Antibacterial health-care plastic spectacles frame and manufacturing method thereof

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...

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 range is narrow. It has poor compatibility with plastic raw materials, and there are problems such as uneven dispersion and easy agglomeration. Moreover, the antibacterial active ingredients are easy to precipitate during use, and the antibacterial effect cannot last
