How to prepare modified silicone resin? Silicone resin is an excellent material, and the modified silicone resin obtained by changing silicone resin has enhanced its function and expanded its application on the basis of silicone resin. Modified silicone resin needs to be prepared by corresponding methods. Today, let's take a look at how to prepare modified silicone resin.
Modified silicone resin can be prepared by a variety of methods. Here are some common methods:
1. Copolymerization method: copolymerize silane coupling agent with silicone monomer to prepare modified silicone resin. This method can be achieved through free radical polymerization, ion polymerization or condensation polymerization.
2. Grafting method: graft silicone resin with unsaturated organic monomer to prepare
modified silicone resin. This method can be achieved through free radical polymerization, ion polymerization or condensation polymerization.
3. Cross-linking method: cross-link silane coupling agent with silicone resin to prepare modified silicone resin. This method can be achieved through cross-linking reaction between silane coupling agent and functional groups such as hydroxyl and amino groups in silicone resin molecules.
4. Coating method: The silicone resin is wrapped on the surface of inorganic materials or other organic materials to prepare modified silicone resin. This method can be achieved by dissolving the silicone resin in an organic solvent, then adding the inorganic material or other organic material to it, and then coating it through stirring, drying and other processes.
The properties and application fields of modified silicone resins obtained by different preparation methods will be different, and can be selected according to actual needs.
