Microcapsulation heat absorbing particle

Abstract

A microcapsule-type heat absorbing particle able to be sprayed on the surface of object for absorbing a great deal of heat is a (1-1000)-micron particle which is composed of shell and core. Said shell is a high-molecular polymer chosen from melamine formaldehyde, urea-formaldehyde resin, PU, etc. Said core is a heat-absorbing substance chosen from straight-chain alkane, high-grade alcohol and organic acid.

Description

technical field [0001] The invention relates to a kind of microencapsulated heat-absorbing particles, which can be coated on the surface of metal or non-metallic components to provide heat-dissipating effect, and dyes can also be added to provide coating pigments in addition to providing heat-dissipating effect. Background technique [0002] "Pigment" broadly means a kind of colored particulate matter, which exists in the medium with stable physical and chemical properties, and is used as an additive raw material for coloring processing. Coloring processing additives in ink, textile, papermaking, leather, plastic, rubber, resin, glass and other processes, so the use of pigments adds a lot of color to our daily life.

Problems solved by technology

[0003] Paints and coatings are the most widely used in daily life. Most of them are used to increase the color of the surface of objects and to isolate air to prevent oxidation. However, this kind of use is not suitable for most heat dissipation components, because paints and coatings are coated on The surface of the heat dissipation component will reduce the heat conduction efficiency, so most of the heat dissipation components are exposed to the air with raw materials, so if the heat dissipation component is made of an easily oxidizable material (such as iron), it is prone to rust, while Corrosion also reduces the efficiency of heat dissipation and the life of the product

[0004] The current computer components, electronic product components or mechanical products, etc., will continue to generate unwanted heat during operation, so heat dissipation components such as fans, heat sinks, and heat pipes are usually installed on the components that generate heat in the equipment , in order to accelerate the dissipation of the heat generated by the equipment, but with the innovation and improvement of product performance, the heat generated by the above-mentioned equipment is also increasing day by day, and the temperature is even as high as 100 ° C. Therefore, if the heat dissipation efficiency is not developed Heat dissipation device, too high temperature is bound to cause adverse effects on the equipment
