Acrylic damping adhesive and diaphragm membrane for micro-speakers |
| abstract |
The present invention provides an acrylic damping adhesive. The acrylic damping adhesive comprises a crosslinked structure of a carboxy-containing acrylic polymer with a glass transition temperature less than or equal to -20 °C °C and a carboxy-containing acrylic polymer with a glass transition temperature ranging from 20 °C to 50 °C. The acrylic damping adhesive according to technical solutions of the present invention exhibits double damping peaks in a rheological curve, and thus has a wider damping temperature range (the damping temperature range is greater than or equal to 50 °C, and preferably greater than or equal to 90 °C), a higher frequency response of damping, and higher system stability. |
