- thermoplastic cast provided with stacked finishes according to another embodiment of the present invention.
- thermoplastic cast according to the invention can be implemented by claim 1.
- the present invention relates to a composition of a thermoplastic cast used to wrap around, fix or correct a fracture site of a patient, wherein the cast according to the present invention comprises the structure 10 and the structure 10 and the skin as shown in FIG.
- the buffer pad 100 made of a foam is laminated on the surface to which the contacts.
- the structure 10 has a net shape by regularly forming a polygonal opening, wherein the cross section of the net-shaped side has a square shape having a height greater than the width so that sufficient rigidity against external force or impact can be secured. It is molded to have.
- the structure 10 is made of a polycaprolactone composite based on polycaprolactone (PCL, polycaprolactone).
- the overall shape of the cast including the structure 10 is the same as the Republic of Korea Patent Publication Nos. 10-1425883, 10-1414493, 10-1538642, 10-1538644, 10-1538645 Alternatively, as shown in FIG. 3, a plurality of wire rods cross each other diagonally to each other, and thus, the buffer pad 100 is stacked on the entire surface of the structure 10 having a mesh shape in contact with the skin.
- Polycaprolactone is used as a main material of the polycaprolactone composite constituting the structure 10, and the polycaprolactone used in the present invention is a kind of polyester produced by ring-opening polymerization of caprolactone, and is a crystalline polymer. It has a low melting point of 50 ⁇ 80?
- polycaprolactone (PCL) used in the present invention has a weight average molecular weight in the range of 20,000 to 80,000, which is used as a structure because the mechanical properties (impact strength) is low when the weight average molecular weight of polycaprolactone is less than 20,000. It is not possible to expect a role, and therefore, it is preferable to use a large molecular weight, but when the weight average molecular weight is larger than 80,000, the flexural strength and flowability become worse, which is not suitable as a material for injection molding.
- the melting point of polycaprolactone under the above conditions is about 50-80? It has a range, which makes it easy to cast on affected areas.
- the structure 10 is made only of polycaprolactone, since mechanical properties such as tensile strength are low, glass fibers or carbon fibers may be added to the main body (polycaprolactone) as a strength reinforcing agent to improve this.
- a structure 10 having the core 20 positioned therein and a buffer pad 100 made of foam are stacked on a surface where the structure 10 is in contact with the skin. .
- the core material 20 is made of a thermoplastic synthetic resin elastomer, it is preferable to use a melting point higher than the melting point of the structure (10).

- each side of the structure 10 has a rectangular cross-sectional shape that is relatively larger in height than the width, thereby ensuring sufficient rigidity against external force or impact.
- a structure 10 having a rubber skin 30 attached thereto and a buffer pad 100 made of foam are stacked on a surface where the structure 10 is in contact with the skin.
- the outer shell 30 is wrapped around the molten structure 10 to prevent excessive elongation of the structure to maintain the shape of the square forming the net shape while at the same time prevents the thickness of the thinning to prevent a decrease in strength and It can also function as a cushioning material for preventing the hard surface of the structure 10 from directly contacting the skin of the patient.
- the outer shell 30 is made of a rubber material in the Shore D 2 to 35 range because it must exhibit the appropriate strength and elasticity at the same time, which is a bad fit when in contact with the skin of the patient, absorbs the shock from the outside sufficiently Since it does not, it is somewhat buffered compared to the structure without the outer shell, but it is difficult to show a sufficient buffering effect.
- the structure 10 including the shell 30 and the buffer pad made of a foam is laminated on the surface in contact with the skin to be provided to achieve the desired sufficient effect in the present invention.
- Structure 10 in the present invention is excellent in formability when heated to a temperature of 70 to 80 ° to install on the affected part of the patient, and after being installed in the affected part has a strength that can withstand external shocks or external forces It should be of good flowability to be suitable for injection molding.
