Problems solved by technology

For example, the Chinese patent with publication number CN106400598A discloses a preparation method of water peanut enhanced air filter paper, which uses water peanut to enhance the filtration performance of filter paper; however, in the actual application process, the filtration efficiency is low, and most Harmful ingredients and impurities can still pass through the filter paper
[0004] In summary, the air filter paper of the prior art still cannot meet people's requirements for a high-quality air environment, and it is difficult to achieve the purpose of high-efficiency filtration.

preparation example Construction

[0045] The present invention also provides a method for preparing the air filter paper described in the above technical solution, comprising the following steps:

[0046] a) Mix the main glass fiber, molecular sieve activated powder and water, and perform beating for the first time in the presence of a dispersant to obtain the first slurry; simultaneously mix the wood pulp fiber with water, and perform the second beating to obtain the second slurry material; then the first slurry, the second slurry are mixed with water to obtain fiber cotton pulp;

[0047] b) molding the fiber cotton pulp obtained in step a) to obtain a wet paper base;

[0048] c) Sizing the wet paper base obtained in step b) with a binder, and drying to obtain air filter paper.

[0049] In the present invention, the main glass fiber, molecular sieve activated powder and water are firstly mixed, and the beating is performed for the first time in the presence of a dispersant to obtain the first slurry; at the ...

Embodiment 1

[0063] (1) Add 80kg of high-silica chopped glass fiber, 20kg of glass fiber cotton and 20kg of molecular sieve activation powder to the 1# beater machine with water added in advance to ensure that the fiber concentration is 1.6%. Turn on the beater and add 0.5 kg dispersant, beating for the first time until the fibers are evenly dispersed in water to obtain the first slurry.

[0064] (2) 10kg of wood pulp fibers are added separately to the 2# beater that added water in advance to ensure that the fiber concentration is 5%, and the beater is turned on for the second beating. Filamentized to obtain the second slurry.

[0065] (3) The first slurry obtained in step (1) and the second slurry obtained in step (2) are transported to the stock mixing tank, and clear water is continued to be added to keep the fiber concentration at 0.2%, so as to obtain fiber cotton pulp.

[0066] (4) Open the forming mesh belt, transport the fiber cotton pulp obtained in step (3) to the forming mesh b...

Embodiment 2

[0070] (1) Add 30kg of alkali-free chopped glass fiber, 50kg of medium-alkali chopped glass fiber, 20kg of glass fiber cotton and 15kg of molecular sieve activation powder into the 1# beater machine with water added in advance to ensure that the fiber concentration is 1.8%, and turn on Beater, add 0.6kg dispersant at the same time, perform the first beating until the fibers are evenly dispersed in water, and obtain the first slurry.

[0071] (2) 8kg wood pulp fiber is added separately in the 2# beater that adds water in advance, guarantees that fiber concentration is 4%, opens beater and carries out beating for the second time, and pulp beating degree 65 ° SR, guarantees that wood pulp fiber can Filamentized to obtain the second slurry.

[0072] (3) The first slurry obtained in step (1) and the second slurry obtained in step (2) are transported to the pulp mixing tank, and clear water is continued to be added to keep the fiber concentration at 0.1%, so as to obtain fiber cotto...

Abstract

The invention provides air filter paper, which is prepared from the following ingredients of 100 weight parts of body glass fiber, 10 to 20 weight parts of molecular sieve activation powder, 0.3 to 0.6 weight part of dispersing agents, 5 to 15 weight parts of wood pulp cellulose, and 5 to 15 weight parts of binding agents, wherein the body glass fiber consists of short cut continuous glass fiber and glass fiber cotton according to the mass ratio of (1 to 4):1. Compared with the prior art, the air filter paper provided by the invention uses the ingredients with the specific consumption; good mutual actions are achieved between all ingredients; the prepared air filter paper has good high-temperature-resistant performance, low wind resistance and high mechanical intensity; harmful particles can be effectively blocked; meanwhile, the whole filtering efficiency is high; in addition, acid gas such as hydrogen sulfide and carbon dioxide in the air can be efficiently filtered.

Description

technical field [0001] The invention relates to the technical field of filter materials, in particular to an air filter paper and a preparation method thereof. Background technique [0002] With the development of industry, harmful components in the air are increasing, and various particles and harmful components floating in the air pose a threat to optical electronics, LCD liquid crystal manufacturing, biomedicine, precision instruments, beverages and food, PCB printing and other industries. In order to solve the above technical problems, researchers installed high-efficiency filters at the air supply end of the air conditioner in the dust-free workshops of the above industries, which can reduce the occurrence of hazards to a certain extent. Among them, filter paper, as an important component of high-efficiency filters, has excellent performances such as low wind resistance, large dust holding capacity, and high filtration efficiency. [0003] At present, the pre-filter pa...
