Abstract

The invention relates to a multimode organic filter / polymer composite damping material and a manufacturing method thereof, relates to the field of soundproof materials, aims to solve the problems that in the prior art high efficient soundproof materials do not have a prominent effect, and generate harmful gas, which harms the human health; and provides a multimode inorganic filler / polymer composite damping material. The damping material comprises the following materials: thermoplastic resin and an inorganic filler, which has been subjected to a surface treatment with a coupling agent processing fluid; wherein the inorganic filter accounts for 15 to 80 wt% of the total weight of the damping material, and the balance being thermoplastic resin. In the damping material, the binding between each particle is abnormal, thus the internal friction between incident sound waves in this structure is effectively increased, thus a relaxation effect is generated, and the sound is absorbed. Fillers with different particle sizes are corresponding to sound waves in different bandwidths or frequencies, so sounds in different frequencies can all be absorbed by the damping material, and moreover the damping material has a good soundproof effect, and is suitable for promotion and application.

Description

technical field [0001] The invention relates to a novel high-efficiency damping material and a manufacturing method thereof. It belongs to the field of sound insulation equipment; the material is based on a compound of a large amount of inorganic multimodal filler and polymer resin, and then calendered into various shapes (conventional such as plates). The invention relates to a high-filling polymer tree with a glass transition temperature (Tg) near room temperature (-30-80°C) and its composite matrix (such as acrylic glue, polyurethane and other polymer glue), which can be controlled by controlling the proportion of components It is easier to control the viscoelasticity of the microstructure, effectively improving the loss effect on vibration; and the particle distribution of the multimodal filler can be designed, so that the absorption peak of the composite material is in a "controllable state". The material is lower in cost than the nano-filled material, safe, environmenta...