- the buffer pads stacked on the structure 10 should have a firm adhesive force with the structure 10 and should not be dropped, deformed, or broken by external force, moisture, heat, or the like.
- the buffer pad of this invention consists of foams.
- Elastomers include EPR, EPDM, ethylene-alpha olefin copolymers, styrene-based TPEs such as SBS, SIS, SEBS, butadiene-based rubber materials, thermoplastic elastomers such as TPO, or a mixture of two or more.
- the foaming ratio is preferably in the range of 5 to 40 times, more preferably in the range of 5 to 30 times.
- the foaming ratio is low, the mechanical strength is increased but the elasticity is decreased, and in the case of uncrosslinked foams having too high or uncrosslinked foaming cells at high temperatures, the foaming cells collapse and lead to product defects. It is desirable to.
- the buffer pad may be formed of two or more layers having different degrees of foaming.
- the foam pad with high foaming degree is easily bursting foam cells during melt bonding, the shock absorbing function of the buffer pad is not smooth and the fusion shape is worse.
- the cushion pad having a low degree of foaming is inferior in shock absorbing ability and wears poor. Therefore, by laminating pads with low foaming and pads with high foaming, make two or more layers of sheets, and use the parts with low foaming as the fusion and the parts with high foaming as contact with the skin. Two problems can be solved at the same time: improvement of shock absorption capacity.
- a foam made of a material having a low melting point such as EVA may be used as a part in contact with the skin, and a foam made of a LDPE material having a relatively high melting point may be used as a welded portion.
- the process of foaming the buffer pad of the present invention may be carried out by a crosslinked foam or a crosslinked foamed process.
- the crosslinking foaming process includes a chemical crosslinking foaming process and an electron beam crosslinking foaming process.
- a chemical crosslinking foaming process includes a crosslinking agent which forms radicals at a high temperature and causes a crosslinking reaction, and a foaming agent which decomposes at a high temperature to generate a gas, is mixed with a resin, It is a method of manufacturing a sheet by extruding at a low temperature such that a blowing agent decomposition reaction does not occur, and causing a crosslinking reaction and foaming while passing the molded sheet into a high temperature horizontal tunnel.
- the electron beam crosslinking foaming process does not use a crosslinking agent, and the foaming agent is mixed and extruded with a resin to produce an unfoamed sheet, and the crosslinking reaction occurs by irradiating an electron beam to the prepared sheet, and then into a high-temperature horizontal or vertical tunnel. It is a method of foaming by allowing foaming to occur while passing.
- non-crosslinked foaming process includes a method using a chemical blowing agent and a method using a gaseous blowing agent, the foaming is performed in the first extrusion process without crosslinking reaction.
- the cross-linked resin has a significantly increased viscosity and elasticity in the molten state, so the bubble is smaller and uniform than the non-crosslinked foam sheet, so that the foam has excellent elasticity, resilience, and soft touch. Therefore, since the cell is disintegrated, the non-crosslinked foam is not suitable for the buffer pad bonding process by the insert injection process of the present invention, and it is preferable to prepare the buffer pad through a crosslinking foaming process or an electron beam crosslinking foaming process.
- the buffer pad and the structure of the present invention are joined to the structure by insert injection.
- the method of joining the buffer pad and the structure includes a method of bonding using an adhesive and a method of thermally bonding at a high temperature.
- the adhesive may be bonded at a low temperature by applying the adhesive to one or both surfaces of the structure or the outer surface of the shell and the buffer pad, and then applying pressure and bonding the adhesive.
- the process is complicated and the use of liquid adhesives can lead to contamination of the workplace, which is undesirable since harmful components may remain in the finished cast.
- thermal bonding is a method of heating one surface of a structure or shell to be bonded and one surface of the buffer pad to a temperature at which the structure, the shell, and the buffer pad are at or above the melting point, and then applying pressure and bonding to each other.
