Detailed Description
The utility model is further described with reference to the following figures and examples.
In the examples, as shown in fig. 1: an AB composite fireproof heat-insulation board comprises a heat-insulation core board 1, wherein an A-level fireproof heat-insulation board 2 is glued on one side of the heat-insulation core board 1 through a glue layer 3, and protective layers 4 are arranged on the outer sides of the heat-insulation core board 1 and the A-level fireproof heat-insulation board 2; the polyphenyl granules 201 in the class A fireproof heat-insulation board 2 have diameters of various specifications. In the embodiment, the class a fireproof insulation board 2 is generally coated by slurry consisting of cement, rubber powder, polyphenyl particles and an additive, wherein the additive is one or more of fly ash, yellow sand and gypsum. In the embodiment, the heat-insulation core plate 1 and the A-level fireproof heat-insulation plate 2 are compounded into a whole, so that the heat-insulation performance of the composite heat-insulation plate is ensured, and the fireproof performance of the composite heat-insulation plate is improved, so that the composite heat-insulation plate is safer and more reliable; the protective layer 4 is compounded on the outer side, so that the overall strength of the composite protective layer is improved, and the composite protective layer is prevented from being damaged; polyphenyl granule 201 that A level fire prevention heated board 2 adopted is the variation in size, can the gomphosis each other, and less granule is filled in the clearance of great granule, combines inseparabler to A level fire prevention heated board 2's thermal insulation performance obtains improving. Specifically, in the examples, the diameter of the polyphenyl granules 201 has two specifications of 1-2mm and 3-5 mm. Therefore, when the A-level fireproof heat-insulation board 2 is poured and coated on the heat-insulation core board 1, the small polyphenyl granules 201 with the diameter of 1-2mm can be well filled in gaps among the large polyphenyl granules 201 with the diameter of 3-5mm, so that the proportion of the polyphenyl granules 201 in the A-level fireproof heat-insulation board 2 is correspondingly increased, and the heat insulation performance of the A-level fireproof heat-insulation board is improved. Further, the number of the polyphenyl granules 201 having a diameter of 1 to 2mm is 2 to 4 times the number of the polyphenyl granules 201 having a diameter of 3 to 5mm, so that the smaller polyphenyl granules 201 are better dispersed and filled. Meanwhile, the slurry composition of the A-level fireproof insulation board 2 comprises A-level fireproof materials such as cement, fly ash and yellow sand, so that the fireproof performance of the A-level fireproof insulation board can be ensured.
