No-Added Formaldehyde Binder For Composite Wood Product And the Composite Wood Product Manufactured By The Same

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.
