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 galvanized 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 galvanized sheet has a weak velvet feel and monotonous color, especially with the expansion of the surface area of ​​the velvet surface, the flocked galvanized sheet cannot achieve excellent quality. Diffuse reflection effect of light

Abstract

The invention relates to a manufacturing method for an anticorrosion and weather-resistant flocking panel capable of preventing dropping of dew and having certain heat preservation performance, in particular to a manufacturing method for a flocking zinc aluminized anticorrosion spraying decorated and knurled panel for oceanographic engineering. The manufacturing method comprises the following steps of material selecting, preservative liquid dip-coating, anticorrosive coating spraying, smearing and scrapping, baking and curing treatment, adhesion agent coating, electrostatic flocking, pile sucking, a drying procedure, brushing, spraying decorating, knurling and examining and warehousing. The product manufactured through the method has excellent corrosion resistant performance, good abrasion resistant performance, excellent washout resistant performance, good moisture and heat resistant performance, stable performance when used in the ocean environment where the salt mist concentration is high, long service life, a high upright pile sense, bright and dazzling colors and a soft touch sense, is capable of reducing the noise, absorbing sound and light and preserving heat, is authenticated by national building material fireproofing grade B-1 and passes environmental certification.

Description

technical field [0001] 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 method for manufacturing a flocking galvanized anti-corrosion spray embossed sheet material for marine engineering . Background technique [0002] The production process of the flocking galvanized sheet is to apply a layer of flocking glue on the surface of the galvanized sheet and then plant the 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 galvanized sheet 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 easy to use. Convenient, concise, practical...
