Abstract

Parts made from unvulcanized butyl rubber are spliced and vulcanized by contacting them under pressure, cooling the joint thus formed to a temperature lower than 50 DEG F., fixing the joint in the vulcanizing position by contacting it with a surface of the shape and size of the desired part after vulcanization, and heating to effect vulcanization. Cooling may be effected by means of a mixture of solid carbon dioxide and acetone which chills the joint to a temperatue of 0-40 DEG F., the joint being dipped into the solution for 5-60 seconds, or the solution may be p sprayed or painted. In an example an inner tube is made by extruding a mix containing butyl rubber, carbon black, zinc, oxide, mineral oil, mercaptobenzthiazole, tetramethyl thiuram disulphide, and sulphur, cutting to length, inserting a valve, butt splicing the ends, cooling for 10 seconds in the carbon dioxide and acetone mixture, placing in a watch case mould, inflating to fill the mould while still chilled and then vulcanizing at 300-400 DEG F. Air bags may be made similarly.
