Problems solved by technology

However, the dynamic mechanical properties of organic small molecules depend on their molecular weight and their own structure. Improper selection will cause small molecules to precipitate from the polymer, thereby affecting the mechanical properties of the material and making it impossible for practical application.

Abstract

The invention discloses a high damping phenyl silicone rubber, a preparation method and application thereof, and belongs to the technical field of rubber materials. The high damping phenyl silicone rubber of the present invention is made from the following raw materials by weight: 80-150 parts of phenyl silicone rubber, 10-50 parts of damping filler masterbatch; the damping filler masterbatch is prepared from the following components by weight Composition: 100-150 parts of polar rubber, 10-30 parts of TMPPD. The preparation method of the invention comprises the steps of kneading, forming and vulcanizing the damping filler masterbatch and the phenyl silicone rubber. The invention creatively utilizes TMPPD and polar rubber to be blended to form damping filler masterbatch, which is added to the phenyl silicone rubber matrix to improve the compatibility between the "damping imparting agent" and the matrix, and can significantly improve the mechanical strength while ensuring higher mechanical strength. Improve the damping performance of the material at room temperature.

Description

technical field [0001] The invention belongs to the technical field of rubber materials, and in particular relates to a high damping phenyl silicone rubber and a preparation method and application thereof. Background technique [0002] Damping vibration isolation technology based on viscoelastic damping materials is an effective way to control vibration, shock and noise, especially for broadband random vibration and shock problems of high-precision equipment. Phenyl silicone rubber has many excellent properties such as weather resistance, aging resistance, electrical insulation, and wide temperature range of silicone rubber. As a damping material, it has advantages that other general-purpose rubbers do not have. [0003] However, the damping performance of phenyl silicone rubber cannot meet the actual needs of use. In order to improve its damping performance, the method of introducing bulky side groups into its molecular side chains can be used in the current technology. Alt...
