Abstract

The invention belongs to the technical field of epoxy resin preparation and discloses an epoxy resin seepy material and a preparation method thereof and application. The epoxy resin seepy material is prepared from, by weight percentage, 5-35% of epoxy resin, 5-30% of modified self-emulsifying epoxy hardener, 0.5-3% of polyether polyamine, 0.5-3.5% of epoxy resin accelerator, 1-3.5% of epoxy resin diluent, 35-10% of water and 53-15% of inorganic filler. The modified self-emulsifying epoxy hardener is ricinoleic acid and / or fatty polyamine and / or alicyclic polyamine modified by a polymer of the ricinoleic acid. The epoxy resin seepy material has excellent seepy and breathable performances, the pore diameter of the epoxy resin seepy material is smaller than 20 [mu]m, the porosity is larger than 20%, the water absorption rate is larger than 20%, the pore diameter distribution is uniform, the surface is bright and clean, and the epoxy resin seepy material can be used for manufacturing ceramic industry slip casting dies, filter materials and air purification materials.

Description

technical field [0001] The invention belongs to the technical field of epoxy resin preparation, and in particular relates to an epoxy resin water-permeable material and its preparation method and application. Background technique [0002] Water-permeable material is a kind of porous material, which realizes the transfer of water and gas inside the material through the pore channels inside the material. It is widely used in construction, environmental protection, chemical industry, water treatment, catalysis and other fields. For example, urban roads use permeable materials for drainage, catalyst carriers, filter materials in the water treatment process, filter materials used in the separation process of chemical production, and mold materials for grouting molding used in the ceramic industry. [0003] At present, there are many preparation processes and methods for water-permeable materials. Most of the epoxy resin microporous water-permeable materials prepared with epoxy re...
