Abstract
The invention discloses an antistatic flame-retardant PE pipe and a preparation method thereof. The PE pipe is prepared from 4-6% of fire retardant, 0.5-1.5% of auxiliary flame retardant, 4-6% of antistatic agent and 86-91% of PE base material. The auxiliary components in the formula are concentrated first to prepare dual-resistance master batch, then the master batch is mixed with body resin in proportion, and then the materials are extruded and granulated through a twin-screw extruder. The PE pipe has the advantages of being good in ageing resistance and not prone to embrittlement, having good toughness and impact energy absorption, and being good in rapid crack resistance and corrosion resistance, free of scaling, smooth in inner wall and capable of improving the conveying capacity by 30%.
Description
Technical field
The present invention relates to a kind of tubing, particularly a kind of anti-electrostatic fire retardant PE pipe and preparation method thereof.
Background technology
At present, traditional mining pipes, mainly use steel pipe, cast iron pipe, plastic tube and glass reinforced plastic pipe etc..Owing to material is asked
Topic, steel pipe and cast iron pipe are susceptible to collision and produce spark in down-hole, cause the danger of gas explosion；Glass reinforced plastic pipe is hit
The most damaged；Plastic pipe has acidproof, alkaline-resisting, oil resistant, corrosion-resistant, lightweight, low cost, service year limit for length (about the 2.5 of steel
Times) etc. advantage, this is that steel tube place can not compare.But plastic pipe easily produces electrostatic, the accumulation of electrostatic may cause electrostatic
Spark discharge, consequently, it is possible to become the incendiary source of down-hole coal dust or gas explosion；Plastic pipe is the most inflammable, pressure and impact resistance
The shortcoming that property is relatively low.For making plastic pipe for coal mine material safely, reliably substitute steel pipe, it is necessary to carry out fire-retardant, antistatic
Modification with mechanical properties.
Summary of the invention
The invention aims to overcome above deficiency, a kind of ageing resistace of design is good, has good toughness,
Absorption impact energy good dispersion, properties of product are stable, anti-electrostatic fire retardant PE pipe pollution-free, beneficially large-scale production.
The purpose of the present invention is achieved through the following technical solutions: a kind of anti-electrostatic fire retardant PE pipe, by following rate of charge
One-tenth is grouped into: fire retardant 4-6%, auxiliary flame retardant 0.5-1.5%, antistatic additive 4-6%, PE base material 86-91%.
Further improvement of the present invention is: described fire retardant is decabromodiphenyl oxide (DBDPO), and described auxiliary flame retardant is
Red phosphorus-MgO, described antistatic additive is conductive carbon black；
The preparation method of a kind of anti-electrostatic fire retardant PE pipe, comprises the following steps: first first carry out the auxiliary agent component in formula concentrating,
Make dual anti-masterbatch, then dual anti-masterbatch is blended in proportion with matrix resin, then through double screw extruder extruding pelletization.
Further improvement of the present invention is: described pelletize processing temperature (DEG C) is as shown in the table:
| Ith district | IIth district | IIIth district | IVth district | Vth district | Head |
| 170 | 175 | 180 | 185 | 185 | 180 |
Melt pressure: 0.15MPa, engine speed: 40HZ；Rate of feeding: 18HZ；
Expressing technique temperature (DEG C) is as shown in the table:
| 1st district | 2nd district | 3rd district | 4th district | 5th district | |
| Barrel zone temperature | 170℃ | 180℃ | 190℃ | 195℃ | 210℃ |
| Die head temperature | 200℃ | 210℃ | 220℃ | 230℃ | 190℃ |
The present invention compared with prior art, has the advantage that
Ageing resistace is good, is difficult to embrittlement, and has good toughness, absorbs impact energy；
Its extension at break is more than 300%, and resistance to rapid cracking performance is good, can effectively avoid fracture accident；
Corrosion-resistant, non-scaling, is particularly suitable for the water of delivered downhole high-sulfur water quality, carries calcic, the isoionic water of magnesium；
Saving anticorrosion and the expense of scale removal, and be significantly larger than steel pipe service life, overall economic efficiency is 6-8 times of steel pipe；
Inner wall smooth, equivalent absolute roughness is the 2/5 of steel pipe, and transporting resistance is little, under the same conditions, can improve conveying capacity
30%。
Detailed description of the invention:
In order to deepen the understanding of the present invention, below in conjunction with embodiment, the invention will be further described, and this embodiment is only used
In explaining the present invention, it is not intended that limiting the scope of the present invention.
Embodiment 1: decabromodiphenyl oxide (DBDPO): 5%, red phosphorus-MgO:1%, conductive carbon black: 5%, PE base material: 89%.
