Abstract
The invention discloses a polyethylene drainage pipe material and a preparation method thereof. The polyethylene drainage pipe material comprises the following raw materials in percentage by weight: 70 percent of high-density polyethylene (HDPE), 20 percent of enhancing and toughening aid, 5 percent of glass fiber, 3 percent of color master, and 2 percent of de-foaming agent; and the polyethylene drainage pipe material is prepared by mixing and extrusion molding of the raw materials. The polyethylene drainage pipe material and the preparation method are economic and practical; under the condition that the integral performance of the pipe material is ensured, the cost is reduced as much as possible, and the competitiveness is improved; and different products with qualified mechanical properties can be prepared by multiple types of plastic processing on the premise that the original wide processing adaptability of the HDPE is kept, and the compressive property of the pipe material is improved.
Description
Technical field
The invention belongs to polyvinyl piping materials, be specifically related to a kind of polyethylene drainage pipe and preparation method thereof.
Background technology
Polyethylene tube has the advantages such as erosion resistance is strong, wholesomeness good, snappiness is good, light weight, is widely used in plumbing and heat exchange, heating pipe system field.Except having above advantage, the polyvinyl piping materials pipeline also should have preferably rigidity and supporting capacity.In order to reach customer demand, in the polyvinyl piping materials preparation, although there is the compounded mix of employing to carry out the research of modifying plastics at present, but the balance in the research between the fundamental property of few consideration tubing and mechanical property, processing characteristics, the compressive property, thereby cause the polyvinyl piping materials performance, particularly long-term hydrostatic test can't reach the requirement of standard.
Summary of the invention
The problems referred to above that exist in order to overcome the prior art field the object of the invention is to, and a kind of polyethylene drainage pipe and preparation method thereof is provided, and solve the problem that the long-term hydrostatic test of present polyethylene drainage pipe can't reach standard-required.
Polyethylene drainage pipe provided by the invention, feed composition are as follows by weight percentage: HDPE70% strengthens toughening auxiliary agent 20%, glass fibre 5%, look mother 3%, clear infusion 2%, above-mentioned raw materials makes described polyethylene drainage pipe through mixed refining, extrusion moulding.
The preparation method of polythene drainpipe comprises the steps,
(1) preheating and drying: in vacuum drying oven, will dry by the various raw material preheatings that predetermined proportion prepares;
(2) mixing raw material: adopt stirring mixer, will be extremely even by the various raw material stirring that predetermined proportion prepares;
(3) extrusion moulding: the raw material that mixes is dropped into forcing machine, extruding pipe material;
(4) vacuum sizing: adopt the tubing vacuum sizing of vacuum machine to extruding;
(5) cooling forming: adopt pipe cooler that the tubing of extrusion moulding is carried out cooling forming.
Polyethylene drainage pipe provided by the invention and preparation method thereof, its beneficial effect is that this polyethylene drainage pipe keeps HDPE extensive flexibility of operation originally, can carry out polytype plastic working, make the qualified different goods of mechanical property, improved the compressive property of tubing; The polyethylene drainage tube preparation method is economical and practical, and under the condition that guarantees the tubing overall performance, has reduced as much as possible cost, has improved competitive power.
Embodiment
Below in conjunction with embodiment, to polyethylene drainage pipe provided by the invention and preparation method thereof, be described in detail.
Embodiment
Polyethylene drainage pipe of present embodiment and preparation method thereof, the feed composition of polyethylene drainage pipe is as follows by weight percentage: HDPE70%, strengthen toughening auxiliary agent 20%, glass fibre 5%, look mother 3%, clear infusion 2%, above-mentioned raw materials makes described polyethylene drainage pipe through mixed refining, extrusion moulding.Before the start, need to carry out pre-heating temperature elevation in 2 hours in advance, check simultaneously whether each warm area temperature probe work is sensitive reliable, and whether measured temperature conforms to actual temperature; The various raw material stoving that in vacuum drying oven, will prepare by predetermined proportion according to technical recipe; According to prescription beginning batch mixing, pour into and wait use after stirrer stirs; After forcing machine was warming up to design temperature and is incubated for some time, the side can use; Start forcing machine, according to producing actual required adjustment engine speed, note simultaneously the variation of each several part, and adjust a mouthful die clearance, make the discharging uniformity; Start vacuum machine, make the tubing sizing; Pipe cooler carries out cooling forming to the tubing of extrusion moulding.For the performance that makes production line is brought into play, the maximum economic rate of production (MERP) should not surpass 80% of motor maximum speed, under the condition that guarantees the tubing overall performance, has reduced as much as possible cost, has improved competitive power; Keep HDPE extensive flexibility of operation originally, can carry out polytype plastic working, make the qualified different goods of mechanical property, improved the compressive property of tubing.
