| titleOfInvention | Method for producing lignocellulose materials |
| abstract | The invention relates to a novel and improved discontinuous or continuous, preferably continuous method for producing single-layer or multi-layer lignocellulose materials, containing the following method steps: (Ia) producing a mixture M1 and (Ib) optionally at least one mixture M2, (II) scattering the mixture M1 and optionally the mixture(s) M2 to form a mat, (III) optionally precompressing the scattered mat and (IV) hot-pressing, where the mixture M1 contains the lignocellulose particles (component LCP-1) and additionally a) between 0.005 and 0.5 wt. % of organic carboxylic acid, carboxylic acid anhydride, carboxylic acid chloride or the mixtures thereof (component A), b) between 0.05 and 3 wt. % of organic isocyanate with at least two isocyanate groups (component B), and c) between 5 and 15 wt. % of binder selected from the group of aminoplastic resins (component C), d) between 0 and 2 wt. % of hardener (component D), and e) between 0 and 5 wt. % of additive (component E); and the mixture(s) M2 contain the lignocellulose particles (component LCP-2) and additionally f) between 0 and 0.3 wt. % of organic carboxylic acid, carboxylic acid anhydride, carboxylic acid cloride or the mixtures thereof (component F), g) between 1 and 30 wt. % of binder selected from the group consisting of aminoplastic resin, phenoplastic resin, protein-based binder and other polymer-based binder or the mixtures thereof (component G-1) and between 0 and 3 wt. % of organic isocyanate with at least two isocyanate groups (component G-2), h) between 0 and 2 wt. % of hardener (component H), and i) between 0 and 5 wt. % of additive (component I), provided that the following conditions are met: amin < a < amax and amin = [(- 1/6000 • T) + (65/6000)], preferably amin = [(- 1/4500 • T) + (65/4500)], particularly preferably amin = [(- 1/3500 • T) + (65/3500)] and amax = [(- 1/2000 • T) + (75/2000)], preferably amax = [(- 1/2500 • T) + (75/2500)], particularly preferably amax = [(- 1/3000 • T) + (75/3000)], where T is the temperature of the mixture M1 in °C following the method step (Ia) and this is between 10 and 65°C, preferably between 12 and 62°C, particularly preferably between 15 and 60°C, and a is the quantity of acid equivalents of the component A) in relation to the mass of components C) in mol/100g. |
