Abstract
The invention discloses a preparation method of the spheric polymeric wax, which consists of the following steps: a. the granule materials are heated to the molten state in a reactor and continuously raise the temperature to 5 DEG C. to 200 DEG C.; b. the granule materials are extracted from the reactor and are pressed to 0.1MPa to 100MPa by a liquid loading device; c. the pressed air is purified and pressed to 0.1MPa to 20MPa by an air compressor; d. the pressed air meets the molten materials in the environment with temperature lower than the melt temperature and is sprayed to the microaggregate by a granulation plant. The method of the invention has convenient operation, stable material handling, high shaping rate and high finished product yield of the spheric or approximately spheric micro particles. Besides, the prepared polymeric wax is good in dispersion, resistant in scrap wounding and scratch and low in addition, which greatly reduces the cost manufacturer.
Description
Technical field
The present invention relates to the physical treatment field of wax or modified waxes, specifically a kind of preparation method of micro mist wax.
Background technology
Micro mist wax, or be called micronization wax and be widely used in printing-ink, paint, coating in the plastic-steel section bar, improves its surperficial resistance to marring, wear resistance, increase slippery, anti-ly after-tacks, does not fit, improves feel; Improve antiblocking, antifouling property, can control the glossiness of printing-ink, prevent the pigment sedimentation, cooperate inferior light powder production high-performance semigloss oil China ink and paint etc., become indispensable important auxiliary agent in the industrial circles such as paint, printing ink production.Most of micro mist wax is by polyethylene wax, Fischer-Tropsch wax, Poly Propylene Wax, tetrafluoroethylene and modified waxes thereof etc., makes by various micronization technologies, and some is that polyamide wax, Microcrystalline Wax, natural wax are by the micronization explained hereafter.
External micro mist wax mainly contains 3 kinds of approach manufacturings: the one, and by machinery or comminution by gas stream polishing, evaporation and precipitation, physical methods such as fusion; The 2nd, by chemical reagent, make the molecule that is in dissolved state generate the particulate of required particle diameter gradually, can be divided into dissolving and two kinds of dispersing method of emulsification; The 3rd, directly by polymerization or degraded preparation.As radiation cleavage system PTFE micro mist, controllable molecular weight PP, preparation PS micro mist wax, thermo-cracking, PMMA micro mist.The main at present physical method by mechanical disintegration is produced micro mist wax, out-of-shape, and bad dispersibility, the scratch resistance performance is undesirable, and addition strengthens, the cost height.Most of import micro mist wax product occupies the market share more than 95%, and price is expensive.
Summary of the invention
Goal of the invention of the present invention is for providing a kind of preparation method of spheric polymeric wax, and the micro mist wax of preparation has good dispersity, anti scuffing, the good advantage of scuffing performance.
Realize that foregoing invention purpose technical scheme is as follows:
A kind of preparation method of spheric polymeric wax, be made up of the following step:
A. the granulation material is heated to molten state in reactor, continues to heat up 5～200 ℃;
B. the granulation material is extracted out from reactor, and be forced into 0.1～100MP;
C. gas under pressure is purified, be forced into 0.1～20MP with air compressor machine;
D. make the gas of pressurization and the molten materials of pressurization, in being lower than the environment of melt temperature, converge, be injected into ball-shaped micro mist shape through prilling granulator.
In the aforesaid method, after the material fusion, the preferred continuation heated up 5～100 ℃, preferably the granulation material pumped up to 1～50MP among the step b, preferably forced air is forced into 1～10MP among the step c among the step a.
Granulation material among the present invention is a kind of or its arbitrary combination of paraffin, Microcrystalline Wax, synthetic wax, Fischer-Tropsch wax, polyamide wax, polyethylene wax, Poly Propylene Wax, palm wax, tetrafluoroethylene wax, or the mixing of their modified product.
The method of forming of the present invention, easy to operate, mass transport is stable, can require can regulate and control ratio of briquetting height, spheroidal or approximate circle ball-shaped micro powder finished granule yield height to gas and material pressurization according to the micro mist median size.The micro mist wax of present method moulding, particle are spheroidal or near spheroidal, good dispersity, and anti scuffing, scuffing, addition is low, reduces manufacturers's cost greatly.
Facility investment of the present invention is few, and is easy and simple to handle, need not add water in the production process, and the product that dispatches from the factory needn't be dry, and cost is corresponding lower, and does not add any auxiliary.

Embodiment
The invention will be further described below in conjunction with accompanying drawing, specific embodiment and Comparative Examples.
As shown in Figure 1, a kind of preparation method of spheric polymeric wax selects for use polyethylene wax as granulation material 1, and granulation material 1 is added in the reactor 2, is heated to molten state, continues to heat up 20 ℃; Fused granulation material 1 is extracted out from reactor 2, be forced into 5MP with pump 3; Gas under pressure 4 is purified, be forced into 10MP with air compressor machine 5; The gas 4 that makes pressurization and the molten materials 1 of pressurization are lower than in the environment of melt temperature and converge, and be injected into spheroidal micro mist wax 7 through prilling granulator 6 in prilling granulator 6.
