Abstract
The utility model discloses an antistatic and flame-retardant polyethylene composite pipe used in a coal mine. The antistatic and flame-retardant polyethylene composite pipe is structurally composed of six layers sequentially including an antistatic layer, a high-density polyethylene layer, a bonding resin layer, a flame-retardant layer, a bonding resin layer and an antistatic and flame-retardant composite layer from outside to inside, and a further improvement includes that the antistatic layer is a UV antistatic coating. The antistatic and flame-retardant polyethylene composite pipe is high in antistatic performance, flame-retardant performance and mechanical performance.
Description
Technical field
The utility model relates to a kind of tubing, relates in particular to a kind of underground mine use polyethylene composite pipe.
Background technique
Polyvinyl piping materials is because having light weight, corrosion resistant feature, be widely used in underground mine use, but polyvinyl piping materials is antistatic, flame retardant property is poor, in order to guarantee usage requirement under coal mine, in polyethylene pipe, need to add a large amount of flame-retardant master batch and anti-static agent, the mechanical property of polyethylene pipe is obviously declined, and polyethylene pipe is short working life.
Summary of the invention
The utility model, for the deficiencies in the prior art, proposes a kind of antistatic, fire-retardant underground mine use polyethylene compound pipe that simultaneously possesses good mechanical property, anti-static electricity property, flame retardant property.
The utility model is achieved through the following technical solutions technical goal.
Antistatic, fire-retardant underground mine use polyethylene compound pipe, its improvements are: described antistatic, fire-retardant underground mine use polyethylene compound pipe is comprised of six layers of structure, are antistatic layer, high-density polyethylene layer, bonding resin layer, flame-retardant layer, bonding resin layer, antistatic, fire-retardant composite bed from outside to inside successively.
In said structure, described antistatic layer thickness is 0.2～0.4 mm.
In said structure, described antistatic, fire-retardant composite bed thickness is 0.6～0.8 mm.
In said structure, described antistatic layer is UV antistatic coating.
In said structure, described bonding resin layer, bonding resin layer are the polyethylene polymer of maleic anhydride and tackifying resin modification.
In said structure, described flame-retardant layer is made by following material (mass percent): polyethylene resin 75～80%, environmental protection fire retarding agent 20～25%.
In said structure, described antistatic, fire-retardant composite bed is made by following material (mass percent): polyethylene resin 75～80%, environmental protection fire retarding agent 15～20%, the antistatic carbon black 5～8% of superconduction.
The utility model compared with prior art, has following good effect:
1. be provided with inside and outside two-layer antistatic layer, flame-retardant layer, make the utility model possess antistatic, flame retardant property preferably, electrostatic layer, flame-retardant layer do not affect mechanical property of the present utility model.
2, antistatic layer is UV antistatic coating, and UV antistatic coating possesses higher anti-static electricity property, further improves to obtain anti-static electricity property of the present utility model.
3, bonding resin layer is the polyethylene polymer of maleic anhydride and tackifying resin modification, the bond effect that can guarantee.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings and in conjunction with the embodiments below.
Antistatic, fire-retardant underground mine use polyethylene compound pipe shown in the drawings, is comprised of six layers of structure, is antistatic layer 1, high-density polyethylene layer 2, bonding resin layer 3, flame-retardant layer 4, bonding resin layer 5, antistatic, fire-retardant composite bed 6 from outside to inside successively.
Antistatic layer 1 thickness is 0.2～0.4 mm, and in the present embodiment, antistatic layer 1 thickness is 0.4 mm; Antistatic, fire-retardant composite bed thickness is 0.6～0.8 mm, and in the present embodiment, antistatic, fire-retardant composite bed thickness is 0.8 mm.
In the present embodiment, antistatic layer 1 is UV antistatic coating.
Bonding resin layer 3, bonding resin layer 5 are the polyethylene polymer of maleic anhydride and tackifying resin modification.
Flame-retardant layer 4 is made by following material mass percent: polyethylene resin 75～80%, environmental protection fire retarding agent 20～25%.
Antistatic, fire-retardant composite bed 6 is made by following material mass percent: polyethylene resin 75～80%, environmental protection fire retarding agent 15～20%, the antistatic carbon black 5～8% of superconduction.