- thermal bonding is a method of heating one surface of a structure or shell to be bonded and one surface of the buffer pad to a temperature at which the structure, the shell, and the buffer pad are at or above the melting point, and then applying pressure and bonding to each other.
- thermal bonding requires a process of molding the structure by insert injection or forming a structure surrounded by an outer shell, and then additionally bonding the buffer pad, process efficiency is inferior.
- the bonding process is performed by simultaneously bonding the buffer pads in the insert injection process without an additional process.
- the buffer pad in the form of a sheet is cut to have the same shape as the structure, and then inserted into the core of the moving plate of the mold for forming the structure or the shell.
- the rubber material constituting the outer shell is injection molded to form the outer shell while hot molten resin flows into the mold, and is bonded to the buffer pad by heat.
- the cast can be produced in a single step by enclosing the structure and adhering the buffer pad to one side thereof.
- the structure is molded by inserting a buffer pad cut in the same manner as the shape of the structure to be located in the core of the moving plate of the mold.
- the cast in the form in which the buffer pad is bonded by bonding to the buffer pad by heat can be manufactured in one step.
- the density of the buffer pad bonded to the cast was 0.03 to 0.1 g / cm 3, and it was confirmed that Shore C hardness is preferably 45 or less.
- the shock absorbing pad is too hard to significantly reduce the fit, and if too low, the durability is reduced to easily break or peel off.
- the peel strength according to ASTM D903 may be peeled from the structure by a conventional external force when manufactured to exhibit a value of 250N / 100 mm or more. The phenomenon does not occur can be exhibited excellent adhesion. When the peel strength was not sufficient, the cast pad was pushed to the floor and the buffer pad was partially peeled off or damaged. Therefore, it was determined that the peel strength was more than 250 N / 100 mm.
- TPE resin used as an outer shell material was carried out at 160-170 degree
- Example 1 As shown in Table 1, using a foam sheet having a different expansion ratio, thickness, and material, the remaining test methods were prepared in the same manner as in Example 1.
- An LDPE crosslinked foam sheet having a foaming ratio of 10 times and a thickness of 1 mm provided by Youngbo Chemical is cut into a net shape such as a mold cavity and inserted into the injection mold cavity to be placed.
- the polycaprolactone composite reinforced with glass fibers used as the structure was insert-molded at 150 ⁇ to prepare a cast in the form of a mesh in which foam sheets were laminated as buffer pads on one side of the structure.
- Example 10 As shown in Table 1, using a foam sheet having a different expansion ratio, thickness, and material, and the remaining test method, the cast was prepared in the same manner as in Example 10.
- the conventional cast was manufactured by insert-molding the outer shell by inserting only the structure into the mold without a buffer pad.

- LDPE / EVA is 70 wt% LDPA and 30 wt% EVA
- the LDPE buffer sheet was evaluated for density, tensile strength, elongation rate, tear strength, heating dimension change, hardness, and appearance by varying the expansion ratio.
- the visual evaluation was carried out by visual inspection, if the surface is good and there are no defects, if there is no problem in use even if there is some bonding,? If the foam cell is partially deformed? .

- Example 18 6.5 Comparative example 3.0
- the cast pads of Examples 1 to 18 were found to have better fit than conventional casts with only an outer jacket without a buffer pad.
- the fit score is relatively low, and it can be seen that the foam thickness and the foam ratio need to be adjusted according to the material of the buffer pad. In this case, Shore C hardness exceeded 45, resulting in a sharp decrease in fit.
- the PP having a foaming ratio of 20 times also showed a Shore C hardness of more than 45 and a wear score of 5.2, which is lower than that of the other examples. Therefore, it was found that satisfying the condition of Shore C hardness of 45 or less is an important factor in increasing the fit of the cast of the present invention.
- the reason why the feeling of wearing is highly evaluated by applying the buffer pad of the present invention was found to be that the buffer pad relieves the hard or unnatural texture that is applied when the cast surface is in direct contact with the skin.
