Abstract

The invention discloses a glass fiber-containing highly waterproof air filter paper. The glass fiber-containing highly waterproof air filter paper is made by using the following raw materials, by weight, 46-48 parts of a Bambusa textilis pulp, 52-54 parts of a mulberry bark pulp, 1-2 parts of dried oleander leaf, 0.7-0.9 parts of oleic acid, 0.4-0.5 parts of flaxseed gum, 0.3-0.5 parts of starch wheat, 3-4 parts of montmorillonite, 1-2 parts of cerium oxide, 1-2 parts of chopped glass fiber, 1-2 parts of molybdenum dioxide, 5-7 parts of polyamine epichlorohydrin resin, 3-5 parts of a vinyl acetate-acrylic emulsion, 0.3-0.4 parts of polyvinyl alcohol, 0.2-0.4 parts of a paraffin emulsion, 1-2 parts of an assistant and a proper amount of water. Cerium oxide added in the invention has a catalysis performance and can purify air; the addition of the chopped glass fiber improves the waterproof performance; and the assistant added in the invention is safe and environmentally-friendly, and forms tiny apertures on the surface of filter paper, so the adsorptivity is increased, and the filter paper has a waterproof property. The filter paper has the advantages of small filtering resistance, high efficiency, waterproof property, moisture resistance, and high wet stiffness.

Description
