Description

Silica gel luminous fishing pendant and preparation method thereof

Technical Field

The invention relates to the technical field of fishing tackle, in particular to a silica gel noctilucent fishing sinker and a preparation method thereof.

Background

In recent years, with the acceleration of the urban process and the pursuit of people for the variety of recreational modes, the ancient and attractive fishing activities are re-initiated in the modern society, and become a popular recreational choice. It is particularly notable that the traditional fishing activity is gradually expanding from day to night, and night fishing activity gradually flows among many anglers, becoming a cradled way of fishing. However, with this revolutionary innovation, there are also unprecedented challenges.

Entering the field of fishing at night, the traditional fishing pendant becomes difficult to identify gradually due to weakening of ambient light, and the fishing effect is directly affected. Under the background, the luminous fishing pendant is unique in that the luminous fishing pendant can release soft and attractive light under the condition of darkness or weaker light, provides more excellent fishing experience for a fisher, and can also effectively attract the attention of fishes.

However, the traditional noctilucent fishing sinker manufacturing method has some obvious problems. Common manufacturing methods include painting noctilucent powder or internally-arranged noctilucent sticks. Although these approaches meet the need for noctilucence to some extent, their limitations are exposed. The fishing weight coated with noctilucent powder is easily affected by external environmental factors, such as water flow flushing, pendant impact and the like, so that the noctilucent effect is gradually weakened. On the other hand, the fishing sinker with the built-in luminous rod can have the problems of rod body fracture or liquid leakage in the use process, thereby affecting the luminous efficacy and even possibly causing potential pollution hidden trouble to the water body environment.

Furthermore, in modern society, fishing enthusiasts are increasingly diversifying and personalizing the requirements of fishing tackle. Traditional night light angles and weighs down and has been difficult to satisfy the various demands in market. The angler expects to obtain a more durable, stable, environmentally friendly and attractive luminous fishing weight to adapt to the requirements under different environmental conditions.

However, the current manufacturing method of the luminous fishing sinker on the market has serious problems. At present, most noctilucent fishing sinkers still use metallic lead as a main carrier, and a mode of spraying paint on the surface is adopted to realize noctilucent effect. However, this approach creates a series of challenges and concerns that are not negligible.

First, lead vapors and waste materials generated during the manufacturing process of metallic lead pose a threat to the health of the production personnel, as well as potentially contaminating the environment and water sources. Lead is a heavy metal that can cause serious ecological problems in the release into the water environment, jeopardizing the marine ecosystem and aquatic organisms. Lead pollution not only damages the marine ecological balance, but also can generate potential risks for human health, and the sustainable utilization of fishery resources is affected.

Secondly, the traditional manufacturing process of the metal lead noctilucent fishing sinker has great instability. The paint coating sprayed on the surface is easily influenced by external factors such as collision, friction and the like in fishing activities, so that the paint falls off, and the noctilucent effect is weakened and even lost. This not only affects the angler experience, but also wastes manufacturing costs and resources.

In addition, the manufacturing mode of the traditional metal lead noctilucent fishing bob is difficult to meet the personalized requirements of modern consumers. The requirements of anglers on equipment are becoming more diverse, and they desire to obtain more environmentally friendly, high quality and unique night-light fishing weights to enhance the fun and effect of fishing. However, the traditional manufacturing method can not effectively meet the requirements, and the innovation and development of the noctilucent fishing sinker are restricted. This has also prompted us to seek a new way of making to overcome the problems associated with the conventional methods and to meet the diverse needs of modern anglers.

In the preparation process of the noctilucent silica gel, each raw material plays a key role, and the characteristics and the performances of the noctilucent silica gel are constructed together. The specific role of each raw material in the present invention will be discussed in detail below:

