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 pr

Embodiment 1
[0019] A kind of high-strength air filter paper of the present invention, this high-strength air filter paper is made up of following proportioning composition by weight: 50 parts of glass fiber, 5 parts of fiber binder, 8 parts of dispersant, 1 part of liquid binder , 6 parts of surfactant and 3 parts of crosslinking agent.
[0020] The liquid binder is sodium carboxymethylcellulose.
[0021] The fiber binder is one or more of viscose binders, polyester binders and tencel binders.
[0022] The surfactant is one or more of sulfate, sulfonate and phosphate.
[0023] The preparation process of described high strength air filter paper is as follows:
[0024] 1) Extract 50 parts of glass fiber and 5 parts of fiber binder according to the weight ratio and mix them evenly and add them to the beater;
[0025] 2) Add 8 parts of dispersant and 1 part of liquid binder to the beater in step 1, beat and disperse for 10-20 minutes;
[0026] 3) Add 6 parts of surfactant and 3 parts of c...
Embodiment 2
[0030] It differs from Example 1 in that the high-strength air filter paper is made up of the following parts by weight: 95 parts of glass fiber, 11 parts of fiber binder, 13 parts of dispersant, 5 parts of liquid binder, 9 parts of surfactant and 8 parts of crosslinking agent.
Embodiment 3
[0032] It differs from Example 1 in that the high-strength air filter paper is made up of the following parts by weight: 70 parts of glass fiber, 8 parts of fiber binder, 10 parts of dispersant, 3 parts of liquid binder, 7 parts of surfactant and 5 parts of crosslinking agent.

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...
