Embodiment 1

[0013] This embodiment is formed by bonding a base material and a stone panel 1 , and the base material is formed by bonding an upper glass fiber mesh cloth layer 2 , a ceramsite concrete layer 3 and a lower glass fiber mesh cloth layer 4 . The upper glass fiber mesh cloth layer 2 and the lower glass fiber mesh cloth layer 4 are the same, the thickness of the glass fiber mesh cloth is 2-3 mm, and the glass fiber mesh cloth can be used after being purchased from the market. Stone panel 1 can adopt marble or granite. Marble or granite is bonded on the upper fiberglass mesh cloth layer 2 . The ceramsite concrete layer is composed of quick-drying cement, clay ceramsite and polyvinyl chloride foamed grains, adding appropriate amount of water and cement strengthening agent and solidifying at room temperature after stirring, wherein quick-drying cement, ceramsite and polyvinyl chloride The weight ratio of the foamed particles is: 1:0.60-0.74:0.018-0.022, and the particle diameter o...

Embodiment 2

[0017] In this embodiment, the thickness δ of the ceramsite concrete layer is 30 mm, the particle size of the polyvinyl chloride foamed particles is 2 mm, and the weight ratio of quick-drying cement, clay ceramsite, and polyvinyl chloride foamed particles is The formula is: 1:0.7:0.021, adding water 0.3 to 0.4 times the weight of quick-drying cement and cement strengthening agent 0.2-0.3 times the weight of quick-drying cement for stirring. Among the clay ceramsite, the 8mm size accounts for 75-85% of the total ceramsite weight, and the rest is 15mm size ceramsite. There are no strict requirements for the ratio of 8mm and 15mm specifications in ceramsite, as long as they are within their respective ranges. All the other are identical with embodiment 1.

Embodiment 3

[0020] In this embodiment, the thickness δ of the ceramsite concrete layer is 25 mm, the particle size of the polyvinyl chloride foamed particles is 2 mm, and the weight ratio of quick-drying cement, clay ceramsite, and polyvinyl chloride foamed particles is The formula is: 1:0.67:0.020, adding water 0.3 to 0.4 times the weight of quick-drying cement and cement strengthening agent 0.2-0.3 times the weight of quick-drying cement for stirring. Among the ceramsite, the 8mm size accounts for 65-75% of the total ceramsite weight, and the rest is 15mm size ceramsite. All the other are identical with embodiment 1.

Abstract

The invention discloses a composite board, which is formed by adhering a substrate and a wooden panel. The substrate is formed by bonding an upper fiberglass mesh fabric layer, a ceramsite concrete layer and a lower fiberglass mesh fabric layer, wherein the ceramsite concrete layer is formed by adding water and concrete stiffeners in quick-dry concrete, ceramsite and polyvinyl chloride foaming particles, stirring and condensing at the normal temperature, wherein the weight ratio of the quick-dry concrete, the ceramsite and the polyvinyl chloride foaming particles is 1:0.60-0.74:0.018-0.022; and the particle diameter of the polyvinyl chloride foaming particles is not more than 2.5mm. The composite board has the advantages of high intensity, fire prevention, insulation, weather resistance and light weight.

Description

technical field [0001] The invention relates to building materials, in particular to a composite board. Background technique [0002] There are many composite boards using marble or granite as the panel. For example, the utility model patent specification of Chinese Patent Publication No. CN2058379U discloses a natural stone-glass fiber reinforced plastic sandwich concrete composite board, which is bonded and combined by a certain thickness of natural stone board and sandwich concrete. The interlayer concrete can be made of FRP trapezoidal and wave-shaped hollow concrete. Another example is a kind of ultra-thin stone honeycomb panel disclosed in the utility model patent specification CN2480456Y of China Authorized Announcement No., which consists of a base plate, a honeycomb hollow panel, and a transition panel and is bonded by a composite substrate and a thickness of 5 mm. The surface material stone board is composed of composite bonding; the honeycomb hollow board is a ho...
