  The present invention relates to a pontoon structure, in particular, a high strength pontoon structure having a strong bonding force, hygienic and environmentally friendly high strength used in kitchen utensils such as polyaramid polymer resin and tableware, which is a high-strength polymer resin used in engineering plastics as a material of pontoon Using polyolefin / polyaramid / teflon resin mixture containing Teflon resin as a material, high strength, smooth surface and hygienic, and pontoon block is combined by strong bonding method, breaking or loosening of pontoon block by wave, wind, etc. The purpose is to provide a pontoon structure does not occur.

  It is also an object of the present invention to provide various types of offshore structures employing the pontoon material and coupling method of the present invention.

  In addition, the pontoon structure used in the field closely related to daily life is to provide a beautiful pontoon structure by adding color filler, color polymer beads, artificial wood pattern, and artificial marble to give a beautiful appearance.

  The present invention relates to a high-strength pontoon with a strong bonding strength, polyaramid resin, which is an engineering plastic, to be used as a pontoon material to produce a high-strength pontoon, which is hygienic and environmentally friendly, and thus used as a top coating composition such as dishware or kitchenware. Polyolefin / polyaramid / teflon resin (= 1/1/1, based on weight) mixtures were used, and a new but strong crosslinked structure and a vertically bonded structure were employed to enhance the binding force between the pontoon blocks. Since the bonding force between the extremely strong pontoon block due to waves, wind, collision, loosening, breakage, separation does not occur pontoons and stacked pontoon block.

  In addition, by adopting the pontoon material and the bonding structure of the present invention, it is possible to manufacture various types of offshore structures by polymer resin processing methods such as molding, extrusion, sheeting, etc. The present invention relates to a pontoon structure with a beautiful appearance by adding color filler, color polymer beads, artificial wood pattern, artificial marble, etc. to give an aesthetic and beautiful appearance.

  Recently, due to the increase of water sports, development of marine resources, development of water cities due to the improvement of the quality of life, development of pontoons that collectively float on the sea or the inner surface of water is being actively developed. The basic principle of pontoons is to float in the water due to buoyancy caused by the specific gravity difference between pontoon material and water. In other words, in the case of a material that is lighter in weight than water, the principle of floating in water by buoyancy is applied. In recent years, a polymer resin such as plastic occupies most of the pontoon material. In particular, polyolefin resins and polystyrene resins, which are inexpensive and easy to process such as molding, compression, and injection, are mainly used as pontoon materials.

  However, pontoons have been used since ancient times, and rafts, logs, and marine houses in the tropics are all structures that apply the principles of pontoons. In recent years, as described above, various forms of pontoons using polymer resins are used. Structures are being developed. The pontoon has changed into a concept that refers to all types of structures floating on the sea, and in particular, floating bridges protruding long from the resort or private house to the sea, pontoon structures used in beaches or swimming pools, drilling platform, carriers, Various types of offshore dredgers, artificial pontoons used by the military, offshore buoys, offshore city structures, offshore city platforms, oil drilling platform platforms and offshore work platforms are being developed.

  As the main material of pontoons, all materials having a smaller specific gravity than water, such as waste tires, wood, and bins, can be used. Recently, synthetic resins such as polyolefin resins such as polyethylene and polypropylene, and polystyrene are mainly used. In recent years, the material of the pontoon is not particularly limited due to the various forms of the pontoon structure, and if the buoyancy is insufficient when installing at sea due to the use of synthetic resins used for the manufacture of the structure on land and having a small specific gravity difference from water. It is also used to attach a small specific gravity platform to the bottom of the structure.

  As marine activities increase as a means of resource development and environmental problems, the demand for pontoons has increased rapidly in recent years, and the development of materials and bonding methods of pontoons, various types of structures, and platforms at resolution have been actively conducted. The material of the pontoon, the method of joining the pontoon block, and the patent for the structure are Korean Patent Publication No. 1987-4863A, Korean Utility Model Publication No. 20-255981Y1, Korean Patent Publication No. 1998-84998A, Korean Patent Publication No. 1983-7352, International Patent Publication No. WO90 / 4537A , US Patent Publication Nos. US Pat. Is disclosed.

  However, the conventional pontoon material was mainly made of polyolefin such as polyethylene and polypropylene, but the price was cheap and easy to process.However, due to the weak pontoon strength, the pontoon structure was impacted by waves, wind, typhoons or tsunamis. For example, durability problems such as pontoons being destroyed, coupling mechanisms deviating from the pontoons, or the surface of the pontoons are cut out in the event of a collision with the shore or a collision with the sea floating material have been frequently raised. In addition, when polyolefin-based materials are used for pontoons, the glass transition temperature (Tg) of pontoons is low in the tropics or high temperature areas, causing pontoons to soften, which causes pontoons to recede or to increase friction. On the contrary, when used in low temperature fat or low latitude fat, polyolefin resin has a weak strength and has been pointed out to be broken even in a small impact.

