Abstract

The invention belongs to the technical field of steel structure surface modification, and particularly relates to a fingerprint-resistance layer for a goods shelf and a preparing method. The fingerprint-resistance layer is composed of a fingerprint-resistance coating layer and an epoxy resin coating layer; the epoxy resin coating layer coats the steel surface of a carbon structure of the goods shelf, and the fingerprint-resistance coating layer coats the epoxy resin coating layer. The goods shelf member coated with the epoxy resin coating layer is coated with the fingerprint-resistance coatinglayer, the defects that traditional fingerprint-resistance coatings or coatings directly coat galvanized steel sheets, thus zinc layers for production of goods shelves are easily molten, the connecting strength of welding points is lowered, and shedding easily occurs are overcome, and the weather fastness, wear resistance and fingerprint resistance of the surface of the goods shelf are improved.

Description

technical field [0001] The invention belongs to the technical field of surface modification of steel structures, and more specifically relates to a fingerprint-resistant layer for shelves and a preparation method thereof. Background technique [0002] The storage of goods on shelves plays an important role in supermarkets and warehouses. Since shelves are often used in humid and acidic / alkaline environments, and because items are often moved or placed, they frequently rub against the surface of the shelf, and electrostatic spraying is usually used to coat the bottom material of the shelf with a certain thickness of paint, which can Improve the corrosion resistance and wear resistance of the shelf to a large extent. [0003] For some high-end supermarket or shopping mall shelves, customers will often touch the surface of the shelf, resulting in more fingerprints remaining on the surface of the shelf, affecting its appearance. At present, anti-fingerprint paint is usually co...
