Description
Technical field:
The present invention relates to a kind of large-bore plastics blow-off line PP Pipe Compound and preparation method thereof.
Background technology:
For a long time, the underground heavy caliber blow-off line of domestic city mainly adopts concrete and cast iron manufacturing, the many defectives of ubiquity: poor, the easy seepage of stopping property, heavy, constructional difficulties, inner wall coarse, liquid flowing resistance are adhered to dirt greatly, easily and are caused obstruction, and they are rigid pipe simultaneously, easy embrittlement when bearing load or land subsidence, and life and industrial sewage that the buried pollution discharge pipe is carried usually be corrosive liquid, and especially serious to the cast-iron pipe corrosion, lack work-ing life.If then cost is too high to adopt the all-plastic pipeline, therefore the trade wastes such as flyash with power plant are stopping composition, design by rational formula, can obtain meeting the non-pipe line made up of full plastics PP Pipe Compound of blow-off line service requirements, not only have extremely low cost and good ring stiffness, and the trade wastes such as a large amount of flyash of power plant are carried out utilization of waste material, eliminate environmental pollution.
Summary of the invention:
Purpose of the present invention is exactly in order to overcome the defective that above-mentioned prior art exists, and provides a kind of and has reduced cost significantly and improve ring stiffness, can satisfy heavy caliber and bury PP Pipe Compound that ground plastics blow-off line uses and preparation method thereof.
Purpose of the present invention can be achieved through the following technical solutions: large-bore plastics blow-off line PP Pipe Compound, it is characterized in that, and comprise following component and content (weight part):
High density polyethylene(HDPE) 30-60
Toughner 10-30
Weighting agent 15-45
Coupling agent 1-10
Oxidation inhibitor 0.1-2
Lubricant 1-10
Described large-bore plastics blow-off line PP Pipe Compound is characterized in that described toughner is the polyolefins elastomerics.
Described large-bore plastics blow-off line PP Pipe Compound is characterized in that described weighting agent is a flyash.
Described large-bore plastics blow-off line PP Pipe Compound is characterized in that, described coupling agent is silicane or titanate ester compound.
Described large-bore plastics blow-off line PP Pipe Compound is characterized in that described oxidation inhibitor is phenolic antioxidant.
Described large-bore plastics blow-off line PP Pipe Compound is characterized in that, described lubricant is paraffin, stearic acid compound.
The preparation method of large-bore plastics blow-off line PP Pipe Compound, it is characterized in that, at first get the raw materials ready by described component of claim 1 and content (weight part), with weighting agent, coupling agent, oxidation inhibitor, lubricant, toughner blend extruding pelletization, obtain filled toughening masterbatch, then with filled toughening masterbatch and high density polyethylene(HDPE) after disperseing blend, by the twin screw extruder fusion, mixing, extrude, cool off, after dry, pelletizing and the packing, obtain product.
Compare with existing conventional art, the present invention greatly reduces cost on the one hand and has improved ring stiffness by selecting suitable material prescription and processing step, on the other hand, can carry out utilization of waste material to the trade wastes such as a large amount of flyash of power plant.
