Description
Technical field
The present invention relates to fine chemistry industry polymer materials technical field, particularly relate to a kind of preparation method of composite polyethylene wax.
Background technology
Polyethylene wax (PE wax) is a kind of industrial chemicals, and its molecular weight is at about 2000-4000, and fusing point is between 70-105 DEG C, and the quality of polyethylene wax is white little microballon or in the form of sheets.It is applied widely, the demand that molecular weight and fusing point can be different according to client, composite obtained in three kinds of raw materials.Such as, as dispersion agent in colour batch processing, with the resin such as polyethylene, polyvinyl chloride, polypropylene, there is good intermiscibility, there is very excellent external lubrication and internal lubrication effect; Its photostabilization and chemical property very well, can be used as the carrier of pigment, can improve the wear resistance of paint, ink, improve the dispersiveness of pigment and filler; Various hot melt adhesive can also be used for, thermosetting powder coating(s), traffic marking paint, paint marking, as dispersion agent, have good anti-settling effect, and make goods have good gloss and stereoscopic sensation.
Producing polyethylene wax generally uses high score weight northylen as main raw material, after adding other auxiliary material, made by a series of scission reaction, scission reaction is a ring of most critical in polyethylene wax production process, but the price of high-molecular polythene is higher, and cracking polyethylene belongs to high-risk production technique, higher using its cost as raw material production polyethylene wax.
Because above-mentioned defect, the design people, actively in addition research and innovation, to founding a kind of preparation method of composite polyethylene wax, make it have more utility value in industry.
Summary of the invention
For solving the problems of the technologies described above, the object of this invention is to provide a kind of preparation method of the composite polyethylene wax reduced costs.
The preparation method of a kind of composite polyethylene wax that the present invention proposes, comprises the following steps:
(1) following component is prepared by mass percent: Fischer-Tropsch wax 1-80%, the mixture 10-80% of PE low molecular polymer and polypropylene oligomers, liquid hydrogenated oil 1-80%;
(2) three kinds of components in step (1) are mixed and stir 1-10 minute at 120-160 DEG C;
(3) by the mixing liquid cooling also moulding in step (2).
Further, the type of cooling in step (3) is water cooling, uses steel band water cycle tablets press that cooled polyethylene wax is sprayed into half rounded grain after cooling.
Further, the type of cooling in step (3) is water cooling, uses steel band or cylinder water cycle slicing machine that cooled polyethylene wax is cut into sheet after cooling.
Further, the type of cooling in step (3) is air cooling, uses spray Zhu Ta that cooled polyethylene wax is sprayed into microballon shape or powdery after cooling.
By such scheme, the present invention at least has the following advantages: use Fischer-Tropsch wax to replace cracking polyethylene to prepare polyethylene wax, its cost is lower, and by regulating the mixture of Fischer-Tropsch wax, PE low molecular polymer and polypropylene oligomers, the different specific weight of liquid hydrogenated oil three kinds of components, the polyethylene wax of different molecular-weight average and fusing point can be obtained, may be used for different purposes.
Above-mentioned explanation is only the general introduction of technical solution of the present invention, in order to better understand technique means of the present invention, and can be implemented according to the content of specification sheets, be described in detail as follows below with preferred embodiment of the present invention.
