一、引言油漆催干剂是一种能促使漆膜干燥的物质,俗名燥液。它能促进干性油膜的吸氧及聚合作用。例如:亚麻仁油未加催干剂时,其涂膜要6～8日后才干结,且干后不爽。加入催干剂后,在15小时后即可干结成膜,油膜光滑爽快不粘手,干燥成膜的时间,比没有催干剂快,这样便于施工,又防止了灰沙雨露的沾污和破坏。一般使用的油漆催干剂,主要是钴、锰、铅、锌、钙的环烷酸盐。俗称钴皂、锰皂、铅皂……上述五种金属皂。按照它们在油漆催干剂中的作用可分为二类,即氧化聚合催干剂——钴皂、锰皂、铅皂和辅助催干剂——锌皂、钙皂。
First, the introduction of paint driers is a substance that can make the paint dry, common name of liquid. It can promote dry oil film oxygen and polymerization. For example: linseed oil without driers, the coating to 6 to 8 days after the dry knot, and dry uncomfortable. After adding the drier, the film can be dry-formed in 15 hours, the film is smooth and non-sticky, and the time for drying and film formation is faster than that without the drier, which is convenient for construction and prevents the dust, damage. The general use of paint driers, mainly cobalt, manganese, lead, zinc, calcium naphthenate. Commonly known as cobalt soap, manganese soap, lead soap ... ... The above five kinds of metal soap. According to their role in paint driers can be divided into two categories, namely oxidative polymerization driers - cobalt soap, manganese soap, lead soap and auxiliary driers - zinc soap, lime soap.
