Epoxy acrylate modified high anticorrosion heat insulation paint containing porous ceramic addictive and production method thereof

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of paint chemistry, and in particular relates to an anti-corrosion and thermal insulation paint composition and a preparation method thereof. Background technique [0002] The world's industry is increasingly developed, the population is increasing, and human beings are destroying nature, so that the temperature of the earth's surface is also increasing day by day, the earth's resources are becoming increasingly exhausted, and human life and survival are increasingly affected and threatened. Therefore, energy saving and consumption reduction The work has attracted the attention and attention of all countries in the world, and various energy-saving materials have become one of the basic goals of scientific research and technology development in the world. Energy-saving materials will also be more and more popular. [0003] Existing thermal insulation coatings generally use silicate materials such as asbestos,...

Problems solved by technology

However, the unit cost is high, there is no anti-corrosion performance, and it is not resistant to aging, so the scope of use is limited.

[0005] The Chinese patent with the publication number CN1583895A, although the heat insulation effect is achieved by adding hollow ceramic beads to reduce the thermal conductivity, but the coating uses xylene, which is harmful to the environment

[0006] The Chinese patent with the publication number CN1485381A uses a water-based heat-insulating coating of styrene-acrylic emulsion, which has neither elastic effect nor good weather resistance and aging resistance

[0007] Publication number is the Chinese patent of CN1271747A, and the exterior wall paint disclosed is based on pure acrylic emulsion, and titanium dioxide, light calcium carbonate, etc. are used as fillers. The aging resistance, heat resistance and heat insulation performance of such products are relatively poor
