Antibacterial plastic master batch and manufacturing method thereof and antibacterial chopping board prepared from antibacterial plastic master batch

Abstract

The invention discloses an antibacterial plastic master batch and a manufacturing method thereof and an antibacterial chopping board prepared from the antibacterial plastic master batch. The master batch is prepared by mixing and granulating an antibacterial master batch composition, wherein the composition comprises 15 to 95 weight parts of plastic component, 1 to 25 weight parts of antibacterial agent component and coupling agent. The method for preparing the antibacterial plastic master batch comprises the following steps of: treating plastic raw materials into plastic powder with particle diameter of 1 to 165 microns, wherein the plastic powder is used as the plastic component; pressing, mixing and kneading the plastic component, the antibacterial agent and the coupling agent for 10 to 40 minutes at the temperature of between 75 and 138 DEG C to form semi-finished product raw materials; and mixing the semi-finished product raw materials at the temperature of between 100 and 180 DEG C, extruding, and thus obtaining the granular antibacterial plastic master batch. The antibacterial chopping board prepared from the antibacterial plastic master batch obtained by the preparation method has better antibacterial effect.

Description

technical field [0001] The invention relates to a plastic masterbatch and a cutting board made therefrom, in particular to an antibacterial plastic masterbatch, a manufacturing method thereof and an antibacterial cutting board made therefrom. Background technique [0002] Due to the characteristics of easy molding, light weight, and stability, plastics have become raw materials for various daily necessities, especially in bathrooms, kitchens and other humid environments. It is widely used as an ideal material for bathroom supplies and kitchen supplies. [0003] However, most of the bathroom or kitchen items made of plastic materials do not have additional functions such as antibacterial, deodorizing, or purification. After long-term use, they still have the disadvantages of easy breeding of bacteria, discoloration, or odor, especially for kitchen items such as cutting boards. , because it is often used to process various raw food, cooked food and other ingredients, even if ...

Problems solved by technology

[0003] However, most of the bathroom or kitchen items made of plastic materials do not have additional functions such as antibacterial, deodorizing, or purification. After long-term use, they still have the disadvantages of easy breeding of bacteria, discoloration, or odor, especially for kitchen items such as cutting boards. , because it is often used to process various raw food, cooked food and other ingredients, even if it is washed after use, it is still easy to become a hotbed for bacteria to adhere and breed. In addition, after a period of use, there are usually many knife marks on the surface, which is not beautiful In addition, the knife marks are likely to become a breeding ground for a large number of bacteria to hide and multiply. In this way, it is easy to cause food pollution and may endanger human health, so it is not in line with the principles of safe and hygienic use.

Although there are plastic products with antibacterial functions on the market, such as antibacterial cutting boards, most of these products provide antibacterial functions by directly adding a predetermined amount of antibacterial agents to the plastic raw materials. Due to the high cost of antibacterial agents, it is difficult to Compared with the amount of plastic raw materials, the amount added is usually very small and the antibacterial effect is not clear. In addition, the direct addition of antibacterial agents to plastic raw materials is prone to uneven distribution of antibacterial agents, and the produced products Some plastic products only have antibacterial agent distribution in some local areas, and the area where antibacterial agent is not distributed is still easy to adhere to bacteria, which leads to the incomplete antibacterial effect of the plastic product and needs to be improved
