Composite material, useful e.g. as nitrogen-phosphorus-potassium fertilizer, comprises superabsorber polymer, (in)organic filler, soil additive, binding agent and solid and/or liquid fermentation residues fermented from biomass

摘要

Composite material comprises (a) at least one natural and/or synthetic superabsorber polymer; (b) at least one organic and/or inorganic filler and/or soil additive preferably based on eruptive rock, organic and/or inorganic fertilizer preparation and/or organic, also present in fiber form, and/or inorganic aggregate, active ingredient and/or binding agent; and (c) solid and/or liquid fermentation residues fermented from biomass. Composite material comprises (a) at least one natural and/or synthetic superabsorber polymer; (b) at least one organic and/or inorganic filler and/or soil additive preferably based on eruptive rock, organic and/or inorganic fertilizer preparation and/or organic, also present in fiber form, and/or inorganic aggregate, active ingredient and/or binding agent; and (c) solid and/or liquid fermentation residues fermented from biomass, where (a) is from hydrogel composite, and the amount of (a) is = 2 wt.% and at least the 5-times of its dead weight of (a) under time-dependant increase in the volume of waters and/or aqueous solutions is stored and again delivered. An independent claim is included for the preparation of the composite material comprising mixing and/or kneading the above components in an input or two-screw mixer and/or one or two-shaft plowshare mixer.
