Description

Technical Field

[0001] The invention relates to the technical field of termite trapping, and in particular to a conductive material for attracting termites, a preparation method and a termite trapping device comprising the material. Background Art

[0002] Conductive materials are a class of materials with good electrical conductivity, which are widely used in electronic devices, energy storage and conversion, sensors and other fields. At present, many important advances have been made in the development of conductive materials, including metal conductors, conductive polymers, carbon-based materials, etc. Metal conductors are one of the most traditional and common conductive materials. However, metal conductors have disadvantages such as heavy weight and poor flexibility, and may not be flexible enough in some applications; carbon-based materials such as graphene, carbon nanotubes, graphene oxide, etc. have attracted much attention due to their excellent conductive properties, but the preparation cost of carbon-based materials is high, and there is still the problem of unstable conductive properties in some applications; conductive polymers have great potential in the fields of flexible electronic devices and flexible sensors due to their lightweight, flexibility and plasticity. Conductive polymers such as polyaniline, polythiophene, and polystyrene perform well in microelectronic devices. However, the conductivity and sensitivity of conductive polymers are still inferior to those of metal or carbon-based materials, and further improvement is needed.

[0003] "A thousand-mile dam collapses because of ant holes". Termites often build nests and ant tunnels inside water conservancy dams, which can easily cause leakage and even collapse in serious cases. It is a major hidden danger that endangers the safety of water conservancy projects. According to incomplete statistics, there are more than 500 reservoirs in the country that have collapsed due to termite damage. In recent years, with the warming of the climate, the scope of termites' activities and the degree of damage have shown an increasing trend. Termite damage has been found in large areas of water conservancy projects in 18 provinces (municipalities and autonomous regions), including Jiangsu, Zhejiang, Anhui, and Henan. Therefore, strengthening and standardizing termite prevention and control has become an urgent and important task that affects the safety of water conservancy projects.

[0004] The method used to kill termites is usually to place termite-killing drugs in multiple places, but there are many problems, such as: short effectiveness, easy to become ineffective due to rain, unreasonable placement, low termite density, certain pollution to the environment, inability to achieve centralized killing of termites, and inability to kill termites fundamentally. In response to the above problems, many companies have developed termite trapping devices. Although the termite trapping devices currently on the market can prolong the effectiveness of termite drugs, the product device cost is too high, the structure is complex, the size is large, and the use is time-consuming and labor-intensive. More importantly, the termite trapping device still needs to be manually monitored, inspected, and maintained. The above-mentioned traditional termite trapping monitoring device lacks the function of intelligent data collection, which makes it impossible for users to view it in real time, thereby reducing the use effect. Summary of the invention

[0005] Purpose of the invention: The purpose of the present invention is to provide a conductive material with excellent conductivity and sensitivity, which can attract termites to gnaw on it; and apply it to a termite trapping device. Termites gnawing on the conductive material will cause fluctuations in the current, and the current signal is captured and transmitted to the cloud, and information is obtained through a monitoring platform, eliminating the need for manual real-time monitoring and maintenance of the trapping device.

[0006] The technical solution of the present invention:

[0007] In one aspect of the present invention, a conductive material for attracting termites is provided. The raw materials of the conductive material include at least 50-90 parts of a composite conductive resin, 20-30 parts of graphene intercalated lignin and 30-50 parts of a solvent, calculated by weight.

[0008] In some embodiments, the conductive material further includes an auxiliary agent, which includes but is not limited to one or more combinations of an antioxidant, a dispersant, a toughening agent, a defoaming agent, and a silane coupling agent.

[0009] In some embodiments, the method for preparing graphene intercalated lignin comprises:

[0010] Put H2SO4 in a reactor, add graphite powder and NaNO3 and stir to react, slowly add an oxidant, heat and stir to react, wash with deionized water after the reaction is completed to obtain a graphite oxide (GO) solution; add lignin to the GO solution and ultrasonically mix evenly, stir and dry; reduce the dried product with hydrazine hydrate vapor to obtain graphene intercalated lignin.

