Abstract
The invention relates to the technical field of coal-bed pipes and discloses a polyethylene (PE) pipe for coal-bed methane drainage and a manufacturing method thereof. The PE pipe for coal-bed methane drainage comprises the following raw materials in parts by weight: 50 to 70 parts of PE resin, 20 to 35 parts of flame-retardant master batch, 1 to 4 parts of lubricating agent and 0.5 to 3 parts of brightening agent. According to the PE pipe for the coal-bed methane gas drainage in a coal mine, the domestic gap is filled, the requirement of the coal-bed methane drainage project is met, the PE pipe for the coal-bed methane drainage is low in cost, high in flame-retardant property, high in strength and outstanding in toughness, the performance index accords with the specified Q/WS10-2009 standard, the whole production process of the product is simple and efficient, and the economic benefits are improved.
Description
Technical field
The present invention relates to a kind of coal seam tubing technical field, related in particular to a kind of coal-seam gas extraction with PE pipe and preparation method thereof.
Background technology
As everyone knows, below underground 1000m, also exist coal-seam gas simultaneously in the dark coal seam, it not only contains toxic gas, and contains a large amount of inflammable gases, and this brings very big inconvenience to exploitation, is prone to cause combustion explosion.In recent years, colliery scientific and technical personnel research was carried out extraction to the coal-seam gas at underground 1000m-2000m deep layer place before unminding in the colliery, carried out elder generation and got rid of afterwards and exploit, and made colliery safe working smoothly.
Colliery coal-seam gas gas drainage PE pipe exactly before exploitation, this pipe is put into deep under ground, utilizes the hole on this pipe circumference that coal-seam gas is extracted out.At present, existing high especially abroad with the performance product price, the production cycle is long, need again to buy with foreign exchange; Because it is with high costs, performances such as flame retardant properties, intensity, toughness are difficult to meet increasingly high production requirement, therefore, are badly in need of the colliery coal-seam gas gas drainage PE pipe that a kind of accords with production requires.
Summary of the invention
The coal-seam gas extraction that the purpose of this invention is to provide a kind of low cost, flame retardant properties is good, intensity is high, toughness is outstanding is with PE pipe and preparation method thereof.
In order to solve the problems of the technologies described above, the present invention is able to solve through following technical proposals:
