Embodiment 1

[0023] Such as figure 1 As shown, it is a schematic structural diagram of an energy-saving low-carbon thermal insulation composite wallboard. The energy-saving low-carbon thermal insulation composite wallboard consists of two panels 1 with a thickness of 4-8 mm and a thickness of 50-50 mm between the two panels 1. 150mm core plate 2, the panel 1 is a commercially available lignocellulose calcium silicate plate, which can be the NALC type plate produced by Aifuxi Company. The core board 2 is made of polystyrene foam plastic particles, fly ash, cement (>42.5 grade), sand (particle size<2mm), additives and water. The admixture is a mixture of Keny-J water reducer, Keny-F foaming agent and Keny-G adhesive. Keny-J water reducing agent, Keny-F foaming agent and Keny-G adhesive are produced by Guangzhou Hanhong Chemical Co., Ltd. and are available in the market.

[0024] The upper and lower ends of the core board 2 are provided with tongue and groove 3 . The double concave tenon a...

Embodiment 2

[0030] Similar to Example 1, the difference is that: Panel 1 uses a magnesia cement board with a thickness of 4-8 mm. The consumption of each raw material during production is: 6 parts by weight of polystyrene foam plastics, 60 parts by weight of fly ash, 250 parts by weight of cement, 60 parts by weight of sand, 0.3 parts by weight of Keny-J water reducing agent, and 0.3 parts by weight of Keny-F foaming agent 0.1 parts by weight, 6 parts by weight of Keny-G adhesive and 200-250 parts by weight of water.

[0031] The density of the obtained wallboard is ≤700kg / m 3 , Compression ≥ 3.5MPa, fire ≥ 3h, sound insulation ≥ 45DB. Thermal conductivity W / m k0.0969, hanging force ≥ 1000N, weather resistance, weather resistance 80 heat-rain cycle cycles, 5 heat-cold cycle cycles, no foaming, no peeling, impact strength of insulation system 3J .

Abstract

The invention provides an energy-saving, low-carbon and heat-insulation composite wallboard, and a production method and production equipment thereof. The energy-saving, low-carbon and heat-insulation composite wallboard is characterized by consisting of two surface boards and a core board arranged between the two surface boards, wherein the core board is prepared from polystyrene foamed plastics, fly ash, cement, sand, admixture and water. The invention also provides the production method and production equipment of the energy-saving, low-carbon and heat-insulation composite wallboard. The energy-saving, low-carbon and heat-insulation composite wallboard has the advantages of light weight, thin body, impact resistance, compression resistance, heat preservation, heat insulation, water proofing, fire proofing, sound insulation, shock proofing, explosion absorption, easy cutting, slotting, no need of plastering, fast dry operation, labor saving and the like.

Description

technical field [0001] The invention relates to an energy-saving and low-carbon thermal insulation composite wallboard, a production method and equipment thereof, and belongs to the technical field of thermal insulation composite wallboards. Background technique [0002] The current situation of external wall insulation in the country can basically be summarized into two major systems, the north and the south. Most of the northern regions adopt sandwich insulation composite exterior wall structure. This is a multi-layer material composite exterior wall, which is mainly made on-site by the inner surface layer, inner wall body, insulation core material, outer wall body and outer layer. Although it can achieve thermal insulation effect, it has the disadvantages of large thickness, low building use area, high one-time investment cost, complicated process, long construction period and heavy building structure, etc., which needs further improvement. Most of the southern regions ...
