Abstract

The invention belongs to the technical field of silicone rubber, and particularly relates to addition type liquid silicone rubber and a preparation method and application thereof. The invention provides the addition type liquid silicone rubber on the first aspect. The addition type liquid silicone rubber comprises a first mixture and a second mixture. A preparation method of the first mixture comprises the following steps: step 1, mixing raw materials, and carrying out heat treatment to obtain base rubber, wherein the raw materials comprise vinyl-terminated silicone oil, white carbon black, a treating agent and water; and step 2, mixing the base rubber, methyl-terminated ethylene silicone oil, vinyl-terminated silicone oil and a platinum catalyst to prepare a first mixture. A preparation method of the second mixture comprises the step of mixing the base rubber, methyl-terminated ethylene silicone oil, hydrogen-containing silicone oil, vinyl-terminated silicone oil and an inhibitor to prepare the second mixture. The invention provides the addition type liquid silicone rubber and the preparation method thereof, and can effectively solve the technical problems that bubbles are easily generated and oil is easily generated due to high viscosity of an existing silicone rubber material.

Description

technical field

[0001] The application belongs to the technical field of silicone rubber, and in particular relates to an addition-type liquid silicone rubber and its preparation method and application. Background technique

[0002] With the improvement of people's living standards, the requirements for the quality of life are also getting higher and higher. In consideration of safety and environmental protection, traditional adult products and humanoid products are made of PVC materials, and in recent years, they have been gradually replaced by silicone rubber materials. This is because the silicone rubber material has good biocompatibility with the human body and will not produce allergic reactions after contact with the human body.

[0003] At present, there are two molding methods for silicone rubber material products, one is casting molding, and the other is liquid injection molding. More common is casting molding, and casting molding products have higher requirements...
