Description

Sulfur Asphalt in Roofing, Damp-Proofing and Water Proofing Full description Background of the invention This application is a partial application of the original application No. 516370929 filed on 6 corresponding to 4/13/2016. The scope of the invention relates to asphalt installations for roof treatment; Isolation of moisture and water and its uses. More specifically; The field relates to asphalt, plastomer and sulfur-containing binders. During the manufacture and processing of asphalt-containing materials Jie asphalt-coated agglomerates and hot asphalt mixes; Working under temperatures above 300 degrees Fahrenheit may injure workers and damage their equipment. When the temperature exceeds 300 degrees Fahrenheit; We find sulfur and sulfur compounds found in asphalt or bitumen mixtures, including elemental sulfur, which represents inorganic compounds

0 isoatomic; It begins to react with the rest of the asphalt components and with the oxygen in the air. One of the main products of these reactions is hydrogen sulfide gas, where free sulfur in the hydrocrion media causes the dehydrogenation of hydrocriones to form hydrogen sulfide. Hydrogen sulfide is an irritant when present in low amounts, but becomes [IAT] with high amounts. In the form of hot sulfur when oxidized in the air sulfur oxide.

5 Sulfur oxide is a dang smelly air pollutant. It would work in high places; including boarding for metal roofing treatment; or in enclosed spaces, including basements and mines, to increase the chances of exposure to such non-foaming by-products and to aggravate their severity. It is desirable to find an asphalt formula that can be used under temperatures below 300 °C to ensure the safety and comfort of workers, as well as to avoid the release of unpleasant chemicals into the environment.

sulfur; Especially "free" or elemental sulfur; Bale is plentiful and low cost.

Elemental is a by-product of processing natural gas and non-sweet (sulphurous) petroleum. Include sulfur sources

All petroleum refining units and gas sweetening complex (desulphurization). Bly is the amount of sulfur

extracted annually from natural gas and petroleum processing; Many sulfur producers view elemental sulfur as SLE and others have attempted to use waste sulfur as an extender or filler

for asphalt and bitumen formulations, but with limited success. So it is desirable Lad

Finding commercial uses for elemental sulfur. The introduction of sulfur in commercial products would change the outlook

Much of it as waste into a product of practical value as a resource extension agent for hydrocarbons.

General description of the invention

0 A sulfur-containing asphalt-plastic binder formulation used in cola insulation, damp insulation and roof treatment applications includes elemental sulfur; Plastomer and asphalt binder. The sulfur-containing asphalt-plastic binder composition includes elemental sulfur at a ratio of about 710 to about 730, a plastomer at a ratio of about 73 to about 710, and an asphalt binder at a ratio of about 760 to about 787; each of the total weight.

5 includes a method for waterproofing or isolating moisture for a protected member having a surface treated with an asphalt binder composition and a plastomer containing sulfur on the step of combining a plastomer with an asphalt binder preserving the heat of mixing the plastomer so that an intermediate mixture of asphalt binder is formed. The method also includes the step of combining the elemental sulfur with the intermediate asphalt binder while maintaining the sulfur mixing temperature so that the sulfur-containing asphalt-plastic binder composition is formed. It includes asphalt binder composition

0 and plastomers containing elemental sulfur in a ratio ranging from about 710 to about 0 and plastomers in a ratio ranging from about 73 to about 710 asphalt binders with a ratio ranging from about 760 to about 787 each of the total weight. The method also includes the application of a sulfur-containing asphalt-plastic binder composition to the surface of the protected member so that the sulfur-containing asphalt-plastic binder composition touches the surface of the protected member and forms a layer

