Problems solved by technology

[0002] At present, the number of elevators is increasing, but the hidden problems of elevators are also increasing. Aside from the background equipment of elevators, take the elevator car that people use every day as an example. The surface strength of the elevator board used in the car Low, when transporting some decoration building materials, it is often easy to scratch, causing the surface of the elevator board to be damaged; and in daily maintenance, the elevator board is also very delicate, in order to ensure the brightness of its surfa

Embodiment Construction

[0020] The present invention will be further described in detail below in conjunction with the embodiments, so that those skilled in the art can implement it with reference to the description.

[0021] This case proposes an embodiment of a corrosion-resistant elevator color-coated plate, which is sequentially provided with a top coat, a primer coat, a passivation layer, and a substrate layer from top to bottom;

[0022] The specific material of the substrate layer may not be limited, and is generally galvanized sheet. The specific composition of the passivation layer is also not limited, and the passivation solution and its passivation process also belong to the prior art, and the passivation layer is generally a trivalent chromium skin salt film.

[0023] The top coat comprises the following materials in parts by weight:

[0024]

[0025] Acetylene-butyl acrylate copolymer can improve the bonding strength of epoxy resin and polyurethane resin, and the acetylene molecules ...

Abstract

The invention relates to a corrosion-resistant elevator color-coated sheet. The corrosion-resistant elevator color-coated sheet is sequentially provided with a surface coating, a bottom coating, a passivation layer and a base sheet layer from top to bottom. The surface coating comprises, by weight, 100 parts of epoxy resin, 20-22 parts of acetylene-butyl acrylate copolymer, 5-6 parts of octyl benzoate and 5-6 parts of n-methylacetamide. The bottom coating comprises, by weight, 100 parts of polyurethane resin, 9-10 parts of borax, 4-5 parts of sodium silicate, 10-12 parts of propylene-styrol copolymer, 2-3 parts of gamma-lactam and 2-3 parts of hexamethyl-disilazane. According to the scheme, a traditional elevator color-coated sheet is modified, and various modifying materials are introduced to improve the structure toughness, the surface strength, the corrosion resistance and the scratch resistance of the coatings.

Description

technical field [0001] The invention relates to an elevator color-coated board, in particular to a corrosion-resistant elevator color-coated board. Background technique [0002] At present, the number of elevators is increasing, but the hidden problems of elevators are also increasing. Aside from the background equipment of elevators, take the elevator car that people use every day as an example. The surface strength of the elevator board used in the car Low, when transporting some decoration building materials, it is often easy to scratch, causing the surface of the elevator board to be damaged; and in daily maintenance, the elevator board is also very delicate, in order to ensure the brightness of its surface, the maintenance personnel should often brush Maintenance wax, but the smell of maintenance wax is pungent and not environmentally friendly. The elevator car has been in the elevator shaft for a long time. The environment in the shaft is poor, the humidity is high, a...
