Group 8 transition metals have attracted much attention because of their special catalytic properties. More than 100 years ago, the metal olefin complex first obtained by scholars was the compound of zero valent platinum and ethylene, that is, the famous Zeiss salt; Subsequently, sutures of other group 8 transition metals and various olefins were obtained, such as ferrocene. However, in terms of structure, the radius of platinum atom in the sixth cycle is relatively large and the number of electron layers is large. Its inner F layer is full of electronic structure, which makes its energy level and radius close to olefin double bond, so it is more suitable to produce catalytic effect in the field of silica gel. In terms of practical effect, scholars have studied other eighth group transition metals and proposed to use nickel Cobalt and rhodium are tried, but their reaction effect, initiation temperature and applicability are not as good as metal platinum, so platinum is widely used in organosilicon addition.

Platinum catalyst is a platinum catalyst with high activity and high catalytic efficiency, which can efficiently catalyze the addition reaction of Si VI and Si-H without side reactions. At the same time, the product also has the advantages of good stability and strong toxicity resistance, which can avoid the formation of black substances during the storage or use of the product and reduce the impact of nitrogen and sulfur-containing substances. In addition to the above advantages, it also has the advantages of good selectivity, no by-products, little impact on the transparency of the compound, high transparency products and environmental protection, and no toxic gas release in the vulcanization process.

Platinum catalyst applications:

1, it can be used as a catalyst for liquid addition silicone rubber, silicone gel, addition molding compound, electronic potting adhesive, silica gel ink and so on.

2. Catalysts for synthesis of polyether silicone oil and amino silicone oil.

3. Other occasions of hydrosilylation reaction.

4. Paper separator

5. Modified silicone

6. Flame retardant silicone products are efficient environmental flame retardants.
