This Small Business Innovation Research (SBIR) Phase I will develop coatings containing post-consumer commingled polymer (PCCP) waste. The very large volume of plastics in the waste stream is a significant environmental burden. The use of plastics is increasing rapidly due to the advent of new resins and increased efficiencies in polymer processing. Concurrently environmentally benign coatings are needed to protect the civil infrastructure from the effects of corrosion. Increasingly restrictive environmental regulations regarding volatile organic compounds (VOC's) may soon ban the use of existing coating systems that contain high levels of VOC's. This SBIR Phase I will produce a composite polymer powder containing PCCP and a commercially available ethylene methacrylic-acid copolymer (EMAA). The composite powder will be used to deposit barrier comings onto steel substrates using a thermal spray process. Specific commercial applications are expected to include include: i) bridge surfaces, ii) pipe coatings and linings, iii) flood-gates, iv) chemical and/or water containment, v) sealers for hazardous waste containment, vi) domestic waste containment, vii) transfer chutes, and viii) propeller blades.

小企业创新研究（SBIR）第一阶段将开发含有消费后混合聚合物（PCCP）废物的涂料。 废物流中大量的塑料是一个重大的环境负担。 由于新树脂的出现和聚合物加工效率的提高，塑料的使用正在迅速增加。 同时，需要环境友好的涂层来保护民用基础设施免受腐蚀的影响。 关于挥发性有机化合物（VOC）的日益严格的环境法规可能很快禁止使用含有高水平VOC的现有涂料体系。 SBIR第一阶段将生产一种含有PCCP和市售乙烯甲基丙烯酸共聚物（EMAA）的复合聚合物粉末。 该复合粉末将用于使用热喷涂工艺在钢基底上存款屏障涂层。 具体的商业应用预计包括：i）桥梁表面，ii）管道涂层和衬里，iii）防洪闸，iv）化学品和/或水的密封，v）危险废物密封，vi）生活废物密封，vii）转移槽，和viii）螺旋桨叶片。
