Silane coupling agent is an important chemical reagent, and its molecular structure is generally Y-R-Si(OR)3 (Y in the formula: organic functional group; SiOR: siloxyl group). Silane coupling agents are mainly used in glass fiber reinforced plastics. Siloxy groups have reactivity to inorganic substances, and organic functional groups have reactivity to organic substances. Therefore, when the silane coupling agent is between the inorganic and organic interfaces, a bonding layer of organic matrix-inorganic matrix is formed, which makes the silane coupling The agent can be coupled with organic and inorganic substances to improve the properties of materials, and can be widely used in the production and processing of rubber, plastics, filled composite materials, coatings, adhesives and sealants.
Features
Modification of high-quality composite materials: Silane coupling agents greatly improve the dispersion of resins and coatings, while also improving strength, water resistance, cold resistance and adhesion.
Modified resin: Silane coupling agent can improve the adhesion of resin to organic materials and impart low temperature, low moisture curing, and improve weather resistance, heat resistance and acid resistance, solvent resistance.
Application
Surface treatment: Silane coupling agent can improve the adhesion between glass fiber and resin, and can greatly improve the strength, electrical properties and hydrophobic properties of the material. Silane coupling agents that have been widely used in industrial production include vinyl silane, amino silane and methacryloxy silane.
Filled plastics: Silane coupling agents can improve the dispersion, adhesion, electrical properties, mechanical properties and stability of fillers in resins.
Additives for polymer materials: Silane coupling agents can be used as tackifiers for sealants, adhesives and coatings, which can improve the strength, water resistance and weather resistance of materials, give full play to their functions and reduce costs.
Textile auxiliaries: Silane coupling agents can effectively improve the performance of textiles, making textiles soft, elastic, waterproof and antistatic, resistant and comfortable to wear.
Biological application: Silane coupling agent can be used for biochemical and environmental protection convenience. It is an important raw material for preparing silicone solid pancreatic enzyme carrier, which can improve the utilization rate of biological enzymes and avoid pollution and waste.
