Description
Technical field
The present invention relates to building material field, particularly to a kind of antibiosis mortar.
Background technology
Antibacterial and fungus are distributed widely on concrete structure, especially at warmed moist area concrete building
Basic part, on some hydraulic concrete buildings surfaces, in the xoncrete structure portion that percolating water often occurs
Position, the existence of antibacterial makes the local environment health level of these buildings be substantially reduced, and have impact on it and uses function
Performance.It is even possible that the most special building is lost uses function, such as medical building.Therefore, antibacterial
Mortar is for ensureing the Function of concrete structure and improving the life comfortableness all ten of building user
Divide necessity.
The antibacterial essence of copper is that copper can react with bacterial body internal respiration enzyme generation sulfhydryl, makes respiratory enzyme lose merit
Can, cause bacterial death.Therefore, nano cupric oxide is added to and mortar in mortar, can be made to produce antibacterial functions.
The shortcoming of this method is after in mortar, copper ion is constantly consumed, and causes its antibacterial effect to decline.If received
Rice CuO surface forms the tungsten oxide shell of porous, and tungsten oxide has special PhotoelectrochemicalProperties Properties, at photon
Under effect, copper ion can be reduced into cuprous ion, reach copper ion is carried out the purpose of slow release.For bag
The nano cupric oxide granule wrapping up in tungsten oxide mixes mortar, and its antibacterial effect mixes more than simple nano cupric oxide granule
The antibacterial effect of mortar, the release method of this outsourcing tungsten oxide has the biggest meaning for the persistency of antibiosis mortar
Justice.
Summary of the invention
For the deficiencies in the prior art, it is an object of the invention to provide a kind of antibiosis mortar.
Preparation technology of the present invention includes:
(1) mantoquita is dissolved
Lead to nitrogen deoxygenation in deionized water, after 30min, add copper sulfate and copper nitrate is stirred, stirring
Speed is 80～100r/min；
(2) dodecyl amine is added
Being stirred under room ambient conditions, mixing speed is 300r/min；
(3) ammonia is added
Ammonia is added after 10min；
(4) centrifugal mixer
Carrying out centrifugal mixer after 3h, mixing speed is 10000r/min, and mixing time is 5min；
(5) washing compound
Use deionized water wash 3 times, form component 1；
(6) vacuum drying component 1 levigate
(7) dispersed component 1
Component 1 powder is scattered in deionized water, adds isopropanol, stir 30min in 40 DEG C of constant temperature,
Form component 2；
(8) centrifugal mixer component 2
Phosphotungstic acid is added deionized water, ethanol and isopropanol, forms component 3, component 2 is added component 3,
Component 4 is formed after reaction 24h；
(9) centrifugal mixer component 4
Mixing speed is 10000r/min, and mixing time is 5min；
(10) scrubbed component 4
(11) vacuum drying component 4 levigate；
Baking temperature is 115～120 DEG C, it is thus achieved that component 5；
The present invention forms the tungsten oxide shell of porous by above-mentioned technique on cupric oxide nano grain surface, in preparation side
Improve to some extent than traditional method in method.On the one hand using dodecyl amine as protective agent, dodecyl amine is a kind of two
Parent's property organic compound, in the case of critical micelle concentration, in aqueous formed have hydrophobic cores and
The micellar aggregates of hydrophilic shell.On the other hand copper ion generates in ammonia hydrolyzed under basic conditions, co-precipitation
Cupric oxide nano grain wrapped up rapidly into micelle inner core in aqueous, both avoided further hydrolysis increase
Big particle size, turn avoid the clustering phenomena that the interaction between the nanoparticle of generation causes.
(12) component 5 is added cement to stir in advance
By component 5 and cement mixing, mixing speed is 20～30r/min, and mixing time is 1～2min., is formed
Component 6；
(13) sand and the total water consumption of 30% are added
Mixing speed is 30～50r/min, adds residue water after stirring 3～4min, improves rotating speed, stirring speed
Degree is 60～80r/min, and mixing time is 2～3min, it is thus achieved that the present invention.
Antibiosis mortar performance is not only relevant with each component material, and also relies on each component material to a great extent
The combining case of material.If stirring uneven, there is the most scattered material, the nanometer of outsourcing tungsten oxide in surface
Copper oxide does not obtains fully dispersed, and combined efficiency is low, and anti-microbial property is poor.The stirring means that the present invention provides passes through
Long-term practice obtains.Additionally, the made mortar of this stirring means is more closely knit, anti-microbial property is strong, mechanical property
Preferable.
Antibiosis mortar proportioning medium sand ratio of the present invention reduces 1.5～2% than traditional mortar, the material proportion of component 6
As follows:
Copper sulfate is the 2～2.5% of cement quality, and copper nitrate is the 1.5～1.8% of cement quality, and deionized water is
The 1.4～1.6% of cement quality, dodecyl amine is the 0.05% of cement quality, and ammonia is cement quality
0.3～0.4%, isopropanol is the 0.15% of cement quality, and ethanol is the 0.08% of cement quality, and phosphotungstic acid is water
The 0.5～0.6% of shale amount.
The made antibiosis mortar of the present invention has the advantage that antibacterial ability is strong, cost performance is good, before having preferably application
Scape.
