Fluorescent identification marking device for rope

The present invention relates to a fluorescent identification marker for a rope. In particular, the present invention relates to direct exposure to seawater during operations at sea or on water, and still completely prevents the hydrolysis of its surface, being struck by waves and surrounding vessels and various floating objects floating on the sea, or The external force, the surface damage, is also effective in preventing the breakage of fine bubbles, and the fluorescent identification device for ropes that functions as a fluorescent material is continuously exhibited. The present invention is a result of improvements in conventional nighttime identification marking appliances.

There are many types of vessels generally found at sea for the capture of aquatic products or for catching fish. Coastal piers adjacent to the coast use fiber ropes to carry these vessels.

Ships operating at sea use nets to capture a variety of fish. Conversely, in order to easily identify the presence of the net during or after work, various buoys of various shapes that float on the surface of the water are used.

Such buoys need to float on the surface of the water. Therefore, the specific gravity is lower than water, and it cannot be dissolved in water or corroded by water. It can be fixed by some kind of tangible material and is not easily damaged by external forces such as waves.

To date, such buoys have been mainly used for fiber ropes. The fiber rope is formed by twisting the filamentous fibers into strands and twisting together several strands. The fiber rope material uses a tougher material such as nylon, which is softer than steel wire rope and will not be corroded or corroded by seawater, so it is used in coastal docks or ships.

Conventional buoys are used in such fiber ropes, which are generally not problematic during the day, but cannot be accurately identified when the night or surroundings suddenly become dark. Therefore, in order to compensate for these defects, a buoy for night recognition has been developed. The nighttime identification logo and the nighttime identification buoy are used on the coast or at sea, and, in order to be at night Indirectly or in the dark, telling others about their position, or easily recognizing each other and the position of others, and mixing a small amount of fluorescent substances with the basic materials.

The conventional nighttime identification mark and buoy are Korean registered patent No. 10-985573 "Night buoy made of a mixture of waste rubber and waste synthetic resin" and Korean registered patent No. 10-1256083 "Night identification mark of rope" "." Korean registered patent No. 10-985573 "Night buoys made of a mixture of waste rubber and waste synthetic resin" with waste rubber and waste synthetic resin as the main raw materials, plus a small amount of EVA organic additive and a small amount of inorganic additives and a small amount of fluorescence Use together with pigments.

However, the waste rubber used in Korean registered patent No. 10-985573 is formed by instantaneously pulverizing the waste rubber block under the condition of liquid nitrogen at 170 ° C to 200 ° C. The technical difficulty is large and the required equipment is complicated.

The disadvantage is that in order to smash the waste rubber block, high technology and high investment must be used. Further, the technique used in the Korean Patent No. 10-1256083 "Night Identification Marking Device for Ropes" is to form a polyurethane foam, which is still added with a fluorescent substance during the formation of the foam, and is manufactured by using a fluorescent polyurethane foam. Identification of the identification device at night.

This technique was developed by the inventors to make many improvements to protect the safety of people working on the ropes at night or in the dark and the pedestrians around them. However, Korean Patent Registration No. 10-1256083 discloses that a polyhydroxy compound and an isocyanate are mixed in an appropriate ratio, and a urethane bond and a foaming operation are carried out after adding a fluorescent substance, and the manufacturing process is complicated and difficult.

This indicates that, due to the characteristics of the urethane, if the control cannot be precisely performed, it is difficult to ensure the quality of the product, and the foamed product may also be in an uneven state. Even if a foamed fluorescent article is manufactured according to Korean Patent No. 10-1256083, when it is used at sea, since the polyurethane foamed article is not resistant to moisture, the life of the product does not last long.

The reason for this may be that the urethane bond of the polyurethane foamed product is decomposed by moisture, resulting in the destruction of the closed cell structure forming the mesh structure. Polyurethane product of Korean Patent Registration No. 10-1256083 for seawater In the surface or in water, the seawater contains salt and plasma substances, which further promotes the destruction of the pore structure of the foamed product. For foamed products, the stability of the fine pore structure must be ensured. However, due to exposure to seawater, the surface of the foamed product is struck by or damaged by surrounding ships and various floating objects floating on the sea, resulting in further damage to the fine pore structure. damage.

