Description

C. DISCUSSION OF PRIOR ART AND BACKGROUND OF THE INVENTION

The application of protective roofing sheets, particularly rubber roofing sheets, to the upper surface of a roof, involves the use and application of an adhesive product applied to the upper surface of the roof infrastructure. After a minimum limited waiting period of approximately ten minutes, the bottom surfaces of the roofing sheets are adhered flush against the upper surface portion of the roof infrastructure on which the adhesive material is applied. This minimum waiting period causes problems of the inefficiency in the overall installation process. This adhering process is adapted to create a firm bond between the upper surface of the roof structure and the roof covering sheets, and with the adhesive undersurface it creates a more substantial moisture barrier to protect the integrity of the roof.

In the existing art, the adhesive glues or other substances presently used to create this adhesion between the covering sheets and roof structure generally have a significantly high viscosity. Because of this high viscosity, the process of applying the adhesive substance to the roof infrastructure requires a heavy duty, high pressure spray mechanism that involves expensive equipment. Moreover, because of the significant viscosity of the adhesive substance used in this context, the sprayer must be cleaned internally after each use, with solvents usually involving high pressure injections. This itself has proven to be a time consuming procedure.

Yet another consideration that is of significance in the use of existing adhesive substance or glues is that when applied to the upper surface of the base roof structure the adhesive substance usually causes isolated globs or other imperfections in the relative smoothness of the adhesive layering. These globs or imperfections potentially eventually lead to blistering or bubble-like rises which ultimately lessen the adhesive strength the bond between the rubber roof sheets and the base roof structure.

Another problem in the use of existing adhesive material for fixing rubber roof sheets to a building structure is the toxicity and environmental aspect. Almost all existing adhesive substances on the market and in use today are comprised of chemicals that are dangerous to the environment and potentially toxic to humans. Because of this latter suspect and the other problems above discussed there is a pressing need for improved adhesive substances in this area.

E. DESCRIPTION OF GENERAL EMBODIMENT AND SUMMARY OF INVENTION

The subject invention is a process for applying adhesive product for adhering roof covering sheets to the upper surface of a building, such process comprising applies in the following products in various combination ratios:

• • (a) synthetic rubber and resin;
  • (b) toluene;
  • (c) cyclohexane;
  • (d) dearomatised petrol;

With such product being applied by utilizing a spraying device to apply such product in an even layered film and then adhering to the bottom surfaces of a roofing sheet over such applied film. This positioning of the rubber roof sheets is preferably consummated immediately after the application of the adhesive product. Additionally certain other compounds may be added to the above product to minimize the viscosity of the product and render the product more compatible with the environment.

In using this general formulation to apply rubber roof sheets or other types of roof sheets to the upper surface of a roof, the product and process above described generates a less viscous adhering substance that can for a given volume of advance can cover, in some situations approximately ten times the surface area that existing adhering products are capable of covering. This aspect therefore means that a given volumetric unit of the subject product can replace a larger quantity of the existing adhering products to accomplish the same end result if adhering roofing sheets. Additionally, the subject product as applied with the given process, as generally described has a substantially greater adhering capability and strength, with longer lasting adhering effects.

Further, in using the subject product there is no necessity to use a high pressure sprayer to apply the adhesive material by reason of a lower viscosity and no need use expensive time consuming procedures to clean the sprayer after each use. Indeed, most low pressure sprayers will be adequate to accomplish the spraying process in applying the subject adherent. Further the adhering substance herein can also be sued to spray and coat the insulation material used in the roofing infrastructure in order to protect the integrity thereof. The environmentally compatible aspects are such that the composition is easy to disintegrate into a relatively harmless way into the environment.

An additional attribute of this product is that the substance herein dries more quickly without bubbling and as a result the roofing sheets can be applied more quickly so as to render the overall adhesive and installation process more efficient, with the end product having a greater adhesive quality.