5 on its surface and stick to it. The asphalt binder formulation is applied at a temperature range of temperature

surrounding to a degree not exceeding 150 m. The layer formed prevents the movement of water through the protected member. The layer formed has one side Jf that touches and bonds to the surface of the protected member and a second side that does not touch the surface of the protected member. The formation of sulfur-containing asphalt-plastic binders would consume a significant amount of sulfur "waste" in an asphalt binder application at low temperatures. The sulfur-containing asphalt-plastic binder includes elemental sulfur in a proportion ranging from about 710 to about 0 by the total weight of the composition. in conventional plastomer/asphalt mixtures; Le We Asphalt replaces this ratio 710 to 730 of the material. Therefore, the use of sulfur covers the supply of asphalt with a cheaper and more available material that adds; Unexpectedly desirable properties of viscosity. In addition to this, the fittings meet ASTM requirements for certain types of roofing applications; And moisture insulation and waterproofing. And with the stability of the application temperature of the asphalt binder, the plastomer, and the sulfur-containing one in the range from the ambient temperature to not exceeding 150 m, we avoid the formation of hydrogen sulfide and sulfur oxides in the atmosphere surrounding workers and equipment; particularly in isolated and enclosed environments ie 5 building surfaces; ground floors; And the places that people cannot reach are general dag. The lower temperature when manufacturing and using sulfur-containing asphalt-plastic binders and lower viscosity lead to significant energy savings for the benefit of users.

The asphalt binder, plastomer and sulfur binder are made by combining asphalt binder, elemental sulfur and plastomer. The sulfur-containing asphalt-plastic binder is a combination of elemental sulfur in the range from about 710 to about 230, plastomer in the range from about 73 to about 710 and asphalt binder in the range from ss 760 to about 787; Each of them is from the total weight of the sulfur-containing asphalt binder and plastomer composition. A model of the sulfur-containing asphalt-plastic binder composition necessarily consists of elemental sulfur; Plastomers and asphalt binders. The sample composition necessarily consists of about 720 elemental sulfur »; about 75% of the plastomers and about 775% of the asphalt binder; Each of them is from the total weight of the sulfur-containing asphalt binder and plastomer composition. The form of composition 0 necessarily consists of about 730 elemental sulfur; Moa 75 plastomers and about 765 asphalt binders; JS of which is the total weight of the sulfur-containing asphalt binder and plastomer composition. Asphalt binder Bitumen and asphalt for use as an asphalt binder can be derived from petroleum distillation (eg, distillate tailings in hatchery media); canal treatments of sandy bitumen or oil shale; or from 5 Lindl natural sources (eg Lakes of Trebinidad). An asphalt primer may be a single material or a combination of several asphalt primers. Asphalt and bitumen are colloidal dispersions of asphaltic materials in the masticating phase. Asphaltic materials include large aromatic polycyclic molecule chains. asphaltic materials may include; Cyclo-alkanes, cyclo-alkenes, and alkane and alkene chains extend from polycyclic molecules of up to 30 0 (C30) creon atoms along their length. Asphaltic materials may also contain functional moieties capable of interacting with other materials. The functional moieties include alcohols; carboxylic acids; ketones phenols; amines; amides; sulfides; Sulfoxides 3 sulfonates ' sulfonic acids ¢ chelated porphyrin rings with vanadium (3 Jul) and iron.

The asphaltene materials also contain organic heterocyclic aromatic rings (eas) from their total polycyclic structure; Including benzothiophene, pyrrole and pyridine rings. It includes the maltene phase; which is more mobile compared to the asphaltene phase, asphalt resins, and non-polar aromatic substances; saturated cyclic hydrocarbons (lo) for example; naphthenate);

Both are straight and long-chain saturated hydrocriones. If it is not to be adhered to a particular theory; He finds that the aromatics in the malates phase tend to be the dispersing agent of asphaltoids; to interact with polar functional groups that may be present on asphaltene materials. The malates can be partially recovered from the dispersion using a 7-alkane-based solvent; While this is not possible with asphalt materials.

