Application of silane coupling agent in glass fiber industry

    The rigidity of the glass fiber treated by silane coupling agent is improved, and the cutting property of the glass fiber is also improved obviously. At the same time, the defects formed in the drawing process of the glass fiber can be eliminated, so as to ensure the surface integrity of the glass fiber, protect the quality of the glass fiber, prevent the damage of the glass fiber in the processing process, and improve the tensile strength of the glass fiber itself The most important role of coupling agent in glass fiber reinforced composites is to strengthen the bond between glass fiber and resin, which prevents the quality degradation caused by the invasion of moisture. On the one hand, silane can form covalent bond molecular layer with the surface of glass fiber, which can prevent the invasion of water molecules to the greatest extent; on the other hand, the organic characteristic group of silane coupling agent can react with the resin and play a coupling role, so it can improve the adhesion between glass fiber and resin, greatly improve the mechanical properties of glass fiber reinforced composites, and also improve the mechanical properties of glass fiber reinforced composites It can effectively reduce the decrease of adhesion caused by water intrusion, and maintain or significantly improve the wet mechanical properties of the composites.
