Therefore, water may still enter the feather linoleum in the bag, so that the floating property of the oil suction fence is lowered. Therefore, the durability and reliability of the two oil suction fences are still weak for applications where the oil suction fence is required to continue to float for more than half a month.

Description

一种耐久型羽毛吸油毡及吸油围栏的制备方法及吸油围栏结构 技术领域
本发明涉及一种吸油围栏， 尤指一种采用羽毛制备而成的耐久型羽毛 吸油围栏结构以及其制备方法， 属于环境保护领域。
说 背景技术
在油轮频繁进出的港口码头， 当油轮书装卸原油时， 可能出现少量原油 泄漏污染水体的现象。 因此， 通常会预先在油轮周围的水体上放置吸油围 栏， 既可防止油污扩散， 又可将泄露的油污吸附进吸油围栏中。
由于在大部分情况下， 油轮每次装卸原油时， 泄漏量很少。 为了提高 吸油围栏的利用效率， 减少每次铺放吸油围栏的工作量， 原油码头采用一 次铺放吸油围栏， 连续使用 15天甚至更长时间才予以更换。现在所用的吸 油围栏主要有两类： 聚丙烯熔喷毡和羽毛型吸油毡。
聚丙烯熔喷毡由聚丙烯熔喷毡和热粘合聚丙烯非织造布袋组成， 聚丙 烯材料耐紫外光日晒性能很弱， 连续多日在阳光直晒下， 聚丙烯材料的强 度会快速下降， 而聚丙烯熔喷毡自身强度不高， 在紫外光作用下， 还会进 一步下降； 加上海面上风浪的作用， 很容易破碎， 难以长时间使用。
羽毛型吸油毡是由羽毛和聚丙烯 /聚乙烯低熔点双组分纤维热粘合而 成， 自身强度比较高。 羽毛型吸油毡中作为粘结剂的聚乙烯耐紫外光降解 性能很好， 但是粘结网络中有聚丙烯组分， 这种组分在连续多日的阳光直 晒下， 强度会快速下降， 对整个羽毛吸油毡的强度也会有影响； 此外， 羽 毛型吸油毡中的羽毛原料是经过脱脂水洗的， 因此羽毛本身有吸水性； 虽 然羽毛的吸水速度很慢， 但是如果连续十多天漂浮在水面上， 仍会达到饱 和吸水程度； 同时羽毛的密度大于水的密度， 羽毛型吸油毡饱和吸水后， 可能会沉入至水面下， 失去漂浮性， 达不到拦截油污的目的； 将羽毛型吸 油毡与聚丙烯纺粘一熔喷一纺粘复合非织造布袋组合使用， 即将羽毛型吸 油毡装入聚丙烯纺粘一熔喷一纺粘复合非织造布袋中作为一个布袋整体， 可以防止水透过布袋进入羽毛吸油毡内， 但是仍存在两个问题， 其一是聚 丙烯材料耐紫外光降低性能差， 连续十多天的日光直晒， 其强度下降快； 其二是聚丙烯纺粘一熔喷一纺粘复合结构的耐水压能力有限， 通常情况下 水压力不超过 300mm水柱时， 阻水效果有保障。但是， 在连续十多天漂浮 在海面上时， 遭遇超过水压大于 300mm水柱的海浪的可能性很大， 因而， 水仍有可能进入到布袋内的羽毛吸油毡， 使吸油围栏的漂浮性下降， 因此 对于要求吸油围栏能持续漂浮使用半个月以上的场合， 这两种吸油围栏的 耐久性与可靠性仍比较弱。 发明内容
