                     摘 要:参考 ISO 12944 耐久性要求、腐蚀环境分类标准,综合分析已有涂料涂层体系技术指标、
                 历年积累的腐蚀老化数据及涂料供应商提供的试验数据,确定了适用于工程机械涂装的聚天门冬氨
                 酸酯聚脲(PAE聚脲)涂料涂层体系。参考江苏省地方标准,结合涂装生产线实际情况,通过理论计算
                 确定 PAE 聚脲涂料环保、消防要求。根据工程机械产品涂装特点,确定 PAE 聚脲涂料施工性能要求。
                 参考现有工程机械涂料技术要求,确定 PAE 聚脲涂料复合涂层性能指标。并按照涂料选择“五步法”
                 对聚天门冬氨酸酯聚脲涂料进行初步试验和复合涂层试板试验。基于聚天门冬氨酸酯聚脲涂料的
     健           优势及相关文献介绍,可以在工程机械涂装推广使用。

                      Abstract: Referring  to  the  durability  requirements  and  corrosion  environment
                 classification standards of ISO 12944,a comprehensive analysis of the technical indicators of
                 existing  coating  systems,accumulated  corrosion  aging  data  over  the  years,and  test  data

                 provided  by  coating  suppliers  had  been  conducted  to  determine  the  polyaspartate  polyurea
                (PAE)coating system suitable for engineering machinery painting. Based on local standards

                 in Jiangsu Province and the actual situation of the coating production line,he environmental
                                                                                          t
                 protection and fire protection requirements for PAE polyurea coatings were determined through
                 theoretical calculations. The construction performance requirements for PAE polyurea coatings
                 were  determined  based  on  the  coating  characteristics  of  construction  machinery  products.
                 Referring  to  the  existing  technical  requirements  for  engineering  machinery  coatings,the
                 performance  requirements  of  PAE  polyurea  coating  composite  coatings  were  developed. The
                 preliminary test of polyaspartate polyurea coating and composite coating plate test were carried
                 out  according  to  the  five-step  method  of  coating  selection. Based  on  the  advantages  of
                 polyaspartate  polyurea  coating  and  related  literature  introduction,it  could  be  used  in
                 construction machinery coating.
