Abstract

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 in artificial board adhesives, and has a smaller mold cumulative effect, an improved demoulding performance and an extended pot life.
