Description
Technical field
The invention belongs to plastic cement field, and in particular to a kind of wear resistant plastic particle and preparation method thereof.
Background technology
The definition (America Plastic TIA) of plastic cement：Mainly by carbon, oxygen, hydrogen and nitrogen and other organic or inorganic element institutes
Form, finished product is solid, is the liquid of molten in the fabrication process, therefore can be heated with nationality makes its fusing, plus-pressure make it
Flowing, cooling make its solidification, and are formed variously-shaped, and this huge and protean material group is referred to as plastic cement.And plastic cement
Plastic cement as its name suggests, is exactly fabricated to graininess by grain.
At present, many fields are all higher to the performance requirement of plastic grains, such as, it is wear-resisting, corrosion-resistant etc., still, pass
The performance of the plastic grains of system is difficult to meet all conditions, when meeting wearability, cannot meet corrosion resistance, because this is one
The presence of individual contradiction, in addition, its performance also receiving preparation method influences.
It is therefore proposed that a kind of wear resistant plastic particle is the problem of the invention to be studied.
The content of the invention
The main purpose of the application is to provide a kind of wear resistant plastic particle, can not expired simultaneously with solving existing plastic grains
Sufficient wearability and corrosion resistant problem.
To realize aforementioned application purpose, the technical scheme that the application uses includes：A kind of wear resistant plastic particle, the plastic cement
The chemical composition and content mass percent of particle be：
Wherein, the mass ratio of the ultra-high molecular weight polyethylene, glass fibre and polyamide is：5.8:1:0.8；It is described
The mass ratio of molybdenum disulfide and plasticizer is 1:1.4.
Further, the plasticizer is phthalic acid two (2- ethyl hexyls) ester.
Further, in addition to dispersant.
Further, the dispersant uses polyacrylic acid sodium salt and polyvinyl alcohol in mass ratio for 1:1 mixture.
Further, the mass percent of the molybdenum disulfide and polyamide is 1:1.3~1.7.
Further, the mass percent of the molybdenum disulfide and polyamide is 1:1.5.
In addition, the another technical solution of the present invention is：A kind of preparation method of wear resistant plastic particle, using claim
The chemical composition of 1 plastic grains, follow the steps below operation：
The first step, ultra-high molecular weight polyethylene being added in banbury and is kneaded, melting temperature is 170-180 DEG C, when
Between be 5-8 minutes；
Second step, glass fibre, molybdenum disulfide and colouring agent are added into 170-180 DEG C of mixer mixing temperature, time
For 3-4 minutes；
3rd step, polyamide, plasticizer are added into banbury, mixing time is 2 minutes, then extrusion sheet, through over cure
Change, classification is granulated, and obtains finished product.
Technical scheme more than, the beneficial effect of the application are：Wearability of the present invention is good, corrosion resistance is good, energy
Enough requirements for meeting wearability and corrosion resistance simultaneously.
With reference to following explanation and accompanying drawing, the particular implementation of the application is disclose in detail, specifies the original of the application
Reason can be in a manner of adopted.It should be understood that presently filed embodiment is not so limited in scope.In appended power
