Ultrathin metal plate heat-insulation reflection coating and its preparation method

Abstract

The invention relates to an ultrathin metal plate heat-insulation reflection coating and its preparation method. The coating comprises a priming paint and a finish. The preparation method which adopts two coats comprises the following steps: coating the priming paint on a metal plate, and then coating the finish. The priming paint comprises the following components, by weight, 40-60 parts of a film forming resin, 20-30 parts of a pigment, 0-10 parts of a filler, 2-5 parts of auxiliary agents, 5-20 parts of a solvent, and 5-15 parts of a curing agent; and the finish comprises the following components, by weight, 40-60 parts of the film forming resin, 20-30 parts of the pigment, 2-10 parts of the filler, 2-5 parts of the auxiliary agents, 5-20 parts of the solvent, and 5-15 parts of the curing agent. Compared with coatings prepared through the prior art, the coating provided by the invention has the advantages of thin coat thickness, wide application range, convenient construction and the like.

Description

technical field [0001] The invention relates to a paint, in particular to an ultra-thin metal plate heat-insulating reflective paint and a preparation method thereof. Background technique [0002] In order to cool down, people have used many methods, and thermal insulation coating is one of them. Thermal insulation coatings mainly include reflective, radiative, barrier, phase change and hybrid types. Reflective heat-insulating coatings reflect the energy of solar energy by highly reflective substances. Radiative heat-insulating coatings emit absorbed solar energy to the outer space in the form of long waves. Barrier-type reflective coatings mainly rely on preventing heat convection from making heat Can't reach inside, the phase-change heat-insulating coating is to absorb energy through the phase-change material in the paint at high temperature and undergo a phase change to store the energy, and then release it when the temperature is low. There are two types of hybrid heat-...

AI Technical Summary

Problems solved by technology

At present, there are many kinds of thermal insulation coatings on the market, most of which are relatively thermal insulating pigments and fillers such as resin and glass microspheres or ceramic microspheres. However, due to the particularity of the fineness of thermal insulation materials, good decoration cannot be achieved after coating. effect, and to achieve a high heat insulation effect, the thickness of the coating generally reaches 200 microns to 500 microns. These effects and requirements greatly restrict the application range of heat insulation coatings, and pre-coating and large-scale factory production cannot be achieved.
