SEMICONDUCTOR POLYMERIC COMPOUND BASED ON LAMPBLACK,POLYMERIC SEMICONDUCTOR BODY, AND METHODS OF MAKING THE SEMICONDUCTOR POLYMERIC COMPOUND AND THE POLYMERIC SEMICONDUCTOR BODY |
摘要 |
<p>The method of making a semiconductor polymeric compound includes an "A" pha se consisting of preparing a mixture of a polymeric matric consisting essential ly of about 60% by weight low density polyethylene and about 8.5% by weight ethylene vinyl acetate based on a total amount of the polymeric compound to be prepared with about 20% by weight of a conductive lampblack with a porous structure and about 4.0% by weight of a spreading agent consisting of calcium stearate, about 3 by weight of an antioxidant, a nd about 0.5% of a coupling agent consisting of calcium titanate; and a "B" phase includin g incorporating the conductive component in the polymeric matrix by the steps of spreading t he mixture using "bamburg" type intermittent mixers under process conditions to obtain a high rate of lampblack shearing and homogenizing of a sheared lampblack and spreading and coupling agent portion. A semiconductor body according to the invention is made by extruding and calendering the semiconductor polymeric compound with lampblack aggregations having a high degree of shearing and low degree of orientation.</p> |
