Abstract

A paint for the coiled insulating and anticorrosion material is prepared from special polyester resin, high etherified cross-linking resin and pigment, functional insulating filler, special chemical assistant and solvent through proportional mixing, dispersing, grinding, adding insulating filler, etc. Its advantages are no poison and pollution, high flame-retarding and insulating effect, and high resistance to ageing and corrosion.

Description

technical field [0001] The invention relates to a heat-insulating and anti-corrosion coil coating and a manufacturing method thereof, belonging to the technical field of chemical compositions. Background technique [0002] At present, the galvanized steel sheet coils and colored steel sheet coils on the market do not have the function of heat insulation. If galvanized tiles and color steel tiles pressed by such steel plates are used for roof covering, the indoor temperature will rise to 40-50°C in hot summer, which is scorching hot and unbearably hot. In order to solve this problem, in recent years, someone has developed a heat-insulating coating for building roofs (cement surfaces, colored tile surfaces) and exterior walls. However, these coatings all belong to the self-drying repair paint category, and are not suitable for the coating process of cold-rolled strips operated by automated production lines. [0003] The color steel plate coated with ordinary coil coating abs...
