Example Embodiment

[0021] Example 1

[0022] Add the glass fiber to the beating machine for dispersion, and use water as the dispersant and solvent to dissociate the glass wool fiber raw material into cotton pulp;

[0023] The cotton pulp and white water solution are transported to the mixing tank for stirring and slag removal. The solid content in the slurry is controlled at 0.2% (weight), the viscosity is controlled at 8CP, the pH is controlled at 8, and the air content is controlled at 8%;

[0024] The uniformly stirred mixed slurry is transported to the filter screen of the twin-wire squeezer for papermaking, the thickness is controlled between 0.5mm, and the paperwork is vacuum suctioned to remove water and pressed to obtain a paper blank;

[0025] Dilute the adhesive to 20 times, evenly spray or overflow it on the glass fiber paper blank, the excess adhesive is sucked by the suction box, separated by the separator tank, and returned to the recycling tank;

[0026] The glass fiber paper blank after ...

Abstract

The invention discloses a high-strength glass fiber-made air-filter paper and a preparation method thereof. The high-strength glass fiber-made air-filter paper comprises glass fibers and a binder. The glass fibers are randomly distributed in a plane, micron-sized gaps are formed between the multiple glass fibers, and the binder coats interlacing points of the glass fibers so that a netted junction surface is formed. The glass fibers comprise chopped glass fibers having the diameter of 6-20 microns and/or glass wool fibers having the diameter of 1-10 microns. The binder comprises inorganic silica gel or/and colloidal-state alumina. The high-strength glass fiber-made air-filter paper has enough strength and excellent gas-liquid separation and liquid-liquid separation capability at a normal temperature and a high temperature, and can resist multitime influence produced by air speed and flow. The high-strength glass fiber-made air-filter paper can be used as a heat insulating element or a heat insulating filler in the fields of buildings, machinery and heat energy and can also be used for an air cleaning 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...