All in all, the polyurethane foamed product has a nighttime fluorescent function even if it is added with a fluorescent material for nighttime recognition. However, it cannot be denied that the polyurethane foamed product is not resistant to water and cannot be fully utilized as a nighttime identification device. Performance and features.

Therefore, the inventors carefully investigated the conventional buoy as an identification mark and an instrument as a nighttime identification mark as follows.

Cutaway view of the line cut surface.

The present invention includes an elliptical body portion 110 formed of a plurality of fine bubbles and formed of an EVA material, and an EVA cylinder layer 120 formed at the inner inner center of the body portion 110. EVA materials include EVA copolymers. Preferably, both end ends of the EVA cylinder layer 120 further include an edge reinforcement portion 125. Preferably, the edge reinforcing portion 125 is formed of an engineering plastic having high abrasion resistance and impact resistance. The edge reinforcing portion 125 can be formed without foaming the EVA.

The present invention is composed of an EVA material including an elliptical body portion 110 formed of a plurality of fine bubbles. The elliptical body portion 110 includes a fluorescent EVA foam formed by foaming an EVA copolymer together with a fluorescent substance. In the fluorescent EVA foam, the fluorescent material is mixed in a state where the EVA copolymer and the epoxy resin are mixed and reformed, and it is preferable to foam the foaming agent again. The elliptical body portion 110 includes an EVA foaming portion 112 composed of a fluorescent EVA foam and an EVA surface layer 116 formed on the outer side of the EVA foaming portion 112.

According to the present invention, the elliptical body portion 110 is preferably 100 parts by weight of the EVA copolymer; 3 parts by weight to 15 parts by weight, and 2 parts by weight to 10 parts by weight of the blowing agent, based on 100 parts by weight of the EVA copolymer. 0.5 parts by weight to 5 parts by weight of the crosslinking agent and 0.01 to 2 parts by weight of other additives are foamed.

According to the present invention, the EVA copolymer uses a copolymer comprising a polyethylene resin and a vinyl acetate resin. The polyethylene resin is preferably one or a mixture of two or more selected from the group consisting of low density polyethylene, linear low density polyethylene, ultra low density polyethylene, and high density polyethylene. Vinyl acetate is preferably a vinyl acetate content of from 20 parts by weight to 40 parts by weight. When the vinyl acetate content is less than 20 parts by weight, the problem of less smoothness occurs during the molding process. On the contrary, if the vinyl acetate content is more than 40 parts by weight, the adhesion is strong and the problem is liable to occur, and the final product is too weak to be produced. select.

According to the present invention, even if the EVA copolymer is foamed, the urethane bond of the polyurethane is not carried out, the hydrolysis reaction does not occur in water, and the use time is longer, and the problem of discoloration does not occur for a long period of use.

In the present invention, it is preferred to uniformly mix the EVA copolymer and the epoxy resin into a reformed EVA copolymer. When the EVA copolymer is used, 0.1 to 5 parts by weight of the epoxy resin is uniformly mixed with respect to 100 parts by weight of the EVA copolymer. When the weight fraction of the epoxy resin used is less than 0.1 with respect to 100 parts by weight of the EVA copolymer, the epoxy component becomes weak, and the function of forming the binder and the surface layer cannot be fully realized. On the contrary, when the weight fraction of the epoxy resin is more than 5, The function of the hardener becomes stronger, and it is not suitable for consideration from an economic point of view.

According to the invention, the epoxy component is used at least for carrying out both functions.

