Example Embodiment

[0026] Example 1:

[0027] Material mass ratio: silicone rubber 100; fumed silica 20; hexamethyldisilazane 2; diphenylsilanediol 1; 2,5-dimethyl-2,5-bis(tert-butyl base peroxy) hexane 1; methacryloxypropyltrimethoxysilane 1; mica powder 3; vermiculite powder 1; molybdenum disulfide 0.1.

[0028] The material preparation method of embodiment 1:

[0029] Firstly, each material component is weighed in proportion, and the mass error of each material component is controlled within 5%. First, put each material component into the internal mixer for internal mixing, and the temperature is controlled below 100°C. After the mixing is completed, the mixed rubber is mixed again on the open mill, and then the tablets are taken out and left to cool for 24 hours. Put the kneader on the open kneader and add 2,5-dimethyl-2,5-bis(tert-butylperoxy)hexane for kneading. After the kneading is completed, the tablets are released and left to cool for 24 hours. Use the material to prepare standard...

Abstract

The invention relates to the technical field of high polymer materials, in particular to a damping silicon material and a preparation method thereof. The damping silicon material comprises the following raw materials in parts by mass: 100 parts of silicone rubber, 20 to 100 parts of fumed silica, 2 to 4 parts of hexamethyl-disilazane, 1 to 5 parts of diphenyl silanediol, 1 to 2 parts of 2, 5-dimethyl-2, 5-di (tert-butylperoxy) hexane, 1 to 3 parts of methacryloxy propyl trimethoxyl silane, 3 to 10 parts of mica powder, 1 to 5 parts of vermiculite powder, and 0.1 to 1 part of molybdenum disulfide. The damping silicon material takes silicone rubber as a base material of a damping material, and can be normally operated at 50 to 150 DEG C; in addition, crystallization and vitrification of thematerial do not occur, and structural damage cannot occur; furthermore, the damping capacity of the silicon rubber material is greatly enhanced through the adding of the molybdenum disulfide to adjustthe damping capacity of the silicone rubber material, so that the material can be normally applied to the field of vibration insulation and noise reduction, and the vibration isolation performance ofa silicon material vibration isolator is enhanced.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a high-performance damping silicon material and a preparation method thereof. Background technique [0002] Damping rubber material is a kind of energy dissipation material, which is usually used to control engineering vibration and noise problems. Reasonable use of damping rubber materials can improve the vibration resistance and stability of various mechanical products and engineering structures, prolong the working life, improve the quality of products, and effectively reduce noise and vibration to prevent environmental pollution. [0003] The existing damping rubber materials are usually based on butyl rubber or nitrile rubber, supplemented with styrene-butadiene rubber, neoprene, etc., and some damping additives are added on this basis to prepare damping rubber for engineering applications. Material. [0004] However, due to the influence of the characteristic fa...
