Resin coating with crosslinking agent
2017-3-30 10:51:43
Resin coating with crosslinking agent,All kinds of resin coating each have advantages and disadvantages, facing the different natural environment, used alone can achieve a coating performance is always limited.
So according to the characteristics of the natural environment and coating performance requirements, a targeted select best matrix resin or synthetic varieties (or combination). Of crosslinking agent and fillers, such as formulation. System of form a complete set of coating and coating process, in order to achieve more excellent protection effect.
Overall, excellent weatherability. Sand rain erosion resistance. Hot and humid, salt fog resistance and ice prevention performance. Such as convenient construction and green environmental protection will be the future development direction of wind power blade coating.
The existing chemical compound with fluorine resin and other resin. Foster strengths and circumvent weaknesses, is a practical. The development direction of theoretical research significance; In addition, starting from the molecular design and synthesis of new type structure of fluorine resin or to fluorinated polyurethane resin, such as modified, in order to obtain excellent comprehensive performance of the matrix resin, it is worth to carry out the research topic.
Yang studied in PTFE, such as sand blasting of PTFE. The two kinds of PTFE. RTV fluorosilicone coating and fluorinated polyurethane is a kind of thin thin ice on the surface of the water meter performance. Smooth surface of the fluorine polymer can obviously reduce the adhesion of ice on the coating surface, but not significantly reduce the accumulation of ice on the surface.
Sandblasting the surface of PTFE with micro rough structure and super hydrophobic properties, can effectively reduce the accumulation of ice. However, under the condition of low temperature and humidity environment, due to the moisture condensation in the surface micro protuberant clearance, the hydrophobic performance is significantly reduced, eventually led to once the ice formed in the slightly rough surface, the ice adhesion increase instead.
Peng, etc on the wind vane a super hydrophobic PVDF coating was prepared, its water contact Angle and sliding Angle can reach 156 ° and 2 ° respectively, compared with no PVDF coating protection of the surface of the blade, with very good freezing resistance.
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).
Li Rujian, hydroxy fluorocarbon resin and solid thermoplastic acrylic resin was prepared by a wind vane with paint, after artificial accelerated aging 6000 h of light rate is about 80%.
In addition, the coating has excellent wear resistance. Hydrophobic and self-cleaning, etc. 'and so on will be fluoride - alkyl vinyl ether copolymer alternately wind-power blades as one of the matrix resin used for coating preparation, good weatherability and fouling resistance of protective coating.
XiaoMing, hydroxyl acrylic emulsion. Waterborne fluorocarbon emulsion reaction with water dispersible isocyanate was a wind-power blades with waterborne fluorocarbon paint, weather resistance of up to 3000 h, more than 10 mpa, adhesion resistance to more than 2000 h salt spray test, abrasion resistance (1000 g, 1000 r/min) < 60 mg.
Zhang Lexian adopts excellent weatherability of fluorocarbon resin. Organic silicone modified acrylic resin and elastic linear polyester resin compound with resin as matrix, using uv absorption effect and light catalytic oxidation effect of nano titanium dioxide and fillers and additives of proper preparation of wind-power blades got a high-performance protective coatings.
Through the formulation and process optimization, get coatings with good adhesion. High strength and toughness, excellent wear resistance. The high-speed particle impact resistance. Resistance to uv and salt fog resistance, also have a certain stain. Anti-icing and self-cleaning.
Ying-qiang zhang, etc. In the first place by trimethylolpropane IPDI and five get a fluoride fluorine propyl alcohol to synthesize diisocyanate, and then with polyether glycol. Polycarbonate glycol aqueous synthesis by fluorinated polyurethane resin coating. The coating hardness can be up to 3 h, water contact Angle of 106 °.
