Abstract
A liquid polymerizable material which may be used, for instance, for the coating of wood or other substrate, which material, when cured, is fire-resistant and protects the substrate. The material cures without application of heat and is formed from methyl methacrylate monomer, a hydroxy alkylacrylate or diacetone acrylamide monomer, a chlorinated hydrocarbon, an antimony compound, a zinc compound, a filler, and a catalyst-promoter system.
Claims13
A fire-resistant product comprising a flammable substrate and a layer of fire-retardant material bonded to the surface of the substrate, said material resulting from polymerization of a mixture comprising from 4-50 wt.% of a first monomer chosen from the group consisting of hydroxy ethylacrylate, hydroxy propylacrylate, hydroxy butylacrylate, ethylene glycol monoethyl ether acrylate and diacetone acrylamide, from 0-50 wt.% of an alkyl methacrylate monomer, and from 30-70 wt.% of a chlorinated paraffin containing from 40-75 wt.% chlorine and including a heat intumescents substance.
A fire-resistant product, comprising
- a. a substrate having high strength characteristics, and
- b. a protective layer bonded to the surface of the substrate, the layer being comprised of
- i. a first monomer chosen from the group consisting of hydroxy ethylacrylate, hydroxy propylacrylate, hydroxy butylacrylate, ethylene glycol monoethyl ether acrylate, diacetone acrylamide, and combinations thereof,
- ii. a chlorinated paraffin containing 40-75 wt.% of chlorine,
- iii. a hydrated mineral filler,
- iv. an inorganic flame retardant, and
- v. a catalyst-promoter system to cure the mixture.
