Second, the classification of silicone resin.
1.Classified according to function:
Silicone removal resins can be divided into acid silicone removal resins and alkaline silicone removal resins according to their functions. Acidic silicone removal resins are mainly used to remove silicon elements from solution, while alkaline silicone removal resins are mainly used to remove silicon elements from gases.
2.According to the classification of synthetic raw materials:
According to the different synthetic raw materials, silicone removal resin can be divided into organic silicone removal resin and inorganic silicone removal resin. Organic silicone removal resin is synthesized from organic monomer, which has good flexibility and processabilityThe inorganic silicone removal resin is synthesized from inorganic substances and has high thermal and chemical stability.

Fourth, the preparation method of silicone resin.
1.Polymerization Reaction Method:
Monomers with active groups in the polymer chain are synthesized by polymerization, and then a catalyst is added for polycondensation reaction to generate silicone removal resin. The polymerization reaction method has the advantages of simple process and low cost, but the molecular weight distribution of the obtained resin is wide.
2.Radiation grafting:
High-energy radiation is used to induce polymer chain breakage, and then the required functional groups are grafted on the broken polymer chain to generate silicone removal resin. The radiation grafting method has the advantages of simple process and fast reaction speed, but the molecular weight distribution of the obtained resin is also wide.
3.Solution Polymerization:
The monomer with the active group is dissolved in an organic solvent, and then a catalyst is added for polymerization to produce silicone removal resin. The solution polymerization method has the advantages of simple process and high product purity, but the molecular weight distribution of the obtained resin is narrow.
