Description

  The present invention relates to detection. More particularly, the present invention relates to paints for detecting corrosion, chemicals, and radioactive materials.

  Corrosion damage is often hidden under a protective paint coating. Corrosion has been reported to hit 35,000 ground vehicles and combat vehicles, 15000 fighters and helicopters, 1000 combat missiles, and 300 warships with approximately 34.5 million square meters. Such degradation includes mechanical destruction of combat vehicles, warships on the verge of sinking, crashing of multiple combat jets in the 1980s, and landing of multiple naval jets during operational operations on aircraft carriers. It is thought to be the cause of the destruction of the device. Corrosion maintenance activities involve US Department of Defense staff of approximately 70,000 military personnel and civilians, and thousands of private companies worldwide. The US Department of Defense pays $ 10-20 billion annually for corrosion damage. In 1998, helicopter corrosion repair alone cost about US $ 4 billion. If problems are found early, repair costs will be reduced.

The paint / coating of the present invention allows chemical and radioactive weapons to be detected visually, either directly or using equipment. Such paints and coatings can warn soldiers that have undergone chemical and radioactive invasion. This feature may be added to the combat vehicle during maintenance actions. Using paint inside buildings, trains, and subway tunnels provides a means to detect the presence of chemical and radioactive weapons over a large area. Nerve gas is an organophosphorus compound that strongly suppresses cholinesterase. Signs of muscarinic and nicotinic overstimulation include abdominal pain, vomiting, diarrhea, excessive salivation and sweating, bronchospasm, massive pulmonary secretion, muscle cramps and weakness, and respiratory arrest. There may also be seizures, bradycardia, or tachycardia. Severe dehydration can result from water loss due to sweating, vomiting, and diarrhea. Sequelae include polyneuropathy and neuropsychiatric changes.

It should be noted that the present invention is not limited to the specific embodiments disclosed. The present invention covers all modifications, equivalents, and alternatives that are within the spirit and scope of the invention as defined by the appended claims.

  The accompanying drawings, which form a part of the specification, illustrate specific embodiments of the invention. The detailed description of the specific embodiments, together with the general description of the invention, serves to explain the principles of the invention.

  Referring to the figures, the following detailed description, and the materials contained therein, detailed information about the present invention is provided, including descriptions of specific examples. The detailed description serves to explain the principles of the invention. The present invention can tolerate modifications and variations. The present invention covers all modifications, equivalents, and alternatives that are within the spirit and scope of the invention as defined by the appended claims.

  Referring to FIG. 1, an embodiment of the system of the present invention is illustrated. This embodiment of the system is designated generally by the reference numeral 100. The system 100 warns of cracks on the structure 101 due to corrosion or external influences. Cracks due to corrosion or external influences are illustrated by irregular shaded areas 105. The system 100 for warning of cracks due to corrosion or external influences comprises the steps of painting the surface 102 to be examined with the indicating paint 103 and observing the paint 103 suggesting cracks 105 due to corrosion or external influences. The paint 103 includes the substance 104, suggesting a crack 105 due to corrosion or external influences. For example, the paint 103 may suggest a crack 105 due to corrosion or external influences by changing color.

  Warning of structural 101 corrosion or cracks due to external influences can be very useful and can provide significant advantages. Corrosion has been reported to hit 35,000 ground vehicles and combat vehicles, 15000 fighters and helicopters, 1000 combat missiles, and 300 warships with approximately 34.5 million square meters. Such degradation includes mechanical destruction of combat vehicles, warships on the verge of sinking, crashing of multiple combat jets in the 1980s, and landing of multiple naval jets during operational operations on aircraft carriers. It is thought to be the cause of the destruction of the device. Corrosion maintenance activities involve US Department of Defense staff of approximately 70,000 military personnel and civilians, and thousands of private companies worldwide. The US Department of Defense pays $ 10-20 billion annually for corrosion damage. In 1998, helicopter corrosion repair alone cost about US $ 4 billion. If problems are found early, repair costs will be reduced.

