Example Embodiment
[0036] Example 1:
[0037] A method for producing 3D leather with three-dimensional effect, including the following steps:
[0038] A. Mesh screen production: Make a hollow mesh screen according to the required effect picture, and the hollow part of the mesh screen is the required effect picture part;
[0039] B. Prepare 3D layer slurry, and adjust the consistency to 6# Ford cup for 90±2 seconds, put the mesh screen on the leather blank, pour the prepared 3D layer slurry on the mesh screen, and brush back and forth with a brush. Make the 3D layer slurry enter the surface of the skin blank from the hollow part of the mesh screen; then remove the mesh screen and dry and cool at 110-120°C to form a 3D layer;
[0040] C. Prepare the primer slurry, and adjust the consistency to 4# Ford Cup 48±3 seconds, apply the prepared primer slurry on the surface of the 3D layer of the leather blank by roller coating, the coating amount is 8.0±0.5 g / sqft; then, drying and cooling are carried out at 11...
