Abstract

The invention discloses antisticking tackifying damping glue and a preparation method of the glue, and relates to the production field of damping materials. The antisticking tackifying damping glue is mainly formed by mixing the following raw materials: 30-40 parts by weight of asphalt, 5-12 parts by weight of softener, 15-25 parts by weight of inorganic filler and 32-40 parts by weight of tackifying resin. The antisticking tackifying damping glue has an antisticking effect before heating and fusion, and better viscosity after the heating, and can be well fit with other objects.

Description

technical field [0001] The invention relates to the field of damping material production, and in particular to an anti-adhesive and thickening damping glue and a preparation method thereof. Background technique [0002] Damping materials are materials that can convert mechanical vibration energy into thermal energy and dissipate it. Mainly used to control vibration and noise. The damping properties of a material are measured in terms of its ability to dissipate vibrational energy. When the car is running, the vibration of the car will generate a lot of noise. At present, the damping film for the car is mainly used to control the noise. However, the existing damping films usually have the defects of being easy to stick after forming and not having enough stickiness during use. Contents of the invention [0003] The object of the present invention is to provide an anti-adhesive and thickening damping adhesive, which has anti-adhesive effect before heating and melting, and...