针对现有技术中存在的问题， 本发明的目的在于提供一种耐久型羽毛 吸油毡的制备方法。
本发明的另一个目的在于提供一种耐久型羽毛吸油围栏的制备方法。 本发明的第三个目的在于提供一种耐久型羽毛吸油围栏结构。 本发明 的羽毛吸油围栏结构可以在长时间段内 （至少 15天）漂浮在海面上， 用于 拦截油污扩散和吸附油污。
本发明提供的技术方案如下：
一种耐久型羽毛吸油毡的制备方法， 包括如下步骤：
(a) 拒水整理：将羽毛吸油毡浸入拒水整理剂中或者采用双面喷雾法将所 述拒水整理剂喷入到所述羽毛吸油毡内进行拒水整理； 所述羽毛吸油 毡为热粘合而成的羽毛与低熔点双组分聚丙烯 /聚乙烯纤维吸油毡； 所 述羽毛与所述聚丙烯 /聚乙烯纤维的重量比为 70〜85 : 15〜30； 所述羽 毛吸油毡的平均面密度为 150克 /米 2〜400克 /米 2；
(b) 轧辊轧压：将经过拒水整理后的羽毛吸油毡通过轧辊轧压，轧余率为 烘干后所述拒水整理剂含量占所述羽毛吸油毡重量的 5%~10%; (c)烘干焙烘： 将经过轧压后的羽毛吸油毡送入烘房， 在 120°C~135°C温 度下烘干， 然后再在 145°C~150°C温度下焙烘， 形成拒水吸油的羽毛 吸油毡。
进一步优选地， 所述拒水整理剂为石蜡-铝皂乳浊液、 脂肪酸铬络合 物溶液、 有机硅乳液中一种。
进一步优选地， 所述拒水整理剂为有机硅乳液， 所述有机硅乳液用水 稀释到 3%~7%。
一种耐久型羽毛吸油围栏的制备方法， 包括如下步骤：
(a) 以聚酯纺粘非织造布或聚酯 /聚乙烯双组分纺粘非织造布或维纶纤维 丙烯酸酯化学粘合非织造布为原料， 采用超声波粘合或缝纫线缝合制成布 袋， 所述非织造布面密度为 10克 /米 2~25克 /米 2；
(b)将所述拒水吸油的羽毛吸油毡填充到所述布袋中， 将所述布袋两端封 口制成耐久型羽毛吸油围栏。
采用上述耐久型羽毛吸油围栏的制备方法制备而成的耐久型羽毛吸油 围栏结构， 包括：
一布袋；
一填充在所述布袋中的拒水吸油的羽毛吸油毡；所述布袋的两端封口。 本发明的技术效果体现在以下几个方面：
1、 聚酯纺粘非织造布， 聚酯 /聚乙烯双组分纺粘非织造布和维纶纤维 丙烯酸酯化学粘合非织造布都具有优良的耐紫外光降解性能， 可以在较长 时间段里经受日光直晒， 并保持材料的强度； 因此吸油围栏布袋能够耐日 光照射， 而强度不会下降； 同时， 采用布袋设计又避免了日光直接晒到布 袋内的拒水吸油的羽毛吸油毡上， 可以明显降低紫外光对袋内吸油毡强度 和粘结结构的影响。
2、 布袋内的羽毛与低熔点双组分聚丙烯 /聚乙烯纤维吸油毡经拒水整 理， 具备了吸油不吸水的功能， 因此它不受海面上海浪大小的影响， 虽然 布袋材料是透水的， 但羽毛吸油围栏的漂浮性是由布袋内的羽毛吸油毡提 供的， 布袋的作用是加强强度和阻隔日光直晒到羽毛吸油毡上， 因此羽毛 吸油围栏在长时间段里 （至少 15天） 的完整性和漂浮性是可靠的。
3、 由于羽毛吸油毡的吸油量是等量聚丙烯熔喷吸油毡的 2~4倍， 因本 专利的耐久型羽毛吸油围栏作为长时间段里的防护性材料， 即使在出现意 外的较大量原油泄漏的情况下， 由于其吸油量大， 因而可提供更大的吸附 油污的能力， 可以很好适应长时间段里可能出现的各种复杂情况。 附图说明
