Definitions
- the present invention relates to polyol mixtures suitable for the production of rigid polyurethane foams which contain addition products of alkylene oxide to aromatic di- or polyamines, and to rigid foams produced using these polyol mixtures.
- Rigid foam polyether polyols usually have a viscosity of 2,000 to 15,000 mPas at 25 ° C, in exceptional cases basic polyols can also be found with viscosities of up to 40,000 mPas at 25 ° C. Polyols are usually used with
- a starter with active hydrogen atoms e.g. B. a polyalcohol such as sucrose or sorbitol or a primary or secondary polyamine, e.g. B. ethylenediamine or tolylene diamine, implemented with an alkyl oxide using a basic catalyst.
- amines in particular, the procedure is often such that one at a time
- Alkylene oxide per NH group is added to the amine.
- the addition of further alkylene oxide then takes place only after addition of basic catalyst, e.g. KOH. This complicates and slows down the entire process. This is particularly pronounced in the case of the technically interesting PO polyethers started on aromatic amines.
- Such polyethers have a very favorable influence on the thermal conductivities, strength, curing and blowing agent (alkane) solubility.
- Polyethers based on aromatic amines in which a maximum of one alkylene oxide, preferably predominantly propylene oxide (PO), is added per NH group can be prepared in a one-step process.
- a maximum of one alkylene oxide preferably predominantly propylene oxide (PO)
- PO propylene oxide
