Provided is a silyl polymer-based antifouling coating composition that is capable of forming a coating film in which cracking is inhibited from occurring for a long period from the early stage of immersion in seawater and fresh water and enables to maintain excellent coating film consumption for a long term. The antifouling coating composition includes: a copolymer (A) containing a structural unit (a-1) derived from styrene or the like, a structural unit (a-2) derived from glycidyl (meth) acrylate, and optionally a structural unit (a-3) derived from another ethylenically unsaturated monomer; a polymer (B) containing a structural unit (b-1) derived from a monomer represented by the following Formula (b1) :
wherein X is a hydrogen atom or a carboxyl group; R1 is a hydrogen atom or a methyl group; R2 to R6, which may be the same as or different from each other, are C1-C6 straight or branched chain alkyl; and n is an integer of 0 or 1 or more; and an antifoulant.
本发明提供了一种以硅烷基聚合物为基础的防污涂料组合物,该组合物能够形成涂膜,从浸入海水和淡水的早期阶段开始,长期抑制裂纹的产生,并能长期保持优异的涂膜消耗性。该防污涂层组合物包括:共聚物(A),其中包含一个由苯乙烯或类似物衍生的结构单元(a-1)、一个由(甲基)丙烯酸缩水甘油酯衍生的结构单元(a-2),以及可选地一个由另一种乙烯基不饱和单体衍生的结构单元(a-3);聚合物(B),其中包含一个由下式(b1)代表的单体衍生的结构单元(b-1):
其中 X 是氢原子或羧基;R1 是氢原子或甲基;R2 至 R6(可以相同或不同)是 C1-C6 直链或支链烷基;n 是 0 或 1 或更多的整数;以及防污剂。
