| titleOfInvention | Improvements in or relating to the manufacture of goods of or containing rubber or similar material |
| abstract | Articles of microporous rubber and the like which are free from surface markings and easily removable from the mould are made by a modification of the known process in which dispersions are gelled and vulcanized under such conditions that evaporation of the liquid contained in the pores is prevented, characterized in that the mould surfaces are treated before the introduction of the dispersions with certain non-oily metallic soaps of the higher fatty acids. The soaps promote gelling of the latex in contact with the mould surface and cause even distribution of the gas which collects between the metal plate and the surface of the latex. The soaps are those of zinc, cadmium, magnesium, aluminium and ferric iron, and the preferred example is zinc stearate. The salts are applied by spraying in an aqueous, or preferably in a methylated spirit dispersion. The latter has the advantage that a dispersion is easily obtained, has good wetting qualities, and easily evaporates, leaving a film of lubricant on the mould surface, which may be warmed to assist evaporation. The invention is particularly applicable to the processes described in Specifications 346,810, 351,937, 366, 120,377, 751, and 393,022. Specifications 219,635 and 290,313, [both in Class 70, Indiarubber &c.], also are referred to. |
