Problems solved by technology

[0003] In the marine environment, the atmosphere is rainy, high temperature, strong wind and high concentration of salt spray. The flocked hot-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, the flocking hot-rolled steel plate has a weak velvet feel and monotonous color, especially with the expansion of the surface area of ​​the suede surface, the flocked hot-rolled steel plate cannot achieve excellent light diffusion. reflection effect

Abstract

The invention relates to a manufacture method of a flocking board which has corrosion resistance, weather fastness and certain thermal insulation property and prevents dew from dripping, in particular to a manufacture method of a flocking hot rolling anticorrosion spraying decoration and knurling board used for the oceanographic engineering. The manufacture method comprises the following steps: material selecting, preservative liquid dip-coating, anticorrosive coating spraying, smearing and scraping, baking curing process, adhesive coating, electrostatic flocking, flocking suction, drying procedure, brushing, spraying decoration, knurling and inspection and storage. With adoption of the manufacture method, the obtained product is excellent in corrosion resistance, wear resistance, erosion resistance and hydrothermal resistance, is stable in performance after being used in the marine environment with high salt mist concentration for a long time, long in service life, high in sense of upright pile, dazzlingly beautiful in color and soft in touch sense, has the functions of noise reduction, sound absorption, light absorption and thermal insulation, passes the B-1 level authentication of the fire rating of national building materials of China, and also passes authentication of environmental protection.

Description

technical field [0001] The invention relates to a method for manufacturing a flocking plate with corrosion resistance, weather resistance, dew condensation prevention, and thermal insulation performance, especially a flocking hot-rolled anti-corrosion spray embossed plate for marine engineering. Background technique [0002] The production process of the flocking hot-rolled steel plate is the production process of coating a layer of flocking glue on the surface of the hot-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 hot-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 and heat preservation, strong sealing and convenient use. Simple and practical and beautiful. In m...
