FIGS. 4 to 5 are block diagrams showing a procedure of a method for manufacturing a hot-melt adhesive and binding tape for horticultural use according to a preferred embodiment of the present invention;

The present invention relates to a thermally weldable binding tape for horticultural use in which a stem (20) and branches are bundled to a strut (30) or an incontinence strand so that a horticultural crop or a crop can grow properly, 7 to 10 parts by weight of an inorganic filler and 0.5 to 5 parts by weight of an inorganic filler are extruded and molded to form a film.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to FIGS. 1 to 5 illustrating embodiments of the present invention.

1, the tape is inserted into the tape cylinder 10 of the horticultural binder and taken out in the direction of the head 11 located in front of the horticultural binder, and then the cutting edge 12 Or cut by a hot wire for cutting and the two ends of the tape cut to a predetermined length are fused in such a manner that they are joined together by the hot wire 13 (or the hot wire 13 for cutting and combining).

At this time, the stem 20 or the branch of the crop is tied to the inside of the binding tape T to which both ends are bound, to the struts 30 or the man-in line.

The concrete construction of the horticultural binder will be replaced with a conventional horticultural binder which binds the binding tape T by a heat fusion method using heat by heat instead of iron. However, the binding tape T can be cut by the cutting blade of the horticultural binder or the cutting hot wire, and the binding heat wire 13 or the cutting hot wire (the cutting hot wire and the bonding hot wire 13) ), And are bonded together.

Specifically, in the present invention, the thermoplastic resin is a synthetic resin which is changed in shape due to heat when a certain heat is applied, melted and then hardened when cooled. In the present invention, the thermoplastic resin is a thermoplastic resin for cutting, 13).

That is, when the thermoplastic resin is made in the form of a tape having a certain thickness and width as a main component of the binding tape T, the thermoplastic resin may have a strength enough to bind the stem 20 or branches of the crop to the strut 30 or the man- And is a synthetic resin which is melted by heat generated from the hot or cold heating wire 13 of the horticultural binder and then bonded to each other and cured.

At this time, it is preferable that the thermoplastic resin has a melting point of 100 to 300 캜, which can be melted in heat emitted from the hot wire of a general horticultural binder. In addition, since the heat-sealable binding tape for horticultural use according to the present invention has a function of binding stem 20 or branches of a crop, if it is made of an excessively hard thermoplastic resin, the stem 20 or branches of the crop, It is preferable that a soft thermoplastic resin be used because a problem of being damaged by the thermoplastic resin (T) occurs.

The thermoplastic resin may be a commonly known thermoplastic resin, but is preferably composed of at least one of PVC, PE, and PP.

At this time, the PVC has a melting point of about 170 to 190 DEG C and is relatively strong in comparison with PE or PP. Therefore, the PVC is used for producing a binding tape T for supporting a thick stem 20 or branches having crops The PE has a melting point (LDPE: 110 to 125 ° C, HDPE: 132 to 138 ° C) of about 110 to 138 ° C and is relatively soft compared to PVC or PP. The PE has a functional additive (antistatic agent, , A biodegradation agent, a pigment, etc.) is added, and the PP has a melting point of about 160 to 170 ° C. and is excellent in impact strength and excellent in transparency. Therefore, the thick stem 20 ) Has the effect of increasing the transparency of sunlight and the support of crops having branches.

That is, the thermoplastic resin such as PVC, PE, or PP has properties other than those mentioned above. Therefore, the kind of the thermoplastic resin can be appropriately selected by a person skilled in the art depending on the kind of the crop and the growth environment.

The antistatic agent is mixed with 0.1 to 7 parts by weight of the thermoplastic resin to 100 parts by weight of the thermoplastic resin to prevent the binding tape T from being charged to reduce the static electricity that may be generated in the binding tape T.

That is, the antistatic agent exerts the function of dissipating the static electricity generated from the binding tape T or the static electricity externally applied to the binding tape T, and more specifically, the binding agent The static electricity of the tape T itself and the static electricity generated when the binding tape T is pulled out of the tape cylinder 10 of the horticultural binding machine is prevented or the generation of the static electricity generated when the stem 20 of the crop or the branch is bundled Or to dissipate generated static electricity.

At this time, it is preferable to use an antistatic agent such as a surfactant, an ionomer, a conductive polymer, a carbon or a conductive filler.

