Description

Technical Field

[0001] The present invention relates to the technical field of thermal insulation boards, and in particular to a composite thermal insulation board and a manufacturing method thereof. Background Art

[0002] In the field of building materials, insulation board, as an important energy-saving material, is widely used in thermal insulation of building structures such as walls, roofs, and floors. Although traditional insulation board materials such as polystyrene boards and rock wool boards have certain insulation effects, they are insufficient in terms of strength, fire resistance, and ease of construction.

[0003] As new basic insulation materials, graphite polystyrene particles and polystyrene particles are gradually favored by the market due to their good insulation performance and environmental protection characteristics. However, the insulation boards made of these granular materials alone still need to be improved in terms of structural strength and durability.

[0004] In order to enhance the performance of insulation boards, people have begun to try to add various additives to insulation boards, such as flame retardants, reinforcing fibers and adhesives, to improve their fire resistance and structural strength. At the same time, by optimizing the production process, such as mixing, compacting and curing steps, the physical properties and processability of insulation boards can be further improved.

[0005] In order to improve the overall performance of the insulation board, people have also tried to composite a reinforcement layer on the surface of the insulation board. As a commonly used reinforcement material, glass fiber mesh cloth is widely used in composite reinforcement of insulation boards due to its high strength and good crack resistance. However, there are some problems with the existing composite process, such as the glass fiber mesh cloth is not tightly attached and easy to debond, which affects the overall performance and construction quality of the insulation board.

[0006] Therefore, a composite thermal insulation board and a manufacturing method thereof have become problems to be solved urgently. Summary of the invention

[0007] The technical problem to be solved by the present invention is to provide a composite insulation board and a method for making the same, using graphite polystyrene particles or polystyrene particles as the basic insulation material and compounding a 3mm thick glass fiber mesh cloth on the surface of the insulation board to improve the insulation performance, structural strength and durability of the insulation board.

[0008] In order to solve the above technical problems, the present invention provides a technical solution: a method for manufacturing a composite insulation board, comprising the following steps:

[0015] S7, perform maintenance again;

[0016] S8, cutting width and length dimensions;

[0017] S9. Packing.

[0018] Further, in step S1, graphite polystyrene particles or polystyrene particles are selected as the basic thermal insulation material, and flame retardants, reinforcing fibers, and binders are selected as additives;

[0019] According to the preset formula ratio, put the basic insulation material and additives into the high-speed mixer and stir them thoroughly to ensure that the components are evenly distributed to avoid excessively high or low local concentrations;

[0020] Monitor temperature and humidity during the mixing process and adjust if necessary to optimize the material's physical properties and processability.

[0021] Furthermore, in step S2, an automatic or manual feeding device is used to accurately measure the uniformly stirred raw materials and pour them into the mold, taking care to avoid the formation of bubbles and voids.

[0022] Furthermore, in step S3, the material in the mold is evenly compacted by vibration compaction or mechanical compaction to improve the density and strength of the product;

[0023] Monitor the pressure and time during the compaction process to ensure that the preset compaction standards are achieved while avoiding over-compaction that may cause material damage.

[0024] Further, in step S4, the compacted board is placed in a temperature-controlled curing room, the temperature and humidity conditions are set, and preliminary curing is performed;

[0025] Record the curing time and check the curing of the board regularly to ensure complete and uniform curing.

[0026] Further, in step S5, a cutting machine is used to accurately cut the plate to a specified thickness according to design requirements;

[0027] Trim the edges of the cut plates to remove burrs and uneven parts.

[0028] Furthermore, in step S6, a glass fiber mesh cloth is prepared to ensure that its thickness reaches 3 mm;

[0029] Use special adhesive or hot pressing technology to evenly adhere the fiberglass mesh cloth to the front and back sides of the board to ensure there are no bubbles or debonding.

[0030] Furthermore, in step S7, the plate compounded with the glass fiber mesh cloth is put back into the curing room for secondary curing to strengthen the bonding force between the plate and the glass fiber mesh cloth;

[0031] Adjust the curing conditions according to the material properties of the fiberglass mesh to ensure the best curing effect.

[0032] The present invention also provides a composite thermal insulation board, comprising a thermal insulation mortar layer and glass fiber mesh cloth arranged on both sides of the thermal insulation mortar layer.

[0033] Furthermore, the thermal insulation mortar layer uses graphite polystyrene particles or polystyrene particles; the thickness of the glass fiber mesh cloth is 3 mm.
