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

Embodiment Construction

[0015] The heat-absorbing particle of the present invention is a microencapsulated microparticle with a core particle diameter of 1-1000 μm, the particle composition includes a shell and a core, and the shell is a compound selected from melamine formaldehyde, urea formaldehyde resin, PU, and acrylic high molecular polymer, the core is a heat-absorbing material selected from straight-chain alkanes, higher alcohols, and organic acids with a melting point of about 35°C-70°C, the weight of the shell and the core The ratio is about 1 / 20-1 / 2. In addition, dyes can be added to the core to become pigments with color and heat absorption, that is, the heat-absorbing particles in this article include or do not contain A general term for dyes, while heat-absorbing pigments refer to dyes.

[0016] figure 1 Shown is the preparation and spraying method of heat-absorbing particles of the present invention, which mainly uses heat-absorbing substances that are easy to store and emit heat, and ...

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. [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, bec...
