Patent GB-418757-A (GB)
Title: Improvements in or relating to the manufacture of goods of rubber or similar material
IPC: C08J9/00
Filed: 1933-05-18
Abstract: A method for the production of rubber goods from aqueous emulsions or dispersions comprises admixing the emulsions &c. with portions or fragments of one or more solidified aqueous gels or jellies of hydrophilic colloidal substances, permitting the emulsions &c. to solidify and coagulate, vulcanizing the solidified product under such conditions that evaporation of the liquid contained therein is prevented and subsequently removing the said substances.  Examples of these substances are gelatine, agar agar, starch, starch acetate, gum tragacanth, algin, Iceland moss, pectin, and silicic acid.  In an example a jelly formed by dissolving 60 gms. of gelatine in 1800 c.c. water and cooling is reduced to small pieces of the size of peas or grains of wheat by forcing several times through a mesh and quickly mixed with 175 c.c. water.  A vulcanizable latex mixture is then introduced and the whole rapidly stirred.  The resulting semi-fluid mass is poured into a seat mould, left overnight in a cool place and next day placed in hot water (204 DEG  F.) for 65 minutes whereby vulcanization occurs.  The seat is removed, washed in warm water to remove the gelatine, drained in a centrifuge and dried.  The jelly can be removed by squeezing.  The said substances may contain a mouldicide such as thymol and a small amount of coagulant for the rubber-e.g. to a 4 per cent solution of gelatine in water which will set on cooling is added 5 per cent of zinc sulphate calculated on the weight of the gelatine.  If the coagulant is only sparingly soluble-e.g. calcium sulphate or sodium silicofluoride-it may be introduced into the gel as a suspension or emulsion.  Other coagulants which may be employed with the hydrophilic substances are soluble salts of polyvalent metals-e.g. calcium, magnesium, zinc, aluminium.  Specifications 219,635 and 290,313, [both in Class 70], are referred to.  Reference has been directed by the Comptroller to Specification 414,234.