methyl vinyl silicone rubber plays a critical role in the preparation of noctilucent silica gel, and takes up a larger proportion in the preparation process as a main matrix component. As a synthetic organic polymer material, methyl vinyl silicone rubber has attracted wide attention in the field of silica gel preparation by virtue of its unique performance characteristics. First, silicone rubber has excellent flexibility, which provides a solid support for the overall structure and shape retention of the luminescent silica gel. The flexibility allows the silica gel to accommodate a variety of complex application environments, such as external forces such as pulling, squeezing, etc. that are possible in fishing activities. The characteristic ensures the durability of the silica gel, enables a fisher to operate more freely when in use, and improves the practical feasibility of night fishing. Secondly, the methyl vinyl silicone rubber has excellent high and low temperature resistance. This feature enables the luminescent silica gel to maintain its stability and elasticity under various temperature conditions. For the fisher, the temperature change possibly faced is unavoidable, and the temperature resistance of the silica gel is excellent in both severe cold and high temperature environments, so that the reliability and stability of the noctilucent silica gel under different climatic conditions are ensured. In addition, the methyl vinyl silicone rubber also has excellent chemical stability. Silicone rubbers generally exhibit excellent corrosion and chemical resistance properties when exposed to chemicals, which enable the luminescent silica gel to retain its performance and luminescent effect in water, in humid environments, and in the presence of other chemicals that may be present. This is particularly important for anglers because the fishing activities tend to occur in complex and variable water environments. In general, methyl vinyl silicone rubber is taken as a main matrix of noctilucent silica gel, and lays a solid foundation for the successful preparation of silica gel by virtue of excellent flexibility, high and low temperature resistance and chemical stability. The application of the material not only ensures that the noctilucent silica gel has excellent physical properties, but also improves the practicability and reliability of the noctilucent silica gel in fishing activities to a great extent. Therefore, the wide application of the methyl vinyl silicone rubber brings great driving force and benefit to the preparation of noctilucent silica gel and the performance of fishing activities.

The white carbon black is used as a filler in noctilucent silica gel and plays an important role in the preparation process. The white carbon black with high specific surface area and adsorption performance has multiple important functions in noctilucent silica gel, and influences the performance and comprehensive characteristics of the silica gel. Firstly, the white carbon black can obviously enhance the consistency of the noctilucent silica gel. Because of the fine granular form, the silica gel can fill the gaps in the silica gel, so that the combination between silica gel molecules is more compact, and the overall consistency of the silica gel is improved. The thickening effect is not only beneficial to the processability of the noctilucent silica gel in the preparation process, but also can enable the silica gel to be more stable in the coating or forming process, and keep the required shape and size. And secondly, the white carbon black can effectively improve the mechanical strength of the noctilucent silica gel. By filling the silica gel matrix, the silica gel mass can be increased on a microscopic scale by the white carbon black, so that the mechanical properties of the silica gel such as tensile strength, compression resistance and the like are improved. This makes night light silica gel more stable under the external force action, difficult deformation or damage has improved the life and the reliability of silica gel. This increase in mechanical strength is critical to the durability and reliability of the silica gel, particularly in fishing activities. In addition, the white carbon black can also improve the rheological property of the noctilucent silica gel. The viscosity of the silica gel can be moderately increased by adding a proper amount of white carbon black into the silica gel, so that the fluidity and the dispersibility of the silica gel are improved. This is particularly important in the preparation of silica gels because good flowability and dispersibility help to ensure uniformity and stability of the luminescent silica gel, so that it can be better mixed with other ingredients, ensuring consistency of overall performance. Finally, the white carbon black can also realize uniform dispersion in the noctilucent silica gel. Because of the special surface property, the white carbon black can be mutually adsorbed with a silica gel matrix and dispersed in the silica gel, so that good mixing with other components is realized. The uniform dispersion is not only helpful for ensuring the consistency and stability of the silica gel, but also can enhance the action effect of other components in the silica gel, and improves the overall performance. In conclusion, the white carbon black is used as a filler in noctilucent silica gel, and plays an indispensable role in enhancing the consistency of the silica gel, improving the mechanical strength, improving the rheological property, uniformly dispersing and the like. The multiple functions of the luminous silica gel provide key technical support for preparation and application of the luminous silica gel, so that the luminous silica gel can show excellent performance and effect in fishing activities.

