相容剂概述:

An overview of compatibilizer:

借助于分子间的键合力，促使不相容的两种聚合物结合在一体，进而得到稳定的共混物的助剂称之为相容剂，又称增容剂、高分子偶联剂，是一种新颖的塑料助剂，这里是指高分子增容剂PE-g-ST、PP-g-ST、ABS-g-MAH、PE-g-MAH、PP-g-MAH等，应用在塑料改性中，得到性能很好的共混性材料。

With the aid of intermolecular bonding force, the incompatible two kinds of polymers are combined in one, and the additives of the stable blends are called compatibilizer, also called compatibilizer and polymer coupling agent. It is a new kind of plastic additives. This is the polymer compatibilizer PE-g-ST, PP-g-ST, ABS-g-MAH, PE-g-MAH, PP-g-MAH. And so on, in the application of plastic modification, get good blending material.

目前比较好的相容剂通常以马来酸酐接枝，马来酸酐单体和其它单体比较极性比较强，相容效果比较好,马来酸酐接枝相容剂通过引入强极性反应性基团，使材料具有高的极性和反应性，是一种高分子界面偶联剂、相容剂、分散促进剂。主要用于无卤阻燃、填充、玻纤增强、增韧，金属粘结、合金相容等，能大大提高复合材料的相容性和填料的分散性，从而提高复合材料机械强度。

At present, the good compatibilizer is usually grafted with maleic anhydride. The maleic anhydride monomer and other monomers have strong polarity and better compatibility. The maleic anhydride graft compatibilizer can make the material with high polarity and reactivity by introducing the strong polar reactive group. It is a kind of polymer interface coupling agent, compatibilizer and dispersing agent. Accelerant. It is mainly used for halogen-free flame retardancy, filling, glass fiber reinforcement, toughening, metal bonding and alloy compatibility, which can greatly improve the compatibility of the composite and the dispersity of the filler, thus improving the mechanical strength of the composite.

马来酸酐接枝相容剂可改善无机填料与有机树脂相容性，提高产品的拉伸、冲击强度，实现高填充，减少树脂用量，改善加工流变性，提高表面光洁度。相容剂应用范围：
