Abstract
Disclosed is a building and construction material and process including multiple layers and vermiculite ore in at least one layer. A substrate layer may have one or more layers on top or on the bottom of it. Numerous compounds may be used in one or more of the layers including asphaltic compound, polymer modified asphalt compound, thermoplastic polymer compound and others. The layers may also include synergistic flame retardant and fillers. And disclosed is a process to manufacture the building and construction material.
Claims27
A building construction material comprising:
- a minimum of 2 layers;
- at least one compound layer:
- at least one substrate layer;
- and
- vermiculite ore incorporated in at least one of the layers.
A process for manufacturing a building construction material comprising:
- selecting the building construction material comprising:
- a minimum of 2 layers;
- at least one compound layer:
- at least one substrate layer with a top side and a bottom side;
- and vermiculite ore incorporated in at least one of the layers;
- selecting at least one compound for each layer of the building construction material;
- blending one or more selected compounds including additives and fillers as desired prior to application on a manufacturing line;
- applying a selected compound layer onto at least one side of the substrate layer on the manufacturing line for a selected layer when the selected compound is at a desired temperature;
- calendaring the selected compound layer to obtain a desired thickness so that the substrate layer is at least partially saturated;
- applying the vermiculite ore to the selected compound layer by depositing the vermiculite ore onto the selected compound layer using an applicator;
- applying a surfacing as desired;
- and
- cooling, cutting, and packaging the building construction material to a desired length.
