Definitions
- the invention relates to novel methods for controlling (prolonging) the pot life in chain-extended polyurethane (PU) -based systems with diamines, preferably PU elastomers, PU adhesives and PU casting resins.
- PU polyurethane
- Polyurethanes are formed by polyaddition reaction of polyisocyanates with polyhydric alcohols, the polyols, almost quantitatively.
- the course of the reaction between diisocyanate and polyol depends on the molar ratio of the components. Intermediates with the desired average molecular weight and desired end groups can be obtained. These intermediates can then be reacted (chain-extended) with a diol or diamine at a later time to form the desired polyurethane or polyurethane-polyurea hybrid.
- the intermediates are generally referred to as prepolymers.
- Suitable polyols for the preparation of prepolymers are, in addition to the diols, also polyalkylene glycol ethers, polyether esters or polyesters having terminal hydroxyl groups (polyester polyols).
- polyester polyols are preferably used.
- polyether esters or polyesters having terminal hydroxyl groups prepared by polycondensation of simple diols and carboxylic acids still contain free carboxylic acids. These catalyze the reaction between the free isocyanate groups contained in the prepolymer and the diamine required for the chain extension, which leads to short pot lives and makes the reaction uncontrollable. In addition, these often have a low hydrolytic stability.
- the object of the present invention was therefore to provide processes for controlling (prolonging) the pot life in diamine-chain-extended polyurethane (PU) -based systems, in particular for the production of PU elastomers, PU adhesives or PU casting resins, without materials are needed, which are expensive and difficult to produce.
- the pot life in the sense of the invention is the processing time of reactive materials. It is the time between mixing a multicomponent substance and the end of its processability.