The hydroxyl silicone oil is used as an important component in noctilucent silica gel, and has extremely critical effect in the aspects of preparation and performance. As a special organic silicon compound, the hydroxyl silicone oil plays a plurality of important roles in the preparation process and the final performance of the noctilucent silica gel by virtue of the unique molecular structure and the functional group. Firstly, the thickening effect of the hydroxy silicone oil in the noctilucent silica gel is of great importance. Its unique molecular structure and functional group provide it with excellent thickening properties. The hydroxyl functional groups can perform hydrogen bonding with other components in the silica gel matrix, so that the interaction adsorption is realized on a molecular level. This interaction effectively increases the viscosity and tackiness of the silica gel, making the silica gel easier to handle during the manufacturing process, and capable of maintaining the desired shape and properties. Particularly, when preparing noctilucent silica gel, the thickening effect is helpful to stabilize the structure of the silica gel, so as to ensure that the silica gel can adapt to different process requirements and application scenes. Secondly, the hydroxyl silicone oil plays an important role in improving the rheological property of the noctilucent silica gel. The rheological properties of silica gels are directly related to their performance in processing, coating and use. The addition of the hydroxyl silicone oil can improve the slidability among silica gel molecules, so that the silica gel has fluidity and dispersibility. This is particularly important in the preparation process of silica gel, and good fluidity and dispersibility help to ensure uniformity and stability of silica gel, so that the requirements can be better satisfied in the manufacturing process of fishing equipment. In the aspect of crosslinking reaction, hydroxyl silicone oil participates in the crosslinking reaction of silica gel to form a 3D crosslinked network structure. This network structure imparts excellent strength, elasticity and abrasion resistance to the silica gel. The reaction between the hydroxyl functional groups and the vulcanizing agent can form stable cross-links in the silica gel matrix, thereby reinforcing the attachment of the silica gel molecules. The cross-linked network structure ensures that the silica gel can bear the action of external force in fishing activities, and keeps the shape and the performance, thereby improving the reliability and the durability of the silica gel in fishing. Finally, the adjustable property of the hydroxyl silicone oil enables the hydroxyl silicone oil to adjust the viscosity and viscosity of the noctilucent silica gel. By controlling the addition amount, the viscosity of the silica gel can be accurately adjusted, so that the silica gel is suitable for different process requirements and application scenes. The adjustability enables the silica gel preparation process to be more flexible, and can better meet the preparation requirements under different conditions. In conclusion, the multiple functions of the hydroxyl silicone oil in the noctilucent silica gel provide a vital support for the preparation and performance of the noctilucent silica gel from thickening, improving rheological property, participating in crosslinking reaction, adjusting viscosity and the like. The support enables the noctilucent silica gel to have excellent performance and effect in the field of manufacturing fishing equipment, and provides better use experience and effect for anglers.

The vulcanizing agent is used as an indispensable key component in noctilucent silica gel, has a critical role in the preparation process and final properties. As a special chemical additive, the vulcanizing agent plays a role as a crosslinking agent in the preparation and application of the noctilucent silica gel. Firstly, the main function of the vulcanizing agent Bispenta in the noctilucent silica gel is to realize the crosslinking reaction of the silica gel. The crosslinking reaction is an indispensable link in the preparation process of the noctilucent silica gel, and can connect the methyl vinyl silicone rubber and the hydroxyl silicone oil in a chemical bond mode to form a 3D crosslinked network structure. The cross-linked network structure enables the silica gel to maintain shape and performance under the action of external force, and enhances the strength, elasticity and wear resistance of the silica gel. Particularly in fishing activities, the durability and reliability of silica gel are critical to ensure the life and effectiveness of equipment. Secondly, the vulcanizing agent can promote a crosslinking reaction between the methyl vinyl silicone rubber and the hydroxy silicone oil. The cross-linking reaction is achieved by the action of a vulcanizing agent in the chemical reaction, which is capable of initiating the cross-linking reaction in the silica gel, so that different molecules are connected by chemical bonds. The generation of the cross-linking reaction enables the silica gel molecules to form strong connection and form a stable 3D network structure. This not only imparts excellent strength and elasticity to the silicone, but also enhances the durability and abrasion resistance of the silicone. In conclusion, the vulcanizing agent Bispenta is taken as the cross-linking agent in the noctilucent silica gel, and plays a vital role in realizing the cross-linking reaction, forming a 3D cross-linked network structure, endowing the silica gel with strength, elasticity, wear resistance and the like. Its nature and mechanism in chemical reactions enables silica gel to remain stable and reliable during fishing activities.

