Problems solved by technology

Among them, PVC film is widely used. However, these films are usually exposed to the sun as pool decoration materials, resulting in poor film stability.
The water in the swimming pool contains hypochlorite, which is also easy to corrode and penetrate the membrane material, which further leads to the aging, discoloration, and even pulverization of the membrane material, which makes the pool decoration materials need to be replaced frequently
In addition, various molds are easy to grow in the open-air swimming pool, which makes the surface of the membrane easy to grow mold and affects the normal use of the swimming pool.

Abstract

The invention belongs to the technical field of materials, and discloses a chlorine-permeation-resistant and mildew-proof film and a preparation method and application thereof. The film is prepared from the following raw material components: resin, graphene oxide, carbon nanotubes, nano zinc oxide and a coupling agent. Due to the coupling agent, the graphene oxide, the carbon nanotubes and the nano-zinc oxide can be uniformly dispersed in the resin, so that the effects of the graphene oxide, the carbon nanotubes and the nano-zinc oxide are exerted, and the chlorine permeation resistance of the prepared membrane can be remarkably improved due to the coexistence of the graphene oxide, the carbon nanotubes and the nano-zinc oxide; nano-zinc oxide not only has anti-ultraviolet, anti-infrared, sterilizing and mildew-proof effects, but also interacts with the one-dimensional carbon nanotubes and the two-dimensional graphene oxide, so that the chlorine penetration resistance of the film is improved, and the mechanical property of the film can be improved. The film has good chlorine penetration resistance, is good in stability in illumination and water containing pypocholoride, and is not liable to discolor and age.

Description

technical field [0001] The invention belongs to the technical field of materials, and in particular relates to a chlorine permeation-resistant and mildew-proof film and its preparation method and application. Background technique [0002] Traditional pools are decorated with ceramic tiles, which have certain safety hazards. For example, the tiles are too hard and easy to be bruised; there may be a small amount of radioactive substances in the tiles, which also have certain potential harm to the human body. Therefore, in the prior art, some film materials have been adopted as the decorative materials of the pool, such as PVC (polyvinyl chloride) film, PE (polyethylene) film, and EVA (ethylene-vinyl acetate) film. Among them, PVC film is widely used. However, these films are usually exposed to the sun as pool decoration materials, resulting in poor stability of the film material. The water in the swimming pool contains hypochlorite, which is also easy to corrode and penetrate...
