Abstract

The invention discloses an epoxy water-permeable brick and belongs to the technical field of building materials. The water-permeable brick comprises a bottom layer and a surface layer; the surface layer comprises the following raw materials in parts by weight: 88-96 parts of silica sand, 1.95-6.86 parts of epoxy resin, 0.39-2.05 parts of a curing agent, 0.5-5.4 parts of a hydrophilic curing agent,0.05-3.00 parts of a coupling agent, 0.05-3.00 parts of water and 0.1-0.5 part of nano silica. According to the invention, the hydrophilic curing agent and the non-hydrophilic resin are used so thata water permeation function is realized. Compared with the prior art, the water-permeable brick has the advantages that the raw materials are easy to obtain, the process is simple, the preparation cost is low, the prepared water-permeable brick is ecological and environmentally friendly, and the water-permeable, wear-resistant and water-retaining properties are good.

Description

technical field [0001] The invention relates to a permeable brick, in particular to an epoxy permeable brick, which belongs to the technical field of building materials. Background technique [0002] Permeable bricks originated in the Netherlands. During the process of building the city from the sea, the Dutch found that the ground after the sea water was drained would cause continuous land subsidence due to long-term lack of contact with water. Once the dykes on the coastline are washed away, the seawater will quickly rush to cities much lower than sea level and submerge the entire coastal city. In order to prevent the ground from sinking, the Dutch made a small pavement brick with a length of 200 mm, a width of 100 mm, and a height of 50 or 60 mm, which was laid on the street surface, and a gap of 2 mm was reserved between the bricks. In this way, when it rains, the rainwater will seep into the ground through the gaps between the bricks. Afterwards, the Shubroko Company ...
