Abstract: Aqueous solutions of adhesive resins made from formaldehyde, urea, melamine and phenol are obtained if phenol, formaldehyde and up to 0.35 mol of an alkaline metal bisulphite per mol of phenol are reacted to give a phenol-formaldehyde condensate and formaldehyde and urea in a molar ratio of 2.5 or less are reacted to give a urea-formaldehyde condensate, and the reaction products are themselves reacted with melamine and formaldehyde.

Abstract: Thermosetting binder for wood materials contains (i) an aq. epoxy resin dispersion, prepd. by emulsifying esp. reaction prods. of epichlorohydrin and polyvalent phenols with a reactive protective colloid in water, together with (ii) a polyamino-amide resin dispersion. Pref. 5-15% binder mixt. is used, calcd. as dry solids w.r.t. absolutely dry wood raw materials. The mixt. consists, by wt., of 10-30% aq. epoxy resin dispersion, 10-50% aq. polyamine-amide resin dispersion, up to 10% emulsifiers and opt. subordinate quantities of hardening accelerators, standard additives and balance water. Equiv. wt. ratio epoxy- to polyamine-amide ratio is 0.8-1.6. Binder liquor water content is at least 30%. Light-coloured fibre- and chip-board, veneers and articles can be produced, which (a) do not release HCHO, during or after hardening and (b) have high bending- and cross-sectional strength.

Abstract: Prepn. of aq. polyisocyanate emulsions involves dispersing or emulsifying the polyisocyanates in water in the presence of an emulsifier based on a polyglycol of molecular wt. 4,000-20,000, or a polyvinyl alcohol of molecular wt. 5,000-100,000. The polyisocyanate is pref. the phosgenated reaction product of aniline and formaldehyde. The emulsion can also be prepd. in the additional presence of a polypeptide. The emulsions are used for the glueing together of wood chip panels.