[0011] In some embodiments, the mass ratio of the graphite oxide solution to lignin is 2-24:1.

[0012] Preferably, the mass ratio of the graphite oxide solution to lignin is 18:1.

[0013] In some embodiments, the polymerized monomers of the composite conductive resin are 3,4-ethylenedioxythiophene (CAS: 126213-50-1) and N-(3-sulfopropyl)-3,3',5,5'-tetramethylbenzidine (CAS: 102062-36-2).

[0014] In some embodiments, the molar ratio of 3,4-ethylenedioxythiophene to N-(3-sulfopropyl)-3,3',5,5'-tetramethylbenzidine is 1:0.5-1.

[0015] In some embodiments, the preparation method of the composite conductive resin includes: mixing sulfuric acid and 3,4-ethylenedioxythiophene to form a mixed solution, slowly adding an emulsifier and an oxidant, continuing the reaction, adding N-(3-sulfopropyl)-3,3',5,5'-tetramethylbenzidine solution, continuing polymerization, washing with distilled water until the supernatant is colorless, filtering, and drying to obtain a composite conductive resin.

[0016] In some embodiments, the solvent is one or more combinations of ethylene glycol monoalkyl ether, ethylene glycol dialkyl ether, polyethylene glycol monoalkyl ether, polyethylene glycol dialkyl ether, propylene glycol monoalkyl ether, propylene glycol dialkyl ether, polypropylene glycol monoalkyl ether, polypropylene glycol dialkyl ether, ethylene glycol monoalkyl ether carboxylates, polyethylene glycol monoalkyl ether carboxylates, propylene glycol monoalkyl ether carboxylates, polypropylene glycol monoalkyl ether carboxylates, terpineol, dihydroterpineol acetate, turpentine, dimethyl sulfoxide, N-methylpyrrolidone, cyclohexyl acetate, 2-methylcyclohexyl acetate, 4-tert-butylcyclohexyl acetate, and dibasic acid esters.

[0017] In a second aspect, the present invention also provides a method for preparing the above conductive material, which specifically comprises:

[0018] Adding the composite conductive resin into a solvent to dissolve and mix evenly to obtain a mixture A;

[0019] Adding graphene intercalated lignin to the mixture A, adding sodium hydroxide, mixing and reacting, to obtain a mixture B;

[0020] The auxiliary agent is added into the mixture B, and the mixture is rolled and mixed evenly to obtain the conductive material.

[0021] Lignin is one of the main components of wood. It is a natural insulating material, so materials with high lignin content may have poor conductivity. In practical applications, if the lignin content in a material is high, it usually leads to an increase in the resistance of the material, thereby reducing its conductivity. Lignin can attract termites to gnaw on it. When the inventor wants to prepare a conductive material that can attract termites, it is necessary to add lignin to the material. However, the addition of lignin will reduce the conductivity of the material, so the modification of lignin or conductive materials has become the focus of the present invention.

[0022] The lignin layer is inserted into the interlayer of graphene. GO rises and falls with the lignin. Lignin acts as a "spacer" and is intercalated into the GO layers to form a 3D network structure, which effectively improves the overall mechanical properties and is beneficial to the transmission of ions.

[0023] In a third aspect, the present invention further provides a termite trapping device, the device comprising a trapping module and a detection module;

[0024] The trapping module comprises a shell with a through hole and a trapping bait placed in the shell;

[0025] The detection module includes a front end and a cloud, the cloud includes a display terminal and an alarm terminal, the front end includes a detection system including a conductive sheet installed on a shell, the conductive sheet is cut from the conductive material that attracts termites, the conductive sheet forms a closed circuit with the wire and the signal transmission device to constitute a detection system, and can transmit electrical signals to the alarm terminal.

[0026] In some embodiments, a drainage layer is connected to the bottom of the shell, and drainage holes are provided at the bottom of the drainage layer;

[0027] The front end also includes a temperature and humidity probe, a monitoring probe, a positioning system and a logistics network module which are respectively installed on the shell, and the monitoring probe faces the inside of the shell; the temperature and humidity probe, the monitoring probe, the positioning system and the logistics network module are wirelessly connected to the display terminal.

