Soybean formaldehyde-free glue and PP film-faced composite floor and preparation method thereof |
| abstract |
The invention provides a manufacturing method of a PP film veneered composite floor, the composite floor comprises a PP film surface layer, an aldehyde-free adhesive layer and a multi-layer base material layer from top to bottom, and the manufacturing method comprises the following steps: carrying out plasma and coating treatment on the back of the PP film to obtain a PP film surface layer; coating the soybean formaldehyde-free glue into a criss-cross assembly, and preparing a multi-layer substrate layer after cold pressing and hot pressing; and coating an aldehyde-free adhesive on the front surface of the multilayer substrate layer, then adhering the front surface of the multilayer substrate layer with the back surface of the PP film, and forming the PP film-faced multilayer composite floor after cold pressing and hot pressing. |
