Title: Improvements in the manufacture of rubber
IPC: C08C3/00
Filed: 1950-06-13
Abstract: A process for the manufacture of rubber e.g. air dried sheet rubber, spray-dried rubber, powdered rubber and especially pale cr<\>zepe rubber from latex which may be diluted and mixed with sodium bisulphite including the step of treating the latex or coagulum with aryl or alkyl mercaptan e.g. xylyl mercaptan or b  naphthyl mercaptan or substances liberating mercaptans or their active radicals e.g. zinc b -naphthyl mercaptide, sodium b  naphthyl mercaptide, thioglycollic acid, 0.01-dibenzamidodiphenyl disulphide, dodecylmercaptan in small proportions not exceeding 0.1 per cent by weight calculated on the rubber insufficient to effect appreciable softening of the rubber, but effective to bleach the resulting product.  The process of bleaching is facilitated by the presence of peroxide or by bubbling air or oxygen through the latex.  In an example 50 litres of latex of clone "Prang Besar 186" diluted to 20 per cent w/v dry rubber content is mixed with a solution containing 50 grms of sodium bisulphite and is then mixed with an emulsion containing 5 grms of xylyl mercaptan.  After thorough mixing of these ingredients 40 grms of formic acid in 8 litres of water are added, stirred and the mixture left for 12 hours to coagulate. The coagulum is then washed, machined into cr<\>zepe and dried in the usual manner.  In another example latex is coagulated and machined to a thin tissue-like cr<\>zepe and in this form is drawn through a bath which contains 0.5 grm to 1 grm/litre of xylyl mercaptan, at such a rate that the cr<\>zepe remains in the bleaching bath for 2-10 secs. The cr<\>zepe is then rinsed and hung to dry.  Specification 531,723 is referred to.