  In addition, in the joining method of pontoons, the coupling force was weak by using a folding device, a fitting groove, or a screw installed on the surface of the structure. Therefore, in the event of a typhoon or tsunami, the coupling device is destroyed and released from the pontoon structure. Problems such as this have arisen as a big problem of the prior art.

  In order to solve the above problems, the present inventors measured impact strength and bonding strength of pontoons through repeated experiments with various kinds of pontoon materials and bonding methods, and thus, polyaramid polymer resins, which are engineering plastics used in high strength and high heat resistance fields, It has been found that the conventional problems can be solved by using a polyolefin / polyaramid / teflon polymer resin mixture including teflon resin used in tableware and kitchenware as a material of pontoons because it is environmentally and hygienic. In addition, as the coupling structure between the pontoon blocks, as can be seen in the accompanying drawings 1 to 4, in the horizontal direction of the pontoon block is provided with two coupling mechanisms located above and below the pontoon, in the longitudinal direction of the pontoon block It has two coupling mechanisms located at the left and right sides, and adopts a method of coupling the coupling mechanism with nut grooves (installed in the pontoon block), bolts and bolt fixing screws to provide extremely strong coupling force, and also to the outside of the pontoon block. Edo adopts a coupling mechanism consisting of coupling rods, bolts, and nuts (installed on the pontoon block) in the horizontal and vertical directions to provide extremely strong coupling force between the pontoon blocks. The present invention has been completed by discovering that no loosening, breaking or disengaging of the coupling device occurs.

  The pontoon material employed in the present invention is a polymer resin mixture of a novel material that has never been used conventionally in the pontoon field, and the internal and external double bond methods employed in the present invention have never been conventionally employed in the pontoon field. There is no new combination.

  Hereinafter, the technical problem to be achieved by the present invention has been described in detail.

  Therefore, the present invention prevents the destruction or damage of the pontoon caused by the weak strength of the pontoon material, which is a problem of the pontoon, which has been conventionally used, and also weakens the coupling force between the pontoon blocks, thereby destroying the coupling structure between the pontoon blocks due to external impact. It is to solve the problems of the prior art, and to provide a pontoon that can be applied in the manufacture of pontoons of various structures by inventing a pontoon with a beautiful appearance that was not conventionally.

  The present inventors have found the pontoon material and bonding method of the present invention through numerous experiments and physical property evaluations to solve the conventional problems, and the detailed configuration and operation of the present invention have been described below.

In the present invention, polyolefins / polyaramids / teflons including polyolefins such as polyethylene and polypropylene, which are conventionally used as materials of pontoons, aramids used as engineering plastics instead of polystyrene, and hygienic Teflon resins (= 1/1/1 , By weight) A resin mixture was used. Although resins such as polyolefin and polystyrene, which have been conventionally used, have an advantage of being inexpensive and easy to be processed, there are often problems of weak strength and poor durability such as heat resistance, which are vulnerable to external shocks and natural disasters. The present inventors include a high-strength poly aramid resin used in the engineering plastics field as a material of Puntun to solve these conventional problems, and includes a high-strength Teflon resin used in advanced experimental fields or kitchenware as a hygienic and environmentally friendly resin. In order to solve the conventional problem, a pontoon material having a very high tensile strength, high glass transition temperature and softening point was invented. Thus, the base resin of the pontoon of the present invention consists of a polyolefin / polyaramid / teflon (= 1/1/1, by weight) mixture.

  In addition, in the present invention, for the purpose of giving a beautiful appearance to the pontoon, 4.5 to 5.5 parts by weight of color filler and 2.5 to 3.5 parts by weight of color polymer beads were added based on 90 to 100 parts by weight of the base resin. When the color filler is added to the pontoons as the particles imparting color to the conventional inorganic oxide fine particles, the color filler also serves as a filler to improve durability of the pontoons. The size of the color filler is suitable for the average particle diameter of 0.1 ~ 5um. Polymer beads are added to give a dimensional effect in addition to the color to the pontoons, was prepared by mixing a polymer and a colorant, the size of the polymer beads is preferably about 0.1 ~ 1 mm.

  Artificial patterns are used to give a pattern to the outer surface of pontoons in some cases, and artificial wood patterns, which are usually used for wallpaper or floorboard, are mixed and added during pontoon molding or extrusion. For the purpose. Artificial wood pattern is used commercially available commercial products, the addition amount is suitable to add 0.5 to 1.5 parts by weight, based on 90 to 100 parts by weight of the base resin.

  Artificial marble plays the same role as polymer beads and is added to give the exterior of the pontoon a gorgeous appearance. The amount of addition is suitably included 2.5 to 3.5 parts by weight to 90 to 100 parts by weight of the base resin.

