[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0016] The purpose of this utility model is to provide a perlite shell thermosetting composite insulation board to solve the problems existing in the above-mentioned prior art, and solve the problems of ordinary thermosetting composite boards being prone to chipping, corner loss, and breakage. At the same time, the thermal conductivity coefficient and fire resistance level are also improved to a certain extent.

[0017] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0018] like Figures 1 to 2As shown, this embodiment provides a perlite shell thermosetting composite insulation board, including a thermosetting composite board 2. Preferably, the thermosetting composite board 2 is a homogeneous plate-shaped product made by compounding polystyrene foam particles or boards as the insulation matrix using a treatment agent. Its composite process mainly includes particle coating, mixed molding, or substrate infiltration. It has a certain shape retention ability under fire and does not produce molten dripping. Specifically, during the production process of the thermosetting composite board 2, it uses special inorganic non-combustible mineral fibers. The inorganic non-combustible mineral fibers are treated with composite polystyrene foam particles and other additives are added. After being mixed with water and evenly stirred, they are pressed into shape by a mold. The thermosetting composite panel 2 has an inner facade and an outer facade, and the inner facade and / or the outer facade are covered with a perlite mold shell 1. The perlite mold shell 1 has a layered structure and matches the structure of the inner and outer facades. By covering the inner facade and / or the outer facade of the thermosetting composite panel 2 with the perlite mold shell 1, the inner facade and / or the outer facade of the thermosetting composite panel 2 has a hard shell structure, which solves the problem of ordinary thermosetting composite panels 2 being prone to chipping, corner loss, and breakage.

[0019] As a preferred embodiment of the present invention, the perlite formwork 1 includes a base layer composed of crack-resistant mortar mixed with expanded perlite particles and sprayed onto a thermosetting composite panel 2. At least one grid structure is pressed into the base layer. The expanded perlite particles are white granular materials with a honeycomb structure, made by preheating perlite sand and then instantaneously calcining and expanding it at high temperature. The crack-resistant mortar is a polymer mortar with excellent deformation resistance and bonding properties, made primarily from high molecular weight polymers, cement, and sand. The fireproofing and high strength of the crack-resistant mortar enhance the fireproofing rating and strength (compressive and flexural strength) of the thermosetting composite panel 2. Furthermore, by adding a certain proportion of expanded perlite particles to the crack-resistant mortar, the weight of the entire perlite formwork 1 thermosetting composite insulation panel can be further controlled and its thermal conductivity reduced. During the preparation of the entire grid structure perlite formwork 1 thermosetting composite insulation board, anti-cracking mortar mixed with expanded perlite particles is sprayed on the inner and / or outer facades of the thermosetting composite board 2, and after being pressed into the grid structure and cured, a hard shell structure is formed, which can not only improve the strength of the entire perlite formwork 1 thermosetting composite insulation board, but also improve its fire resistance level and reduce its thermal conductivity.

[0020] As a preferred embodiment of the present invention, the grid structure is a glass fiber mesh cloth, which is easy to obtain materials, and on the other hand has good alkali resistance, flexibility and high tensile strength in the warp and weft directions, further enhancing the strength of the entire perlite formwork 1.

[0021] As a preferred embodiment of the present invention, the thickness of the perlite formwork 1 is 1 mm to 2 mm, so as to fully ensure the strength of the hard shell structure formed on the inner and / or outer facades of the thermosetting composite panel 2.

[0022] As a preferred embodiment of the present invention, the thickness of the thermosetting composite board 2 is 25 mm to 30 mm, so as to fully ensure the thermal insulation performance of the thermosetting composite board 2, thereby improving the thermal insulation performance of the entire perlite formwork 1 thermosetting composite insulation board.

[0023] The various performance indicators (density, volume water absorption, compressive strength, flexural strength, flexural strength, thermal conductivity and combustion performance) of the entire perlite shell 1 thermosetting composite insulation board are shown in Table 1:
