Abstract
A water-based adhesive for the manufacture of laminated cellulosic boards includes monolayer graphene oxide as a glue enhancer. Laminated cellulosic boards may be obtained by providing cellulosic plies, applying a water-based adhesive, and contacting the surface of another cellulosic ply to the first cellulosic ply. A method for producing the water-based adhesive includes mixing starch, water and glue enhancer. The glue enhancer is a suspension of between 0.1 wt % and 0.001 wt % of monolayer graphene oxide in water.
Claims7
Use of monolayer graphene oxide as a glue enhancer for a water-based adhesive for the manufacture of laminated cellulosic boards, wherein the water-based adhesive comprises:
- 1) water;
- 2) between 20.0 wt % and 40.0 wt % starch;
- 3) optionally, up to 10 wt % of at least one further polymer, selected from natural polymers or soluble synthetic polymers;
- 4) a glue enhancer, comprising monolayer graphene oxide in water, in an amount such that the water-based adhesive comprises between 0.1 wt % and 10-7 wt % of monolayer graphene oxide;
- and
- 5) at least one further component, selected from fungicides and biocides, and/or stabilizing agents, gelling agents, thickening agents, anti-foaming agents, tackifyers, damp-proofing resins, rheology agents in accordance with the polymer(s).
