Abstract

The invention discloses a radiating material and a preparation method of the radiating material. The radiating material comprises a component A and a component B, wherein the component A is an ionic modified resin, or a mixture of more than one ionic modified resin, or a composite of more than one ionic modified resin; and the component B is one or more mixed material with the far infrared emission rate greater than 0.80 or thermal conduction coefficient greater than 5W / m.K, and grain size smaller than 30mu. In use, the radiating material can not only improve the radiating performance of metal parts, but also achieve certain other special functions (for example, self-cleaning, infrared stealth, thermal insulation, corrosion resistance, thermostability, self-lubricating, insulation and other properties), and can be prepared into most needed color according to requirement.

Description

technical field [0001] The invention relates to surface treatment technology, in particular to a heat dissipation material for improving the heat dissipation performance of metal components and a preparation method thereof. Background technique [0002] The heat dissipation performance of metal parts (especially radiators) has been paid more and more attention in today's society. At present, most of the surface treatment technologies for metal parts cannot improve the heat dissipation performance, and some even cause thermal resistance (such as: electroplating, anodic oxidation, vacuum plating); spraying liquid heat dissipation (cooling) paint or powder heat dissipation (cooling) paint, the appearance is not good , and there are dead ends, which are criticized by producers. [0003] Therefore, the prior art still needs to be improved and developed. Contents of the invention [0004] In view of the above-mentioned deficiencies in the prior art, the object of the present i...
