| 摘 要： | 以聚氨酯为成膜物质,将聚四氟乙烯(poly tetrafluoroethene,PTFE)和聚醚醚酮(polyether ether ketone,PEEK)分别加入涂料中制得具有疏水功能的复合涂料,分别研究不同质量分数的PTFE和PEEK对涂层疏水性能的影响;结果表明当2种物质的质量分数越高,水接触角越大,疏水性能越好;而相同条件下,PEEK涂层的疏水性能比PTFE涂层好。同时,研究紫外老化试验对PEEK涂层性能的影响,结果表明经700 h老化试验后涂层的疏水性能变化不明显,光泽保持率在94%以上。实践证明该涂层具有良好的疏水功能及长效性。

| Abstract: | Polyurethane is taken as film forming matter, and tetrafluoroethlene （PTFE） and polyether ether ketone （PEEK） are respectively added into paint to produce composite materials that are able to discharge. Impacts of PTFE and PEEK with different mass fractions on drainage performance of the coat are studied. The result indicates that when the mass fraction of the two substances is large, water contact angle is proportional to the hydrophobicity. However, under the same circum- stance, PEEK coat is superior to PTFE coat in hydrophobicity. In the mean time, impact of UV aging test on performance of PEEK coat is studied. The result shows that hydrophobicity of the coat changes indistinctively after 700 hours of aging test, gloss retention rate remains above 94%. It is practically proved that the coat is superior in hydrophobicity and durability. |
