Abstract

The invention discloses a light-reflection, heat-insulation and anticorrosion paint which is prepared by uniformly mixing components in percentage by weight as follows: 30%-35% of nano titanium dioxide coated hollow glass beads, 15%-20% of micron-size quartz sand, 44%-50% of fluorocarbon emulsion, 0.1%-1% of a rear earth assistant, 0.1%-1% of a dispersing agent, 0.1%-1% of a thickening agent, 0.1%-1% of a wetting agent, 0.1%-1% of a defoaming agent and 0.1%-1% of a film formation assistant. The light-reflection, heat-insulation and anticorrosion paint has the advantages of good weather resistance, corrosion resistance, thermal insulation, water resistance, stain resistance and abrasion resistance, efficient crack resistance and seepage prevention and the like. The problems about heat insulation and anticorrosion in the severe environments of high temperature and humidity, salt-spray corrosion, mould breeding and the like under the condition of tropical ocean monsoon climate are solved; and a building outer wall or a metal component surface is coated with the reflective heat-insulation and anticorrosion paint, so that the service life of the building outer wall or the metal component surface is prolonged, and the building outer wall or the metal component surface has the advantages of good weather resistance, corrosion resistance, thermal insulation, water resistance, stain resistance and abrasion resistance, efficient crack resistance and seepage prevention and the like.

Description

technical field [0001] The invention relates to a light-reflecting, heat-insulating and anti-corrosion paint suitable for climate conditions of tropical sea islands. Background technique [0002] Corrosion of metals in tropical marine areas has always been an important issue that plagues the construction industry and people's lives. At present, there are various related solutions, but the anti-corrosion purpose is mainly achieved through the coating method. Such as the use of inorganic zinc-rich coatings, organic-inorganic composite anti-corrosion coatings, thermal spraying and other methods, but most of these methods currently have various problems such as complex process, high cost, and poor effect. [0003] The fundamental problem of severe corrosion in tropical islands lies in the climate and environment of tropical islands which are different from other regions. High temperature, high salt spray, strong ultraviolet and other environments are important factors that cau...