0 All types of asphalt and bitumen are suitable as asphalt binders. Asphaltene concentrate varies in quantity and function according to the bitumen source. (Sang) The asphaltene content of asphalt is typically in the range from about 70.1 by weight to about 730 by weight of matter. A sample sulfur-containing asphalt-plastic binder composition includes a 'performance-rated' binder according to the properties listed in the Performance Classification Table (Table 1). (For the specification of the classified asphalt binder

5 According to its performance M 320 AASHTO as an asphalt binder. It includes a model of the asphalt binder composition when the asphalt binder includes an asphalt binder 12-64 PG and it includes a model of the asphalt binder composition when the asphalt binder necessarily consists of pure PG 64-12 asphalt binder. Elemental sulfur Elemental or "free" sulfur includes not only individual sulfur atoms but also sulfur in compounds

0 complex and Wali) is covalently bonded to other sulfur atoms; Among them are alpha-sulfur (rhombic straight sulfur); Beta-sulfur (monocytic sulfur) and "chain-shaped" sulfur. Chains or rings of sulfur atoms can range from a limited number of cup atoms to hundreds of sulfur atoms held together by covalent bonds. All chemical forms of elemental sulfur are suitable for use in a sulfur-containing formulation. Sulfur is not considered to be covalently bonded to atoms other than sulfur; like Creon;

hydrogen or other types of atoms; including heterocyclic compounds; As a "free" or racist kennel. In view of the wide variety of chemical forms; Elemental sulfur has been found in many different forms, including solid and liquid, and can change between forms depending on the modifications that occur in its environment. These include heat and pressure. while ′′ treats; haa, either in solid form in the form of pellets or powder, or in the form of a melted liquid.

The source of elemental sulfur may be of natural origin (Jie) extracted) or from natural gas or petroleum processing processes. For example; Hydrogen sulphide is converted to elemental sulfur in the Claus unit in well-understood natural gas desulphurization processes.

0 Plastomers Plastomers occupy a position between polyolefins and conventional elastomers. Plastomers are a class of polymers when a load is applied to them, they succumb and expand (without easy crumbling cracks like conventional polyolefin Jie irregular polypropylene) and remain in their elongated position when the load is lifted (unlike elastomerics. Plastomers also typically add stiffness under high temperatures to model

Polyolefin », where elastomeric plastics begin to flow at lower temperatures. Plastomers can mitigate the potential for permanent deformation and loss of cohesion over long-term exposure to high temperatures; Such as on a fixture on the tops of ceilings and near heat radiators. Plastomers are thermoplastic by nature; Therefore, it deforms and changes its shape by plasticization or viscosity at the melting temperatures of the plastomer, and it becomes solid and stiff at temperatures below

fusion. Examples of useful plastomers are long-chain branched polyolefins; including Low Density Polyethylene (LDPE) polyolefins with multiple strands; Including Linear Low Density Polyethylene (1005A); ethylene/alpha-olefins copolymers / tertiary copolymers / tetrapolymers and alpha-propylene / olefin copolymers / tertiary polymers / diel polymers) where they include

alpha-olefins One or more C3 to C20 olefins among which is propylene; biotin; hexane; and octane” and including ethylene/brodylene at least 750 wt copolymers/tripolymers/polymers dae lll, ethylene butyl acrylate ¢ (EBA) and ethylene vinyl acetate (EVA) asphalt binder, plastomer and sulfur-containing formulations as an example The plastomer represented by the polymer Ethylene Vinyl Acetate (EVA) from the models of the asphalt binder and the plastomer containing sulfur is a model in which the plastomer necessarily consists of the polymer Ethylene Vinyl Acetate (EVA) Jods Examples of the useful EVA plastomers for the asphalt binder, the plastomer and the sulfur-containing on EVA and HSMP homopolymers as described in calla PCT publication No. 120482/2010 (Hussein, et al.) under

0 heading "Sulfur-containing polymer for use in asphalt binder and road maintenance". Among the sulfur-containing asphalt binder and plastomer composition models is one in which the plastomer is a homogeneous sulfur-modified polymer (HSMP) and one of the sulfur-containing asphalt binder and plastomer composition models is a model in which the plastomer necessarily consists of a sulfur-modified homogeneous polymer (HSMP)

5 Formation of asphalt binder and sulfur-containing plastomer The components of asphalt binder and sulfur-containing plastomer may be added and mixed in any order. A non-exhaustive example is the addition of individual components to a preheated and stirred asphalt binder. (Sarg) Addition of other components to form the asphalt binder, plastomer and sulfur-containing sequentially or simultaneously.

