Description

Other Material Heat Insulation Gasket for Windows and Doors Frame}

The present invention relates to an insulating gasket for a high-productivity window frame, and in particular, a different quality for a window frame that enables a gasket of a desired hardness to be integrally molded into an insulating gasket used to improve thermal insulation by being coupled to an aluminum window frame. It relates to material insulation gaskets.

As is well known, windows must satisfy not only the function of preventing rain and wind, but also functions such as insulation, sound insulation, wind pressure, airtightness, and watertightness of the building.

As a means of insulation for this, Korean Utility Model Publication No. 2012-0010116 (name of the draft: soundproof and airtight gasket for windows and doors; hereinafter referred to as'cited invention 1') can be found. This cited invention 1 is used to seal the space between the window frame and the window as shown in FIG. In more detail with reference to FIG. 1, the support 12 is provided with a fixing body 11 that is inserted and fixed in the fixing groove of the window frame and is provided at the center of the fixing body 11 and has an upward length. Equipped. In addition, a linear contact portion 13 that is double-extruded from a material different from the support 12 is provided on the upper end of the support 12. At this time, the fixture 11 and the support 12 are molded from a hard material, and the contact portion 13 is molded from foam rubber. On the other hand, in order to prevent the contact part 13 of the foam rubber from being damaged or worn due to friction, a coating part 13A capable of protecting the outer circumferential surface while maintaining its own elasticity is further provided. This coating portion (13A) is formed of a silicone coating.

In addition, a look at Korean Patent Laid-Open Publication No. 10-2012-0043536 (name of the invention: gasket for windows and doors with improved structure and function; hereinafter referred to as “cited invention 2”) citing cited invention 1 as a known technology, which is shown in FIG. In the gasket for a window sealing the space between the window frame and the window as described above, the fixing part 1 having the same length and width as the fixing groove, which is fitted and fixed in a fixing groove formed in a lengthwise direction on the window frame or the window, A sealing functional part (2) having a length equal to the length of the fixing part (1), extending upwardly perpendicular to the width of the fixing part (1), and having a width of a side profile curved toward one side, and It includes a surface portion (3) formed on the convex surface of the sealing functional portion (2),

The fixing part 1 is made of a hard synthetic resin material, the sealing function part 2 is made of a soft rubber material, and the surface part 3 is made of a slip material.

According to the cited invention 1 and cited invention 2, a fixture (fixing part) is molded with a rigid synthetic resin material that is commonly bonded to the concave portion of a window and the adhesion part (sealing function part) is made of TPV (thermoplastic vulcanizate). You can see that it is molding.

On the other hand, the molding temperature of polyamide, which is used as a representative material of the fixture (fixed part), is 250℃ to 290℃, whereas the TPV, which is a material of the contact part (sealing function part), is 160℃ to 200℃, so the temperature difference is Severe, if the molding temperature at the time of double extrusion is adjusted to polyamide, TPV is carbonized and cannot be molded integrally. If the molding temperature is adjusted to TPV, the fixed body (fixed part) of the polyamide material may not be formed. There are many problems in that high-quality double extrusion molding becomes difficult.

In addition, since the TPV used as the material of the contact part (sealing function part) has a relatively high hardness of A65 or higher, especially at low temperatures, windproof and thermal insulation performance is poor, and thus, there is a problem that it does not meet the quality requirements of consumers.

1. Republic of Korea Utility Model Publication No. 2012-0010116 (name of the draft: gasket for soundproof and airtight prevention windows) 2. Republic of Korea Patent Publication 10-2012-0043536 (Name of invention: gasket for windows and doors with improved structure and function)

In order to solve this problem, the present invention has a solid adhesive state even though the material of the fixing body (fixing part) and the contact part (sealing function part) of the insulation gasket used in the window frame is a different material having a difference in molding temperature. The purpose of this is to provide an insulating gasket made of a heterogeneous material for a window frame by making it possible to obtain a complete and stable quality in shape.

The present invention is made of a rigid material such as polyamide, and a close contact portion (sealing function portion) of the heat insulating gasket used in the window frame to achieve this object (fixed portion; hereinafter referred to as "fixed portion"); Hereinafter, it will be described as "sealed part.") The material is TPV (thermoplastic vulcanizate), but made of olefin component TPE (Thermo Plastic Elastomer) having compatibility between the material of the fixing part and the material of the sealing part. In three extruders that each extrude the material of the fixing part, the material of the sealing part, and the material of the adhesion media layer by setting the temperature to mold the adhesive media layer, the molding temperature of the fixing part made of polyamide is 250 ℃ ~ 290 ℃, the molding temperature of the sealing part made of TPV (Thermoplastic Vulcanizates) is in the range of 160 ℃ ~ 200 ℃, the molding temperature of the TPE (Thermo Plastic Elastomer) adhesive media layer made of the olefin component is 160 ℃ In the range of ~ 250°C, the three materials are integrally extruded from one die through each extruder, and in particular, the adhesion is made with an olefin component compatible with the components of the fixing part and the sealing part. Despite the fact that the intermediate layer is integrally formed simultaneously by extruding it, it provides a wide range of temperature tolerance during extrusion, so that it is not carbonized and extruded and adhered integrally despite the significant difference in molding temperature between the fixed part and the sealed part. It can be.

In this way, the present invention does not carbonize when the fixing part, the sealing part, and the adhesive media layer are integrally molded despite the high-temperature molding temperature being different from each other, and it is firmly adhered, molded, and extruded in a complete shape. It is possible to provide an insulating gasket of a heterogeneous material of quality, and at the same time, by improving the sealing function of the sealing part by the additional flexibility given as the adhesive media layer is made of TPE material, it will provide the high level of windproof and insulation performance required by the consumer. There is a useful effect to be able to do.

Hereinafter, embodiments of the present invention will be described in detail so that those of ordinary skill in the art can easily implement the present invention with reference to the accompanying drawings.

A specific embodiment of the insulating gasket according to the present invention is shown in Figs. 3, 5, 7, 9.

The present invention as can be seen from this is composed of a fixed portion 100 having the function of an insulating bar and a sealing portion 200 performing the sealing function of the opening and closing portion,

The fixing part 100 is coupled to the inside of the window 600 as shown in the cross-sectional view of Figs. 4, 6, 8, and 10 to function as an insulating bar to minimize heat conduction inside and outside the window 600. As such, it can be manufactured with equipment as illustrated in FIG. 11.

In the insulating gasket of a different material for a window frame according to the present invention, the material of the fixing part 100, the material of the sealing part 200, and the material of the adhesive medium layer 300 bonding them are different, and these different materials are integrated. Is to be extruded.

To this end, in the present invention, as shown in FIG. 11, three hoppers 401 for inputting resins of different materials and an inlet are provided under the hopper 401, and are heated and transferred by a heater. Three extruders 400 equipped with a barrel 403 for extruding with a die 500 of one end after the resin is kneaded and melted while rotating the screw 402,

After passing through the designated passage of the dies 500 fixed to the extruder 400 to form a constant shape, it is solidified with an unillustrated cooling means supplied with cooling water, and is continuously picked up by a tensioning capstan. It produces products in the longitudinal direction.

In particular, in the present invention, three kinds of resins for molding the fixing part 100, the sealing part 200, and the adhesive media layer 300 reach the die 500 through each extruder 400, and It is extruded in an integrally bonded state at 500, and accordingly, an insulating gasket made of a different material for a window frame made of three types of materials can be molded.

In the present invention, polyamide (hereinafter referred to as'PA') may be used as the material of the fixing part 100.

As is well known, because PA has low thermal conductivity, it has excellent condensation prevention, airtightness and sound insulation effect, and has structural stability and durability, so it is combined with the window 600 as shown in Figs. 4, 6, 8, 10. Insulation performance is obtained.

In addition, the sealing portion 200 in the present invention is molded of TPV (Thermoplastic vulcanizates), which is a flexible material and is used as a gasket for sealing and soundproofing the window 600, as is known. , In particular, in the present invention, an adhesive medium layer 300 is placed between the fixing portion 100 and the sealing portion 200 to be bonded by an extrusion method, and the adhesive medium layer 300 is TPE (Thermo Plastic Since it is made of elastomer, it is composed of olefin components (components that are chemically compatible with PA, PP or TPV) that have the properties of rubber and PA.

Therefore, despite the fact that the resin of three materials is integrally molded and extruded by the facility as illustrated in FIG. 11, PA and PA, which are not compatible with each other by the adhesive media layer 300, TPV can be stably bonded and molded by TPE.

