Description

Technical Field

[0001] The utility model relates to the technical field of heat-conducting structural adhesive production, in particular to a high-efficiency dispersing device for heat-conducting structural adhesive production. Background Art

[0002] Thermally conductive structural adhesive is a single-component, heat-conductive, room-temperature curing silicone adhesive sealant. Thermally conductive structural adhesive is cured by cross-linking through the condensation reaction of moisture in the air to release low molecules, and vulcanizes into a high-performance elastomer. It has excellent resistance to alternating hot and cold, aging resistance and electrical insulation properties, and has excellent moisture resistance, shock resistance, corona resistance, leakage resistance and chemical medium resistance.

[0003] During the production of existing thermally conductive structural adhesives, their raw materials need to be dispersed and stirred. During the dispersion of general thermally conductive structural adhesives, they need to be input into a dispersion device and stirred at high speed by a stirring component to disperse them. However, general dispersion devices mostly use stirring blades to perform unidirectional stirring during dispersion, and the thermally conductive structural adhesive cannot be fully dispersed, so it needs to be improved.
