Definitions
- EPS expandable styrene polymer
- the invention relates to flame-retardant, expandable styrene polymer (EPS) granules containing as flame retardants an organic bromine compound having a bromine content of at least 70 wt .-% and a Flammtiksynergisten, wherein at least a portion of the Flammtiksynergisten is in the form of a coating, and to processes for their preparation and use for self-extinguishing styrene polymer particulate foams.
- EPS expandable styrene polymer
- EPS expandable styrene polymer
- DE-A 42 40 109 describes finely divided, expandable styrene polymers which contain flame retardants and flame retardant synergist both in a homogeneous distribution in the styrene polymer and as a surface coating.
- the prefoamed particles can be welded to self-extinguishing foam blocks by further treatment with steam with non-flame retarded polystyrene foam recyclate.
- the object of the invention is therefore to remedy the disadvantages mentioned and to find flame-retardant, expandable styrene polymers with sufficient flame retardancy, which can be produced reproducibly with lower amounts of flame retardant synergists.
- the flame-retardant, expandable styrene polymers (EPS) granules according to the invention preferably comprise (EPS) granules a) 0.1 to 5 wt .-%, in particular 0.3 to 2 wt .-% of the organic bromine compound and b) 0.01 to 1, 0 wt .-%, in particular 0.1 to 0.5 wt. -% of a flame retardant synergist.
- the coating preferably contains no organic bromine compound and the flame retardant synergist is present in the coating at from 40 to 100% by weight, in particular from 70 to 95% by weight.
- styrene polymers to glassy polystyrene (GPPS), toughened polystyrene (HIPS), anionically polymerized polystyrene or toughened polystyrene (A-IPS), styrene- ⁇ -methstyrene copolymers, acrylonitrile-butadiene-styrene polymers (ABS), styrene-acrylonitrile (SAN ) Acrylonitrile-styrene-acrylic esters (ASA), methyl acrylate-butadiene-styrene (MBS), methyl methacrylate-acrylonitrile-butadiene-styrene (MABS) - polymers or mixtures thereof or with polyphenylene ether (PPE) used.
- GPPS glassy polystyrene
- HIPS toughened polystyrene
- A-IPS anionically polymerized polystyrene or toughened polystyren
- the expandable styrenic polymer has a molecular weight in the range of 190,000 to 400,000 g / mol, more preferably in the range of 220,000 to
- the expandable styrene polymer (EPS) granules generally contain one or more blowing agents in a homogeneous distribution in a proportion of 2 to 10 wt .-%, preferably 3 to 7 wt .-%, based on the EPS granules.
- Suitable blowing agents are the physical blowing agents commonly used in EPS, such as aliphatic hydrocarbons having 2 to 7 carbon atoms, alcohols, ketones, ethers or halogenated hydrocarbons. Preference is given to using isobutane, n-butane, isopentane, n-pentane.
- the flame retardants used are organic bromine compounds having a bromine content of at least 70% by weight.
- Particularly suitable are aliphatic, cycloaliphatic and aromatic bromine compounds, such as hexacyclododecane, pentabrammonochlocyclohexane, pentabromophenyl allyl ether.
- Suitable flame retardant synergists are thermal free-radical formers having half-lives of 6 minutes at temperatures ranging from 110 to 300 ° C, preferably 140 to 230 0 C.
- the EPS granulate contains hexabromocyclododecane (HBCD) as flame retardant and dicumyl or dicumyl peroxide as flame retardant synergist.
- HBCD hexabromocyclododecane
- dicumyl or dicumyl peroxide flame retardant synergist.
- the weight ratio of flame retardant synergist to organic bromine compound is usually in the range of 1 to 20, preferably in the range of 2 to 5.
- the flame-retardant, expandable styrene polymer (EPS) granules according to the invention can be prepared by melt impregnation of styrene polymers and subsequent underwater granulation or suspension polymerization of styrenic monomers.
- EPS expandable styrene polymer
- at least a part of the flame retardant or the flame retardant components is incorporated into the styrene polymer melt or polymerized styrene monomers in their presence and then coated the resulting EPS granules with the rest of the flame retardants or flame retardant components.
- EPS expandable styrene polymers
- the residence time of the flame retardant and the flame retardant synergist can be maintained at a melt temperature in the range of 140 to 220 ° C, preferably in the range of 170 to 200 ° C at less than 15 minutes
- additives, nucleating agents, fillers, plasticizers, soluble and insoluble inorganic and / or organic dyes and pigments may be added to the styrene polymer melt together or spatially separated, eg via mixers or side extruders.
- the dyes and pigments are added in amounts ranging from 0.01 to 30, preferably in the range of 1 to 5 wt .-%.
- a dispersing assistant for example organosilanes, polymers containing epoxy groups or maleic anhydride-grafted styrene polymers.
- Preferred plasticizers are mineral oils, phthalates, which can be used in amounts of 0.05 to 10 wt .-%, based on the styrene polymer.
- the finished expandable styrene polymer granules can additionally be coated by glycerol esters, antistatic agents or anticaking agents.
- the EPS granules may contain glycerol monostearate GMS (typically 0.25%), glycerol tristearate (typically 0.25%) finely divided silica Aerosil R972 (typically 0.12%) and Zn stearate (typically 0.15%), and antistatic be coated.
- GMS typically 0.25%
- glycerol tristearate typically 0.25%
- finely divided silica Aerosil R972 typically 0.12%
- Zn stearate typically 0.15%
- the flame-retardant expandable styrene polymer granules according to the invention can be prefoamed in a first step by means of hot air or steam to give foam particles having a density in the range from 8 to 100 g / l and, in a second step, sealed in a closed mold to form self-extinguishing particle moldings.
- PS polystyrene melt
- VZ viscosity number
- the mixture of polystyrene melt, blowing agent and flame retardant was conveyed at 60 kg / h through a nozzle plate with 32 holes (diameter of the nozzle 0.75 mm). With the help of pressurized underwater granulation, compact granules with a narrow size distribution were produced.
