Test device and method for simulating ageing of building material under ultraviolet irradiation condition

The invention discloses a test device and method for simulating ageing of a building material under the ultraviolet irradiation condition. The device comprises an ultraviolet high-voltage mercury lampand an oval reflecting cover, wherein the wavelength of the ultraviolet high-voltage mercury lamp ranges from 315 nm to 420 nm, the ultraviolet high-voltage mercury lamp is connected with a rectifierand a trigger and arranged in the focus position of the oval reflecting cover, a test piece for a test is arranged below the ultraviolet high-voltage mercury lamp, and an aluminum alloy hollowed-outcushion plate and a solid cushion block are arranged sequentially arranged at the lower part of the test piece. The invention aims to scientifically, conveniently, accurately and regularly research the ageing problem of the building material under the ultraviolet irradiation condition. 本发明公开了模拟紫外线照射条件下建筑材料老化的试验装置及方法，装置包括紫外线高压汞灯和椭圆形反光罩，所述紫外线高压汞灯的波长范围为315～420nm，紫外线高压汞灯与整流器和触发器相连，紫外线高压汞灯设置在所述椭圆形反光罩的焦点位置，试件下方设置用于试验的试件，试件下部依次设有铝
