Description

Accelerated Outdoor Weathering Test Equipment {Accelerated Outdoor Weathering Test Equipment}

The present invention relates to an outdoor acceleration test apparatus, and more particularly, to a test apparatus designed to continuously perform outdoor weather resistance tests of polymeric materials used outdoors not only during the day but also at night.

In general, an outdoor acceleration test device is a method of exposing a polymer material product such as plastic to the natural environment outdoors for a certain period of time, tracking the sun, or condensing and irradiating natural light over the entire spectral area to accelerate the aging rate. It is a device for testing the change of state due to deterioration.

1 shows a conventional example of such an outdoor exposure test apparatus, in which a base plate 1 is installed so as to form a certain angle with the ground by a support 2, and a sample to be tested on the base plate 1 ( 100) is fixedly installed and exposed to ultraviolet rays for a certain period of time to check the deterioration condition.

However, in the conventional outdoor exposure test apparatus described above, since the sample is exposed to ultraviolet rays only during the daytime and not ultraviolet rays during the night time, there is a problem that the duration of the test is inevitably increased.

In order to improve this problem, the outdoor acceleration test apparatus of Patent Application No. 10-2015-0138310 as shown in FIG. 2 was invented, but the outdoor acceleration test apparatus needs to change the direction of the sample depending on the day and night, but the structure is complicated. In addition, since the enclosure is blocked, the temperature inside the enclosure is excessively increased by the artificial light source lamp at night, so that the sample may be deformed.

3 to 8, the outdoor acceleration test apparatus 10 for testing the deterioration performance of polymeric materials used outdoors includes a sample seat 110, a fixed support 120, an enclosure 130, It includes a shielding member 132, a link member 140, a driving unit 150, and a base 160.

A sample is installed on the sample mounting table 110. When the sample mounting table 110 is installed in the square-shaped mounting frame 111 and the mounting frame 111 through which the central portion is penetrated, the support bar 112 and the support bar 112 to hold the sample slide 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 vertical movement of the support bar 112 may be included. When the central part of the seating frame 111 is penetrated, the wind can pass back and forth, so that the same test environment as the natural conditions can be created. The size of the seating portion can be changed by sliding the support bar 112 up and down according to the size of the sample and fixing it with a stopper 113. The support bar 112 may have a U-shaped cross section in which a groove is formed on a side surface.

On the other hand, the amount of radiant energy in the entire radiation area (280 ~ 3000 ㎚) and the ultraviolet region (280 ~ 400 ㎚) as shown in Fig. 4 at the center part or the sample mounting part of the sample mounting table 110 is individually measured. The first and second day four systems 115 and 116 may be mounted at positions close 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 may be installed.

The fixing support 120 is coupled to the sample receiving table 110 to fix and support the sample receiving table 110. For example, the fixed support 120 may be formed of a horizontal support (not shown) that reinforces the strength of the vertical support by connecting two vertical supports and two vertical supports coupled to each end of the sample receiving table. The vertical support may be fixedly coupled to the sample receiving table 110 so that the angle of the sample receiving table 110 does not change and only one angle is kept constant, or it is hinged to the sample receiving table 110 as necessary. It may be to be able to change the angle of the sample mounting table (110).

The enclosure 130 is provided with an artificial light source lamp 131 therein, and one surface is open to irradiate light to the sample through the open surface. The artificial light source lamp 131 may be a metal halide lamp that emits white light close to sunlight by putting a halogen compound in a mercury lamp. However, since it is not limited thereto, an Ultraviolet (UV) lamp, a Xenon lamp, or the like may be used.

On the other hand, although not shown, a silver foil layer may be provided on the inner wall surface of the enclosure 130 so as to internally reflect light emitted from the artificial light source lamp. In this case, since the radiation light emitted from the metal halide lamp can be reflected, the exposure effect due to the diffuse reflection of ultraviolet light can be improved.

When the shielding member 132 is coupled to be inserted and protruded into the housing and protruded, the space between the housing 130 and the sample receiving table 110 is shielded, and a ventilation hole is formed on the surface thereof. The shielding member 132 may have a rectangular cylindrical shape. In addition, since a ventilation hole is formed in the edge portion, there is no problem that the internal temperature rises due to the shield member 132 through the wind. Since the shielding member 132 is provided, it is possible to prevent damage to the sample by contacting the sample with insects or foreign substances. In addition, a cylinder may be connected to the shield member 132 so that the shield member 132 can be inserted and protruded into the enclosure.

