Abstract

1440309 Coated perlite BRITISH INDUSTRIAL SAND Ltd 23 May 1975 22490/75 Heading B2E Expanded perlite particles having a particle size from 0.1 mm. to 5.0 mm. are coated with 35 to 100 parts by weight of bitumen per 100 parts by weight of perlite by mixing or spraying the perlite particles with 70 to 200 parts by weight per 100 parts by weight of perlite, of an aqueous alkaline anionic bitumen emulsion as defined by British Standard 434 Bitumen Road Emulsions, and drying the coated particles at below 120‹C to obtain a free flowing composition of coated perlite. The bitumen is a petroleum bitumen having a grade range of between 70 and 200 penetration, suitably a bitumen complying with British Standard 3690-Bitumen for Road Purposes. The coated perlite particles may be compacted e.g. by rolling, to form a screed useful for roofing, having good thermal insulation properties.
