Abstract

The invention discloses an ultrafine micro wax powder and a preparation method thereof. The wax powder is made of the following components in percentage by weight: 75% to 85% of paraffin, and 15% to 25% of silicon substance; wherein the silicon substance is made of one or more of silicon sand, silicon micro powder, and organic silicon. The preparation method comprises the following steps: (1) weighing the components according to the weight ratio mentioned above, grinding the paraffin and the silicon substance at a room temperature, softening the paraffin for 10 to 15 minutes to make the paraffin fully cover the silicon substance; (2) grinding the mixture at a temperature of 0 to 10 DEG C so as to obtain the ultrafine micro wax powder. The prepared ultrafine micro wax powder has the advantages of excellent matting property, transparency, smooth surface, good hand feeling, narrow particle size distribution, normal shape, scratching resistant performance, high purity, and good dispersibility.

Description

technical field [0001] The invention belongs to the field of mineral preparation, and in particular relates to an ultrafine wax powder and a preparation method thereof. Background technique [0002] Paraffins have a high molecular weight and therefore a high boiling point, and to date they are produced from the residues of vacuum distillation of petroleum, especially in the manufacture of lubricating oils (paraffin residues), and from deposits during the extraction, transportation and storage of petroleum , and are process-expensive and result in increased costs due to multi-step processes such as deasphalting, solvent extraction, deparaffinization, deoiling and refining. [0003] Paraffin waxes are mainly added as mixing ingredients in mixtures of alkanes or waxes. Its addition generally accounts for at most 5% of the total amount. The addition of this mixture can firstly increase the hardness and melting point and improve the plasticity and oil cohesion. Typical applica...