Link member 140 is made of a pair of two, each one end is coupled to the enclosure 130, the other end is rotatably coupled to the fixed support 120, when the rotation in one direction is finished, the enclosure 130 is opened. Make it opposite to the additional sample. In this way, when the link member 140 has finished rotating in one direction, a horizontal member connecting the pair of link members 140 is further provided at one side of the enclosure 130 so that the open portion of the enclosure 130 faces the sample. However, when the horizontal member is further provided, the opening portion of the enclosure 130 may be made to face the sample by controlling the angle of the enclosure 130 to change due to its own weight.

The driving unit 150 provides rotational force to the link member 140. The driving unit 150 may include a drive motor (not shown) that generates rotational force and a gearbox (not shown) that amplifies rotational force from the drive motor. Thus, the link member 140 rotates with respect to the fixed support 120 to change the position of the enclosure 130.

On the base 160, the above-mentioned sample seat 110, the fixed support 120, the enclosure 130, the shield member 132, the link member 140, and the driving unit 150 are placed. The base 160 may be fixed to the floor or, although not shown, may be provided with a moving means such as a wheel so that the position of the outdoor acceleration test apparatus can be moved.

On the other hand, when the pair of link members 140 has finished rotating in the other direction, the enclosure 130 may contact the base 160 with an opening portion 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. Therefore, the life of the device is increased. In addition, since the opening portion of the enclosure 13 is placed toward the base 160, it is possible to prevent rainwater or insects from entering the enclosure 130 during the daytime.

In addition, a pair of wheels 133 are provided at the left and right of one corner of the enclosure 130, and a ramp 161 is installed on the base 160 to which the pair of wheels 133 abuts, so that the link member 140 is forward and backward. During rotation, the wheels 133 may move along the ramp 161. In this way, when the wheels 133 are formed to move along the slope 161, when the link member 161 is rotated so that the enclosure 130 comes into contact with the base 160, the enclosure 130 becomes the base 160 You can alleviate the shock from the.

On the other hand, although not shown, the outdoor acceleration test apparatus according to the present invention may be configured to track the sun. For example, the base 160 is configured to rotate around a vertical axis, and a solar sensor for detecting the position of the sun is provided on the sample mounting table 110, and the base 160 is adapted to the position of the sun detected by the solar sensor. ) Can be made of a structure in which it is rotated.

A method of using the outdoor acceleration test apparatus made as described above will be described with reference to FIG. 9.

First, a polymer material sample to be subjected to an outdoor accelerated weather resistance test is fixed to the sample mounting table 110. At this time, since the sample mounting table 110 is provided with a support bar 112 that can slide up and down, the size of the mounting portion can be adjusted according to the size of the sample. In addition, if the sample is placed in a fixed state on the sample mounting table 110 during the day, the sample is exposed to sunlight to perform a weather resistance test.

Meanwhile, at night, the link member 140 is rotated forward through the driving unit 150 so that the open portion of the enclosure 130 faces the sample. When the open portion of the enclosure 130 faces the sample, the artificial light source lamp 131 in the enclosure 130 is driven to continuously expose ultraviolet rays to the sample seated on the sample mounting table 110.

On the other hand, when the open part of the enclosure 130 faces the sample, the shielding member 132 coupled to be inserted and protruded into the enclosure protrudes from the enclosure 130 and between the enclosure 130 and the sample mounting table 110 It will block the space. Since the shielding member 132 is present, it is possible to prevent insects or foreign substances from contacting the sample, and since a ventilation hole is formed at the edge of the shielding member 132, the internal temperature rises due to the shielding member 132 Does not occur.

Then, when the daytime comes again, the link member 140 is rotated in reverse through the driving unit 150 so that the open portion of the enclosure 130 is brought into contact with the base 160 while facing the base 160. Thus, it is possible to prevent rainwater or insects from entering the enclosure 130 during the daytime. On the other hand, since a wheel is attached to one end of the housing 130 and a ramp 161 is provided on the base 160, the housing 130 does not collide with the base 160 and lands smoothly.

In this way, in the case of using the outdoor acceleration test apparatus according to the present invention, heat generated from the artificial light source lamp 131 is discharged to the outside through the opening of the sample mounting table 110 and the shielding member 132, so that there is no excessive temperature increase. Weather resistance test can be performed in the same environment as daytime conditions.

The present invention has been described with reference to the embodiments shown in the accompanying drawings, but these are only exemplary, and those of ordinary skill in the art can understand that various modifications and other equivalent embodiments are possible therefrom. There will be. Accordingly, the true scope of protection of the present invention should be determined only by the appended claims.
