Definitions

  • the foamed ceramic material may advantageously be prepared by a known method which includes: (a) preparing a foam from a slurry of a particulate ceramic forming aluminosilicate material, eg a clay;
  • the portions may be divided by a divider or by allowing extrudate to fall onto a moving belt which by the action of carrying away the portions causes lengths or portions to break from the extruding material.
  • the granules, eg pellets or prills, so formed may be collected and optionally sized by one or more screen meshes, eg so that only lengths greater than a chosen minimum length, eg a minimum in the range 1mm to 5mm, are selected.
  • the granules are preferably dried to a water content of not more than 0.5% by weight. Drying may be carried out in a heated atmosphere, eg an oven, at a temperature of from 50°C to 200°C.
  • coated ceramic foam granules in host compositions to be formed into polymer composites also improves dispersion of the granules in the host composition, eg thermosetting or cold setting resin composition .
  • Filler A (Comparative) A low density filler prepared by the process described in GB-A-2271987 and consisting predominantly of particles of size in the range of from 3mm to 5mm.

Abstract

L'invention se rapporte à une matière expansée céramique comportant un revêtement en polymère de latex. Cette matière expansée céramique peut comporter un matériau granulaire fritté que l'on obtient en calcinant des granulés d'argile expansée et éventuellement en broyant finement ledit matériau granulaire fritté.
