Abstract
The invention relates to an antistatic flame-resistant pipe used on places with the antistatic flame-resistant requirements, such as a mine, and the like. The antistatic flame-resistant pipe comprises the flowing material ingredients by weight percentage: 70 to 72 of high-density polythene resin, 6 to 10 of conductive carbon black, 19 to 23 percent of carbon-series compound flame retardant and 1 to 2 of modified additive, wherein the carbon-series compound flame retardant comprises 31 to 32 percent of phosphorus, 14 to 15 percent of nitrogen and smaller than 0.25 percent of water by the weight percentage and has a decomposition temperature of higher than 280 DEG C. Tests prove that the antistatic flame-resistant pipe has excellent antistatic flame-resistant performance, good anti-aging performance, brittleness resistance, high compressive resistance, high impact compression and low density.
Description
Technical field
The present invention relates to a kind of have in colliery etc. have anti-antistatic flame-resistant pipe for using in the occasion of anti-electrostatic requirement.
Background technology
Traditional mining pipes mainly contains steel pipe, cast iron pipe and Glass Steel Tube.Steel pipe, cast iron pipe bump easily in the down-hole and produce spark, and the danger that causes gas explosion is arranged, and corrosion easily; The fragility problem of Glass Steel Tube is difficult to be resolved, and it is easily damaged to be hit, and these three kinds of materials are than great, cause tubing transportation, install very inconvenient.China begins the development and the application of mineral polyethylene piping materials from the end of the eighties in last century, but existing polyvinyl piping materials material rate is lower, generally can only reach the MPE80 grade, and every performance index and service requirements gap are bigger; And employed fire retardant in the existing polyvinyl piping materials all adopts traditional bromine, antimony composite flame-retardant agent, and this auxiliary agent can produce a little obnoxious flavour in plasticizing process, can influence the healthy of direct labor, and its flame retardant properties is difficult to improve.
Summary of the invention
Technical problem to be solved by this invention provide a kind of in light weight, material rate is high, production process is polluted little antistatic flame-resistant pipe.
The weight percent of the material composition of antistatic flame-resistant pipe of the present invention is: high-density polyethylene resin 70～72%, conductive carbon black 6～10%, phosphorus series composite flame retardant 19～23%, modified additive 1～2%; The phosphorus content weight percent is 31～32% in the phosphorus series composite flame retardant wherein, and nitrogen content per-cent is 14～15%, decomposition temperature＞280 ℃, moisture content weight percent＜0.25%.
The trade mark of described high-density polyethylene resin is YGH041.
The pH value of described conductive carbon black is 6.0, be that 990g/kg (DBP), absorption value are that 6.0m ι/g, nitrogen adsorption specific surface area are 890m than resistance 0.20 Ω cm, iodine absorption value
2/ g, weight loss on heating are 1.0%, the plastics volume specific resistance is that 2.3 Ω cm, frosting resistivity are 30.6 Ω cm.
Described phosphorus series composite flame retardant is that the model of being produced by the big chemical industry company limited in sea, Qingdao City is the phosphorus series composite flame retardant of FR-508B.
Tubing of the present invention has the excellent fire retardant antistatic property through experimental verification; Simultaneously its ageing resistance is good, is difficult for embrittlement, and is withstand voltage, impact strength is high, can reach MPE100 level material rate; This tubing density is little in addition, and the quality of same volume only is 1/7 of a steel pipe, 1/3 of Glass Steel Tube, and be 4-6 times of steel pipe work-ing life.Because light weight, the transportation of tubing, install all very convenient, also can be light by about 5.5% even compare the quality of its same volume with the mining high-performance polyethylene pipe material product of existing MPE80 level.
