Definitions
- the present invention relates to materials with increased flexural modulus of polyurea compositions.
- Polyurethane or polyurea based two-component coating systems are known and used in the art. In general, they contain a liquid polyisocyanate component and a liquid isocyanate-reactive component. Reaction of polyisocyanates with amines as the isocyanate-reactive component gives rise to polyurea coatings. However, amines and isocyanates usually react very quickly with each other. Typical pot or gel times are often only a few seconds. Therefore, such polyurea coatings can not be applied manually, but only with special spray equipment.
- Coatings of polyureas are of particular interest because the reaction of polyisocyanates with amines proceeds extremely fast and the coated surfaces can be (re) used very quickly.
- the presence of urea groups in polyurethanes results in a very favorable ratio of hardness to elasticity, which is evident in many coating applications, e.g. the coating of pipes is very desirable.
- certain aromatic diamines whose reaction with isocyanates to form corresponding Polyharnstoffsystemen runs relatively slow, which improves the workability and the material properties.
- US Pat. No. 3,428,610 and US Pat. No. 4,463,126 disclose the preparation of polyurethane / polyurea elastomers by curing NCO-functional prepolymers with aromatic diamines. These are preferably di-primary aromatic diamines which, in the ortho position to each amino group, have at least one alkyl substituent having 2-3 carbon atoms and optionally also in further ortho positions to the amino groups methyl substituents, such as, for example, diethyltoluyldiamine (DETDA) , an isomeric mixture of the isomeric forms 2,6-diamino-3,5-diethyltoluene and 2,4-diamino-3,5-diethyltoluene.
- DETDA diethyltoluyldiamine
- Polyureas can also be used for coatings in contact with drinking water, as described for example in EP-A 0 936 235.
- Such coatings are obtained by mixing a liquid aliphatic polyisocyanate, which may additionally contain a liquid epoxy resin, with a liquid aromatic polyamine.
- aromatic raw materials For coatings in direct contact with drinking water, the use of aromatic raw materials is often considered disadvantageous.
- aromatic isocyanates could release aromatic amines under certain conditions.
- aromatic amines for the same reason, the use of aromatic amines as chain extenders is often viewed critically, because aromatic amines are classified as unwanted by the relevant regulatory authorities, which is recognizable by very low migration thresholds.
- aliphatic amines in some cases have a factor of 100 to 1000 higher permissible migration thresholds. In this respect, purely aliphatic binders are advantageous for such applications.
