摘要
为克服古建维修中砖地面桐油钻生常有不均匀、易产生油皮、起皮脱落的缺点 ,并提高其防水性 ,通过用不同配方钻生液涂刷砖的浸水实验 ,筛选出最佳改性桐油配方 ,为桐油 5 0 % +WD 10 10 % +醋酸丁脂 4 0 %。用此配方及有机氟配方和纯有机硅配方钻生砖样的吸水率都较低 ,而斥水性都较高 ,且持久性好。表明上述三个配方钻生液也可用于古建屋面及素砖外墙的保护。
The best formula of modified tung oil (tung oil 50%+WD10 10%+butyl acetate 40%) has been selected by the soak experiment of washing bricks with different dispensation of soak liquid for overcoming these usual flaw of nonuniformity, easy peeling, and deciduousness of tung oil soak and enhancing impermeability for repairing tiled floor in ancient architecture. The waterabsorptivity is lower, waterrepellency is higher and persistence is better for the bricks soaked by the three dispensations of modified tung oil, organic fluorine and net organosilicon. It is showed that the three dispensations of soak liquid are also useful for the protection of roofing and white brick external wall of ancient architecture.
