Problems solved by technology

In general, the heat resistance can be improved by adding metal oxides, but there are three problems with the use of metal oxides: one is that a large amount of addition is required to improve the heat resistance; the other is that metal compounds and silicon The compatibility of rubber is not good, and phase separation is prone to occur; the third is that the addition of a large amount of metal oxides will affect the transparency and modulus of silicone rubber, which limits the application field of silicone rubber
The silicone rubber heat-resistant additive has good compatibility with silicone rubber, and can also increase the maximum service temperature of silicone rubber. However, the heat-resistant additive has a complicated formula and high production cost, which is not conducive to popularization and application.

Abstract

The invention belongs to the technical field of organic metal complex, in particular to a soluble organic metal complex and a preparing method and application thereof. The soluble organic metal complex has a structural formula shown in the description, wherein R1 is carboxyl, ester group, aminopropyl, propyl methyl phosphate, phosphate and boric acid ester; R is (CH2)8COOCH2; x is 1-10, n is 1-10 and M is ferrum, copper, zirconium or aluminum. The soluble organic metal complex is good in compatibility with silicone rubber and low in additive amount without affecting transparency of the silicone rubber, and can improve the high temperature resistance of the silicone rubber. The soluble organic metal complex is simple in preparing method, low in preparing cost, high in yield and high in product purity.

Description

technical field [0001] The invention belongs to the technical field of organometallic complexes, and in particular relates to a soluble organosilicon metal complex, a preparation method thereof and an application thereof in silicone rubber. Background technique [0002] The heat-resistant temperature of silicone rubber in the air is generally around 250°C, and when it exceeds 250°C, the silicone rubber will quickly become brittle and crack. In general, the heat resistance can be improved by adding metal oxides, but there are three problems with the use of metal oxides: one is that a large amount of addition is required to improve the heat resistance; the other is that metal compounds and silicon The compatibility of rubber is not good, and phase separation is prone to occur; third, the addition of a large amount of metal oxides will affect the transparency and modulus of silicone rubber, which limits the application field of silicone rubber. [0003] Therefore, there is an ...
