摘要： The invention relates to hybrid polyurethane-polymer dispersion with high film hardness, characterized in that it contains the following conversion components: (A) 3 to 25 % by weight of a polyol consisting of (i) 2 to 20 % by weight of a high-molecular weight polyol; (ii) 0.5 to 5 % by weight of a low-molecular weight polyol; (iii) 0.5 to 3 % by weight of a low-molecular weight and anionically modifiable polyol; (B) 2 to 20 % by weight of a polyisocyanate; (C) optionally 0 to 6 % by weight of a solvent consisting of: (i) at least one organic solvent that is inert in relation to a polyisocyanate and/or (ii) a reactive thinner that is inert in relation to polyisocyanates; (D) 0.15 to 1.5 % by weight of a neutralizer; (E) 0.1 to 1 % by weight of a chain extender; (F) 5 to 40 % by weight of a monomer; (G) 0.01 to 1.5 % by weight of an initiator, the remainder consisting of water. The advantages provided by the hybrid polyurethane-polymer dispersion according to the invention such as great hardness and high flexibility of the crackless films, good resistance to chemicals, great stability of the dispersion over a wide pH range, good freeze-thaw stability and the utilization of cost-effective raw materials, are achieved in a simplified synthesis pathway without subsequent chemical cross-linking and with a low content in organic solvent ( /= +10 DEG C.

摘要： The invention relates to a solvent-free polyurethane dispersion having a high solids content of polyurethane polymer or fillers. Said dispersion can be obtained by; a) reacting a high-molecular polyol component (A) (i) with a polyisocyanate component (B) to produce a polyurethane preadduct; b) afterwards, the polyurethane preadduct from step a) is reacted with a low-molecular and anionically modifiable polyol component (A) (iii) having two or more hydroxyl groups and one or more carboxyl groups in order to produce the corresponding prepolymer; c) reacting the prepolymer from step b) with a neutralizing component (C) in order to completely or partially neutralize the carboxyl groups; d) afterwards or simultaneously dispersing the neutralized prepolymer from step c) in water and finally; e) reacting the dispersion from step d) with a chain extending component (D).

摘要： Polyurethane contains an oxidatively drying fatty acid component, comprising unsaturated fatty acid derivative or fatty acid epoxy ester with hydroxyl groups. The dispersion also contains a component obtained by radical polymerisation within the micelles. Self crosslinking polyurethane polymer (PU-P) hybrid dispersion comprises: (A) 0.3-12 wt.% oxidatively drying fatty acid component containing unsaturated fatty acid derivative or fatty acid epoxy ester with at least two isocyanate reactive hydroxyl groups; (B) 1.5-18 wt.% polyol component comprising: (i) 0.5-12 wt.% polymeric polyol with at least two NCO reactive OH groups and a molecular weight = 500-4000, (ii) 0.5-3.0 wt.% low molecular weight polyol with at least two reactive OH groups and a molecular weight = 50-500, (iii) 0.5-3.0 wt.% low molecular weight, anionically modifiable polyol with at least two reactive OH groups, at least one NCO inert carboxyl groups and a molecular weight = 100-200; (C) 3.5-16 wt.% polyisocyanate component comprising polyisocyanate derivatives, with at least two aliphatic or aromatic NCO groups; (D) 0-2 wt.% water emulsifiable active or auxiliary drying agent; (E) 0-8 wt.% solvent comprising: (i) at least one inert (towards polyisocyanate) solvent, that is left in or removed from the final dispersion, and/or (ii) an NCO inert reactive diluent with at least one radically polymerisable double bond; (F) 0.3-2.5 wt.% inorganic or organic base; (G) 0.1-1.5 wt.% polyamine with at least two NCO reactive amino groups as chain extender; (H) 5-45 wt.% monomer with at least one radically polymerisable double bond; (I) 0.05-2 wt.% at least one lipophilic radical initiator, with a half-life of 1 hour at a decomposition temperature of 40-120 deg C; and (J) water. An Independent claim is also included for production of the hybrid dispersion.
