Definitions
- the present invention relates to non-combustible polyester polyol and / or polyether polyol premixes for the production of foams, in particular polyurethane foam products.
- Polyurethane foams are produced by reacting isocyanates with a polyol or a polyol mixture in the presence of blowing agents, preferably hydrofluoric acids.
- 1, 1, 1, 3,3-pentafluorobutane (HFC 365mfc) as a blowing agent for the production of polyurethane foams is known. Since 1, 1,1, 3,3-pentafluorobutane has a flash point below -27 ° C, it is considered an easily flammable liquid and there are limits to its use as a blowing agent. Therefore, 1, 1, 1, 3,3-pentafluorobutane is usually used in a mixture with other fluorocarbons.
- blowing agent mixtures contain in addition to HFC 365mfc e.g. 1, 1, 1, 2-tetrafluoroethane (HFC 134a) or 1, 1, 1, 2,3,3,3-heptafluoropropane (HFC 227ea) or 1, 1,1, 3,3-pentafluoropropane (HFC 245fa). These blowing agent mixtures have no flash point and are suitable for the production of foamed plastics.
- WO 02/099006 describes a non-combustible composition of 1, 1, 1, 3,3-pentafluorobutane, 1,1, 1, 3,3-pentafluoropropane and 1, 2-dichloroethylene.
- WO 00/56833 describes ternary and quaternary mixtures which, in addition to 1, 1,1,3,3-pentafluorobutane, can also contain N-propyl bromide. It is also known and customary to first produce so-called premixes from the various starting materials for foam production, which are then reacted with the isocyanate. To prepare the premix, polyols or polyethers, blowing agents, catalysts and, if appropriate, further additives are mixed with one another in the required amounts. The foams are then produced by contacting the premix with the isocyanate or isocyanates.
- the object of the invention is to provide a non-combustible, stable premix for the production of foams which has no flash point.
- the non-combustible premix for the production of foam products from polyols preferably polyether polyol and / or polyester polyol, additives such as catalyst, stabilizer, additives and blowing agents or blowing agent mixture is characterized in that this premix contains halogenated alkanes.
- Premixes according to the invention preferably contain
- polyol preferably polyether polyols or polyester polyols are used;
- blowing agent mixture in addition to HFC-365mfc at least 5 wt .-%, preferably 7 to 50 wt .-% of another hydrofluorocarbon, preferably HFC 134a Contains HFC 227ea or HFC 245fa;
- halogenated alkanes preferably means substitution with chlorine or bromine.
- Compounds from group 1, 2-dichloroethane, 2-chloropropane, 1-bromopropane can be used as halogenated alkanes.
- phosphorus compounds as flame retardants is unnecessary - preferably no phosphorus compounds are used.
- known phosphorus-based flame retardants could also be used.
- additives such as e.g. Catalyst, stabilizer and other additives added.
- the premix according to the invention is brought into contact with the isocyanate or isocyanates and foamed in a known manner.
- Polyisocyanates for example with 2 to 4 isocyanate groups, are usually used to produce the polyurethane foams. Their manufacture and the basic chemicals that can be used for them are known.
- isocyanates have an aliphatic hydrocarbon residue with up to 18 carbon atoms, a cycloaliphatic hydrocarbon residue with up to 15 carbon atoms, an aromatic hydrocarbon residue with 6 to 15 carbon atoms or an araliphatic hydrocarbon residue with 8 to 15 carbon atoms on.
- Technically particularly preferred starting components are, for example, 2,4- and 2,6-tolylene diisocyanate, diphenylmethane diisocyanate, polymethylene polyphenyl isocyanate and mixtures thereof.
- So-called modified polyisocyanates can also be used, which contain carbodiimide groups, urethane groups, alophnate groups, isocyanorate groups, urea groups or urethral groups.
- Other starting components are compounds with at least 2 hydrogen atoms which are reactive toward isocyanates.
- they are compounds with a molecular weight of 300 to 10,000, which preferably have 2 to 8 hydroxyl groups and can also have amino groups, thio groups or carboxyl groups.
- Chemical blowing agents such as water can also be used as additional aids and additives in the system to be foamed.
- Catalysts such as, for example, tertiary amines, such as dimethylcyclohexylamine, and / or organic metals can also be used. metal compounds.
- Surface-active additives such as emulsifiers or foam stabilizers, for example siloxane-polyether copolymers, reaction retarders, cell regulators such as paraffins, fatty alcohols or dimethylpolysiloxanes, pigments and dyes can be used. Stabilizers against aging and weather influences, fillers, dyes, antistatic agents, nucleating agents, pore regulator substances or biocide-active substances can also be used.
- Suitable catalysts are mentioned, for example, in international patent application WO 96/14354. These include organic amines, amino alcohols and amino ethers such as morphoine compounds, for example dimethylcyclohexylamine, diethanolamine, 2-dimethylaminoethyl-3-dimethylaminopropyl ether, 2-dimethylaminoethyl ether, 2,2-dimorpholinodiethyl ether, N, N-dimethylaminoethylmorpholine, N-dimethylmorpholine.
- Organometallic compounds such as tin, cobalt or iron compounds are also useful as catalysts. For example, tin dioctate, cobalt naphthenate, dibutyltin dilaurate and iron acetone acetate can be used.
- the advantage of the premix according to the invention is that the addition behavior of halogenated alkanes obviously modifies the dissolving behavior of the components, so that the flash point increases and the "combustible" classification is omitted. This makes it easy to store and transport the premix.
