Problems solved by technology

[0002] At present, with the continuous improvement of scientific and technological living standards and the neglect of environmental protection, the air quality in China and around the world continues to deteriorate, posing a serious threat to people's physical and mental health. At present, the main purification materials on the market include activated carbon purification materials and nano Mineral crystal purification materials, the above-mentioned purification materials are firstly poor in adsorption capacity, adsorption rate and adsorption capacity, and the repeated utilization rate is not high, and because activated carbon purification materials are powdery, nano-mineral crystals are mostly extremely small It is granular and requires a special container for storage, which makes it inconvenient to transport and use

Embodiment Construction

[0008] Below in conjunction with specific embodiment, the present invention is described in further detail: a kind of preparation method of the foam that is attached to purification material, comprises the steps:

[0009] 1) Add graphene to the solution of water and sodium silicate, and then carry out ultrasonic dispersion treatment. The final mixed solution was left standing, and the standing time was 2 to 6 hours to obtain a mixed solution A;

[0010] 2) Add diatomaceous earth, sepiolite powder, lithium carbonate, and oxalic acid into the stirring tank for stirring, wherein the stirring speed is 400-600 rpm, and the stirring time is 10-15 minutes to obtain a mixed solution B;

[0011] 3) Mix the mixed solution A and the mixed solution B, put them into a high-speed stirring tank for stirring, wherein the stirring speed is 2000~3000 rpm, and the stirring time is 1~2 hours, to obtain the mixed solution C, and carry out the mixed solution C Ultrasonic dispersion treatment, the ...

Abstract

The invention discloses a preparation method of foam with a purifying material adhered thereto. The preparation method includes: preparing a graphene dispersion solution and a diatomite-sepiolite purifier solution respectively; mixing the two solutions, performing ultrasonic dispersion, calcining, and grinding to obtain the powdery purifying material; processing the powdery purifying material into particles; mixing the particles with a foaming polymer and a foaming auxiliary in a foaming die for foaming, curing and forming to obtain blocky purifying foam with purifying effect. Graphene is organically combined with diatomite and sepiolite which have natural adsorption characteristics to obtain the purifying material having extremely high adsorption capability and adsorption rate, the purifying material is organically combined on soft polyurethane foam to obtain a purifying material block which is reusable and convenient to carry and cut, and the purifying material block can be widely applied in various existing purifying equipment and purifying masks and has great social benefit.

Description

technical field [0001] The invention relates to the technical field of purification materials, and more specifically, to a method for preparing foam with purification materials attached thereto. Background technique [0002] At present, with the continuous improvement of scientific and technological living standards and the neglect of environmental protection, the air quality in China and around the world continues to deteriorate, posing a serious threat to people's physical and mental health. At present, the main purification materials on the market include activated carbon purification materials and nano Mineral crystal purification materials, the above purification materials are first of all poor in adsorption capacity, adsorption rate and adsorption capacity, and the repeated utilization rate is not high, and because activated carbon purification materials are powdery, nano-mineral crystals are mostly extremely small It is granular and requires a special container for st...
