77－4长效防污漆研究

Study of 77-4 long-life antifouling paint

以聚异丁烯为基料，Ｃｕ＿２Ｏ为毒料，进行配方设计和筛选，研制成功７７－４聚异丁烯长效防污漆。经实船试验，其性能良好，防污期效为３年左右。可用于船底及水下橡胶底村表面的防污。

The development of 77-4 polyisobutylene antifouling paint with a long life hdve success which is made of polylsobutylene as a resin and Cu_2O as a loxic material.Service tests on ships of the paint indicate that the paint has good performance with an antifouling term of about 3 yedrs and can be used for an antifoul-ing paint for bottom surfaces and surfaces of underseawater rubber substance.
