Anti-electrostatic ceramic material, preparation method thereof and firecrackers lead knitting needle made of material

Abstract

The invention discloses an anti-electrostatic ceramic material which comprises the following components in percentage by weight: 68-80 percent of yttria stabilized zirconia, 1-3 percent of silicon dioxide, 10-14 percent of tin oxide, 7-11 percent of zinc oxide, 1-2.5 percent of silicon 1-2.5 percent of silicon carbide. The preparation method of the ceramic material comprises the following steps of: firstly, mixing various raw materials in ultrathin powder state by a ball mill; then drying; melting and blending the dried mixed raw materials with an organic binder according to a mass ratio of (4-9):1; injecting and forming particles obtained by melting and blending to obtain a ceramic blank; and degreasing and sintering to obtain an anti-electrostatic ceramic material. In the method, the firecrackers lead knitting needle is injected and formed by a die. The anti-electrostatic ceramic material and the firecrackers lead knitting needle thereof have the advantages of electrostatic resistance, abrasion resistance, good anti-bending performance, simple preparation process, lower cost, and accurate size of a prepared ceramic product without post-processing.

Description

technical field [0001] The invention relates to a ceramic material and a preparation process thereof, in particular to a ceramic material with yttria-stabilized tetragonal zirconia as a matrix, a preparation process thereof and a prepared firecracker lead wire knitting needle. Background technique [0002] In daily life, especially in the dry winter in the north, the phenomenon of "static electricity" occurs from time to time, which brings great harm to people's body and spirit, affects physiological balance, and accelerates the aging of the human body. The phenomenon of "static electricity" is also very common in the information industry, textile industry, petrochemical rubber and other industrial fields. The accumulation of electrostatic charges will not only interfere with the use of precision instruments, but also affect production and life. casualties. [0003] Take fireworks and firecrackers as an example. The manufacture of fireworks and firecrackers is a high-risk i...

Problems solved by technology

Although the resistivity of these disclosed antistatic ceramic materials has met the antistatic requirements, the preparation method is complicated and the cost is high, and some require hot pressing or hot isostatic pressing sintering

In addition, the antistatic ceramic materials prepared by these methods have poor mechanical properties, which restricts their application.
