二环戊二烯-苯酚树脂的合成及其在油性漆中的应用

SYNTHESIS OF DICYCLOPENTADIENE-PHENOL RESIN AND ITS APPLICATION IN OIL-BASED PAINT

在三氟化硼催化剂存在下，采用二环戊二烯和苯酚合成了二环戊二烯－苯酚树脂，并用此树脂和亚麻油配制成油性漆。列举了漆膜的各项性能指标。讨论了不同摩尔比二环戊二烯和苯酚，以及反应温度对树脂的软化点和游离酚含量的影响。试验表明，热塑性二环戊二烯－苯酚树脂可作为涂料用树脂，在一定程度上可改善漆膜的气干性。

At the presence of a catalyst BF 3, a dicyclopentadiene-phenol resin has been prepared, which is further formulated with linseed oil to form an oil-based paint The technical specification of the paint was listed This paper discussed the influence of various ratio between dicyclopentadiene and phenol, and reaction temperature on the softening point and free phenol level of the end resin It has shown that the thermoplastic dicyclopentadiene-phenol resin can be used as the binder of paint, improving the air dry property of the film to some extent
