Description
Technical field
What the present invention relates to is a kind of polyethylene, specifically refers to modification regeneration polyvinyl piping materials, pipe fitting PP Pipe Compound.
Background technology
Poly English name is polyethylene, and is called for short PE.This polyethylene is a kind of thermoplastic resin that ethene makes through polymerization.
The main production method of China's olefin product is to utilize petroleum naphtha to be prepared from, and China is the country of " the rich coal of few oily deficency ", and this situation will certainly cause the deficiency of China's olefin product, and then causes polyethylene to have raw material and cost pressure.
Summary of the invention
The object of the invention is to solve existing modified polythene tube, the pipe fitting PP Pipe Compound all adopts new polyethylene to make, thereby cause consuming the problem that polyethylene is more, production cost is higher, provide a kind of polyethylene that utilizes recovery to produce cheaply as the raw material manufacturing and for the production of modification regeneration polyvinyl piping materials, the pipe fitting PP Pipe Compound of tubing, pipe fitting.
Realize that technical scheme of the present invention is as follows:
Modification regeneration polyvinyl piping materials, pipe fitting PP Pipe Compound, mainly the component by following weight percent forms:
Further, described recycle polyethylene is the sheet stock that waste and old polyethylene obtains after fragmentation, cleaning, oven dry, homogenizing.For fear of other impurity that are blended in this waste and old polyethylene it is impacted, other light-weight articles that also utilize gas blower will be mixed in the waste and old polyethylene in the process of oven dry blow out, and described light-weight articles is the materials such as label of plastics.
Further, the fineness of described calcium carbonate is 2400～2600 orders.
The preparation method of modification regeneration polyvinyl piping materials, pipe fitting PP Pipe Compound is made of following steps:
(1) polyethylene, recycle polyethylene, toughner, talcum powder, calcium carbonate, anti-impact modifier, dicumyl peroxide, antioxidant 1010, silane coupling agent, polyethylene wax, calcium stearate, pigment mix under high-speed condition, make the material that is mixed;
(2) extrude and namely make finished product with the forcing machine material that will be mixed.
For the more effective mixing of carrying out each component of energy, all components mixes in proportioning machine in the described step (1).
In order better to realize the present invention, the forcing machine that adopts in the described step (2) is twin screw extruder.
As a kind of preferred, described finished product granulation.
The present invention has the following advantages and beneficial effect:
1, the present invention utilizes the waste polyethylene of recovery to do raw material to prepare new tubing, pipe fitting PP Pipe Compound, utilize recycle polyethylene to substitute new polyethylene, and then the new existing raw material of polyethylene and cost pressure are produced in alleviation, and the present invention not only makes waste polyethylene be recycled utilization, cost is saved greatly, the destruction of also having avoided waste polyethylene to bring to environment is effectively realized the function of environmental protection; Simultaneously, by detecting data as can be known, do the dedicated modified polyethylene material of tubing, pipe fitting that the raw material preparation makes new advances by waste polyethylene among the present invention and compare with existing modified poly ethylene material, its performance is more superior, extremely is fit to apply.
2, fragmentation, cleaning, oven dry and homogenizing be need carry out before waste polyethylene uses among the present invention, impurity in the waste polyethylene, quality and the various functions of the modified poly ethylene that effective utility waste polyethylene is prepared effectively removed by above-mentioned steps.
3, the fineness of calcium carbonate is preferably 2500 orders among the present invention, use calcium carbonate as the packing material among the present invention, can effectively reduce production costs, and by the calcium carbonate under this fineness, this calcium carbonate and other materials are mixed, and then improve the quality of the finished product that the present invention makes, simultaneously, but the shock resistance of Effective Raise finished product of the present invention also.
4, adopt preparation method of the present invention, effectively each material among the present invention is mixed, and adopt method of the present invention to compare with other modified poly ethylenes preparation method, operate more simple, production efficiency is higher, and the present invention need manually still less, can be completely achieved machinery production, greatly save cost.
5, the present invention adopts twin screw extruder, have fricative heat is less, material is suffered shearing relatively evenly, the transport capacity of screw rod is large, extrusion capacity is more stable, material residence time progress and make all components mix more uniformly advantage in machine barrel, and then efficient and the quality of effectively assurance production, satisfy substantially user's demand.
6, finished product granulation agent among the present invention can be when using particle of the present invention to make tubing, pipe fitting, and hot melt institute energy requirement is lower, and the waste of the energy when effectively avoiding utilizing finished product of the present invention to make tubing, pipe fitting reaches the purpose of saving; Simultaneously, the transportation storage still less is convenient in the space that this granule takies in the process of storage.
