Abstract

The invention relates to a method for manufacturing a building board which has corrosion resistance and weather resistance, can prevent dew from dripping and has certain thermal insulation performance, in particular to a method for manufacturing a flocked hot-dip galvanized printed board. The method includes the following steps: material selection, board surface pretreatment, drying treatment, printing, spreading of an adhesive and epoxy zinc-rich paint mixture, electrostatic flocking, drying, checking and warehousing; the method is characterized in that dacron flock is adopted in the electrostatic flocking step, and the GR934 passivator is adopted as a board surface treating agent. The board obtained through the method has excellent fire resistance; as is shown in detection, the board passes the National Building Material Fireproofing Grade B-1 Certification and is environmentally friendly and free of pollution; the board also passes the Environmental Certification, can be directly used indoors and has the advantages of being strong in upright-flock sense, bright in color, capable of achieving comfortable touch and good in sound absorption performance, light absorption performance and light diffuse reflection effect.

Description

technical field [0001] The invention relates to a method for manufacturing a building plate with corrosion resistance, weather resistance, dew condensation prevention, and thermal insulation performance, especially a method for manufacturing a flocking hot-dip galvanized printing plate. Background technique [0002] In modern decoration, hot-dip galvanized sheets are used in many cases, such as square hot-dip galvanized gussets for integrated ceilings, and large-area hot-dip galvanized paint panels for wall decoration. The flocking hot-dip galvanized sheet can provide more luxurious decorative effects than existing products. The fleece itself has a certain water absorption capacity. When the ambient humidity is too high, it can keep the condensation water on the surface of the sheet to prevent water droplets from dripping . However, the flocking hot-dip galvanized sheet has a weak velvet feel and monotonous color, especially as the surface area of ​​the flocking surface exp...
