Air filter screen with nano-antibacterial and deodorization effects and manufacturing method thereof

Abstract

The invention relates to an air filter screen with nano-antibacterial and deodorization effects and a manufacturing method thereof. The manufacturing method comprises the following steps: making zinc oxide nano particles and silver nano particles into plastic masterbatches, mixing the plastic masterbatches into a plasticizing raw material, carrying out melting extrusion and drawnwork procedures to obtain a fully drawn yarn containing the zinc oxide nano particles and the silver nano particles, and then cropping the full-drawn yarn into short fiber; mixing mineral powder capable of generating anions or a metal oxide with radiativity into rubber paste, and coating the rubber paste on the surface of a filter screen fabric; and finally planting the short fiber on the surface of the filter screen fabric by an electrostatic flocking technology, and then forming a dense filtering layer when the short fiber is adhered to the surface of the filter screen fabric after the rubber paste is dried to obtain the filter screen. The air filter screen can filter out impurities, dirt and dust in air via meshes, release the anions, and realize degradation of organic matters such as bacteria, virus, mould and the like, thus achieving superexcellent antibacterial and sterilizing effects.

Description

technical field [0001] The present invention relates to an air filter screen with nano anti-bacteria and deodorizing effects and its manufacturing method, especially to a method that can make the surface of the air filter screen radiate α-rays, β-rays, γ-rays or X-rays. Or the way of losing electrons, releasing electrons into the air to continuously release negative ions, and can stimulate the short fibers planted on the surface of the air filter to produce auxiliary photocatalysts and catalytic effects respectively, so as to achieve anti-bacteria, viruses and molds and other organic substances A degraded air filter and a method for making the same. Background technique [0002] According to statistics, in metropolises, people spend about 80% to 90% of their time living in indoor environments (including: homes, offices or other buildings), and the quality of indoor air will directly affect people's quality of life. Therefore, the impact of indoor air pollutants on people's ...

Problems solved by technology

[0003] Generally speaking, the main function of the air filter used in today's air conditioning and ventilation systems is to filter out suspended particles in the air. These suspended particles will have different effects on the respiratory tract according to their particle size. Generally, the particle size is smaller than or Particles equal to 10 μm are called respiratory particles, because these particles will enter the respiratory system with respiration, and are deposited in the nasal cavity, respiratory tract and alveolar cells according to their particle size from large to small, while respiratory suspended particles in the indoor environment The sources include smoking, cooking, asbestos in building materials, man-made mineral fibers, plant pollen, animal allergens, microbial bacteria, molds and viruses, etc., which cause different forms of harm to the human body according to their nature. The microorganisms are the smallest among the above-mentioned suspended particles, and various types of microorganisms such as bacteria, molds and viruses are ubiquitous in nature, and the harm to the human body is not only the fastest but also the most obvious, such as: causing allergies , infection, toxic reaction, and even fatal to the human body, however, the air filter used in today's air conditioning ventilation system is helpless and cannot effectively filter out these microorganisms in the air

In view of this, in recent years, the designers and manufacturers of air-conditioning and ventilation systems have designed various electronic mechanisms with sterilization functions (such as: electronic mechanisms with ultraviolet light sterilization functions or electronic mechanisms that can produce photocatalyst sterilization functions) into air conditioners. In the ventilation system, however, these advanced air-conditioning and ventilation systems have not been popularized in ordinary homes and public places due to their high cost and large space occupation. Therefore, for the majority of users who use traditional air-conditioning and ventilation systems, the air in the The serious threat posed by microorganisms to human health has not been effectively addressed so far

[0004] In addition, in recent years, due to the increasing popularity of electronic and electrical products, the urban living space is too dense and closed, and the ion balance of the urban environment has been seriously damaged. Negative ions in the environment, various negative ion generators and related products have emerged as the times require, and are gradually favored by people. However, purchasing negative ion-related products will not only cause additional expenditure burdens on people, but also society as a whole will suffer from many derivatives. The use of electrical products has caused a heavy burden on the consumption of power resources, forming another type of environmental protection problem
