Abstract
The present invention provides for a method of concentrating synthetic rubber latices, in particular all emulsion polymerised diene rubbers latices such as styrene-butadiene rubber (SBR) latex, neoprene latex, etc. The technique generally entails, firstly, adding creaming agents, such as tamarind seed powder or alginate (including ammonium alginate) to the synthetic rubber latex so that clustering of the latex particles may be achieved. The clustered latex particles are thus larger and is thus able to be centrifuged in the usual manner using conventional centrifuges or techniques to separate the concentrate from the skim.
Claims9
A process of concentrating emulsion polymerised synthetic rubber lattices comprising effecting clustering of the latex particles prior to centrifugation using commercially available centrifuges.
A process according to any one of the preceding claims further comprising mechanical centrifugation using commercial centrifuge means for producing synthetic rubber latex concentrates.