[0028] When there is a gap on the surface of a conductive material, the gap will affect the current value of the conductive material. The gap in the conductive material will increase the resistance and may cause the current to be locally concentrated at the gap, thereby generating local heating. This heating may cause the temperature of the conductive sheet to rise, thereby affecting its conductive properties. In addition, if the gap is large, it may also cause the path of the current to change, thereby changing the resistance of the entire circuit. Therefore, the above-mentioned conductive material can be applied to the termite trapping device, and the conductive material's own characteristics can be used to lure termites to gnaw, causing the current value to change, thereby triggering an alarm, and achieving more convenient maintenance.

DETAILED DESCRIPTION

[0036] The present invention will be described below in conjunction with specific embodiments. It should be noted that the following embodiments are examples of the present invention and are only used to illustrate the present invention, but not to limit the present invention. Other combinations and various modifications within the concept of the present invention may be performed without departing from the spirit or scope of the present invention.

[0037] Unless otherwise specified, the chemical reagents used in the present invention are all commercially available analytically pure.

[0038] Preparation of graphene intercalated lignin (GO-G-1):

[0039] 100 mL of anhydrous concentrated H2SO4 was measured with a measuring cylinder and placed in a reactor. The mixture was cooled to 0°C and iced. 4.0 g of 325 mesh graphite and 1.5 g of NaNO3 were added. The mixture was stirred magnetically for 15 min. 13 g of KMnO4 was slowly added dropwise and stirred magnetically at 20°C for 10 h. After the reaction, 100 mL of deionized water was added to the reactor. The mixture was stirred continuously and heated to room temperature. 10 mL of H2O2 was added dropwise. The mixture was stirred magnetically for 30 min. 150 mL of deionized water was added again. The suspension was allowed to stand for stratification. The lower layer of solution was taken and washed with 5% hydrochloric acid and deionized water to obtain a graphene oxide solution.

[0040] 10g of lignin was added to 20g of graphite oxide solution by ultrasonic homogenization, stirred for 8h and then dried; the dried product was fixed on a winding roller, placed in a container filled with hydrazine hydrate solution and sealed, the container was uniformly heated to 90°C to evaporate the hydrazine hydrate solution, and the product was reduced with hydrazine hydrate vapor for 10h. Subsequently, the reduced product was washed and dried with ethanol and deionized water to obtain graphene intercalated lignin 1.

[0041] The graphene oxide intercalated lignin 1 was subjected to infrared testing and it was found that the spectral peaks of most of the characteristic functional groups of GO were retained, and the peaks at 1150cm -1 There is a strong absorption peak at 1577cm, which is the stretching vibration peak of v-OCH3 on lignin; and GO and -1 The -COOH peak at does not appear in the spectrum of the product, which indicates that lignin was successfully grafted onto graphene oxide.

[0042] Preparation of graphene intercalated lignin (GO-G-2):

[0043] The preparation method of GO-G-2 refers to that of GO-G-1, except that the added amounts of lignin and graphite oxide solution are 10 g and 180 g, respectively.

[0044] Preparation of graphene intercalated lignin (GO-G-3):

[0045] The preparation method of GO-G-3 refers to that of GO-G-1, except that the added amounts of lignin and graphite oxide solution are 10 g and 240 g, respectively.

[0046] Preparation of composite conductive resin 1

[0047] 1 mol of 3,4-ethylenedioxythiophene was dissolved in 1 L of 1 mol / L sulfuric acid to form an EDOT solution. After stirring and dispersing, 0.4 mol of hexadecyltrimethylammonium bromide was slowly added and ultrasonically dispersed for 10 minutes. Then, 0.2 mol of ammonium persulfate was slowly added. After reacting for 2 hours, 1 L of 0.5 mol / L N-(3-sulfopropyl)-3,3',5,5'-tetramethylbenzidine aqueous solution was added and the polymerization was continued for 6 hours. After the reaction was completed, the composite conductive resin 1 was washed with distilled water, filtered, and dried.

