Embodiment 1

[0057] The vermiculite diatomite composite water-absorbing mat provided in this example is made of the following raw materials:

[0058] 40 parts of diatomite, 10 parts of expanded vermiculite, 15 parts of calcium hydroxide and 5 parts of wood pulp fiber.

[0059] The preparation method of this vermiculite diatomite composite water-absorbing foot pad comprises the following steps:

[0060] The wood pulp fiber and expanded vermiculite are prepared into paper pulp and vermiculite pulp by pulping process respectively; vermiculite pulp, diatomaceous earth and calcium hydroxide are added to the debonded pulp in turn, and pulping and pre-mixing are carried out; The pre-mixed slurry is subjected to plate making, billet joining, and stacking to obtain slabs, and the slabs are autoclaved and cured, and then demolded and dried to obtain the vermiculite diatomite composite water-absorbing mat.

Embodiment 2

[0062] The vermiculite diatomite composite water-absorbing mat provided in this example is made of the following raw materials:

[0063] 70 parts of diatomite, 25 parts of expanded vermiculite, 30 parts of calcium hydroxide and 20 parts of wood pulp fiber.

[0064] The preparation method of this vermiculite diatomite composite water-absorbing foot pad comprises the following steps:

[0065] Add the wood pulp fiber into the vertical pulper, add water to loosen it for 40 minutes; add water to the expanded vermiculite and grind it to make the particle size less than 0.75 mm, and make pulp to obtain vermiculite pulp; add it to the loosened pulp in turn Vermiculite slurry, diatomaceous earth (40 microns in particle size) and calcium hydroxide are used for refining and pre-mixing; the pre-mixed slurry is used for board making, the board length is 2.4 meters, and the board width is 1.2 meters. Stacking to obtain slabs, performing pre-maintenance on the stacked slabs, autoclaving and...

Embodiment 3

[0069] The vermiculite diatomite composite water-absorbing mat provided in this example is made of the following raw materials:

[0070] 50 parts of diatomite, 15 parts of expanded vermiculite, 15 parts of calcium hydroxide and 5 parts of wood pulp fiber.

[0071] The preparation method of this vermiculite diatomite composite water-absorbing foot pad comprises the following steps:

[0072] Add wood pulp fibers into a vertical pulper, add water to loosen and dissolve for 50 minutes; add water to grind expanded vermiculite to make the particle size 0.2-0.75 mm, and make pulp to obtain vermiculite pulp; loosen the pulp Add vermiculite slurry, diatomaceous earth (50 microns in particle size) and calcium hydroxide in sequence, and carry out refining and pre-mixing; prepare the pre-mixed slurry, the length of the board is 2.5 meters, and the width of the board is 1.3 meters. Blanks and stacking to obtain slabs, pre-maintaining the stacked slabs, autoclaving and curing the slabs, an...

Abstract

The invention provides a vermiculite-kieselguhr compounded water absorption foot pad and a preparing method thereof. The vermiculite-kieselguhr compounded water absorption foot pad is prepared from, by weight, 40-70 parts of kieselguhr, 10-25 parts of expanded vermiculite, 15-30 parts of calcium hydroxide and 5-20 parts of wood pulp fibers. The vermiculite-kieselguhr compounded water absorption foot pad has the advantages of being super-high in water absorbing capacity, quick in moisture discharging and drying performance, resistant to pest, corrosion and mould and the like, is of a firm and stable layer-net porous structure, and has the powerful adsorption purification performance, dust, particles, viruses, hazardous substances and peculiar smells floated in air can be absorbed and decomposed, and therefore the air purifying effect is achieved. According to the preparing method of the foot pad, the structure of the product prepared with the method is of an interconnecting and engaging structure like a spider web, countless micro holes are formed in the product, and compared with the raw material, the absorption effect of the product is enhanced, and the product has the advantages of being convenient, simple, easy to operate and the like, and is suitable for mass production and wide application.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a vermiculite diatomite composite water-absorbing mat and a preparation method thereof. Background technique [0002] In modern family life, knitted chemical fiber mats are often used at the door of the living room or bathroom. However, there are some safety hazards in this type of household appliances. For example, knitted chemical fiber bathroom floor mats are wet after use, and need to be dried after each use. They are prone to mold, mold, mites, and odors. They need to be washed and dried frequently. Even so, there will still be many invisible bacteria and germs. Need to be replaced frequently. A thick carpet under the coffee table is fashionable and beautiful, and it is very comfortable to put your feet on it, but it also brings hidden health concerns. Many people are used to eating by the coffee table. Once biscuit crumbs, juice, etc. fall on it, they will be...
