Description

PLASTIC INSULATINQ GGQIPBSETEQN.
1,183,6dl1n No Drawing.
To all whom it may concern:
Be it known that 1, Hum GROSSMANN, analytical chemist, a citizen of Switzerland, residing at Ober-Urdorf, near Zurich, Switzerland, have invented new and useful Improvements in Plastic Insulating Compositions, of which the following is a specification.
.The hitherto known filling and insulating materials, that is, insulating materials capable of being cast for electrotechnical purposes, have up till now only been put on the market inthe form of solid blocks which, before they can be used, have to be ground down with considerable expenditure of power and time for the purpose of melting.
The present invention relates to a filling and insulating material which obviates the above-named drawbacks as this material is put on the market in powder form, that is, in the most favorable condition for melting.
The new molding and insulating material consists at least of a resinous substance of low melting point and a substance whichincreases the insulating properties of the material and which does not fuse atthe melting point of the resinous substance, thetwo said substances being intimately mixed with one another.
The easily fusible resinous material may be, for example, resin, pitch, asphalt or the like, while the other substance, which increases the insulating properties, may be, for example, glass, porcelain, marble, talc, sand, heavy spar or the like. The latter substance also Tfulfils incidentally the further purpose of maintaining the material mpowder form, since the resinous material when pulverized very easily fuses or cakes together when kept for a long time. For the preparation of the filling and insulating material, both substances are intimately mixed with one another in a finely powdered form. For example,- of powdered colophonium and 50% of pulverized glass may be employed for the mixture. The relative quantities of the two substances can, however, be altered within .wide limits, ac-
cording to the nature of the substances used and the particular purpose or use desired.
Specification of Letters Patent.
Application filed August 5, 191%.
Patented lday 1 8, Serial No. esaaoe.
By alteration of the relative quantities it is powder form may be added with advantage.
This material may be, for example, parafiin wax, carnauba wax, montan wax or the like, and the quantity used may also be varied within fairly wide limits.
Assuming the above named substances to be used, the following proportions for the mixture may be used:
I. 45% powdered colophonium.
415% powdered glass.
10% powdered paraflin.
80% powdered colophonium. 60% powdered glass.
10% powdered parafiin.
60% powdered colophonium. 25% powdered glass.
15% powdered parafiin.
The filling and insulating material described permits of a much simpler and more convenient handling in use than the mold- III.
:ing and insulating materials hitherto used.
The new filling and insulating material also oflers the further advantage that it can be produced at less cost.
I claim:
1. The herein described filling and insulating material for electrotechnical. purposes consisting of powdered colophonium.,
powdered glass, and powdered wax; all sub stances being intimately mixed together, substantially as set forth.
2. The herein described filling and iii-- sulating material for electrotechnical purposes consisting of about 30 to 60% powdered colophonium, 25 to 60% powdered glass, and 10 to 15% paraffin wax; all substances being intimately mixed together,
substantially as described.
3.
