Embodiment 1-6

[0035] Each raw material component of embodiment 1-6 carries out proportioning by weight in table 1:

[0036] Table 1

[0037]

[0038] In an embodiment, the foaming agent is composed of 1% sodium lauryl sulfate, 0.25% FM-550 foam stabilizer and 98.75% water by mass fraction.

[0039] The rubber powder is composed of NSJF-5 gypsum bonding rubber powder, hemihydrate gypsum powder and heavy calcium powder with a weight ratio of 1.2:80:20.

[0040] Add raw materials other than bamboo charcoal fiber into a stirring device and stir evenly to obtain gypsum slurry, then put the obtained gypsum slurry into a mixing bucket, and then take the diameter of 10-20 μm according to the parts by weight in Table 1, and the length of 5- The 20mm bamboo charcoal fiber is sprayed into the mixing tank by a spraying device, and at the same time, the gypsum slurry in the mixing tank is stirred to make the bamboo charcoal fiber evenly distributed, thereby preparing the pouring slurry.

Embodiment 7-11

[0050] According to the proportioning by weight of each raw material component in Table 3, the bamboo charcoal fiber gypsum board was prepared according to the technique of Example 1.

[0051] table 3

[0052]

[0053] Table 4 characterizes the results of Examples 3, 7-11 from the flexural strength of bamboo charcoal fiber gypsum board of the present invention, compressive strength, free formaldehyde removal rate, ammonia removal rate, release of negative ions and far-infrared radiation rate above 6 indicators . It can be clearly seen that the specific combination of BKS-101 polycarboxylate superplasticizer, citric acid and silicon carbide powder is used in Example 3, and the performance of the gypsum board produced is optimal.

[0054] It can be seen from Example 3, Example 7, Example 10, and Example 11 that when the water reducer is ASD-2 aliphatic high-efficiency water reducer, silicon carbide powder or fly ash is used as the dispersant for gypsum board The 6 indicator...

Abstract

The invention belongs to the field of building materials and relates to a bamboo carbon fiber gypsum board. The bamboo carbon fiber gypsum board is prepared from the following raw materials: gypsum powder, bamboo carbon fibers, a water reducing agent, a retarder, water, a foaming agent, rubber powder and a dispersant. The invention further relates to a preparation method of the bamboo carbon fiber gypsum board. The prepared bamboo carbon fiber gypsum board has the characteristics of relatively good adsorption capability and negative ion emission capability, relatively good thermal effect, relatively low cost and the like, and is very high in practical strength.

Description

technical field [0001] The invention belongs to the field of building materials, in particular to a bamboo charcoal fiber gypsum board and a preparation method thereof. Background technique [0002] Gypsum board is a material made of building gypsum as the main raw material. It is a building material with light weight, high strength, thin thickness, convenient processing, sound insulation, heat insulation and fire resistance. It is one of the new lightweight panels that are currently being developed. Gypsum boards have been widely used in interior partition walls, wall cladding panels (replacing plastering layers), ceilings, sound-absorbing panels, ground floor panels and various Decorative panels, etc. At present, the gypsum boards on the market mainly include paper gypsum boards, decorative gypsum boards, and gypsum hollow strips. However, these types of gypsum boards have problems of poor firmness and practical strength. [0003] Fiber gypsum board is a new type of bu...
