Problems solved by technology

[0003] However, in practical applications, the shortcomings of existing elevators can still be found. As we all know, elevators as public facilities serve many people every day. Sanitation problems are a major problem. The use of vertical elevators requires users to press Corresponding to the floor button, the vertical elevator ride is realized, but the floor button is touched by various people every day, and the bacteria on the surface can be imagined. The existing technology can only rely on regular wiping to solve this problem, and the work efficiency is extremely low; in addition, Due to the many gaps in ordinary elevators, they are vulnerable to fire and fire, and their front rooms and cars do not have the ability to prevent fire, waterproof, and isolate smoke. When a fire occurs, it is easy to cause safety accidents

Abstract

The invention discloses a flame-retardant antibacterial coating for an elevator and a preparation method of the coating. According to the invention, the coating is prepared from sodium diacetate, triphenyl phosphate, aluminum phosphide, nano modified bamboo charcoal, nano zinc oxide, potassium sorbate, graphite fiber, PVC resin, aluminum hydroxide powder, magnesium hydroxide powder, aluminum oxidepowder, quicklime powder, paraffin, sodium tetraborate, pine-soot ink, carbon tetrachloride, terpilenol, dodecyl glucoside, ethoxyquinoline and polyhexamethylene biguanidine hydrochloride through thesteps of mixing, calcining, ultrasonic dispersion and curing. Tests show that the coating prepared by the invention has excellent flame-retardant and antibacterial effects.

Description

technical field [0001] The invention relates to a flame-retardant and antibacterial coating for elevators, belonging to the technical field of building elevators. Background technique [0002] Elevator is a kind of vertical elevator powered by electric motor, equipped with box-shaped gondola, used for multi-storey buildings to take advantage of people or carry goods. There is also a step type, and the tread plate is installed on the crawler belt to run continuously, commonly known as an escalator or a moving walk. Fixed lifting equipment serving specified floors. A vertical elevator has a car running between at least two vertical or inclination angles of less than 15° rigid guide rails. The size and structure of the car are convenient for passengers to enter and exit or to load and unload goods. It is customary to use elevator as a general term for vertical transportation in buildings regardless of its driving mode. During the use of these elevators, it is necessary to t...
