Glass fiber using the silane coupling agent, has the following benefits:
1. Can prevent water infiltration glass fiber surface and the polymer interface, greatly improving the aging resistance and water resistance of glass fiber products.
2. Strengthen the bond between glass fiber and polymer resin, so the composite material when subjected to stress, stress can be smoothly passed on from the matrix resin to glass fiber, enhanced composite materials tensile, compression, bending and impact the mechanical properties.
3. Can also increased the strength of glass afternoon monofilament within itself.Silane on the surface of the glass fiber can be repaired and filled glass fiber in the process of drawing the small crack, general glass fiber treated with silane coupling agent, monofilament strength can be increased by 20%.
4. Can greatly improve the electrical properties of composite materials exposed to moisture.Dielectric constant and resistance were improved greatly.
Silane role behavior of reactive groups, summarized as follows: silane hydrolysis groups with inorganic glass fiber reactive, provides the silane - glass combination of all kinds of behavior.
