Description
Technical Field
The invention relates to the technical field of coal mine roadway building materials, in particular to antistatic paint for an anchor rod, and a preparation method and application thereof.
Background
The composite material anchor rod is a fiber reinforced resin matrix composite material prepared by taking epoxy resin (unsaturated polyester resin, vinyl resin and the like) as a matrix material and high-performance fibers (glass fibers, basalt fibers, aramid fibers, ultra-high molecular weight polyethylene fibers, carbon fibers and the like) as a reinforcing material and adopting a pultrusion process. According to the standard requirements of coal mines, the length of the composite anchor rod after cutting is generally between 1.4 and 2.6m, and the nominal diameter is between 18 and 32 mm.
Coal mine tunnels are currently generally supported by metal anchor rods and anchor nets, and comprise coal mining sides and tops on two sides, while composite anchor rods are generally used on the coal mining sides and the side walls of a coal mine. In the published data, the top of a coal mine tunnel is generally supported by a metal anchor rod, two side walls of the coal mine tunnel are supported by the metal anchor rod or a common glass fiber anchor rod and an anchor net, and a layer of concrete is laid on the outer layer of the support for reinforcement.
The common glass fiber anchor rod is a rod-shaped product which is prepared by taking epoxy resin (unsaturated polyester resin, vinyl resin and the like) as a base material and glass fiber as a reinforcing material through a pultrusion process. However, the common glass fiber anchor rod has the defects of over-small torque, poor flame retardant property and no antistatic property, and can generate sparks under the condition of high requirements on coal mine environment to influence the safety of a mine hole.
The metal anchor rod is a rod-shaped metal rod body formed by a round steel after being fixed, cut and pressed by a machine and then being subjected to a thread rolling process. The torque and the shear strength are high, but the metal anchor rod per se is conductive, so that certain risks can exist in the use in a coal mine.
