摘要：以油脂二聚酸为基体,银包铜粉及银粉为导电填料,制备了导电性能优良的单组份导电涂料,研究了导电涂料固化产物的电性能、力学性能、抗冲击性。当银包铜粉/银粉质量达到导电涂料质量的60%时,固化产物体积电阻率可达6.55×10-4Ω·cm,附着力一级,冲击强度≥50 kg·cm,热分解温度达到400℃,玻璃化转变温度为105.6℃。本导电涂料适用期为8 h。
A kind of conducting coating with excellent electric conductivity is prepared with fatty acid dimmers as matrix resin and silver coated copper powder and silver powder as conducting fillers. The electrical conductivity, mechanical properties and impact resistance properties are studied. By adding 60% mass fraction of conducting fillers, the cured films with good adhesion to substrates and impact strength no less than 50 kg·cm have 6. 55 × 10- 4/ Ω·cm of volume resistivity,340. 7℃ of heat decomposed temperature and 105. 6℃ of the glass transition temperature. The pot life of the conductive coating is 8 hours.