In addition, in the present invention, the molding temperature of the PA is 250°C to 290°C, whereas the molding temperature of TPV is 160°C to 200°C, so the difference in molding temperature is large. Accordingly, when extruding the two materials, the temperature difference at the bonding part between the materials is Therefore, if they are extruded by a double extrusion method according to each molding temperature, carbonization may occur along the interface of the TPV, resulting in poor adhesion of the sealing part 200,

If the molding temperature of the PA is lowered, the problem of the non-molding of the fixing part 100 made of PA is caused.

Therefore, in the present invention, the adhesive medium layer 300 is posted and extruded, and since the adhesive medium layer 300 is TPE, the molding temperature is in the range of 160°C to 250°C, and the fixing part ( 100) at the interface with PA or TPV, which is the sealing part 200, the same components are adhered to each other so that complete molding of all three materials is possible without carbonization. Looking at a specific embodiment of the present invention, as follows. same.

Example 1

In this embodiment, the molding temperature of the PA, which is the fixed part 100, is 270°C, the molding temperature of the TPV, which is the sealing part 200, is 180°C, and the TPE molding temperature, which is the adhesive medium layer 300, is 200°C. Was carried out,

At the interface between TPE and PA, carbonization was not observed even though the molding temperature of PA was 270℃, which was higher than the upper limit of TPE molding temperature of 250℃.

This result is due to the combination of the olefin component having the properties of PA among the components of the TPE and the PA material that is the fixing part 100, and the olefin component having the properties of the PA is considered to expand the high temperature tolerance of TPE.

In this example, the PA is completely molded, and at the interface between TPE and TPV, carbonization does not occur because the upper limit of the molding temperature range of TPV is 200°C, and TPV is also completely molded to obtain a product having a good shape.

Example 2

In this embodiment, the molding temperature of the PA as the fixed part 100 is set to 250°C, the molding temperature of the TPV as the sealing part 200 is set to 160°C, and the molding temperature of the TPE as the adhesive medium layer 300 is set to 160°C. Was carried out,

At the interface between TPE and PA, the molding temperature of TPE is the lower limit, and the upper molding temperature of TPE is 250℃, so there is no problem of carbonization, and at the interface between TPE and TPV, the lower limit of the molding temperature range of both materials is 160℃. It was confirmed that the complete molding was performed without causing the problem of.

Example 3

In this embodiment, the molding temperature of the PA, which is the fixed part 100, is set at 290° C., the molding temperature of the TPV, which is the sealing part 200, is set at 200° C., and the TPE molding temperature of the adhesive media layer 300 is set at 230° C. Was carried out,

At the TPE and PA interface, although the molding temperature of PA is the upper limit of 290℃, in reality, no carbonization problem occurred at the interface of TPE, and the carbonization problem at the interface of TPV even though the current molding temperature of TPE is 230℃. Did not occur. This result is due to the fact that the TPE component is an olefin component having the same properties as the PA component and forms the interface between PA and TPE and bonds it.

In addition, since the molding temperature of TPE is 230℃, it is higher than 200℃, which is the upper limit molding temperature of TPV, which is the sealing part 200, but the same component as TPV of TPE forms an interface and forms an adhesive layer to prevent carbonization of TPV, which is a problem of carbonization. Did not occur.

Accordingly, in Example 3, as the TPE expanded the temperature tolerance on both sides, stable adhesion was possible despite a significant difference in molding temperature, thereby preventing carbonization and obtaining a good quality product that did not cause unmolded problems. .

In addition, in another embodiment of the present invention, polyamide (PolyAmide; hereinafter referred to as'PA') is used as the material of the fixing part 100, and the sealing part 200 is molded with styrene ethylene butylene styrene (SEBS). It is also a kind of thermoplastic elastomer (TPE), so it is a flexible material, so it is used as a gasket for sealing and soundproofing the window 600.

In the present invention, even in this embodiment, the adhesive mediator layer 300 is placed between the fixing part 100 and the sealing part 200 to be adhered by an extrusion method. In this embodiment, the adhesive mediator layer 300 is Since it is made of TPE (Thermo Plastic Elastomer), it is composed of olefin components (components that are chemically compatible with PA, PP or TPV) that have the properties of SEBS rubber and PA.

Therefore, despite the fact that the resin of three materials is integrally molded and extruded by the facility as illustrated in FIG. 11, PA and PA, which are not compatible with each other by the adhesive media layer 300, SEBS can be stably bonded and molded by TPE.

