Abstract

The invention discloses an instrument signal line insulation coating and a preparation method thereof, and relates to the technical field of signal line materials. The instrument signal line insulation coating is prepared from, by weight, 35-40 parts of epoxy resin, 10-15 parts of C9 petroleum resin, 10-15 parts of chlorosulfonated polyethylene, 6-10 parts of cinerite, 5-8 parts of petroleum coke, 5-8 parts of rubber powder, 4-6 parts of carnauba wax, 4-6 parts of plastification additive, 3-5 parts of asbestos powder, 3-5 parts of molecular sieve raw powder, 2-3 parts of cetyl alcohol, 2-3 parts of chlorinated paraffin, 1-2 pars of wool fat, 1-2 parts of aluminum-magnesium silicate and 0.1-0.2 part of nano lanthanum oxide. The insulation coating has excellent moisture resistance, fire resistance and insulation performance, the service life of an insulation layer is effectively prolonged, and therefore a signal line is protected better. By means of the added plastification additive, the flexibility of a coating can be enhanced, the adhesive force of the coating on the insulation layer can be fully improved, and the phenomenon that a coating is pulverized and falls off after the signal line is used for a long time is avoided.

Description

Technical field: [0001] The invention relates to the technical field of signal line materials, in particular to an insulating coating for instrument signal lines and a preparation method thereof. Background technique: [0002] The instrument signal line is used to output the signal of the instrument to control the operation of the equipment and the feedback signal of the working state of the input equipment to reduce the workload and achieve precise and high-efficiency processing. Due to the different working environments of instrument signal lines, some instruments require their signal lines to have excellent insulation to ensure production safety. Therefore, the method of wrapping the rubber layer outside the signal core is usually used to improve the insulation. However, the service life of the rubber layer is limited, and its insulation cannot be guaranteed in case of wear. In response to this situation, our company has developed an insulating coating for instrument si...
