Coated fabrics including expandable graphite
A method for preparing a roofing membrane in the form of a roll, comprising the steps of: providing a polymeric membrane; providing a fabric having a coating disposed thereon; attaching the polymeric membrane to the fabric to form a composite; and rolling the composite. Wherein the coating includes expandable graphite dispersed within a binder.
1. A method for preparing a roofing membrane in the form of a roll, comprising the steps of:
(i) providing a roofing membrane;
(ii) providing a fabric having a coating disposed thereon, where the coating includes expandable graphite dispersed within a binder;
(iii) attaching the roofing membrane to the fabric to form a composite; and
(iv) rolling the composite.
2. The method of claim 1 , where the roofing membrane is a thermoplastic membrane, and where said step of attaching includes mating the fabric to the roofing membrane while the roofing membrane is in a molten or semi molten state.
3. The method of claim 1 , where the roofing membrane is a rubber membrane, and where said step of attaching includes adhesively attaching the roofing membrane to the fabric.
4. The method of claim 1 , where the expandable graphite has an onset temperature of at least 170° C.
5. The method of claim 1 , where the expandable graphite has an onset temperature of at least 180° C.
6. The method of claim 1 , where the coating is devoid of an inorganic binder.
7. The method of claim 1 , where the binder is a polymeric binder.
8. The method of claim 1 , where the roofing membrane is an asphaltic membrane, and where said step of attaching includes mating the fabric to the roofing membrane while the roofing membrane is in a molten or semi molten state.
