无机防静电热控涂层制备及性能研究
Preparation and Properties Study of Inorganic Antistatic Thermal Control Coatings
摘要
Abstract
The Al-doped ZnO(AZO)antistatic thermal control filler was prepared by co-precipitation method with potassium silicate used as the binder.The influence of doping ratio,pigment-to-fill ratio and other factors on the resistivity and thermal control performance of the coating was studied,and the inorganic antistatic thermal control coating was prepared.The microstructure and phase composition of fillers and coatings were characterized by SEM,XRD,and 3D measurement laser microscope,and the resistivity and thermal control properties of coatings were evaluated by contact resistance tester and spectrophotometer.The results show that the coating has a dense surface,uniform thickness,good film-forming properties,good adhesion to the substrate(level 1),and excellent thermal control performance(αs=0.19±0.02;εH=0.92±0.02),low resistivity[(3.0-18.0)x105 Ω·m],and excellent space environment adaptability,which has great application prospects in the field of spacecraft anti-static thermal control.关键词
