Embodiment 1

[0034] A high permeability permeable concrete cement, with a weight of mass, 15 parts of magnesium phosphate cement, 15 parts of polytegan siloxane, 25 parts of epoxy resin, 12 parts of phenolic resin, hydroxypropyl acrylate, propylene 3 parts of amide, 8 cellulose ethers, 3 parts of the active silica powder, 3 parts of the gelatin, 8 parts of polyvinyl alcohol, 6 pentaisaturate, 4 hydrated sulfide, calcium carbonate, 10 copies, twelve 3 parts of sodium alkylbenzene sulfonate, 1 part of 2,4-pentadiene salts, 3 cases of coupling agents, 4 defoamers, 45 water.

[0035] Among them, the zinc salt of 2,4-pentadiene is obtained by mixing 2,4-pentadienoic acid with a mass concentration of 12% a sodium hydroxide solution, so that pH = 8, add mass concentration. 10% of the zinc nitrate solution, stirred for 30 minutes, filtration, washing, drying, i.e., 2,4-pentadienic acid and zinc nitrate containing the molar ratio of 1: 1. Among them, it was washed twice with deionized water. The condit...

Embodiment 2

[0046] A high permeability permeable concrete cement, with a weight of 100 parts of magnesium phosphate cement, 20 parts of a polyorgan siloxane, 35 parts of epoxy resin, 15 parts of phenolic resin, 18 hydroxypropyl acrylate, propylene 6 parts of amide, 10 cellulose ethers, 8 parts of the active silica powder, 4 parts of the gelatin, 10 polyvinyl alcohol, 9 pentaisaturate, 7 hydrated sulfide, calcium carbonate, 12 copies, 12 2 parts of sodium alkylbenzenesulfonate, 2 parts of 2,4-pentadiene salts, 4 parts of coupling agent, 5 parts of defoam, 55 water.

[0047] Among them, the zinc salt of 2,4-pentadienate is obtained by mixing 2,4-pentadiene, a hydroxide solution having a mass concentration of 12%, so that pH = 10, add mass concentration. 10% of the zinc nitrate solution, stirred for 40 minutes, filtration, washing, drying, i.e., the molar ratio of zinc nitrate containing the zinc nitrate and the zinc nitrate solution of 1: 1.2. Among them, 3 times was washed with deionized water...

Embodiment 3

[0058] A high permeable permeable concrete cement, with a mass of 100 parts of magnesium phosphate, 15 parts of polytegan siloxane, 35 parts of epoxy resin, 12 parts of phenolic resin, hydroxypropyl acrylate, propylene 3 parts of amide, 10 cellulose ethers, 3 parts of the active silica powder, 3 parts of the gelatin, 10 parts of polyvinyl alcohol, 6 of the pentaerythyl alcohol, 7 hydrated sulfide, 20 copies of calcium carbonate, twelve 4 parts of sodium alkylbenzene sulfonate, 1 part of 2,4-pentadiene salts, 4 parts of the coupling agent, 4 parts of antifoam, 55 water.

[0059] Among them, the calcium carbonate crystal must perform organic modification, and the specific method is to immerse calcium carbonate in the polyethylene glycol 400, stand for 3 hours, filtered, then immerse into the polyglycerol ricin, ultrasonic oscillation 30 Minute, filtration, drying, The ratio of calcium carbonate should, polyethylene glycol 400, polyglycerol ricinate is 1: 8: 10.

Abstract

The invention provides a high-permeability permeable concrete cement. The main raw materials include magnesium phosphate cement, polyorganosiloxane, epoxy resin, phenolic resin, hydroxypropyl acrylate, acrylamide, cellulose ether, and active silica powder, bone cement powder, gelatin, polyvinyl alcohol, pentaerythritol, calcium sulfoaluminate hydrate, calcium carbonate whiskers, sodium dodecylbenzenesulfonate, zinc 2,4-pentadienoate, coupling agent, Defoamer and water, etc., have excellent bonding effect, meet the strength requirements of the road surface, and can meet the water permeability requirements of high-permeability permeable concrete.

Description

Technical field [0001] The present invention relates to the technical field of building materials, and in particular, to a high permeability permeable concrete cement. Background technique [0002] With the development of social economy and the process of urban construction, the landmark of modern cities is gradually covered by reinforced concrete house buildings and concrete-laid water-covered roads, and closed urban surfaces to the city compared to natural soils. problem. The traditional urban concrete pavement is blocked by mortar, and most of the formation of the surface extension flows into the river in the river, but also has increased the cost of municipal facilities, but also very easy to form flood disasters, urban groundwater can't get very good. Supplement, ground decline, urban temperature rises. [0003] With the process of China's sea urbanization, the water-based concrete pavement is widely used. Concrete, but also known as porous concrete, which is characterized b...
