Abstract

Nail sealable materials comprising a matrix material and bentonite embedded within the matrix material are described herein in accordance with non-limiting embodiments of the present disclosure. In some embodiments, the nail sealable material comprises a sufficient amount of bentonite, such that the nail sealable material passes ASTM D1970 at a specified nail sealable material test thickness. Some embodiments relate to systems and methods utilizing the nail sealable materials described herein.

First claim

What is claimed is:

1. A system comprising:
a sheet of a nail sealable material, wherein the sheet of the nail sealable material comprises:
a matrix material, wherein the matrix material comprises asphalt;
bentonite, wherein the bentonite is embedded within the matrix material; and

a building substrate,
wherein the building substrate is a roof deck;
wherein the roof deck has at least one surface;
wherein the nail sealable material is disposed on the at least one surface; and

a plurality of nails, wherein the sheet of the nail sealable material is affixed to the at least one surface of the roof deck by the plurality of nails, wherein the plurality of nails extend through the sheet of the nail sealable material;
wherein the sheet has a thickness of from 0.04 inches to 0.1 inches and comprises a sufficient amount of bentonite so as to result in a passing grade when the sheet is tested according to ASTM D1970 at a nail sealable material thickness of 0.04 inches.

2. The system of claim 1 , wherein the matrix material is present in the nail sealable material in an amount ranging from 25 wt % to 70 wt % based on a total weight of the nail sealable material.

3. The system of claim 1 , wherein the asphalt is present in the matrix material in an amount ranging from 30 wt % to 100 wt % based on a total weight of the matrix material.

4. The system of claim 1 , wherein the asphalt is a polymer modified asphalt.

5. The system of claim 1 , wherein the asphalt is oxidized asphalt.

6. The system of claim 1 , wherein the bentonite is present in the nail sealable material an amount ranging from 30 wt % to 75 wt % based on a total weight of the nail sealable material.

7. The system of claim 1 , wherein the bentonite is sodium bentonite, potassium bentonite, calcium bentonite, aluminum bentonite or any combination thereof.

8. The system of claim 1 , further comprising at least one fill material, wherein the at least one fill material is embedded within the matrix material.

9. The system of claim 8 , wherein the at least one fill material comprises at least one of: limestone, talc, kaolin, alumina trihydrate, magnesium hydroxide, rice hulls, ground tire rubber, or any combination thereof.
