Problems solved by technology

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. It has poor compatibility with polymers, and has defects such as uneven di

Embodiment 1

[0030] 1. Raw material preparation:

[0031] ① Preparation of loess powder: collect a certain amount of loess and add hydrochloric acid solution with a concentration of 0.5 to 45 wt% at a solid-to-liquid weight ratio of 1:10 for mixing and pulping, control the pH value of the slurry to 5, and place it in a closed acid-resistant reactor. React at 150°C for 5 hours, discharge, cool, wash with deionized water until neutral, dry, calcinate at 500°C for 1 hour, cool, and grind to a particle size of 1200 mesh with a ceramic bead mill to obtain white loess powder;

[0032] ②Preparation of extracts of pomegranate peel, chestnut shell, and false cohosh root: collect non-rotten pomegranate peel, chestnut shell, and false cohosh root, wash them separately, dry them, crush them into 25-mesh fragments, and then pour them into the corresponding In the extraction tank, add 9 times the weight of the fragments in ethanol with a concentration of 80wt%, soak for 2 hours, extract at 65°C for 50 m...

Abstract

The present invention provides an antibacterial and anti-aging plastic container and a preparation method thereof, wherein the raw materials of the plastic chopping board in the formula comprise, by weight, 75-95% of a polymer, 3-20% of a natural antibacterial agent, 1.2-3% of semen arecae seed, and 0.8-2% of a coupling agent, and the natural antibacterial agent is prepared from 75-90% by weight of loess powder, 5-15% by weight of a pomegranate peel extract, 3-6.5% by weight of a chestnut shell extract, and 2-3.5% by weight of a aruncus sylvester root extract. According to the present invention, the plastic container is prepared through the processing ways of the multiple approaches, and has characteristics of smooth surface, good size stability, strong, efficient, broad-spectrum, long-lasting and safe antibacterial effect, effective prolonging of the shelf lives of various types of food, medicine and cosmetics and other items during the holding process, excellent aging resistance, good mechanical property, and long service life; and the far-infrared radiation effect can further provide effects of air refreshing, environment purification and odor eliminating so as to easily achieve environmental protection.

Description

technical field [0001] The invention relates to a plastic container, in particular to an antibacterial and aging-resistant plastic container and a preparation method thereof. Background technique [0002] Plastic containers are hollow blow-molded containers (such as plastic cups, barrels, feeding bottles, etc.), which are processed by hollow molding. It has the characteristics of light weight, no rust, not easy to break, corrosion resistance, beautiful shape and more economical, etc. It is widely used to replace glass, ceramics, and metal containers for holding solid, paste or liquid medicines, cosmetics, food and other substances. However, ordinary plastic containers are very sensitive to the environment, especially have poor resistance to heat aging and light aging. When used outdoors, they are easy to age, become brittle or pulverized, or even brittle, losing their use value. In addition, it does not have antibacterial properties, and it is very easy to infect and breed...
