However, natural antibacterial agents are usually extracted from a plant, animal or organism. The antibacterial active ingredient is relatively single, and the antibacterial spectrum is narrow. The compatibility between it and the polymer is poor, and there are problems such as uneven dispersion and easy agglomeration. Antibacterial ingredients are easy to precipitate during use, and the antibacterial effect cannot last

Embodiment 1
[0034] 1. Raw material preparation:
[0035] ①Preparation of loess powder: put the loess into the calciner, calcinate at 300°C for 2.5 hours, take it out and pulverize it, pass it through an 80-mesh sieve, add a sodium hydroxide solution with a concentration of 1 to 25wt% that is 7 times the weight of the loess, and put it in a pH value of 9.0 Stirring and reacting at a temperature of 65°C for 3h, lowering the temperature to 50°C, adding an appropriate amount of 0.5-20wt% acetic acid solution to adjust the pH value to neutrality, stirring for 30min, filtering, and washing the filter cake with deionized water for 3 times. Blast drying at 90°C, grinding through a 1200-mesh sieve to obtain white loess powder;
[0036] ②Preparation of honeysuckle leaves, fig leaves, and emblica cotyledon extracts: collect fresh and non-rotten honeysuckle leaves, fig leaves, and emblical leaves, remove impurities respectively, wash, dry, cut into 1cm sections, and place them in each In the corresp...

[0046] 1. Raw material preparation:
[0047] ① Preparation of loess powder: put loess into calciner, calcined at 350° C. for 2 hours, take out and pulverize, pass through 80 mesh sieve, add 6 times the weight of loess with a concentration of 1 to 25 wt % sodium hydroxide solution, at pH 9.0, Stir the reaction at 70°C for 2 hours, lower the temperature to 50°C, add an appropriate amount of 0.5-20wt% acetic acid solution to adjust the pH value to neutral, stir for 30 minutes, filter, and wash the filter cake with deionized water 3 times. Blast drying at ℃, grinding through a 1200 mesh sieve to obtain white loess powder;
[0048] ② Preparation of honeysuckle leaves, fig leaves, and emblica cotyledon extracts: collect fresh and non-rotten honeysuckle leaves, fig leaves, and emblica cotyledon leaves, remove impurities respectively, wash, dry, cut into 2cm sections, and place them in each In the corresponding homogenizer, add ethanol with a concentration of 3 times the weight of th...

Abstract
The invention provides an anti-bacterial cutting-chopping-resistant plastic cutting board and a preparation method thereof. According to a formula, the plastic cutting board comprises the following raw materials in percentage by weight: 70-90% of a polymer, 5-17% of a natural anti-bacterial agent, 3-8% of a cutting-chopping-resistant agent and 2-5% of a coupling agent, wherein the natural anti-bacterial agent is prepared from 75-90% by weight of loess powder, 3-9% by weight of a honeysuckle leaf extractive, 2-6% by weight of a ficus carica leaf extractive and 5-10% by weight of an emblic leaf extractive; the cutting-chopping-resistant agent is prepared from 30-60% by weight of erucicamide, 15-30% by weight of acer truncatum seed oil and 25-40% by weight of dimethyl polysiloxane. Accordingly, the plastic cutting board is prepared by multi-approach processing means, and has not only anti-bacterial, broad-spectrum, efficient, lasting and safe effects, but also a far infra-red radiation effect and the functions of self-cleaning and environmental purification when being high in aging resistance and abrasion resistance and low in possibility of cutting marks, so that the using safety and the dietetic hygiene are improved.
Description
technical field [0001] The invention relates to a kitchen utensil, in particular to an antibacterial and cut-resistant plastic chopping board and a preparation method thereof. Background technique [0002] Chopping boards, also known as cutting boards and vegetable piers, are indispensable kitchen utensils for people to chop meat, vegetables and other foods. Traditional cutting boards are mostly wood cutting boards, which have the advantages of natural, high density, non-toxic and corrosion-resistant. The disadvantages are bulky, high water absorption, easy to mildew and deterioration, and the surface hardness is low, easy to produce knife marks, shavings and slag, and the surface is concave. In addition, the wood itself is easy to be damp and cracked, and it is easy to breed bacteria and mold. and other pathogenic microorganisms, contaminating food and seriously endangering human health. Simultaneously, the extensive use of wooden chopping boards just must cut down a large...
