Abstract
The present invention relates to the production method of poly-second (third) alkene of a kind of modification, technical scheme is: mixing again after heating, drying, the kneading with poly-second (third) alkene mixing after coal gangue is pulverized, poly-second (third) the alkene material of modification is made in pelletizing.The present invention utilizes trade waste---and coal gangue production modification gathers second (third) alkene material, reduce cost about 60% than producing poly-second (third) alkene material, improved the technical features such as tensile strength, instant blasting pressure of material, can reduce the mining area coal gangue again simultaneously and increase and appropriation of land.
Description
The present invention relates to the production method of poly-second (third) alkene of a kind of production method of plastics, particularly modification.
At present, the plastic pipe that people often use, sheet material etc. are generally made by materials such as polyethylene, polyvinyl chloride, polypropylene, and the key technical indexes such as the cost height of these materials and tensile strength, hydro-test are on the low side, can not satisfy service requirements.
The object of the invention is to overcome the shortcoming of above-mentioned prior art and the production method of poly-second (third) alkene of the low modification of a kind of technological performance and cost is provided.
The object of the present invention is achieved like this: after coal gangue was pulverized, with poly-second (third) alkene mixing, heat drying was mixing again after mediating, and poly-second (third) the alkene material of modification is made in pelletizing, and the proportioning (weight percent) of colliery powder and poly-second (third) alkene is:
0%＜coal gangue≤50%, 50%≤poly-second (third) alkene＜100%.
The present invention utilizes trade waste-coal gangue production modification to gather second (third) alkene material, reduce cost about 60% than producing poly-second (third) alkene material, improved the technical features such as tensile strength, instant blasting pressure of material, can reduce the mining area coal gangue again simultaneously and increase and appropriation of land.
Further specify the present invention below by embodiment:
Embodiment one: coal gangue is crushed to particle diameter less than 61 microns (250 purposes account for 100%) with winnowing machine, and with colliery powder and polyethylene, softening agent mixing, weight percent is: colliery powder 30%, polyethylene particle 68%, softening agent 2% again.Then raw material send into kneader heat, dry, mediate, mixing by forcing machine again, form by tube drawing bench again after the pelletizing and draw modified polythene tube.
Embodiment two: it is 48 microns (300 orders) that coal gangue is crushed to particle diameter with winnowing machine, again with colliery powder and polypropylene, softening agent mixing, weight percent is: colliery powder 20%, polypropylene GRANULES 78%, softening agent 2%, then raw material send into kneader heat, dry, mediate, mixing by forcing machine again, make modified polypropene spare by the injection moulding machine moulding again after the pelletizing.
Embodiment one goods tubing and several technical performance index contrast tables of GB GB674-86 are as follows:
GB GB674-86 embodiment 1
Wall thickness (mm) 6.5 3.2
Caliber φ (mm) 110 110
Tensile strength (MPa) 〉=9.6 15.2
20 ℃ of water tests (MPa)
(moment burstpressures) 1.2 1.5
Claims (2)
1, a kind of second (third) alkene raw material that will gather heats kneading, and the method mixing, that pelletizing production modification gathers second (third) alkene is characterized in that adding colliery powder in poly-second (third) alkene raw material, and the weight percent of colliery powder and poly-second (third) alkene is:
0%＜coal gangue≤50%, 50%≤poly-second (third) alkene＜100%.
2,, it is characterized in that said coal gangue powder particle diameter is less than 61 microns according to the method for described poly-second (third) alkene of production modification of claim 1.
