Description

Technical Field

[0001] The invention relates to the technical field of building materials, and in particular to a steel wire grid composite insulation board and a preparation method thereof. Background Art

[0002] With the intensification of the global energy crisis and the improvement of environmental protection awareness, the construction industry has an increasingly urgent demand for thermal insulation materials. Especially under the promotion of energy conservation, emission reduction and green building concepts, high-efficiency thermal insulation materials have become the focus of market attention. Traditional thermal insulation materials, such as rock wool and glass wool, have certain thermal insulation effects, but they have disadvantages such as high density, complex installation and great impact on the environment. Lightweight thermal insulation materials such as polystyrene foam and polyurethane foam, although light in weight and good in thermal insulation performance, have low structural strength, are flammable, and are easily affected by the environment and age during long-term use, which reduces the thermal insulation effect and safety.

[0003] In addition, existing composite insulation panels often adopt a simple stacking method, such as directly sticking or fixing the insulation layer on the base wall. This method is not only difficult to construct, but also the bonding force between the insulation layer and the base wall is weak, which can easily cause the insulation layer to fall off, affecting the overall safety and service life of the building. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the defects of the above-mentioned technology and provide a steel wire grid composite insulation board and a preparation method thereof.

[0005] In order to solve the above technical problems, the technical solution provided by the present invention is a wire mesh composite insulation board, comprising a steel mesh, a polystyrene particle insulation board, a belly wire, and a concrete layer. The polystyrene particle insulation board is located between the steel mesh and the concrete layer, and one end of the belly wire passes through the concrete layer and the polystyrene particle insulation board in sequence, and is welded to the steel mesh.

[0006] Furthermore, the steel wire mesh is made of stainless steel or galvanized steel wire, and the belly wire is made of galvanized steel wire.

[0007] Furthermore, the compressive strength of the concrete layer is not less than 20 MPa.

[0008] Furthermore, the density of the polystyrene particle insulation board is 15-30 kg / m 3 .

[0009] Furthermore, the angle between the web and the upper surface of the polystyrene particle insulation board is 40-50 degrees.

[0010] Furthermore, according to the above-mentioned method for preparing the thermal insulation board, the following steps are included:

[0011] a) Lay polystyrene particle insulation board on the upper layer of the steel wire mesh;

[0012] b) inserting the belly wire obliquely into the polystyrene particle insulation board so that the bottom of the belly wire abuts against the steel wire mesh, and the angle between the belly wire and the upper surface of the polystyrene particle insulation board is 40-50 degrees;

[0013] c) welding the bottom end of the web to the steel wire mesh, while ensuring that the top of the web protrudes out of the polystyrene particle insulation board;

[0014] d) pouring a concrete layer on the side of the polystyrene particle insulation board away from the wire mesh to form a composite insulation structure.

[0015] The advantages of the present invention compared with the prior art are:

[0016] 1) Excellent thermal insulation performance: Polystyrene particle insulation board has good thermal insulation performance and can effectively reduce the energy consumption of buildings.

[0017] 2) High strength: The combination of concrete layer and wire mesh makes the insulation board have high strength and can withstand greater external pressure.

[0018] 3) Corrosion resistance: The material selection of stainless steel or galvanized steel wire and galvanized steel wire improves the corrosion resistance of the insulation board and extends its service life.

[0019] 4) Convenient construction: The preparation method is simple, easy to operate, and easy to promote and apply. BRIEF DESCRIPTION OF THE DRAWINGS