[0048] Preparation of composite conductive resin 2

[0049] The preparation method of the composite conductive resin 2 is similar to that of the composite conductive resin 1, except that the concentration of the aqueous solution of N-(3-sulfopropyl)-3,3',5,5'-tetramethylbenzidine is 0.8 mol / L.

[0050] Preparation of composite conductive resin 3

[0051] The preparation method of the composite conductive resin 3 is similar to that of the composite conductive resin 1, except that the concentration of the N-(3-sulfopropyl)-3,3',5,5'-tetramethylbenzidine aqueous solution is 1 mol / L.

[0052] Examples 1-5

[0061]

[0062] Performance Testing

[0063] Tensile strength (MPa): Using a specimen having a thickness of 5 mm, the tensile strength was measured at a measuring rate of 5 mm / min in accordance with ASTM D638.

[0064] Surface resistance (ohm / sq): The surface resistance of a 5 mm thick sample was measured using PRS-801 (Prostat Co.); a 1 mm deep notch was made along the cross section of the sample and the surface resistance was measured again; the notch was deepened to 3 mm and the surface resistance was measured again.

[0065] Trapping efficiency: Place a 5mm thick, 5cm long and wide sample in a container with 50 termites and calculate the mass; measure the mass again after 24 hours and calculate the mass percentage of the sample. The higher the loss mass percentage, the better the material's effect in attracting termites.

[0066] The above test results are shown in Table 3.

[0067] Table 3 Test results

[0068]

[0069]

[0070] From the above test data, it can be seen that the conductive material provided by the present invention has the ability to attract termites due to the addition of lignin. At the same time, the conductive material of the present invention has excellent conductivity and high current sensitivity.

[0071] By modifying lignin with graphene, the conductivity of lignin in the resin system can be effectively improved, so that the material can attract termites and have excellent conductivity, such as Examples 1 to 5. When lignin is not modified, as shown in the experimental data of Comparative Examples 3 or 4, the surface resistance increases and the sensitivity decreases due to the addition of lignin, or the material cannot attract termites, and thus cannot be used in a termite trapping device.

[0072] The present invention dopes the composite conductive resin with graphene intercalated lignin, bonds the graphene intercalated lignin to the composite conductive resin through chemical bonds, and forms a conductive cross-linked polymer with a conjugated structure, which is more conducive to the propagation of electrons, so that the obtained network-like conductive and thermally conductive filler has better and more sensitive conductive properties, thereby promoting the development of conductive materials.

[0073] Example 6

[0074] Figure 1 This is a structural diagram of a termite trapping device provided in Example 6 of the present invention.

[0075] The termite trapping device provided in this embodiment includes a trapping module 1 and a detection module 2.

[0076] The trapping module 1 comprises a shell 11 with a through hole 15 and a trapping bait 12 placed in the shell 11;

[0077] The detection module 2 includes a front end and a cloud, the cloud includes a display terminal and an alarm terminal, the front end includes a detection system 215 installed on the shell 11 and including a conductive sheet 2131, the conductive sheet 2131 is cut from the conductive material for attracting termites prepared in Example 2, the conductive sheet 2131 forms a closed circuit with the wire and the signal transmission device to constitute the detection system 215, and can transmit electrical signals to the alarm terminal.

[0078] A drainage layer 13 is connected to the bottom of the shell 11 , and a drainage hole 14 is provided at the bottom of the drainage layer 13 .

[0079] The front end also includes a temperature and humidity probe 211, a monitoring probe 212, a positioning system 213 and a logistics network module 214 which are respectively installed on the shell 11, and the monitoring probe 212 faces the inside of the shell 11. The temperature and humidity probe 211, the monitoring probe 212, the positioning system 213, and the logistics network module 214 are wirelessly connected to the display terminal.

[0080] The shape of the shell 11 in the above content can be any shape suitable for placing the termite control agent, for example, it can be cylindrical, cube, rectangular or polygonal, but the present invention is not limited thereto and can be flexibly adjusted according to different needs.

