Embodiment 1

[0022] (1) Mix 1,000g of ultra-high molecular weight polyethylene with a molecular weight of 3.5 million and 50g of glass fiber with a diameter of 0.2mm, and mix evenly after stirring at an ultra-high speed of 3,000r / min for 5 minutes, and then add 10g of di-tert-butyl hydroperoxide Mix and stir to obtain a mixture;

[0023] (2) Add 500g of activated carbon powder with a particle size of 100 mesh to the mixture obtained in step (1), stir evenly, and extrude it into the required shape at a high temperature of 200°C and a high pressure of 1000MPa.

[0024] In some places that only need to absorb particles in the air, only the product obtained in the above-mentioned Example 1 needs to be used.

Embodiment 2

[0026] (1) Mix 1,000g of ultra-high molecular weight polyethylene with a molecular weight of 3.5 million and 50g of glass fiber with a diameter of 0.2mm, and mix evenly after stirring at an ultra-high speed of 3,000r / min for 5 minutes, and then add 10g of di-tert-butyl hydroperoxide Mix and stir to obtain a mixture;

[0027] (2) Take 500g of activated carbon powder with a particle size of 100 mesh, add 1000g of H with a mass fraction of 1% 3 PO 4 In the aqueous solution, take it out after soaking for 12 hours, place it at a temperature of 80°C and heat it for 2 hours to obtain acid-loaded activated carbon powder;

[0028] (3) Add the acid-loaded activated carbon powder obtained in step (2) to the mixture obtained in step (1), stir evenly, and extrude it into the desired shape by high temperature of 200°C and high pressure of 1000MPa.

[0029] In some need to absorb heavy metals in the air, such as the compound of lead in the exhaust gas of automobiles etc.; ...

Embodiment 3

[0031] (1) Mix 1,000g of ultra-high molecular weight polyethylene with a molecular weight of 3.5 million and 50g of glass fiber with a diameter of 0.2mm, and mix evenly after stirring at an ultra-high speed of 3,000r / min for 5 minutes, and then add 10g of di-tert-butyl hydroperoxide Mix and stir to obtain a mixture;

[0032] (2) Take 500g of activated carbon powder with a particle size of 100 mesh, add 1000g of NaOH aqueous solution with a mass fraction of 1%, take it out after soaking for 12 hours, place it at a temperature of 80°C and heat it for 2 hours to obtain alkali-loaded activated carbon powder;

[0033] (3) Add the alkali-carrying activated carbon powder obtained in step (2) to the mixture obtained in step (1), stir evenly, and extrude it into the required shape by high temperature of 200°C and high pressure of 1000MPa.

[0034] In some acidic pollutant gases that need to be absorbed in the air, such as SO in automobile exhaust 2 , NO 2 Etc.; And th...

Abstract

The invention discloses an air purification material and a preparation method thereof. The air purification material has excellent adsorption performance on particles in the air, and at the same time has a good effect on eliminating automobile exhaust and bacteria in the air. The production difficulty is low, the output is high, and the purification effect is good. It has a good application prospect in outdoor air purification.

Description

technical field [0001] The invention relates to an air purification material and a preparation method thereof. Background technique [0002] In recent years, with the continuous development of industrialized cities, real estate development, large-scale emissions of automobile exhaust, etc., the haze weather has invaded the country on a large scale, and the air quality problem has become the focus of social attention. At the same time, the pollution problem of PM2. . [0003] People's activities in the haze weather will lead to health hazards; low visibility will lead to traffic accidents and so on. At present, the research of enterprises in our country is only on indoor air treatment, and there are many technical problems in the research and treatment of outdoor air. The existing purification materials for treating smog and haze air are difficult to produce, have low yields, and have poor purification effects. Generally, it can only filter pollutants in the air, such as b...
