Abstract

The invention relates to the field of materials, and particularly discloses a composite antibacterial material, a preparation method thereof, an antibacterial mildew inhibitor and application of the antibacterial mildew inhibitor. The composite antibacterial material comprises the following raw material of pyroligneous liquor, propolis and berberine. The composite antibacterial material provided by the embodiment of the invention has excellent antibacterial performance, the pyroligneous liquor, the propolis, the berberine and other pure natural raw material substances are adopted, the cost islow, the compatibility with the environment is high, and the prepared composite antibacterial material has the effects of sterilization and mildew removal, and is suitable for industrial production. The problem that potential safety hazards exist due to the fact that chemical preparations are used in existing bacteriostats for fruits, vegetables and feed is solved. The preparation method providedby the invention is simple, and the raw material substances such as pyroligneous liquor, propolis and berberine adopted by the prepared composite antibacterial material belong to natural components, the growth of various bacteria and moulds can be prevented, and the composite antibacterial material cannot bring side effects to the body after being eaten and used for a long time, enable the safetyof fruits, vegetables and feeds to be higher, and have wide application values and market prospects.

Description

technical field [0001] The invention relates to the field of materials, in particular to a composite bacteriostatic material and a preparation method thereof, a bacteriostatic and antifungal agent and applications thereof. Background technique [0002] During the production, storage, transportation, sale and use of fruits, vegetables and feed, rot and mildew often occur, which not only reduces the nutritional value and product quality of fruits, vegetables and feed, but also affects the health of humans and animals. At present, among the microorganisms known to cause mildew in fruits, vegetables and feed, the most serious and the most numerous are fungi, such as anthracnose, botrytis cinerea, alternaria, penicillium, green mold, etc. Therefore, active preventive measures should be taken to prevent Killing and inhibiting bacteria and mold pollution is an urgent problem to be solved in front of the fruit and vegetable production and animal husbandry industry. [0003] At pres...
