通过丙烯酸预聚物与碱式水杨酸锌之间的酸碱中和反应合成了自抛光型丙烯酸锌树脂,并用红外光谱表征其结构。以该丙烯酸锌树脂为基料,添加25%(质量分数)氧化亚铜及少量有机防污剂制成自抛光型防污漆,相比传统防污漆,氧化亚铜用量减少15%以上。通过对该防污漆的常规性能、贮存稳定性、耐阴极剥离性能及其防污性能的测试,证实了它是一种低成本、高性能的防污漆。 相似文献

有机锡高聚物防污涂料目前在世界上是一种新型的防污涂料,该涂料与传统防污涂料的根本区別是:将防污活性基团通过化学反应接在丙烯酸树脂上,在该树脂中加入水敏感性颜料。填充料、阻渗剂、稳定剂等调配而成,是属于水解冲蚀型防污涂料。该防污涂料在船舶航行中,漆膜表面能逐渐被水解腐蚀而起到防止海生物污损及漆膜拋光作用,并直至漆膜全部被磨蚀完止。所以能充分利用毒料,有效地防止海生物污损,保持 相似文献

研制了一种柔韧性优异适用于弹性体基材表面的防污涂料。合成具有自抛光性能的柔性丙烯酸硅烷酯基体树脂,采用加入低分子量韧性树脂外增塑手段进一步增加基体树脂的柔韧性,采用丙烯酸硅烷酯树脂和韧性混合树脂制备了柔性自抛光防污涂料。实验结果表明,丙烯酸硅烷酯基体树脂的玻璃化转变温度-20℃时,具有较好的物理机械性能。基体树脂与韧性树脂比例为7:3时,此时共混树脂的缺陷相对其他配比最小,树脂相容性最好。制备的防污涂料柔韧性为1级,在弹性体基材表面附着力达到4.0MPa,经过60天测试,涂层吸水率在1.1%~1.2%之间,在合理范围内。浅海浸泡挂板36个月具有良好防污效果。研制的柔性自抛光防污涂料,具有优异的防污性能,可满足弹性体基材表面对海洋污损防护需求。 相似文献

将有机硅材料和防污剂共聚接枝到丙烯酸树脂中,制备了一种接枝BIT(1,2-苯并异噻唑啉-3-酮)的、具有协同防污机制的有机硅基丙烯酸防污树脂。通过红外光谱、凝胶渗透色谱对树脂的结构和相对分子质量进行测定,并对树脂分别进行了接触角、静态海水浸泡质量损失、抑藻性能测试以及实海挂板实验。结果表明:树脂表面接触角随着有机硅含量的增加而增加;在海水中,接枝到树脂上的BIT-W可以缓慢稳定地释放,其质量损失曲线近似呈线性变化,平均质量损失在0.03~0.09 mg之间;树脂对旋链角毛藻和小球藻均具有良好的抑制作用,调整BIT-W含量使得树脂对2种藻类的抑制率分别达到了70.8%和82.7%。此研究中的防污树脂合成方法简单、原料成本低廉,同时引入防污剂和有机硅基材料,赋予防污树脂在静态水和动态水中良好的防污性能。 相似文献

Environmental concerns have led to a progressive withdrawal of antifouling paints containing organotin derivatives. Resanbio?,
a cooperative research program, plans to develop new antifouling paints that are more compatible with living species. In the
first stage, we studied specific acrylic polymers with a variable hydrophilic/hydrophobic balance and, in some cases, pendant
hydrolyzable functions. To evaluate the ability of these materials for hydrolysis, biocides release, and erosion, test panels
with formulated films were prepared and immersed in sea water. An analytical protocol was established to characterize the
polymeric material, to reveal chemical reactions that occur during erosion and antifouling action, and to understand the influence
of the resin chemical structure on the paint’s antifouling efficiency. The degradation of these binders was revealed by the
appearance of a product resulting from the hydrolysis. This product was identified and quantified by GC-MS. The release of
cuprous oxide as model molecule, due to its water solubility and biocide activity, was quantified by inductively coupled plasma.
The different processes used are explained and illustrated by an example of an efficient, erodable, antifouling paint following
22 months of immersion. 相似文献

Coatings with a self-generating hydrogel surface for antifouling 总被引:1,自引:0,他引:1
We prepared a coating by mixing a polyfunctional axiridine cross-linking agent and a self-polishing resin pre-synthesized via the polymerization of methyl methacrylate (MMA), acrylic acid (AA) and tributylsilyl methacrylate (TBSM). The coating can be easily applied on a surface to form a cross-linked polymer film by conventional brushing or spraying method. After immersing it into seawater, the film self-generates a thin soft and dynamic layer of hydrogel at the water-contacting surface because of the hydrolysis of TBSM. Such a hydrogel-formation process continues after gradual corrosion and detachment of each top hydrophilic layer. This hydrogel-formation and self-peeling property makes it ideal in various antifouling applications. In the current study, besides the synthesis and preparation of this novel kind of coatings, we focused on the correlation between the TBSM content and the antifouling property by using contact angle, water-absorption, and antifouling measurements. The results of immersing different coatings in shallow submergence for two months reveal that the addition of more TBSM leads to a more hydrophilic surface and a better antifouling property. 相似文献
