Negative ion glass door and window with sterilization and formaldehyde removal functions and preparation method thereof

Abstract

The invention discloses a negative ion glass door and window with sterilization and formaldehyde removal functions and a preparation method thereof. The negative ion glass door and window comprises a door and window frame body fixed to the inner side of a wall, a glass door and window sash is arranged on the inner side of the door and window frame body, the glass door and window sash comprises a metal frame and a glass block wrapped by the metal frame, limiting shafts are arranged at the upper end and the lower end of one side of the metal frame, limiting grooves corresponding to the limiting shafts are formed in the door and window frame body, and the inner surface of the glass block is provided with a negative ion film with the sterilization and formaldehyde removal functions. According to the negative ion glass door and window with the sterilization and formaldehyde removal functions and the preparation method, the inner surface of the glass door and window sash is provided with the negative ion film with the sterilization and formaldehyde removal functions, and therefore the glass door and window can release negative ions beneficial to human health and can further play a role in indoor sterilization and formaldehyde removal, the indoor living environment is improved, and the comfort of people is improved.

Description

technical field [0001] The invention relates to the field of green building materials, in particular to an anion glass door and window with the function of sterilizing and removing formaldehyde and a preparation method thereof. Background technique [0002] As the high airtightness of modern residences becomes stronger and stronger, indoor air is polluted by dust, various bacteria, viruses, building materials, furniture and other harmful chemicals emitted; especially infectious bacteria and viruses in hospital wards are also Spread and pollute the air, damage human health and affect people's daily life. Moreover, in order to ensure that the indoor light is bright, most of the existing doors and windows use glass. Glass is a kind of transparency, strength and hardness, but its sealing is too strong and cannot be ventilated. It is chemically inert and will not interact with organisms. The formaldehyde emitted by the furniture is easy to accumulate in the room. If the windows ...

Problems solved by technology

Moreover, in order to ensure that the indoor light is bright, most of the existing doors and windows use glass. Glass is a kind of transparency, strength and hardness, but its sealing is too strong and cannot be ventilated. It is chemically inert and will not interact with organisms. The formaldehyde emitted by the furniture is easy to accumulate in the room. If the windows are opened for ventilation and the air disinfection machine is used for disinfection and sterilization, the outdoor noise, inhalable particles (such as PM2.5) will enter the room, and at the same time, ultraviolet light and other factors will cause harm to the human body. The coexistence of man and machine cannot be realized indoors, which seriously affects the living environment of people and reduces the comfort of people.
