Description
Technical field
The present invention relates to a kind of preparation methods of super-hydrophobic photo-thermal suppression ice coating.
Background technique
With the deterioration of global climate and the destruction of environment, the natural phenomena of icing certain fields of human society gradually
Develop into a problem, the formation of ice and snow often produces transportation, transmission line of electricity, aircraft, building and communal facility etc.
Raw tremendous influence.Therefore, new deicing, anti-icing system are researched and developed, avoid ice disaster caused by human society
Harm is of great significance.Wherein, the material for being related to pressing down ice is broadly divided into active deicing and passive deicing material, and every kind of material
Expect single effect, can not reach simultaneously prevent freeze and freeze after can efficiently deicing technical effect.
Summary of the invention
The invention solves existing suppression ice material result is single, can not reach simultaneously prevents from freezing and can efficiently remove after freezing
The problem of ice, and a kind of system for pressing down ice coating using iron copper manganese Metal salt and nano silica as the super-hydrophobic photo-thermal of raw material is provided
Preparation Method.
A kind of preparation method pressing down ice coating using iron copper manganese Metal salt and nano silica as the super-hydrophobic photo-thermal of raw material,
It is to sequentially include the following steps:
One, solar energy optical-thermal powder is prepared:
Nine water ferric nitrates, nitrate trihydrate copper, tetrahydrate manganese chloride and water are mixed, mixed solution is obtained, then by quality hundred
The sodium hydroxide solution that score is 3%~8% is instilled in container simultaneously and is stirred with mixed solution, obtains mixture, and be added dropwise
It is 10.5~11.5 that process control rate of addition, which keeps mixture pH, then mixture is stood 1h~4h at room temperature, discarded
Supernatant simultaneously filters, and is precipitated, and under conditions of temperature is 50 DEG C~120 DEG C, will precipitate dry 1h~3h, then grinds,
Finally with heating rate for 5 DEG C/min~20 DEG C/min, temperature is warming up to 600 DEG C~800 DEG C, and temperature be 600 DEG C~
Under 800 DEG C and air atmosphere, 1h~2h is calcined, solar energy optical-thermal powder is obtained；
The quality of the nine water ferric nitrates and the volume ratio of water are 1g:(10~20) mL；In the nine water ferric nitrates
Iron ion and nitrate trihydrate copper in copper ion molar ratio be 1:(0.9~2)；Iron ion in the nine water ferric nitrates
Molar ratio with the manganese ion in tetrahydrate manganese chloride is 1:(0.9~2)；The hydroxide that the mass percent is 3%~8%
Hydroxyl molal quantity in sodium solution is identical as the anion mol number in mixed solution；
Two, nanoparticles solution is prepared:
By gas phase SiO2Nano particle is added in hexamethylene, obtains gas phase SiO2Nanoparticles solution, by gas phase SiO2It receives
Rice grain solution ultrasonic disperse 5min~30min, obtains uniform SiO2Suspension, under room temperature and stirring condition, by 16
Alkyl trimethoxysilane and glacial acetic acid are added dropwise to uniform SiO2In suspension, stirs 1 day~2 days, obtain nanometer
Grain solution；
The gas phase SiO2The concentration of nanoparticles solution is 5mg/mL~25mg/mL；The gas phase SiO2Nanometer
The mass ratio of grain and hexadecyl trimethoxy silane is 1:(2~4)；The gas phase SiO2The matter of nano particle and glacial acetic acid
Amount is than being 1:(0.5~1)；
Three, solar heat matrix is prepared:
The curing agent of solar energy optical-thermal powder, dimethyl silicone polymer and dimethyl silicone polymer is mixed, then in ball
1h~3h is ground in grinding machine, obtains coating, and under conditions of being 100 μm~600 μm with coating thickness, coating is coated in substrate
On, obtain solar heat matrix；
The mass ratio of the solar energy optical-thermal powder and dimethyl silicone polymer is 1:(5~15)；
Four, it sprays:
1., using nanoparticles solution as spray coating liquor, spray gun air pressure be 0.4MPa~0.7MPa and distance be 15cm~
Under conditions of 20cm, 15 layers~50 layers nanoparticle coating are sprayed in solar heat substrate upper surface, are then 100 DEG C in temperature
Under conditions of~135 DEG C, 10min~20min is heated, obtains the matrix after spraying for the first time；
2., using nanoparticles solution as spray coating liquor, spray gun air pressure be 0.4MPa~0.7MPa and distance be 15cm~
Under conditions of 20cm, the substrate upper surface after first time sprays continues to spray 15 layers~50 layers nanoparticle coating, then exists
Under conditions of temperature is 100 DEG C~135 DEG C, 20min~30min, the matrix after obtaining second of spraying are heated；
3., using nanoparticles solution as spray coating liquor, spray gun air pressure be 0.4MPa~0.7MPa and distance be 15cm~
Under conditions of 20cm, the substrate upper surface after spraying at second continues to spray 15 layers~50 layers nanoparticle coating, then exists
Under conditions of temperature is 100 DEG C~135 DEG C, 30min~50min is heated, obtains the matrix after third time sprays；
4., using nanoparticles solution as spray coating liquor, spray gun air pressure be 0.4MPa~0.7MPa and distance be 15cm~
Under conditions of 20cm, the substrate upper surface after third time sprays continues to spray 15 layers~50 layers nanoparticle coating, then exists