Mixing is done in a suitable container or apparatus to bring together all the asphalt binder, plastomer and sulfur-containing components. Suitable utensils and appliances include metal containers with hand mixers; reactors; Hoppers, mixing bowls, tanks, and high or low shear mixing dallas. Mixing device works to keep both asphalt base sale; And intermediate composition and asphalt binder and plastomer and sulfur-containing at a constant temperature greater than ambient conditions as well as mixing

ingredients until homogeneity is reached. Maintaining a high and constant temperature would ensure that the possibility of formation of hydrogen sulfide and sulfur dioxide is reduced; Which potentially harms those mixing people” when adding sulfur to the formulation or forming the sulfur-containing asphalt binder and plastomer. The mixing device creates a circular motion in the molten asphalt binder and keeps any intermediate mixtures in molten form to ensure amalgamation.

Complete asphalt binder components. The process for modeling the sulfur-containing asphalt binder and plastomer composition includes introducing into the appropriate mixing device the asphalt binder used as the base material and then heating the asphalt binder to the mixing temperature of the plastomer. The plastomer mixing temperature is greater than 150 °C and is mostly maintained

0 where the asphalt substrate melts and becomes fluid; But do not exceed this. in some cases; The sale of asphalt substrate is heated to a plastomer mixing temperature of about 180 °C. The plastomer is introduced into the asphalt binder and mixed at the plastomer mixing temperature until it is completely contained to form an intermediate asphalt binder mixture. The plastomer mixing temperature is relatively low compared to typical hot-mix applications. Heat is applied for the time required for the plastomer to combine with the binder

5 asphalt. The risk index for the formation of hydrogen sulfide and sulfur dioxide is reduced as long as the Sale asphalt substrate does not contain a significant amount of free sulfur. Upon complete inclusion of the plastomer, the temperature of the intermediate asphalt binder mixture is cooled to the mixing temperature of sulfate. The heat of mixing of sulfur shall be in the range from about the melting point of elemental sulfur to not exceeding ef the flash point of the asphalt binder, plastomer, sulfur containing or

0 about 150m; Depending on the elemental sulfur content. And according to the shape of the free sulfur particles, the melting point of sulfur varies between about 120 and about 140 m. Upon reaching the heat of mixing sulfur; Elemental sulfur is introduced into the intermediate asphalt binder mixture and mixed with it for a sufficient period of time until it is completely contained. Asphalt binder, plastomer, and sulfur-containing binder are formed immediately after sulfur is contained.

The sulfur-containing asphalt-plastic binder is stable in its composition. The sulfur-containing asphalt and plastomer binder can be maintained at el of ambient temperature but not to exceed 150°C for extended periods for both indoor and outdoor applications. Use of asphalt binder, plastomer and sulfur-containing

Under the method of waterproofing or damp proofing; A sample of asphalt binder, plastomer, and sulfur-containing is applied to the surface of a protected member to form a water-repellent or moisture-repellent layer. The layer formed shall have a first side that contacts and adheres to the surface of the protected member and a second side that does not touch the surface of the protected member. The layer adheres to the surface of the protected member and prevents water from moving through the protected member. It is preferable that the surface be Elias, but not necessarily. He is

0 asphalt binder and sulfur-containing plastomer is particularly suitable for roof top treatment and roofing treatment materials already in use. Asphalt binder and sulfur-containing plastomer are used as primers for other coatings; for roofing treatment, moisture insulation and waterproofing; including affixing of roofing sheets to roofing or waterproofing coverings for roofing assemblies, pipe coating spraying and other industrial protection systems; Among them is steel

5 and iron. In one of the models of the method; A second material is inserted on the second side of the layer so that the layer is attached to the second material. The temperature of the layer ranges from about ambient temperature to not exceeding 140 °C. The sulfur-containing asphalt binder is applied to hall ceilings and other surfaces using asphalt binder spreading and spraying equipment known to those skilled in the art.

