Problems solved by technology

Although the thermal insulation system has improved thermal insulation and fire protection compared with the existing technology, there are still some problems: because it adopts the slotting method, the overall performance of the thermal insulation board is not uniform, and the overall strength is low; The layer structure will undoubtedly increase the cost of manpower and material resources; each layer uses different materials, and the possibility of separation between each layer is still relatively large, which affects the durability of the insulation material, and then affects the insulation performance.

Embodiment 2

[0049] The difference from Example 1 is that this example uses rigid polyurethane foam as the body of the organic foam material; the light inorganic fireproof particles used are glass hollow microspheres; 1% potassium oxide is added during the preparation of the water glass solution. The dosages of inorganic binder, light inorganic fireproof particles, alkaline conditioner and ammonium polyphosphate are 6Kg, 1.6Kg, 1.6Kg and 0.8Kg respectively.

[0050] The weight ratio of the inorganic fireproof adhesive to the organic foam material body in the prepared Class A fireproof and thermal insulation material is 1:1.

[0051] In the combustion test carried out in the laboratory, there is no dripping after burning for 30 minutes at 750°C, and the mass loss is ≤35%, meeting the A2 fire protection requirements; thermal conductivity ≤0.036W / (m·K); strength ≥200kPa.

Embodiment 3

[0053] The difference from Example 2 is that the dosages of inorganic binder, light inorganic fireproof particles, alkaline conditioner and ammonium polyphosphate are 9Kg, 0.5Kg, 0.2Kg and 0.3Kg respectively.

[0054] In the combustion test carried out in the laboratory, there is no dripping after burning for 30 minutes at 750°C, and the mass loss is ≤35%, meeting the A2 fire protection requirements; thermal conductivity ≤0.036W / (m·K); strength ≥200kPa.

Abstract

The invention discloses an A-grade fireproofing thermal insulation material as well as production equipment and method thereof and belongs to the technical field of fireproofing thermal insulation materials of exterior walls of buildings. According to the method, inorganic fireproofing glue is injected into an organic foam material body, and spaces of an organic foam material are filled by utilizing the inorganic fireproofing glue, so that an inorganic fireproofing material and the organic material body can be firmly combined, fireproofing and heat retaining properties of the organic foam material are improved, and strength of the fireproofing thermal insulation material is enhanced; and besides, a concave-convex surface is formed on a die in the method, so that the surface of the pressed fireproofing thermal insulation material is uneven, mud scraping in construction can be facilitated, and strength of bonding between mud and the thermal insulation material is enhanced.

Description

technical field [0001] The invention belongs to the technical field of fireproof and thermal insulation materials for building exterior walls, and in particular relates to a class A fireproof and thermal insulation material and its production equipment and method. Background technique [0002] For a long time, organic insulation materials such as polystyrene foam (EPS, XPS) and polyurethane rigid foam (PU) have been widely used in the construction market. They have the advantages of light weight and good insulation effect, but they are flammable, easy to age, and poor in durability. , Fire accidents occur frequently in thermal insulation construction projects in various places. When a fire occurs, it will melt quickly, with large smoke, high toxicity, difficult to put out, and serious harm. [0003] In recent years, people have adopted the method of coating inorganic materials on the outer surface of organic thermal insulation materials to increase their fire resistance, and...
