Abstract

The invention discloses a resin and a sand-based pervious material. The resin is prepared from the following raw materials in parts by weight: 68 to 85 parts of epoxy resin, 15 to 27 parts of modifying agent, 0.05 to 0.2 part of light stabilizer, 0.03 to 0.15 part of antioxygen, 0.2 to 1 part of dispersing agent, 10 to 20 parts of micropore generating agent, and 0.01 to 0.06 part of catalyst. A preferable preparation method of the resin comprises the steps of adding the epoxy resin, the modifying agent and the catalyst into a reaction still, polymerizing at the temperature of 70 to 85 DEG C for 6 to7 hours, then cooling to the room temperature, and adding the dispersing agent, the light stabilizer, the antioxygen and the micropore generating agent for stirring uniformly. The sand-based pervious material is prepared from sands and the resin. The invention solves the problems that a sand-based pervious brick prepared by utilizing an existing resin has low pervious efficiency, poor continuous pervious performance, and non-ideal weather fastness.

Description

technical field [0001] The invention relates to the technical field of new materials, in particular to a resin and sand-based water-permeable material. Background technique [0002] Sponge city is a new generation of urban stormwater management concept. It refers to the city's good "elasticity" in adapting to environmental changes and responding to natural disasters caused by rainwater. It can also be called "water elastic city". The international general term is "low-impact development stormwater system construction". When it rains, it absorbs, stores, infiltrates, and purifies water, and "releases" the stored water for use when needed. [0003] Under the new situation and new requirements of strengthening the construction of new-type urbanization and sponge city construction, based on the urgent needs of the market, highlighting the key points, combining the development status of various parts of our country, and referring to foreign advanced development experience, we ha...
