SBIR Phase I: Environmentally Acceptable Antifouling Paint

9560960狄克逊 这个小企业创新研究第一阶段项目旨在发现一个根本的新方法来解决比诺亚更古老的问题;即如何以环境可接受的方式保持船底不受生物污染。 自从诺亚第一次使用沥青以来，人类一直依赖有毒物质来抑制生物污垢。 不幸的是，这些物质往往会在海洋环境中持久存在。 人类对海洋资源的日益利用往往使问题复杂化，以至于今天只允许从一个非常短的有毒物质清单中选择使用，甚至从这个清单中选择物质也是不可取的。 本研究的目的是证明使用持久性毒物是不必要的。 提出了光毒性表面的实验室配方以及它们在海洋环境中抗生物污损的测试。 如果成功的话，这种方法将在很大程度上取代依赖铜和有机锡化合物等持久性有毒物质的涂料。 底漆，这代表了数百万美元的全球市场，主要是制造和销售的外国公司使用的技术，这是一个世纪。 他们的产品是溶剂型的，使用和去除都很危险。 油漆碎片必须作为危险废物收集和处理。 用一种更环保的技术取代这种技术是非常可取的，随着一个又一个国家禁止有毒物质用于人体，这种技术变得越来越重要。

9560960 Dixon This Small Business Innovation Research Phase I project seeks to discover a fundamental new approach to a problem older than Noah; namely, how to keep the bottoms of boats free from biofouling in an environmentally acceptable manner. Since Noah first used pitch, man has relied on toxic materials to inhibit biofouling. Unfortunately these materials have tended to persist in the marine environment. Increased use of marine resources by man has tended to compound the problem to the point where today selection for use from only a very short list of toxicants is permitted, and even choosing substances from this list is undesirable. The objective of this research is to demonstrate that the use of persistent toxicants is unnecessary. Laboratory formulation of phototoxic surfaces are proposed as well as tests of their resistance to biofouling in the marine environment. If successful, the approach will largely replace coatings which rely on persistent toxicants such as copper and organotin compounds. Bottom paint, which represents a multimillion dollar worldwide market, is primarily manufactured and sold by foreign firms using technology which is a century old. Their products are solvent based and hazardous to apply and remove. Paint chips must be collected and disposed of as hazardous waste. Replacing this technology with one that is more environmentally acceptable is very desirable and is becoming increasingly essential as country after country bans toxicants for antifouling.
