Definitions
- the present invention is in the field of rigid polyurethane foams.
- it relates to the production of rigid polyurethane foams using special polymer particles, and also to the use of the foams that were produced therewith.
- thermosetting insulating foams For the production of thermosetting insulating foams, it may be desirable, for example, to produce hard foams with a preferably relatively low density of ⁇ 60 kg / m 3 and preferably as many small closed cells as possible (high cell density).
- the cells should preferably be evenly distributed over the entire molded part, ie should not have a gradient.
- a propellant gas is required so that a foam can form.
- This can be e.g. CO2, which is formed from the reaction of isocyanate with water or is additionally added, and / or an added low-boiling organic liquid.
- WO 2002/034823 describes, for example, an extrusion process on thermoplastics that leads to the formation of multimodal thermoplastic polymer foams.
- the systems of non-thermoplastic, but rather thermoset polyurethane foams considered here as preferred, on the other hand, are preferably distinguished by a generally uniform, monomodal cell size distribution and cannot be obtained by extrusion processes either.
- cell-stabilizing additives are usually used, which are intended to ensure a fine-grained, uniform and low-disruption foam structure and thus have a positive effect on the properties of use, especially the thermal insulation capacity of the rigid foam.
- Surfactants based on polyether-modified siloxanes which are therefore the preferred type of foam stabilizer, are particularly effective.
- EP1544235 describes typical polyether-modified siloxanes for PU rigid foam applications.
- siloxanes with 60 to 130 Si atoms and different polyether substituents R whose mixed molar weight is 450 to 1000 g / mol and whose ethylene oxide content is 70 to 100 mol%, are used.
- WO2009092505A1 describes a process for the production of polyurethane or polyisocyanurate insulating foams on the basis of foamable reaction mixtures containing polyisocyanates, compounds with reactive hydrogen atoms, blowing agents, stabilizers, nucleating agents and optionally other additives, with porous solids as nucleating agents, in particular silicates with a zeolite structure, be used.
- PU foams in particular rigid PU foams, based on foamable reaction mixtures containing polyisocyanates, compounds with reactive hydrogen atoms, blowing agents, foam stabilizers, and optionally other additives, with polymer particles additionally being used, the mean particle size of the polymer particles ⁇ 100 ⁇ m, preferably ⁇ 70 ⁇ m, in particular 5 to 50 ⁇ m, solves the problem.
- This method is the subject of the invention.
- polyurethane is understood to mean, in particular, a product obtainable by reacting polyisocyanates and polyols or compounds with isocyanate-reactive groups.
- other functional groups can also be formed, such as uretdiones, carbodiimides, isocyanurates, allophanates, biurets, ureas and / or uretimines.
- PU therefore means both polyurethane and polyisocyanurate, polyureas and polyisocyanate reaction products containing uretdione, carbodiimide, allophanate, biuret and uretimine groups.
- polyurethane foam is understood to mean, in particular, foam which is obtained as a reaction product based on polyisocyanates and polyols or compounds with isocyanate-reactive groups.
- other functional groups can also be formed, such as allophanates, biurets, ureas, carbodiimides, uretdiones, isocyanurates or uretimines.
- PU foams in the context of this invention also includes what are known as polyurethane foam moldings, in particular hard polyurethane foam moldings.
- the polymer particles to be used according to the invention are distinguished by the fact that the mean grain size of the polymer particles is ⁇ 100 ⁇ m, preferably ⁇ 70 ⁇ m, in particular 5 to 50 ⁇ m.
- the mean grain size (volume mean) of the polymer particles is determined based on ISO 13320-1 by means of laser diffraction spectroscopy.
- the polymer particles to be used according to the invention and their production processes are known per se.
- the polymerization of ethylenically unsaturated compounds is well known.
- Corresponding polymer particles are also commercially available, e.g. corresponding polymethyl methacrylate particles, e.g. available from Evonik Industries AG as DEGACRYL®.
- Mw molecular weights for the polymethyl methacrylate are in the range from 200,000 to 1,500,000, preferably 300,000 to 1,000,000, in particular 350,000 to 700,000, Mw determinable in accordance with DIN 55672-1.
- the polymer particles are made of polymer including polyethylene (PE), polypropylene (PP), polyamide (in particular including PA6, PA6.6, PA10, PA11 and / or PA12), polyester (in particular including PET, PBT and / or PCL), polystyrene, polyacrylate, polymethyl methacrylate, polycarbonate, styrene-acrylonitrile copolymers, polyether, polylactic acid, polyurethane, polysulfones, polyether sulfone, polyetherimide, polyimide or mixtures thereof, in particular comprising polystyrene and / or polymethyl methacrylate, are formed.
- PE polyethylene
- PP polypropylene
