Problems solved by technology

Because the loss peak shifts to the high temperature direction, the practical application of hybrid damping materials is limited to a certain extent. Therefore, it is necessary to further study the new vibration reduction mechanism and develop a hybrid vibration damping compound with controllable loss peak temperature. Material

Embodiment 1

[0024] The mass percentage of each component of the multi-component hybrid high-performance vibration-damping composite material adopts chlorinated polyethylene (CPE): (2-hydroxy-3-cyclohexyl-5-methyl)-benzene ring (ZKF): 2,2-methylene Bis-(4-ethyl-6-tert-butylphenol) (EBP)=60:35:5, its preparation steps are as follows:

[0025] 1> Raise the roller temperature of the double-roller mixer to 60-65°C and keep it basically stable;

[0026] 2> Add 60wt% CPE between the rollers, soften the CPE by the surface temperature of the rollers, and make the CPE powder in a semi-fluid state under the action of the shear force generated by the difference in the rotational speed of the rollers, At the same time, use a cutter to do artificial mixing and knead for 10 minutes;

[0027] 3> Add ZKF organic small molecules with a mass percentage of 35wt% between the rollers. Due to the difference in speed between the surfaces of the double rollers, the ZKF organic small molecules are dispersed in th...

Abstract

The invention relates to a method for preparing polyhydric hybridized high performance vibration- damping complex material. It comprises following steps: (1) mixing milling chlorinated polyethylene, (2- hydroxyl- 3- cyclohexyl- 5- methyl)- benzene ring and 2, 2- methylene bis- (4- ethyl- 6- tertiarybutyl phenol), cutting into particles for milling; (2) hot shaping, getting polyhydric hybridized high performance vibration- damping complex material; (3) testing peak value of loss factor tan delta and temperature position of loss peak value. The peak value of loss factor of complex material can be controlled, and can be used in automobile, railway transportation, construction, mechanics, househould apparatus and sports equipment. The operation is simple and suitable for industrial production.

Description

technical field [0001] The invention belongs to the field of preparation of engineering materials, and in particular relates to a preparation method of a multivariate hybrid high-performance vibration-damping composite material. Background technique [0002] The polymer damping material is based on the viscoelasticity of the polymer, that is, in the glass transition region, the internal friction generated by the molecular chain movement partially converts the mechanical energy or sound energy of the external field into heat energy dissipation, and has the function of vibration reduction. Functional materials for noise reduction are widely used in aerospace, transportation, mechanical equipment, construction, and daily life. Usually one of the evaluation criteria for damping materials is the level of the loss peak (tanδ) in the glass transition region. A single high polymer often needs to be modified because the damping loss peak is not high enough. [0003] In recent years...
