Fluosilicate paint crosslinking agent
Fluosilicide coating crosslinking agent crosslinking a lot of material can make sodium glass cross linking, these substances are called crosslinking agent or hardener.
In the 1940s, sodium fluorosilicate was widely used as crosslinking agent. The hydrolysis of the water glass is in the direction of the formation of silicic acid. The modified coating has good water resistance.
The reaction can be expressed as: 2 (Na2O? NSiO2) + Na2SiF6 + mH2O6NaF + (2n + 1) SiO2? mH2O
A hydrophobic copolymer was also prepared. TiO2 is used in ptfe film, which has super hydrophobic and self-cleaning properties. The surface modification of metal oxide (ZrO2) with different fluorinated alkyl silicon is used to make the surface more hydrophobic. On the ZrO2 membrane of hydrophilic properties, the membrane has good hydrophobic properties by grafting of fluorinated alkyl silicate (1H, 1H, 2H, 2H 1 perfluorodecyl triethoxysilicon). The hydrofluorinated polysiloxane is prepared by using protons or lewis acids as catalysts, and the coating allows water droplets to slip naturally at 30 degrees on the surface.
The key to meet the ice - proofing requirement is functional facial filler. The absorption of thermal radiation coating has made progress in the study of the effect of the absorption of heat, such as adding graphite to blackboard paint, adding asphalt to phenolic black, etc. With C, Al and organic carbon black, SiO2 was used as emitter to improve the spectral selectivity, but the heat transfer effect was not good.
It is made of iron and black water glass, the absorption rate is improved, but it is not waterproof. Liu shengfeng et al. used silicone or acrylic acid modified silicone resin to mix FeMnCuOx into a transmitter, which was selectively enhanced, but expensive. Using silicon modified acrylic acid mixed with Fe2O3 - Cr2O3 and MnO2 as pigments, the absorption emission was relatively high, but easy to age and deformation.
In the case of linsmanlike crystal PbS mixed with ethylene-propylene rubber or fluorine resin, it is easy to oxidize and lose the transformation and other defects. The selective absorption coating prepared by the powder flame spraying method was adopted by wu GUI and other people. The spectrum was selective and good, but it was easy to cause pollution to the environment.
Huxiahua of chongqing university was modified with silica sol by fluorosilicate, and then mixed with styrene-acrylic emulsion, and reactive synthetic transition metal composite oxide FeMnCuOx, which was made into an anti-icing coating. The coating has good anti-icing properties and has the effect of reducing the icing on the surface of the substrate, and has good binding force and weatherability.

The size of the paint has a great influence on the performance of the paint. Normally, when the thickness of the coating increases, the absorption rate increases, until it tends to a stable value. Therefore, it is important to keep the low emission rate and high absorption rate at the same time. The thickness of the heat-absorbent coating can not be too thick, and the paint particle size should be small, and the suitable average particle size is usually about l0um.
Barthlott plant by observing the microstructure on the surface of the blade, the main characteristic is found on the surface of the ultra thin water meter with nanoscale rough structure and surface wax, which provide a certain amount of hydrophobic. The process of preparation of superhydrophobic coating is as follows: first, prepare the hydrophobic materials with low surface energy; In this paper, the dual coarse structure of nanometer nanometer is constructed, which provides a certain superhydrophobic effect.
Ogawa et al. used the method of radiofrequency plasma etching to treat the surface of the glass to a certain degree of roughness, and then the surface treatment was treated with chlorosilane, and the transparent superhydrophobic glass was obtained.
Hozumi et al. studied the preparation of superhydrophobic transparent coatings with chemical vapor deposition (CVD) technology. By controlling the gas pressure and substrate temperature, make deposited film surface to obtain a certain roughness, containing perfluorinated alkyl silane as gas source, through the deposited film in the surface of substrate, super hydrophobic membrane made of transparent.
Tadanaga et al. used sol-gel technology to prepare the transparent aluminum oxide film with boehm structure, immersed in boiling water, and by changing the processing time, the surface of the coating could obtain the roughness of 20 ~ 50nm. Finally, the surface of the coating is treated with perfluoroalkyl silane, which can be transparent and hydrophobic.
The hydrophobic coatings can also be prepared by means of polymethyl methacrylate (PMMA) and polyethylene terephthalate (PET).
