Embodiment 1

[0034] A high-permeability permeable concrete binder, in parts by weight, comprising: 100 parts of magnesium phosphate cement, 15 parts of polyorganosiloxane, 25 parts of epoxy resin, 12 parts of phenolic resin, 13 parts of hydroxypropyl acrylate, propylene 3 parts of amide, 8 parts of cellulose ether, 6 parts of activated silica powder, 3 parts of gelatin, 8 parts of polyvinyl alcohol, 6 parts of pentaerythritol, 4 parts of calcium sulfoaluminate hydrate, 10 parts of calcium carbonate whiskers, twelve 3 parts of sodium alkylbenzene sulfonate, 1 part of zinc salt of 2,4-pentadienoate, 3 parts of coupling agent, 4 parts of defoaming agent, 45 parts of water.

[0035] Wherein, 2,4-pentadienoic acid zinc salt is prepared by the following method: 2,4-pentadienoic acid is uniformly mixed with a sodium hydroxide solution with a mass concentration of 12%, so that the pH=8, and the mass concentration is added 10% zinc nitrate solution, stirred and reacted for 30 minutes, filtered, was...

Embodiment 2

[0046] A high-permeability permeable concrete binder, in parts by weight, comprising: 100 parts of magnesium phosphate cement, 20 parts of polyorganosiloxane, 35 parts of epoxy resin, 15 parts of phenolic resin, 18 parts of hydroxypropyl acrylate, propylene Amide 6 parts, cellulose ether 10 parts, activated silica powder 8 parts, gelatin 4 parts, polyvinyl alcohol 10 parts, pentaerythritol 9 parts, calcium sulfoaluminate hydrate 7 parts, calcium carbonate whiskers 12 parts, twelve 4 parts of sodium alkylbenzene sulfonate, 2 parts of zinc salt of 2,4-pentadienoate, 4 parts of coupling agent, 5 parts of defoamer, 55 parts of water.

[0047] Among them, the 2,4-pentadienoic acid zinc salt is prepared by the following method: 2,4-pentadienoic acid is uniformly mixed with a sodium hydroxide solution with a mass concentration of 12%, so that the pH=10, and the mass concentration is added 10% zinc nitrate solution, stirred and reacted for 40 minutes, filtered, washed and dried to obt...

Embodiment 3

[0058] A high-permeability permeable concrete binder, in parts by weight, comprising: 100 parts of magnesium phosphate cement, 15 parts of polyorganosiloxane, 35 parts of epoxy resin, 12 parts of phenolic resin, 18 parts of hydroxypropyl acrylate, propylene 3 parts of amide, 10 parts of cellulose ether, 6 parts of activated silica powder, 3 parts of gelatin, 10 parts of polyvinyl alcohol, 6 parts of pentaerythritol, 7 parts of calcium sulfoaluminate hydrate, 10 parts of calcium carbonate whiskers, twelve 4 parts of sodium alkylbenzene sulfonate, 1 part of zinc salt of 2,4-pentadienoate, 4 parts of coupling agent, 4 parts of defoaming agent, and 55 parts of water.

[0059] Wherein, the calcium carbonate whiskers are organically modified, and the specific method is: immerse the calcium carbonate whiskers in polyethylene glycol 400, let stand for 3 hours, filter, then immerse in polyglycerol ricinoleate, and ultrasonically vibrate for 30 Minutes, filtered, dried, that is. The ma...

Abstract

The invention provides a high-permeability permeable concrete cement agent mainly comprises magnesium phosphate cement, polysiloxane, epoxy resin, phenolic resin, hydroxypropyl acrylic acid ester, acrylamide, cellulose ether, active silica powder, bone glue powder, gelatin, polyvinyl alcohol, pentaerythrite, calcium sulphoaluminate hydrate, calcium carbonate whiskers, sodium dodecyl benzene sulfonate, 2,4-zinc pentadienate salt, a coupling agent, a defoaming agent, water and the like. The high-permeability permeable concrete cement agent has excellent bonding effect, requirements of pavement strength can be met, and the permeable requirement of high permeability permeable concrete can be met.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a high-permeability permeable concrete binder. Background technique [0002] With the development of social economy and the process of urban construction, the landmarks of modern cities are gradually covered by reinforced concrete buildings and impermeable concrete paved roads. Compared with natural soil, the closed urban surface brings a series of problems to the city. question. The traditional urban concrete pavement blocks the water vapor exchange due to the condensation of the mortar, and most of the surface runoff flows into the river through the drainage channel, which not only increases the cost of municipal facilities, but also easily causes flood disasters, and the urban groundwater cannot be well recovered. Supplement, the ground drops and the temperature of the city rises. [0003] With the development of sea surface urbanization in China, permeable concre...
