Description

Technical Field

[0001] The present invention relates to the field of mosquito coils, and in particular to a composition for bonding and breaking a disk-shaped mosquito coil, a preparation method thereof, and an application thereof. Background Art

[0002] As a mosquito repellent product, the disk-shaped mosquito coil has the advantages of stable structure, small space occupation, long burning time, and remarkable effect. Since its advent, it has been widely used. Although there are now more mosquito repellent and mosquito killing products available on the market, such as electric mosquito repellent liquid, mosquito repellent pads, and mosquito killing lamps, the disk-shaped mosquito coil (hereinafter referred to as "mosquito coil") is still popular among the people because of its low price and convenient use.

[0003] Before use, mosquito coils mainly go through four processes: production, storage, transportation, and disassembly, and often suffer from cargo damage (the incense body breaks). Summing up, there are three main reasons. One is the quality problem of the mosquito coil itself; the second is improper operation during storage and transportation; the third is the wrong method of disassembling the mosquito coil. Although the broken mosquito coil can still be used, compared with the complete incense body, the burning time is shortened, the mosquito repellent time is reduced, causing inconvenience. For small broken incense bodies, people often directly discard them, resulting in waste. This situation requires a good solution.

[0004] At present, there is no special remedial product on the market for bonding broken mosquito coils and immediately restoring their burning time. Many common adhesives can bond broken incense bodies, but some are not suitable for burning, and some even hinder burning. Adhesives can be classified into inorganic adhesives (such as silicates, phosphates, etc.) and organic adhesives according to their chemical composition. Organic adhesives are divided into natural adhesives (such as fish glue, starch, etc.) and synthetic adhesives (such as phenolic, polyvinyl acetate, etc.). Many types of adhesives will generate various toxic and harmful substances after burning, which is harmful to the health of the people and not suitable for bonding broken mosquito coils.

[0005] Although a binder is added during the production of mosquito coils, such as a new type of environmentally friendly binder provided in CN105885727A, which is prepared from potato starch by pre-treating the potato starch, carrying out a pre-gelatinization reaction, and then drying and pulverizing, and can be used as a mosquito coil binder in mosquito coil production. However, since it is a powder, it is not suitable for bonding broken mosquito coils. This binder belongs to the mosquito coil production link, and is an optional binder product. In the mosquito coil production link, it is used after being dissolved in a solvent (the main solvent in the mosquito coil production link is water). After dissolution, it has a high viscosity and strong adhesion, but water will hinder burning and is not suitable for bonding broken mosquito coils.

[0006] Although the adhesives in the sleep-aid incense mud disclosed in CN118976070A are water, glycerol, plant mucilage powder, and maltose, when using CN118976070A to prepare an incense mud that can achieve a sleep-aid effect through sniffing, the sleep-aid incense mud therein is through "sniffing", rather than burning, without the need for an open flame to ignite, and excessive water will hinder combustion and is not suitable for bonding broken mosquito coils. Summary of the Invention

[0007] The purpose of the present invention is to solve the above problems by providing a composition for bonding broken disk-shaped mosquito coils, its preparation method and application. The composition prepared by the compounding of wood mucilage powder and polyhydric alcohol has a certain viscosity, suitable viscosity, can be used quickly, is combustible and produces less smoke, accompanied by the smell of wood burning, is not pungent after burning, is more environmentally friendly, and is suitable for bonding broken disk-shaped mosquito coils. The present invention prepares a composition that can emergently repair broken disk-shaped mosquito coils, solves the problem that broken mosquito coils cannot be effectively utilized, avoids waste, and when in use, apply an appropriate amount of the composition to the fracture surface, press the joints for a period of time, light the mosquito coil, and the composition will ignite the broken incense body during the smoldering process.

[0008] The purpose of the present invention is achieved through the following technical solutions:

[0018] Further preferably, the wood mucilage powder is Phoebe zhennan mucilage powder. Due to factors such as origin, season, and processing technology, the compositions prepared from Phoebe zhennan mucilage powder from different sources have differences in viscosity, flexibility, and ductility, but all have the characteristics of high viscosity, good flexibility, and good ductility.

[0019] Further, the mesh number of the wood mucilage powder is 80 - 100 mesh.

[0020] Further preferably, the mesh number of the wood adhesive powder is 100 meshes.

[0021] Further preferably, the polyol is glycerol. Glycerol has the advantages of low price (low cost) and good safety. There are three hydroxyl groups in the glycerol molecule, while there are two hydroxyl groups in the propylene glycol molecule. Both glycerol and propylene glycol can be used to prepare the composition through the plasticization of the wood adhesive powder. More hydroxyl groups make the composition prepared from glycerol more advantageous in terms of viscosity, flexibility and ductility.

[0022] Further preferably, the glycerol is glycerol with a purity of greater than or equal to 99% (w / w).

[0023] Further, the propylene glycol is one or more of 1,2 - propylene glycol and 1,3 - propylene glycol.

[0024] Further preferably, the propylene glycol is propylene glycol with a purity of greater than or equal to 99% (w / w).

[0025] Further, the composition is in the form of a paste.

