Abstract
Electrical insulator bodies of various shapes are manufactured from inorganic powders and binders by a novel process comprising the steps of (1) maintaining in an agitated state the inorganic powders having a size between about 0.040 mm. and 1 mm., (2) spraying onto said agitated powders up to 10 per cent by weight of a binder consisting essentially of a homogenous fluid mixture of an epoxy resin and hardener, (3) molding the resulting mixture, and (4) hardening the molded mixture at a temperature not exceeding 160.degree. C., thereby producing a compact ceramic insulator material.
Claims9
A process for manufacturing electrical insulator bodies of various shapes from at least 90% crystalline inorganic mineral powders and binders which comprises the following steps:
- 1. maintaining in an agitated state the inorganic powders having a size between 0.040 mm and 1.0 mm;
- 2. spraying onto said agitated powders at elevated temperature sufficient to liquefy the binder, up to 10 percent by weight of total mixture of a binder consisting essentially of a homogenous fluid mixture of an epoxy resin and hardener so as to form a granular mass;
- 3. molding the resulting mixture;
- and
- 4. Hardening the molded mixture at a temperature not exceeding 160.degree. C., thereby producing a compact dense, nonporous ceramic insulator material.
