6 months; Kinematic viscosity is bigger than normal, about 3.
Because the service life of above-mentioned two kinds of electric spark processing liquids is short, must frequently change, therefore not only cause the application cost of applying unit or claim workpiece processing cost height, and frequently cause serious waste of resources owing to changing.If to external import, its price is difficult to make China that enterprise can bear again so.
In the literature, for example in patent documentation, the applicant only retrieves the discharge-treating method that one piece of Granted publication number is called the processing liquid discharge body for CN1038732C, name and uses this liquid, this patented technology scheme technical problem to be solved is the fine finishining quality that improves workpiece, make surface of the work level and smooth, thereby do not reach all the other instructions like mirror.
Summary of the invention
Task of the present invention is that the electric spark processing liquid that a kind of long service life, flash-point height, arene content are low, viscosity is suitable will be provided.
Task of the present invention is finished like this, a kind of electric spark processing liquid, and it is to be mixed than 1: 1～2.5 by weight by solvent naphtha and 14 carbon n-alkanes, and described solvent naphtha is a special solvent oil, and described special solvent oil is a D100 type solvent naphtha.
The weight part ratio of solvent naphtha of the present invention and 14 carbon n-alkanes is 1: 1～2.
The weight part ratio of solvent naphtha of the present invention and 14 carbon n-alkanes is 1: 1.
One of advantage of electric spark processing liquid provided by the present invention was 16-30 month service life; Two, flash-point (opening) can reach 105-110 ℃; Three, arene content is humble, only is≤0.5%; Viscosity is suitable, and kinematic viscosity (40 °) is 2.1mm
2/ s.
