Problems solved by technology

Although organic antibacterial agents can inhibit mold, the existence of organic antibacterial agents is relatively harmful to the human body and has short validity periods.
Inorganic antibacterial agents have been gradually developed in recent years, and the most widely used are nano-silver ion inorganic composite antibacterial agents and nano-zinc oxide; however, the silver ion antibacterial agents are easily oxidized and discolored, affecting the original color and brightness of the product, and Its antibacterial performance is reduced; and nano-magnesia has long-lasting and broad-spectrum antibacterial activity, which can overcome the problems of high cost, easy discoloration, poor stability, and biological toxicity of silver-based antibacterial materials, and can also make up for the low antibacterial efficiency of photocatalytic antibacterial materials. The lack of dependence on ultraviolet light is a safe, non-toxic, environmentally friendly, and antibacterial material with great application potential
However, at present, magnesium oxide is mainly used for antibacterial coatings, and there are shortcomings such as uneven coating and poor antibacterial ability. It is necessary to overcome the above technical defects when applying it to edge banding

preparation example Construction

[0036] The invention provides a preparation method of antibacterial edge banding, comprising;

[0037] S1. Provide raw materials such as PVC resin, lubricant, additives, toner, and nano-magnesium-based active factor antibacterial materials, mix them evenly in a powder machine, and use a parallel twin-screw granulator to make granules;

[0038] S2, the granules are extruded through a conical twin-screw extruder at 160-170°C, and textured during the shaping process and evenly coated with a bonding agent on the back to obtain a substrate;

[0039] S3, printing on the substrate to obtain the antibacterial edge banding.

[0040] In this embodiment, the prepared antibacterial edge banding is added with nano-magnesium-based active factor antibacterial materials during the powdering process, and the antibacterial material has a small and uniform content, low cost, excellent antibacterial effect, and does not affect the performance of the edge banding.

[0041] Further, in the micelle...

Embodiment 1

[0056] Get dolomite (magnesia content 20%), by calcination, digestion, adopt carbon dioxide carbonization to realize calcium and magnesium separation and obtain heavy magnesium water (containing magnesium bicarbonate 30g / L), add 1.5% aluminum nitrate (mass) in heavy magnesium water ratio) and 1% polyacrylamide (mass ratio), stirred evenly, pumped into the flash tank, under the action of high-speed rotation, the mixed solution was atomized, and in reverse contact with hot air heated to 200 ° C, quickly Dry to obtain composite powder. The composite powder is calcined in an electric furnace for 1 hour at a temperature of 600°C, and the carbon dioxide generated during the calcining process is further recovered. The antibacterial powder obtained by calcination is ball milled in a corundum ball mill tank at a speed of 400r / min for 1 hour to obtain a nano-magnesium-based active factor antibacterial material with a diameter of less than 50 nanometers.

Abstract

The invention provides an antibacterial edge band and a preparation method and application thereof.The method includes the steps that PVC resin, a lubricant, auxiliaries, toner and a nano magnesium-based active factor antibacterial material are evenly mixed in a powdering machine, colloidal particles are prepared through a parallel twin-screw granulator, and the addition amount of the nano magnesium-based active factor antibacterial material is 0.5-1%; and extruding and molding the colloidal particles by a conical double-screw extruder at 160-170 DEG C, pressing textures, and printing to obtain the antibacterial edge band. The prepared nano magnesium-based active factor antibacterial material for the antibacterial edge band is small in mixing amount, uniform, low in cost and excellent in antibacterial effect, and the performance of the edge band is not affected.

Description

technical field [0001] The invention relates to the technical field of home decoration materials, in particular to an antibacterial edge banding and its preparation method and application. Background technique [0002] Edge banding is an essential decoration material in the process of interior decoration, which can protect, decorate and beautify the sections of furniture and boards. Most of the existing edge bandings are PVC edge banding. However, although the edge banding has good heat resistance and corrosion resistance, the edge banding is very easy to absorb microorganisms and dust in the air during the actual use after installation. Once the microorganisms accumulate too much, it will not only damage the edge banding The beauty of the strips can also cause harm to the human body. [0003] In order to solve the above problems, it is necessary to perform antibacterial treatment on the edge banding. Although organic antibacterial agents can inhibit mold, the existence of...
