Problems solved by technology

Some existing products such as iron powder magnetic paint, iron powder is easy to rust, lose magnetism, and produce rust spots, and it cannot be applied as easily as commonly used paints, which restricts the application of magnetic whiteboards
However, the writing and erasing performance on the surface of the whiteboard wall is not durable, and some necessary tapes are easy to leave residual glue on the surface, which is not easy to clean

Embodiment 1

[0068] The preparation process of the magnetic writing wall of the present embodiment includes the following process steps:

[0069] 1) Leveling of the base layer of the wall surface: plastering with high-strength putty to repair and level the base layer of the wall surface;

[0070] 2) Apply the water-based reinforcing sealant to the leveled wall surface in step 1), penetrate and reinforce and seal the base layer, and after the surface is dry, lightly sand the surface to remove the burrs;

[0071] 3) Apply the water-based magnetic tough glaze paint evenly on the surface of the base layer that has been sealed in step 2) with a roller, and apply 3 coats evenly. Under the temperature condition of 23°C, the time between two coats is 2h;

[0072] 4) Evenly apply the water-based writing tough glaze paint on the surface of the water-based magnetic suction tough glaze coating formed in step 3) with a roller, and apply 2 coats evenly. After 4 hours, a magnetic writing wall is obtaine...

Embodiment 2

[0083] The preparation process of the magnetic writing wall of the present embodiment includes the following process steps:

[0084] 1) Leveling of the base layer of the wall surface: plastering with high-strength putty to repair and level the base layer of the wall surface;

[0085] 2) Apply the water-based reinforcing sealant to the leveled wall surface in step 1), penetrate and reinforce and seal the base layer, and after the surface is dry, lightly sand the surface to remove the burrs;

[0086] 3) Apply the water-based magnetic tough glaze paint evenly on the surface of the base layer that has been sealed in step 2) with a roller, and apply 3 coats evenly. Under the temperature condition of 23°C, the time between two coats is 2h;

[0087] 4) Evenly apply the water-based writing tough glaze paint on the surface of the water-based magnetic suction tough glaze coating formed in step 3) with a roller, and apply 2 coats evenly. After 4 hours, a magnetic writing wall is obtaine...

Embodiment 3

[0098] The difference between this embodiment and embodiment 1 is that, in the water-based magnetically attractive tough glaze paint, the mass ratio of component A to component B is 1:11, and the others are the same as in embodiment 1.

Abstract

The invention discloses a magnetic suction writing wall and a preparation process thereof. The magnetic writing wall of the present invention is prepared from water-based magnetic-absorbing tough glaze paint and water-based writing tough glaze paint. The magnetic writing wall of the present invention is easy to paint and construct, has firm adhesion to various substrates, strong ferromagnetism of the coating, fast surface-drying speed, excellent writing and erasability, high scratch resistance hardness, and no damage when wiping with solvents. It can fully meet various requirements for the performance of whiteboards in actual use, and can completely replace metal whiteboards and glass whiteboards, reducing the waste of financial and material resources, reducing unnecessary space occupation, and exerting good economic and social benefits.

Description

technical field [0001] The invention relates to the technical field of building decoration materials, and relates to a magnetic writing wall and a preparation process thereof. Background technique [0002] In teaching and office spaces, the writing whiteboard is an indispensable facility, which can be a hanging writing whiteboard or a made writing whiteboard wall to meet the writing requirements. The whiteboard wall can meet the needs of writing, and the user also needs the wall to have the function of magnet adsorption, and the performance of adhesive tape without leaving any glue residue. Some existing products, such as iron powder magnetic paint, iron powder is easy to rust, loses magnetism, produces rust spots, and cannot be easily applied like commonly used paints, which restricts the application of magnetic whiteboards. However, the surface writing and erasing performance of the whiteboard wall is not durable, and some necessary tapes are easy to leave residual glue o...
