Example Embodiment

[0026] Example 1

[0027] An antibacterial, mildew-proof and deodorizing composite film, comprising a base material on which a layer of antibacterial film is compounded; the antibacterial film is composed of an antibacterial agent and plastic, the content of the antibacterial agent is 1wt%, and the antibacterial agent is composed of water It is composed of 6 parts of salicylanilide and 4 parts of imidazole. Prepared as follows:

[0028] refer to figure 1 , after stirring the antibacterial agent and plastic particles evenly, the suction machine sucks the material into the hopper 2, and then passes through the screw extruder 1, and the screw extrudes. During this process, the material is melted into a liquid by heating; After that, these melts (melted liquids) are filtered through the filter screen 3, and then flow out from the loose film opening of the die head 5 evenly through the melt pipeline 4; On the base material on the top, the melt is casted to form a film, and the c...

Example Embodiment

[0029] Example 2

[0030] The difference between this example and Example 1 is that the composition of the antibacterial film is different. In this example, the antibacterial film is composed of an antibacterial agent and plastic, the content of the antibacterial agent is 1 wt %, and the antibacterial agent is composed of salicylic acid It consists of 4 parts of aniline and 6 parts of imidazole.

Example Embodiment

[0031] Example 3

[0032] The difference between this example and Example 1 is that the composition of the antibacterial film is different. In this example, the antibacterial film is composed of an antibacterial agent and plastic, the content of the antibacterial agent is 1 wt %, and the antibacterial agent is composed of salicylic acid It consists of 8 parts of aniline and 2 parts of imidazole.

Abstract

The invention provides an antibacterial, mildew-proof and deodorizing composite film, which comprises a substrate, on which a layer of antibacterial film is compounded; the antibacterial film is composed of antibacterial agent and plastic, and the content of antibacterial agent is 0.1-10wt%; In parts by weight, the antibacterial agent consists of 1-10 parts of salicylanilide and 1-10 parts of imidazole. After the antimicrobial agent and plastic particles are evenly stirred, they are fed into a screw extruder and melted and extruded; the melt is cast into a film, and then hot pressed and pasted on the substrate to form a composite film. The composite membrane provided by the invention is safe and reliable, and the antibacterial agent can be used for acute oral LD 50 >10000mg/kg (rat); strong antibacterial properties, especially in high humidity environment; stable performance, very stable in acid-base solution and ultraviolet rays, non-corrosive container, slightly soluble in water, medicine Long-lasting effect; transparency has no effect.

Description

technical field [0001] The invention relates to a composite membrane, in particular to an antibacterial, mildew-proof and deodorizing composite membrane and a preparation method thereof. Background technique [0002] Food protein is decomposed by proteolytic enzymes produced by spoilage bacteria, and then degrades to low-molecular compounds in turn to generate various toxic substances and unpleasant odor substances. Therefore, in the field of food, antibacterial and anti-mildew are extremely important aspects . Usually, the antibacterial and mildew proof of packaged food is achieved by adding chemical agents such as preservatives to food. The main function of preservatives is to inhibit the growth and reproduction of microorganisms, to prolong the storage time of food, and to inhibit the corruption of substances. Food preservatives can inhibit microbial activity and prevent food spoilage, thereby prolonging the shelf life of food and maintaining the original quality and nu...
