Problems solved by technology

However, the existing plastic pipes have a small caliber and cannot meet the overall requirements of the existing coal mines; the second is that the antistatic agent is selected from ionic antistatic agents, nonionic antistatic agents and zwitterionic antistatic agents. It has antistatic effect, but not only the price is high but the effect is not obvious

Embodiment 1

[0020] The material composition and the percentage by weight of each composition are:

[0021] High-density polyethylene 87% (TR490 produced by Phillips, USA)

[0022] Microencapsulated red phosphorus 9% (AMGARD CRP commercial product)

[0023] Conductive carbon black 4% (Mitsubishi carbon black Japan 3350)

[0024] Mix the above three raw materials in a high-speed mixer for 120 seconds, and then add them into a twin-screw extruder for melt blending and extrusion. The screw speed is 180 rpm, the processing temperature is 200°C, the middle is decompressed and exhausted, and the extrusion speed is 0.5 m / min. After cooling, coiling and packaging, it becomes a finished product.

Abstract

The invention relates to a mine structural tube material, which is characterized in that: said tube is formed by high-density polythene added with anti-static agent and flameproof agent, while the mass percentages comprise: high-density polythene at 80-87%; the flameproof agent at 8-10%, wherein the flameproof agent is micro capsule red phosphorus; the anti-static agent is conductive carbon black. The invention can be used to supply water, discharge water, compress wind, plate pulp, and exhaust gas. The invention has the advantages that: the tube is added with flameproof agent to obtain high flameproof property; the tube is added with anti-static agent to reduce the surface resistance. The invention has light weight and anti-pressure property.

Description

Technical field: [0001] The invention relates to a novel polyethylene pipe material, in particular to a structural wall pipe material for coal mines. Background technique: [0002] In recent years, the country has vigorously promoted the application of plastic pipes. Plastic pipes are constantly replacing metal and other traditional material pipes with their excellent performance and energy-saving features, and their development is very rapid. So there is the third largest category of pipes for coal mines - plastic pipes. It has the following excellent characteristics: antistatic, flame retardant; non-toxic, corrosion resistant, high pressure resistant; light in weight, easy to install, it is an ideal pipe material for "replacing steel with plastic" and realizing resource optimization. However, the existing plastic pipes have a small caliber and cannot meet the overall requirements of the existing coal mines; the second is that the antistatic agent is selected from ionic an...
