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 long-acting antimicrobial glass fiber air filtering paper and a preparation method thereof. The preparation method comprises the following steps: (1) preparing glass fibers; (2) pretreating the glass fibers; (3) preparing silver-loaded glass fibers; (4) coating porous graphene; (5) preparing silver / titanium dioxide-loaded antimicrobial glass fibers; (6) preparing the glass fiber filtering paper. By the method provided by the invention, the glass fibers are more effectively coated with graphene, silver and titanium dioxide in a uniform and dispersive manner, and the interaction area and the interface bonding strength of the glass fibers are further increased, so that the mechanical property of the glass fiber filtering paper is more excellent and the strength and the stiffness of the material are greatly improved; the composite material has an excellent antimicrobial property due to the antimicrobial characteristics of silver and titanium dioxide.

Description

technical field [0001] The invention relates to a durable 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 fi...
