Embodiment Construction

[0024] The present invention will be further described in detail below in conjunction with specific examples.

[0025] As shown in Table-2, the ratio of raw materials for two kinds of heat-insulating and anti-corrosion coil coatings:

[0026] Table-2 Raw material ratio of two kinds of thermal insulation and anticorrosion coil coatings

[0027]

[0028] The base material resin mentioned in the table is the saturated polyester of model XD8560 specially used for coil coatings; the amino cross-linking resin is melamine urea-formaldehyde resin with end-blocking group and high etherification degree and model SN8000.

[0029] The thermal insulation filler described in the table includes two types of materials, one is the hollow microsphere material, the other is the thermal insulation nano-oxide, and the hollow microsphere material is TM-518 vacuum glass microsphere or TM-519 hollow ceramic Microbeads or TM-520 fly ash bleached enamel hollow microspheres, accounting for 80% of th...

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, which belongs 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 absorbs heat, releases heat, and c...
