A kind of preparation method of air filter material

Abstract

The invention discloses a method for preparing an air filter material. The method includes pretreatment of fibers, preparation of hydrophobic fibers, preparation of modified attapulgite, and preparation and spraying of spraying raw materials; The surface of the polyester fiber is modified to destroy the structure of the polyester fiber, reduce the cohesion between the fibers, and increase the surface roughness and specific surface area of ​​the polyester fiber, thereby improving the adsorption capacity of the polyester fiber and making the polyester fiber It has good hydrophobicity, prevents polyester fibers from absorbing moisture and sticks together, and improves the filtering ability of modified polyester fibers; the present invention also combines activated carbon with attapulgite, which not only utilizes the adsorption performance of activated carbon to be stronger than that of attapulgite It also prevents a large number of activated carbon particles from contacting one by one to form a conductive circuit, which reduces the electrostatic adsorption capacity of polyester fibers, thereby improving the adsorption capacity of polyester fibers to particulate pollutants and odors in the air.

Description

technical field [0001] The invention belongs to the technical field of air filter devices, and in particular relates to a preparation method of an air filter material. Background technique [0002] Air is one of the important environments on which organisms live. With the development of society, environmental pollution problems have also been exposed. Among them, air pollution affects people's lives all the time, and people gradually pay attention to air pollution problems, which also gave birth to With the development of air filter devices, air filter devices can remove solid particulate matter in the air. Some air filter devices in the prior art also carry out photocatalytic substances on filter materials to kill bacteria, germs, etc. in the filtered air. kill, decompose. [0003] In the prior art, there are many types of materials used for air filtration.

Problems solved by technology

[0003] In the prior art, there are many types of materials used for air filtration. The main principles are mainly divided into intercepting particulate pollutants in the air by relying on physical properties and electrostatic adsorption. Among them, the material cost of the physical interception principle is low, and it is also an existing It is the most widely used material in technology, but in the existing technology, this type of material does not have a strong adsorption capacity for pollution particles during work. If the intercepted pollution particles are not disposed of in time, they will easily detach from the filter material after a large amount of accumulation. As a result, the filtering effect is poor, and the adsorption effect of this type of air filter material is more obviously affected by its own conditions. This type of air filter material is easy to absorb moisture in a humid environment, which causes the fibers of the filter material to bond together, thereby reducing Improve the filtering effect and improve the air resistance in the filtering process of the filter material, in order to solve this problem, the present invention provides the following technical solutions
