Abstract

The invention relates to a preparation method of a light-emitting water-permeable paving material. The reparation method of the light-emitting water-permeable paving material comprises the following steps: preparing a base layer, uniformly mixing cement, aggregates, water and a water reducer in a mass ratio of 1 to (4-5) to (0.25-0.45) to (0-0.2), and pressing; preparing a surface layer: uniformly mixing cement, aggregates, water, a toner and a water reducer in a mass ratio of 1 to (3-5) to (0.25-0.45) to (0-0.03) to (0-0.2); and preparing a light-emitting layer from water-permeable resin, long afterglow photoluminescence material, an anti-settling agent, light reflecting powder, a light diffusion agent, a diluent and a coupling agent, and the surface layer is coated with the light-emitting layer in a brushing or spraying manner. The light-emitting water-permeable paving material has a good sealing action to cement gel materials, and the problems that an ordinary cement paving material at present can easily fade and alkalify again, a landscape decoration effect at night is insufficient, and the like can be well solved.

Description

[0001] 【Technical field】 [0002] The invention belongs to the technical field of building materials, and specifically refers to a luminescent water-permeable pavement material and a preparation method thereof. [0003] 【Background technique】 [0004] With the continuous advancement of sponge city construction, the application of permeable paving materials is becoming more and more extensive. Cement permeable pavement materials are highly praised by owners, construction parties and citizens because of their wide source of raw materials, simple construction and good performance. The cement permeable pavement material is a composite cast-in-place product. Its base layer is plain concrete made of large particle size grading aggregate and cement, and the surface layer is made of small particle size grading aggregate, cement, toner, etc. Colored concrete. However, at present, the following shortcomings will appear in the application process of ordinary cement permeable pavement ma...
