Description
Technical field
The invention belongs to smart wax preparation field, be specifically related to a kind of method improving Fischer-Tropsch wax colourity.
Background technology
Fischer-Tropsch wax is methylene radical polymkeric substance, is the alkane of hydrocarbon-based synthetic gas or Sweet natural gas synthesis.Fischer-Tropsch wax can be applied in plastic working, as injection moulding, extrudes and granulation industry.Fischer-Tropsch wax, in Masterbatch and modified plastics production process, contributes to the dispersion of filler and outstanding slipping when batch mixing.The external lubricant of PVC can be used as, low-viscosity can improve the production rate of product, the dispersion contributing to color stuffing when batch mixing has especially in the extruding of high viscosity systems appoints preferably, 40--50% fewer than common PE wax addition, and can significantly improve product surface gloss.When using heavy colour, the Fischer-Tropsch wax of fusing can soak dyestuff effectively, reduces and extrudes viscosity.When being used in ink with microgranular powder, wear resistance, the crease resistance of application material can be improved.When being applied in coating, can corrugation effect be played, striped and water wave corrugation effect can be formed when micronised state uses.Adding powder coating resin, in extrusion, playing the sliding effect of Fischer-Tropsch, can screw torque be reduced, reduce energy consumption and enhance productivity.Fischer-Tropsch wax is the desirable synthetic wax that EVA based melt adhesive uses.Dystectic wax can improve the thermotolerance of tackiness agent and quick-drying but low colourity, low-quality Fischer-Tropsch wax grain can only limit and produce for industrial chemicals, and high chroma, high-quality Fischer-Tropsch wax product are monopolized by offshore company.If the quality of Fischer-Tropsch wax effectively can not be improved, the application in industries such as printing ink paint, plastic working, sizing agents will certainly be had influence on.
Summary of the invention
The present invention overcomes the deficiencies in the prior art, and to be solved is the colourity how improving Fischer-Tropsch wax, thus widens the range of application of Fischer-Tropsch wax, increases economic efficiency.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is:
Improve a method for Fischer-Tropsch wax colourity, comprise the step of continous way molecular distillation, and refining step; In the step of described continous way molecular distillation, be raw material with Fischer-Tropsch wax, distillation condition is: absolute pressure vacuum is 1Pa, and temperature of reaction is 300 DEG C; In described refining step, using atlapulgite as active substance, purification condition is: the mass ratio of atlapulgite and Fischer-Tropsch wax is 1:55-1:50, and temperature is 160-180 DEG C, and stirring bleaching time is 0.5-1h.
Preferably, in described distillation condition, be heated to 300 DEG C by heat-conducting oil furnace, and regulate holding temperature to stablize by boiler.
Preferably, in described distillation condition, adopt vapo(u)r blasting pumping set and two-stage Roots vaccum pump, ensure that absolute pressure vacuum is 1Pa.
The beneficial effect that compared with prior art the present invention has is: the colourity that improve Fischer-Tropsch wax, has widened the range of application of Fischer-Tropsch wax, has improve economic benefit.
