Problems solved by technology

It can be seen from the above prior art that the light-transmitting resin-based light-guiding cement-based material is a method of preparing the resin light-guiding cement-based material by prefabricating the light-transmitting resin unit and then implanting it into the cement matrix, but the resin light-guiding cement-based material The self-compacting cement in the material is easy to accumulate various organic and inorganic stains after being used for a long time, which not only affects the light transmission performance of the resin light-guiding cement-based material, but also affects the appearance of the building, and is also difficult to clean. Therefore, the preparation has a self-cleaning function The resin light guide cement-based material is very necessary

Abstract

The invention provides a light-transmitting resin type light guide cement material containing a superhydrophobic titanium dioxide thin film, and a preparation method of the light-transmitting resin type light guide cement material. The light-transmitting resin type light guide cement material containing the superhydrophobic titanium dioxide thin film comprises an interface enhanced light-transmitting resin type light guide cement base material and the superhydrophobic titanium dioxide thin film. The preparation method comprises the following steps: evenly coating the surface of a light-transmitting resin unit with a coupling agent, transferring into a mould, adding self-compacted cement mortar, hardening and removing the mould, polishing and grinding to obtain the interface enhanced light-transmitting resin type light guide cement base material; spraying the surface of the interface enhanced light-transmitting resin type light guide cement base material with a nano titanium dioxide photosensitive solution, drying, carrying out twice exposure, then washing the surface of the material with a solvent, and carrying out heat treatment so as to obtain the light-transmitting resin type light guide cement material containing the superhydrophobic titanium dioxide thin film. The light guide cement material prepared by the invention has the effects of light transmitting and developing aswell as lighting and energy saving, and also has functions of draining off water and self-cleaning, thus being capable of being applied to the fields such as building design, underground lighting andindoor devices.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a light-transmitting resin-type light-guiding cement material containing a superhydrophobic titanium dioxide film and a preparation method thereof. Background technique [0002] With the advancement of my country's urbanization process, urban construction land resources are increasingly scarce, making new buildings tend to develop in the direction of super high-rise and high density. Mutual shading among buildings will inevitably affect the natural lighting of the building, especially the giant buildings and the shady side of the building. The indoors are dark and gloomy all day long. The only way to increase the lighting level is to increase the lighting level by adding artificial lighting, which makes the lighting conditions of people's residences poor and cannot be guaranteed. Adequate light time. Because concrete does not have light-transmitting proper...
