Zusammenfassung:	Provided are an emulsifiable isocyanate composition and a preparation method therefor. The emulsifiable isocyanate composition comprises the following components: (a) a polymethylene polyphenyl polyisocyanate, (b) an emulsifier, (c) an adduct derived from a diisocyanate, and optionally (d) a terpene monomer. The emulsifiable isocyanate composition is used for an artificial board adhesive, and has a smaller mold cumulative effect, an improved demouldability and an extended active period. L'invention concerne une composition d'isocyanate émulsifiable ainsi que son procédé de préparation. La composition d'isocyanate émulsifiable comprend les constituants suivants : (a) du polyméthylène polyphényle polyisocyanate, (b) un émulsifiant, (c) un produit d'addition dérivé d'un diisocyanate, et éventuellement (d) un monomère terpénique. La composition d'isocyanate émulsifiable est utilisée pour un adhésif de panneau artificiel, et offre un effet cumulatif en moule plus faible, une aptitude au démoulage améliorée et une période active prolongée.
