Problems solved by technology

Many fields require high-performance cables. Cables are often used in relatively harsh working environments, especially in some acid-base environments. Such working environments have high corrosion resistance for cables. If the corrosion resistance of cables is not good, many The outer surface of the cable is corroded, resulting in the breakage of the cable and the interruption of the transmission signal, which affects the transmission performance of the cable and cannot guarantee the normal transmission of the cable
Moreover, most cables have insufficient oil resistance and are difficult to be used in machine tools, automobiles, manufacturing and processing, etc.

Abstract

The invention discloses a preparation method and an application of a cable material with resistance to oil, acid and base. The method comprises the following steps: stirring and mixing an ethylene vinyl acetate copolymer and dioctyl adipate, dropwise adding trimethylolpropane triacrylate, adding the mixture to an aqueous solution of polysorbate 80 for ultrasonic processing, then adding isopropyl tri(dioctylpyrophosphate) titanate and other substances, performing a stirring reaction under an acidic condition, and washing and drying precipitates to obtain a modified mixture; vulcanizing styrene-butadiene rubber, adding dimethicone, and performing stirring in a heat preserving manner to obtain a vulcanized rubber mixture; grinding and refining attapulgite, magnesium hydroxide and other substances in an alkaline solution, regulating pH to neutral, leaving a mixture to stand overnight and performing centrifugation to obtain centrifugation precipitates; finally, mixing the products, adding polyoxypropylene-polyoxyethylene glycerol ether and other substances for kneading, adding a dispersing agent and an antioxidant, and performing mixing and granulation to obtain a finished cable material. The prepared cable material is high in oil resistance and resistant to acid-base corrosion and has good application prospect in cable manufacture.

Description

technical field [0001] The invention relates to the technical field of cable materials, in particular to a preparation method and application of an oil-resistant, acid- and alkali-resistant cable material. Background technique [0002] The cable is usually a rope-like cable twisted by several or several groups of wires. Each group of wires is insulated from each other and is often twisted around a center. Energized, externally insulated features. Many fields require high-performance cables. Cables are often used in relatively harsh working environments, especially in some acid-base environments. Such working environments have high corrosion resistance for cables. If the corrosion resistance of cables is not good, many The outer surface of the cable is corroded, causing the cable to break and the transmission signal to be interrupted, which affects the transmission performance of the cable and cannot guarantee the normal transmission of the cable. Moreover, most cables have...
