Problems solved by technology

The dense cement mortar structure prevents light from reaching the interior of the cement mortar through the surface layer, and excites the luminescent material to absorb light. Similarly, the luminescent material cannot emit light through the surface layer of the cement mortar, resulting in most of the luminescent materials being unable to play their role; at the same time, cement is Black particles, darker in color, which have the effect of absorbing and blocking the light of luminescent materials
Therefore, based on the above reasons, the luminous brightness and luminous afterglow time of luminous cement mortar products cannot be solved.

Abstract

The invention discloses a luminous geopolymer mortar for building exterior walls, which comprises the following raw materials in parts by mass: 20-30 parts of metakaolin, 30-50 parts of alkali activator, 10-15 parts of luminescent powder, and 20-30 parts of glass sand 10-15 parts of glass powder, 1-3 parts of glass fiber and 6.7-13.6 parts of mixing aids. A luminescent geopolymer mortar for building exterior walls proposed by this technical solution is beneficial to improving the luminous intensity of the luminescent geopolymer mortar and prolonging the afterglow time, and at the same time can effectively ensure that the luminescent geopolymer mortar has better tensile strength. Strength, to overcome the deficiencies in the prior art.

Description

technical field [0001] The invention relates to the technical field of geopolymer materials, in particular to a luminescent geopolymer mortar for building exterior walls. Background technique [0002] Mortar is a bonding substance used for bricklaying in buildings. It is also used for exterior wall painting and exterior wall decoration. It is composed of a certain proportion of sand and cementing materials plus water. It is also called mortar and mortar. Luminescent mortar refers to mixing luminescent material into the mortar, and absorbing and storing energy through the luminescent material under the illumination of the light source. When the light source is removed, the long-lasting luminescent material will slowly release light energy to achieve the effect of self-luminescence. [0003] The luminous mortars in the prior art are all luminous cement mortars. Luminescent cement mortar has a dense structure. Under the irradiation of light, only a small amount of luminescent ...
