Corrosion-resistant elevator color-coated sheet

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.

[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, and the air volume is large. There are often corrosive particles that will be adsorbed on the surface of the elevator board, especially at the joints of the elevator board. After corrosion, it will damage the elevator. The connection stability of the board has a certain influence
