Modified Silicone Resin Acrylic Resin -- 2023-06-07

Organic silicon is a synthetic material of organic polymers containing silicon elements in the main chain of molecules, because its structure contains high bond energy Si-0 bonds (bond energy up to 425kJ/mol), which are much greater than the bond energy of C-C (375kJ/mol) and C-0 (35lkJ/mol) in acrylic monomers, making organic silicon highly flexible, good high and low temperature resistance, stability, and antioxidant properties; Moreover, due to its low surface tension and large molecular volu ...

Preparation of Organosilicon Modified Phenolic Resin -- 2023-06-01

(4)The synthesis of phenolic resin modified with octamethyltetrasiloxane D4: Firstly, melt phenol at a temperature of 40-45 ° C and add NaOH aqueous solution. After reaction for 1 minute, add the first formaldehyde, which accounts for 80% of the total input. Then maintain the temperature between 80 and 85 ° C, and after reaction for 1 hour, add one dose of methanol at a rate of 20% of the feed amount. The reaction temperature for the second dose of formaldehyde should be controlled between 70 ...

Preparation of Organosilicon Modified Phenolic Enzymatic Resin -- 2023-05-30

Example of Preparation of Organosilicon Modified Phenolic Enzymatic Resin(1)The adhesive used for copper foil insulation board is suitable for bonding copper pins and phenolic resin laminates with silica fired modified phenolic resin. It can be prepared from soluble phenolic resin, silicone coupling agent, polyvinyl alcohol succinase, and organic solvents; For example, press 640g C6 into OH, 400g HCHO, and 4 4g Zn (OAc) 2, heated and refluxed, dehydrated for 6 hours. Then dilute with 12.2g MeOH ...

Silicone Modified Phenolic Resin -- 2023-05-29

Factors affecting the performance of silicone modified phenolic resintemperatureThe adhesion of the coating film reflects the performance of the coating and directly affects the protective performance of the coating film on the substrate. However, during the use of the coating, especially under high temperature conditions, it will be subjected to the synergistic effect of factors such as thermal stress and corrosive media, which reduces the bonding strength between the coating and the substrate ...

Synthesis of Organosilicon Modified Phenolic Resin -- 2023-05-26

There are two methods for synthesizing thermosetting organosilicon modified phenolic resin: one is to prepare thermosetting organosilicon modified phenolic resin by hydrolyzing oligomers with chlorosilane and phenolic resin. The resin prepared by this method is mainly used in the manufacturing of copper coated pins due to its low molecular halo, relatively poor toughness and heat resistance.Another preparation method for organosilicon modified phenolic resin is to first prepare linear phenolic r ...

Application of Organosilicon Modified Epoxy Resin -- 2023-05-25

The ratio of polysiloxane to epoxy resin determines the performance of the resin. The high content of epoxy resin results in strong adhesion of the product, but its heat resistance is affected. Polysiloxane products with high twist content have obvious characteristics of high heat resistance and good electrical properties, but the adhesion and formability of the resin need to decrease. Therefore, it is necessary to find the optimal ratio of siloxane to epoxy in silicone epoxy resin through the f ...

Application of Epoxy Silicone Resin -- 2023-05-24

Epoxy silicone resin has excellent heat resistance, oil resistance, dielectric resistance, and electrical properties. Epoxy silicone coatings can be cured at different temperatures using different curing agents. Diethylenetriamine and ethylenediamine can be used as curing agents to cure at 50 ° C. If polyamide is used as curing agent, a low-temperature dry and flexible paint film can be obtained; Baking type coatings can be obtained by curing with melamine or pulse resin.In order to achieve the ...

Application of Modified Epoxy Resin -- 2023-05-23

Phenolic epoxy ECN was modified with OMS and DPS respectively, with an OMS dosage of 5 At 7g, Tg reaches 161.83 ° C and Is reaches 14 OkJ/mV increased by 15% compared to unmodified ones At 43 ° C and 8kJ/m2, when modified with DPS of different qualities, the stone showed varying degrees of decrease. This is because ECN has a high polarity and poor compatibility with large molecules. At this time, only small molecules can achieve better modification effects.By reacting the end group chlorine wi ...

Reaction of Hydroxyl Terminated Polydimethylsiloxane with Epoxy Resin -- 2023-05-22

The copolymer can be cured at 14o ℃, 1h, 18 ° C, and 2h. The long carbon chain Cu at both ends of PDMS can increase its compatibility with bisphenol A, thereby increasing cohesion. Add 10% PDMS with a molecular weight of 3000 to disperse the soft chain segments into epoxy resin, and the minimum particle size can reach 0 23 µ m., toughness improved.Reaction between Vinyl Silicone and Vinyl Epoxy ResinAn epoxy resin containing vinyl in its molecular structure was prepared by the reaction of o-c ...

Preparation of Modified Epoxy Resin -- 2023-05-19

Experimental results have shown that the toughening modification of epoxy resin by polydimethylsiloxane has good results at low percentage content. With the increase of molecular weight and percentage content of epoxy resin, the mechanical properties of its copolymer have been improved within a certain molecular weight range.One of the key technologies for developing epoxy sealing materials for megabit level VLSI is the preparation of low stress modified epoxy resin. The main idea of modifying l ...
