Description

“A composition for an intumescent paint”
Field of the invention
[0001] The present invention relates to a composition for an intumescent paint. More particularly, the present invention relates to an intumescent paint that protects a substrate against the effects of high temperatures and flames.
Background of the invention
[0002] Generally, woods and steel are the major components used in the construction of any building to bear the load against heat, rain pollution, etc. There are many products (paints and water-based solutions) available in the market which protects wood and steel, however, these products do not protect the wood and steel against high temperatures, heat, fire, and the like. Also, the application cost of products is very high. Further, the raw material used in these products is very difficult to find and manufacture.
[0003] Furthermore, the products that are available in the market do not provide proper insulation to the surface to protect against the collapse of structures (roofs, beams fabrication structures, etc). [0004] Till today, there is no such product or paint available which protects the wood and steel against high temperatures, heat, fire, and the like.
[0005] Therefore, there is a need for such products or paints which can overcome the drawbacks of the existing way of manufacturing cement.
Objects of the invention
[0006] Object of the present invention is to provide a composition for an intumescent paint.
[0007] Another object of the present invention is to provide a composition for an intumescent paint, which provides proper protection to the wood and steel against high temperatures, heat, and fire.
[0008] Yet another object of the present invention is to provide a composition for an intumescent paint, which prevents the structure from collapsing due to loss in strength of the material of the building.
[0009] Another one object of the present invention is to provide a composition for an intumescent paint, which is simple and economical in operation. Summary of the invention
[0010] According to the present invention, there is provided a composition for an intumescent paint. The composition includes an anatase titanium dioxide (TiO2) range from 1 kg to 10 kg by weight, a rutile titanium dioxide (TiO2) ranges from 1 kg to 10 kg by weight, a barytes ranges from 1 kg to 10 kg by weight, a biocides ranges from 200gm to300gm by weight, a PVC latex emulsion ranges from 15kg to 25kg by weight, a monophosphate ranges from 30kg to 40kg by weight, a diphosphate ranges from 30kg to 40kg by weight, a distilled water ranges from 10kg to 20kg by weight, a pentaerythritol phosphate ranges from 10kg to 20kg by weight, a clear lacquer ranges from 5kg to 15kg by weight, and a thickener ranges from 150gm to 250gm. The composition is mixed in water and stirred to form the intumescent paint. Specifically, in the present embodiment, upon exposure to heat, the coating of the composition swells resulting in decreased density and increased volume on the surface to produce a carbonaceous char. The carbonaceous char acts as an insulating layer to protect the substrate. The carbonaceous char is formed due to microbubbles on the exposed surface.
Detailed description of the invention
[0011] An embodiment of this invention, illustrating its features, will now be described in detail. The words "comprising," "having," "containing," and "including," and other forms thereof, are intended to be equivalent in meaning and be open-ended in that an item or items following any one of these words is not meant to be an exhaustive listing of such item or items, or meant to be limited to only the listed item or items.
[0012] The terms “first,” “second,” and the like, herein do not denote any order, quantity, or importance, but rather are used to distinguish one element from another, and the terms “a” and “an” herein do not denote a limitation of quantity, but rather denote the presence of at least one of the referenced items.
[0013] The present invention provides a composition for an intumescent paint. Also, the composition provides proper protection to the wood and steel against high temperatures, heat, and fire. Further, the composition prevents the structure from collapsing due to the loss in strength of the material of the building. Furthermore, the composition is simple and economical in operation.
[0014] Referring to the present invention, a composition (100) for an intumescent paint in accordance with the present invention is illustrated. The composition (100) includes an anatase titanium dioxide (TiO2) range from 1 kg to 10 kg by weight, a rutile titanium dioxide (TiO2) ranges from 1 kg to 10 kg by weight, a barytes ranges from 1 kg to 10 kg by weight, a biocides ranges from 200gm to300gm by weight, a PVC latex emulsion ranges from 15kg to 25kg by weight, a monophosphate ranges from 30kg to 40kg by weight, a diphosphate ranges from 30kg to 40kg by weight, a distilled water ranges from 10kg to 20kg by weight, a pentaerythritol phosphate ranges from 10kg to 20kg by weight, a clear lacquer ranges from 5kg to 15kg by weight, and a thickener ranges from 150gm to 250gm. Specifically, in the present embodiment, the anatase titanium dioxide (TiO2) 5 kg by weight, the rutile titanium dioxide (TiO2) 6 kg by weight, the barytes 5kg by weight, the biocides in the range of 200gm-300gm by weight, the PVC latex emulsion 20kg by weight, the monophosphate 32 kg by weight, the diphosphate 32 kg by weight, the distilled water 12 kg by weight, the pentaerythritol phosphate 11kg by weight, the clear lacquer 10kg by weight, and the thickener 200gm. The composition (100) is mixed in water and stirred to form the intumescent paint. Specifically, upon exposure to the heat, the coating of the composition 100 swells which results in the decreased density and the increased volume of the exposed surface to produce a carbonaceous char. In the present embodiment, upon exposure to the heat, the coatings retard the spread of fire due to the formation of a microbubble when applied on wood or any other combustible surface. Also, the carbonaceous char is formed due to the microbubbles on the exposed surface. In the present embodiment, the carbonaceous char acts as an insulating layer to protect the substrate.
[0015] Further, in the present embodiment, a washable two topcoat is used as a protection against environmental degradation or for decorative purposes. Mostly, the intumescent paints require the use of a chemical combination of a polyol, or ammonium phosphate, and an amide. In fire retardant, intumescent paints, polyvinyl acetate, polyvinyl chloride, and acrylic lattices are used. The latex is stable in the presence of soluble inorganic salts. As the intumescent paints are hydroscopic, the flexibility of the film varies with atmospheric humidity. Also, the continued exposure to an atmosphere having high humidity reduces the intumescing property of the paint film.
[0016] Furthermore, the coating prevents the structure from collapsing due to the loss of strength of the material of the building. For example, for steel, the critical state is linked to the critical temperature which is defined as the temperature at which the load-bearing capacity becomes equal to the effect of the applied loads (steel element is very close to collapse). Hence, the coating is required to prevent the structure from collapsing due to the loss of strength of the material. For concrete, the critical state is linked to the critical temperature of the reinforcing bars (normally from 350 °C to 500 °C) and to reach a temperature of 500 °C inside the concrete element. For wood, the critical state is linked to the residual section of the timber load-bearing element after burning.
[0017] Therefore, the present invention provides the advantage of composition (100) for an intumescent paint. Also, the composition (100) provides proper protection to the wood and steel against high temperatures, heat, and fire. Further, the composition (100) prevents the structure from collapsing due to the loss in strength of the material of the building. Furthermore, the composition (100) is simple and economical in operation. [0018] The foregoing descriptions of specific embodiments of the present invention have been presented for purposes of illustration and description. They are not intended to be exhaustive or to limit the present invention to the precise forms disclosed, and obviously many modifications and variations are possible in light of the above teaching. The embodiments were chosen and described to best explain the principles of the present invention and its practical application, to thereby enable others skilled in the art to best utilize the present invention and various embodiments with various modifications as are suited to the particular use contemplated. It is understood that various omission and substitutions of equivalents are contemplated as circumstance may suggest or render expedient, but such are intended to cover the application or implementation without departing from the spirit or scope of the claims of the present invention.
