FIG.

3 to 8, an outdoor promotion testing apparatus 10 for testing deterioration performance of a polymer material component used outdoors includes a sample placement table 110, a fixed support 120, a housing 130, A shielding member 132, a link member 140, a driving unit 150, and a base 160.

A sample is placed on the sample mounting table (110). The sample placing platform 110 includes a rectangular mounting frame 111 through which a central portion passes, a support bar 112 installed on the mounting frame 111 for holding a sample, and a support bar 112 sliding up and down A guide groove 114 serving as a guide and a stopper 113 for fixing the position of the support bar 112 by preventing the support bar 112 from moving up and down. If the center portion of the seat frame 111 is penetrated, the wind can pass back and forth, so that a test environment identical to a natural condition can be created. The size of the seat part can be changed by sliding the support bar 112 up and down in accordance with the size of the sample and fixing it with the stopper 113. [ The supporting bar 112 may have a U-shaped cross section with a side groove formed therein.

4, the amount of radiant energy in the entire radiation region (280 to 3000 nm) and the ultraviolet region (280 to 400 nm) is separately measured at the center portion or the sample seating portion of the sample mounting table 110 The first and

second sunrays

115 and 116 may be mounted adjacent to each other. In addition, a black panel thermometer 117 for measuring the surface temperature of the sample mounting table and a hygrometer 118 for measuring humidity can be provided.

The fixed support 120 is coupled to the sample placement table 110 to support and support the sample placement table 110. For example, the stationary support 120 may comprise two vertical supports coupled to each end of the sample seat and two horizontal supports (not shown) to reinforce the strength of the vertical support. The vertical support may be fixedly coupled to the sample placement table 110 so that the angle of the sample placement table 110 is not changed but only one angle is constant. The vertical placement support may be hinged to the sample placement table 110, It may be possible to change the angle of the sample placement table 110.

The enclosure 130 is provided with an artificial light source lamp 131 therein and irradiates light to the specimen through one opened surface thereof. The artificial light source lamp 131 may be a metal halide lamp that puts a halogen compound in a mercury lamp and emits white light similar to sunlight. However, UV lamps such as ultraviolet (UV) lamps, Xenon lamps, and the like may be used.

Although not shown, an inner surface of the housing 130 may be provided with an embossed layer to reflect light emitted from the artificial light source lamp. In this case, since the reflection of the radiation radiated from the metal halide lamp can be performed, the exposure effect due to the diffuse reflection of ultraviolet light can be improved.

When the shielding member 132 is inserted into the housing and protrudes from the housing to protrude, the space between the housing 130 and the sample mount 110 is shielded and a ventilation hole is formed on the surface. The shielding member 132 may have a rectangular tubular shape. Since the ventilation hole is formed in the rim portion, there is no problem that the temperature of the inside rises due to the wind due to the shielding member 132. The shielding member 132 can prevent insects or foreign matter from contacting the sample and damaging the sample. A cylinder may be connected to the shielding member 132 so that the shielding member 132 can be inserted into and protruded from the enclosure.

One end of the link member 140 is coupled to the housing 130 and the other end of the link member 140 is rotatably coupled to the fixed support 120. When the rotation of the link member 140 is completed in one direction, To face the additional sample. When the link member 140 is rotated in one direction, a horizontal member connecting the pair of link members 140 is provided on one side of the housing 130 so that the opening portion of the housing 130 faces the sample. When the horizontal member is further provided, it is possible to control the angle of the housing 130 by its own weight so that the opening of the housing 130 is opposed to the sample.

The driving unit 150 provides rotational force to the link member 140. The driving unit 150 may include a driving motor (not shown) for generating a rotational force and a gear box (not shown) for amplifying a rotational force generated from the driving motor. Thus, the link member 140 rotates about the fixed support 120 and the position of the housing 130 is changed.

The base station 160 includes the sample mount 110, the stationary support 120, the housing 130, the shielding member 132, the link member 140, and the drive unit 150 described above. The base 160 may be fixed to the floor or may be provided with a moving means such as a wheel, although not shown, so as to move the position of the outdoor promotion testing device.

On the other hand, when the pair of link members 140 are rotated in the other direction, the housing 130 can come into contact with the base 160 toward the opening 160 toward the base 160. In this case, since the housing 130 is placed in a stable state, unnecessary stress is not applied to the link member 140 connected to the housing 130 and the like. Thus, the lifetime of the device is increased. In addition, since the opening portion of the housing 13 is positioned toward the base 160, rainwater, insects, etc. can be prevented from entering the housing 130 during the daytime.

A pair of wheels 133 are provided on the left and right sides of the housing 130 and a base 160 on which the pair of wheels 133 abuts is provided with an inclined plate 161, The wheels 133 can be moved along the ramp 161 during rotation. When the wheels 133 are formed to move on the inclined platform 161, when the link member 161 rotates and the enclosure 130 comes into contact with the base 160, the enclosure 130 contacts the base 160, It is possible to mitigate the impact from the impact.

On the other hand, although not shown, the outdoor promotion test apparatus according to the present invention may be configured to track the sun. For example, the base 160 is configured to be rotatable about a vertical axis, and a sample mount table 110 is provided with a sun sensor for detecting the position of the sun, May be rotated.

A method of using the outdoor promotion test apparatus constructed as described above will be described with reference to FIG.

First, a sample of a polymer material to be subjected to an outdoor accelerated weathering test is fixed to the sample mounting table 110. At this time, since the sample support pedestal 110 is provided with the support bar 112 which can slide up and down, the size of the placement part can be adjusted according to the size of the sample. In the daytime, if the sample is placed in a fixed position on the sample seat 110, the sample is exposed to the sunlight and the weather resistance test is performed.

On the other hand, at night, the link member 140 is rotated in a forward direction through the driving unit 150 so that the opening of the housing 130 faces the sample. When the opening of the housing 130 is opposed to the sample, the artificial light source lamp 131 in the housing 130 is driven to continuously expose the ultraviolet light to the sample placed on the sample mounting table 110.

When the opening portion of the housing 130 is opposed to the sample, a shielding member 132 inserted into and protrudingly engaged with the housing protrudes from the housing 130 so that the gap between the housing 130 and the sample mounting platform 110 Thereby shielding the space. Since the shielding member 132 prevents insects or foreign matter from contacting the specimen and the ventilation hole is formed at the rim of the shielding member 132, the problem of the internal temperature rise due to the shielding member 132 .

The link member 140 is reversely rotated through the driving unit 150 so that the opening portion of the housing 130 abuts against the base 160 facing the base 160. [ Thus, it is possible to prevent rainwater or insects from entering the enclosure 130 during the daytime. The housing 130 has a wheel at one end thereof and the base 160 is provided with the inclined pole 161 so that the housing 130 is smoothly landed on the base 160 without colliding with the base 160 hardly.

When the outdoor stimulation testing apparatus according to the present invention is used as described above, heat generated from the artificial light source lamp 131 is discharged to the outside through the opening of the sample placing table 110 and the shielding member 132, It is possible to carry out the weathering test under the same conditions as the daytime conditions.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art. There will be. Accordingly, the true scope of protection of the present invention should be determined only by the appended claims.
