Problems solved by technology

[0003] In the marine environment, the atmosphere is rainy, high temperature, strong wind flow and high concentration of salt spray. The flocked cold-rolled steel plate has a certain decorative function, but it cannot adapt to the harsh marine climate in terms of corrosion resistance, erosion resistance, and heat and humidity resistance. environment, low service life, and high maintenance costs; moreover, flocked cold-rolled steel sheets have weak velvet feeling and monotonous colors, especially as the surface area of ​​the flocked surface expands, flocked cold-rolled steel sheets cannot achieve excellent light diffusion. reflection effect

Abstract

The invention relates to an anticorrosion, weather-proof, dew droplet-prevention and thermal insulation flocked plate manufacturing method and especially relates to a manufacturing method of a flocked cold-rolled anticorrosion embossed plate for sea engineering. The manufacturing method comprises material selection, plate surface pre-treatment, drying treatment, cooling treatment, Al-Zn-Si-Mg-Cu-RE-X(Ti, Ni and Mn) alloy powder gas atomization preparation, anticorrosive paint liquid preparation, anticorrosive layer spray-coating, anticorrosive coating drying, anticorrosive coating cooling, glue coating, static flocking, drying, brushing, embossing, and inspection and warehousing. The product obtained by the manufacturing method has the advantages of strong upright pile feeling, bright colors, soft feel, excellent corrosion resistance, good wear resistance, good erosion resistance, resistance to heat and humidity, long service life, noise reduction, sound absorption, light absorption and thermal insulation, passes the national building material fireproof grade B-1 level certification and passes the environmental protection certification.

Description

technical field [0001] The invention relates to a method for manufacturing a flocking plate with corrosion resistance, weather resistance, dew condensation prevention, and certain thermal insulation performance, especially a flocking cold-rolled anti-corrosion embossed plate used for ocean engineering. Background technique [0002] The production process of flocking cold-rolled steel plate is the production process of coating a layer of flocking glue on the surface of cold-rolled steel plate and then planting fluff with a length of about 0.4mm to 0.8mm. Because the fluff has the characteristics of vibration reduction, heat preservation, sound insulation, moisture absorption and beautiful decoration, the flocked cold-rolled steel plate not only has the characteristics of high strength, durability and can be recycled many times, but also has the characteristics of sound insulation, heat preservation, strong sealing and convenient use. Simple and practical and beautiful. In mo...
