Embodiment 1

[0029] The content of each component of a graphene biological diatom sponge is shown in Table 1. The preparation method of above-mentioned graphene biological diatom sponge, comprises the steps:

[0030] 1) After adding diatomaceous earth and graphene in the ball mill mixer, stir for 3h;

[0031] 2) After the diatomite and graphene in step 1) are ball milled and stirred, they are sent to a rotary kiln for roasting at a roasting temperature of 870° C. and a roasting time of 5 hours to remove organic matter and moisture;

[0032] 3) further ball milling and stirring the diatomite and graphene mixture after step 2) roasting in a ball mill mixer;

[0033] 4) Add the mixed powder of diatomite and graphene in step 2) to the mixing tank, then add polyether polyol and grafted polyether, and stir with a high-speed mixer at 8000 rpm for 30 min;

[0034] 5) After the stirring in step 4), add A-1 catalyst, A-33 catalyst and silicone oil L5810 and continue stirring for 10 minutes;

experiment example

[0040] One, in the graphene biological diatom sponge of the present invention, graphene content is to the influence test of sponge water absorption rate and water retention rate.

[0041] Choose 5 test sponges, namely:

[0042] 1. Ordinary sponge;

[0043] 2. Sponge with 60% diatom content;

[0044] 3. Diatom sponge with 1.0% graphene content;

[0045] 4. Diatom sponge with 3.0% graphene content;

[0046] 5. Diatom sponge with 5.0% graphene content;

[0047] Take 1g of 5 sponge samples from 5 kinds of sponges, respectively immerse them in glass containers filled with distilled water, let them stand at room temperature for 6 hours, take them out carefully, use filter paper to absorb the surface moisture, and weigh their masses.

[0048] Water absorption is calculated as follows: Q=(m 2 -m 1 ) / m 1 ×100%, where: m 1 , the initial weight of the sponge; m 2 , the weight of the sponge after absorbing water.

[0049] The above-mentioned sponge after absorbing water is put i...

Abstract

The invention relates to the technical field of sponges, and in particular relates to a graphene biological diatom sponge and a preparation method thereof. The sponge includes the following components: polyether polyol, grafted polyether, an A-1 catalyst, an A-33 catalyst, silicone oil, graphene, diatomite, stannum butylidene octoate and toluene diisocyanate. The graphene biological diatom spongeprovided by the invention adds the natural diatomite and the graphene to the components on the basis of an ordinary sponge, so that the naturalness and microporosity of the sponge are improved; and the sponge provided by the invention can release negative ions and far infrared rays, can adsorb and decompose bacteria and harmful gases entering the sponge body, can be further applied to air purification and water treatment, and has very high practical value.

Description

technical field [0001] The invention relates to the technical field of sponges, in particular to a graphene biological diatom sponge and a preparation method thereof. Background technique [0002] Sponge is a kind of porous material. Because of its high recovery elasticity and slow recovery elasticity, it is commonly used in sofas, mattresses, clothing, automobiles, cleaning products and filters, and has a wide range of uses. Graphene is the thinnest and hardest nano-material known in the world. It has extraordinary electrical conductivity, thermal conductivity, wave sensing, magnetic sensing, temperature sensing and light sensing properties at room temperature. In addition, graphene's unique adsorption affinity for organic matter and heavy metals is of great value to the water and sewage treatment industries. [0003] Biodiatom is a biogenic siliceous sedimentary rock whose chemical composition is SiO 2 Mainly, available SiO 2 ·nH 2 O means that the mineral composition ...
