Abstract
The present invention relates to the field of chemical compositions and flame retardants. Specifically, the invention relates to a composition for imparting flame retardancy comprising an organic salt as a fire-retardant compound, a binder and a surfactant. Also, the present invention relates to a method for manufacturing said composition and a method of imparting flame retardancy to a substrate comprising applying said composition to the substrate. And still, the invention relates to uses of said composition e.g. for imparting flame retardancy to a substrate. Furthermore, the invention relates to products comprising said composition.
Claims17
A composition for imparting flame retardancy, wherein the composition comprises:
- an organic salt as a fire-retardant compound,
- a surfactant, and
- a binder,
- wherein the composition is free of ammonium phosphate and boron compounds,
- wherein the organic salt can be admixed with the binder without flocculation, creaming or sedimentation,
- wherein the organic salt is selected from the group consisting of potassium, magnesium, or bismuth salts of an organic acid, and any combination thereof,
- wherein the organic acid is selected from the group consisting of citric acid (CAS number 77-92-9) and its hydrates, and any combination thereof,
- wherein the binder comprises at least one member selected from the group consisting of:
- a polymer of one or more acrylate monomers independently selected from the group consisting of n-butyl acrylate (BA), methyl methacrylate (MMA), lauryl acrylate, and phenoxy ethyl acrylate;
- a copolymer of two or more monomers, each independently selected from the group consisting of acrylates and styrene;
- copolymers formed from monomer mixtures comprising BA and MMA together with functional monomers comprising silicon, phosphorus, fluorine, nitrogen derivatives and/or radical generators, or combinations thereof;
- and
- a polymer of an acrylate or styrene, wherein the acrylate is selected from the group consisting of n-butyl acrylate (BA), ethyl acrylate, methacrylates, lauryl acrylate, phenoxy ethyl acrylate, tripropylene glycol diacrylate, hexanediol diacrylate, and trimethylolpropane triacrylate,
- wherein the composition comprises 10-70% of the organic salt by weight of the composition, and
- wherein the composition is in the form of an aqueous solution.
