The preparation method is characterized in that after PE and PTFE resin is radiated by the radiation technology, the micronization wax is prepared by a crushing process. The preparation method comprises the following specific steps of a) radiating the PE and PTFE resin in a radiation environment by radioactive rays; b) feeding the radiated PE and PTFE resin and auxiliaries in a millstone crusher to be coarsely crushed; c) performing airflow crushing for the coarsely crushed materials by an airflow crusher at normal temperature; and d) adjusting a size grading device of the airflow crusher to prepare the PE/PTFE mixed micronization wax.

Technical field
The present invention relates to a kind of preparation method of macromolecular material, particularly the UV light-curable ink is with the preparation method of PE/PTFE admixed finepowder wax.
Background technology
The UV light-curable ink is the new and high technology that developed recently gets up with PE/PTFE admixed finepowder wax investigative technique, generally calls ultramicron to particle diameter less than the particle of 0.5 μ m, is called particulate below the 20 μ m, and the aggregate of ultramicron is called ultrafine powder.Micro mist wax preparation has at present mainly contained 3 kinds of approach abroad: the one, set out by corase particles, with the method for physics such as mechanical crushing method and fusion method; The 2nd, utilize the effect of chemical reagent, make the molecule of the various dispersities of formation grow up to the big or small particulate of expectation gradually, the 3rd, directly regulate polymerization or degraded preparation.Because the UV light-curable ink will be present in the UV light solidifying coating surface with the discrete particles form with polyethylene/polytetrafluoroethylene (PTFE) admixed finepowder wax, reach the purpose that reduces the coating coefficient of friction.When the object strikes coating surface, the tendency of sliding is reduced friction and polished tendency greater than scratching tendency, has regulated the persistence of the required gloss of coating.The use of PE/PTFE admixed finepowder wax simultaneously will greatly increase lubricity, hardness, anti-after tack and rub resistance and the scratch resistance that light-curable ink is filmed.So development UV light-curable ink has certain degree of difficulty with the technology of PE/PTFE admixed finepowder wax, and strict to the control ratio of diameter of particle size.
Summary of the invention
The objective of the invention is provides a kind of even particle size distribution for the deficiency that solves above-mentioned prior art, and the high UV light-curable ink of production efficiency is with the preparation method of PE/PTFE admixed finepowder wax.
To achieve these goals, the UV light-curable ink that the present invention designed is with the preparation method of PE/PTFE admixed finepowder wax, it is characterized in that it carries out radiation with PE, PTFE resin with ray technology after, be prepared from through disintegrating process again, concrete steps are following:
A) PE, PTFE resin are carried out radiation with radioactive ray in radiation environment;
B) PE after the radiation, PTFE resin resin and auxiliary agent are dropped into the mill pulverizer and carry out coarse crushing;
The material that c) will pass through coarse crushing carries out the air-flow pulverizing with airslide disintegrating mill at normal temperatures;
D) the grading device of adjusting airslide disintegrating mill makes PE/PTFE admixed finepowder wax.
Radiation environment in the step a) is vacuum, air or inert gas, and radioactive ray are r ray or electron beam, and this radiographic source is 60Co or 137Cs, and the dose of radiation of radioactive ray is more than 100KGy.Auxiliary agent in the step b) is anti-oxidant and pigment, and PE: PTFE: the mass ratio of auxiliary agent=1: 0.1～0.5: 0.1～0.3.The pressure of the airslide disintegrating mill in the step c) is 900KPa～1200KPa.The UV light-curable ink of airslide disintegrating mill in step d) preparation with the particle diameter of PE/PTFE admixed finepowder wax less than 3.5 μ m.
At this, the part by weight of anti-oxidant and pigment is 1: 10, and pigment is mainly inorganic pigment, and the purpose of adding pigment is in order to satisfy the demand of client to different purposes.
The UV light-curable ink that the present invention obtains is compared with traditional method with the preparation method of PE/PTFE admixed finepowder wax, the PE/PTFE admixed finepowder wax even particle size distribution of its preparation, and particle diameter is controlled, and whole crushing process energy consumption is low, and production efficiency is high.
