Preparation Method of Surface Thermal Protection System Based on
Fiber-reinforced Silica-alumina Aerogel
Technical Field
The invention relates to the technical field of thermal protection materials, in particular to a preparation method of thermal protection system based on fiber-reinforced silica- aluminum aerogel surface.
Background Technology
Aerogel is a kind of solid material with porous structure formed by nanoparticle polymerization. It has many excellent properties such as high porosity, low density, large specific surface area, low thermal conductivity, low sound velocity and low refractive index.
These excellent properties make aerogels widely used in a variety of fields, such as high efficiency thermal insulation materials, catalysts and catalyst carriers, and aerospace materials.
In the scope of current technology, the thermal protection composite material is usually a special functional composite material to ensure the normal operation of the aircraft in a special aerodynamic thermal environment, which not only protects the aircraft from burning and damage in the aerodynamic thermal environment, but also keeps the temperature of the protected structure and its internal device within a given temperature range, and does not affect the use of excessive heat introduction. At present, the application of thermal protection composite materials is more and more widely, such as used in the power battery of new energy vehicles, which also has higher and higher performance requirements for thermal protection composite materials, not only to meet the flame retardant, heat insulation performance, but also have light weight, high mechanical strength and other properties; traditional thermal protection materials often use fiber-reinforced materials impregnated with flame retardant resin paste, and optimize thermal insulation performance by increasing the amount of thermal protection layer.
However, the density of fiber-reinforced resin materials is often higher and the thickness is larger, and when applied in the field of power batteries, the battery modules often require thinner ablative materials.
Therefore, we need a preparation method based on the fiber-reinforced silica- aluminum aerogel surface thermal protection system to solve the problem of large thickness of the existing battery module scorch-resistant material, which can ensure that the ablative material still has high performance at a thin thickness.
Description of the Invention
The invention aims to provide a preparation method based on a fiber-reinforced silica- aluminum aerogel surface thermal protection system to solve the problem of large thickness of the existing battery module burn-resistant material proposed in the background technology, and to ensure that the ablative material still has high performance at a thin thickness.
To achieve the above purpose, the invention provides the following technical scheme:
A preparation method based on a fiber-reinforced silica-aluminum aerogel surface thermal protection system, the method comprises the following steps: - Prefabricating fiber-reinforced silica-aluminum aerogel; - Applying high temperature resistant composite treatment; - Laminating burn-resistant layer.
Preferably, prefabricated fiber-reinforced silica-aluminum aerogel include: - After cleaning up the impurities, the fiber is soaked in acidic solution, stirred for pretreatment, and then filtered, washed, dried to get the pretreatment fiber;
The aluminum source, silicon source, water and ethanol are mixed and stirred evenly, the epoxide is added, the pretreatment fiber is added to the mixture after continuous stirring, and the sol solution is obtained by stirring. The substrate is immersed in the sol solution and absarbed fully, and the gel reaction is carried out for 20-30h, and transferred to the mold, and the aging solution is added for aging, and the composite gel is obtained.
The composite gel was put into the drying equipment, ethanol solvent was used as the drying medium, and the fiber-reinforced silica-aluminum aerogel was obtained after drying.
Specific operations of the preferred, high temperature resistant composite treatment pair include: - Two layers of fiber-reinforced silica-aluminum aerogel are prepared, and a filler is added between the two layers of fiber-reinforced silica-aluminum aerogel. - Epoxy resin glue is applied on the inside of the two layers of fiber-reinforced silica- aluminum aerogels to keep the filling between the two layers of fiber-reinforced silica- aluminum aerogels. The two layers of fiber-reinforced silica-aluminum aerogels are bonded by epoxy resin glue, and the first bonding layer is formed after the epoxy resin glue is dried. - Epoxy resin glue is applied to the outside of the two layers of fiber-reinforced silica- aluminum aerogel, and the fiber cloth is glued to the outside of the two layers of fiber- reinforced silica-aluminum aerogel, and the second bonding layer and thermal insulation layer are formed on the outside of the two layers of fiber-reinforced silica-aluminum aerogel.
Specific operations for the preferred, laminated burn-resistant layer include: - The heat absorbing layer is prepared by melting the phase change material and adding it into the porous material.
- The surface of the heat-absorbing layer is sprayed with thermal insulation coating and dried. - Several heat-resistant composite fiber-reinforced silica-aluminum aerogels and heat-absorbing layers sprayed with heat-resistant coating were laid on top of each other to get laminated materials. The sides of the laminated materials were sealed with heat-resistant resin adhesive, and the ablation-resistant aerogels were cured by hot pressing. A thermal protection system based on fiber-reinforced silica-aluminum aerogels with high temperature and burning resistance was prepared by several ablative aerogels.
Compared with the current technology, the beneficial effects of the invention are:
The preparation method of the fiber-reinforced silica-aluminum aerogel surface thermal protection system is based on the fact that most of the pores are filled with silica aerogel with low thermal conductivity, which reduces the thermal bridge effect caused by the fiber overlapping with each other, greatly reduces the solid heat transfer, and also inhibits the radiation heat transfer and convective heat transfer, so that it has high temperature resistance. A layer of heat insulation coating is applied on the surface of the heat-absorbing layer to separate the fiber-reinforced resin material from the phase change material, so that the two do not contact directly to ensure the normal curing of the limited-position reinforced resin material. In addition, the heat insulation coating insulates the heat, and in the process of laminating the heat-absorbing layer, the ablative layer and the protective layer, the solid phase change material can avoid a certain liquid phase change phenomenon due to the high temperature caused by the solidification of the adhesive layer.

The surface of the heat- absorbing layer is sprayed with thermal insulation coating and dried; Several heat-resistant composite fiber-reinforced silica-aluminum aerogels and heat-absorbing layers sprayed with heat-resistant coating were laid on top of each other to get laminated materials.