  The sensing coating of system 100 can reveal substrate damage during visual inspection using an auxiliary device. Corrosion can be detected by chemically sensitive fluorescent / colorimetric additives. Cracks due to external influences can be detected by a strain sensitive coating. A safe radioactive tracer can be used to track important metal losses. Some of the paints and coatings of the present invention make it possible to visually detect damage due to corrosion and external influences, either directly or using an apparatus. Such coatings warn pilots, navigators, and soldiers of imminent failures early through visual inspection. For example, this feature may be added to the surface during maintenance at a daily terminal. This feature may also be added to the ship and submarine when the ship and submarine are in a port or when working on a dry dock.

  Corrosion damage, such as crack 105 due to corrosion or external influences, for example as illustrated in FIG. 1, is often hidden under the protective coating. Electronic corrosion sensors are unreliable, expensive and difficult to install. Corrosion present under the coating is accompanied by a detectable chemical change. A detectable chemical change is, for example, a decrease in pH caused by hydrolysis of a molten polyvalent metal cation. The present invention provides a chemically sensitive coating 103. The coating 103 may be applied during normal maintenance and can be used as an early indication of corrosion.

  In addition to detecting pH changes, a wide variety of other functions can be utilized to detect corrosion damage. The paint 103 system is roughly classified into three types. It suggests (1) chemically sensitive additives added to the coating, including pH sensitive indications, (2) strain sensitive coatings, and (3) significant loss / migration of metals A radioactive tracer, with the ability. The substance 104 included in the paint 103 illustrated in FIG. 1 may be one or more of the following additives. It consists of fluorescent molecules and particles (which are sensitive to pH and chloride), semiconductor clusters inside the zeolite cage (screening based on molecular size), electroactive redox couples (electrochemical potential and oxidation state) Sensitive), conductive polymer networks (sensitive to local potentials and currents due to corrosion), materials with anisotropic dielectric (optical and electrical) properties (sensitive to stress and strain), various radioactive isotopes Elemental tracers (sensitive to metal dissolution and migration), and thermoluminescent and photoluminescent dyes (sensitive to dissolved metal migration) that image the movement of radioisotope tracers.

  An example of a safe radioisotope tracer that suggests metal loss is Tc-99. Tc-99 releases beta particles during decay. This material may be ion implanted onto the surface of critical structural components such as aircraft spar and lap joints. Crack erosion causes dissolution of the surface with ion-implanted Tc-99. Such dissolution makes it possible to detect the movement of the ion-implanted radioactive tracer. Thereby, the loss of metal is clearly shown. The degree of metal loss correlates with the intensity of scintillation associated with β decay. Other radioisotope tracers can also be used. Other radioisotope tracers include those that emit gamma rays. Specifically, the warning of crack 105 due to corrosion or external influences on structure 101 is realized by putting organic scintillation material 104 into coating 103. The coating 103 containing the organic scintillation material 104 has the ability to generate luminescence from the injected Tc-99 when irradiated with beta rays. The dissolution and migration of the base metal can be imaged by the coating 103.

  Applicants have tested embodiments of the present invention that include the “intelligent coating” or “smart surface” illustrated in FIG. “Intelligent coatings” or “smart surfaces” make it possible to detect even small changes in pH at the coating-substrate interface, indicating crevice corrosion. Applicants measured the pH at the tear. The results showed that the pH was strongly acidic and the change could be easily detected. Such pH measurements were made with a fiber optic probe having a fluorescent dye deposited on the chip. A ratiometric measurement of the fluorescence peak is believed to represent pH. In “intelligent coating”, a pH sensitive substance is put directly into the coating 103. Other specific coatings are developed for chemical weapon detection. Still other specific coatings require pH sensitivity that “should be in place” to allow detection of corinosterase inhibitors.

  Referring to FIG. 2, another embodiment of the system of the present invention is illustrated. This embodiment of the system is designated generally by the reference numeral 200. The system 200 warns of chemical or radioactive weapons. The chemical or radioactive weapon warning system 200 includes the steps of painting the surface 202 of the structure 201 that is to be examined with the indicating paint 203 and observing the paint 203 suggesting a chemical or radioactive weapon.

