Abstract

The invention relates to a method for processing a mouldproof and antibacterial film, comprising the following steps of: firstly processing a mouldproof and antibacterial agent into powder, and then mixing with a TPU (Thermoplastic polyurethane) film raw material; after five-stage type heating mixing in a screw rod barrel, carrying out blow molding by using a film blowing machine mould to form a tubular film, and laminating the cooled tubular film into a double-layer mouldproof and antibacterial film by using a forming guide wheel. The method accomplishes the mouldproof and antibacterial property of the film in the production and manufacturing process of the film so that the mouldproof and antibacterial effect of the film is more durable and is also improved, and through ASTM (American Society for Testing Material) E2149-01 test, the mouldproof and antibacterial effect can reach 98%.

Description

technical field [0001] The invention relates to a method for synthesizing a film, in particular to a method for processing an anti-mildew and antibacterial film. Background technique [0002] In order to make the fabric play the role of waterproof and breathable, it is usually necessary to carry out anti-mildew and antibacterial treatment to the fabric. Invention patent CN200510063420.5 discloses a method for manufacturing a polyurethane multilayer film with antibacterial and antifungal properties. The method utilizes an adhesive layer to bond a breathable polyurethane film on the surface of a fabric, and then coats a resin film containing a surface modifier and an antifungal and antibacterial agent on the surface of the polyurethane film, so that the resin film and the polyurethane film are integrated. The fabric forms a polyurethane multilayer film fabric. Although the film prepared by this method has anti-mildew and anti-bacterial effect, because the coated film will fa...