Stearic acid, mainly as one of the components of the mold release agent. Mold release agents play a key role in the manufacturing process, particularly in the preparation of silica gels. Stearic acid is introduced into the preparation of the noctilucent silica gel to ensure that the noctilucent silica gel can be successfully removed from the mold to achieve the desired shape and structure. In the preparation of silicone, the material needs to be filled into a mold and then processed and cured to form the desired silicone article. However, adhesion between the silicone material and the mold surface may occur in the mold, making it difficult for the article to escape from the mold. At this time, stearic acid acts as a mold release agent, and is applied to the mold surface to form a protective layer. The protective layer can reduce the adhesion between the silica gel and the mold, so that the silica gel can be taken out of the mold more easily after being solidified, and the integrity and shape of the product are maintained. Stearic acid can form a uniform coating over the mold surface. In this way, after the silicone curing is completed, the silicone article can be easily removed from the mold without additional effort or operations that may damage the article. This is important in the manufacture of high quality, consistent and reliable night light silica gel articles. Stearic acid is used as a release agent, so that smooth release of the silica gel is ensured, and a solid foundation is provided for preparing high-performance noctilucent silica gel products.

The inorganic luminescent pigment is an indispensable component in noctilucent silica gel, and plays a central role in realizing noctilucent effect. Such pigments have special optical properties that enable them to absorb energy in the presence of light and release luminescence in the dark. This phenomenon is known as the fluorescence effect, which is based on the electronic transition of a substance molecule under energy excitation, resulting in visible luminescence. Inorganic luminescent pigments are incorporated into luminescent silica gels in order to take advantage of this fluorescent effect to produce visible light in particular conditions. By adding inorganic luminescent pigment to the silica gel, the luminescent silica gel can emit soft light in night or dim environment, which is important for the visibility of the fisher and the fishing experience. During fishing activities, light may be limited, especially at night or in environments where light is darker. At this time, the noctilucent silica gel stores energy by absorbing energy in the daytime light, and emits light when the light is weakened or vanished. The luminous effect can provide a soft light, not only can assist a fisher to observe the position and the dynamics of the fishhook, but also can add a mysterious and fun to the whole fishing process. In night fishing, the addition of the inorganic luminescent pigment enables a fisherman to more accurately judge the position of the fishing tackle, the state of the fishhook and the activity condition of fish. This has a remarkable effect on improving the success rate of fishing and the satisfaction of fishing. Meanwhile, the luminous effect can also create a unique fishing experience, so that the fishing activity is not limited in the daytime any more, and the luminous effect can be unfolded at night, thereby increasing the fishing fun and diversity. In summary, the inorganic luminescent pigment, as a key component in the luminescent silica gel, not only provides a luminescent effect to the silica gel, but also provides better visibility and fishing experience to the fisher at night or in a dim environment. The technical innovation not only improves the success rate of fishing, but also enriches the fun and experience of fishing activities, and brings more comprehensive fishing experience for anglers.

The use of metal weights in fishing equipment is a multiple consideration. Metallic materials, particularly stainless steel, are widely used in fishing equipment, mainly because of their excellent corrosion resistance, strength and durability. These characteristics allow the metal weight to withstand time and environmental challenges in water in different fishing environments, maintaining its stability in performance and appearance. The corrosion resistance ensures that the metal pendant is not affected by oxidation or corrosion in water, thereby prolonging the service life thereof.

The choice of stainless steel material in a metal pendant is based on its high strength characteristics. This high strength allows the weight to remain stable during launch, retrieval and handling of water currents and the like. The pendant made of metal can be accurately put in the target area so as to attract fish better. Meanwhile, in fishing, the fishing tackle can possibly bear the actions of pulling, extruding and the like, and the high strength of the metal pendant can keep the integrity of the pendant and is not easy to deform or damage.

Secondly, metal weights of different shapes have respective application advantages in fishing activities. The weights with different shapes such as a cylinder, a cylinder-like body, a sphere, an egg-shaped body and the like can be selected according to the specific situation of fishing and the target fish type. The columnar body and the columnar-body-like pendant have smaller water resistance, are suitable for water areas with slower flow velocity, and can stay at specific positions more stably. The ball-shaped pendant is more suitable for water areas with high flow velocity, and the rolling mode of the ball-shaped pendant in water can better simulate the movement of bait. The egg-shaped pendant can generate tiny vibration when sinking, thereby attracting the attention of fishes.

In summary, the application of the metal weight in fishing equipment is a deliberate choice. The corrosion resistance, strength and durability of the metal pendant enable the metal pendant to play a stable role in various fishing environments. The weights with different shapes can optimize the fishing effect according to specific conditions, and better fishing experience and success rate are provided for the angler.

