为了开发出适用性好、性价比高的建筑铝型材用FEVE(氟烯烃-乙烯基醚共聚物)型氟碳粉末涂料,重点分析了不同厂家的氟树脂、不同种类异氰酸酯及颜填料的含量对FEVE型氟碳涂层性能的影响。对比了不同类型耐候性粉末涂料的耐老化性,认为丙烯酸树脂和超耐候羟基树脂比较适合改性氟树脂;进一步对比了这2类树脂改性氟树脂后涂层的性能。结果表明:选用丙烯酸树脂改性氟树脂与自封闭异氰酸酯BF-1540制备FEVE氟碳粉末涂料,颜填料用量为22.5%时所得涂层性能优异,性价比高。 相似文献

The growth of the powder coating business is affected by the toxicological effects of the raw materials used in the coating formulation and the saturation of the present market for powder coatings, being limited to general metal applications only. This has a strong influence on the long-term research programmes at both raw materials suppliers and powder paint producers. In the last decade of the 20th century, we witness appearance of several new types of toxicologically-safe powder coating systems on the commercial scale. At the same time, there is strong evidence of efforts to penetrate new market fields where powder coatings are not typically used. This includes the markets for automotive clear top coatings, can and coil coatings, coatings for industrial wood, plastics and paper. The new developments in the chemistry of powder coatings are followed by changes and improvements in the production technology for powder coatings as well as developments of new application techniques. This paper summarises the research work on chemistry, production and application technology of powder coatings and tries to extrapolate the tendencies in the years to come in order to predict the achievements and the impacts on the paint industry. 相似文献

滑石粉对环氧改性有机硅耐高温涂层性能的影响 总被引:1,自引:0,他引:1
以滑石粉和玻璃粉为主要填料,以环氧改性有机硅树脂为基料,制备了环氧有机硅耐高温涂层,研究了涂层附着力、冲击强度及耐急热性能,讨论了滑石粉质量分数对涂料性能的影响及影响机理。结果表明:随着滑石粉质量分数的增加,涂层的耐高温性能和力学性能都是先增强后减弱,以35%为最佳;涂层能够经受600、700和800℃的急热冲击;室温冲击强度为5 J;600℃高温处理后附着力由室温的9 MPa增大至32.8 MPa。当滑石粉质量分数过低,玻璃粉质量分数过高时,涂层在高温下发泡膨胀不稳定;当滑石粉质量分数过高,玻璃粉质量分数过低时,涂层在高温下没有足够的玻璃相,不能形成具有一定粘结强度的涂层。 相似文献

Radiation-curable powder coatings are now in the early stages of commercialization. For years, the coatings industry has sought
ways to lower the curing temperature of powder coatings. UV-curable powder coatings offer the possibility of curing powder
coatings at temperatures as low as 120°C. Radiation-curable powder coatings also offer high cure speed and relatively low
energy consumption. As each application requires its own coating performance, two different maleate-vinyl ether-based binders
for UV-curable powder coatings have been developed. With these binders the balance between flexibility and hardness of the
coating can be adjusted with proper formulation. In this paper, the curing characteristics and coating performance of several
UV-powder coating formulations are described. In addition, a comparison between conventional powder coatings and UV-powder
coatings is provided.
