Abstract

The invention belongs to the technical field of mine conveying pipe bodies, and discloses an anti-static flame-retardant steel skeleton fiber reinforced resin pipe and a preparation technology of the anti-static flame-retardant steel skeleton fiber reinforced resin pipe. The anti-static flame-retardant steel skeleton fiber reinforced resin pipe is technically characterized in that the anti-static flame-retardant steel skeleton fiber reinforced resin pipe comprises a pipe body which comprises a seepage-proof flame-retardant conductive inner lining layer and a pressure-bearing flame-retardant conductive structural layer from inside to outside, wherein the seepage-proof flame-retardant conductive inner lining layer comprises glass fiber solidified on an inner base body, and the pressure-bearing flame-retardant conductive structural layer comprises an outer base body which is synchronously provided with a zinc-coated steel wire and glass fiber direct roving in a winding mode, wherein epoxy resin is coated on the outer surface of the zinc-coated steel wire. According to the anti-static flame-retardant steel skeleton fiber reinforced resin pipe, matching among all layers of fiber is reasonable, mechanical property is strengthened, meanwhile, weight of the tube body is lightened, multi-wall carbon nanotubes and nanometer aluminium hydroxide are filled, fine structures of all layers are changed, meanwhile, bending resistant strength and shock resistance capability are enhanced, wear-resisting property and conductivity are largely improved, service life is prolonged, and cost is reduced.

Description

technical field

[0001] The invention belongs to the technical field of conveying pipes, and in particular relates to an antistatic and flame-resistant steel skeleton fiber-reinforced resin pipe and a preparation process thereof. Background technique

[0002] Similar types of steel skeleton fiber reinforced resin pipes, high strength resin steel mesh composite pipes and antistatic flame retardant fiber reinforced resin composite pipes used in coal mine conveying pipes are usually composed of surface conductive layer, middle strength layer, inner Lining wear-resistant layer composition.

[0003] 1. The surface conductive layer is usually formed by curing fibers, resins, curing agents and accelerators, adding flame retardants, antistatic agents, and conductive carbon black. Since the surface resistance value of the pipe body used in the mine environment is generally required to be within 10 4 —10 8 Ω, and must comply with the relevant requirements of the AQ1071-2009 pipe bod...
