Oxidation reaction using unsaturated double bonds of peracetic acid and vinyl silicone resinCondensation reaction between bisphenol A type epoxy resin and low molecular weight polysiloxane containing Si -- OR and Si -- OHThe condensation reaction is carried out in three ways:1.The light group in polysiloxane reacts with the secondary tibial group in epoxy resin to generate a pressure of 0 and form a stable silicon oxygen bond:The epoxy group of epoxy resin is not affected between the shin group ...

Organosilicone epoxy resins with different chain lengths were synthesized using double Si-H terminated silica fume and vinyl epoxy resin as raw materials. The effects of the main chain length of silica fume on cationic polymerization and thermal discoloration, as well as the effect of catalyst concentration on thermal and UV discoloration were investigated.Polysiloxane has poor compatibility with epoxy resin and is not easy to blend, so direct copolymerization reaction is adopted for modificatio ...

As we all know, organosilicon has good chemical stability and hardly reacts with the active group of epoxy resin. The solubility parameter of 110 Shanghai silicone rubber o=7 8-1, solubility parameter of PDMS o=7 4~8, the solubility parameter of epoxy resin is about 10 9。 The solubility parameters of the two differ greatly, and according to the principle of similar solubility parameters, the compatibility between silicone and epoxy resin is poor. If the two are simply mixed together during modi ...

Adding block copolymers based on silica fired epoxy to the blend of organic silicon and epoxy resin is due to its unique structure. This block copolymer can promote the penetration between resins and improve compatibility. Adding a block copolymer of silica fired epoxy group to a blend of bisphenol A epoxy resin and room temperature vulcanized polysiloxane (RTV) resulted in a decrease in interfacial tension between the epoxy resin and the silicone resin due to the presence of the block copolymer ...

Due to the significant difference in solubility parameters between organic silicon and epoxy resin, the compatibility between organic silicon and epoxy resin is poor based on the principle of similar solubility parameters. If the two are simply mixed together during modification, the modification effect is not good enough due to the high interfacial tension between the two phases and the multiphase separation structure. In order to improve compatibility, it is necessary to modify organic siloxan ...

Epoxy resin refers to a polymer oligomer containing two or more epoxy groups, with organic compounds such as fats, alicyclic or aromatic groups as the backbone, and can form useful thermosetting products through the reaction of epoxy groups.Any polymer with an epoxy based silicone structure can be referred to as an silicone epoxy resin.Epoxy resin is an excellent thermosetting synthetic resin material, which has excellent adhesion, high mechanical strength, good chemical stability, low coefficie ...

The organic silicon intermediates used in this preparation process are generally some low molecular weight compounds of the organosilicon class. Due to the tendency of low molecular weight silicon with tibia groups to self aggregate at high temperatures, low molecular weight silicon with tibia groups are often selected, such as methyltrimethoxysilicon,methyltriethoxysilicon,dimethyldimethoxysilicon,dimethyldiethoxysilicon,ethyltrimethoxysilicon, ethyltrimethoxysilicon, and propyltrimethoxysilico ...

In polyester modified silicone resin coatings, the introduction of NC2 pressure ratio NHC3 pressure Si COMe and SiCOCH pressure ratio OMe can achieve low-temperature curing. For example, 100 parts by mass of polyester [40 0: 70. Copolymer prepared from 4 parts of dimethyl terephthalate and trilight methyl propanol, 150 parts of methyl phenyl silicone resin intermediate, 167 parts of cellulose acetate, and 0 Three parts of isopropyl methacrylate were reacted at 150 ° C for 4 hours, and then di ...