When the antistatic agent is contained in an amount of less than 0.1 part by weight, the antistatic agent is insufficient in antistatic effect, and when the antistatic agent is added in an amount of less than 10 parts by weight based on 100 parts by weight of the thermoplastic resin, If it is contained in an amount exceeding the amount by weight, the antistatic effect is excellent. However, there is a fear that the strength of the produced binding tape T is lowered and the binding tape T may be easily broken, and it is preferable to maintain the composition ratio within the above range .

In addition, the inorganic filler contained in the combination is used to improve the air permeability of the binding tape T by keeping the binding tape T in a state in which the stem 20 of the crop or the branch is tied to the strut 30 or the lead line, .

That is, when the formulation containing the inorganic filler is heated, extruded, molded into a film form, and then cut into an appropriate size to form a binding tape T, a part of the inorganic filler particles is exposed on the surface of the binding tape T The roughness of the surface of the binding tape T and the surface roughness of the binding tape T improve the friction between the binding tape T and the stem 20, the branch 30, ) Is prevented from easily flowing down or coming off from the stem (20), the branch, the support (30), or the manned line.

In addition, since the inorganic filler has a larger and larger number of pores as compared with the thermoplastic resin composed of a polymer, the air permeability of the binding tape T is improved, and in particular, the improved air permeability of the binding tape T Thereby realizing the effect of preventing the stem 20 or the branch of the crop from being rotten due to excessive adhesion of the binding tape T.

The inorganic filler may be at least one of calcium carbonate, silica, magnesium carbonate, barium sulfate, clay, talc, calcium oxide, titanium oxide, alumina, zeolite, potassium sulfate or barium carbonate. desirable.

At this time, the inorganic filler preferably has an average particle size of 10 to 400 mu m. That is, when the inorganic filler particles are less than 10 mu m, the inorganic filler particles are too small to disperse and mix into the thermoplastic resin to be mixed in the form of pellets. When the inorganic filler particles are more than 400 mu m, Because the stem 20 or the branch of the crop may be damaged by the inorganic filler particles which excessively protrude to the surface of the agricultural material T. [

If the amount of the inorganic filler is less than 0.5 part by weight, the inorganic filler may have a small composition and may provide the surface roughness and air permeability as described above. The inorganic filler may be added in an amount of 0.5 to 5 parts by weight based on 100 parts by weight of the thermoplastic resin. If the inorganic filler is contained in an amount of more than 5 parts by weight, the effect of ensuring the formation of surface roughness and air permeability is excellent, but the strength of the manufactured binding tape T is lowered so that the binding tape T may be easily broken , So as to maintain the composition ratio within the above range.

The combination of the thermoplastic resin, the antistatic agent and the inorganic filler may further comprise 0.1 to 3 parts by weight of at least one biodegradable material selected from the group consisting of starch, corn meal, rice husk powder and walnut shell powder per 100 parts by weight of the thermoplastic resin .

That is, the biodegradation agent is a constitution for promoting the natural decomposition of the binding tape T when the used binding tape T is discarded on the cultivated land. It is preferable that the biodegradable organic material constituting the binding tape T is decomposed before the thermoplastic resin And the biodegradable material is torn from the minute portion (where the biodegradation agent was present) of the binding tape T that has disappeared and disintegrated, thereby promoting the effect of promoting the undifferentiation of the binding tape T as a whole.

It is preferable that the biodegradation agent is included in the blend at a composition ratio of 0.1 to 3 parts by weight with respect to 100 parts by weight of the thermoplastic resin. When the biodegradation agent is contained in an amount of less than 0.1 part by weight, the biodegradability is insufficient, If the biodegradability is more than 3 parts by weight, the effect of promoting decomposition of the binding tape (T) is excellent, but the strength of the manufactured binding tape (T) is reduced and the binding tape (T) It is preferable to maintain the composition ratio within the above range.

In connection with the above, it will be apparent that additives such as pigments or ultraviolet screening agents may be further added in a certain composition ratio in order to improve the functionality of the binding tape (T) produced in the present invention.

In the present invention, the compound of the above-mentioned composition is drawn into an extruder heated to a predetermined temperature, and then formed into a film having a certain thickness and width, and then cut into a binding tape (T) The thickness of the film is freely configurable according to the judgment of a person skilled in the art, but it is preferable to have a thickness of 0.1 to 0.5 mm.

That is, if the thickness of the film is less than 0.1 mm, the thickness is too thin, and the operator is the same as the binding tape T (the thickness of the film is the same as the thickness of the film. There is a concern that the binding tape T may be easily broken at the same time as it is difficult to handle the binding tape T. If the thickness of the film exceeds 0.5 mm, It is preferable that the thickness of the film is within the above range because the thickness of the bonding tape T is too thick and the bonding tape T is excessively stiff to cause a problem of low flexibility.

