Abstract

Light and high-strength glass fiber filter paper is prepared from double-component hollow glass fibers and an adhesive and is characterized in that the double-component hollow glass fibers have the hollow rate being 0.60-0.95, the average diameter being 0.8-7.2 mu m and the length-diameter ratio being 16-78, the section is one or a mixture of round and oval, the double-component hollow glass fibers are formed by melting two glass raw materials in two kilns to form a mixed liquid and performing blowing with high-temperature flames at 1,450-1,550 and drawing. The invention further discloses a preparation method of the light and high-strength glass fiber filter paper. The preparation method comprises steps as follows: (1) dispersion with a beater; (2) stirring and deslagging treatment; (3) papermaking, vacuum water removal and pressing to form ground paper; (4) adhesive spraying; (5) drying. The light and high-strength glass fiber filter paper has the benefits of (1) lightness and environment-friendliness; (2) high strength.

Description

technical field [0001] The invention belongs to the field of air filtration, and relates to an air filter paper, in particular to a light-weight high-strength glass fiber 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. ...
