studies on the damping properties of polyacrylate emulsion/hindered phenol hybrids  -  polyacrylate
Organic hybridization of polyacrylic emulsion (PAE)
Blocked phenol (3,5-bis(1,1-dimethylethyl)-4-
Thio-phenic acid-2,1-
Acetate, abbreviated as Irganox-1035)
Ready for this study.
Dynamic mechanical properties expressed by energy storage modulus (E′)
And loss factor (tanδ)
This binary system is studied.
Dynamic Mechanical Analysis (DMA)
The results show that by adding Irganox-
At 1035, the peak value of tan delta in the hybrid combination was 4.
2, show the PAE/Irganox-
The 1035 hybrid is a promising damping material.
The damping mechanism of hybrid vehicles is also systematically studied by Fourier transform infrared spectroscopy (FTIR)
Differential Scanning Heat Meter (DSC), X-
Ray diffraction (XRD)
DMA and scanning electron microscopy (SEM).
The experimental results show that there is no hydrogen bond between the acrylic resin matrix and Irganox-
1035 molecules and PAE and Irganox-
1035 is present in the hybrid in amorphous form.
At the same time, the DMA results show that,
1035 has a super
High viscosity elasticity (tanδ=20. 7)
The damping performance of the compatible hybrid power system is improved.
