A protective glass that reduces sunlight energy

Abstract

The invention relates to the technical field of glass, in particular to a piece of protection glass capable of reducing sunshine energy. The piece of protection glass is prepared from the following components in parts by mass: 100 parts of polymethyl methacrylate, 0.5 to 1 part of nano-zinc oxide, 0.1 to 0.5 part of modified or non-modified melanin, 0.1 to 0.3 part of samarium methacrylate, 0.5 to 1 part of sodium alga acid, 0.3 to 0.6 part of stearic acid and 0.3 to 0.5 part of methacrylic acid. The protection glass can effectively reduce energy of sunshine, mainly reducing blue rays in visible light and ultraviolet rays in invisible light, so that harms to people due to the sunshine can be effectively avoided.

Description

technical field [0001] The invention relates to the technical field of glass, in particular to a protective glass for reducing sunlight energy. Background technique [0002] Sunlight is the most important natural light source. It illuminates the earth and makes the whole world colorful and colorful. When the light changes with the passage of time and the weather, it will directly affect the color of the object image. Sunlight is the light emitted by the "burning" of the nuclear reaction on the sun. It shoots to the earth through a long distance, and then reaches the ground after being filtered by the atmosphere. Its energy distribution in the visible spectrum is uniform, so it is white light. Sunlight is an electromagnetic wave, divided into visible light and invisible light. Visible light refers to what can be seen by the naked eye, such as red, orange, yellow, green, blue, indigo, and purple in the sun's brilliant seven-color rainbow light; invisible light refers to what...

Problems solved by technology

[0003] Although sunlight gives us energy, the ultraviolet light and blue light in the light will bring unnecessary troubles to people's bodies and lives. In order to reduce the excessive negative impact of sunlight on people, a glass that can Reduce the energy of sunlight, and selectively reduce the energy of sunlight, so as to be more conducive to people's life needs
