Figure 3 It shows a front view of the structure of the inorganic composite thermal insulation core material in the embodiment of the utility model; Figure 4 The structure cross-sectional view of the inorganic composite thermal insulation core material in the embodiment of the utility model is shown. Figure 5 The utility model embodiment is shown in the attached Figure 4 The enlarged schematic diagram of the structure at A of the embodiment of the present invention shows that the inorganic composite thermal insulation core material comprises: a thin cement-based surface layer 1, a plurality of inorganic thermal insulation blocks 2 and a plurality of reinforcing ribs 3. A three-dimensional thin shell structure is formed based on the plurality of reinforcing ribs 3. The thin cement-based surface layer 1 covers the surface of the three-dimensional thin shell structure. A receiving space is provided in the three-dimensional thin shell structure. The plurality of inorganic thermal insulation blocks 2 are filled in the receiving space. The thin cement-based surface layer 1 is used to fix the three-dimensional thin shell and the inorganic thermal insulation blocks 2. The plurality of inorganic thermal insulation blocks 2 are filled in the three-dimensional thin shell. The three-dimensional thin shell and the inorganic thermal insulation blocks 2 are encapsulated based on the thin cement-based surface layer 1, so as to improve the appearance of the inorganic composite thermal insulation core material and improve the structural stability of the inorganic composite thermal insulation core material.

[0025] Specifically, the thickness of the thin cement-based surface layer 1 is h1, and the value range of h1 is: 3mm≤h1≤10mm, so that the thin cement-based surface layer 1 can meet the packaging stability requirements of the inorganic composite thermal insulation core material, while limiting the thickness of the thin cement layer to avoid the inorganic composite thermal insulation core material being too heavy and affecting the structural stability of the inorganic composite thermal insulation core material.

[0026] Furthermore, the thin cement-based surface layer 1 is a cement-based waterproof material, which is formed by mixing cement, fine sand, wood fiber, admixtures, additives and organic fiber, and has the characteristics of being waterproof, low shrinkage, good bonding performance and good toughness.

[0027] In this embodiment, the thin cement-based surface layer is prepared according to the mixing ratio of 80-120 kg of cement, 800-820 kg of fine sand, 1 kg of wood cellulose, 60-80 kg of admixture, 10-20 kg of additives, and 0.5 kg of organic fiber.

[0028] Among them, the additive is hydroxypropyl methyl cellulose ether, and the viscosity is not less than 100,000 mPa.s. Based on the hydroxypropyl methyl cellulose ether, the viscosity of the thin cement-based surface layer 1 can be effectively improved; the admixture is fly ash and silica ash, and the fly ash and the silica ash are configured in a 1:1 ratio, and the organic fiber is alkali-resistant glass fiber or polypropylene fiber, which can improve the toughness of the thin cement-based surface layer 1.

[0029] Specifically, the plurality of reinforcing ribs 3 are spliced ​​to form a three-dimensional thin shell, the three-dimensional thin shell is placed in a preset mold, and a plurality of inorganic thermal insulation blocks 2 are filled in the three-dimensional thin shell so that the plurality of inorganic thermal insulation blocks 2 can fit in the three-dimensional thin shell, cement is poured in the mold, and the thin cement-based surface layer 1 is formed on the surface of the three-dimensional thin shell and the plurality of inorganic thermal insulation blocks 2 based on the reserved gap in the mold. The thin cement-based surface layer 1 can be bonded to the surfaces of the inorganic thermal insulation blocks 2 and the three-dimensional thin shell. Based on the thin cement-based surface layer 1, the connection tightness between the inorganic thermal insulation blocks 2 and the three-dimensional thin shell can be improved, thereby improving the stability of the overall structure of the inorganic composite thermal insulation core material.

[0030] Specifically, the thickness of the reinforcing rib 3 is h2, and the value range of h2 is 10mm≤h2≤30mm. A spatial grid structure is formed by the reinforcing ribs 3 to limit the setting positions of the inorganic thermal insulation blocks 2 based on the three-dimensional thin shell.

