  • No-added formaldehyde binder for composite wood product and the composite wood product manufactured by the same
    Patent number: 11806892
    Abstract: Disclosed a no-added formaldehyde composite wood product binder, a no-added formaldehyde composite wood product manufactured by same, and a preparation method for the composite wood product. The no-added formaldehyde composite wood product binder comprises an agent A and an agent B. The agent A is an isocyanate-based binder, and the agent B is an aqueous dispersion of polyester based aliphatic polyurethane and/or a modified polyester-based aliphatic polyurethane. The no-added formaldehyde composite wood product is formed under hot-pressing after a wooden and/or straw material is mixed with the no-added formaldehyde composite wood product binder. The composite wood product manufactured by the no-added formaldehyde composite wood product binder has excellent water-proof and mechanical properties and a good saw cutting performance, and the amount of isocyanate used is also reduced, thereby reducing costs.

  • Emulsifiable isocyanate composition and preparation method and use thereof
    Patent number: 10787593
    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.
