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 present invention relates to a manufacturing method of a flocking plate with characteristics of corrosion resistance, weather resistance, dew-condensed water dropping preventing, and a certain thermal-insulation property, especially a manufacturing method of a flocking hot-rolling coating pattern-blowing plate for marine engineering. The manufacturing method comprises: material selecting, plate surface pre-treatment, drying treatment, cooling treatment, protection layer coating, coated protection layer drying treatment, coated protection layer cooling treatment, pattern blowing, slurry drying treatment, slurry cooling treatment, adhesive coating, electrostatic flocking, drying procedure, brushing, floss finishing, and inspection warehousing. The product produced by the method of the present invention has characteristics of strong upright pile effect, bright color, soft touch feeling, corrosion resistance, erosion resistance, good heat-resistant property, noise reducing, sound absorbing, light absorption, thermal insulation, excellent light diffuse reflection effect, complete environmental protection, and no pollution, and is tested by the national building material fireproof grade B-1 and the 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 certain thermal insulation performance, in particular a method for manufacturing a flocking hot-rolled coated blown plate used in ocean 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 practi...
