High-strength air filter paper and preparation method thereof

Abstract

The invention discloses high-strength air filter paper and a preparation method thereof. The high-strength air filter paper is prepared from, by weight, 50-95 parts of glass fibers, 5-11 parts of a fiber adhesive, 8-13 parts of a dispersing agent, 1-5 parts of a liquid-state binding agent, 6-9 parts of surfactants and 3-8 parts of a cross-linking agent. According to the high-strength air filter paper, the dispersing agent and the liquid-state binding agent are added when the high-strength air filter paper is prepared, therefore, the service life of the filter paper can be effectively prolonged, and the filtering effect is better; meanwhile, due to the fact that the sulfate, sulfonate and phosphate surfactants are added in the preparing process, the surface tension of the filter paper can be effectively decreased, the strength of the filter paper can be improved, the very good water and oil repellence can be achieved, the high-strength air filter paper adapts to various high-temperature rugged environments, and the service life of a filter is prolonged.

Description

technical field [0001] The invention relates to a high-strength air filter paper and a preparation method thereof. Background technique [0002] The air filter paper currently used in the market has a limited separation effect on greasy substances. Once the conventional air filter paper is used, the oil molecules will easily block the pores or adhere to the surface of the filter material, which will increase the resistance of the filter material and increase the energy consumption of the filter. At the same time, fungi are easy to breed in a damp environment, which will cause the protected environment to pass through the protective layer in a long-term high-pressure air volume and enter the protected environment, causing environmental pollution. In addition, due to the damp environment, the filter material is easy to be damp and its strength is reduced, which greatly reduces the service life of the air filter paper. [0003] With the continuous improvement of people's envi...
