Problems solved by technology

At present, the air filter material of power plants requires a large amount of ventilation, which requires high strength and burst resistance for the filter material, and requires water and oil repellency to cope with harsh environments, thereby prolonging the service life of the filter. The existing The filter material needs to be further enhanced
Moreover, it has been reported that by adding nano-silver on the surface of glass fiber to endow glass fiber with antibacterial properties, it can be applied to filter paper and resin to make it have antibacterial properties; The specific parts of the surface cannot be evenly distributed on the surface, thereby affecting the antibacterial effect; on the other hand, nano-silver and glass fibers cannot be tightly combined (especially when the content of nano-silver particles increases, agglomeration is prone to occur), and it is easy to use during use. Falling off, thus affecting the service life and antibacterial effect

Abstract

The invention discloses antibacterial glass fiber air filter paper and a preparation method thereof, wherein the preparation method comprises the following steps: (1) preparation of glass fibers; (2) pretreatment of the glass fibers; (3) preparation of silver-supported glass fibers; (4) coating of porous graphene; (5) preparation of the silver / titanium dioxide supported glass fibers; and (6) preparation of the glass fiber filter paper. Through the method, graphene, silver and titanium dioxide can be more effectively and evenly dispersed and coated on the glass fibers, and the interaction area and interface binding force of the glass fibers are further increased, so that the mechanical properties of the glass fiber filter paper are more excellent, and the material strength and stiffness are greatly improved; and the composite material has excellent antibacterial properties due to antibacterial properties of silver and titanium dioxide.

Description

technical field [0001] The invention relates to an antibacterial glass fiber air filter paper and a preparation method thereof. Background technique [0002] my country is a big electricity consumer, with a total annual electricity consumption of 4,868.4 billion kwh, and an annual growth rate of 4-10%. However, the annual average output of my country's largest Three Gorges Hydropower Station is only 107.3 billion kwh, and the annual There are 289 large-scale power stations with an output of more than 5 million kilowatt-hours, and countless medium-sized and small-sized power stations. All power plants need to install multiple sets of air filters in the air intake and exhaust systems to provide clean air. . This type of air filter is divided into three grades of high, medium and primary efficiency according to the efficiency level. Except for the primary filter which uses metal wire or glass fiber felt, the filter material of the rest of the filters is basically glass fiber fil...
