Detailed Description

The present invention will be further explained with reference to the following examples and the accompanying drawings.

In the embodiment, as shown in fig. 1 and 2, the graphite a-grade fireproof cooling and heating radiation decoration integrated board is characterized by comprising a radiation core board 1 and a fireproof shell 2, wherein the fireproof shell 2 is formed by compounding multiple layers of calcium silicate boards, a water pipe 3 which is a PE-XA pipe with the thickness of 8 to 10mm × 1.5mm is arranged in the radiation core board 1, a closed cavity 201 is formed in the fireproof shell 2, and the radiation core board 1 is placed in the closed cavity 201.

In the embodiment, the radiation core plate 1 is an expanded graphite plate, and is obtained by expanding expandable graphite with 50-100 meshes in a high-temperature expansion furnace, wherein the expansion temperature is 900-1200 ℃, the expansion rate is preset to be 80 times, and the thickness is 10-15mm. Graphite has a melting point of 3000 ℃ or higher and has high temperature resistance, but graphite is not resistant to oxidation, and is oxidized at a high temperature of about 400 ℃ in the presence of oxygen, and oxidation is accelerated at higher temperatures. Therefore, the purpose of air isolation is achieved by coating the fireproof coating on the surface of the radiation core plate 1, so as to improve the fireproof performance of the radiation core plate 1. In addition, a gap between the water pipe 3 and the fireproof shell 2 is provided with fireproof sealant for isolating air.

In the embodiment, as shown in fig. 1, the fireproof casing 2 includes a base calcium silicate board 202, an intermediate calcium silicate board 203, and a surface calcium silicate board 204, which are sequentially combined from top to bottom, and are of a double-layer structure. As shown in fig. 2, the intermediate-layer calcium silicate board 203 is of a frame structure, a closed cavity 201 is formed inside the intermediate-layer calcium silicate board, and the intermediate-layer calcium silicate board 203 of the frame structure is formed by splicing calcium silicate strips. The calcium silicate board is also called gypsum composite board, is a multielement material, is generally compounded by natural gypsum powder, white cement, glue and glass fiber, has the performances of fire prevention, moisture prevention, sound insulation, heat insulation and the like, and the calcium silicate is a grade A1 fireproof flame-retardant material, and the fireproof shell 2 made of the calcium silicate board can ensure good fireproof performance. And the calcium silicate board can slowly radiate heat indoors to adjust the room temperature, so that the room temperature is ensured to be balanced and stable.