[0026] Further, the composition is in the form of a brown paste.

[0027] Further, when the temperature T1 is 25°C ≤ T1 ≤ 30°C, the dynamic viscosity of the composition is 790000 - 680000 cP.

[0028] Further, when the temperature T2 is 30°C < T2 ≤ 35°C, the dynamic viscosity of the composition is 670000 - 580000 cP.

[0029] Further, the composition is combustible, and the smoke during the combustion of the composition is a small amount of white smoke.

[0030] Further, there is a slight smell of wood burning during the combustion of the composition.

[0031] The second object of the present invention is to provide a preparation method of a composition for bonding a broken - disk mosquito coil, comprising the following preparation steps:

[0032] S1. Stir and mix the wood adhesive powder and the polyol by weight to obtain a liquid mixture;

[0033] S2. Heat the liquid mixture obtained in step S1, stir during the heating process, and obtain the composition after cooling.

[0034] Further, in step S1, the stirring and mixing is carried out by a stirrer, and the conditions for the stirring and mixing are to stir and mix at a rotation speed of 30 - 100 rpm for 0.5 - 1 h.

[0035] Further preferably, in step S1, a mixer is used for the stirring and mixing, and the conditions for the stirring and mixing are stirring and mixing at a rotation speed of 50 rpm for 0.5 to 1 h.

[0036] Further, in step S2, a scraping-bottom stirring jacketed pan is used for the heating, the heating temperature is 60 to 70 °C, and the heating time is 1 to 2 h; in step S2, the stirring rate during the heating is 10 to 30 rpm.

[0037] Further preferably, in step S2, a scraping-bottom stirring jacketed pan is used for the heating, the heating temperature is 60 to 70 °C, and the heating time is 1 to 2 h; in step S2, the stirring rate during the heating is 20 rpm.

[0038] Further, in step S2, until the bubbles on the surface of the liquid mixture disappear and it turns into a viscous paste, then it is cooled to obtain the composition.

[0039] The third object of the present invention is to provide an application of a composition for bonding broken coil mosquito-repellent incense. The composition is used for bonding broken coil mosquito-repellent incense, and the coil mosquito-repellent incense is a consumable that plays a role by burning.

[0040] Further, the process of using the composition for bonding broken coil mosquito-repellent incense includes the following steps: applying the composition to the broken surface of the coil mosquito-repellent incense and then performing docking pressing to bond the broken coil mosquito-repellent incense.

[0041] Further, the bonding of the broken coil mosquito-repellent incense can be achieved by pressing for several seconds. Therefore, it is suitable for emergency bonding of broken coil mosquito-repellent incense.

[0042] In the present invention, the wood adhesive powder is mainly derived from natural plants and is widely used in the incense-making process. After adding an appropriate amount of water, it plays a role in bonding and shaping the incense body; glycerol is a non-toxic, colorless, odorless, sweet, viscous liquid, which is applied in industries such as medicine, food, and cosmetics, and its combustion products are carbon dioxide and water. Glycerol and the wood adhesive powder are mixed in a certain proportion and processed into a composition through a process, which can provide a fast and simple bonding solution for broken mosquito-repellent incense.

[0061] The present invention will be described in detail below in conjunction with specific embodiments, but it is by no means a limitation to the present invention.

[0063] Example 1

[0064] This example provides a composition for bonding broken coil mosquito-repellent incense, including the following components in parts by weight: 1 part of nanmu adhesive powder and 4.4 parts of glycerol.

[0065] This example further provides a preparation method for a composition for bonding broken coil mosquito-repellent incense, including the following preparation steps:

[0066] (1) Prepare materials according to the following components in parts by weight: 1 part of nanmu adhesive powder and 4.4 parts of glycerol;

[0069] Comparative Example 1

[0070] This comparative example provides a commercially available paste.

[0071] Comparative Example 2

[0072] This comparative example provides a commercially available transparent soft fabric glue.

[0073] In the following application examples:

[0074] A is the composition prepared in Example 1, and A1 - A13 are samples applying the "composition";

[0075] B is the paste of Example 2, and B1 - B13 are samples applying the "paste";

[0076] C is the transparent soft fabric glue of Example 3, and C1 - C13 are samples applying the "transparent soft fabric glue".

[0077] Application Example 1

[0078] In this application example, samples of A, B, and C are taken for combustion comparison, and the results are shown in Table 1.

[0079] Table 1 Combustion comparison of A, B, and C.

[0080]

[0081] A can be ignited. During combustion, there is a small amount of white smoke and a slight smell of burning wood. The burned residue is a loose black solid.

[0082] B cannot be ignited, and a burnt smell is produced during the attempt to ignite it with a fire source.

[0083] C can be ignited. During combustion, a large amount of black smoke is produced, accompanied by a pungent plastic smell. The burned residue is a hard black solid.

