    • An air-cross-linkable lacquer binder comprising a copolymer of copolymerized units of from 10 to 40% by weight of glycidyl acrylate, glycidyl methacrylate or a mixture thereof, and 70 to 10% by weight of at least one other vinyl monomer which has been reacted with (based in each case on the quantity of lacquer binder) of from 0.01 to 30% by weight of at least one wood preservative having at least one glycidyl-reactive hydrogen atom and from 20 to 60% by weight of at least one air-drying natural or isomerized fatty acid and from 0 to 10% by weight of a dicarboxylic acid anhydride, said lacquer binder having an average molecular weight M.sub.n of from 1500 to 15,000 and an acid number of from 3 to 15. One special advantage of the lacquer binder according to the invention is that the wood preservatives are chemically fixed to the polymer molecule so that their release is retarded and the protective action is prolonged. Another advantage is the possibility to prepare well-drying wood preservative systems with lacquers which have not been treated with drying agents.
    • 一种可空气交联的漆粘合剂,其包含共聚单元的共聚物,其共聚单元为10至40重量%的丙烯酸缩水甘油酯,甲基丙烯酸缩水甘油酯或其混合物,以及70至10重量%的至少一种其它乙烯基单体 与至少一种具有至少一个缩水甘油基反应性氢原子的至少一种木材防腐剂和20至60重量%的至少一种空气反应(基于每种情况下的漆粘合剂的量)为0.01至30重量% 干燥天然或异构化脂肪酸和0至10重量%的二羧酸酐,所述漆粘合剂的平均分子量Mn为1500至15,000,酸值为3至15。 根据本发明的漆粘合剂是木材防腐剂化学固定在聚合物分子上,使得它们的释放被延迟并且保护作用被延长。 另一个优点是可以用干燥剂处理过的漆来制备干燥良好的木材防腐剂体系。
