Problems solved by technology

However, the stainless steel panel has poor oil resistance, in addition to poor wear resistance and scratch resistance
Chinese invention patent ZL03123752.5 discloses a method for forming a nano-anti-fouling coating on the surface of stainless steel, but the formed nano-anti-fouling coating has poor bonding force with the stainless steel substrate, and the scratch resistance is not good, so it is difficult to Forms a permanent abrasion and stain resistant protective coating

Abstract

The invention relates to a car wall door sheet and a coating method of the car wall door sheet. The car wall door sheet comprises a stainless steel panel with the thickness being 1.2-2.0 mm, and a chemical conversion layer and a top coat are formed on the outer surface of the stainless steel panel in sequence. The chemical conversion layer is formed by immersing the stainless steel panel in a chemical conversion solution for 5-10 minutes, and the mass of the formed chemical conversion layer is 5-10g / m2. The top coat is formed by coating a surface treating agent on the stainless steel panel provided with the formed chemical conversion layer and then curing the stainless steel panel at the temperature of 120-150 DEG C for 15-30 minutes. The car wall door sheet has high hardness and excellent wear-resistant performance, is not stuck to water or oil substances and has excellent anti-pollution performance.

Description

technical field [0001] The invention relates to the technical field of elevator spare parts materials, more specifically, the invention relates to a car wall door panel and a coating method thereof. Background technique [0002] With the continuous improvement of people's living standards, people's living environment and living standards are also improving. Correspondingly, users have higher and higher quality requirements for elevator products. On the basis that elevator products are fully equipped with normal functions, there are also higher requirements for their appearance, interior and comfort. The car is the car body part used by the elevator to carry passengers or goods and other loads. The car roof is an indispensable part of the car, and it usually consists of parts including a top plate, a car wall and other accessories. Since the car and other parts of the standard passenger elevator or freight elevator are the direct "face" of the elevator, stainless steel is u...
