Document Type and Number:
Japanese Patent JP2735201
Kind Code:
B2
Abstract:
A lightweight soundproofing, insulation and fireproofing material and method is disclosed. A dry composition is provided which includes 60-80% by weight of an inorganic lightweight nonflammable fibrous material, 16.67-36.67% by weight of an organic lightweight normally-flammable fibrous material, and 3.33-10% by weight of a refracted clay material. The non-flammable fibrous material is pulled apart to provide a high temperature loose fiber material, the normally-flammable fibrous material is shredded, and the refracted clay material is embedded in the normally-flammable fibrous material after shredding to reduce the flammability thereof. Thereafter, the nonflammable fibrous material is mixed with the normally-flammable fibrous material to complete the dry composition. A liquid adhesive is provided which includes liquid sodium silicate having a ratio of silicon dioxide to sodium oxide that is greater than 3.22:1, the liquid sodium silicate in the form of a solution of about 50% water is mixed with water in a ratio of approximately 1:1, and a surfactant can be added to the liquid sodium silicate to act as a wetting agent for application and flexibility purposes. With these constituent components, the liquid adhesive is used with the dry composition at the rate of approximately 55 gallons of liquid adhesive for each 300 lbs. of dry composition.
