【摘要】：本文采用摻雜法制備了金屬（銅、鎳）粉末摻雜的不同聚合物體系（醇酸樹脂、環(huán)氧樹脂、丙烯酸樹脂）的導(dǎo)電涂料。首先用自制超分散劑對(duì)金屬粉末（銅粉、鎳粉）進(jìn)行超分散改性，同時(shí)通過超分散劑的具有還原性質(zhì)的三乙醇胺末端基實(shí)現(xiàn)對(duì)銅粉導(dǎo)電涂料的抗氧化改性；然后優(yōu)化了導(dǎo)電涂料的制備工藝，得到性能穩(wěn)定的導(dǎo)電涂料。 利用丙烯酸樹脂、環(huán)氧樹脂、醇酸樹脂作為成膜物質(zhì)，，銅、鎳粉作為導(dǎo)電填料，進(jìn)行配方試驗(yàn)，通過不同導(dǎo)電填料添加量、不同超分散劑添加量、不同防沉劑添加量以及不同涂膜厚度對(duì)涂層導(dǎo)電性能及物理機(jī)械性能的影響分析，得到優(yōu)化的導(dǎo)電涂料配方及性能。 研究結(jié)果表明，丙烯酸樹脂體系導(dǎo)電涂料具有良好的導(dǎo)電性能和機(jī)械性能；環(huán)氧樹脂體系導(dǎo)電涂料存在韌性不足、固化溫度高、導(dǎo)電性能差等缺點(diǎn)；醇酸樹脂體系導(dǎo)電涂料導(dǎo)電性能優(yōu)異，但由于醇酸樹脂中往往會(huì)殘留有一些雙鍵、羥基等，常常影響其理化性能，存在完全干燥時(shí)間長，涂料長期放置后導(dǎo)電性能下降等缺點(diǎn)。
[Abstract]:In this paper, conductive coatings of different polymer systems (alkyd resin, epoxy resin, acrylic resin) doped with metal (copper, nickel) powder were prepared by doping method.Firstly, the metal powder (copper powder, nickel powder) was modified by self-made hyperdispersant, and the oxidation resistance of copper powder conductive coating was modified by triethanolamine terminal group with reducing property of hyperdispersant.Then the preparation process of conductive coatings was optimized to obtain stable conductive coatings.Using acrylic resin, epoxy resin, alkyd resin as film-forming material, copper and nickel powder as conductive filler, the formula was tested by adding different amount of conductive filler and hyperdispersant.The effects of different amount of antisettling agent and different thickness of coating film on the conductive and mechanical properties of the coatings were analyzed. The optimized formulation and properties of the conductive coatings were obtained.The results show that the conductive coatings of acrylic resin system have good electrical and mechanical properties, and the conductive coatings of epoxy resin system have the disadvantages of poor toughness, high curing temperature and poor electrical conductivity.The conductive coatings of alkyd resin system have excellent conductive properties, but because of the presence of some double bonds and hydroxyl groups in the alkyd resins, the physical and chemical properties of the coatings are often affected, the complete drying time is long, and the conductive properties of the coatings are decreased after a long period of time.
