摘要： A solvent-free polyurethane-polymer hybrid dispersion having a high solids content of polymer or formulation constituents is described, which is obtainable by a) the multistage preparation of a polyurethane base dispersion and b) by the subsequent preparation of a polyurethane--polymer hybrid dispersion. This polyurethane-polymer hybrid dispersion not only is distinguished by complete freedom from solvents and high solids contents in combination with low viscosity and a technically simple preparation process but also has excellent mechanical properties and, owing to the low hydrophilicity, high water resistance. The polyurethane-polymer hybrid dispersion proposed according to the invention can be used in an outstanding manner in formulations for sport floor coverings, said dispersion being suitable in particular as a binder for resilient coats, as a spray or leveling coating on resilient or rigid substrates, as an adhesion promoter or primer, as filling compounds for sealing pores, as adhesive for the adhesive bonding of prefabricated resilient layers or for the sealing of sport floor coverings.

Solvent-free polyurethane-polymer hybrid dispersions (I) with a high solid content, obtained by: (a) production of a polyurethane base dispersion by: (a1) reacting 2-40 wt.% of a high molecular weight polyol component (A-i) with a molecular weight of 500-6000 and two or more isocyanate-reactive hydroxyl groups and optionally 0.1-2 wt.% of a polyol component (A-ii) with a molecular weight of 60-150 and at least two NCO-reactive OH groups with 2-20 wt.% polyisocyanate component (B) (polyisocyanate and/or derivatives and/or homologues) with 2 or more aliphatic or aromatic NCO groups (optionally in presence of catalyst); (a2) reacting the pre-adduct with 0.1-2 wt.% of an anionically modifiable polyol component (A-iii) containing 2 or more reactive OH groups and one or more isocyanate-inert carboxyl groups which can be converted into carboxylate with base; (a3) partly neutralizing the prepolymer from (a2) with 0.1-1.5 wt.% of a neutralizing agent (C); (a4) dispersing in 10-60 wt.% water (optionally containing 0.1-70 wt.% of formulating component(s) (F) for in-situ formulation i.e. fillers, pigments, plasticizers, fibres etc.); and (a5) reacting with 0.1-2 wt.% of a chain extender (D) (polyamine with reactive amino group(s)) and optionally 0.05-1 wt.% of a mono-amine chain stopper (E); followed by (b) production of a hybrid dispersion by: (b1) mixing the dispersion from (a5) with a mixture of 3-60 wt.% of unsaturated monomer(s) (G) and 0.01-1 wt.% of an initiator component (H), comprising lipophilic radical initiator(s) with a half-life of 1 hour at 40-120 deg C; and (b2) radically polymerizing (G) in the micelles of the base dispersion.

摘要： Described is a polyurethane/polymer hybrid dispersion with high film hardness, which comprises the reaction components(A) from 3 to 25% by weight of a polyol component consisting of(i) from 2 to 20% by weight of a relatively high molecular mass polyol component,(ii) from 0.5 to 5% by weight of a low molecular mass polyol component,(iii) from 0.5 to 3% by weight of a low molecular mass and anionically modifiable polyol component,(B) from 2 to 20% by weight of a polyisocyanate component,(C) if desired, from 0 to 6% by weight of a solvent component consisting of(i) at least one polyisocyanate-inert organic solvent and/or(ii) a polyisocyanate-inert reactive diluent,(D) from 0.15 to 1.5% by weight of a neutralizing component,(E) from 0.1 to 1% by weight of a chain extender component,(F) from 5 to 40% by weight of a monomer component,(G) from 0.01 to 1.5% by weight of an initiator component,and water as the remainder.The advantages of the polyurethane/polymer hybrid dispersion of the invention, such as high hardness coupled with high flexibility of the crack-free films, good chemical resistance, great stability of the dispersion within a wide pH range, good freeze/thaw stability, and the use of inexpensive raw materials, are achieved in a simplified synthesis route, without subsequence chemical crosslinking, with a simultaneously low organic solvent content (

摘要： The invention relates to a solvent-free polyurethane-polymer-hybrid-dispersi on containing a large proportion of solid polymer or formulation constituents. Said dispersion is obtained by: a) producing a polyurethane base dispersion in multiple stages and; b) then producing a polyurethane-polymer-hybrid- dispersion. This polyurethane-polymer-hybrid-dispersion is characterised not only by its complete lack of solvents, in that it contains a high proportion of solids while having a low degree of viscosity, and by a technically simpl e production method but also in that it has excellent mechanical properties an d a high degree of water resistance due to its low hydrophilicity. The inventi ve polyurethane-polymer-hybrid dispersion is excellently suited to use in formulations for coverings of floors used for sporting activities, especiall y as a binder for elastic layers, as a spray or levelling coating on elastic o r rigid bases, as a bonding agent or filler, as filler materials for pore- sealing, as an adhesive for sticking pre-fabricated elastic layers or for sealing coverings of floors used for sporting activities.

摘要： The invention relates to the use of aqueous, isocyanate-free, polyurethane dispersions with a solid content of 30 wt.% and a solvent content of 10 wt.% in sports floor coverings. The inventive polyurethane dispersions are particularly suitable for use as bonding agents for elastic coatings, spray coatings or flow coatings on elastic or rigid undersurfaces, adhesion promoters or primary coatings, fillers for sealing pores, adhesives for glui ng pre-fabricated plastic coatings or for sealing sports floor coverings. The inventive polyurethane dispersions are environmentally friendly and easy to manufacture. They are also partly characterised by improved product features , e.g. mechanical properties, UV resistance and colour stability, with respect to the corresponding sports floor coverings.