When referring to the preparation process of the noctilucent silica gel, these steps play a critical role in ensuring the quality and performance of the final product. The following is a brief introduction to the individual steps: mixing methyl vinyl silicone rubber, white carbon black and hydroxyl silicone oil: first, methyl vinyl silicone rubber, white carbon black and hydroxyl silicone oil were poured into an internal mixer in this order. The purpose of the internal mixer is to thoroughly mix and uniformly mix the raw materials to ensure that they are thoroughly dispersed and fused during the manufacturing process. This step typically takes 8 to 18 minutes to ensure that the raw materials are thoroughly mixed and ready for subsequent reactions. Adding a vulcanizing agent, stearic acid and a phosphor pigment: after the first step is completed, the mixed raw materials are taken out of the internal mixer and put into an open mill. Next, the vulcanizing agents biwu, stearic acid and the phosphor pigment were added to the mill. The purpose of this step is to introduce these critical ingredients into the mixture to achieve the desired reaction and properties. The vulcanizing agent Bispyrith is a cross-linking agent in the noctilucent silica gel, stearic acid plays a role in stabilizing and lubricating, and the inorganic luminescent pigment endows the silica gel with noctilucent effect. Evenly mixing: after the vulcanizing agent, stearic acid and the inorganic luminescent pigment are added, the mill is started to uniformly mix. The purpose of this process is to ensure that all ingredients are thoroughly mixed and fused to form a homogeneous luminescent silica gel mixture. The time and conditions of mixing may vary depending on the scale and requirements of the preparation, but in general, the aim of mixing is to ensure uniformity and stability of the ingredients. Preparing luminous silica gel: after the uniform mixing is completed, the obtained mixture is the final product of the noctilucent silica gel. The noctilucent silica gel can be processed and applied subsequently after the preparation process is finished.

The preparation method of the silica gel noctilucent fishing sinker comprises the following steps:

The preparation method of the silica gel luminous fishing pendant is a key process, and ensures that stable combination is formed between the pendant and luminous silica gel, thereby realizing luminous effect and the function of the fishing pendant. The following is a brief description of the various steps: (1) placing the weight into a mold: firstly, selecting a proper mould, and placing the pendant to be prepared in the mould. The selection of the mold can be made according to the shape and size of the desired luminescent silica gel interlayer. The purpose of putting the pendant into the mould is to ensure that noctilucent silica gel can wrap the pendant to form a sandwich structure. (2) heating and vulcanizing noctilucent silica gel: next, the previously prepared luminescent silica gel is heated and vulcanized. The purpose of this step is to make the noctilucent silica gel more stable and sturdy to facilitate its incorporation into the pendant, wrapping the pendant, and maintaining its shape during the manufacturing process. The heating temperature and time can be controlled according to specific silica gel materials and preparation requirements, so as to ensure that the vulcanization reaction is fully carried out. (3) forming a noctilucent silica gel layer made of silica gel materials: after the vulcanization process is finished, the noctilucent silica gel can form a stable silica gel interlayer. The layer of silica gel interlayer can completely wrap the pendant and encapsulate the pendant in silica gel. The silica gel interlayer not only protects the pendant, but also enables the pendant to have luminous effect. (4) preparing the silica gel noctilucent fishing weight: after the steps are finished, the silica gel luminous fishing sinker is prepared. The preparation process ensures the tight combination between the pendant and the noctilucent silica gel, thereby forming the fishing pendant with noctilucent effect. The prepared silica gel noctilucent fishing pendant can be used in fishing activities, and better visibility and fishing experience are provided for anglers.

However, the inventor finds in experiments that the prepared silica gel noctilucent fishing sinker also has the conditions of frequent pigment aggregation phenomenon, uneven overall luminescence, reduced mechanical properties of products and rough or uneven surface of the fishing sinker, and influences the attractiveness and the handfeel of the products.

In the experimental process, the inventor finds that the prepared silica gel noctilucent fishing sinker often has problems such as pigment aggregation, uneven luminous effect, reduced mechanical property and rough surface, which not only affect the luminous effect of the product, but also reduce the appearance and the hand feeling of the product. Through intensive analysis, the inventors believe that these problems are mainly caused by poor dispersibility between the inorganic luminescent pigment and the methyl vinyl silicone rubber.

