Abstract

In order to solve the problems that for the existing powder paint, the heat insulation and heat preservation effects are difficultly realized by the direct spray coating of common powder paint, and the like, the invention relates to conduction heat insulation powder paint and a preparation method thereof. After the single paint spray coating for film formation through curing, an efficient heat preservation and heat insulation layer can be formed; an efficient insulation barrier is provided between the metal material surface and external environment. The conduction heat insulation powder paintis prepared from 55.5 to 143 weight parts of bottom powder and 5.55 to 14.3 weight parts of core-shell micropheres, wherein the bottom powder is prepared from film forming substances, filling materials, sand vein auxiliary agents, pigments, degassing agents and other auxiliary agents. The conduction heat insulation powder paint is novel paint designed by aiming at the heat conduction principle; the paint is applicable to indoor environment with heat insulation requirements; on one hand, the process is simple; on the other hand, the effects of energy saving and environment protection are achieved; the cost in each item is reduced. Compared with the existing heat insulation and heat preservation technology, the preparation method has the advantages that the process is simplified; through once spray coating, the heat conductivity coefficient is reduced; the effects of heat insulation and heat preservation are achieved, so that the cost is reduced.

Description

technical field [0001] The invention relates to a conductive and heat-insulating powder coating and a preparation method thereof. Background technique [0002] There are three ways of heat transfer: heat convection, heat conduction, and heat radiation. Most of the traditional thermal insulation coatings are reflective thermal insulation coatings designed for the principle of radiation heat transfer. For some indoor applications that require thermal insulation coatings, the demand cannot be met. Powder coatings are widely used on the surface of metal materials, and metal materials have high thermal conductivity. In some application environments with high thermal insulation requirements, such as buildings and pipelines etc. It is difficult to achieve the effect of heat insulation by direct spraying of ordinary powder coatings, and more complicated processes are required, such as aluminum profiles linking two profiles through glue injection for heat preservation, and pipes for...