In addition, the present invention can coat the surface modifier to prevent the generation of static electricity on the surface of the film and easily dissipate the generated static electricity.

That is, the generation and dissipation of static electricity are generally influenced more by the surface resistance value than the internal resistance value of the object (binding tape T), and when the surface resistance value is large, the static electricity is more easily charged And the ability to dissipate the static electricity externally applied to the object also falls.

At this time, the surface modifying agent induces the surface of the binding tape T to have a specific electric charge, thereby preventing the generation of static electricity and dissipating the generated static electricity easily.

In addition, it is preferable to use polyacrylic acid (PAA) or polyamine (dimethylamine-co-epishlorohydrin-co-ethylenediamine) as the surface modifier.

That is, the PAA or PDMA-ECH-EDA is an ionic polymer material. When the PAA is an anionic polymer and is included in the surface modifier and cured, the coating layer has an anionic property, so that an anionic substance in the air, Or PDA-ECH-EDA is adsorbed on crops. On the other hand, when PDMA-ECH-EDA is incorporated in a surface modifying agent as a cationic polymer and cured, the coating layer is cationic so that crops are cultivated in a state where a large amount of cationic substances are distributed in the air , The effect of preventing the cationic substance from being adsorbed to the binding tape (T) or crops is realized.

Specifically, the PAA is an anionic polyelectrolyte material having an average molecular weight of 15,000 to 250,000 Da. At this time, PAA is a polymer acrylic acid and has an excellent coating power on the surface of the film.

Also, when the average molecular weight of PAA is less than 15,000 Da, the molecular weight of PAA is too light and the coating power of the film is insufficient. When the molecular weight exceeds 250,000 Da, the coating power is excellent. However, It is preferable to use those having an average molecular weight within the above range.

In connection with the above, the PAA of the present invention may be a solution dissolved in a sodium salt solution in order to secure a constant viscosity and to prevent the PAA coated on the surface of the film from flowing down.

When the surface modifier is PAA, it is preferable to have a concentration of 0.03 to 1.0 mM. That is, when the concentration of PAA contained in the surface modifier solution is less than 0.03 mM, the concentration of PAA is too low to cause a problem that the PAA has a desired thickness on the surface of the film and can not be coated. If the concentration exceeds 1.0 mM, Is too high to cause a problem that the PAA is excessively thickly coated on the surface of the film, it is desirable to maintain the concentration within the above range.

In addition, the PDMA-ECH-EDA is a polymer electrolyte material having a cationic property and more preferably an average molecular weight of 75,000 to 250,000 Da. At this time, PDMA-ECH-EDA has an excellent coating power against the surface of the film.

If the molecular weight of PDMA-ECH-EDA is less than 75,000 Da, the molecular weight of PDMA-ECH-EDA is too light, and the coating power of the film becomes insufficient. When the PDMA-ECH-EDA is more than 250,000 Da, However, since the process of coating the surface modifier containing PDMA-ECH-EDA on the surface of the film becomes difficult, it is preferable to use those having an average molecular weight within the above range.

If the thickness of the coating layer is less than 1 占 퐉, the thickness of the coating layer is too thin, so that the degree of the electrostatic repulsion due to ionization of the surface modifier may become insufficient. The problem arises that if the coating thickness exceeds 15 mu m, the coating thickness becomes too thick and the surface modifying agent can easily peel off from the surface of the film, so that the surface modifying agent has a coating thickness within the above range, It is preferable to be coated.

The coating layer of the surface modifying agent may be formed on only one side of the film or on both sides of the film.

In connection with the above, the surface modifier may further comprise a common additive such as an appropriate solvent, a viscosity modifier, a hardener or a defoaming agent depending on the kind of the main composition to be used.

The following is a description of a method for manufacturing a hot melt adhesive tape for horticulture according to the present invention.

First, a method for manufacturing a hot-melt bonding tape for horticulture comprises: a blend preparation step (S100) of preparing a blend containing 0.1 to 7 parts by weight of an antistatic agent and 0.5 to 5 parts by weight of an inorganic filler per 100 parts by weight of a thermoplastic resin; A forming step (S200) of blowing the extrudate to form a film by drawing the blend prepared in the preparation step (S100) into an extruder; A cooling step (S300) of cooling and winding the film formed in the forming step (S200); And a cutting step (S400) of cutting the processed film into a tape shape in the cooling step (S300).

