preparation example Construction

[0036]The preparation method of the phase change stabilization material is as follows: 1) heating and stirring butyl stearate and ultra-light aggregate in a vacuum kettle evenly, the mass ratio is 2:1, and the control temperature is 30°C; 2) Keep the pressure for 5 minutes under the negative pressure condition of 0.2Mpa, then gradually lower the temperature in the kettle to 0°C, and return to normal pressure; 3) cycle 3 times for temperature rise, pressure drop, temperature drop, and return to normal pressure in this way; 4) Control the characteristics after treatment Gently aggregate the material at a temperature of ≤10°C, and coat the surface with epoxy resin to obtain the phase change stabilization material.

[0037] The extra light aggregate is expanded perlite with a bulk density of 100kg / m 3 .

Embodiment 1

[0043] A kind of foam concrete composite lightweight partition wall slab, it is made of panel foam concrete 1 and core body foam concrete 2 (see figure 1 ), wherein the panel foam concrete 1 is symmetrically arranged on the left and right sides of the core foam concrete 2, and the thickness of the panel foam concrete 1 and the core foam concrete 2 is 3cm.

[0044] The mass percentage of each component in the panel foam concrete is: cement 47%, admixture 18%, ultra-light aggregate 8.83%, water 26%, fiber 0.03%, foam stabilizer 0.02%, water repellent 0.02% %, foaming agent 0.10%; the mass percentage of each component in the core foam concrete is: cement 35%, admixture 27%, phase change stabilization material 10.82%, water 27%, fiber 0.01%, foam stabilizer Agent 0.02%, foaming agent 0.15%.

Embodiment 2

[0052] A foam concrete composite lightweight partition wall slab, which is composed of panel foam concrete and core foam concrete, wherein the panel foam concrete is symmetrically arranged on the left and right sides of the core foam concrete, and the thickness of the panel foam concrete and the core foam concrete is equal. It is 4cm. Concrete mixing and pouring of foam concrete composite lightweight partition wall strips are carried out according to the mix ratio of panel foam concrete and core foam concrete described in Example 1.

[0053] According to "Foamed Concrete for Roof Thermal Insulation" (JC / T 2125-2012), the bulk density, compressive strength, water absorption, thermal conductivity and other properties of the face foam concrete slab and core foam concrete were tested, and the results are shown in Table 3 . According to "Lightweight Partition Wall Slats for Buildings" (GB / T 2451-2009), the foam concrete composite lightweight partition wall slats obtained in this e...

Abstract

The invention discloses a foam concrete composite lightweight partition batten, which comprises a panel foam concrete and a core foam concrete. The panel foam concrete is symmetrically arranged on both sides of the core foam concrete, and has the bulk density of 600-900kg / m<3>; and the core foam concrete has density of 150-500kg / m<3>. The present invention uses foam concrete layers with different densities and functions to design the composite lightweight partition batten, uses foam concrete with high density and high strength grade to substitute a traditional calcium silicate board panel structure, uses the core foam concrete with relatively low density and low strength to fill the middle of the composite wall. The method can effectively reduce the use of calcium silicate board, reduce the production cost of lightweight composite partition batten, and simplify the production process; and the obtained foam concrete composite lightweight partition batten has excellent performances of waterproofness, thermal insulation, fireproofness, sound insulation and phase change energy storage, and has broad application prospects.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a foam concrete composite lightweight partition wall strip and a preparation method thereof. Background technique [0002] Lightweight partition wall panels for construction in my country mainly include glass fiber reinforced cement panels, glass fiber reinforced gypsum panels, steel mesh reinforced cement panels, lightweight concrete panels, polystyrene particle sandwich lightweight panels, etc. Since the "Twelfth Five-Year Plan", the country has vigorously promoted green building materials and green wall materials, restricted the production of clay bricks and solid bricks, and made great progress in energy-saving and environmentally friendly lightweight partition wall slats. [0003] At present, the existing concrete foamed lightweight hollow partition wall slats have defects such as heavy weight, high cost, and poor sound insulation effect, which limit their popular...