The first of these functions is the function of the adhesive. This function enhances the chemical bonding between the EVA copolymer component and the fluorescent substance, and ultimately enhances the function as a phosphor of the present invention. Because, by chemical bonding as a binder, the functional group of the EVA copolymer and the functional group of the epoxy resin and the functional group of the fluorescent substance form a chemical hydrogen bond with each other. Specifically, the epoxy group of the epoxy resin ( The oxygen atom (-O-) and the EVA copolymer and the hydrogen atom (-H) of the fluorescent substance form a hydrogen bond through electrostatic attraction, forming a very strong bonding relationship, and the binding force through the hydrogen bond (-OH) The adhesion obtained by simply mixing the EVA copolymer and the fluorescent substance is stronger.

The second function is a solid surface layer forming function. Specifically, in the implementation of the manufacturing process of the present invention, the contact surface of the epoxy component with the mold surface of the injection molding machine generates a hardening reaction under high heat, and a strong epoxy hardened layer is formed on the contact surface thereof. The hardening reaction produced by the epoxy resin under the action of heat is well known in the art and will not be described in detail.

The third function of the epoxy resin is a strong bonding function with the edge reinforcing portion 125. Further, the edge reinforcing portions 125 are formed at both ends of the EVA cylinder layer 120 to perform this function, but the engineering plastic constituting the edge reinforcing portion 125 and the EVA copolymer component constituting the body portion 110 can be strongly combined by chemical bonding. Together.

On the other hand, according to the present invention, the application of the three functions of the epoxy resin component to the constituent elements of the present invention is different from each other. That is, the first function is applied to the constituent components of the EVA foaming portion 112 itself, and the second function is applied to the EVA surface layer 116 and the EVA cylinder layer 120 itself, and conversely, the third function relates to the body portion 110 and the EVA. The relationship between the cylinder layers 120. and also That is, as a result of the use of the epoxy resin component in the substrate component EVA copolymer of the present invention, the first function and the second function and the third function application field are different from each other, but these are collectively Formed a wonderfully coordinated relationship. As described above, the multiple functions of the epoxy resin component and the resulting reinforcing effect are the original techniques of the present invention which are not available in any conventional prior art.

According to the invention, from 3 parts by weight to 15 parts by weight of the fluorescent substance is used with respect to 100 parts by weight of the EVA copolymer. This fluorescent substance is a substance that receives light at night and absorbs light, and after the light disappears, the bright color is displayed to the outside by the energy received by the light. Fluorescent materials are also commonly referred to as fluorescent pigments, luminescent pigments, luminous pigments or light-storing pigments. The fluorescent substance does not contain radioactive substances or heavy metals, and is harmless to the human body. When the light is absorbed and stored and emitted, the luminosity is high, and it can be used semi-permanently. The fluorescent substance should be a chemically extremely stable crystal at a high temperature, and is excellent in heat resistance and cold resistance, and is excellent in chemical resistance.

According to the present invention, when the fluorescent substance is contained in an amount of 3 parts by weight or less based on 100 parts by weight of the EVA copolymer, the fluorescent property is not exhibited at night, and if it is more than 15 parts by weight, the fluorescent property is favored, but the amount of the fluorescent material is not large, and the fluorescent property is correspondingly Strengthened, so it is not appropriate to choose. The fluorescent substance is preferably used in combination with the reformed EVA copolymer.

According to the present invention, it may be produced by including 2 parts by weight to 10 parts by weight of a foaming agent with respect to 100 parts by weight of the EVA copolymer.

According to the present invention, the foaming agent foams a mixture including the EVA copolymer by using heat, and fine bubbles are formed in the process to form pores. The foaming agent is not particularly limited in terms of product selection as long as it is used for foaming of the EVA copolymer. Generally used at 130 ° C to decompose foaming agents, such as azobisformamide (ADCA), N, N'-tetrasulfide dipentamethylene thiuram (DPT), p, p'-oxo double Benzene sulfonium (OBSH), diphenyl hydrazine-3, 3'-diphosphoryl hydrazine (DS-33), and the like. When the amount of the foaming agent is less than 2 parts by weight, the performance of the foam is lowered. On the other hand, when it is more than 10 parts by weight, the fine bubbles are too large to be suitable.

