Abstract

The invention provides a single-component addition-type silicone rubber which is prepared by vulcanizing the following raw materials in parts by mass: 20-50 parts of vinyl polysiloxane, 3-18 parts of vinyl methyl phenyl polysiloxane, 4-20 parts of hydrogen-containing polysiloxane, 0.01-0.1 part of platinum catalyst, 0.3-2.5 parts of inhibitor, 40-60 parts of filler, 2.0-10 parts of additive and 0.5-3 parts of tackifier. The single-component addition-type silicone rubber comprises the heat-resistant additive and the filler, so that the single-component addition-type silicone rubber prepared by vulcanizing has good high temperature resistance and low temperature aging resistance. The single-component addition-type silicone rubber comprises the catalytic inhibitor, so that the single-component addition-type silicone rubber has a higher inhibitory effect, and the storage life of the single-component addition-type silicone rubber is prolonged. When the addition-type silicone rubber is vulcanized, small molecular substances are not produced, and packaging components are not corroded.

Description

technical field

[0001] The invention relates to the technical field of addition-type silicone rubber, in particular to a one-component addition-type silicone rubber and a preparation method thereof. Background technique

[0002] Silicone rubber is a polymer elastomer whose main molecular chain is composed of silicon and oxygen atoms alternately, and there are usually two organic groups attached to the silicon atom. According to the applicable temperature, it can be divided into high temperature silicone rubber (HTV) and room temperature vulcanization (RTV); according to the vulcanization mechanism and use process, it can be divided into polycondensation reaction type and addition reaction type; according to different components, it can be divided into one-component silicone rubber. and two-component silicone rubber.

[0003] The one-component silicone rubber material is composed of a single component. Compared with the two-component silicone rubber, it does not need mixing ...
