The invention relates to a kind of heat insulation paint with a high anticorrosion performance and a preparation method thereof. The anticorrosion heat insulation paint is composed of following components in percentage by weight: 35 to 60% of deionized water, 20 to 40% of modified
epoxy resin, 5 to 30% of modified
acrylic resin, 1 to 8% of amino resin, 10 to 25% of heat insulation materials, 0 to 8% of strengthening materials, and 1 to 10% of auxiliary agent. The preparation method comprises following steps: orderly adding deionized water, modified
epoxy resin, modified
acrylic resin, and amino resin into a reactor, starting the stirrer, evenly mixing the materials, adjusting the pH value of the
system to a range of 7 to 9, then orderly adding the auxiliary agent, the heat insulation materials, and the strengthening materials, stirring for 1 to 3 hours in a high speed, and evenly mixing so as to obtain the anticorrosion heat insulation paint. The preparation method has the advantages of simple technology, high production efficiency, and low
energy consumption. The prepared paint does not contain any
organic solvent, so no
solvent will volatilize during the
coating solidification process, so no
pollution is generated to the environment. The paint has the advantages of excellent mechanical properties of
bonding strength,
hardness, scratch resistance,
wear resistance, and
water resistance, and good properties of anticorrosion, salt smog resistance, forming ability,
heat resistance, and deflection resistance.
