Definitions
- the present invention relates to a flame-retardant, consisting of one or more ct-olefin-vinyl acetate copolymers having a vinyl acetate content of 40 to 90 wt .-%, based on the total weight of the ⁇ -olefin-vinyl acetate copolymer polymer composition, their use and a flame retardant combination for upgrading plastics and rubbers.
- Flame-retardant polymer compositions are used, for example, in cable applications (cable sheath and cable insulation) and floor coverings. Such polymer compositions should have a sufficient flame retardant according to the legal standards and also excellent processing properties.
- inorganic flame retardants halogenated flame retardants, organophosphorus flame retardants or nitrogen-based flame retardants.
- mineral flame retardants are metal hydroxides, in particular aluminum hydroxides (ATH) and magnesium hydroxides (MDH) mentioned, which are used in polymers as flame retardant fillers.
- Metal hydroxides are used alone or in combination with each other and optionally in combination with other flame retardant additives.
- the flame retardancy is based essentially on an endothermic decomposition of the crystals, the release of water in the form of water vapor with simultaneous dilution of the concentration of combustible gases in the vicinity of the attacked plastic and the formation of a more or less solid oxide residue.
- the oxide residue itself has a high inner surface and can thus adsorb soot particles or precursors of the soot (polycyclic aromatic hydrocarbons, PAHs).
- This so-called ash layer acts as mechanical stabilization of the burning polymer, so that, for example, burning dripping of the polymer is reduced or completely avoided.
- the encrusted ash layer on the surface of the burning polymer acts as a kind of "protective barrier" for the underlying polymer layers, whereby a rapid further burning can be avoided.
- salts of phosphinic acids have proven to be effective flame retardant additives for polymer systems.
- Calcium and aluminum phosphinates have been described as particularly effective in polyesters or polyamides and affect the material properties of the polymer compositions less than z.
- synergistic combinations of phosphinates with certain nitrogen-containing compounds have been found to be more effective as flame retardants in many polymers than the phosphinates alone.
- melamine and melamine compounds are known to be effective synergists, such as meiaminocyanurates and melamine phosphate.
- the present invention proposes a flame-retardant polymer composition of the type mentioned, which consists of one or more ⁇ -olefin-vinyl acetate copolymers having a vinyl acetate content of 40 to 90 wt .-%, based on the total weight of ⁇ -Olefm- Vinyl acetate C op polymers and consists of a synergistic flame retardant combination containing as component A a phosphinic acid salt of the formula (I).
- Component A is also referred to herein as phosphinates.
- LOI Limiting Oxygen Index
- TTI Time to Ignition
- UL 94 Another method of assessing and classifying the flammability of plastics is UL 94.
- the UL94 classification is performed on 3.2 mm thick samples. According to the UL 94-V standard, classification is in unclassified (NC), V2 (better), VI (even better), V0 (maximum grading).
- component A is an aluminum phosphinate.
- the melamine compound is preferably melamine phosphate, melamine borate and / or melamine cyanurate.
- the total amount of synergistic flame retardant combination of the polymer composition according to the invention is preferably between 90 and 310 phr, more preferably between 100 and 190 phr.
- the polymer composition according to the invention preferably has 70 to 190 phr of component B, 10 to 60 phr of component A and 10 to 60 phr of component C.
- the polymer composition according to the invention particularly preferably comprises 80 to 160 phr of ATH, 10 to 30 phr of aluminum phoshinate and 10 to 20 phr of melamine phosphate or melamine borate.
- the ⁇ -olefin-vinyl acetate copolymers used are characterized by high vinyl acetate contents of> 40 wt .-%, based on the total weight of the ⁇ -olefin-vinyl acetate copolymer.
- the vinyl acetate content of the ⁇ -olefin-vinyl acetate copolymers used according to the invention is preferably from 50% by weight to 80% by weight, based on the total weight of the ⁇ -olefin-vinyl acetate copolymers.
- the ⁇ -olefin-vinyl acetate copolymer used may have, in addition to the ⁇ -olefin and vinyl acetate based monomer units, one or more other comonomer units (e.g., terpolymers), e.g. based on vinyl esters and / or (meth) acrylates.
