Problems solved by technology

[0002] At present, the commonly used wall insulation materials are mainly divided into two types: inorganic and organic. Organic materials are light in weight, good in heat preservation and heat insulation, but their biggest defects are poor fire safety performance, easy to burn, and large smoke and toxicity when burning. , The safety of use is not as good as that of inorganic materials
Inorganic materials have good fire resistance and are non-toxic, but their thermal insulation effect is worse than that of organic materials
[0003] As a kind of inorganic thermal insulation material, rock wool board is widely used as thermal insulation material for building exterior walls because of its excellent physical and dimensional stability and affinity with cement mortar. Although rock wool board can play a certain role However, the existing rock wool boards used for external wall insulation have high thermal conductivity, generally 0.040-0.048W/(m K), and the thermal insulation effect is not ideal, so it is difficult to meet the requirements

specific Embodiment example 1

[0031] A preparation method of composite rock wool aerogel insulation board, which comprises the following steps:

[0032] Preparation of rock wool thread: crush the ore into a cupola at a temperature of 1470°C to 1570°C, fill with liquid oxygen and melt, and the magma is thrown out by a four-roll centrifuge at a high speed of 6200 to 8000 revolutions / min. Form rock wool silk;

[0033] Prepare the rock wool bundle: spray phenolic resin binder synchronously when spinning the cotton in the four-roll centrifuge, spray silica aerogel evenly on the opening above the cotton collector, and the rock wool yarn is continuously collected during the centrifugal rotation of the cotton collector. Until the exit of the cotton collector, a composite rock wool aerogel rock wool bundle is formed;

[0034] Preparation of rock wool board: a plurality of rock wool bundles are pleated and laid flat by a pendulum machine, and then sent to a cotton pressing machine and a curing furnace, and the composite r...

specific Embodiment example 2

[0040] The present invention also proposes a composite rock wool aerogel thermal insulation belt including specific implementation case 1, which is formed by slitting the composite rock wool aerogel thermal insulation board according to the required thickness, changing the horizontal filaments into vertical filaments, and improving the tensile strength , To ensure the surface flatness.

specific Embodiment example 3

[0042] The present invention also proposes a composite board containing the composite rock wool aerogel insulation belt of specific implementation case 2 (also called a rock wool belt combination board), which includes a composite rock wool aerogel insulation board body A, a mortar layer B, and a grid The cloth C is characterized in that: the mortar layer B is located on both sides of the longitudinal section of the main body A of the composite rock wool aerogel insulation board, and a layer of mesh cloth C is also provided in the mortar layer, which has the function of reinforcement and crack resistance.

[0043] Specific implementation case 2 and specific implementation case 3 include the above composite rock wool aerogel insulation tape and its composite board, which not only has excellent thermal insulation performance and low thermal conductivity, but also can effectively improve the adhesion between the product and the mortar. The working principle of the attachment force is...

Abstract

The invention provides a novel compound rock wool and aerogel insulation board and a preparation method thereof. According to the method, aerosil is added directly in a process of preparing a rock wool board, specifically, the aerosil is evenly sprayed among fluffy rock wool filaments, the fluffy rock wool filaments containing the aerosil are constantly compressed and tightened up in a longitudinal flowing process, after compression and tightening-up are conducted, rock wool bands are formed, and the multiple rock wool bands are tiled and compressed to form the novel compound rock wool and aerogel insulation board. Therefore, the aerosil can directly parasitize the rock wool board. Meanwhile, the invention further provides a compound board containing the compound rock wool and aerogel insulation board; the compound board comprises a compound rock wool and aerogel insulation board main body A and mortar layers B, and the compound board is characterized in that the mortar layers B are located on the two sides of the vertical section of the compound rock wool and aerogel insulation board main body A.

Description

Technical field [0001] The invention relates to the technical field of thermal insulation materials for buildings, and more specifically, to a novel composite rock wool aerogel thermal insulation board, a composite board and a preparation method thereof. Background technique [0002] At present, the commonly used wall insulation materials are mainly divided into inorganic and organic categories. Organic materials are light in weight, good in heat preservation and heat insulation, but their biggest drawbacks are poor fire safety performance, easy to burn, and large smoke and toxicity during combustion. , The use safety is not as good as inorganic materials. Inorganic materials have good fire resistance and are not toxic, but their thermal insulation effect is worse than that of organic materials. [0003] As a kind of inorganic thermal insulation material, rock wool board has excellent physical and dimensional stability, and has affinity with cement mortar, so it is widely used as ...
