Problems solved by technology

However, the material of the carpet is very easy to breed bacteria and attract dust, stains and animal hair. If it is not cleaned properly, it will directly affect the indoor environment and our mood.
Self-cleaning products prepared by conventional processes usually use methods such as coating, and the duration of the effect is short, and the cleaning agent is prone to failure

Abstract

The invention relates to a method for preparing a self-cleaning plastic carpet, which belongs to the technical field of a novel material. The method combines two materials of nano titanium dioxide andchitosan which can synergistically achieve the double-effect sterilization effect; after treatment with an acid solution and a surface modifier, nano-titanium dioxide has hydrophobicity and improvedanti-pollution ability, and at the same time, titanium dioxide has strong photocatalytic ability and can play a certain self-cleaning effect; the method adopts half carbon fiber to replace the original fiber to prepare the carpet, improves the strength of the carpet, utilizes the conductivity of the carbon fiber to diffuse and release the static electricity on the surface of the carpet, reduces the adsorption force on the dust and hair, and facilitates the cleaning. The self-cleaning plastic carpet prepared by the invention has strong self-cleaning ability, can inhibit bacteria and kill bacteria, has no electrostatic adsorption for dust, stains and animal hair, and is hydrophobic and convenient to use.

Description

technical field [0001] The invention relates to a preparation method of a self-cleaning plastic carpet, which belongs to the technical field of new materials. Background technique [0002] In recent years, the phenomenon of superhydrophobicity on the surface of plant leaves has attracted people's attention. The so-called superhydrophobic ability of plants means that the leaves of plants have significant hydrophobicity, desorption, anti-sticking, self-cleaning functions, etc. The reason why the lotus "comes out of the mud without being stained" is because its surface has a layer of super-hydrophobic film, which can make it have the function of self-cleaning. Scientists observed the surface of the super-hydrophobic lotus leaf and found that the micro-nano double structure on the surface of the lotus leaf is the root cause of the super-hydrophobicity of the surface of the lotus leaf. Not only on the lotus, but also on the feet of insects. For example, water striders and mosq...
