Low surface energy polymer paint crosslinking agent
Low surface energy can easily be found in the polymer surface, improve the water resistance of the polymer, and make the polymer better hydrophobic and self-cleaning. Therefore, the organic silicon, organic fluorine and other substances which have the obvious advantages of oxidation and low surface can be used to prepare superwater self-cleaning surfaces.
Silicone resin is widely used in various fields such as high-voltage outdoor insulation, anti-fouling paint and ultra-hydrophobic materials. Polydimethylsiloxane (PDMS) is commonly used to prepare hydrophobic surfaces due to its inherent deformability and hydrophobic properties.
Crosslinking agent is a kind of material that can bridge the lining of the linear molecules, allowing multiple linear molecules to bond to each other. A substance that promotes or regulates the formation of a covalent bond or ionic bond between the polymer chains.
Documentsmust agent means as a monomer in the polymerization into the molecular chain structure of National People's Congress, or as a component added to the adhesive, can stable storage, only when heated to a certain temperature or radiation condition that crosslinking reaction to happen. Agent on common stated alkene monomers, such as hydroxyl ethyl acrylate, acrylic acid, hydroxypropyl acrylate, methyl acrylic acid and hydroxy ethyl methacrylate, methyl hydroxypropyl acrylate, divinyl benzene and N - methylol acrylamide, diacetone acrylamide.
Jin was prepared by using the method of laser etching in PDMS surface with micron, nano rough structure super hydrophobic surface, measured on the surface of the water contact Angle of 160 °, rolling Angle less than 5 °, with good hydrophobic self-cleaning performance.
Khorasani using pulse CO2 laser as excitation source in PDMS surface such as the introduction of peroxide groups on the surface modification, using peroxide groups in PDMS surface grafting of the 2 - hydroxyethyl methacrylate polymer.
Experiments show that, as a result of PDMS surface porous and the existence of polymer chain segment, high coating on the surface of the water contact Angle of 175 °, has excellent hydrophobic performance.
Chinese name: Diethyl toluene diamine(DETDA)
Diethyltoluenediamine packingļ¼ net weight 200KG/ galvanized iron drum (a small cabinet pallet loaded 16 tons), 1000KG/IB barrels (a small cabinet loaded 18 tons or 23 tons of ISOTANK).
Silicon-fluorinated polymethyl methacrylate with certain transparency is also widely used in the preparation of hydrophobic self-cleaning coatings. Hai-yang wei, micro emulsion polymerization of methyl methacrylate and acrylic acid prepared by the perfluorinated alkyl ethyl ester of random copolymer super hydrophobic coating, the hydrophobic surface by the low surface energy material and suitable for rough structure, the contact Angle of coating film is higher than 150 ° and rolling Angle less than 3 °, has a good super hydrophobic self-cleaning performance.
Hwang, by adopting the method of spray deposited by 3 - [3] [(trimethyl silane) oxygen - silicon] propyl acrylate (SiMA) and methyl methacrylate (MMA) the random copolymer of transparent super hydrophobic surface was prepared. Micro rough structure of the surface is similar to a lotus leaf surface, high water contact Angle and low lag Angle, in addition the hydrophobic surface is transparent in the visible wavelength range.
At present, the preparation of spray deposition as a simple super hydrophobic on the surface of the water meter method is suitable for large-scale preparation process, and is expected to become a more economic preparation method in industrial application.
Its ehrs with CF4 plasma etching method and hydrolysis process has the PMMA transparent super hydrophobic surface. Surface formed by plasma etching in PMMA nano-sized cylinder with high length-diameter ratio, but because of some unnecessary layer accumulation resulting in a decline in its transparency, so the subsequent hydrolysis process can remove the surface deposition of metal fluorides, increase its transparency, the water contact Angle of the hydrophobic coating is about 160 °.
Plasma etching the surface modification and the hydrolysis process is a common and environmentally friendly processing methods, to improve the ability to clean and maintain its high transparency at the same time to expand the application fields of PMMA, such as can be applied to intelligent window, solar panels and biomedical devices, etc.
Usually low surface energy material is the first choice for the preparation of hydrophobic self-cleaning surface material, but studies have shown that organic material with porous structure alkane (such as polyethylene, polystyrene, etc.) can also be used for the preparation of hydrophobic surface.
