助剂对厚浆型环氧涂料流变性能的影响

环氧树脂涂料由于具有突出的附着力，良好的耐蚀性，品种和性能的多样性等优点，在涂料工业中得到了广泛应用。然而，由于厚浆型环氧涂料内颜填料含量高、粘度大、流平性差等弊病，严重影响了其装饰作用，降低了保护作用。通过助剂的添加，可以很大程度地改变这些缺陷。本选择了流变助剂中的有机膨润土、BYK-410、MT和流平剂中的BYK-354，并通过改变其用量，检测其对环氧涂料性能的影响，尤其是对涂料流挂性能、流平性能和粘度的影响。

Modifiers Effect to Rheological Characteristics of the Mastic Epoxy Paints

Mastic epoxide coating is because of its outstanding adhesion, excellent corrosion resistsnce, lots of types and performances etc. Got the extensive application in the coating industry. However, there are lots of pigment and extender bodiness high consistence, poor flow and leveling in the epoxy coatings. Cause the epoxy coatings don't be widely used .When given modifiers, this shortage can be avoided. So it is very important that use the most appropriate rheology modifier. This paper alternative organic bentonite, BYK-410, MT and BYK-354, though change their using, then text the properties of the epoxy coatings. The most important is to text leveling , sag control and consistency. Then choice one or two rhcology modifier, leveling modifier with excellent performanceang good price.