In addition, in the present invention, the molding temperature of the PA is 250 ℃ ~ 290 ℃, whereas the molding temperature of SEBS is 180 ℃ ~ 210 ℃, the molding temperature difference is large. Accordingly, when extruding the two materials, the temperature difference between the materials is large. When these are extruded according to the respective molding temperatures by the double extrusion method, carbonization occurs along the interface of the SEBS, resulting in poor adhesion of the sealing part 200,

If the molding temperature of the PA is lowered, the problem of the non-molding of the fixing part 100 made of PA is caused.

Therefore, in the present invention, the adhesive media layer 300 is posted and extruded, and since the adhesive media layer 300 is TPE, the molding temperature is in the range of 160°C to 250°C, and the fixing part ( 100) at the interface with PA or SEBS, which is the sealing part 200, the same components are adhered to each other so that complete molding of all three materials is possible without carbonization. Looking at a specific embodiment of the present invention as follows. same.

Example 4

In this embodiment, the molding temperature of PA, which is the fixed part 100, is 270°C, the temperature of SEBS, which is the sealing part 200, is 180°C, and the molding temperature of TPE, which is the adhesive medium layer 300, is 200°C. Was carried out,

At the interface between TPE and PA, carbonization was not observed even though the molding temperature of PA was 270℃, which was higher than the upper limit of TPE molding temperature of 250℃.

This result is due to the combination of the olefin component having the properties of PA among the components of the TPE and the PA material that is the fixing part 100, and the olefin component having the properties of the PA is considered to expand the high temperature tolerance of TPE.

In this example, the PA is completely molded, and at the interface between TPE and SEBS, carbonization does not occur because the upper limit of the molding temperature range of SEBS is 210°C, and TPV is also completely molded to obtain a product having a good shape.

Example 5

In this embodiment, the molding temperature of PA as the fixed part 100 is set to 250°C, the temperature for forming SEBS as the sealing part 200 is set to 180°C, and the molding temperature of TPE as the adhesive media layer 300 is set to 160°C. Was carried out,

At the interface between TPE and PA, the molding temperature of TPE is the lower limit, and the upper molding temperature of TPE is 250℃, so there is no problem of carbonization. At the interface between TPE and SEBS, the lower limit of the molding temperature range of both materials is 180℃ and 160, respectively. Since it is °C, it was confirmed that complete molding was performed without causing the problem of unmolding.

Example 6

In this embodiment, the molding temperature of PA, which is the fixed part 100, is 290°C, the temperature of SEBS, which is the sealing part 200, is 200°C, and the molding temperature of TPE, which is the adhesive media layer 300, is 230°C. Was carried out,

At the TPE and PA interface, although the molding temperature of PA is the upper limit of 290℃, in reality, no carbonization problem occurred at the interface of TPE, and the carbonization problem at the interface of TPV even though the current molding temperature of TPE is 230℃. Did not occur. This result is due to the fact that the TPE component is an olefin component having the same properties as the PA component and forms the interface between PA and TPE and bonds it.

In addition, since the molding temperature of TPE is 230℃, it is higher than 210℃, which is the upper limit molding temperature of SEBS, which is the sealing part 200, but the same component of SEBS of TPE forms an adhesive layer at the interface to prevent carbonization of SEBS, resulting in carbonization problems. Did not do it.

Accordingly, in Example 6, as the TPE expanded the temperature tolerance of both sides, stable adhesion was possible despite a significant difference in molding temperature, thereby preventing carbonization and obtaining a product of good quality without causing the problem of unmolding. .

Comparative Example 1

In this comparative example, the molding temperature of the PA as the fixed part 100 is set to 250°C, the molding temperature of the TPV as the sealing part 200 is set to 150°C, and the TPE molding temperature as the adhesive medium layer 300 is set to 150°C. Extrusion was performed,

Except for the PA, which is the fixing part 100, both TPE and TPV did not completely melt the resin, so extrusion unmolding occurred. Accordingly, it was confirmed that the adhesive function of the materials was lost, resulting in poor adhesion.

Comparative Example 2

In this embodiment, the molding temperature of the PA as the fixing part 100 is set to 340°C, the molding temperature of the TPV as the sealing part 200 is set to 220°C, and the molding temperature of the TPE as the adhesive medium layer 300 is set to 240°C. Was carried out,

As the flow of PA increases, the shape control becomes unstable. At the interface between TPE and PA, the molding temperature of PA exceeds the upper limit of 340°C, causing a problem of sporadic carbonization at the interface with the TPE. Since the temperature is also higher than the upper limit temperature, the problem of sporadic carbonization occurs and the adhesion is poor, so the quality of the product is deteriorated.
