Anti-corrosion heat insulation coating and preparation method thereof

Abstract

The invention discloses an anticorrosion heat-insulation paint and a preparation method thereof. The paint comprises a base material and a solvent. The base material comprises an expoxy heat-insulation paint, auxiliary pigment and filling materials, a heat-insulation filling material, an antifoaming agent and a dispersant. The expoxy heat-insulation paint is composed of the following components in parts by weight: 40.21 to 40.61 parts of epoxy resin (the membrane), 40.21 to 40.61 parts of polyamide resin (curing agent), 3.76 to 4.16 parts of titanium dioxide, 3.76 to 4.16 parts of talcum powder, 7.52 to 8.52 parts of xonotlite-type calcium silicate (heat-insulation filling material), 1.61 to 1.63 parts of polyoxypropylene glycerol ether (antifoaming agent), 1.61 to 1.63 parts of polyacrylamide (dispersant), 11.86 to 15.1 parts of n-butanol, and 26.05 to 29.49 parts of xylene. After curing, the paint forms an enclosed micro-porous and netted fiber structure on the substrate, has the characteristics of good anticorrosion performance, strong adhesive force, and high compressive strength, and thus solves the problems of bad impact-resistant performance and low adhesive force on wall of conventional barrier heat-insulation paints. Moreover, the paint is convenient for construction, can be painted or brushed, and has strong plasticity.

Description

technical field [0001] The invention relates to a paint, in particular to an anti-corrosion heat-insulation paint and a preparation method thereof. Background technique [0002] At present, thermal insulation coatings are widely used in various fields of the national economy. However, general thermal insulation coatings are poor in reducing convection and radiation heat transfer, and the thermal insulation layer is thick, not resistant to vibration, high water absorption, and long service life. Short, poor anti-corrosion ability, the most widely used barrier type thermal insulation coating is composite silicate thermal insulation coating, which has been widely used in practical applications. However, the coating still has defects caused by its own material structure, such as long drying period, construction conditions are greatly affected by seasons and climates, poor impact resistance, large drying shrinkage, high moisture absorption rate, and low bond strength to the wall ...
