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 a manufacturing method of flocking plates which resist to corrosion and weather, prevent dew from dripping and have a certain heat-preserving property, in particular to a manufacturing method of a flocking cold-rolled antiseptic spraying and knurling plate for ocean engineering. The manufacturing method comprises the following steps of material selecting, preservative liquid dip coating, anticorrosive coating spraying, smearing, scraping, baking and curing treatment, adhesive coating, electrostatic flocking, flock absorbing, baking, brushing, spraying, knurling, inspection and storage. The product obtained through the method has excellent corrosion resistant performance, good wear resistant performance, excellent washout resistant performance and good humidity resistance performance, is stable in performance after being used for a long term in an ocean environment with high salt fog concentration, long in service life, strong in upright pile sense, glow in color and soft in touch sense, reduces noise, absorbs sounds and light, preserves heat, and passes through national building material fireproof grade B-1 certification and environment-friendly 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 spray embossed plate for marine 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 ...