[0081] In the foregoing content, the bait 12 is generally selected to have contact and or gastrotoxic drugs to termites, and termites will be poisoned after contact or ingestion, resulting in death. For example, it can be fipronil, fluridone, malathion, chlorantraniliprole, but the present invention is not limited to this, and can also be flexibly adjusted according to different needs. The number of the bait 12 can be 1, 2, 3, etc., but the present invention is not limited to this, and can be adjusted according to actual application needs.

[0082] In the above content, the shell 11 is provided with through holes 15, and the number and shape of the through holes 15 can be flexibly adjusted according to different needs to facilitate termites to pass through.

[0083] In the above content, the bottom of the shell 11 is connected to the drainage layer 13, which is composed of two mesh plates, and the mesh plates are horizontally placed at the bottom of the shell 11. A drainage hole 14 is provided at the bottom of the drainage layer 13. The drainage layer 13 and the drainage hole 14 are both conventional structures in the field and can be flexibly adjusted according to different needs.

[0084] In the above content, the temperature and humidity probe 211, the monitoring probe 212, the positioning system 213, the detection system 215 and the logistics network module 214 are all arranged at the inner top of the housing 11. The specific types of the temperature and humidity probe 211, the monitoring probe 212, the positioning system 213, the detection system 215 and the logistics network module 214 are all conventional settings in the art, and can also be flexibly adjusted according to different needs.

[0085] The material of the conductive sheet 2131 in the above content is not limited to the conductive material of the above embodiment 2, and can also be any one or more combinations of materials in embodiments 1, 3-5. The detection system 215 is formed by cutting the conductive material into a suitable shape, connecting the two ends with wires, and then forming a closed circuit with the signal transmission device.

[0086] The display terminal can be an information carrier such as a mobile phone terminal or a computer terminal, but is not limited to the above examples. The temperature and humidity probe 211, the monitoring probe 212, the positioning system 213, the logistics network module 214 and the detection system 215 transmit the information collected at the front end to the display terminal for display, so that the staff can obtain the current temperature, humidity, real-time dynamics in the shell, geographical location and other information of the termite trapping device when viewing the display terminal, which is convenient for information collection and processing.

[0087] The working principle of the termite trapping device provided in this embodiment is as follows: termites enter the trapping device through the through hole 15, and due to the lure of the killing bait 12 or the conductive sheet 2131, they gnaw on the killing bait 12 or the conductive sheet 2131. After the termites gnaw on the killing bait 12, they will be poisoned and die. Since the conductive sheet 2131 has excellent conductivity and sensitivity, the current transmitted by the conductive sheet changes during the gnawing process of the termites, and the electrical signal is wirelessly transmitted to the cloud by the signal transmission device. The termite trapping situation is judged by the change of the current value through automatic data analysis, and an alarm is realized. After receiving the alarm information, the staff can check the temperature, humidity, real-time dynamics in the shell, geographical location and other information collected by the display terminal, and check whether the stock of the killing bait 12 inside the termite trapping device is sufficient to determine whether the termite trapping device needs to be inspected or maintained.

[0088] Conventional termite trapping devices may also use some monitoring systems or alarm systems, but they do not use the conductive material provided by the present invention. Ordinary conductive materials cannot attract termites, resulting in termites not biting off the wires during the gnawing process, and thus failing to alarm. Although the capture of termites can be discovered by manually checking the monitoring system multiple times on the spot, it consumes manpower and material resources, and the timeliness and accuracy of the monitoring are poor.

[0089] In summary, the termite trapping device provided by the present invention combines the use of trapping and intelligent monitoring, which can both monitor termites and kill termites; it ensures that the visual intelligent monitoring system can clearly see the termite damage situation remotely, reduces the work links of frequent on-site inspections and verifications by staff, reduces the possibility of repeated monitoring work, and improves its practical application stability, efficiency, accuracy and environmental protection, so as to ensure that the intelligent integration of termite monitoring and trapping can be achieved during the application process.

[0090] The present invention can also have many other embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art can make various corresponding changes and modifications based on the present invention, but these corresponding changes and modifications should all fall within the scope of protection of the claims attached to the present invention.
