Description
The present invention relates to an aquaculture farm rich and a method of manufacturing the same by mixing the EVA resin and NBR (synthetic rubber powder) and foam molding, thereby increasing durability and being environmentally friendly and recyclable.
The rich are used to install fishing nets in aquaculture farms, and materials of EPS (styrofoam), PE or PP (injection resin), PVC (injection resin), and polyurethane (foaming) are used.
In the case of EPS (styrofoam) is to be molded by adhering to individual foam, such a rich material is weak and the hydrolysis has a problem that the entire use is impossible.
PE or PP (Injection Resin) and PVC (Injection Resin) are made by general injection type and are completed by bonding two pieces together. Therefore, it is difficult to use because the seawater enters the adhesive site and weakens the buoyancy, and the light fastness is weak, so that the material is weak and easily damaged when exposed to the sun for a long time.
Polyurethane is manufactured by molded foam, but its specific gravity is high, its price is high, and its hydrolysis is severe.
Improved rich people developed and used to replace the styrofoam resin until now can not technically solve the foam, and the upper and lower plates are separately molded and used to bond with an adhesive. However, while floating in the sea for a long time, the seawater seeps into the adhesive site and the adhesion is reduced, making it impossible to use.
In addition, a rich man manufactured by injecting PE or PP (injection resin) or PVC (injection resin) is weak in material when exposed to the sun for a long time, and thus is not easily obtained.
Therefore, the present invention is to provide a rich and durable that can withstand long-term in the sea where the resin is dissolved and foamed as a whole, there is no adhesion, the appearance is beautiful, there is no hydrolysis phenomenon, and as a whole there is no fear of seeping into the sea water and it is strong There is a purpose.
The present invention is completely foamed into one rich, there is no seam, there is no penetration of sea water, so the durability life is increased, environmentally friendly and recyclable using EVA as a material.
The rich for farming according to the present invention has a material characteristic and a morphological characteristic, and the main body 1 having 60 to 8% by weight of EVA resin and 20 to 40% by weight of NBR having the final rich form in one foam. Is a whole formed structure.
That is, in the conventional case, a plurality of parts are bonded to form one main body 1, but the present invention is characterized in that the entire body is foam-molded in the shape of the main body 1.
And the inside of the main body 1 is characterized in that a plurality of through the tunnel (2) is formed. The tunnel (2) may be utilized when installing by inserting a rope or the like, and also serves to protect the rich itself by dispersing the impact such as blue.
The rich of the present invention having such a structure is a first step of preparing a preform having a final rich form by mixing 60-8% by weight of EVA resin and 20-40% by weight of NBR into a mold; The second step of heating the mold to 130 ~ 170 ℃, foaming for 20 to 40 minutes; is prepared.
And a small amount of shellfish parasitic adhesion agent may be added to the first step. The shellfish parasitic adhesion inhibitors are antifouling materials disclosed in Korean Patent Publication No. 10-1992-0018171 (October 21, 1992) and antifouling materials disclosed in Korean Patent Publication No. 10-2003-0074241 (2003.09.19) Coating compositions, antifouling coating compositions disclosed in Korean Patent Publication No. 10-2008-0027718 (2008.03.28) and the like.
As for the usage-amount of shellfish parasitic adhesion inhibitor, about 1 to 10 weight% of EVA resin amount used is used.
In addition, the present invention penetrates a plurality of heating cores inside the preform after the first step, and the foaming temperature of 130 ~ 170 ℃ is conducted to the heating core during the foaming of the second step to deep inside the preform Even in the foaming step may be further added to facilitate the foaming to occur easily.
Such a rich man of the present invention is shown in Figure 1 the whole perspective view, Figure 2 is a cross-sectional view.
EVA (Ethylene vinyl acetate), a material that is a feature of the present invention, is a material obtained by copolymerizing ethylene and vinyl acetate, and has excellent elasticity, transparency, elongation, and tensile strength, compared to LDPE, which is a general homopolymer, and is environmentally friendly. There is a big characteristic that it is harmless to human body and is pollution-free material.
Due to the above-described material features, it is possible to carry out foam molding entirely, and also by forming the whole body, the durability is strong, there is no fear of breakage, and there is no adhesive part, and there is no damage due to hydrolysis and penetration of seawater.
In addition, due to the material properties, there is no problem of environmental pollution, and recycling is possible without discarding the end of endurance life.
Looking at the manufacturing stage of the rich of the present invention having such an advantage as follows.
The first step is to prepare a preform having a final rich form by mixing 60-8% by weight of EVA resin and 20-40% by weight of NBR into a mold. And although a small amount of shellfish parasitic adhesion agents can be added here, about 1 to 10 weight% of EVA resin amount is used.
Said preform is the complete form of the rich and appearance of the main body 1. Thus, by preforming the preform in the form of a complete rich, it is possible to foam molding as a complete rich by the material properties and the preform as a whole.
The shellfish parasitic anti-sticking agent used is to prevent the shellfish attached and parasitic when the rich of the final product is installed and used in the actual environment.
Immediately after the preforming as described above, the second step may be carried out in earnest to carry out foam molding in earnest, and before this, the heating core may be inserted into the main body 1.
The heating core serves to invert the temperature so that the foaming temperature can be easily reached inside the preform. Therefore, if a suitable number of heating cores are used according to the size of the rich, even a large rich can be foamed once.
The second step is to warm the mold to 130 ~ 170 ℃, and foaming for 20 to 40 minutes. The preform foams from 130 ° C. and most active foams occur at around 160 ° C. 20-40 minutes of foaming at the above temperature conditions is ideal.
The heat is transferred to the preform through the mold. The larger the preform is, the less heat transfer therein, which makes foaming difficult and longer.
Therefore, according to the present invention, a heating core can be provided inside the preform to ensure foaming when the body 1 of the rich man is large. This is as mentioned above, and the foaming step in the case where the heating core is installed may be heated both of the mold and the heating core.
Therefore, during the foaming of the second step, the foaming temperature of 130 to 170 ° C is conducted by the heating core to promote the foaming so that the foaming occurs easily even in the deep inside of the preform.
After the foaming is completed, the mold and the heating core are removed, and the rich man thus manufactured has a form in which a plurality of
Of course, the
