A kind of high-strength air filter paper and preparation method thereof

Abstract

The invention discloses a high-strength air filter paper and a preparation method thereof. The high-strength air filter paper is composed of the following ingredients in parts by weight: 50-95 parts of glass fiber, 5-11 parts of fiber binder, and dispersant 8-13 parts, 1-5 parts of liquid binder, 6-9 parts of surfactant and 3-8 parts of crosslinking agent. The high-strength air filter paper of the present invention is prepared by adding a dispersant and a liquid binder, which can effectively prolong the service life of the filter paper and make the filtering effect better; at the same time, sulfate, sulfonate and phosphoric acid are added in the preparation process Salt surfactant can effectively reduce the surface tension of the filter paper, increase the strength of the filter paper, and can repel water and oil very well, adapt to various high temperature and harsh environments, and prolong the service life of the filter.

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...
