Abstract
The present invention relates to the field of polyethylene pipe, and to an underground mining polyethylene pipe, comprising 100 parts by mass of PE 80, 11.3-32.1 parts by mass of zinc borate-magnesium hydroxide fire retardant and 1.9-2.6 parts by mass of conductive acetylene black. The underground mining polyethylene pipe of the invention has the advantage of innocuity, non-harm and security environmental protection because the invention selects zinc borate-magnesium hydroxide as a fire retardant, wherein the zinc borate is cheap in price, innocuous, nonirritating, and has a low impact to the mechanical strength and aging quality of the composite material, as well as has the characteristics of the common mining polyethylene pipe which is light in material and cheap in price, has an excellent flexibility, is easily to be installed, corrosion proof and hardwearing, and has a long service life. The polyethylene pipe can be generally used for drawing out methane, water supplying and draining, positive draft, induced draft and gunite.
Description
One, technical field:
The present invention relates to the polyvinyl piping materials field, is a kind of mining down-hole polyethylene pipe.
Two, background technology:
Mining polyethylene (PE) tubing obtains the increasingly extensive application in colliery with its excellent comprehensive performance.Along with of the continuous attention of national colliery to safety, along with the develop rapidly of science and technology, replace steel pipe, Glass Steel Tube with the PE pipe, become the ideal that guarantees mine safety and selected.Because the Special Circumstances under the coal mine contain macro-corrosion and inflammable, explosion hazard gases, and the oxygen index OI=17.4 of PE are the inflammableness plastics, so require PE tubing will have flame retardant resistance, static resistance.At present, use more widely fire retardant and because halogenated flame retardant is emitted HX (being the hydrogen halide serial gas) in 200 ℃ to 300 ℃ decomposition, can catch the high energy free radical H that causes degraded mostly all based on halogenated flame retardant
+(being hydrogen ion) and HO
-(being hydroxide ion) delays or termination reaction; HX is a kind of difficult combustion gas body, and density is bigger than air, can cover material surface, reduces the concentration of its inflammable gas, suppresses the burning of material.But do the time spent because of halogenated flame retardant and can produce a large amount of smog, generation poisonous and have corrosive hydrogen halide can be corroded instrument and equipment, produces secondary disaster, and the consumption of halogenated flame retardant has the trend that reduces gradually at present; The poisonous (dioxin that is produced during its burning) smog, environmental pollution is serious.
Three, summary of the invention:
The invention provides a kind of mining down-hole polyethylene pipe, solved the defective that existing mining down-hole polyethylene pipe exists, improved the safety in utilization of polyvinyl piping materials in the down-hole.
Technical scheme of the present invention is achieved like this: a kind of mining down-hole polyethylene pipe, it consists of the PE80 of 100 mass parts, the zinc borate flame retardant of magnesium hydroxide of 11.3 mass parts to 32.1 mass parts, the conductive acetylene carbon black of 1.9 mass parts to 2.6 mass parts by raw materials quality part.
Above-mentioned mining down-hole polyethylene pipe becomes the PE80 of 100 mass parts, the zinc borate flame retardant of magnesium hydroxide of 22.2 mass parts, the conductive acetylene carbon black of 2.1 mass parts by raw materials quality part best group.
The characteristics such as common mineral polyethylene piping materials light weight is inexpensive, snappiness good except that having for mining down-hole polyethylene pipe of the present invention, be convenient to install, corrosion-resistant, wear-resistant, long service life, also selected the zinc borate magnesium hydroxide as fire retardant, zinc borate is inexpensive, nontoxic, non-stimulated, mechanical strength and heat aging performance influence to matrix material are little, therefore the polyvinyl piping materials of producing also has nontoxic nothing harm, the advantage of safety and environmental protection.It can be common to draw out methane, purposes such as water supply and drainage, positive draft, exhaust ventilation, whitewashing.
Five, embodiment:
The present invention is not subjected to the restriction of following embodiment, can determine concrete embodiment according to technical scheme of the present invention and actual needs.
Embodiment 1: this polyvinyl piping materials consists of the PE80 of 100 mass parts, the zinc borate-flame retardant of magnesium hydroxide of 32.1 mass parts, the conductive acetylene carbon black of 2.1 mass parts by mass parts.
Embodiment 2: this polyvinyl piping materials consists of the PE80 of 100 mass parts, the zinc borate-flame retardant of magnesium hydroxide of 22.2 mass parts, the conductive acetylene carbon black of 2.6 mass parts by mass parts.
Embodiment 3: this polyvinyl piping materials consists of the PE80 of 100 mass parts, the zinc borate-flame retardant of magnesium hydroxide of 11.3 mass parts, the conductive acetylene carbon black of 1.9 mass parts by mass parts.
The foregoing description 1 to 3 still adopts existing known production polyvinyl piping materials method to obtain needed polyvinyl piping materials.And detect according to coal industry standard MT588.1-2005 " underground mine use plastic pipe " first part's polyvinyl piping materials, its every performance index all reach the standard of defined.Concrete detection is as follows:
Hydraulic test: measure according to GB/T6111-2003 " fluid is carried with thermoplastic plastic pipe internal pressure-resistant experimental technique ".Pressurize 100h under test pressure, tubing ne-leakage and destruction.
Tensile strength and elongation rate of tensile failure: measure according to GB/T8804-2003 " thermoplastic plastic pipe tensile property mensuration ".Tensile strength 〉=9.0Mpa, elongation rate of tensile failure 〉=300%.
Surface resistivity: measure according to MT181-88 " underground mine use plastics tubing safety performance inspection specification ".The inside and outside wall surface resistance of tubing arithmetical av≤1.0 * 10
6Ω.
Alcohol blast burner combustion experiment: measure according to MT181-88 " underground mine use plastics tubing safety performance inspection specification ".1) arithmetical av≤3s of 6 sample flaming combustion times, the flaming combustion time≤10s of wherein any sample; 2) 6 sample flameless combustion time≤20s, the flameless combustion time≤60s of wherein any sample.
Common mineral polyethylene piping materials light weight is inexpensive, pliability good except having for mining down-hole polyethylene pipe of the present invention, be convenient to peace Outside the characteristics such as dress, corrosion-resistant, wear-resistant, long service life, also has nontoxic nothing harm, the advantage of safety and environmental protection.
