Problems solved by technology

However, as a result of crushing zirconium carbide crystals, the surface of the micronized zirconium carbide powder presents a high fracture surface and a sharp appearance, which is not conducive to the dispersion of the powder in the fiber, and it is easy to cause sharp protrusions of the zirconium carbide material on the surface of the fiber
The zirconium carbide material has high hardness, and the sharp protrusions will cause damage to the wire guide that transmits the fibers in the subsequent textile process, resulting in the unsmooth and continuous textile process

Abstract

The invention discloses a zirconium carbide composition used in a fiber material and a preparation method thereof. The zirconium carbide composition comprises the following components by weight: 79-89.5% of zirconium carbide, 0.5-1% of a metal oxide and 10-20% of resin. The preparation method of the zirconium carbide composition consists of: firstly, putting zirconium carbide powder in an oily solution to perform mechanical grinding, then using the metal oxide to fill the recess on a zirconium carbide surface to reduce the height difference on the zirconium carbide surface, and finally performing cladding with a resin soft material to form a relatively flat powder surface. The pointed appearance existing on the powder surface can be reduced or eliminated, thus avoiding the guide wire scratching damage problem generated in a follow-up spinning process.

Description

technical field [0001] The invention relates to the field of fiber application, more specifically to a zirconium carbide composition used in fiber materials and a preparation method thereof. Background technique [0002] Zirconium carbide powder is an important far-infrared radiation material. The crystallization of zirconium carbide is used to convert infrared energy into far-infrared rays. The higher the degree of crystallization, the better the effect of far-infrared radiation. In the prior art, many components of zirconium carbide are used as additives for far-infrared rays or heat-storing and heat-retaining fibers. However, zirconium carbide is a high-temperature crystalline material, and its crystals have high bonding strength. In the micronization process of zirconium carbide grinding, the crystals are broken into smaller crystal blocks due to the action of mechanical force. Although the particle size of zirconium carbide powder can be reduced, it is beneficial to ad...
