Abstract

The invention discloses an impact-resistant polymer water-permeable material and belongs to the technical field of ecological materials. According to the method disclosed by the invention, the molecular rheological property and the impact resistance are improved by improvement of movement of polylactic acid molecule chain segments by virtue of high-steric hindrance blocking, under the high-temperature action, vermiculite is expanded, polylactic acid and hexacyclic stone components are filled, certain purification treatment is carried out on permeated water, when the impact-resistant polymer water-permeable material is used for treating acidic water and rain water, a high-hydrogen-ion concentration can excite the hexacyclic stone to generate negative ions for neutralization, and acidification corrosion to the water-permeable material is avoided. The pH of the permeated water is smaller than the isoelectric points of gelatin and mussel mucoprotein, so that the gelatin and the mussel mucoprotein are positively charged and are mutually exclusive with the hexacyclic stone, the hydrophobic permeability is improved, chitosan is subjected to acid dissolving, a large number of water-repellent groups are introduced, the hydrophobic property is improved, the retention time of the water-permeable material in the water-permeable process can be controlled in an auxiliary mode, and the water-permeable effect is improved. According to the invention, the problems that an existing common water-permeable material is poor in impact resistance and treatment effect on acidic water and acid corrosion can occur are solved.

Description

technical field [0001] The invention belongs to the technical field of ecological materials, and in particular relates to an impact-resistant polymer water-permeable material. Background technique [0002] At present, the places where urban residents live are mainly surrounded by urban squares, commercial streets, sidewalks, community activity places, parking lots, etc., which are paved with impermeable materials such as granite, marble, glazed tiles, cement and asphalt. The urban environment is very dangerous. When it rains, the hardened ground completely prevents the rainwater from penetrating directly into the ground, and the accumulated water on the ground makes people's travel very inconvenient; the precious water resources finally flow away with the drainage pipes, which increases the burden on the urban drainage facilities; the rainwater The large loss of rainwater makes it difficult for the groundwater level to rise, which directly affects the health of urban vegeta...
