The surface treatment of glass fibers by coupling agents is relatively mature. For the surface modification of potassium titanate whiskers, the relatively mature surface modification technology of glass fiber systems is generally used in literature reports. There is a big difference in the traditional treatment, and the ideal effect is often not obtained. The most commonly used coupling agents are alkoxysilanes containing organofunctional groups.

The ideal state of the whisker reinforced resin is that the whiskers should be uniformly distributed in the matrix, the whiskers should be separated from each other, and be well wetted by the matrix resin. In order to promote the dispersion of the inorganic whiskers in the organic matrix, and to give the whiskers and 61 Yangning, and other silane coupling agents a certain force between the surface treatment of the whiskers and the application of the matrix, it is necessary to use a coupling agent to conduct the whiskers. Surface modification. It can be clearly seen from the table that the effect of the silane coupling agent CFS-838 is more suitable for the potassium titanate whisker filled polypropylene system, it can effectively improve the interface between the resin and the whiskers, making the strengthening effect of the whiskers get more full play.

As an important additive, silane coupling agent helps to improve some physical and chemical properties of the material, such as the heat resistance, moisture resistance and processing properties of rubber, the mechanical properties of resin composites, and the adhesive strength of adhesives. Studies have shown that the surface treatment of whiskers by coupling agents has a significant effect on improving the mechanical properties of resin materials, and can also effectively improve the compatibility of organic and inorganic phases.
