Abstract
Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of rail transit operation management, and more particularly to a floor cloth surface color changing and renovating method. BACKGROUND
[0002] At present, with the acceleration of urbanization process and the expansion of subway network scale, the daily passenger flow of rail vehicles is large, and problems such as high frequency wear of the car floor and erosion of cleaning agents have become difficult points in rail transit operation management.
[0003] However, the traditional floor waxing process has a short maintenance cycle (45-60 days), a high labor cost of up to 73%, and a wear amount of 0.06g, which has been difficult to meet the durability and environmental protection requirements in high-density passenger flow scenarios.
[0004] Therefore, how to develop a floor cloth surface color changing and renovating method is a problem to be solved by those skilled in the art. SUMMARY
[0005] Therefore, the purpose of the present application is to provide a floor cloth surface color changing and renovating method to solve the problems of dirt accumulation, dull color and impact on passenger driving experience of the traditional rail vehicle floor cloth with the increase of use time and cleaning frequency in the prior art.
[0006] In order to achieve the above purpose, the present application adopts the following technical solutions:
[0007] A floor cloth surface color changing and renovating method, specifically comprising the following steps:
[0008] (1) first clean the floor cloth surface with a weak alkaline cleaning agent, then use a single-wiping machine with different wear degrees for mechanical grinding, and finally rinse with clean water and dry;
[0009] (2) first apply an interfacial adhesion promoter to the surface of the floor cloth, then use an electric rolling machine to roll and coat polyurethane color-changing paint, and finally use an electric rolling machine to roll and coat high-strength polyurethane paint, and the process is completed.
[0010] Further, in the above step (1), the weak alkaline cleaning agent comprises the following raw materials by weight: 1-2 parts of a gum removing agent, 1-2 parts of an oil removing agent, and 1-4 parts of a wax removing water, preferably: 1 part of a gum removing agent, 1 part of an oil removing agent, and 2 parts of a wax removing water.
[0011] The further beneficial effect of the above is that, unlike the usual cleaning of the floor surface with a neutral cleaner, the present application uses a weak alkaline cleaning agent to clean the floor cloth surface according to the degree of dirt, adjusts the proportion of the cleaning agent, such as degreaser, oil remover, and wax remover, to clean and polish the floor cloth surface, and uses a single rubbing machine with different abrasion degrees to mechanically grind and completely remove the oil and adhesive residues on the floor cloth surface, and completely remove the oil stains and stains on the floor cloth surface that are not conducive to the adhesion of the coating.
[0012] Further, in the above step (1), the drying temperature is 23-27℃, the wind speed is 2m / s, and the moisture content of the floor cloth is ≤8%.
[0013] The further beneficial effect of the above is that the cleaning agent residue on the floor is removed by rinsing with clean water and drying. The cleaning effect is verified by the white cotton wiping method (no visible stain transfer), and the surface energy tester is used to ensure that the critical surface tension of the substrate is ≥40mN / m, which provides an interface guarantee for the adhesion of the coating.
[0014] Further, in the above step (2), the interface adhesion promoter is 3M interface agent.
[0015] The further beneficial effect of the above is that the interface adhesion promoter is applied to the surface of the floor cloth to achieve the purpose of firm adhesion of the subsequent coating and ensure the service life of the coating. The interface adhesion promoter can effectively reduce the surface energy of the floor cloth, increase the wettability of the subsequent polyurethane coating and the floor cloth, and improve its adhesion.
[0016] Further, in the above step (2), the polyurethane color-changing coating includes the following raw materials by weight: 1-4 parts of polyurethane color paint and 1 part of curing agent, preferably: 4 parts of polyurethane color paint and 1 part of curing agent.
[0017] The further beneficial effect of the above is that the polyurethane color-changing coating is applied by electric rolling to achieve the purpose of color changing. During color matching, decorative materials such as bright flashing particles and small color particles can be added to achieve the purpose of beauty, etc.
[0018] Further, in the above step (2), the high-strength polyurethane coating includes the following raw materials by weight: 1-4 parts of polyurethane topcoat and 1 part of curing agent, preferably: 2 parts of polyurethane topcoat and 1 part of curing agent.
[0019] The further beneficial effect of the above is that the high-strength polyurethane coating is applied by rolling to protect the color-changing layer and prolong the service life. Before mixing the coating, functional particles such as wear-resistant particles and fire-resistant particles can be added to improve wear resistance and fire resistance, etc.
[0020] Furthermore, in step (2) above, the roller coating method is as follows: an electric roller coating machine is used to uniformly discharge and coat the material; and a grid cross roller brush method is adopted. First, the coating is poured in 1m×1m units according to the standard of 50g / m2 to ensure that the coating amount per unit area is ≤±5%; then, a cross roller brush is used. First, the horizontal roller brush is used at a speed ≤1m / s, and then the longitudinal orthogonal coating is used at an angle of 85°-95°. Through the squeezing action of the short-bristled roller brush with a bristle length of 3-5mm, the average thickness of the coating is 0.03mm.
[0021] The further beneficial effect of the above-mentioned method is that, by using an electric roller coating machine to evenly distribute the material and employing a segmented cross-brush coating method, the coating is evenly applied to the surface of the flooring fabric, and after drying, it firmly adheres to the flooring fabric. This method achieves surface coating treatment for the flooring fabric, resulting in a more aesthetically pleasing and easier-to-clean flooring fabric, thus extending its service life.
[0022] As can be seen from the above technical solution, compared with the prior art, the beneficial effects of the present invention are as follows:
[0023] 1. The method of the present invention can give the floor cloth a brand new look and increase the overall aesthetics of the carriage by changing the color.
[0024] 2. Using a mild alkaline cleaner and an interface adhesion promoter can completely remove dirt and oil stains from the surface of the floor cloth, ensuring that the coating can firmly adhere to the surface of the floor cloth.
[0025] 3. The use of a high-strength polyurethane coating on the surface greatly extends the service life of the floor cloth and makes it easier to clean, reducing the labor intensity of cleaning workers and the cleaning costs of the subway operating department.
[0026] 4. The renovated flooring not only has improved performance, but also looks cleaner and more attractive, providing passengers with a better riding experience and enhancing the city's brand image. Detailed Implementation
