Abstract

The invention discloses a spark-oil-resistant rubber protective cover and a preparation method thereof. The spark-oil-resistant rubber protective cover is prepared from the following raw materials in parts by weight: 50-70 parts of nitrile-butadiene rubber, 30-50 parts of chloroprene rubber, 7-12 parts of carbon black, 4-6 parts of DOP (dioctyl phthalate), 0.5-1.5 parts of stearic acid, 0.5-1.5 parts of paraffin, 0.5-1.5 parts of anti-aging agent RD, 0.5-1.5 parts of 4010 Na, 3-6 parts of light magnesium oxide, 0.2-0.4 part of sulfur, 0.6-1 part of DM, 0.6-1 part of TMTD (tetramethyl thiuram disulfide), 2-3 parts of nano ZnO, 0.1-0.5 part of NA-22 and 0.5-1.5 parts of DCP (dicumyl peroxide). The spark-oil-resistant rubber protective cover has favorable spark oil resistance and fire resistance, and can not be combusted within 20 seconds under the naked fire generated by the EDM machine tool.

Description

technical field [0001] The invention relates to the technical field of electric spark equipment, in particular to an electric spark oil-resistant rubber protective cover and a preparation method thereof. Background technique [0002] EDM machine tool, also known as CNC EDM machine tool, EDM, spark machine, etc., is a kind of electrical processing equipment. EDM is in the lower voltage range, using the corrosion phenomenon generated during spark discharge in EDM oil to process the size of the material. EDM oil is the product of hydrogenation of kerosene components. It is an indispensable discharge medium liquid for EDM. It can insulate and deionize, cool down the high temperature during EDM machining, and remove carbon slag. [0003] During electrical machining, EDM oil will splash onto the EDM machine tool with carbon slag and metal particles. When it splashes onto the spindle guide rail, etc., it will cause wear to the guide rail and affect the accuracy of the machine tool...
