    摘要: An adhesive composition for lignocellulose-type hot-pressed forms is disclosed which comprises (A) an organopolyisocyanate which is a polyisocyanate composed chiefly of from 20% by weight to 70% by weight of a diphenylmethane diisocyanate having two benzene rings in one molecule and from 80% by weight to 30% by weight of a diphenylmethane diisocyanate polynuclear condensate having at least three benzene rings in one molecule, and has a viscosity of 500 mPa·s or less in the state of solid content=100% by weight at 25° C.; and (B) a wax emulsion prepared by emulsifying a wax (B1) which is a paraffin wax containing at least 80% by weight of a paraffin having 20 to 40 carbon atoms, and has a melting point of from 40° C. to 100° C., with an emulsifier (B2) which is an ethylene oxide polyaddition product of an aliphatic monoalcohol whose aliphatic chain has 14 to 20 carbon atoms. Also disclosed is a process for producing lignocellulose-type hot-pressed forms, using this adhesive composition. The adhesive composition has a good releasability from heating platens used in hot-press forming.

    摘要: A joint between two components (2, 4), with both components (2, 4) having joint faces (6, 8) which at least partially correspond with one another, which at least partially press against one another in the jointed state. The technical problem, on one hand, of preserving the advantages of an adhesive joint in comparison to mechanical joining systems, but simultaneously not increasing the outlay by the consumer and the outlay for handling the components, is solved in that a matrix (14, 16) is positioned on at least part of at least one of the joint faces (6, 8), multiple capsules (18) are positioned distributed in the matrix (14), a material of a reaction adhesive system is contained in the capsules (18), and at least a part of the capsules (18) at least partially release the material contained in them under external action. Also, a component having at least one joint face and a method for producing an adhesive matrix on a joint face.

    摘要: A process for the production of a modified phenol-aldehyde resin which may form a binder system when combined with a curing agent which includes an additional source of an aldehyde, e.g., a phenol-formaldehyde resin. The inventive phenol-aldehyde resin may be modified with compounds from one of the following classes: (1) dihydroxybenzenes, (2) aminophenols, and (3) phenylenediamines. The resin and adhesive are useful in the production of a wood composite (such as plywood, oriented strandboard, or fiberboard).