  The paint 203 contains a substance, suggesting a chemical weapon or a radioactive weapon. In the detection of chemical weapons (CWA), alkyloxymethyl phosphonate contained in the paint 203 reacts with an appropriate dehydrating agent to generate a corinosterase inhibitor. Subsequently, the corinosterase inhibitor is detected by a color-developing suggestive molecule sensitive to pH. The chemical weapon (CWA) is illustrated by the CWA cloud 208.

  Referring again to FIG. 2, the detection of chemical weapons (CWA) by paint 203 is described in considerable detail. For example, CWA208 may contain nerve gases that are organophosphorus compounds that are potent corinosterase inhibitors. Signs of muscarinic and nicotinic hyperstimulation include abdominal pain, vomiting, diarrhea, excessive salivation and sweating, bronchospasm, massive pulmonary secretion, muscle cramps and weakness, and respiratory arrest. There may also be seizures, bradycardia, or tachycardia. Severe dehydration can result from water loss due to sweating, vomiting, and diarrhea. Sequelae include polyneuropathy and neuropsychiatric changes.

  The system 200 enables detection of CWA 208 by chemically sensitizing the paint or coating 203. Patent documents 3 and 4 describe alkyloxymethyl phosphonates that react with a suitable dehydrating agent to produce a corinosterase inhibitor.

  Included as reagents used in the system 200 are (1) methylphosphonic acid (MPA) and methylphosphonic acid alkyloxy (AMPA), MPA ethyl (EMPA), MPA isopropyl (IMPA), MPA cyclohexyl (CMPA), MPA pinacolyl. (PMPA), O-ethyl methylphosphonate (EMPTA), and 1,4-dithiane (DITHIANE), (2) esterification reagents, dialkyl sulfates, and dialkyl iodides, (3) dehydration and other reagents, 1 , 3-Dichlorohexylcarbodiimide and 1,3-diisopropylcarbodiimide, (4) Reagent for chromogenic detector, bromocresol green, 7,7,8,8-tetracyanoquinodimethane (TCQN), and NaOH And (5) solid adsorbent, alumina, and silica.

  Subsequently, the corynesterase inhibitor produced by reacting AMPA with an appropriate dehydrating agent is detected by a color-developing suggestive molecule sensitive to pH. Bromcresol green is a general coloring suggestive substance. Bromcresol green is blue at pH ≧ 5.4 and yellow at 3.8 <pH <5.4. The presence of a corynesterase inhibitor on the surface of the solid adsorbent reduces the pH from a value greater than 5.4 to an acidic level of 3.8 to 5.4. This causes a color change.

  The chemical weapon detection system 200 utilizes esterification reagents and dehydrating agents included to maintain the activity of the esterification reagents and dehydrating agents. This includes incorporating functionality directly into the polymer coating, triggering the release of the reagent from the capsule, and release in a transport limited time.

Detection of radioactive weapons (RWA) uses a scintillation agent included in paint 203. A radioactive weapon (RWA) is illustrated by arrow 204. Special crystalline dyes 205, 206, and 207 are added to paint 203. The paint 203 emits light λ ₁ , λ ₂ , and λ ₃ when irradiated with α rays, β rays, and γ rays 204. These scintillations may be detected directly by a photomultiplier tube (PMT), digital CCD array camera, or other such device coupled with an amplifier and pulse measurement electronics. Alternatively, scintillation may be used to stimulate the phosphors in the dye contained within the paint polymer binder. The α scintillation dye 205 emits light λ ₁ . The β scintillation dye 206 emits light λ ₂ . The γ scintillation dye 207 emits light λ ₃ .

Referring again to FIG. 2, detection of radioactive weapons (RWA) with paint 203 is described in considerable detail. For example, radioactive weapons are detected by scintillation. Crystalline dyes 205, 206, and 207 are added to paint 203. The paint 203 emits light λ ₁ , λ ₂ , and λ ₃ when irradiated with α rays, β rays, and γ rays 204. The luminescence may be detected directly by a PMT, digital CCD array camera, or other such device. Alternatively, the luminescence can be used to stimulate fluorescence in a dye contained within the polymer binder of the paint. The fluorescence is detected as a secondary emission. Some of the components used in system 200 are: For example, (1) LiI (Sn) for neutron detection, ZnS (Ag) for alpha particle detection, NaI (Tl) for gamma ray detection, CsI (Tl) for gamma ray detection, for gamma ray detection Inorganic scintillators such as CsI (Na), BGO for γ-ray detection, and BaF ₂ for γ-ray detection, and (2) anthracene, for example for β-ray and neutron detection, trans-stilbene for β-ray detection, Organic scintillators such as p-terphenyl for β-ray detection, diphenylorazole for β-ray and neutron detection, tetraphenylbutadiene for β-ray detection, and terphenyl in polystyrene for β-ray detection. These are included in the paint 203 and have RWA sensitivity. Note that other active agents may be utilized.

