一种硅氧烷杂化防腐蚀涂料
摘要：
本发明涉及一种硅氧烷杂化防腐蚀涂料，在每100质量份的A组分中，环氧树脂20份、改性树脂8～12份、颜料和填料50～55份、助剂1～3份、余量为混合溶剂，其中，环氧树脂为低分子量的双酚A型或双酚F型液体环氧的一种或几种；改性树脂为有机硅改性环氧树脂，它是以正硅酸乙酯42份、苯基三甲氧基硅烷8份、γ－氨基丙基三烷氧基硅烷4.5份、水4份、盐酸1.5份、异丙醇25份、E-51环氧树脂10份和丙酮5份为原料制得的；在每100质量份的B组分中，聚酰胺50份、氨基硅氧烷树脂10～15份、余量为混合溶剂。A、B组分配套适宜，所得涂料能够通过ISO20340的技术要求，为海洋工程提供了长效保护。
摘要（英）：

The invention relates to a siloxane hybrid anticorrosive paint. Every 100 parts by mass of component A is composed of 20 parts of epoxy resin, 8-12 parts of modified resin, 50-55 parts of pigment and filler, 1-3 parts of assistant and the balance of mixed solvent, wherein the epoxy resin is composed of one or more of low-molecular-weight bisphenol A or bisphenol F liquid epoxy resins; and the modified resin is an organic silicon modified epoxy resin prepared from 42 parts of ethyl orthosilicate, 8 parts of phenyltrimethoxysilane, 4.5 parts of gamma-aminopropyl trialkoxysilane, 4 parts of water, 1.5 parts of hydrochloric acid, 25 parts of isopropanol, 10 parts of E-51 epoxy resin and 5 parts of acetone. Every 100 parts by mass of component B is composed of 50 parts of polyamide, 10-15 parts of aminosiloxane resin and the balance of mixed solvent. By properly matching the components A and B, the obtained paint can satisfy the technical requirements in ISO20340, and provides long-acting protection for ocean engineering.
