ing iquids as a method for waterproofing and preserving surfaces, and while some of these prior methods have proven highly satisfactory,'it isthe purpose of the present invention to materially improve upon prior 16 waterproofing compounds, whereby to overcome existing defects, and to this end the product contemplated by the present inven tion is a waterproof, acid and alkali proof, fire-retarding composition, in semi-liquid or 20 plastic form, which may be readily applied over roofs or other surfaces, to the desired thickness, forming a tenacious, protective coating, thereby eliminating rust, rot, corrosion, etc.
- Various changes and improvements over existing methods will be appreciated by those familiar with the art, from the following detailed description, it being understood in this connection that whereas in the preferred embodiment of the invention as described, certain asphalts, semi-drying and waterproofing oils, etc., are specified, and in certain preferred proportions, many advan tages of the invention maybe obtained by a substitution and possibly reproportioning of other materials having substantially the same properties or qualities as those herein specified, and such obvious changes are Within the contemplation of the present invention. A novel and improved base for waterproofing compounds in the preferred cmodiment of my invention, is made up asv follows:
Native or natural'rock asphalts, prefer.- ably gilsonite and elaterite, in the relative proportion of approximately ten to seven parts, respectively, or other native highmelting asphalts having similar melting points and acid-resistingqualities, are employed. It has been ascertained that a comination of gilsonite and elat'erite when treated with m'aterials'to be referred to, will produce a base product that will remain 65 plastic under extremes of temperature and Application filed April 15, 1925. Serial No. 23,379.
stand all other required tests. In order to properly thin the asphalts, whereby the same may be spread readily over the surface to be treated, etc., it is proposed to add an admixture of properly cooked China wood or tung oil and a semidrying oil such as properly cooked soya bean oil. The China wood or tung oil renders the composition considerably more Waterproof, and the addition of the soya bean oil or other suitable drying oil makes the composition more elastic and revents it from drying out in a brit-' tle con ition. The so a bean oil is slow in oxidizing, While the hina wood oil is high in waterproofing properties, and when successfully combined with the plastic base of asphalt, there results a plastic, non-oxidizing material of heavy body that can be easil spread in a relatively thick layer which wil l not run or curtain under an extremely high degree of heat, nor freeze or crack at an extremely low temperature. The properly cooked China wood or tung oil and the soya bean oil conveniently have the proportions of approximately, soya bean oil fourteen parts and Chinav wood oil or tung oil seven parts, in the compound; and the materials just described combine to provide a much improved base over existing bases for waterproofing compounds. I
In order to apply to the compound the desirable tensile strength such as required to carry over cracks and holes in the underlying surface and cause it to withstand the strain of expansion and contraction, and in the event the compound is applied to the roofs of cars, to withstand the incident jarring and vibration, it is proposed to incorporate .into the base, asbestos fibre preferably in the proportion of approximately twenty-eight parts. It is desirable to utilize an asbestos fibre of a grade high in absorbing pro erties, preferably pure rock asbestos fi re. This fibre increases the tensile stren and imparts to the composition a heavy ody so that the coating may be applied ina heavy layer and flow out smoothly and easily.
In order to overcome the effect of the actinic rays of the sun, it is proposed to increase the density of the coating and shut 106 out the light entirely by the use of an inert black pigment, preferably in the proportion of approximately one part.
Suitable volatile thinners are added to the product, preferably in the proportion of ap- 11o proximately thirty-three parts, whereby the comfiund may be spread over the surface rea y and smoothly under the action of a brush or the like.
While the compound has been described as useful primarily in the coating and waterproofing of exposed surfaces such as roofs, walls, and the like, the same may be equally serviceable in other connections, and has been succesfully employed for waterproofing and coating water tanks and the like. one of the properties of the present compound being that it is non-contaminating and water may be freely and harmlessly used for human consumption after contact with said compound.
Some of the other advantages of the present compound herein contemplated may be said to reside in the non-porous character thereof, the rock asphalts and oils employed bemg non-porous, thus preventing the pas- Sage of moisture or air through the coating. Again, the ingredients of the compound are proofs against acids and alkalis. thus protecting all metals from corrosion. Due to the adhesive properties inherent in the 'compound, the same will readily adhere to any material such as glass, and all porous surfaces such as composition roofing. wood, can vas, etc., and will also readily adhere to wet surfaces, thereby making possible the repair of leaks during storms, if desired. The composition of matter herein contemplated is also of a character that will not crack or peel since its elasticity is such that it will expa'nd and contract with the under surface under varying degrees of heat, but will not run under high temperatures nor crack under low temperatures. The composition alsohas certain heat insulating 'properties, ithaving been ascertained that the temperature below a metal roof, for instance, covered with the present composition is considerably less than the tem rature under'a painted or bare metal roo under the same sun heat.
, Further, it has been ascertained that when dried and cured, the waterproofing compound herein contemplated will resist fire to a .degree, and will withstand a much higher degree of heat than felt or paper com 'tion roofing.
Thg new composition of matter herein contemplated is normally in a semi-liquid form and may be applied with a brush to the surface to be waterproofed, and is of such consistency that it may be applied in a heavy film many times thicker than a paint film, and the material, because of its make-up,
will be kept soft and elastic by forming a surface film which protects the underlying portion from too rapid oxidation and from the actinic rays of the sun. which, as understood, have a well-known influence in rapidly destroying asphalts Coupled with'the other advantages, may be noted the strength and durability of the compound.
What I claim as new, is:
1. In a waterproofing composition, the combination of natural rock asphalt having high melting properties, China wood oil, and soya bean oil.
2. In a waterproofing composition, the
combination of a mixture of gilsonite, elaterite, China wood oil. and soya bean oil.
3. In a waterproofing composition. the combination of asbestos fiber incorporated in an admixture of native rock asphalt, soya bean oil, and China wood oil.
4. In a composition of the character described, the combination of a base includin gilsonite, elaterite, soya bean oil. China wood oil, and rock asbestos fiber.
5. In a waterproofing composition, the combination of natural rock asphalts, China wood oil, soya bean oil. asbestos fiber, and black pigment.
6. In a waterproofing composition of the character described. the combination of an admixture of natural rock asphalts. China wood oil, soya bean oil, rock asbestos fiber, an inert pigment, and a volatile thinner.
7. The improved process of forming waterproofing compositions which consists in mixing natural rogk asphalts, China wood oil, and soya bean oil; incorporating in the base formed by said mixture. rock asbestos fiber. and adding a volatile thinner.
8. The improved process of forming waterproofing compositions. comprising the formation of a base of gilsonite and elaterite. soya bean oil. and China wood oil; and adding to said base, rock asbestos fiber, :1 vo'latile thinner, and a black pigment.
9. The process of forming a semi-liquid waterproofing composition of the character described. which consists in thoroughly mixing the following ingredients in approximately the proportions stated: gilsonite and elaterite seventeen parts, soya bean oil fourteen arts. China wood oil seven parts, asbestos her twenty-eight parts, volatile thinners thirty-three parts. and black pigment one part. L
In testimony whereof I have hereunto affixed my signature.
