Problems solved by technology

The smaller the fiber diameter of the air filter paper, the smaller the particle size for removing particles in the air, and the higher the filtration efficiency, but the greater the relative wind resistance, the slower the filtration speed, and the lower the dust holding capacity. Traditional single filter paper The filter effect is not good, it is easy to grow bacteria and mold, the mechanical strength and durability of the filter paper are not good, and it can no longer meet people's requirements for a high-quality air environment. Therefore, a composite and efficient air with high filtration efficiency and large dust holding capacity is required. filter

Embodiment 1

[0029] A preparation method of high-permeability and low-resistance air filter paper, comprising the following steps:

[0030] Step 1. Add polyvinyl acetate, N-octyl (meth)acrylamide, vinyl tert-carbonate and polyether polyol into the reactor in a weight ratio of 4:6:1:3 and heat to 74°C, while Purge with a gentle nitrogen flow and stir for 20 minutes at a stirring speed of 300r / min to obtain a reaction mixture, which is kept in a water bath at 55°C for later use;

[0031] Step 2. Send the waste paper to the pulper for disintegration, and then beat and deink the waste paper. The pulp after beating and deinking flows into the pulp tank to obtain the waste paper pulp stock solution. Add 6% of the stock solution weight to the waste paper pulp stock solution. viscose fiber, and stir with a stirring rod to prevent the fiber from settling, and obtain a mixed slurry for subsequent use;

[0032] Step 3, put the wood pulp fiber and straw pulp fiber into the mixer according to the weig...

Embodiment 2

[0045] A preparation method of high-permeability and low-resistance air filter paper, comprising the following steps:

[0046] Step 1. Add polyvinyl acetate, N-octyl (meth)acrylamide, vinyl tert-carbonate and polyether polyol into the reactor in a weight ratio of 4:6:1:3 and heat to 80°C, while Purge with a gentle nitrogen flow and stir for 30% minutes at a stirring speed of 400r / min to obtain a reaction mixture, which is kept in a water bath at 60°C for later use;

[0047] Step 2. Send the waste paper to the pulper for disintegration, and then beat and deink the waste paper. The pulp after beating and deinking flows into the pulp tank to obtain the waste paper pulp stock solution. Add 8% of the stock solution weight to the waste paper pulp stock solution. viscose fiber, and stir with a stirring rod to prevent the fiber from settling, and obtain a mixed slurry for subsequent use;

[0048] Step 3, put the wood pulp fiber and the straw pulp fiber into the mixer according to the...

Embodiment 3

[0063] A preparation method of high-permeability and low-resistance air filter paper, comprising the following steps:

[0064] Step 1. Add polyvinyl acetate, N-octyl (meth)acrylamide, vinyl tert-carbonate and polyether polyol into the reactor in a weight ratio of 4:6:1:3 and heat to 77°C, while Purge with a gentle nitrogen flow and stir for 25% minutes at a stirring speed of 350r / min to obtain a reaction mixture, which is kept in a water bath at 57°C for later use;

[0065] Step 2. Send the waste paper to the pulper for disintegration, and then beat and deink the waste paper. The pulp after beating and deinking flows into the pulp tank to obtain the waste paper pulp stock solution. Add 7% of the stock solution to the waste paper pulp stock solution. viscose fiber, and stir with a stirring rod to prevent the fiber from settling, and obtain a mixed slurry for subsequent use;

[0066] Step 3, put the wood pulp fiber and straw pulp fiber into the mixer according to the weight rat...

Abstract

The invention discloses a preparation method of high-transmittance low-resistance air filtering paper. The preparation method comprises the following steps: step 1, preparing a reaction mixture; step2, preparing a mixing slurry; step 3, preparing a mixing fiber slurry; step 4, preparing a mixing powder; step 5, preparing a mixing paste; step 6, preliminarily preparing a paper base; step 7, coating and drying the paper base to obtain the final environmentally friendly efficient high-transmittance low-resistance air filtering paper. The prepared high-transmittance low-resistance air filtering paper is better in air permeability and lower in airflow resistance, the filtering efficiency is excellent, the filtering paper has the flowery odor of the plant and has the functions of preventing mould, sterilizing, and effectively repelling mosquitos, meanwhile, the deformation resistance, the differential pressure resistance and the bursting strength of the filtering paper are better, in addition, a large quantity of waste is used, the cost is lowered, the environment is protected, the resource is saved, and the preparation method has a higher practical value and an excellent application prospect.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to a method for preparing high-permeability and low-resistance air filter paper. Background technique [0002] The air conditioner filter element is the most commonly used component in every vehicle. It filters the air outside the car and sends it into the car, which improves the air quality in the car. The air filter paper, as the main component of the air conditioner filter element, determines the high efficiency filter. filtration efficiency. The smaller the fiber diameter of the air filter paper, the smaller the particle size for removing particles in the air, and the higher the filtration efficiency, but the greater the relative wind resistance, the slower the filtration speed, and the lower the dust holding capacity. Traditional single filter paper The filter effect is not good, it is easy to grow bacteria and mold, the mechanical strength and durability of the filte...
