Embodiment 1

[0019] Example 1 Take 1 part of polypropylene fine fiber, 20 parts of sulphoaluminate cement quick-setting agent, and 80 parts of silica fume and mix evenly to obtain the reinforcing agent. Take 2 parts of this reinforcing agent, 1.8 parts of saw foam, and quickly harden 25 parts of sulphoaluminate cement, 2 parts of fly ash, 30 parts of river sand, 15 parts of water, and 2 parts of cement softening agent are fully mixed, and the slurry is made after mixing evenly. The total amount of slurry poured on the plate , spread alkali-resistant mesh cloth after smoothing, and add slurry after flattening , spread alkali-resistant mesh cloth after smoothing, add the remaining slurry to smooth, calender after the initial setting of the slurry, cover the polyvinyl chloride film, form it after 24 hours, fully dry it after 7 days of shading and curing, the thickness of the slurry layer About 0.8cm-1cm.

Embodiment 2

[0020] Example 2 Take 1 part of polypropylene fine fiber, 30 parts of sulphoaluminate cement quick-setting agent, and 100 parts of silica fume and mix evenly to obtain the reinforcing agent. Take 5 parts of this reinforcing agent, 4 parts of saw foam, and quickly harden 33 parts of sulfoaluminate cement, 5 parts of fly ash, 50 parts of river sand, 23 parts of water, and 4 parts of cement softening agent are fully mixed. High, and the cost is not low.

Embodiment 3

[0021] Example 3 Take 1 part of polypropylene fine fiber, 25 parts of sulphoaluminate cement quick-setting agent, and 90 parts of silica fume and mix evenly to obtain the reinforcing agent. Take 3 parts of this reinforcing agent, 3 parts of saw foam, and quickly harden 30 parts of sulphoaluminate cement, 3 parts of fly ash, 45 parts of river sand, 20 parts of water, 3 parts of cement flexible agent are fully mixed, and preparation method is with embodiment 1, and this is the best embodiment, and embodiment 1 is identical The strength of this kind of wallboard is suitable, and the cost is also suitable.

[0022] The quick-hardening sulfoaluminate cement described in the present invention is a commercially available product, for example: 42.5,52.5 quick-hardening sulfoaluminate cements produced by Tangshan Liujiu Cement Co., Ltd.; polystyrene board is 15-18kg / m 3 Flame retardant type, the thickness is divided into 4cm and 7cm; fly ash is the coal ash collected from the power pla...

Abstract

The invention discloses a three-dimensional reinforced cement light wallboard with light weight, great strength, good heat insulation and good sound insulation. The wallboard comprises a polyphenyl board, a sizing agent layer and an alkali-resistant fiber grid, wherein the sizing agent layer is prepared from the following raw material components in part by weight: sawdust, rapid hardening sulphatealuminium cement, fly ash, river sand, reinforcing agent, water and cement softening agent, wherein the reinforcing agent consists of the following raw material components in part by weight: polypropylene fine fiber, sulphoaluminate cement accelerator and silica fume. The three-dimensional reinforced cement light wallboard has the advantages of reducing the dead weight of buildings, increasing the effective use area of the buildings, reducing the structural engineering cost for the buildings, protecting farmland, protecting finite land resources, realizing the factory production of walls, fully and reasonably utilizing industrial and agricultural waste and achieving the aims of protecting earth resources and preventing waste from polluting living environment.

Description

technical field [0001] The invention relates to a lightweight wallboard in the field of building materials, in particular to a three-dimensional reinforced cement lightweight wallboard with light weight, high strength, good thermal insulation and good sound insulation. Background technique [0002] Traditional clay bricks occupy a large amount of land, causing water and soil erosion, wasting a lot of fuel, and polluting the environment. Strengthening ecological construction and environmental protection is a basic national policy of our country. Therefore, vigorously developing and promoting, and applying new types of walls are not only the needs of the modernization of the construction industry , It is also the need for the coordinated development of the national economy, social environment and resources. For the block material wall, due to the low flexural strength, easy to collapse, and poor earthquake resistance, it will cause a large number of casualties when an earthqua...
