The invention discloses a heat-insulating gypsum board which is prepared from the following raw materials in parts by weight: 20.0-60.0 parts of plant straw crushed aggregates, 10.0-20.0 parts of expanded vermiculite, 4.0-16.0 parts of expanded perlite, 100.0-200.0 parts of desulfurized gypsum powder, 10.0-30.0 parts of a compound coupling agent, 12.0-80.0 parts of mixed fibers, 12.0-30.0 parts ofa water repellent, 10.016.0 parts of a catalyst and 200.0-1000.0 parts of water. Compared with the prior art, the gypsum board has the advantages that the poly(p-phenylene benzobisoxazole) fibers have lower density, higher specific strength and specific modulus than carbon fibers, excellent mechanical properties, excellent high-temperature resistance, excellent flame retardance and excellent chemical medium resistance, the heat insulation capacity of the gypsum board is greatly improved, and the water repellents have better heat insulation performance under the action of catalysts.The gypsumboard can be crosslinked at a proper temperature to form waterproof films on the surfaces of various base materials, and a layer of durable film is generated after curing, so that water repellency isgenerated, caking is prevented, and the waterproof capacity of the gypsum board is improved.
本发明公开了一种隔热石膏板，其原料按重量份包括以下组分：植物秸秆碎料20.0‑60.0份、胀蛭石10.0‑20.0份、膨胀珍珠岩4.0‑16.0份、脱硫石膏粉100.0‑200.0份、复配偶联剂10.0‑30.0份、混合纤维12.0‑80.0份、憎水剂12.0‑30.0份、触媒10.0‑16.0份、水200.0‑1000.0份，本隔热石膏板，具有以下好处：聚对亚苯基苯并二嗯唑纤维具有比碳纤维更低的密度、更高的比强度和比模量，具有优异的力学性能和耐高温性能，其阻燃性能优异，同时具有优异的耐化学介质性，大大提高了该石膏板的隔热能力，憎水剂在触媒作用下，可在适当温度下交联，在各种基材表面形成防水膜，固化后会产生一层持久性膜，使产生拒水性防止结块，从而增加该石膏板的防水能力。
