A method for imparting flame resistance to exposed surfaces of wood by impregnating and reacting wood surfaces with dimethyl(oxiranylmethyl)phosphonate (DMOMP) is described. The resulting treated wood products are useful in applications where flame resistance is important.

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...

The present invention relates to flameproof textile articles and to processes for obtaining the same. The textile articles consist or consist essentially of halogen-containing modacrylic polymers containing on their surface about 0.2% to 2% by weight of silica relative to the weight of the articles. They are obtained by treatment with an emulsion of a hydrogenopolysiloxane compound in the presence of a curing catalyst, followed by a heat treatment at a temperature which can vary between about 10...

Disclosed is a dust-controlling mat comprising tufted pile yarns containing fibers composed of a grafting product or polymer blend of polyvinyl alcohol and polyvinyl chloride and a dust adsorbing agent retained in the tufted pile yarns in an amount of 1 to 40% by weight based on the tufted piled yarns. This dust-controlling mat has an excellent dust-controlling property and a highly improved flame-proofing property in combination.

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.

Wood products impregnated with from 30 to 80% of a polymerizable monomer selected from the group consisting of hexanediol diacrylate and hexanediol dimethacrylate have excellent indent resistance. The wood products are impregnated with the monomer solution by placing the wood under a vacuum to remove air, contacting the wood with a monomer solution containing a polymerizable hexanediol diacrylate and/or hexanediol dimethacrylate monomer and from 0.5 to about 2 percent of a thermally activated fr...

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 ...

A textile product with enhanced flame and/or smoke retardant properties and a method of forming the same is disclosed. The textile product is comprised of a textile material having a primary layer or backing with intumescent particles coated, sprayed, sprinkled, or otherwise applied to the upper surface thereof. Additionally or alternatively, the particles may be incorporated into the tufting primary or backing. The intumescent particles may also be complexed with additional agents, such as anti...
