Description

{ECO BUOYS TO PREVENT MARINE POLLUTION}

The present invention relates to an eco-friendly buoy, and more particularly, to an eco-friendly buoy that prevents damage to buoys due to waves and the like on the sea, thereby preventing marine pollution.

Generally, buoys used for aquaculture are buoys formed by using styrofoam and buoys formed by blow molding with synthetic resin. Among them, styrofoam buoys are widely used.

Conventional Styrofoam buoys are used by winding a binding wire on both sides of a cylindrical shape. Since a lot of force is applied to the bending groove, if the buoy is used for a long time, it is likely to be broken or deformed by waves, tides and tsunamis.

In addition, the styrofoam has a disadvantage that the surface is not smooth and the impact on seawater such as waves is transmitted as it is, so that it is easily broken or deformed.

In addition, if the buoy is damaged, it will cause pollution of the sea by broken fragments, and it is difficult to use even if the bending grooves are slightly damaged.

As shown in FIGS. 1 to 4, in buoys connected with ropes through the sea to be used for culturing or capturing fish, the present invention may include a body 100 and a pressing sheet 200 have.

The body 100 may be formed in a cylindrical shape using a synthetic resin panel, and a bent portion may be formed in a predetermined portion of the body 100 to receive a rope along an outer circumferential surface thereof.

The synthetic resin panel constituting the body 100 can be formed into a honeycomb structure.

As for the honeycomb structure, a representative example of a multi-cell structure is a honeycomb. In the case of a honeycomb, a finite repeating structure in a hexagonal air structure is similar to a honeycomb structure, .

It has been developed as a core of sandwich structure. It uses paper (Craft / Al), stainless steel, GFRP (glass fiber reinforced plastic) as the material.

Honeycomb's typical characteristics are widely used in ultra-high-rise interior and exterior panels due to its ultra-light weight, ultra-high load resistance, heat resistance, fire resistance and abrasion resistance.

In particular, in the case of honeycomb panels in which an aluminum stainless steel plate is adhered to the surface, the aluminum honeycomb can be perfectly bonded to various plates differently from conventional panels, and the panel itself can serve as a structure. I can do it.

Honeycomb panels, which are the most perfect flatness, are widely used as building materials and exterior materials with perfect smoothness and ultra lightness, excellent durability, high rigidity and excellent color pattern, perfect planar surface and smooth curved surface.

Especially, it has excellent structure in terms of light weight and heat insulation. It is lightweight panel with air content of 97% or more, and blocks heat conduction between sheet and sheet by forming air pocket of honeycomb. .

Other uses of the honeycomb include a top plate and an indoor wall plate of a kitchen utensil, and it is widely used in areas requiring strength such as skiing, table tennis, rackets, boards, exercises for gymnastic apparatuses and the like.

It is used industrially in various ranges such as main rotor for wind power generation, aircraft body and wing, dish antenna, high performance sound device, control box.

Therefore, the honeycomb structure having the above-described characteristics is advantageously applied to the variable wall member 12 in various aspects, such as durability and strength, while reducing the weight of the material itself.

The compression sheet 200 is a component of a synthetic resin material that surrounds the surface of the body 100 and is compressed and sealed to seal the body 100 to provide buoyancy to the body 100.

Examples of the synthetic resin used as the material of the body 100 and the pressing sheet 200 include a resin such as a polyethylene resin, a polypropylene resin, a phenol resin, a polyurethane resin, a polyamide resin, an acrylic resin, a urea / melamine resin, .

Here, the polyethylene resin and the polypropylene resin are firstly known as a polyethylene resin (PE), which is a heat resistant material and is widely used in kitchen utensils. Since it is easy to process, it is used in various product groups. It is hardly discolored even when exposed to sunlight for a long time. It is also used for children's toys with relatively safe material.

Specifically, polyethylene is a chain-like polymer compound produced by polymerization of ethylene. It separates crude oil of petroleum and separates naphtha part (outflow portion at 100 to 200 캜) and decomposes it to obtain about 25% Ethylene is fractionated, and the ethylene is polymerized to produce polyethylene (sometimes with branches).

CH2 = CH2- ... -CH2-CH2-CH2-CH2- Depending on the polymerization method, various types of polyethylene are produced. They are classified into low-density polyethylene and high-density polyethylene according to density.

At present, low density polyethylene (soft polyethylene) and high density polyethylene (hard polyethylene) are the main products. Low density polyethylene is produced in large quantities. Low density polyethylene is heated at a high pressure of 1,000 atm And is therefore commonly referred to as high-pressure polyethylene.

It is used for various containers, packaging films, fibers, pipes, packings, paints and the like. Buckets, cups and the like are made by extrusion molding. Industrial chemicals containers, liquid detergent containers, Molding), and the fiber has a high tensile strength of 9 g per denier, which is mainly used for industrial ropes and the like. In recent years, many packaging films are produced.

Next, polypropylene (PP) resin is a thermoplastic resin obtained by polymerizing propylene, and is used for bedding, matting, and thermos.

