Anticorrosive paint for die-cast aluminum heating radiator and preparation method of anticorrosive paint

Abstract

The invention relates to anticorrosive paint for a die-cast aluminum heating radiator. The anticorrosive paint is composed of the following components in parts by weight: 35-55 parts of Ca-Zn-Se borophosphate, 15-25 parts of ceramic microbeads, 8.5-10 parts of betulin acid, 5-8 parts of modified phenolphthalein, 3-5 parts of iridium-acetylacetonate, 1.5-3.5 parts of acrylic acid, 0.6-1.2 parts of a wetting dispersant, 2.4-2.8 parts of tribenzyl phenol polyoxyethylene ether, 0.3-0.6 part of a thickening agent and 0.65-1.5 parts of an antifoaming agent. The anticorrosive paint disclosed by the invention has the advantages that 1, the production process is simple and reasonable, the input equipment is less, and the production cost is low; 2, the coating surface treatment requirement is low, the adsorption effect is excellent, the adhesive force is high, and the coating does not flake or discolor; 3, leveling and heat radiation effects are excellent, the heat transfer speed is high, and the heat efficiency is high; 4, the anticorrosive paint is resistant to acid, base and salt corrosion and seawater corrosion and excellent in anticorrosive effect; 5, the wear resistance and impact resistance are high.

Description

technical field [0001] The invention relates to coatings, in particular to an anti-corrosion coating for die-casting aluminum heating radiators and a preparation method thereof. Background technique [0002] With the rapid growth of my country's national economy, the income of residents has increased year by year, and living standards and housing conditions have been further improved. Die-cast aluminum heating radiators are widely used in northern regions due to their large heat dissipation surface area, high thermal efficiency, and comfortable temperature. [0003] At present, the surface treatment of die-casting aluminum heating radiators mainly adopts polyester powder coatings. Although the technology is mature and the process is simple, it is suitable for mass production. , after a long service life, the surface of the coating is easy to gradually change color or the coating peels off. The second is that the coating is generally between 80 and 120um, and the coating is ...

AI Technical Summary

Problems solved by technology

[0003] At present, the surface treatment of die-casting aluminum heating radiators mainly adopts polyester powder coatings. Although the technology is mature and the process is simple, it is suitable for mass production. , the surface of the coating is easy to gradually change color or peel off after a long service life

The second is that the coating is generally between 80 and 120um, and the coating is thin, resulting in a higher surface temperature of the die-casting aluminum heating radiator

Third, due to the influence of leveling, the heat radiation is small, which affects the heat dissipation effect

[0004] For this reason, many units and individuals have carried out development and research, such as the ceramic coating disclosed in Chinese patent 201310206460.5 and its preparation method and heating furnace furnace tube. Good; as in Chinese patent 201410293141.7, a ceramic coating containing 3D pattern effects has better decorative properties; as disclosed in Chinese patent 03129981.4, the fins for heat exchangers containing ceramic coatings and using this have better heat resistance; Such as Chinese patent 88102627.8 discloses a kind of coating for forming superconducting ceramic coating film, etc., which cannot solve the above-mentioned problems existing in the current die-casting aluminum heating radiator.
