Abstract

The invention discloses an ultra-light hot-melt damping panel. The ultra-light hot-melt damping panel comprises the following materials by weight percent: 30.1-34.4% of pitch, 4.5-5.6% of modifier, 3.3-6.9% of additives, 5.1-6.2% of mica powder, 30.4-41.2% of calcium carbonate and 15.8-23.4% of glass beads. The ultra-light hot-melt damping panel can solve the problem of high density of the hot-melt damping panel at present. A high-performance hollow glass bead is used for replacing local calcium carbonate, so that the purpose of reducing the density of the damping panel is achieved.

Description

technical field [0001] The invention relates to a damping plate, in particular to an ultra-light hot-melt damping plate. Background technique [0002] The damping plate is often used in the painting station of the automobile factory, and its function is to absorb shock and sound. Usually, the hot-melt damping plate is composed of base material asphalt, modifiers, additives, mica powder, calcium carbonate and other inorganic fillers. Generally, the density of mica powder is 2.7-3.5, and the density of calcium carbonate is 2.7-2.95. The proportion of these two components in the damping plate should account for about 60%, so the final density of the damping plate is also about 1.8-1.9. The amount of this hot-melt damping plate used in a car is 7-9kg. [0003] The disadvantage of this kind of damping plate is that it has a high density, which is not conducive to the development of lightweight automobiles. At the same time, the damping plate is laid manually, and the labor inte...