  Pontoons do not need to be considered for the appearance, aesthetics, and touch of pontoons when they are used in industry such as oil drilling platforms, platforms at high resolution, and ships.However, pontoons such as resorts, private beach bridges, swimming pool pontoons, and marine housing pontoons In the case of pontoons used during leisure or daily life, the convergence of appearance cannot be excluded. Most of the pontoon structure developed in recent years is mainly limited to the material of the pontoon, the bonding method, or a method of forming the structure, but in the present invention, the color filler, color polymer bead, artificial wood pattern Artificial marble was added to complete the pontoon with a beautiful appearance.

 Hereinafter, the structure of the present invention Puntun will be described in detail.

  The bonding structure of the present invention pontoon is a novel bonding method found by the present inventors through a number of experiments that the structure is completely different from the conventional bonding method, such as fitting type, paste type, Jangseong type.

  In addition, an example of the molding process of the present invention pontoon can be carried out as follows. 30 parts by weight of polyethylene, 30 parts by weight of polyaramid and 30 parts by weight of teflon resin were charged into the mixer and stirred for 10 minutes, 4.5 parts by weight of color filler, 2.5 parts by weight of colored polymer beads, 0.5 parts by weight of artificial wood pattern, and 2.5 parts of artificial marble. After further stirring for 20 minutes, the mixture was continued for 30 minutes while maintaining the mixer temperature at 120 ° C, and then further softened by passing the mixture of 120 ° C to 140 ° C high temperature state through an extruder. The fluorocarbon mixture can be added directly to a mold, an extruder or an extruder to produce a pontoon (the weight part represents a relative ratio between the components, not an absolute value). . Machining of nut grooves or the like installed in the pontoons can be facilitated with the instruments usually used for machining furniture, after the pontoons are cooled.

  Hereinafter, the durability (tensile strength, stamping strength, softening temperature) of the pontoon material developed in the present invention and the bonding strength of the bonding structure were measured. First, the pontoon of the present invention as described above to evaluate the binding force of the coupling structure of the pontoons in the horizontal * vertical * height = 0.1 m * 0.1 m * 0.1 m standard to be carried out by combining the four horizontal, vertical, height The pontoon samples of Examples 1-3 were prepared. In case of manufacturing sample for actual size, it is difficult to evaluate the bonding force on the scale of measuring equipment when it is combined in 4 steps of width, length and height, so the maximum sample size is within the range that is easy to evaluate. Samples of * vertical * height = 0.2m * 0.2m * 0.2m were prepared. As a sample for comparison, a sample manufactured by the same material and bonding method as that of a commercially available pontoon was manufactured to the same standard as in the example. The strength of the bonding force was used a large instron to measure the tensile strength of the material, the bonding strength was shown by comparative comparison between the Example and the comparative example, and the relative value when the bonding force of the comparative example was set to 100. Tensile strength was evaluated by repeating five times and the average value was measured. The error range was about ± 10%. In the evaluation of the binding force, in the comparative example, the loosening of the coupling device or the strength of the coupling device from the pontoon block is measured. In the case of the pontoon with the bolt-nut coupling structure of the present invention, the coupling force is measured by the coupling mechanism. It can be said to measure the breaking strength.

  Next, a specimen of width * length = 10cm * 1cm manufactured from the pontoon material of the present invention was manufactured for durability evaluation. For the comparative example, a specimen of width * length = 10cm * 1cm was made of the same material as commercially available pontoons. Was prepared. Durability evaluation was made by comparing the fracture strength, stamping strength, and softening temperature of the Examples and Comparative Examples. Fracture strength is a measure of the fracture strength of a pontoon single block, and the tensile strength of the fracture is measured by tensioning both sides after mounting the sample on the Instron, and shows the relative value when the tensile strength of the comparative example is 100. . Immersion strength is a measure of the force required to penetrate to a certain depth when the indentation measuring device is taken to the pontoon block, measured the force required to dig into 2mm, and showed a relative value when the comparative example was set to 100. Softening temperature was measured by DSC, which is a common equipment for measuring softening temperature and melting point.

  The structures, measurement items, and evaluation results of the following Examples and Comparative Examples are shown in [Table 1] and [Table 2], respectively.

  As can be seen in Table 2, in the case of the present invention pontoons by using polyethylene / poly aramid / polytetrafluoroethylene material instead of the conventional polyolefin or polystyrene material, the tensile strength and the peeling strength of the pontoon block itself is compared. It is remarkably superior to the example, so it can be confirmed that it is a tough material without change over time even when used in water for a long time at high temperature. Also, it can be confirmed that deformation does not occur even when used in high temperature areas such as the tropics or the desert due to the softening temperature. In particular, in the coupling structure between pontoon blocks, it has a horizontal coupling structure and a vertical coupling structure, and exhibits strong coupling force, so that no external shock or breakage caused by natural environment occurs, and an external coupling structure is also necessary. In addition, it can be seen that it forms a strong bonding structure.
