基于树枝状聚合物材料的环保型绝缘浸渍漆性能优异

基于树枝状聚合物材料的环保型绝缘浸渍漆性能优异传统无溶剂环保型浸渍漆主要由合成树脂、固化剂和活性稀释剂组成。其特点是：①固化快；②流动性和浸透性好；③绝缘整体性好；④固化过程挥发物少。但目前通用的稀释剂如苯乙烯、乙烯基甲苯等存在如下问题：①毒性强；②挥发性大；③环境污染严重等，制约了无溶剂浸渍漆的广泛应用。树枝状聚合物具有三维的球状立体结构、相对较低的链间缠绕程度和大量的活性端基而具有①高溶解度、②低黏度、③高热稳定性、④良好电绝缘性等优点。开发低粘度、易加工成型和良好相容性的树枝状聚合物树脂材料代替稀释剂，可提高无溶剂浸渍漆环保性能和成型加工性能，同时浸渍漆贮存稳定性好，挥发小，无毒，污染小，相对传统漆具有更大的优势。最新第四代高分子材料-高性价比树枝状聚合物材料的专业制造商—威海晨源分子新材料有限公司Environmentfriendlydendrimerbasedinsulationvarnishhavegoodperformance.Conventionalenvironmentfriendlyvarnishmainlycomposedbysyntheticresin,curingagentsandreactivediluent.Itscharacteristicsare:①fastcuring;②goodfluidityandpermeability;③insulationintegrityisgood;④lessvolatileincuringprocess.However,thecurrentgeneraldiluent,suchasstyrene,vinyltoluene,etc.havefollowingproblems:①hightoxicity;②largevolatility;③seriousenvironmentalpollution,limitingapplicationofvarnishwithoutsolvent.Dendrimerissphericalandthree-dimensionalstructurewithlowdegreeofinter-chainwindingandalargenumberofreactiveendgroups,andalsohaving①ahighsolubility,②lowviscosity,③goodthermalstability,④goodelectricalinsulatingpropertiesandsoon.Developmentofdendriticpolymerresinmaterialswithlowviscosity,easyprocessingandgoodcompatibilityinsteadofdiluent,canimprovesolvent-freevarnishenvironmentalperformanceandprocessingbehavior,whilevarnishhavegoodstoragestability,lowvolatile,non-toxic,littlepollution,comparedwithtraditionalpainttheyhaveagreateradvantage.WeihaiCYDendrimerTechnologyCo.Ltd.-ProfessionalManufacturerforlowcostdendriticpolymers.-Thenewest4thclasspolymers.
