    摘要: The invention disclosed is a fire resistant inorganic coating composition which intumesces when subject to high temperatures to form a substantially continuous heat insulating structure and retains this structure for prolonged periods at temperatures up to 1000.degree. C. The coating composition comprises______________________________________ Parts by Weight ______________________________________ sodium silicate (aqueous solution) 40-70 potassium silicate (aqueous solution) 40-70 silicon carbide powder 3-15 ______________________________________ A composite fire-protective coating system is also disclosed which comprises a plurality of coatings sequentially applied to the substrate, typically aluminum, to be protected. Specifically, a first heat resistant, substantially air impermeable bonding layer and an inorganic intumescent layer as described above. An additional heat resistant air impermeable layer may be included as a top coat. Some applications may require an additional inorganic intumescent layer.

    摘要: An intumescent powder where the molar ratio of SiO2 to Li2O+Na2O+K2O is between 2.20 to 3.70 to 1.00 and the molar ratio of Li2O to Li2O+Na2O+K2O is 0.20 to 0.35 has an intumescent point of 195° C. or higher and thus will not prematurely intumesce if mixed with another material at temperatures below 195° C. The powder as used is usually dried to 8-12% by weight to moisture for most purposes is ground to 50 to −500 microns. Preferred methods of manufacture comprise taking a source of lithium hydroxide or lithium silicate and a source of sodium silicate to create a powder with ratios as outlined above.

    摘要: A compound is provided having the means of intumescence at temperatures above 195° C. to 220° C. The compound is an intumescent powder defined by the molar ratios (2.20 to 3.70) SiO2/(0.20 to 0.35) Li2O: (0.65 to 0.80)(Na2O+K2O) where the coefficients of Li2O and of (Na2O+K2O) total 1.00 and thermoplastic material having a plastic state at less than 195° C. If the thermoplastic contains a halogen, as does Polyvinyl Chloride (PVC) the halogen acts as a flame retardant in the event of combustion and prevents complete burning of the plastic. If there is as filler mixed with the compound which is endothermic this assists with the fire retardant effect of the compound.
