Example Embodiment

[0023] Put the spinning grade plastic resin masterbatch into a dryer at 70℃ for drying. The powdery plant-derived extract can pass through a sieve with a pore size of 0.065mm, and the active ingredient content should be greater than 25% of the weight of the extract. Add at 4% of the weight of the plastic resin masterbatch. After the mixture prepared by weight ratio is fully stirred evenly, it is put into the plastic extruder through preheating, melting, plasticizing, calculation, spinning, and then melting Extrude the monofilament at a temperature of 200°C, put it in a 35°C water tank for cooling, and put it into a tractor at 100°C for drawing and shaping. The preparation method of plant-derived powder is as follows. Weigh 90 grams of Chinese herbal medicine Solidago, 180 grams of lotus leaves, 120 grams of cloves, and 100 grams of star anise, crush them to 60 meshes, add an appropriate amount of 95% ethanol aqueous solution, and soak for 40 hours. Ultrasonic assisted extractio...

Abstract

The invention discloses a preparation method for a biological source-based air purifying and filtering screen. The preparation method comprises the steps of baking, blending, stirring, melting extrusion, cooling, drawing and setting of materials; powder prepared from Chinese herbal medicines including solidago decurrens, lotus leaves, syzygium aromaticum and illicium verum, with high sterilizing power and wide antibiotic spectrum, is added in the blending link, so that the filter screen produced by weaving monofilaments has better purifying and sterilizing effects after being proved by severe tests.

Description

technical field [0001] The invention relates to a filter net, in particular to a biological source-based air purification filter net and a preparation method thereof. technical background [0002] More and more studies have shown that air pollution has become a huge problem facing human beings, bringing direct or potential harm to people's work and life. The current air purification is mainly based on dust removal. Even if there is a sterilization device, it mainly uses ultraviolet disinfection or chemical disinfectant disinfection. However, no matter whether physical or chemical methods are used for disinfection, they will cause greater irritation and harm to the human body, and the bactericidal effect is limited. During years of production practice, the applicant has continuously researched and developed an environmentally friendly and green air purification device. Starting from the abundant resources of Chinese herbal medicines with good bactericidal effects, the applic...