To solve these problems, the inventors considered a new optimization strategy. First, it was decided to modify the inorganic luminescent pigment with a surfactant, particularly an acetylene glycol-based surfactant, to enhance its compatibility with and dispersibility in methyl vinyl silicone rubber. Next, by using a silane coupling agent in combination, the dispersibility of the luminescent pigment in silicone rubber is further enhanced. The optimization method not only improves the mechanical property and the luminous effect of the luminous silica gel, but also ensures that the surface of the silica gel luminous fishing pendant is smooth and the appearance is more attractive.

The acetylenic diol-based surfactant is a specific type of chemical substance used in the present invention to improve the dispersibility and surface properties of the inorganic luminescent pigment. The silane coupling agent is also used in the present invention to improve the dispersibility and surface properties of the phosphor pigment.

The specific preparation method is that the pigment dispersing agent and the inorganic luminescent pigment are mixed to improve the dispersibility, and then the operation is carried out according to the method provided before.

Furthermore, in order to increase the attraction to the fish and the interest of the fishermen, a certain amount of flavoring agent can be added into the luminous silica gel formula of the fishing weight.

Table 2: luminous silica gel stability test meter

Combining the data, analyzing the performance of the noctilucent silica gel:

pigment dispersant effect on performance example 1 did not add pigment dispersant, while examples 2-6 all used different pigment dispersants or combinations thereof. The samples containing pigment dispersant (examples 2-6) exhibited better performance in tensile strength TS and elongation Eb than example 1. In terms of tensile strength TS, the effects of example 4 and example 6 are most remarkable.

Luminescent pigment addition comparative example 1 no inorganic luminescent pigment was added. Although mechanical properties surpass other embodiments, this may be relevant to the fact that it does not contain luminescent pigments.

Stability index-stability performance test results were observed, examples 4 and 6 presented the best state in terms of rate of change of volume, suggesting that Surfynol DF110D may be beneficial for stability. The superior performance of comparative example 1 in stability may be attributed to its lack of use of luminescent pigment and pigment dispersant.

In example 6, the combination of Surfynol DF110D and the silane coupling agent A-172 brings about comprehensive performance improvement, and the related mechanism needs to be studied intensively.

Summarizing: the use of the pigment dispersant obviously improves the mechanical and stability indexes of the noctilucent silica gel, wherein Surfynol DF110D has good effect no matter being used alone or compounded with other pigment dispersants. While inorganic luminescent pigments may have some negative effect on performance, their critical role in luminescence in the product is indispensable and further improved by the addition of a preferred pigment dispersant.

The application scene of the silica gel noctilucent fishing sinker of the invention is as follows:

1. night fishing activity:

because of the characteristic of the silica gel noctilucent fishing pendant, the silica gel noctilucent fishing pendant can emit weak light in darkness, so that a fisher can clearly observe the position and the dynamics of the fishing pendant during fishing at night. The fishing device not only improves the fishing efficiency at night, but also provides more convenient and visual experience for fishing lovers.

2. Deep sea fishing:

in deep sea fishing, sunlight hardly penetrates deep due to the influence of water depth and surrounding environment, so that the underwater environment is dim. At this time, the silica gel noctilucent fishing pendant can be used as an obvious indicator to guide fishes to approach, so that the success rate of fishing is improved.

3. Fishing in a specific water area:

in certain areas of water, such as cloudy lakes or rivers, the line of sight is greatly restricted for water quality reasons. In this case, the brightness of the luminous fishing weight becomes an effective means for attracting fish.

4. Outdoor adventure activities:

for fishing enthusiasts who like adventure, they may be fishing in remote places or places where conditions are complex. Under the environment, the noctilucent fishing pendant not only can be used as a fishing tool, but also can be used as an emergency signal source, and when danger is encountered, the noctilucent fishing pendant can send out a distress signal to the outside by utilizing the luminous characteristic of the noctilucent fishing pendant.

5. Decoration and leisure activities:

besides the fishing function, the silica gel noctilucent fishing pendant can be hung on a knapsack, a tent or other outdoor articles as an ornament due to the unique luminous characteristic and the exquisite appearance, so that the pleasure of outdoor activities is increased.

In conclusion, the silica gel noctilucent fishing pendant not only provides the practicability of fishing by virtue of the unique luminous characteristic, but also increases the interestingness and safety of outdoor activities, and is suitable for various different occasions and environments.
