Description

Aerogel phenolic foam board with solar radiation barrier and fireproof function

The present invention relates to an aerogel phenolic foaming board with solar radiation barrier and fireproof function, in particular to a sheet material in which a plurality of aerogel particles are arranged in a phenolic foaming board, which not only has better heat insulating properties, And has fire and flame resistance.

The existing thermal insulation methods for building outer casings are mostly coated with thermal insulation coating on the surface of the building envelope. However, this method is easy to cause performance degradation due to the deposition of suspended particles in the air on the roof surface and the influence of solar radiation on the roof coating. The insulation effect of the roof decreases as the service life increases.

In addition, placing the insulating material on the inside of the roof or exterior wall is also a common method of insulation. For example, the Republic of China Patent Publication No. M541491 discloses an "insulated roof" comprising a floor structure, a drainage insulation layer, a fiber layer, and a water permeable cover layer, wherein the drainage insulation layer comprises at least one drainage The plate defines a heat insulating space; the water permeable cover layer prevents the sun from directly illuminating the floor structure, and the air in the heat insulating space can block most of the heat energy from being transmitted to the floor structure. Although the above structure can achieve the heat insulation effect, the structure is relatively complicated.

Commonly used heat insulating materials are polyurethane (PU) foamed sheets or rock wool. For example, the "insulation board for building construction" of the Republic of China Patent No. M453698, which discloses that the heat insulating board contains polyurethane hard foaming material. A rectangular body made. Republic of China Patent Notice M301910 "Improvement of Heat Insulation Structure" reveals a heat-insulating material structure that is easy to assemble and use on roofs and wall panels. It is mainly composed of rock wool material between the upper and lower steel plates. The layer, by virtue of the characteristics of rock wool and steel plate, and the structure of a small number of layers, achieves the advantages of heat insulation, light weight and cost saving. However, although PU foamed sheets have excellent heat insulating properties, PU foamed sheets are a flammable material. Although rock wool is a non-combustible material, its thermal insulation performance is inferior to that of PU foaming board, and in the actual use stage, rock wool will make the heat insulation performance worse due to moisture absorption.

A conventional phenolic foamed sheet is a flame-resistant material. For example, the Republic of China Patent Publication No. I468293 discloses a "phenolic foamed sheet having a honeycomb structure" which is formed into a honeycomb interior having a honeycomb body by a simplified preparation process. Hollow, the density of the whole board is significantly reduced, and the thermal insulation performance and fire resistance are improved. However, the general phenolic foaming materials on the market are mostly three-grade flame-resistant or fire-resistant secondary. If it is necessary to improve the flame resistance of the phenolic foamed board, it is usually necessary to additionally add a flame retardant.

The reason is that the creators have created a number of defects in the actual implementation of the existing insulation and fire-resistant flame retardant panels. Based on years of rich experience in design and development and actual production of the relevant industries, the creators have improved the creation of a solar radiation barrier and fire prevention function. The gel phenolic foaming board is intended to provide a sheet material having the function of insulating solar radiation and fire resistance; thereby, the creation not only has excellent heat insulating effect, but also has the effect of fireproof and flameproof first stage.

In order to achieve the above-mentioned implementation purposes, the present author proposes an aerogel phenolic foamed board having solar radiation barrier and fireproof function, comprising a body layer comprising a plurality of aerogel particles disposed in a phenolic foamed sheet. And at least one aluminum foil layer to cover at least the body layer a surface.

In one embodiment of the present invention, the aluminum foil layer has a surface emissivity of 0.901, a visible light reflectance of 75.59, a solar reflectance of 78.47, and an ultraviolet reflectance of 72.40.

In one embodiment of the present invention, the body layer is coated with an aluminum foil layer on both the upper and lower surfaces to improve the reflectivity and emissivity characteristics of the entire surface to achieve the function of isolating solar radiation.

In this way, the creation can not only effectively block the solar radiation to enhance the heat insulation effect, but also has the effect of fireproof and flameproof first class.

One side is coated with an aluminum foil layer (2) to form a structure as shown in the first figure; or an aluminum foil layer (2) may be coated on both the upper and lower sides of the body layer (1), that is, As shown in the second figure, since the aluminum foil has a high reflectance (as indicated by the arrow in the second figure) and a high emissivity, solar radiation can be effectively isolated.
