Description
Technical field
The present invention relates to a kind of plastic composite pipe, is specifically a kind of polyethylene composite tube for underground coal mine.
Background technique
In recent years, along with the development of China's economy, polyethylene composite tube for underground coal mine be underground coal mine for tubing such as plumbing, ventilation, whitewashing, gas pumpings, such tubing need have the requirements such as antistatic, fire-retardant.(1) existing underground mine use pipe index is not given prominence to, and material is frangible, and isostatic pressing strength is not enough; (2) existing this pipe surface intensity is not high, and wear no resistance, working life is short, in use needs continuous replacing, affects the normal production in colliery.
Summary of the invention
The object of the invention is to provide a kind of polyethylene composite tube for underground coal mine at this, there is high conductivity, dual anti-index meets the requirements.
The present invention is achieved in that a kind of polyethylene composite tube for underground coal mine of structure, and it is characterized in that: this composite pipe is divided into three layers, is flame-retardant layer in the middle part of it, and inner and outer surface is antistatic, fire-retardant composite bed, and three forms integrative-structure.
According to polyethylene composite tube for underground coal mine of the present invention, it is characterized in that: inner and outer surface is antistatic, fire-retardant composite bed thickness is 0.5mm, very thin, does not affect the tensile strength of tubing.
According to polyethylene composite tube for underground coal mine of the present invention, it is characterized in that: described flame-retardant layer is made up of following material (mass percent):
Polyethylene resin 85%, environmental protection fire retarding agent 15%.
According to polyethylene composite tube for underground coal mine of the present invention, it is characterized in that: flame-retardant layer inner and outer surface is that antistatic, fire-retardant composite bed is made up of following material (mass percent):
The antistatic carbon black 7% of superconduction, environmental protection fire retarding agent 15%, polyethylene resin 78%.
According to polyethylene composite tube for underground coal mine of the present invention, it is characterized in that: inner and outer surface is antistatic, fire-retardant composite bed resistivity 10
4Ω.
The invention has the advantages that: product of the present invention has following performance characteristics:
Fire-retardant/antistatic: the antistatic composition of polyethylene pipes for underground mine use, flame-retardant composition are evenly distributed in tubing body, thus antistatic and flame retardant property index, can not be affected because service time is long.Antistatic, flame retardant property, all higher than NBS, is applicable to the particular place that down-hole is inflammable, explosive.Inner and outer surface is antistatic, fire-retardant composite bed thickness is 0.5mm, very thin, does not affect the tensile strength of tubing; Antistatic, fire-retardant index improves.Light weight/easy for installation: polyethylene pipes for underground mine use density is little, unit weight is only 1/8 of steel pipe, 1/3 of Glass Steel Tube, thus polyethylene pipes for underground mine use transport, easy for installation, be used in the labor intensity that down-hole can reduce workman greatly, increase work efficiency.Anti-ageing, resistance to rapid cracking performance is good: polyethylene pipes for underground mine use aging quality resistance is good, not easily brittle, and has good toughness, and absorb impact energy, its breaking elongation is more than 350%, and resistance to rapid cracking performance is good, effectively can avoid fracture accident.Corrosion-resistant, non-scaling: polyethylene pipes for underground mine use is corrosion-resistant and non-scaling strong, is particularly suitable for the water of the high-alkali water quality of delivered downhole, conveying calcic, the isoionic water of magnesium.Save expense that is anticorrosion and scale removal, and working life is far away higher than steel pipe, overall economic efficiency is 6-8 times of steel pipe.
