DIRECT PRODUCTION OF RUBBER GOODS FROM RUBBER DISPERSIONS.
1T0 Drawing. Application filed September 14, 1927, Serial No. 219,555, and in Greta Britain August 4, 1926.
This invention relates to the manufacture ess we may add 6 to 12 grams of soft soap to of rubber goods from rubber dispersions.
Processes have been proposed based on the fact that it-ais possible to deposit rubber on a deposition stratum by electrical means and o tain deposits of diflerent even considerable thicknesses without having the risk of totally cutting ofi the electric current by insulation, which would prevent further deposition.
One of the main features of these processes is to get the right degree to coagulation in the' deposit thus obtained. The deposit must be nical requirements such as adhesion to the coagulated to a certain extent to fulfil tech- 15 mould when the latter is removed from the bath, and the like. On the other hand a too strong coagulation of the depositincreases the electrical resistance in an undesirable manner. obviate these disadvantages. We have now found that an addition of certain protective substances or peptising agents furnish a good means of regulating the degree of coagulation.
According to this invention we add to the rubber disperson a peptizing agent such as a protective colloid (for example. soft soap) or an alkali, and carry out the process described and claimed in any of the said specifications. This has the eflectof producing a much tougher deposit than is obtainable without such prior addition without increasing the electrical resistance in an undesirable manner as aforesaid. T As an example of the above described proc- The object of this invention is to 1 litre of latex containing about 30% of rubber, which may or may not be preserved by ammonia or by any other preserving agent,
and then depositing out of this dispersion, 4o
- for example on a porous mould, using a current density of 3 amperes per square decimetre of mould surface during a time of 5 minutes to produce a deposit of approximately 2 millimetres in thickness. The current density or time may be varied according to the, thickness of deposit required.
Without departing from the scope thereof the present invention is applicable not only to unvulcanized or vulcanized natural or artificial rubber emulsions with or without additional substances and conditioning agents,, but also to natural or artificial, vulcanized or unvulcanized, emulsions of other rubber like substances, as for example gutta-percha or balata. with or without additional substances and conditioning agents.
. What we claim is:
In the manufacture of rubber' and the like or articles manufactured therefrom the process which comprises regulating the degree of coagulation by adding soft soap to natural latex in the proportion of 6 to 12 grams of soft soap tol litre of 18K and depositing the latex by electrophoresis upon an anodic mould.
In witness whereof, we have hereunto signed our names.
