Preparation process (taking water-based silane coupling agent as an example)

1. dissolutionAdd a certain amount of aminosilane into deionized water and stir until the aminosilane is completely dissolved.

2. blendAdd nano silica into the solution while stirring.

3. reactionContinue stirring and heat to 80 ℃, maintaining the reaction temperature for 30 minutes.

4. separateTurn off the heater, wait for the reaction solution to cool down to room temperature, and use a filter to separate the precipitate.

5. Preparation completedMix the separated precipitate with a certain amount of deionized water to obtain an aqueous silane coupling agent.

Security

• Although water-based silane itself is not flammable in terms of chemical composition, under specific conditions such as hydrogen gas generated during processing and hydrogen peroxide produced by reacting with oxygen in the air, it may cause explosions. Therefore, when using water-based silane, it is necessary to comply with corresponding safety regulations, operate under ventilated conditions, and avoid mixing with oxidants and acidic substances.

conclusion

Water based silane, as an organic silicon compound with excellent properties, has broad application prospects in fields such as coatings, inks, adhesives, etc. Its good water solubility and flexibility enable it to significantly improve the performance of the product, while its preparation process is relatively simple. However, attention should still be paid to its safety issues during use to ensure the safety and reliability of the operation process.
