Title: Improved manufacture of aqueous dispersions of bituminous materials
IPC: C08L95/00
Filed: 1930-10-02
Abstract: Concentrated bituminous dispersions of low viscosity are prepared by forming a bituminous dispersion of normal characteristics, (particle size about 2 m ), and dispersing therein a further quantity of the same or other bituminous material, the particles of the second dispersion being of the order 20-30 m .  The two steps of the process may be carried out in a colloid mill and in a mixer respectively, or wholly in a mixer in which case the additional bitumen is supplied at an increased rate or with slower mixing or with both such measures. In an example 57 parts of Venezuelan " Spramex " are emulsified in 43 parts of 1,5 per cent potassium oleate solution in colloid mill, the dispersion is transferred to a helical-screw paddle mixer and molten " Spramex " added until the total bitumen content is 85 per cent.
