[0026] Example 1:
[0027] Please refer to figure 1 , A method for preparing sound insulation hard PVC floor, specifically, attaching 4 layers of PE foam board with a thickness of 1.0mm foaming material to the back of ordinary PVC floor to prepare, including the following steps:
[0028] (1) Negative film production: After the raw materials are qualified, they are drawn through the process of cold mixing and hot mixing, banburying, four-roll calendering, cooling, and winding according to the common PVC floor formula and film production method. Various required specifications and thickness of the film;
[0029] (2) Continuous line bonding: After the temperature rises to the specified value, the material is threaded layer by layer in the order of the film, the surface layer, the color film, and the transparent sheet. The number of layers depends on the thickness of the prepared floor and the thickness of the transparent sheet. The requirements (0.3mm), etc. are determined, and the te...

[0042] Example 2:
[0043] Please refer to figure 1 , A method for preparing sound insulation hard PVC floor, specifically, attaching 4 layers of PE foam board with a thickness of 2.0mm foam material on the back of ordinary PVC floor to prepare, including the following steps:
[0044] (1) Negative film production: After the raw materials are qualified, they are drawn through the process of cold mixing and hot mixing, banburying, four-roll calendering, cooling, and winding according to the common PVC floor formula and film production method. Various required specifications and thickness of the film;
[0045] (2) Continuous line bonding: After the temperature rises to the specified value, the material is threaded layer by layer in the order of the film, the surface layer, the color film, and the transparent sheet. The number of layers depends on the thickness of the prepared floor and the thickness of the transparent sheet. The requirements (0.5mm), etc. are determined, and the tensi...

[0058] Example 3:
[0059] Please refer to figure 1 , A method for preparing sound insulation hard PVC floor, which specifically prepares by adhering 4 layers of PS foam board with a thickness of 1.0mm foam material on the back of ordinary PVC floor, including the following steps:
[0060] (1) Negative film production: After the raw materials are qualified, they are drawn through the process of cold mixing and hot mixing, banburying, four-roll calendering, cooling, and winding according to the common PVC floor formula and film production method. Various required specifications and thickness of the film;
[0061] (2) Continuous line bonding: After the temperature rises to the specified value, the material is threaded layer by layer in the order of the film, the surface layer, the color film, and the transparent sheet. The number of layers depends on the thickness of the prepared floor and the thickness of the transparent sheet. The requirements (0.5mm), etc. are determined, and the ...