The present invention is included in an amount of from 0.5 part by weight to 5 parts by weight based on 100 parts by weight of the EVA copolymer. The crosslinking agent is such that when the blowing agent decomposes to form fine bubbles, the EVA copolymer component has high-temperature viscoelasticity to withstand the gas pressure due to the blowing agent. The crosslinking agent is applicable to foaming of the EVA copolymer, and is not particularly limited. It is generally possible to use a hydrogen peroxide-based crosslinking agent, typically benzammonium peroxide, dicumyl peroxide, or a mixture of these substances. When the amount of the crosslinking agent is less than 0.5 part by weight, the crosslinking is insufficient to produce viscoelasticity, and if it is more than 5 parts by weight, the crosslinking is excessive and the formation of fine bubbles is easily inhibited.

The present invention is produced in an amount of 0.01 to 2 parts by weight based on 100 parts by weight of the EVA copolymer, including other additives. This other additive refers to a component which supplements the addition of a sufficient foaming action of the EVA copolymer, improves the crosslinking reaction, or further enhances the properties of the final product. This other additive is not an ingredient that must be added, but is any optional ingredient selected for use according to the manufacturing process or the final product, and is not particularly limited as long as it is generally used in the art. For example, a foaming accelerator, a crosslinking assistant, a softener, a flow improver, a filler, a colorant, or the like can be used as the other additive. This other additive may be used as a single component or a mixture of a plurality of components.

The invention is capable of mixing and mixing the EVA copolymer and the epoxy resin uniformly and preparing the EVA copolymer mixture in a reformed form, and then re-adding the fluorescent substance and the foaming agent, the crosslinking agent and other additives to the EVA copolymer mixture. After uniformly kneading, it is placed in the mold of the injection molding machine, and is heated inside the mold of the injection molding machine at a high temperature of 130 ° C or higher to form a fluorescent EVA foam.

In the present invention, an EVA copolymer mixture including a fluorescent substance is placed inside a mold of an injection molding machine to produce an EVA foam, but an elliptical body portion 110 and an EVA cylinder layer 120 can be simultaneously formed in the process.

The present invention is the result of an improvement in the defects existing in the conventional chloroformate-bonded foam, and the selection of the EVA copolymer and its reformed EVA The copolymer serves as a basic substance of the matrix, and a nighttime fluorescent substance is added to the basic substance of the matrix to have a specific function.

According to the present invention, the composition of the elliptical body portion 110 may include an EVA foaming portion 112 formed of an EVA foam, and an EVA surface layer 116 formed at the outer side of the EVA foaming portion 112. The EVA surface layer 116 is composed of a fluorescent EVA foam component, and the outer surface thereof is not formed with fine bubbles of the EVA foaming portion 112 to form a strong and strong surface layer. The EVA surface layer 116 is not formed separately or separately formed from the EVA foaming portion 112, but is bonded or bonded to the EVA foaming portion 112 at the same time using the same material and the same manufacturing process. The present invention includes an EVA cylinder layer 120 formed at the inner inner center of the body portion 110.

According to the present invention, the EVA cylinder layer 120 is constructed using a fluorescent EVA foam, and the outer surface of the EVA cylinder layer 120 is free of fine bubbles of the EVA foaming portion 112, and a hard, strong surface layer can be formed and formed into a circle. Cylindrical hole. The EVA cylinder layer 120 and the body portion 110 are not formed separately or separately formed by bonding or bonding, but are formed by using the same material and the same manufacturing process as the body portion 110, and simultaneously or rapidly performing the subsequent process. The fiber rope or wire rope is inserted through the EVA cylinder layer 120, so that the rope fluorescent identification device 100 of the present invention can be used on a ship or a dock.

In general, when the inserting rope is used, the EVA cylinder layer 120 is rubbed against the rope to be worn, or is subjected to external impact and is liable to be damaged. Therefore, the edge reinforcing portion 125 is formed at both ends of the EVA cylinder layer 120. The edge reinforcing portion 125 is preferably formed integrally with the manufacturing process of the body portion 110 after being fabricated by another process.

