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.

A method of using a self-stick insulation. The method includes providing a piece of insulation product with an adhesive coating. The adhesive coating includes polystyrene-maleic anhydride (SMA) and/or polyacrylic acid (PAA); an alcohol amine; and at least one of a polyvinyl alcohol and a starch. The adhesive coating is then activated with liquid water. Once the adhesive coating is active, the insulation product is attached to a surface with the adhesive coating.

This disclosure is directed to a continuous, low-shear process for the compounding and starch. In one aspect of the disclosure, the starch may be applied directly as a web, film, or layer, for example, in a tape product.

Described is an adhesive coating that can be applied, for example, to a surface of the insulation product. The adhesive coating includes between about 15-40% by weight of the adhesive coating of at least one of polystyrene-maleic anhydride (SMA) and polyacrylic acid (PAA), between about 15 and 50% by weight of the adhesive coating of a polyvinyl alcohol, between about 0.05% and 1.0% by weight of a homogenizer, and between about 20 and 40% by weight of the adhesive coating of a starch paste. The adhesive is activated with the application of liquid water.
