Problems solved by technology

[0003] In the marine environment, the atmosphere is rainy, high temperature, strong wind and high concentration of salt spray. Flocking hot-dip galvanized steel sheet has a certain decorative function, but it cannot adapt to the harsh marine environment in terms of corrosion resistance, erosion resistance, and heat and humidity resistance. climate environment, low service life and high maintenance cost; moreover, the flocking hot-dip galvanized steel sheet has a weak velvet feel and monotonous color, especially with the expansion of the surface area of ​​the flocking surface, the flocking hot-dip galvanized steel sheet cannot achieve good quality. Diffuse reflection effect of light

Abstract

The invention relates to a method for manufacturing a flocking sheet material with corrosion resistance, weather resistance, dew condensation prevention, and certain thermal insulation performance, especially a flocking hot-dip galvanized spray sheet for marine engineering. The method includes the following steps: material selection, dipping anticorrosion liquid, spraying anticorrosion layer, scraping, baking curing treatment, adhesive coating, electrostatic flocking, velvet suction, drying procedure, brushing, spraying, embossing, inspection storage. The product obtained by the method of the present invention has excellent corrosion resistance, good wear resistance, excellent erosion resistance, good heat and humidity resistance, stable long-term use performance in a marine environment with high salt spray concentration, long service life, and strong velvet feeling , bright and eye-catching colors, soft touch, noise reduction, sound absorption, light absorption, heat preservation, passed the national building material fire protection level B‑1 certification, and passed 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 hot-dip galvanized spray plate for marine engineering. Background technique [0002] The production process of flocking hot-dip galvanized steel sheet is the production process of coating a layer of flocking glue on the surface of hot-dip galvanized steel sheet 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-dip galvanized steel sheet not only has the characteristics of high strength, durability and can be recycled many times, but also has sound insulation and heat preservation, strong sealing, and is easy to use. Convenient, concise, practical and beautiful. In moder...
