Embodiment 1

[0030] This embodiment provides a kind of manufacture method of antibacterial plastic, it comprises the steps:

[0031] (1) Make inorganic nano antibacterial material powder into inorganic nano antibacterial liquid;

[0032] In this step, in order to achieve long-lasting and efficient antibacterial and mildew removal effects, the inorganic nano-antibacterial material is a nano-particle state material comprising a metal salt, which is preferably composed of the following components by weight:

[0033] 5-30 parts of nano-zinc oxide, 5-30 parts of nano-silver ion antibacterial powder, 0-20 parts of nano-anion powder, 20-50 parts of nano-infrared powder;

[0034] Among them, the antibacterial and antifungal mechanism mainly has the following aspects:

[0035] Sterilization mechanism of nano-zinc oxide:

[0036] 1. Electrostatic adsorption, due to the combination of zinc and oxygen, the electronegativity of the surface of zinc oxide is larger than that of ordinary metal ions, and...

Embodiment 2

[0069] This embodiment provides an antibacterial plastic prepared by the method of Embodiment 1, which includes a thermoplastic plastic substrate, and the plastic substrate is also impregnated with an inorganic nano antibacterial material.

[0070] Wherein, this plastic base material is the PP plastic that weight component is 99.5%, and the weight component is the inorganic nanometer antibacterial material of 0.5%, and the inorganic nanometer antibacterial material that the proportioning number is AB-01 in the embodiment one is selected for use in this embodiment Material.

Embodiment 3

Abstract

The invention relates to a method for preparing an antibacterial plastic and the antibacterial plastic. The preparation method comprises the following steps: preparing an inorganic nano antibacterialliquid from an inorganic nano antibacterial material of nano granules; and in high-pressure high-temperature reaction kettle, sequentially sucking off air in a plastic, performing primary heating to implement preheating, performing pressurizing, and performing sufficient heating to thoroughly diffuse the inorganic nano antibacterial material into the plastic, and further performing depressurizingto suck off the air. Therefore, the inorganic nano antibacterial material of the nano granules is infiltrated into the plastic, plastic granules have antibacterial functions, and meanwhile, injectionmolding production can be implemented; and due to infiltration of the inorganic nano antibacterial material in the antibacterial plastic provided by the invention, an antibacterial effect can be achieved, and the problem that a conventional plastic has no antibacterial function is solved.

Description

technical field [0001] The invention belongs to the field of antibacterial technology, and in particular relates to a method for manufacturing antibacterial plastics and antibacterial plastics. Background technique [0002] Bacteria will exist in large numbers in relatively airtight or poorly ventilated places. In high-temperature and high-humidity areas in the south, food workshops in special environments, etc., mold and bacteria are easy to breed. Bacteria are also easy to form on the surface of packaging materials, which affects the use and environmental health. Various packaging materials and daily-use products such as home appliances require antibacterial and anti-mildew functions, which has greatly developed the technology of anti-bacterial and anti-mildew materials. Research and development of new, efficient, non-toxic (or low-toxic), durable antibacterial materials has important practical significance and broad market prospects. [0003] Existing antibacterial mater...