[0084] Application Example 2

[0085] In this application example, samples of A, B, and C are taken for viscosity testing ( Figure 1 , 2 are schematic diagrams of the process of measuring the viscosity of A at 26°C and 32°C respectively), and the results are shown in Table 2 and Table 3. The viscosity testing process is as follows: Samples of A, B, and C are taken, put into a beaker, sealed, heated in a constant temperature water bath. When the internal temperature of the substances reaches 26 degrees and 32 degrees respectively, take them out and test the viscosity (dynamic viscosity) with a rotational viscometer. Each sample is tested three times and the average value is taken.

[0086] Table 2 Viscosity comparison of A, B, and C at 26°C.

[0087]

[0088] Table 3 Viscosity comparison of A, B, and C at 32°C.

[0089]

[0090] Under the same test conditions, when the internal temperature of the substance is 26 degrees and 32 degrees respectively, the average viscosity of A is higher than that of B and C.

[0091] Application Example 3

[0092] In this application example, samples of A, B, and C are taken for a suspension test, and the results are shown in Table 4. The suspension test process is as follows:

[0093] Take 24 mosquito coils, numbered A1 - A8, B1 - B8, C1 - C8 respectively. Each mosquito coil is about 5 cm long and weighs about 1 g. Cut each one in half. Apply A with a thickness of 0.5 - 1 mm on the fracture surface of A1 - A8, and press the two parts together for 10 seconds; apply B with a thickness of 0.5 - 1 mm on the fracture surface of B1 - B8, and press the two parts together for 10 seconds; apply C with a thickness of 0.5 - 1 mm on the fracture surface of C1 - C8, and press the two parts together for 10 seconds. All the bonded fractured mosquito coils (as Figure 3 shown), are suspended (as Figure 4 , 5 , 6, which are schematic diagrams of the suspension tests of A1 - A8, B1 - B8, and C1 - C8 respectively), and the states are recorded at different time points. When suspended, the indoor temperature is normal temperature, 25 - 26°C.

[0094] Table 4 Comparison of suspension tests of A, B, and C.

[0095]

[0096]

[0097] In Table 4, "√" indicates that the bonded fractured mosquito coil is stable and does not separate; "×" indicates that the bonded fractured mosquito coil is unstable and separates.

[0098] Under the premise that under the same test conditions, the gravity of the lower part of the fractured mosquito coil and the adhesive force of the mosquito coil fracture surface are in balance, A1 - A8, B1 - B8, and C1 - C8 can all remain stable for a long time. However, compared with the latter two, A1 - A8 will not solidify after being exposed to the air for a long time, and the adhesive force of its fracture surface cannot withstand excessive external forces. In practical applications, the lengths and weights of the accidentally fractured mosquito coil bodies are different. The mosquito coils adhesively bonded with A (the composition of Example 1) are suitable for use on a mosquito coil tray with spike teeth.

[0099] Application Example 4

[0100] In this application example, samples of A, B, and C are taken for a mosquito coil combustion application test, and the results are shown in Table 5. The mosquito coil combustion application test process is as follows:

[0101] Take 15 mosquito-repellent incense coils, numbered A9 - A13, B9 - B13, and C9 - C13 respectively. Each coil is about 4 cm long and is cut in half. Apply A with a thickness of 0.5 - 1 mm on the fracture surface of A9 - A13, and press the two parts together for 10 seconds; apply B with a thickness of 0.5 - 1 mm on the fracture surface of B9 - B13, and press the two parts together for 10 seconds; apply C with a thickness of 0.5 - 1 mm on the fracture surface of C9 - C13, and press the two parts together for 10 seconds. After all the fractured incense coils are bonded, light them and place them on a mosquito-repellent incense tray with spike teeth for testing.

[0102] Table 5 Comparison of the combustion applications of mosquito-repellent incense A, B, and C.

[0103]

[0104]

[0105] As Figure 7 、 8 、11、12 show, all the samples of A9 - A13 and C9 - C13 burned out normally. As Figure 9 、 10 shown, all the samples of B9 - B13 went out at the fracture. The water in B hindered the combustion.

[0106] By analyzing the above application examples, it can be concluded that the composition prepared by the present invention has the advantages of high viscosity, environmental protection, rapid bonding, and good emergency use effect. For the two comparative adhesives, the water in the paste hinders combustion. Although the transparent soft cloth glue can ignite the fractured incense coil, its components are vinyl acetate and various additives, and there is a pungent plastic smell during combustion, so it is not suitable for combustion. There are other common adhesives in life, such as 502 glue mainly composed of ethyl α - cyanoacrylate, white emulsion mainly composed of polyvinyl acetate, and adhesives with water as the solvent or dispersion medium like the paste. Based on factors such as environmental protection and application effect, these adhesives are not suitable for bonding fractured mosquito-repellent incense.

The composition prepared in this comparative example has certain viscosity, flexibility, and ductility. The water in it will hinder combustion and cannot be ignited, so it is not suitable for bonding fractured mosquito-repellent incense. After the finished product is air-dried, it is dry and hard and cannot bond fractured mosquito-repellent incense.

The sample burns out normally, indicating that the composition prepared by the present invention has long-term stability.

[0117] Application Example 6

[0118] In this application example, sample A was taken and placed in a beaker, and stored uncovered for 7 days. Glycerol in the composition has strong hygroscopicity.
