Abstract

The invention relates to a Rayleigh scattering PMMA plate, which comprises a transparent polymethyl methacrylate matrix and nano oxide particles uniformly distributed in the transparent polymethyl methacrylate matrix, and the diameter of the nano oxide particles is 5-100 nm. According to the Rayleigh scattering PMMA plate provided by the invention, when a light source passes through the prepared PMMA plate, Rayleigh scattering is formed, so that the effects of diffusing blue sky and simulating sunlight are realized; the preparation method of the Rayleigh scattering PMMA plate is simple in process, conditions are easy to realize, the Rayleigh scattering PMMA plate is convenient to efficiently prepare, and the application value is high.

Description

technical field [0001] The invention relates to the technical field of PMMA plates, in particular to a Rayleigh scattering PMMA plate and a preparation method thereof. Background technique [0002] Currently, research shows that people perform better and feel more comfortable in indoor environments with daylight. Daylight exposure reduces people's work stress and negative impact, enhances well-being and productivity, and in the long run, improves the physical and mental health of those who live indoors. [0003] However, some indoor places cannot allow sunlight to come in due to certain factors. At this time, creating a virtual sun and diffuse blue sky can be installed in offices, meeting rooms, underground shopping malls and other places without natural ambient light. In addition, when there is no outside Many closed offices and rooms look claustrophobic and depressing when there is a clear view, and there are many patents reporting Rayleigh scattering sunlight lamps.
