Abstract

The invention discloses a fabricated building structure insulation board, and belongs to the technical field of fabricated constructions. According to the fabricated building structure insulation board, raw materials of an existing insulation board are improved, magnet blocks are inlaid in the surface of the insulation board in a staggered mode, and flame-retardant balls are externally embedded in the surface of the insulation board, so when the insulation board encounters open fire, the externally-embedded flame-retardant balls sense the high temperature firstly and then expand gradually; the fire extinguishing material is released to extinguish open fire until the fire extinguishing material expands to a certain degree and then explodes; once the fire is large and cannot be extinguished, the externally-embedded flame-retardant balls can be further disintegrated and release magnetic flame-retardant materials, and then the magnetic flame-retardant materials are transferred out of the externally-embedded flame-retardant balls and cover the surface of the heat preservation plate under the magnetic attraction effect of the magnet blocks, and an integral fireproof layer is formed to carry out flame-retardant protection on the insulation board; compared with an existing insulation board, the fireproof and flame-retardant effects of the insulation board are remarkably improved, and the application of the insulation board in the field of prefabricated buildings is effectively expanded.

Description

technical field

[0001] The invention relates to the technical field of prefabricated buildings, and more specifically relates to a thermal insulation board for prefabricated building structures. Background technique

[0002] Prefabricated building refers to the transfer of a large number of on-site operations in the traditional construction method to the factory, where the building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in the factory, and transported to the construction site. Reliable connections are assembled and installed on site.

[0003] Prefabricated buildings mainly include prefabricated concrete structures, steel structures, modern wooden structures, etc., because of the use of standardized design, factory production, assembly construction, information management, and intelligent applications, they are representatives of modern industrial production methods.

[0004] The insulation board ...

Examples

Embodiment 1

[0040] see figure 1 , a prefabricated building structure insulation board, comprising the following components in parts by weight: 150 parts of polystyrene resin, 7.5 parts of foaming agent, 15 parts of glass fiber, 3 parts of polypropylene, 6 parts of silicon dioxide, carbonic acid 5 parts of calcium, 1 part of magnesium hydroxide, 2 parts of ammonium polyphosphate, 2 parts of nucleating agent, 5 parts of flame retardant, 10 parts of magnet block and 10 parts of embedded flame retardant ball.

[0041] The blowing agent is one of n-pentane or isopentane.

[0042] The nucleating agent is prepared by mixing mica, chrysophyte and sodium benzoate at a mass ratio of 1:1:2.

[0043] The magnet blocks and the embedded flame-retardant balls are evenly inlaid on the outer surface of the same side of the insulation board, and the magnet blocks and the embedded flame-retardant balls are alternately distributed. After the flame-retardant materials are released, the embedded flame-retarda...

Embodiment 2

[0051] see figure 1 , a prefabricated building structure insulation board, comprising the following components in parts by weight: 175 parts of polystyrene resin, 12 parts of foaming agent, 18 parts of glass fiber, 3.5 parts of polypropylene, 8 parts of silicon dioxide, carbonic acid 8 parts of calcium, 1.5 parts of magnesium hydroxide, 3 parts of ammonium polyphosphate, 3 parts of nucleating agent, 10 parts of flame retardant, 11 parts of magnet block and 12 parts of externally embedded flame retardant balls.

[0052] The rest are consistent with Example 1.

Embodiment 3

[0054] see figure 1 , a prefabricated building structure insulation board, comprising the following components in parts by weight: 200 parts of polystyrene resin, 15 parts of foaming agent, 20 parts of glass fiber, 4 parts of polypropylene, 10 parts of silicon dioxide, carbonic acid 12 parts of calcium, 2 parts of magnesium hydroxide, 4 parts of ammonium polyphosphate, 4 parts of nucleating agent, 15 parts of flame retardant, 12 parts of magnet block and 15 parts of external flame retardant ball.

[0055] The rest are consistent with Example 1.

[0056] The present invention can improve the existing insulation board raw materials, and inlaid magnet blocks and externally embedded flame-retardant balls on the surface of the insulation board in a staggered manner. Expansion until it expands to a certain extent and bursts, and releases the fire extinguishing material to extinguish the open fire. Once the fire is too large to be extinguished, the embedded flame retardant ball will...
