Light permeable cement plate with self-cleaning function and preparation method thereof

Abstract

The invention discloses a light permeable cement plate with a self-cleaning function. The light permeable cement plate is composed of a precast light permeable resin unit used for light guiding, a self-compacted cement mortar base body used as a main body and a super-hydrophobic self-cleaning transparent coating used as a cover surface layer. The precast light permeable resin unit is integrally embedded in the self-compacted cement mortar base body. The contact surface of the precast light permeable resin unit and the self-compacted cement mortar base body needs to be brushed with an interfacemodifying agent to conduct interface enhancement. A preparation method of the light permeable cement plate with the self-cleaning function comprises four process steps of precasting the light permeable resin unit, carrying out interface enhancement through brushing, implanting the cement base body and painting the cover surface coating. The light permeable cement plate with the self-cleaning function has the functions of light transmitting and image developing, day lighting and energy saving and water draining and cleaning. The applying field of the light permeable cement plate with the self-cleaning function covers building design, underground day lighting, interior decoration and the like.

Description

technical field [0001] The invention belongs to the technical field of environment-friendly building materials, and in particular relates to a cement board with functions of light transmission and development, lighting and energy saving, hydrophobic cleaning and a preparation method thereof. Background technique [0002] At the beginning of the 21st century, breakthroughs were made in endowing cement-based materials with light-guiding functions, and then light-guiding cement-based materials gradually became a research hotspot. According to the category of light-guiding components, light-guiding cement-based materials are divided into two categories: fiber-optic light-guiding cement-based materials using optical fiber materials as light-guiding components and resin light-guiding cement-based materials using resin materials as light-guiding components. . [0003] The international patent "Building block comprising light transmitting fibers and method for producing the same" (...

AI Technical Summary

Problems solved by technology

[0007] The purpose of the present invention is to provide a method for preparing a light-transmitting cement board with a self-cleaning function, which solves the problem of frequent washing due to rainwater, dust and other pollutants adhering to the surface of the existing light-guiding cement-based materials during long-term use. Problems, to achieve self-cleaning and light-transmitting effects, eliminating the need for cleaning light-guiding cement-based materials, and effectively ensuring its light-transmitting performance