[0031] Furthermore, based on the spatial grid structure, the overall stability of the composite core material can be improved, so that the inorganic composite thermal insulation core material has good bending load and hanging load, that is, the structural rigidity of the inorganic composite thermal insulation core material is improved, so as to improve the transportation safety and installation reliability of the inorganic composite thermal insulation core material.

[0032] Specifically, the inorganic thermal insulation block material 2 is foamed concrete, and closed foam pores are formed inside the foamed concrete to make the concrete lightweight and thermally insulated. The dry density of the inorganic thermal insulation block material 2 is m, and the value range of m is: 250kg / m 3 ≤m≤350kg / m 3 Through low-density foamed concrete, the overall mass and weight of the inorganic composite thermal insulation core material can be reduced, while the thermal conductivity of the inorganic thermal insulation block material 2 can be reduced, so that the inorganic thermal insulation block material 2 can have a good thermal insulation effect.

[0033] Furthermore, the heat transfer coefficient of the inorganic thermal insulation block material 2 is γ, and the value range of γ is: 0.07≤γ≤0.09. The inorganic thermal insulation block material 2 is formed by chemical foaming of low-density foam concrete, so that the inorganic thermal insulation block material 2 has a lower heat transfer coefficient, thereby reducing the risk of heat transfer loss and improving the thermal insulation effect of the inorganic composite thermal insulation core material.

[0034] Specifically, the width of the inorganic thermal insulation block 2 is w1, and the value range of w1 is: 30cm≤w1≤60cm, the length of the inorganic thermal insulation block 2 is d1, and the value range of d1 is: 60cm≤d1≤120cm, the thickness of the inorganic thermal insulation block 2 is h3, and the value range of h3 is 5cm≤h3≤20cm. Based on the fact that several inorganic thermal insulation blocks 2 are embedded in the three-dimensional thin shell, the size of the inorganic thermal insulation block 2 is adjusted according to the spatial layout in the three-dimensional thin shell, so that several inorganic thermal insulation blocks 2 can be spliced ​​and filled in the three-dimensional thin shell. By having each inorganic thermal insulation block 2 with a certain volume, the convenience of splicing the several inorganic thermal insulation blocks 2 in the three-dimensional thin shell is improved.

[0035] Specifically, a fiber mesh cloth 4 may be provided on the thin cement-based surface layer 1. The fiber mesh cloth 4 may improve the tensile strength of the thin cement-based surface layer 1, so that the inorganic composite thermal insulation core material has good structural stability.

[0036] Furthermore, a thin layer of cement can be coated on the surface of the combination of the three-dimensional thin shell and the plurality of inorganic thermal insulation blocks 2, and the cement insulation layer can be initially solidified by being left to stand, and the fiber mesh cloth 4 can be covered on the surface of the initially solidified cement thin layer, and cement can be coated on the surface of the fiber mesh cloth 4 to form the thin cement-based surface layer 1 with a certain thickness.

[0037] Based on the operation of secondary cement coating, the fiber mesh cloth 4 is added into the thin cement-based surface layer 1 so that the fiber mesh cloth 4 and the thin cement-based surface layer 1 form an integrally formed structure, and the tensile strength of the thin cement-based surface layer 1 is improved based on the fiber mesh cloth 4.

[0038] The utility model provides an inorganic composite thermal insulation core material, which is composed of a three-dimensional thin shell through a plurality of reinforcing ribs 3, a plurality of inorganic thermal insulation blocks 2 are filled in the three-dimensional thin shell, and a thin cement-based surface layer 1 is formed on the surface of the three-dimensional thin shell. The inorganic thermal insulation blocks 2 are used to improve the fire resistance of the thermal insulation core material, and the use safety of the thermal insulation core material is improved. At the same time, the reinforcing ribs 3 and the thin cement-based surface layer 1 are used to improve the structural rigidity of the thermal insulation core material, and the installation and use reliability of the thermal insulation core material are improved.
