喷涂型无溶剂重防腐涂料的制备和性能研究

Study Preparation and Performance of Spraying Type Solvent-free Heavy Corrosion Coating

为了制备一款喷涂型无溶剂重防腐涂料,本研究以双酚F环氧树脂、间苯二酚环氧树脂、腰果酚缩水甘油醚为基料主要成分,以自制混胺为固化剂,在此基础上添加颜填料、助剂,经分散、研磨、过滤制得。经测试本产品混合粘度为2590 MPa·s-1、热变形温度为94℃、附着力为18.5 MPa、耐沸水、耐盐水、耐热原油、耐酸碱、耐中性盐雾性能优越,可进行喷涂,适合工业重防腐领域大面积应用。

In order to prepare a spraying type heavy anticorrosive coating,using BPF epoxy resin,resorcinol epoxy resin,cashew phenol glycidyl ether as the main ingredients of the base,self-made mixed amine as the curing agent,adding pigments,fillers and additives,the materials were dispersed,grinded and filtered. The mixed viscosity of this product was 2590 MPa·s-1,the thermal deformation temperature was 94 ℃,the adhesion was 18. 5 MPa,the resistance to boiling water,salt water,heat crude oil,acid and alkali,neutral salt spray performance was superior,it can be sprayed,this product can be used for large area application in industrial heavy corrosion.
