Problems solved by technology

[0002] At present, a large number of "aluminum silicate fiber materials" and "magnesite composite materials" are used in fireproof boards. Due to the production and use of products, fibers and halogens will be produced, which will cause damage to human health, and the existing problem is that the core Large plate volume, low strength, corroded steel plate, strong water absorption and difficult to bond with steel plate, high cost
The second and third grade diatomite raw materials are low value-added products. If the raw materials are not utilized, they will only be sold at a very low price or thrown away, resulting in waste.

Embodiment 1

[0015] The diatomite fireproof board consists of the following ingredients in parts by weight: 30 parts of tertiary diatomite, 50 parts of Portland cement, 5 parts of fly ash, 1 part of animal protein foaming agent, and 1 part of polyvinyl alcohol , 0.5 parts of NC-II type early strength agent, 0.5 parts of ACC foam stabilizer, and 1 part of polypropylene fiber.

[0016] The preparation method of the diatomite fire-proof board consists of the following steps: firstly add 6% polyvinyl alcohol aqueous solution into the mixer, start the machine, and then mix 200 mesh three-grade diatomite, Portland cement, pulverized coal Add ash, NC-II type early strength agent, insulation board foam stabilizer and polypropylene fiber into the mixer, stir for 2 minutes at 80 rpm at room temperature, add animal protein foaming agent with a foaming machine and continue stirring 2 minutes, until fully mixed into a paste; the material mixed into a paste is injected into a mold with a hopper to make ...

Embodiment 2

[0018] The diatomite fireproof board is composed of the following ingredients in parts by weight: 35 parts of secondary diatomite, 55 parts of sulphoaluminate cement, 5 parts of fly ash, 1.5 parts of vegetable protein foaming agent, and 1.5 parts of polyvinyl alcohol 1 part, 1 part of ACC accelerator, 1 part of cement foam stabilizer, 1.5 parts of carbon fiber.

[0019] The preparation method of the diatomite fireproof board consists of the following steps: first add 4% polyvinyl alcohol aqueous solution into the mixer, start the machine, and then mix 80-mesh second-grade diatomite, sulphoaluminate cement, pulverized coal Add ash, ACC quick-setting agent, cement foam stabilizer and carbon fiber into the mixer, stir for 3 minutes at 80 rpm at room temperature, add vegetable protein foaming agent with a foaming machine and continue stirring for 1 minute until fully mixed Uniformly form a paste; inject the material mixed into a paste into a mold with a hopper to make a diatomite ...

Embodiment 3

[0021] 33 parts of secondary diatomite in embodiment 2, 53 parts of sulphoaluminate cement, 5 parts of fly ash, 1.2 parts of synthetic foaming agent, 1.3 parts of polyvinyl alcohol, 0.8 part of ACC accelerator, cement foam stabilization 0.7 parts of agent, 1.2 parts of wood fiber. Others are identical with embodiment 2.

[0022] The preparation method of the diatomite fire-proof board is composed of the following steps: first, add 8% polyvinyl alcohol aqueous solution into the mixer, start the machine, and then mix 100 mesh second-grade diatomite, sulphoaluminate cement, powder Add coal ash, ACC quick-setting agent, cement foam stabilizer and wood fiber into the mixer, stir for 3 minutes at 80 rpm at room temperature, use a foaming machine to inject synthetic foaming agent and continue stirring for 1 minute until fully Mix evenly to form a paste; inject the material mixed into a paste into a mold with a hopper to make a diatomite fireproof board.

Abstract

The invention relates to a fireproof plate, in particular to a fireproof diatomite plate and a fabrication method thereof. The fireproof diatomite plate comprises the following components in parts by weight: 30-35 parts of diatomite, 50-55 parts of cement, 5 parts of fly ash, 1-1.5 parts of foaming agent, 1-1.5 parts of polyvinyl alcohol, 0.5-1 parts of early strength agent or accelerating agent, 0.5-1 parts of foam stabilizer, and 1-1.5 parts of anti-cracking fiber. The fireproof diatomite plate has the advantages and the effects that the disadvantages that a core plate of the original fireproof door is large in unit weight, low in strength and high in hydroscopicity, erodes a steel plate, and cannot be bonded with the steel plate easily are overcome, and the fireproof diatomite plate is an optimal filling material for a fireproof door. The fireproof diatomite plate is green, environment-friendly, nontoxic, innocuous, fireproof, flame-retardant and smokeless, and does not erode the steel plate.
