Abstract

The invention discloses high-strength glass fiber air filter paper and a preparation method thereof. The air filter paper comprises glass fibers and an adhesive, wherein the glass fibers are randomly and uniformly distributed in a plane, micron-sized holes are formed among the plurality of glass fibers, and the adhesive is used for coating interlacing points among the glass fibers to form a net-shaped connecting surface; the glass fibers comprise short cut glass fibers with the diameters of 6 microns to 20 microns and/or glass cotton fibers with the diameters of 1 micron to 10 microns; the adhesive comprises inorganic silica gel, colloidal alumina or combination of the inorganic silica gel and the colloidal alumina. The air filter paper has the advantages of sufficient strength and excellent gas-liquid and liquid-liquid separation performance at normal and high temperatures and capability of resisting multi-time invasion and attack of wind speed and flow rate; in addition, the air filter paper can be used as a heat-insulated element or a heat-insulated filler in the fields of building, machinery, heat energy and the like, and also can be used as an air purification device.

Description

technical field [0001] The invention relates to a high-strength glass fiber air filter paper and a preparation method thereof. Background technique [0002] Glass fiber paper / felt has excellent flame retardant, sound-absorbing, and thermal insulation properties, and also has the advantages of light weight and low price. At present, glass fiber paper has been widely used in home decoration, energy-saving insulation of building exterior walls, air purification and other fields. Glass fiber air filter paper is a key component of the air filter element, and its thickness, weight, strength, stiffness and other properties determine the performance of the air filter. Glass fiber air filter paper is mainly used for air filtration in special environments, to block or trap the oil molecules diffused in the air through the air filter material, and to protect the space polluted by oil molecules. Since the filter is made of glass fiber air filter paper after discounting and machine fol...
