Since the components of the embodiments of the present invention can be positioned in various orientations, the directional terminology is used for illustrative purposes, not limitation.

As shown in FIGS. 1 and 2, the flame retardancy measuring apparatus according to a preferred embodiment of the present invention includes a sample stage 130 for placing a sample for measuring flame resistance, A heater 110 mounted on the one side of the safety box 140 so as to face the sample and heating the sample to heat the sample 110; A first thermocouple 120 for contacting the sample and measuring the temperature, a second thermocouple 121 positioned away from the first thermocouple 120, And a hood 150.

3, the sample stage 130 includes a sample support 131 having a predetermined area for arranging the sample, a height adjuster 133 for adjusting the height of the sample support 131, A connection block 134 mounted on the height adjuster 133 and connected to a conveying guide bar 135 for horizontally moving the sample pedestal 131, (Not shown).

The sample holder 131 is disposed in close contact with one side of the sample on the upper side, and then the sample is fixed using the sample holder 132.

Here, the sample holder 132 is formed in the shape of a letter 'A' and is provided on the edge of the sample support 131, and preferably has at least two.

One side of the height adjuster 133 is mounted on the lower side of the sample pedestal 131.

The height adjuster 133 includes a handle capable of adjusting the height.

The height of the sample pedestal 131 is adjusted by the height adjuster 133 so that the distance between the sample placed on the sample pedestal 131 and the heater 110 is reduced, Thereby shortening the time taken to apply the sample.

The other side of the height adjuster 133 mounts the connecting block 134.

The connection block 134 connects the height adjuster 133 with the conveyance guide bar 135 having a predetermined length for horizontally moving the sample pedestal 131. The connection block 134 and the conveyance guide 134, The bar 135 is connected.

At this time, a fixing block 136 for limiting the movement while supporting the conveying guide bar 135 is installed inside the safety box 140.

The fixing block 136 is provided with a hole through which the conveying guide bar 135 can be inserted and removed, and the conveying guide bar 135 is inserted into the hole.

When the connecting block 134 is pulled as described above, the distance between the connecting block 134 and the fixing block 136 is increased according to the conveying guide bar 135 to move the sample pedestal 131, Since the sample can be placed outside the sample holder 140, it is easy to place or remove the sample in the sample holder 131, thereby improving the convenience of the user.

In addition, the connection block 134 can be pushed back to place the sample pedestal 131 at the same position as the heater 110.

Here, the fixing block 136 may include a driving unit (not shown) such as a bearing to automatically move the conveying guide bar 135.

The safety box 140 accommodating the sample stage 130 constructed as described above can be made of tempered glass on one side so that the sample stage 130 can be visually confirmed during the test and can be opened and closed, It is easy to dispose or remove the sample by exposing the sample support 131 of the sample holder 130 to the outside.

In addition, the safety box 140 serves to protect the user during the flammability test of the sample.

The heater 110 is mounted on the safety box 140 so as to face the sample placed on the sample support 131 of the sample stage 130.

At this time, the support box may be further constructed to mount the heater 110 to the safety box 140.

The heater 110 is formed in a plate shape and emits heat only in a predetermined direction. This allows heat to be applied to the sample more intensively than heaters that emit heat in various conventional aspects, thereby shortening the measurement time of the sample.

The first thermocouple 120 and the second thermocouple 121 are used to measure the temperature of the sample heated by the heater 110.

The first thermocouple 120 and the second thermocouple 121 are preferably embedded in the height adjuster 133 of the sample stage 130.

A part of the first thermocouple 120 is exposed to the sample pedestal 131 on which the height adjuster 133 is mounted. That is, the first thermocouple 120 is exposed on the upper side of the sample pedestal 131 and is in intimate contact with one surface of the sample.

The upper second thermocouple 121 is embedded in the height adjuster 133 and partially exposed to the outside so as to be brought into close contact with the other surface of the sample placed on the sample pedestal 131.

In other words, the first thermocouple 120 measures the temperature by contacting one surface of the sample, which is a position where heat is not directly applied to the heater 110 and heat is transmitted through the other surface of the sample, 2 thermocouple 121 contacts the other surface of the sample at a position where heat is directly applied by the heater 110 to measure the temperature.

The temperature of the first thermocouple 120 and the temperature of the second thermocouple 121 are measured and the thermal conductivity of the sample is calculated through the temperature change.

The thermal conductivity can be calculated through the first thermocouple 120 and the second thermocouple 121, and the error range relating to the flame retardancy grade can be greatly reduced.

A hood 150 for discharging smoke generated in a sample heated by the heater 110 is installed in the safety box 140.

The hood 150 may be installed above the safety box 140, which is opposed to the sample pedestal 131.

The flammability measuring apparatus 100 configured as described above is further driven by the temperature controller 200 and the controller 300, as shown in FIG.

The temperature controller 200 controls the temperature of the heater 110 for the flame resistance test and the controller 300 controls the flame retardance measuring apparatus 100.

In order to use the flame retardance measuring apparatus 100, a user first pulls the connection block 134 to expose the sample pedestal 131 to the outside. Thereafter, the sample to be tested is placed on the sample pedestal 131 and fixed with the sample holder 132, and then the connection block 134 is pushed back so that the sample pedestal 131 is positioned inside.

Thereafter, the heater 110 is driven through the temperature controller 200 and the controller 300, and then the temperature of the sample heated by the heater 110 is measured by the first thermocouple 120 and the first thermocouple 120 2 thermocouple (121).

The thermal conductivity is calculated at the temperature measured through the first thermocouple 120 and the second thermocouple 121 to specify the flame retardancy of the sample.

At this time, smoke generated during heating the sample while driving the heater 110 is discharged to the outside using the hood 150.

Therefore, the flame-resistance measuring apparatus 100 driven as described above intensively heats the sample of the product for testing the flame resistance with the plate-type heater 110, thereby shortening the measuring time, It is possible to arrange the sample before the flame resistance test or to remove the sample after the flame resistance test is finished by adjusting the position of the sample pedestal 131 where the sample for testing the flame resistance is disposed, The efficiency can be improved.

It is possible not only to measure the temperature at the position where heat is directly received through the first thermocouple 120 and the second thermocouple 121 in the sample being heated in the process of testing the flame retardancy of the product, It is possible to calculate the thermal conductivity by measuring the temperature of the position, thereby significantly reducing the error range relating to the flame retardancy grade.

The embodiments of the present invention described above and shown in the drawings should not be construed as limiting the technical idea of the present invention. The scope of protection of the present invention is limited only by the matters described in the claims, and those skilled in the art will be able to modify the technical idea of the present invention in various forms. Accordingly, such improvements and modifications will fall within the scope of the present invention if they are apparent to those of ordinary skill in the art.
