5 particularly adapted for use as a pipe thread or hot joint compound. Thenature of this material will be fully understood in regard to both its manufacture and use from the following description. p
Pipe threador hot joint-compounds have been widely used in the past and while these compounds often produce a tight oint, there is great difficulty in breaking the joint, and the threads or, other surfaces are consequently often-damaged. My improved compound has the valuable property of retaining almost indefinitely its sealing and lubricating quali ties so that joints may be taken down with the greatest ease after long periods of severe service and with no damage to the con tacting surfaces.
I have found that the metallic salts of the sulfonic acids "are valuable ingredients for hot joint compounds. These sulfonic acids are made by extracting the oily layer resulting from the treatment of hydrocarbon oil with concentrated or fuming sulfuric acid with an organic solvent such as alcohol. The
salts are obtained by neutralizing the acids with alkali, usually soda, either before or after the removal of the solvent by evaporation. I may incorporate with the sulfonic material other products having the nature of fillers, lubricants, binders or agglutinants and diluents to produce the consistency and the special qualities which may be desirable for any particular use.
As an example of a composition contemplated in my invention, the following is given: 1
No. 1.-15O parts amorphous graphite, 7 5 parts zinc dust; 60 parts sodium sulphonate,
as described; 40 parts paraffin oil, 90 parts waste sulphite liquor, 10 parts water.
The paraflin oils may vary widely as to their properties but it is desirable for the oil to have a flash point sufficiently high to avoid danger of fire; oils with flash points from 150 F to 450 F are contemplated.
By waste sulphite liquor I refer to a waste Applicaticm filed. February 1, 1927. Serial No. 165,249.
product in the manufacture of paper pulp by the sulphlte process. This product is alkaline with glue-like properties and contains normally about of water. The sulphite liquor may be evaporated to a sticky: solid or semi-solid and may. beused as such inmy compositions, although in such case it would be better to add more water than if the sul-' phite liquor itself were used.
Other compounds are given as follows: No. 2.100- parts amorphous graphite,-5O parts sodium sulfonate, 50parts parafiin oil.
" No. 3-50 parts red lead, 85 parts amorphous graphite, parts sodium sulfonate,
40 parts paraifin oil.
N0. 4-"50 parts 1ron oxide, pulverized; 60 parts sodium sulfonate,4=0parts paraffin oil.
In the manufacture of my compositions, the
sulfonate is dissolved in the oil in a heated condition and the waste sulphite,if used,is
now. added. The fillers may now be thoroughly incorporated by a mechanical mixer or otherwise and the mass may be thinned by addition of either'water or oil.
