Embodiment 1
[0029] 1. Raw material preparation:
[0030] ① Preparation of loess powder: collect a certain weight of loess, crush it through an 80-mesh sieve, add deionized water 9 times the weight of loess, and then add a sodium hydroxide solution with a concentration of 1 to 25 wt% for mixing and pulping to control the pH value of the slurry 8.5, after stirring and reacting for 7 hours, add an appropriate amount of acetic acid to adjust the pH value to be neutral, continue stirring and reacting for 6 hours, filter, wash the filter cake with deionized water for 3 times, bake at 300°C for 1.5 hours, and grind through a 1200-mesh sieve to obtain white loess powder;
[0031] ②Preparation of Chinese toon leaves, persimmon leaves, and betel leaf extracts: collect non-rotten Chinese toon leaves, persimmon leaves, and betel leaf extracts, wash them separately, dry them naturally, crush them into 25-mesh coarse powder, and then pour them into the corresponding extracts. In the lifting tank, add ...

[0039] 1. Raw material preparation:
[0040] ① Preparation of loess powder: collect a certain weight of loess, crush it through an 80-mesh sieve, add deionized water 12 times the weight of loess, and then add a sodium hydroxide solution with a concentration of 1 to 25 wt% for mixing and pulping to control the pH value of the slurry 7.5, after stirring and reacting for 10 hours, add an appropriate amount of acetic acid to adjust the pH value to be neutral, continue stirring and reacting for 9 hours, filter, wash the filter cake with deionized water for 3 times, bake at 200°C for 3 hours, and grind through a 1200-mesh sieve to obtain white loess powder;
[0041] ②Preparation of Chinese toon leaves, persimmon leaves, and betel leaf extracts: collect non-rotten Chinese toon leaves, persimmon leaves, and betel leaf extracts, wash them separately, dry them naturally, crush them into 35-mesh coarse powder, and then pour them into the corresponding extracts. In the lifting tank, add ...

Abstract
The invention provides an antibacterial health-care plastic spectacles frame and a manufacturing method thereof. The plastic spectacles frame comprises, by weight, 75-95% of polymer, 3%-19% of natural antibacterial agents, 1.2%-3.5% of blueberry seed oil and 0.8%-2.5% of coupling agents. The natural antibacterial agents are made from, by weight, 70%-90% of loess powder, 5%-15% of cedrela sinensis leaf extracts, 2%-5% of persimmon leaf extracts and 3%-10% of betel pepper leaf extracts. In this way, the plastic spectacles frame manufactured through multiple machining means is stable in size, smooth in touch, high in tenacity, resistant to impact, resistant to stain, resistant to wear and good in rebound resilience; in the wearing process, the antibacterial and sterilization functions are achieved while fragrance and health-care ingredients can be released slowly so as to relieve or avoid eye fatigue and prevent shortsightedness and farsightedness; excellent aging resistance ability and better mechanical property are further achieved, and the service life is longer; the microenvironment around eyes can be improved through the far infrared radiation effect, and eye diseases can be prevented and treated.
Description
technical field [0001] The invention relates to a plastic spectacle frame, in particular to an antibacterial health-care plastic spectacle frame and a preparation method thereof. Background technique [0002] Spectacle frames generally include spectacle frames and spectacle legs. At present, the more common spectacle frames on the market are metal spectacle frames or plastic spectacle frames. Ordinary metal spectacle frames have a single color and are relatively bulky. Long-term wearing will oppress the bridge of the nose and cause discomfort. Moreover, ordinary metal spectacle frames generally need electroplating, which not only pollutes the environment, but also easily causes skin allergies, which is not conducive to health. High-grade metal spectacle frames such as titanium spectacle frames are expensive, although they are made of excellent materials. In contrast, plastic spectacle frames have the characteristics of strong toughness, high elasticity, impact resistance a...
