Abstract

The invention relates to the technical field of pavement materials, in particular to a natural colored water-permeable adhesive stone pavement material and a preparation process thereof. The natural colored water-permeable adhesive stone pavement material is prepared by mixing 80-90 parts of natural colored stone aggregate, 15-25 parts of cellulose, 3-8 parts of a cementing material and 5-10 parts of attapulgite filler, wherein the cellulose wraps the surface of the natural colored stone, the cementing material is prepared from 2-7 parts of modified polyol and 1-3 parts of an HDI curing agent, and the modified polyol is obtained by grafting 3, 3 '-dichlorodiphenyl disulfide to polyether polyol. According to the invention, disulfide bonds are introduced into the adhesive material, so that the self-repairing capability of the material is improved, rainwater is prevented from invading into the material to cause a corrosion phenomenon, abundant hydroxyl groups on cellulose and hydroxyl groups on the surface of the adhesive material generate hydrogen bond self-assembly, and the falling between the cementing material and aggregate is prevented.

Description

technical field [0001] The invention relates to the technical field of pavement materials, in particular to a natural color permeable adhesive stone pavement material and a preparation process thereof. Background technique [0002] Traditional pavement is a sealed structure to prevent moisture from infiltrating and causing damage to it. However, with urban development and industrial activities, the area of ​​closed pavement increases rapidly, resulting in the inability of rainwater to penetrate into the ground, forming pavement water, and causing ecological imbalance. In order to restore the natural hydrological cycle and reduce the risk of urban flooding, a permeable pavement is used. When a rainfall event occurs, water can quickly penetrate into the ground through the pavement structure, completing urban drainage and supplementing the natural water cycle. [0003] In order to achieve high permeability, a pavement structure rich in voids is currently the most feasible and e...