Specifically, the blend preparation step (S100) is a step of preparing and mixing a thermoplastic resin, an antistatic agent and an inorganic filler in accordance with a composition ratio.

At this time, the mixing order of the thermoplastic resin, the antistatic agent and the inorganic filler (or the biodegradable agent) constituting the blend is freely adjustable according to the judgment of a person skilled in the art, and it is preferable to stir and mix for proper mixing among the compositions.

The forming step S200 is a step of blowing the extrudate into a film by drawing the blend prepared in the blend preparing step S100 into an extruder.

That is, although the extruder is somewhat different depending on the type of the thermoplastic resin as the main composition contained in the blend, when the blend is composed of at least one of PVC, PE, and PP, the temperature of the cylinder is 100 to 200 ° C And the temperature of the die is preferably maintained at 100 to 200 ° C.

Further, it is preferable that the blow molding die is mounted on the outlet of the extruder so that the extruded extrudate can be blow-molded in the form of a film. The blow-molded film passes through a plurality of guide rollers installed in the vertical direction, (S300) and then wound.

At this time, it is obvious that the thickness of the blow-molded film in the forming step S200 can be adjusted in accordance with the air pressure applied during blow molding and the discharge amount of the extrudate, and the cooling process of the film produced in the molding step S200 is blow- It is preferable that the film is configured to be cooled by a natural or a cool air while passing through a plurality of guide rollers passing through before the film is wound.

Further, the cutting step S400 is a process of making a plurality of small binding taps T by cutting the width in the longitudinal direction by loosening the wound film produced by the cooling step S300, (T) to have a width of about 5 to 25 mm.

At this time, the process of the cutting step (S400) can be carried out by various methods according to the judgment of a person skilled in the art. However, it is also possible to process the film by passing the film through a cutting stand on which a plurality of cutter blades are mounted in the width direction of the film, It is possible to rotate the cutting roller on which the cutter blades are mounted and to process the film by passing the cutter blade.

In addition, the film processed in the forming step S200 may be configured to be embossed or uneven on the surface of the film through the embossing roller or the irregular roller before passing through the guide roller for cooling and winding.

That is, of the films processed in the forming step (S200), the film before the cooling treatment is heated by the heat energy applied from the extruder and the blow dies, and when the heated film is pressed by the embossing rollers or the irregular rollers whose surfaces are protruded Continuous embossing or unevenness is formed on the surface of the film.

At this time, the embossing or unevenness can achieve the effect of ensuring the air permeability between the binding tape (T) of the stem (20) or the branch of the crop and preventing the damage of the crop by the adhesion of the binding tape (T).

Further, a certain portion (groove) of the binding tape T in which the unevenness is formed by the uneven roller has a thickness thinner than the other portions of the binding tape T in which the unevenness is not formed, so that the binding force of the binding tape T It is possible to obtain an effect that the binding tape T can be cut off spontaneously when it is not required.

That is, when the stem 20 or the branch of the crop bundled by the binding tape T grows thick, the binding tape T continuously receives the pressing force by the stem 20 of the crop or the volume expansion of the branch, T is cut off if it can not withstand the pressing force of the crop stem 20 or the branch, the groove realizes the effect of inducing breakage of the binding tape T.

In the cooling step S300, polyacrylic acid (PAA) or dimethylamine-co-epishlorohydrin-co-ethylenediamine (PDMA-ECH-EDA) And a surface modification step (S310) of surface coating with a thickness of 15 [micro] m, and then dried and wound.

That is, the surface modification step (S310) is a process of forming a coating layer on the surface of the film by cooling the formed film after the forming step (S200) and spraying the surface modifying agent on the surface of the cooled film.

At this time, if the surface modifying agent is directly sprayed on the surface of the processed film (S200), there is a possibility that the surface modifying agent sprayed in the form of fine particles due to the heat remaining in the film is vaporized, It is preferable that the surface modification step (S310) is performed after the cooling processing of step S300. However, even if the film is cooled, it will be apparent that heat generated by blow molding may remain somewhat.

Further, after the surface modifier is sprayed on the surface of the film to coat the surface modifier, it is possible to apply a predetermined heat or warm air to the film before winding the film, and after the film is dried, After performing once, winding process can be performed.

The following is a preferred embodiment of producing a heat-sealable binding tape for horticulture by the manufacturing method according to the present invention.
