Important Additives in Modern Industry - Silane Coupling Agents
Dec 13, 2024
Silane coupling agents are a class of special compounds containing silicon elements, mainly composed of silicon atoms and organic groups, which can establish a molecular bridge between organic and inorganic materials, thereby significantly improving the interfacial bonding performance of the two. Silane coupling agents are widely used in plastics, rubber, coatings, adhesives and composite materials, and are an indispensable and important auxiliary agent in modern industry.
Structure and working principle of silane coupling agent
Silane coupling agent usually consists of three parts:
Siloxy part (Si-OH or Si-OR)
Siloxyl group generates silanol through hydrolysis, and condenses with hydroxyl groups on the surface of inorganic materials (such as glass fiber, silicate or oxide) to form a strong chemical bond.
Organic functional group
This part can be amino, epoxy, vinyl, methacryloyl, etc., which can react with organic materials (such as resin or rubber) to achieve the combination of the two.
Silane main chain
Silicon atoms act as a bridge through the connection of organic groups and inorganic groups to complete the combination between organic and inorganic materials.
Working Principle
The effect of silane coupling agent mainly depends on its amphoteric chemical properties. Through hydrolysis and condensation reactions, silane coupling agent can form a stable monolayer on the surface of inorganic materials, thereby improving the interfacial bonding strength of the materials. In addition, its organic groups combine with organic polymers through chemical reactions, significantly improving the mechanical properties and stability of composite materials.
As an important bridge for the combination of organic and inorganic materials, silane coupling agent plays a vital role in the fields of plastics, rubber, coatings, composite materials, etc. due to its excellent performance.