0 and we find the adhesion of the asphalt binder and the sulfur-containing plastomer to the surfaces. especially metal surfaces; superior to conventional pure asphalt; enables it to adhere not only to surfaces but to materials placed on it while the formula is higher than the ambient temperature; ceiling tiles included; crushed stone and agglomerates; bitumen and wax paper; Fabrics and other materials supporting Jie's water, moisture insulation and roofing activities.

The asphalt binder for all embodiment examples is pure clin 64-10 rated PG 5 and the plastomer used for all example formulations comprising it is HSMP150 manufactured according to the procedures set forth in Publication 007 of International Patent Application No. 120482/2010 (Hussein, et al.) for a written description of the published request. “15]/0150]” is a product that combines as described in the published order 750 wt. of elemental sulfur 5 750 wt. of EVA-28-0. The EVA copolymer features 728 wt. and melt flow coefficient 150 g/10 min Before forming the HSMP150 product the asphalt binder is heated to a mixing temperature greater than 150 C. When sulfur and plastomer are part of the same experimental formulation, pure asphalt is mixed with the plastomer at 140 C by means of a blade mixer ad high and mixing speed 2500 dal per minute to form an intermediate composition Elemental sulfur is introduced into the intermediate composition and mixed with it until deans on a homogeneous composition In formulations when the plastomer is not part of the formulation, the asphalt binder is heated to a temperature of about 160 m For all experimental formulations a mixer fitted with a high shear mixing blade mixes each component separately for about 5 minutes for homogenization Each of the experimental formulations formed (asphalt binders Ala ¢ asphalt binders 0 plastomer-containing » And asphalt binders containing Plast myrrh and sulfur) at a temperature in the range from about 135 C to about 145 C for practical application and experimentation. Each of the formulations listed in Table 1 has a total weight of the formulation. For example; The proportion of "7107+ plastomers" is a composition of 710 of which is a plastomer and 790 of which is a regular or pure asphalt binder; Each component of the total weight of the formulation.

Table 1: Several properties of pure asphalt binder, asphalt binder with plastomer ratio 710-5 plastomer, and several sulfur/plastomer asphalt binders with varying amounts of plastomer and sulfur. As shown in Figure 1) the plastomer/sulfur/asphalt composition appears in the proportions of 75/20/5

751.7 decrease in viscosity versus a 95/5 plastomer/asphalt mixture and a 736.5 decrease in viscosity versus pure asphalt. The 5 ratio plastomer/sulfur/asphalt combination shows a 753.3 decrease in viscosity versus the 95/5 ratio plastomer/asphalt combination and a 738.7 decrease in viscosity versus the pure asphalt. We find an improvement in viscosity that is superior to both conventional plastomer/asphalt formulations, and pure asphalt binder allows the application of

0 Plastum R/Sulfur/Asphalt formulations with a relatively low energy requirement; It reduces mixing time and improves the ease of application over conventional asphalt equipment. Table 1 shows that the 75/20/5 and 65/30/5 plastomer/sulfur/asphalt formulations have penetration values and softening points similar to the pure asphalt/plastic/asphalt formulations. Plastomer/sulfur/asphalt formulations with ratios of 75/20/5 and 65/30/5 score similar improvements from Cun 5 ductility and malleability values over pure asphalt formulations such as plastomer/asphalt formulations. With plastomer/asphalt formulations reporting similar penetration values; This allows dallas to similarly treat plastomer/sulfur/asphalt formulations with similar softening points, ductility and ductility when applied and maintained.
