Abstract

A heat-insulating or sound insulating board is prepared by depositing upon the screen of a paper-making machine an aqueous slurry of expanded perlite particles and fibres together with an adhesive binder. The perlite particles may comprise about 40% to 80% by weight of the dry product, the fibres from 10% to 50% and the binder up to 30%. The product consists essentially of perlite particles in point contact and held together in a matrix of fibres lying in the voids between the perlite particles. Even distribution of the fibres is important and is more readily achieved with short fibres such as e.g. newsprint pulp, the binder being added to increase the cohesion of the fibres and thus the strength of the board. The board may be passed through a single pair of press rolls before final drying is effected by heat. Examples of suitable binders include: bituminous emulsions, sodium silicate, pitch, bentonite, synthetic resins, such as calcium acrylate and dispersions of starch and cements. Sodium silicate is particularly suitable as a binder where flame resistant properties are required in the product. Where starch is used as a binder the board is found to have water resistant properties which may be further increased the addition of an aqueous emulsion of vinyl acetate polymer. For heat insulation applications in which the temperature may lie between 600 DEG F. and 1200 DEG F. asbestos or glass fibres may form part or all of the fibre content of the board. The particle size of the perlite is such that the greater part of the particles will pass a 20 mesh screen and a substantial proportion is of about 100 mesh size.
