Holzwerkstoffe aus mit Polyisocyanaten verleimten Holzteilen

摘要

The invention relates to derived timber products consisting of wood parts which are glued by means of an adhesive composition, and such adhesive compositions. Said adhesive composition contains a prepolymer (prepolymer P) carrying isocyanate groups and derived from (A) a constituent A containing (A1) between 25 and 100 wt. % of a triglyceride having a plurality of reactive groups which can react with isocyanate groups in an addition reaction (triglycerides A1), and (A2) between 0 and 75 wt. % of another compound having at least one reactive group which can react with isocyanate groups in an addition reaction (constituent A2); and (B) a constituent B containing a polyisocyanate, optionally standard auxiliary and addition agents, optionally an activator, and optionally a filler material.
