Problems solved by technology

However, there are also some problems to be solved in the above applications, such as the substrate attached to the self-cleaning photocatalytic material is not strong enough (such as peeling off the surface of the stone), or there are some problems in the weather resistance (such as poor UV resistance of the coating), etc., resulting in its durability. Insufficient sex, usually loses its effect after 3-5 years

Embodiment 1

[0027] The ultra-high-performance concrete decorative hanging board with high-efficiency self-cleaning photocatalytic function is prepared by the process of the following steps:

[0028] 1. Use PVC wood-plastic formwork to make the mold, and clean the dust on the surface of the mold;

[0029] 2. Apply solvent-based surface retarder on the surface of the mold, the model is RECKLI CR TYPE N / 02, and the dosage is 200g / m 2 , enter the next process after the surface is dry;

[0030] 3. Put the UHPC dry mixture into the mixer and add water (UHPC is a commonly used UHPC material in the market, its compressive strength is 100-150MPa, and the maximum particle size of its aggregate is not more than 1mm, the same below) and stir until the slurry becomes fluid , add glass fiber in an amount of 0.7% of the volume of UHPC, and stir evenly;

[0031] 4. Pour the stirred UHPC material into the mold, and pave and smooth the surface;

[0032] 5. Maintain the UHPC until the compressive strengt...

Embodiment 2

[0037] The ultra-high-performance concrete decorative hanging board with high-efficiency self-cleaning photocatalytic function is prepared by the process of the following steps:

[0038] 1. Use steel formwork to make the mold, and clean the dust on the surface of the mold;

[0039] 2. Spray a solvent-based surface retarder on the surface of the mold, the model is RECKLI CR TYPE N / 02, and the dosage is 200g / m 2 , enter the next process after the surface is dry;

[0040] 3. Put the UHPC dry mixture into the mixer and add water to stir. After the slurry becomes fluid, add basalt fiber in an amount of 1.3% of the volume of UHPC, and stir evenly;

[0041] 4. Pour the stirred UHPC material into the mold, and pave and smooth the surface;

[0042] 5. Maintain the UHPC until the compressive strength reaches 48MPa before demoulding, and rinse the mold surface of the UHPC board with a high-pressure water gun, and rinse off the cement paste that has contacted the retarder on the surface...

Abstract

The invention belongs to the technical field of building decoration, and particularly relates to an ultra-high-performance concrete decorating hanging board with a self-cleaning photocatalysis function and a manufacturing technology thereof. The technology takes ultra-high-performance concrete as base material of the decorating hanging board, gravel aggregate is exposed on the surface of the ultra-high-performance concrete through a surface-aggregate-exposing technology to obtain a rough surface, and then self-cleaning photocatalysis material is sprayed to the rough surface to obtain the ultra-high-performance concrete decorating hanging board with the self-cleaning photocatalysis function. The ultra-high-performance concrete decorating hanging board with the high-efficiency self-cleaning photocatalysis function can promote the reaction efficiency of the self-cleaning photocatalysis material greatly and enable the self-cleaning photocatalysis material adhering to the surface of the decorating hanging board to achieve a high durability.

Description

technical field [0001] The invention belongs to the technical field of architectural decoration, in particular to an ultra-high-performance concrete decorative hanging board with self-cleaning photocatalytic function and a manufacturing process thereof. Background technique [0002] With the pollution of urban air environment becoming more and more serious, the decoration materials of building exterior walls have been greatly affected. Due to poor surface stain resistance of some stone curtain walls and exterior wall veneers, polluted air directly affects their aesthetic durability, resulting in increased cleaning and maintenance burdens in the future. At present, photocatalytic self-cleaning materials are used on the exterior walls of some high-end buildings to solve this problem. For example, after using photocatalytic self-cleaning materials for stone curtain walls and decorative hanging panels, their surface pollution resistance is greatly enhanced. It also has a posit...
