The invention discloses a flame-retardant antistatic rubber material for a conveying belt and a preparation method of the flame-retardant antistatic rubber material, and relates to the technical field of rubber materials. The rubber material is prepared from the following components: 40-80 parts of chloroprene rubber, 10-40 parts of butadiene rubber, 10-30 parts of high styrene rubber, 20-40 parts of a reinforcing agent, 15-30 parts of an antistatic agent, 10-30 parts of aluminum hydroxide, 10-20 parts of a modified flame retardant, 5-10 parts of polyethylene fibers, 5-10 parts of zinc stearate, 3-6 parts of a coupling agent, 4-8 parts of a vulcanizing agent, 1-3 parts of an accelerant and 1-3 parts of an anti-aging agent. Basic performance is provided through a compounding system of three kinds of rubber, the mechanical performance is improved by adopting an attapulgite-carbon black compounding reinforcing system, and the antistatic and flame-retardant functions are achieved in combination with the antistatic agent and the specially-made modified flame retardant.

The invention relates to a modified iron-nickel magnetic powder core and a preparation method and application thereof, and the preparation method comprises the following steps: putting an iron-nickel magnetic powder core subjected to insulation coating and annealing treatment into an acid solution, standing, enabling the surface of the iron-nickel magnetic powder core to react with the acid solution to generate a salt mixture coating layer, and obtaining the modified iron-nickel magnetic powder core. A pickling method is adopted, the iron-nickel magnetic powder core subjected to insulation coating and annealing treatment is subjected to surface treatment, an acid solution reacts with metal elements on the surface of the iron-nickel magnetic powder core to generate a salt mixture coating layer containing iron and nickel, and the coating layer plays an insulation role; therefore, the resistance of the iron-nickel magnetic powder core can be improved, the loss can be reduced, the performance of the modified iron-nickel magnetic powder core can be obviously improved, and the situation that the surface resistance is low, the loss is high and the service life is long due to decomposition of an insulating layer caused by incomplete insulation coating or too high heat treatment temperature, insufficient atmosphere protection and the like of the iron-nickel magnetic powder core is avoided. And normal use cannot be realized.
