Preparation method of sepiolite-tetrapod zinc oxide whisker composite material

Abstract

The invention relates to a preparation method of a sepiolite-tetrapod zinc oxide whisker composite material. Sepiolite has very high adsorption performance and good dispersing performance and can be taken as a carrier and a framework of tetrapod zinc oxide whiskers, and respective use performance is not influenced. The preparation method comprises steps as follows: the sepiolite is dissolved in ethanol, methanol or hydrogen peroxide, is stirred uniformly and dried after separation, and sepiolite powder is obtained; the sepiolite powder and zinc powder are mixed, dissolved in distilled water, ethanol, methanol or hydrogen peroxide and stirred and mixed uniformly; a solid mixture obtained after separation is placed in a drying oven for drying; dry powder is placed in a high-temperature stove for calcination treatment, and the sepiolite-tetrapod zinc oxide whisker composite material is obtained. The prepared composite material has performance including wear resistance, strength enhancement, damping performance, slip resistance, nose reduction, ageing resistance, antistatic property, antibacterial property and the like and can be widely applied to materials such as a coating, an antibacterial material, an antistatic material, a wear-reducing and wear-resistant material and the like, the operation technology is simple, and the economic cost-performance ratio is high.

Description

technical field

[0001] The invention relates to a preparation method of a sepiolite-tetra-needle zinc oxide whisker composite material, and belongs to the field of composite materials. Background technique

[0002] The four-needle zinc oxide whiskers have excellent properties unmatched by ordinary zinc oxide, and it is easy to achieve uniform distribution in the matrix material to improve the physical properties of the material, and at the same time endow the material with a variety of unique functional properties. The four-needle zinc oxide whiskers have the properties of wear resistance, reinforcement, shock absorption, anti-skid, noise reduction, anti-aging, anti-static, anti-bacterial and other properties, and are widely used in many fields. At present, most of the four-needle zinc oxide whiskers are prepared by using zinc powder as raw material. However, during the preparation process, the zinc oxide generated on the surface of the zinc powder will form a coating film, ...
