Problems solved by technology

First, the smog phenomenon causes a large number of harmful substances such as tiny particles or droplets to exist in the air. Once inhaled, it will irritate and destroy the mucous membrane of the respiratory tract, causing serious damage to the nasal cavity, oral cavity, and lungs.
Second, smog leads to reduced outdoor visibility, traffic jams and frequent accidents
In particular, the main place for urban crowd activities is indoors, and windows are the main tool for realizing indoor and outdoor air exchange, and are also the main method for isolating indoor and outdoor harmful pollutants. It can achieve the maximum air permeability, but it cannot effectively block the dust and harmful particles in the air. Therefore, it is an important issue to improve indoor air quality to develop a screen window that can prevent harmful liquid droplets and dust particles from entering the room.
Chinese patent 201510266159.2 discloses a nano anti-fog screen, but its disadvantage is the use of nanofibers. Due to the disordered structure and low mechanical properties of nanofibers, the comprehensive effect of anti-fog screens is not ideal.
[0005] Activated carbon fiber is a highly absorbent carbon fiber filament with extensive microporous structure. The use of activated carbon fiber to prepare various adsorption products has become the mainstream to ensure the air environment. However, there is currently no activated carbon fiber compatible with other materials to form an anti Screen window with good smog effect and good mechanical properties

Abstract

The invention discloses an anti-haze carbon fiber window screen and a method for manufacturing the same, and particularly relates to a haze adsorption window screen with organic fiber non-woven fabric layers and activated carbon fiber adsorption layers which are overlapped with one another and a method for manufacturing the haze adsorption window screen. The anti-haze carbon fiber window screen comprises organic fiber non-woven fabric layers, two side metal fiber gridding cloth layers and a middle activated carbon fiber felt filter and adsorption layer. The organic fiber non-woven fabric layers are arranged on an indoor surface and an outdoor surface. The method includes melting organic fiber non-woven fabrics and adhering the organic fiber non-woven fabrics with one another, integrating the non-woven fabric layers, the metal gridding cloth layers and the activated carbon fiber felt filter and adsorption layer with one another by the aid of a symmetric overlapped structure in a thermal press fit mode; integrally assembling two sides of the surface of the integral structure and a window frame with one another by the aid of magnetic suction strips. The anti-haze carbon fiber window screen and the method have the advantages that the anti-haze carbon fiber window screen and the window frame are assembled by the aid of the magnetic suction strips, and accordingly the anti-haze carbon fiber window screen is flexible in detachment and replacement on the basis that the optimal haze air adsorption and purification are guaranteed.

Description

technical field [0001] The invention relates to a screen window, in particular to a carbon fiber anti-fog screen window and a preparation method thereof. Background technique [0002] With the rapid development of urban industrialization, the environment of large and medium-sized cities is facing increasingly severe challenges. In particular, the frequency of smog in my country has increased significantly, accounting for 30%-50% of the number of days in a year. Haze is a combination product of fog and haze, in which fog is an aerosol system composed of a large number of tiny water droplets or ice crystals suspended in the air near the ground; haze is composed of dust, sulfuric acid, nitric acid, organic hydrocarbons in the air composed of particles. The coexistence of the mixture of fog and haze seriously reduces the transparency of the air and seriously affects people's normal life and health. [0003] Haze weather has caused serious harm to human health. First, the smog...
