The specific embodiment
As shown in Figure 1, a kind of seepage brick that contains the hydrophily epoxy adhesive is characterized in that: comprise seepage brick surface layer and seepage brick main body; On the described seepage brick main body fixedly the described seepage brick surface layer of seepage brick surface layer be provided with latticed groove; The cuboid that described seepage brick main body forms for the mixture compacting by hydrophily epoxy adhesive and cement mortar.
Described seepage brick surface layer and seepage brick main body adopt the vibration extrusion forming.
Described color burial depth is the 2-10 millimeter.
Described seepage brick body thickness is 2-8 centimetre.
Described hydrophily epoxy adhesive is comprised of bisphenol A type epoxy resin, curing compound, surfactant span and tween; Curing compound is one or more in aliphatic polyamine class curing compound, alicyclic polyamine class curing compound or the aromatic ring family polyamines class curing compound.
Described hydrophily epoxy adhesive is bisphenol A type epoxy resin E-44, E-42, E-35, E-31, E-20, E-14, E-12, E-06, one of E-03 or its any combination.
In the process of synthesis hydrophilic epoxy adhesive, for improving the activity of cementing agent, add this dish of surfactant in the synthesizing formula, can be S-20, S-40, S-60, S-80, one of S-85 or its any combination.
In the process of synthesis hydrophilic epoxy adhesive, for improving the activity of cementing agent, add the surfactant tween in the synthesizing formula, can be T-20, T-40, T-60, T-80, one of T-85 or its any combination.
Described hydrophily epoxy adhesive is under catalyst action, introduces the hydrophily functional groups such as hydroxyl, ehter bond by chemical reaction in the bisphenol A type epoxy resin strand.Namely under the effect of catalyzer, utilize the epoxy radicals of bisphenol A type epoxy resin with hydroxyl reaction in the surfactant, make epoxy resin one end contain hydrophilic radical, thereby have certain hydrophilicity.
Described catalyzer is etamon chloride, butyl triphenyl phosphonium bromide, benzyl triethyl ammonium bromide, a kind of or its any combination of benzyltriethylammoinium chloride and glyoxal ethyline.
Need add one or more in aliphatic polyamine, alicyclic polyamine class curing compound or the aromatic ring family polyamines class curing compound in the described epoxy adhesive.

The hydrophily epoxy adhesive of the present invention's preparation, the action principle in the modified cement process is:
At first, because the hydrophily epoxide resin polymer has hydrophily, and have polarity strong characteristics, minimizing along with moisture in the cement, hydrophily epoxy resin forms the film with higher adhesion stress, because the filling effect of film has improved the capillary structure of hardened cement paste, thereby stop up the hole in the mortar; Secondly, hydrated cementitious and polymer film forming carry out simultaneously, form at last be interweaved together inierpeneirating network structure of cement paste and polymer film, thereby have improved mechanical property and the durability of slurry.
Principle is in the water permeable paving material product:
At first, owing to the hydrophily of hydrophilic compounds and with active group, behind the resin solidification, formation is take the hydrophilic compounds decentralized photo as " island ", connecting phase epoxy resin is " island structure " in " sea ", reaches toughness reinforcing purpose, shows as water-permeable brick compressive strength and increases substantially; Secondly, because the microphase-separated of resin after solidifying, hydrophilic radical tends to be distributed in the external surface of resin molding, and ehter bond or the hydroxyl of this epoxy resin molecular side chain outwards stretch, so that the external surface of resin coating water-permeable brick has water-wet behavior.Because in the permeable products solidifying forming process, the aggregate such as stone, quartz sand presses together, but because aggregate has particle diameter, and exists certain sphericity, form the tiny tubular conduit that mutually connects between the aggregate, when water contacts with this passage, because the water-wet behavior of this resin, water infiltrates rapidly tube wall, and liquid level is spill in the pipe, the additonal pressure that the curved liquid surface that forms produces is pointed to tubule, promotes passing through of water.
