Abstract

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.

First claim

What is claimed is:

1. A method of making a self-stick insulation, comprising:
providing a piece of insulation product;
applying a water activated adhesive coating to a first major surface and a second major surface of the insulation product, the water activated adhesive coating comprising:
between about 30-55% by weight of solids of the adhesive coating of at least one of polystyrene-maleic anhydride (SMA) and polyacrylic acid (PAA);
between about 10-15% by weight of solids of the adhesive coating of an alcohol amine;
water; and
between about 30-60% by weight of solids of the adhesive coating of at least one of a polyvinyl alcohol and a starch; and

drying the adhesive coating on at least the first major surface to evaporate the water to form a dry adhesive coating layer on the surface.

2. The method of claim 1 , comprising coupling a facer to the insulation product with the water activated adhesive coating.

3. The method of claim 1 , wherein the adhesive coating is applied to the first major surface to form a non-continuous and non-uniform coating on the first major surface.

4. The method of claim 1 , wherein the alcohol amine comprises at least one of monoethanolamine (MEA), diethanolamine (DEA) and triethanolamine (TEA).

5. The method of claim 1 , wherein the at least one of polystyrene-maleic anhydride (SMA) and polyacrylic acid (PAA) have a molecular weight of 500 to 5,000 g/mol.

6. The method of claim 1 , wherein the insulation product comprises 1-8% by weight of the adhesive coating after the adhesive coating is applied and dried to the insulation product.

7. The method of claim 1 , further comprising a facer adhered to the second major surface of the insulation product via the adhesive coating.

8. The method of claim 7 , wherein the facer comprises at least one material selected from the group consisting of a paperboard material, a cardboard material, a foil, a scrim, and a polymer material.

9. The method of claim 7 , wherein the facer comprises one or more flanges that extend beyond an edge of the second major face of the insulation product.

10. The method of claim 1 , wherein the insulation product comprises at least one material selected from the group consisting of fiberglass, mineral wool, slag wool, rock wool, and foam.

11. The method of claim 1 , wherein the adhesive coating passes a D 903 bonding strength (Ambient) test based on standards of ASTM C 916.

12. The method of claim 1 , wherein the adhesive coating passes a C 916/D1 151 Bonding Retention (90 days@ 160° F.) test based on standards of ASTM C 916.

13. The method of claim 1 , wherein the adhesive coating passes a C 916 Edge Burning test based on standards of ASTM C 916.

14. A method of using a self-stick insulation, comprising:
providing a piece of insulation product with an adhesive coating on a first major surface and a second major surface of the insulation product, wherein the adhesive coating comprises:
between about 30-55% by weight of solids of the adhesive coating of polystyrene-maleic anhydride (SMA) and/or polyacrylic acid (PAA);
between about 10-15% by weight of solids of the adhesive coating of an alcohol amine; and
between about 30-60% by weight of solids of the adhesive coating of at least one of a polyvinyl alcohol and a starch;

activating the adhesive coating on the first major surface, the second major surface, or both the first major surface and second major surface with liquid water; and
attaching the insulation product to a surface with the adhesive coating.

15. The method of claim 14 , comprising repositioning the insulation product on the surface before the adhesive coating dries.

16. The method of claim 14 , wherein the alcohol amine comprises at least one of monoethanolamine (MEA), diethanolamine (DEA) and triethanolamine (TEA).

17. The method of claim 14 , wherein the at least one of polystyrene-maleic anhydride (SMA) and polyacrylic acid (PAA) have a molecular weight of 500 to 5,000 g/mol.
