A flame-proof and no-smoke-producing wooden plate for architectural use comprising a wooden base plate, a layer of a water-proof composition formed on said wooden plate, a layer of a water-soluble silicate selected from the group consisting of sodium silicate or potassium silicate formed on said layer of said water-proof composition, and an additional layer of a water-proof composition formed on said water-soluble silicate layer. Each of said water-proof compositions is formed by adding to a wat...

An internal combustion engine and a method of coating a combustion chamber wall surface therein comprising the steps of preheating the base metal forming the wall surface to at least 500.degree. F. and fusion bonding a base layer of nickel and aluminum to the preheated base metal for retarding conductive heat transfer through the wall surface. An intermediate layer comprising nickel, aluminum, and copper is applied over the base layer and an outer layer of copper for reflecting infrared heat is ...

A method comprising the step of melt processing stabilized composition comprising a copolymer comprising from 70 to 95, and preferably 75 to 90 percent by weight of vinyl chloride and from 5 to 30 and preferably 10 to 25 percent by weight of chlorotrifuloroethylene and an effective amount of a stabilizer. The step of melt processing includes extruder processing or roll mill processing. A preferred melt processing step is melt coating the copolymer onto a substrate such as a wire. The present inv...

This invention relates to a fire barrier material comprising at least about 25 weight % binder; at least about 10 weight % intumescent compound; and at least about 5 weight % organic fibers comprising an organic material having pendant hydroxyl groups, wherein the density of the fire barrier material ranges from greater than zero to about 0.35 grams/cm.sup.3 as well as a method of making the fire barrier material.

A reinforcement system for mastic intumescent fire protection coatings. Free floating carbon mesh embedded in the coating is used to reinforce the coating. Optionally, the carbon mesh may be used in conjunction with mechanically attached reinforcements.

A fire-retardant coating material including a fluid intumescent base material having a foaming agent, a blowing agent, a charring agent, a binding agent, a solvent, and a pigment. The coating material further includes a flame spread reduction agent; refractor fibers dispersed in the fluid intumescent base material; an oxidation reduction agent; a thermal transmission reduction agent; a stabilizer and volatile organic reduction component; a mechanical enhancer component for physical impact resist...

A non-woven fiber mat for use as a backing material for various components used in the building industry, and having improved fire resistant qualities. The mat comprises a blend of mineral fibers and glass fibers bonded together with a fire resistant binder system. The binder system comprises a mixture of a fire resistant latex and an aqueous aldehyde condensation polymer-based thermosetting resin. The preferred weight ratio of the latex to the aldehyde condensation polymer is at least 1:1 on a ...

This invention consists of a flame-retardant, coated fabric material for use in the manufacture of rolling-door panels, blades, or leaves. It is particularly designed for use in the kind of high-speed, light-weight doors currently found in the garages and vehicle bays of warehouses, factories, and other industrial facilities. In addition to being much lighter than the metal doors being replaced, the material of the present invention has to its further advantage a flame-retardancy not present in ...

A heat-insulating material comprising from 85 to 98 parts by weight of mineral wool and from 15 to 2 parts by weight of a binder applied onto the wool, which is a modified resol phenol-formaldehyde resin on the basis of phenol, formaldehyde, sodium hydroxide, a water proofing additive which is an individual alkylresorcinol with a number of side chain carbons of 2 to 8 or a mixture of alkylresorcinols, as well as urea, or dicyandiamide, or melamine, the ratio between said components being as foll...

A device for containing and extinguishing fires and for preventing fires comprises a double-layer plastics foil consisting of polyethylene or polyproplene which contains flame-smothering or flame inhibiting additives, the foil being intended in use to be laid upon burning or endangered objects to form an air-excluding protective layer which covers all irregularities in sealed manner due to the pliability of the foil. The double-layer foil is produced by blowing on an extruder, flame-smothering o...
