Abstract

The invention discloses an air filtration glass fiber cotton composite material of series F5-F9. The air filtration glass fiber cotton composite material comprises non-woven cloth and a glass fiber cotton layer combined on the surface of the non-woven cloth through an adhesive material, wherein the non-woven cloth is 0.05-0.1mm thick; the glass fiber cotton layer is 0.25-1.5 mm thick and consists of glass fiber cotton with the diameter of 0.75-1.25 microns; the adhesive material is acrylic resin. A method for preparing the composite material comprises the steps of mixing and smelting proper amount of zinc oxide, borax, white sand, potash feldspar powder, pure alkaline, calcite, potassium carbonate and barium carbonate, performing primary fiber forming and then dragging the fibers through high-temperature and high-speed air flow to obtain the glass fiber cotton; dispersing the glass fiber cotton on the surface of the non-woven cloth, spraying glue, and drying to obtain the product. The air filtration glass fiber cotton composite material disclosed by the invention is high in intensity and high in filtration performance and has wide application prospects; due to the preparation method, the performance of the air filtration glass fiber cotton composite material can be further guaranteed.

Description

technical field [0001] The invention belongs to the field of silicon-containing inorganic fibers, and relates to a glass fiber composite material and a preparation method thereof, in particular to an F5-F9 series air filter glass fiber cotton composite material and a preparation method thereof. Background technique [0002] Glass fiber air filter material uses glass fiber as the main raw material. It has the characteristics of wide application range and corrosion resistance. It is an ideal air filter material. Glass fiber air filter materials are divided into three series according to the filtration efficiency: ventilation (ASHRAE), medium and high efficiency (HEPA) and ultra-high efficiency (ULPA). Glass fiber filter paper for ventilation (ASHRAE) is mainly used in ordinary air conditioning systems, gas turbines and air compressors; glass fiber filter paper (HEPA) for medium and high-efficiency air filters is mainly used in 10,000 to 100,000 clean rooms or workbenches, nucl...
