Definitions
- phosphorus-containing flame retardants in the production of plastics based on isocyanate, preferably polyurethane plastics including hard and calibration foams, has long been known in the art.
- flame retardants are, for example, trischloroisopropyl phosphate (TCPP) or diphenyl cresyl phosphate (DKP).
- Halogen-free phosphate esters such as DKP are often inadequate in their flame retardancy and have to be dosed high, including the mechanical properties of the foams, e.g. the compression hardness suffers.
- TCPP has a good flame retardant effect, but migrates easily from the open-cell soft foams due to its high vapor pressure. As a result, it is not possible to use the TCPP in applications with low fogging requirements, for example in the automotive sector.
- a liquid flame retardant with a good effect is advantageous, which has a low tendency to migrate, in particular from the open-celled polyurethane flexible foams.
- n stands for a numerical value between 0.9 and 2
- R represents an optionally substituted alkylene radical, preferably isopropylidene or ethylene
- Preferred compounds of formula (I) are those in which
- Ar represents an optionally substituted C 1 -C 4 -arylene radical, for example
- n stands for a numerical value between 0.9 and 2.
- R for an optionally substituted unbranched or branched
- Ci-Cg-alkylene is such as methylene. Ethylene -CH 2 -CH 2 -.
- Shark represents halogen, preferably chlorine or bromine.
- Particularly preferred tetrakis-haloalkyl-arylene diphosphate esters are compounds of the general formula (I)
- n stands for a numerical value between 0.9 and 2
- R for propane-1, 3-diyl or iso-propylidene stands and
- Particularly preferred bridged and halogenated aryl phosphate esters according to the present invention are the tetrakis chloropropyl ester of 1,3-phenylene diphosphate (TC-RDP) and the tetrakis chloropropyl ester of bisphenol A diphosphate (TC-BDP), which are used in the Implementation of the corresponding tetrachlorophosphoric diester can be obtained with propylene oxide, resulting in a mixture of tetrakis chloroisopropyl esters and tetrakis chloro-n-propyl esters with a higher proportion of tetrakis chloroisopropyl esters.
- T-RDP 1,3-phenylene diphosphate
- TC-BDP bisphenol A diphosphate
- Tetrakis chloroisopropyl 1,3 phenylene diphosphate Tetrakis-haloalkyl-arylene-diphosphate esters have already been used for other purposes.
- DE-A 2 122 773 describes, among other things, the use of tetrakis-chloroisopropyl-1,3-phenylene diphosphate as an adhesion promoter in composite rubber articles.
- Production processes for the compounds of the general formula (I) to be used according to the invention are also known in principle. They can be obtained analogously to the preparation of the trischloroisopropylene phosphate by reacting the corresponding tetrachlorophosphoric diester with propylene oxide in the presence of catalysts. A description of the manufacturing process can be found, for example, in Chapter 1.9 of the IUCLID (International Chemical Information Database). Due to the manufacturing process, oligomeric fractions corresponding to n> 1 are unavoidable.
- the compounds of general formula (I) to be used according to the invention are preferably used in amounts of 1 to 20% by weight, based on the plastic, preferably isocyanate-based plastics.
- the plastics based on isocyanate are predominantly plastics containing urethane and / or isocyanurate and / or allophanate and / or uretdione and / or urea and / or carbodiimide groups.
- the compounds of the general formula (I) to be used according to the invention are preferably used in the production of polyurethane, soft and rigid foams.
- isocyanate-based plastics A.
- starting components ahphatic, cycloaliphatic, araliphatic, aromatic and heterocychic polyisocyanates, as are described, for example, in DE-A 44 18 307, for example those of the general formula (II)
- n represents an integer from 2 to 4, preferably from 2 to 3, and
- Q for an aliphatic hydrocarbon residue with 2 to 18 C atoms, preferably with 6 to 10 C atoms, or for a cycloaliphatic hydrocarbon residue with 4 to 15 C atoms, preferably 5 to 10 C atoms, or for an aromatic hydrocarbon residue with 6 to 15 carbon atoms, preferably 6 to 13 carbon atoms or an araliphatic hydrocarbon radical with 8 to 15 carbon atoms, preferably 8 to 13 carbon atoms.
- polyisocyanates are used as are described in DE-A 28 32 253, pages 10 to 11.
- polyisocyanates for example the 2,4- and 2,6-tolylene diisocyanate (TDI), and any mixtures of these isomers (“TDI”), polyphenylpolymethylene polyisocyanates (“MDI”) are generally used with particular preference. as they are produced by aniline-formaldehyde condensation and subsequent phosgenation.
- TDI 2,4- and 2,6-tolylene diisocyanate
- MDI polyphenylpolymethylene polyisocyanates
- modified polyisocyanates polyisocyanates
- modified polyisocyanates in particular those modified polyisocyanates which differ from 2,4- and / or 2,6- Toluene diisocyanate or derived from 4,4'- and / or 2,4'-diphenylmethane diisocyanate can be used.
- Starting components are also compounds having at least two isocyanate-reactive hydrogen atoms with a molecular weight of generally from 400 to 10,000.
- thio groups or compounds having carboxyl groups this is understood to mean compounds having hydroxyl groups, in particular 2 to 8 hydroxyl groups
- compounds with at least two isocyanate-reactive hydrogen atoms and a molecular weight of 32 to 399 can be used as additional starting components.
- These compounds generally have 2 to 8, preferably 2 to 4, hydrogen atoms which are reactive toward isocyanates. Examples of this are described in DE-A 28 32 253, pages 19 to 20.
- auxiliaries and additives are used as well a) water and / or volatile organic substances such as pentane or cyclopentane as blowing agents,
- reaction retarders for example acidic substances such as hydrochloric acid or organic acid halides, further cell regulators of the known type such as paraffins or fatty alcohols or dimethylpolysiloxanes as well as pigments or dyes and other flame retardants of the known type, for example tricresyl phosphate, diphenylcresyl phosphate, melamine, ammonium polyphosphate, red phosphorus,
- Plasticizers and fungistatic and bacteriostatic substances as well as fillers such as barium sulfate, diatomaceous earth, soot or sludge chalk.
- isocyanate-based plastics is known.
- the reaction components are reacted according to the known one-step process, the prepolymer process or the semi-prepolymer process, machine equipment often being used, for example those described in US Pat. No. 2,764,565.
- foams can also be produced by block foaming or by the known foam molding process.
- the tetrakis-haloalkyl-arylene-diphosphate esters can generally be used in plastics to reduce flammability. They are preferably used in polyurethane plastics or in polyurethane foams. The tetrakis haloalkyl arylene disphosphate esters are therefore particularly suitable for use as upholstery material in the automotive and residential sectors. Rigid foams with the products to be used according to the invention can also be used, for example, as insulation and insulation material in the construction sector.
- the present invention therefore also relates to flame retardants which, in addition to other flame retardants, contain an effective proportion of tetrakis-halogenoalkyl-arylene-diphosphate esters in plastics and significantly reduce their flammability.
- Flexible polyurethane foams were produced according to the formulations described below both with the tetrakis-halogeno-alkyl-arylene-phosphate esters of the general formula (I) to be used according to the invention, such as the known trischloroisopropyl phosphate, and compared them in terms of fire behavior and migration rate :
