Description

technical field [0001] The invention belongs to the technical field of foam plastics, and in particular relates to a foam plastic with antibacterial and antifungal functions. Background technique [0002] Foamed plastics, also known as microporous plastics, are plastics that are filled with numerous interconnected or disconnected micropores that significantly reduce the apparent density. Foam plastic is a polymer material with plastic as the basic component and contains a large number of bubbles, so it can also be said to be a composite plastic filled with gas. Foam plastic has many excellent properties such as light weight, heat insulation, sound absorption, shock absorption, etc. It is a kind of polymer material formed by a large number of gas micropores dispersed in solid plastic, and has an extremely wide range of applications. [0003] Because the foamed plastic material contains necessary nutrients such as bacteria and molds, under suitable temperature and humidity co...
