Detailed Description

In specific implementation, the preparation method of the antibacterial and antiviral PVC plastic foaming pad comprises the following steps:

preparing effective amounts of PVC resin powder, calcium carbonate, a calcium core stabilizer, a foaming agent and antibacterial nano particles;

step two, uniformly mixing the raw materials prepared in the step one, adding a plasticizer, and uniformly stirring to form a pasty mixture;

step three, coating the paste mixture obtained in the step three on a mesh by adopting a continuous blade coating method, and after the coating is finished, putting the mesh into a foaming furnace for plasticizing and foaming and then molding;

and step four, circularly cooling and shaping the product formed in the step three to obtain the PVC plastic foaming pad with the antibacterial and antiviral functions.

The working principle of the invention is as follows: the application provides a preparation method of an antibacterial and antiviral PVC plastic foaming pad, which comprises the steps of uniformly mixing effective amounts of PVC resin powder, calcium carbonate, a calcium core stabilizer, a foaming agent and antibacterial nano particles, adding a plasticizer, and uniformly stirring to form a pasty mixture; and (3) coating the pasty mixture on a mesh by adopting a continuous blade coating method, plasticizing and foaming in a foaming furnace, then molding, and circularly cooling and shaping to obtain the foaming pad with good antibacterial and antiviral effects.

In the actual production process, the antibacterial and antiviral PVC foaming pad is obtained by adding the antibacterial and antiviral product according to a specific proportion without changing the existing production process and raw material conditions of customers and then carrying out production.
