The present invention relates to a method of producing a wood based product comprising applying a water-based adhesive composition comprising non-gelatinised starch, the composition further comprises from 0.1 to 50 weight % of one or more polymers (P) containing an amine group or an amide group, onto one or more pieces of a wood-based material and joining the one or more pieces with one or more further pieces of a wood based material.
Description
The present invention relates to a kind of method of producing wood based product.
Foreword
Formaldehyde based resin such as resol, terpolycyantoamino-formaldehyde resin and urea-formaldehyde resin are widely used as the binding agent in wood based product production.The example of this class wood based product is the composite prod that comprises layer glued together as glued board, laminate flooring product and the veneer products that uses in furniture for example.Other example is board products such as shaving board, chipboard and fiberboard, and wherein wood chip and/or xylon are pressed into plank together with binding agent.
When solidifying formaldehyde based resin, formaldehyde not only can be in having made the wood based product process but also can after discharge in use procedure at this product.For many years for healthy reason main what pay close attention to is that formaldehyde is to the release of room air.
For enough bond strength and the finished product total mass are provided so that its needs of formaldehyde-free wood tackiness agent of substitute that are suitable for containing as prior art the tackiness agent of formaldehyde based resin constantly increase.
Usually water-repellancy and bond strength are the key properties of reaction wood base product quality.Usually exist concrete mass parameter to satisfy the requirement of concrete the finished product established standards.For example, shaving board need to satisfy specific criteria as inner combination, thickness swelling and water-absorbent, and the laminate flooring product needed satisfies specific criteria such as delamination and fiber tearing.
Select as another of the binder composition that comprises formaldehyde based resin, be fit to based on the tackiness agent of polymeric dispersions such as polyvinyl acetate ester dispersion.Yet, when by ply is glued together and when this structure is pressed into specified shape and makes compression-moulded product, so-called " resilience " of this glued construction when discharging from mould minimized.The polyvinyl acetate based adhesive is given the resilience result of going on business usually.
It is also important that compression-moulded product in use (namely when standing load) basically keep its shape.This characteristic can be measured by so-called " fatigue test " used in furniture item for example, and wherein compression-moulded product stands many load cycle.
Another selection as formaldehyde based resin in wood adhesive composition has proposed starch-based adhesive.The people such as Imam are at " from the wood adhesive of the pure and mild part jelling starch of crosslinked polyethylene: preparation and performance ", Starch/
