Problems solved by technology

This method has a certain waterproof and antifouling effect, but it cannot last for a long time. Generally, it can only last for about three years.
Moreover, the surface of GRC exterior wall components needs to be re-coated after comprehensive cleaning, which increases the maintenance cost of building exterior walls.

Embodiment 1

[0058] The GRC building components produced by the proportioning of Table 1, wherein kaolin powder (%) refers to kaolin powder is the wt% of cement amount, TiO2 (%) refers to titanium dioxide as the wt% of cement amount. Tensile Strength, Flexural Strength and NO x Methods for determining the rate of reduction are well known in the art. Self-cleaning ability is the time to test the disappearance of pollutants on the surface of GRC.

[0059] From the ratio listed in Table 1 and the characteristics of the produced GRC building components, it can be seen that the ability of GRC to reduce NOx increases with the increase of the content of titanium dioxide while the structural layer remains unchanged. At the same time the time required to remove red pigment from GRC building components is reduced. Under the same content of titanium dioxide, the fineness of quartz sand has little effect on the reduction rate of NOx and the time required to remove red pigment.

Abstract

The present invention discloses a GRC building member with functions of air purification and self-cleaning, and a manufacturing method thereof. The GRC building member comprises an absorption layer and a structure layer, wherein the absorption layer is attached to the outer side of the structure layer, and comprises cement, aggregate, nanometer titanium dioxide, kaolin powder and filling fine powder, and the structure layer comprises cement, aggregate and glass fiber. The manufacturing method comprises: 1) uniformly mixing and stirring the components and the water for preparing the absorption layer according to a certain ratio; 2) uniformly mixing and stirring the components and the water for preparing the structure layer according to a certain ratio; and 3) molding a GRC reinforcement skeleton layer through mechanical spraying, premixing, lapping grouting and mixing method and then molding the absorption layer, or sequentially molding the absorption layer and the structure layer in a model, and then carrying out acid washing or sanding or polishing on the surface of the absorption layer. According to the present invention, based on the titanium dioxide photocatalysis principle, the product has the functions of the original GRC building member, and further has the functions of toxic gas absorption and surface self-cleaning.

Description

technical field [0001] The invention relates to the technical field of building concrete materials, in particular to an air-purifying and self-cleaning GRC building component and a manufacturing method thereof. Background technique [0002] Prefabricated GRC building products, including building exterior wall decoration and maintenance components (ie, exterior wall panels) used alone by GRC, various architectural shapes, decorative columns, lines, window covers, door covers, balcony railings, fountain decorations, sculptures, architectural sketches ; and various products of GRC combined with prefabricated or cast-in-place reinforced concrete components (such as GRC as a decorative or non-decorative permanent formwork for concrete structures or components), which are widely used in various residential or commercial buildings, large-scale comprehensive construction, and capital works. [0003] The main materials of the above prefabricated GRC building products include alkali-...
