Problems solved by technology

At present, micro-powder wax is mainly produced by physical methods of mechanical crushing, which has irregular shape, poor dispersion, unsatisfactory scratch resistance, increased dosage, and high cost.
Most imported micronized wax products occupy more than 95% of the market share, and the price is relatively expensive

Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings, specific embodiments and comparative examples.

[0019] As shown in Figure 1, a preparation method of spherical micropowdered wax uses polyethylene wax as the granulation material 1, puts the granulation material 1 into the reactor 2, heats it to a molten state, and continues to heat up 20°C; The granular material 1 is extracted from the reactor 2, pressurized to 5MP with the pump 3; the pressurized gas 4 is purified, and pressurized to 10MP with the air compressor 5; the pressurized gas 4 and the pressurized molten material 1 are produced In the granulation device 6, they meet in an environment lower than the melting temperature, and are sprayed into a spherical micropowder wax 7 through the granulation device 6.

[0020] The comparative example is the micronized wax prepared by the mechanical method commonly used at present, and the performances of the specific example...

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 [0001] The invention relates to the field of physical treatment of wax or modified wax, in particular to a preparation method of micronized wax. Background technique [0002] Micronized wax, or micronized wax, is widely used in printing inks, paints, coatings, and plastic steel profiles to improve the surface's scratch resistance, wear resistance, increase slip, anti-sticking, non-fitting, and improve hand feeling ; Improve anti-blocking and anti-fouling properties, can control the gloss of printing inks, prevent pigments from settling, and produce high-performance matt inks and paints with matt powders. It has become an indispensable and important assistant in industrial fields such as paint and ink production. agent. Most of the micronized waxes are made of polyethylene wax, Fischer-Tropsch wax, polypropylene wax, polytetrafluoroethylene, and their modified waxes, etc., through various micronized processes, and some are polyamide waxes and microcrystalline...
