防静电型水性阻尼涂料的制备及其性能研究
Preparation and Properties of Antistatic Water-Based Damping Coatings
摘要
Abstract
Noise pollution seriously affects people's quality of life.As an effective vibration and noise reduction material,damping coatings are developing in the direction of high damping performance,wide temperature range and functionalization.The electrical insulation of water-based damping coatings makes static electricity accumulate on the surface of materials,which limits the application of damping coatings in specific environments.Polyaniline modified water-based polyurethane/acrylate resin(WPUA-PANI)was selected as the base resin,sericite as the damping filler,and other additives were added to prepare a series of water-based damping coatings with antistatic properties.The influence of the mass ratio of sericite to base resin on the structure and properties of coatings was studied.The results show that the coatings prepared are pseudoplastic fluids and have good anti-sagging properties.When the mass ratio of sericite to base resin is 30/70,the water contact angle and resistivity are 110.9° and 7.24×104 Ω·cm,respectively,and the maximum effective damping temperature range is 122℃,which is obviously higher than that of the base resin.The coating has good damping property,antistatic property,water resistance,and solvent resistance.关键词
