Fire-resistant material, noncombustible material for treating interior building material and processes for their production

摘要

A fire-resistant material which is produced by mixing, in a predetermined ratio, agent A prepared by diluting a liquid mixture of calcium chloride and boric acid with water, agent B comprising silicone resin, sodium silicate, and polyvinyl acetate resin and agent C comprising ammonium monophosphate silica gel. A noncombustible material for treating interior building materials which is produced by mixing the above- described fire-resistant material with a mixture of powder D prepared by grinding and drying a mixture of an aqueous boric acid solution and an adhesive aqueous solution of paper powder, an earth/rock powder prepared by reducing and heating loess, sand, waste coal, and diatomite powder.PPThe noncombustible material can be sprayed over or appiled on combustible materials such as wood, textiles, paper, plastics, etc. to make them noncombustible and, upon starting of a fire, it foams to form an insulating layer which exhibits a sufficient heat-insulating effect and neutralizes and controls toxic gases.
