A polyaspartic acid ester adhesive stone permeable pavement material

Abstract

The invention discloses a polyaspartic acid ester adhesive stone water permeable pavement material which consists of a component A, a component B and a component C, wherein the component A comprises castor oil polyhydric alcohols, solid polyaspartic acid ester, soft polyaspartic acid ester, a dispersant, a solvent-free defoaming agent, an active molecular sieve, active nano calcium carbonate, an inorganic pigment and a thixotropic agent; the component B is an HDI (Hexamethylene Diisocyanate) tripolymer solidifying agent; the component C is aggregate. The material has four beneficial effects, that is, firstly, the material is excellent in weather resistance and aging resistance; secondly, the material is high in strength, high in toughness and good in hydrophobicity, the anti-sliding property and the security of a pavement are improved, and the attractiveness of the pavement is also improved; thirdly, the material is excellent in water permeability and water permeability maintenance; fourthly, an original color of the aggregate can be maintained, and the aggregate can be of multiple colors to improve decoration performance.

Description

technical field [0001] The invention relates to the field of pavement materials, in particular to a polyaspartate adhesive stone permeable pavement material. Background technique [0002] Urban waterlogging has become an unavoidable and heavy topic every summer, and it is becoming more and more serious. The fragile urban drainage network is increasingly becoming the target of public criticism. However, the weak drainage capacity of sewers is only the direct cause of urban waterlogging. More and more urban waterlogging Impervious floors are also a significant cause of increased sewer drainage pressure. [0003] In October 2014, the Ministry of Housing and Urban-Rural Development issued the "Technical Guidelines for Sponge City Construction (Low-impact Development Rainwater System Construction)", which clarified the content of low-impact development stormwater system construction in the process of urban planning, engineering design, construction, maintenance and management , ...

AI Technical Summary

Problems solved by technology

However, the aging resistance of these permeable pavement materials is poor. After being put into use for 2-3 years, the aggregates on the surface are easy to fall off, and they can only be made of transparent colors at present, and cannot be used as colored cementitious materials.
