Abstract

The invention relates to a low-energy-consumption artificial weathering aging device which comprises a sample placing frame and a radiation source which are coaxially arranged, wherein the sample placing frame and the radiation source are in an inverted semi-cone shape, a gap is formed between the sample placing frame and the radiation source, and the radiation source is rotatably arranged in the sample placing frame; the radiation source comprises a rotating shaft, a supporting base and a lamp panel, the supporting base is fixed on the rotating shaft, and the lamp panel is arranged on the outer side surface of the supporting base; the lamp panel comprises a substrate and an LED light source mounted on the substrate; and the LED light source at least comprises a plurality of ultraviolet LED lamps, the plurality of ultraviolet LED lamps have different wavelengths, and the plurality of ultraviolet LED lamps form ultraviolet spectrum components similar to that in solar radiation. The low-energy-consumption artificial weathering aging device is simple in structure, low in energy consumption and long in service life, can simulate various test environments at the same time, and can effectively reduce the detection cost.

Description

technical field [0001] The invention belongs to the technical field of artificial weather aging equipment, and in particular relates to a low energy consumption artificial weather aging device. Background technique [0002] Light, heat, water and oxidation are several important factors that cause material aging. In order to evaluate the performance of materials, artificial weather aging tests are usually used to evaluate the life of materials. The artificial climate aging test is an artificial accelerated aging test method that simultaneously simulates and strengthens factors such as light, heat, humidity and rainfall in the atmospheric environment in a closed environment (such as a test chamber). [0003] Studies have shown that light is the most important factor leading to material aging; most of the research objects in artificial weathering tests are polymer materials, and the performance degradation of these materials is mainly caused by photochemical reactions caused by...