In accordance with the present invention, the EVA cylinder layer 120 preferably forms bump portions 122 at the ends of its sides, respectively. The bump portion 122 compresses the fiber rope or the wire rope after inserting the product of the present invention on the fiber rope or the wire rope to prevent detachment from the fiber rope or the wire rope or to be squeezed to other places.

According to the present invention, the edge reinforcing portion 125 is formed such that the inner surface portion of the cylinder is slightly convex, and the protruding portion finally functions as the bump portion 122 of the product. Shown in the drawings of the present invention is a circle that causes the edge reinforcement 125 An embodiment in which the inner surface portion of the cylinder is slightly convex to form the bump portion 122. According to the present invention, the bump portions 122 may be formed in plurality. Further, the bump portion 122 sandwiches the recessed portion formed by the strands of the fiber rope to prevent detachment from the fiber rope. The present invention provides a method of manufacturing a fluorescent identification marking device 100 for a rope. Fig. 3 is a view schematically showing a mold apparatus for manufacturing a method for using a fluorescent identification marker 100 for a rope using an injection molding machine. The present invention is preferably manufactured by inserting the upper and left center pins 61, 62 into the upper mold 51 and the lower mold 52, and filling the EVA copolymer mixture or the reformed EVA copolymer mixture through the filler tube 53. .

The inner side of the inner side is deep and the left center pin 62 and the right center pin 61 are inserted after being inserted into the end thereof. (See Figure 3a). In a state where the left center pin 62 and the right center pin 61 are inserted, the movable molds of the upper mold 51 and the lower mold 52 are moved to form a pair firmly with each other. (See Figure 3b). In a state in which the upper mold 51 and the lower mold 52 are engaged with each other, a melt of the EVA copolymer mixed melt or the reformed EVA copolymer mixture is melted by a filling pipe 53 on a screw (not shown) of the molding machine. The inside of the upper mold 51 and the lower mold 52 is filled. The upper mold 51 and the lower mold 52 are maintained at 130 ° C or higher in a heated state. (See Figure 3c). The melt of the EVA copolymer-mixed melt or the reformed EVA copolymer mixture in which the upper mold 51 and the lower mold 52 are filled is foamed by the internal foaming agent, and formed by the internal crosslinking agent. The cross-linking bonds, therefore, form a predetermined fluorescent EVA foam inside the upper mold 51 and the lower mold 52. The fluorescent EVA foam substantially forms the shape of the body portion 110 and the shape of the EVA cylinder layer 120 inside the upper mold 51 and the lower mold 52. Later, inside the upper mold 51 and the lower mold 52, the right center pin 61 is released from the mold. (See Figure 3d). Inside the upper mold 51 and the lower mold 52, the left center pin 62 is disengaged from the mold. In this state, the inner side ends of the EVA cylinder layer 120 are in a state in which the edge reinforcing portions 125 are respectively joined. (See Figure 3e). above After the right side center pin 61 and the left side center pin 62 are disengaged, the partial mold 51 and the lower mold 52 move the upper mold 51 corresponding to the movable mold, and take out the EVA foam molded product inside. (See Figure 3f). The present invention has been completed by this manufacturing process.

The bonding device 230 includes various devices that combine the first body portion 210 and the second body portion 220 to join the body portion on the cord. The first body portion 210 and the second body portion 220 are used in a state of being coupled to each other, and the first body portion 210 and the second body portion 220 are naturally combined to form the EVA cylinder layer 120. 4 is a view showing a preferred embodiment of the present invention, and FIG. 4a is a perspective view showing a substantially exploded state of the fluorescent identification marking device 200 for a rope according to an embodiment thereof, and FIG. 4b is a fluorescent identification marking device for a rope. Conceptual diagram of the 200 assembly state.

The present invention includes a body portion 110 formed of a plurality of fine bubbles and made of an EVA material, and an EVA cylinder layer 120 formed at the inner inner side of the body portion 110. In this state, the body portion 110 includes: a first body portion 210 that forms one side; and a second body portion 220 that corresponds to the first body portion 210 and that is combined with the first body portion to form a complete body.