Propylene is produced with ethylene in the decomposition of naphtha in a petrochemical plant. The propylene is produced in the nucleic acid by using a chiglitane catalyst (typically a complex salt of titanium trichloride and diethylaluminum chloride), and propylene is fed at about 70 ° C. and 5 atm It is easily synthesized.

Has an isotactic structure and therefore the methyl groups are arranged in the same direction in the same direction as in the structural formula and the melting point is 165 ° C and the continuous use at 110 ° C is possible under a load.

The density is 0.9-0.91 and the crystallinity is large, but it drops to 70% or less after molding. The electrical property is excellent because it is made only of carbon and hydrogen, and is similar to polyethylene.

Polypropylene is one of the four generic resins together with polyethylene, PVC, and polystyrene. It accounts for 24% of the total weight of thermoplastic resin and is advantageous in terms of cost and environment. Applications include packaging film, stretch tape, Textiles, clothing, carpets, pipes, daily necessities, toys, industrial parts, containers and so on.

The pressing sheet 200 can seal the body 100 while adhering the parts touching each other by thermocompression bonding.

ZnO and ADCA are added to PP as a method of preparing a porous polypropylene sheet by hot pressing to adjust the temperature of the blowing agent to about 165 ° C.

These mixed powders were press-molded in a mold at a temperature range of 178 to 208 DEG C for about 3 minutes. 198 ° C, and 1.0wt% of the blowing agent.

At lower temperatures, formation of pores was not sufficient, and pores were distributed nonuniformly in the upper and lower portions, resulting in formation of larger pores while being concentrated on the side or upper portion. The density of the PP sheet thus produced was 0.518 g / cc, and the porosity was about 47%.

The eco-friendly buoy 10 of the present invention may further include a mesh network 210 made of a synthetic resin that is coated on the inner side of the compression sheet 200 to reinforce the rigidity.

The mesh net 210 and the press sheet 200 are mounted so as to correspond to a pair of rollers 50 facing each other and are adhered by using the adhesive 70, 50 may be provided with cooling water to cool the mesh net 210 by applying heat to the roller 50 on which the press sheet 200 is placed.

Here, the adhesive 70 can be formed by a hot-melt method. The hot-melt method is a method in which a thermoplastic resin is melted by heating, which is solidified immediately after the thermoplastic resin is melted by heating, A film-type hot-melt adhesive may be used.

That is, when the mesh net 210 is bonded to the press sheet 200 using only the adhesive 70, the integrity of the press sheet 200 and the mesh net 210 is deteriorated, and by the repeated fatigue load There is a case where the mesh net 210 is easily separated from the press sheet 200 or the press sheet 200 is torn by the mesh net 210.

In addition, when the heat sealing method is used to improve the integrity of the mesh net 210 and the pressure-sensitive adhesive sheet 200, the mesh net 210 relatively weak in heat may be melted or may be integrated with the pressure-sensitive adhesive sheet 200 It may happen that the function of reinforcing the tensile force, which is an original function of the mesh net 210, can not be faithfully performed.

The rollers 50 on which the press sheet 200 is mounted are heated so as to be able to sufficiently exhibit the function of the mesh net 210 while integrally adhering the mesh net 210 to the press sheet 200, 210 can be cooled and the bonding operation can be performed.

In addition, the body 100 can compress and press the pressure-sensitive adhesive sheet 200 while covering the front and back sides.

That is, the synthetic resin panels constituting the body 100 are closely contacted and thermally bonded to the both sides of the pressure-sensitive adhesive sheet 200 like a sandwich panel, thereby further improving the durability of the environmentally friendly buoy.

The eco-friendly buoy 10 of the present invention may further include an ultraviolet screening agent 300.

The ultraviolet screening agent 300 may be coated on the pressure-sensitive adhesive sheet 200 thermally pressed on the outer surface of the body 100 to block ultraviolet rays.

Ultraviolet rays are shorter wavelength than visible light and less visible than visible light. They are invisible radiation and have a wavelength of about 10 ~ 397 nanometers (nm). It is strong in chemical action and is a light source for sunlight or discoloration.

Therefore, the durability of the eco-friendly buoy 10 can be improved by coating the surface of the press sheet 200 with the ultraviolet screening agent 200.

As a method for manufacturing an eco-friendly buoy to prevent marine pollution according to the present invention, an operator can manufacture the body 100 of the eco-friendly buoy 10 by cutting a synthetic resin having a honeycomb structure into a cylindrical shape.

The pressing sheet 200 is cut corresponding to the body 100 and is adhered by thermocompression so as to fit the body 100 so as to surround and cover the body 100. Both ends of the body 100 are also press- And the body 100 is completely covered and sealed to provide buoyancy.

A mesh net 210 made of a synthetic resin material is adhered to the inner surface of the compression sheet 200 through heating and cooling to reinforce the tensile force of the compression sheet 200 to improve the durability and to prevent the body 100 from being damaged by waves Thereby reducing marine pollution.

Further, it is possible to prevent discoloration or deformation of the sunlight by coating the outside of the press sheet 200 with the ultraviolet screening agent 300.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, And such variations and modifications are intended to fall within the scope of the appended claims.