  Applicants have shown that the radiation sensitive coating according to the invention illustrated in FIG. 2 has been successful. This was achieved by successfully detecting scintillation from the painted surface irradiated by both alpha particles and gamma rays. Alpha particles from weak 1-nCi plutonium 239 were detected by a special scintillation paint, a photomultiplier tube (PMT), and an appropriate pulse measurement network. A parametric investigation is performed to determine the coating thickness and the scintillation rate as a function of the spacing between the coating and the radiation source. The optimal paint thickness is specified in this scenario. The paint must be thick enough to provide a level at which scintillation can be easily detected, but the scintillation should be thick enough to cause self-absorption by the paint before reaching the detector. I knew it wouldn't be. Γ-rays from a 100-μCi radium 226 source were also detected by other special scintillation coatings and by taking a time-lapse photograph with a commercially available 12.8 million pixel camera.

  The coating represented by the systems 100 and 200 illustrated in FIGS. 1 and 2 may be applied using a variety of application methods. For example, there are numerous methods for the manufacture of derivative paints and coatings that detect the presence of radioactive weapons on or near the surface, and for the production of “integrated” paints and coatings that quantify prolonged exposure to large amounts of radiation. May be used. These coatings contain scintillation and / or thermoluminescent materials as pigments. These coatings can also be easily manufactured by various processes. Such processes include organic polymer binders, paints or coatings sprayed with organic polymer binders, paints or coatings applied with brushes with organic polymer binders, web coaters and coatings produced with organic polymer binders. And membranes, powder coatings, ceramic / metal binders that are inorganic, low temperature spray processes, and high temperature spray processes.

  Paints and coatings may be signaled by any one of a number of systems. These include (1) alpha rays, beta rays or gamma rays from pigment particles by PMT, digital CCD array cameras, or other such devices in combination with amplifiers and pulse measurement electronics for derivative coatings. Simultaneous detection of induced scintillation, and (2) laser pulses, filaments, or local microwave heating that induce emission of photons from irradiated thermoluminescent dye particles for the integrated coating, followed by emitted photons Includes, but is not limited to, laser pulses, filaments, or local microwave heating, detected by a PMT, digital CCD array camera, or other such device coupled with amplifiers and pulse metrology electronics Do not mean. A PMT, digital CCD array camera, or other such device, coupled with amplifiers and pulse measurement electronics, integrates the dose at the exposure time and provides a signal proportional to the dose.

  For detection of radioactive material, the present invention represented by the systems 100 and 200 illustrated in FIGS. 1 and 2 has many applications. For example, radiation sensitive paints and coatings can be used to observe exposure in various scenarios of interest. The various scenarios of interest are: (1) painting of buildings and equipment in industrial plants involved during the production of nuclear and radioactive materials, (2) painting inside nuclear power plants, nuclear ships, and nuclear submarines, (3) Painting of trucks and shipping containers, and painting of roadside facilities along the route of transport, (4) Painting of unmanned aerial vehicles, micro airships, and other reconnaissance equipment, and (5) activity containing radioactive materials It is the coating which detects and observes. In addition to the observed nuclear power generation and the ability to receive long-term exposure (irradiation) on the ship, these coated surfaces track the extent of radioactive contamination and It can be used for imaging. Ultimately, thermoluminescent coatings and coatings can be used as a basis to prove that the shipping container has been accepted by the United States. Such proof may be done by area inspection of the paint surface or by inspection of the collected paint chips.

  These coatings also reduce the corrosion damage present under the protective coating by allowing unexpected movement of ion implanted tracers (such as Tc-99) to be detected and observed on aircraft. It may be used to detect.
