2、 Main functions and uses: titanate coupling agent, both aluminate and titanate coupling agent characteristics. Due to the characteristics of bimetallic central atomic structure, it shows more excellent coupling effect than traditional coupling agents such as pure titanate and aluminate, which greatly improves the compatibility of inorganic and polymer, reduces the viscosity of filler system, increases the filling amount of inorganic filler in polymer, and improves the processing performance and physical and mechanical properties of the composite.
At present, it is mainly used for the surface activation of inorganic fillers such as calcium carbonate, talc, wollastonite, kaolin, etc. compared with the coupling agent of single metal center atom such as traditional titanate, aluminate, etc., it has light color, solid state, high coupling activity, and is convenient for transportation.
Especially suitable for: PVC / calcium carbonate, PP / Talcum powder and other conventional polymer filling systems. In PP / Talcum powder filling system, the composite modification effect reaches or exceeds the level of kh-550560, which has significant cost advantage. In addition, the product is also suitable for paint, ink, color masterbatch and other systems, to improve pigment dispersion and color development.
3、 Usage and dosage: generally in high-speed mixer, preheat the filler in high-speed mixer for 5-10 minutes (90-100 ℃), measure and add the product, and finally mix for 10 minutes (90-100 ℃) at high speed to discharge the material. Recommended dosage of composite coupling agent: 0.8% ~ 1.5% of the filling amount, which can activate the filler and be directly used in the resin.
