Fireproof thermal insulation material containing calcium hydroxide
The invention belongs to the field of building fireproof thermal insulation materials, and particularly discloses a calcium hydroxide-containing fireproof thermal insulation material, which is prepared from the following raw materials in parts by weight: 100 parts of modified calcium hydroxide, 60 to 80 parts of fly ash, 30 to 60 parts of tobermorite, 20 to 50 parts of ceramic powder, 20 to 40 parts of aluminum oxide, 10 to 30 parts of glass fiber, 10 to 20 parts of desulfurized gypsum and 10 to 20 parts of ceramic fiber. Modified calcium hydroxide is used as a main raw material to produce the fireproof thermal insulation material, industrial waste fly ash, tobermorite, ceramic powder and the like are added to prepare the fireproof thermal insulation material, the raw materials are easy to obtain, the fireproof thermal insulation material has good thermal insulation effect and fireproof performance and excellent mechanical performance, the compressive strength is larger than 8 Mpa and reaches the A2 combustion grade, and the fireproof thermal insulation material belongs to a non-combustible building material and is worthy of popularization and application. Further, the applicant modifies hydroxypropyl methylcellulose, the compressive strength of the obtained test block is further improved and reaches 10 Mpa or above, the mechanical property is good, and the material is low in preparation cost and wide in application range.
本发明属于建筑防火保温材料领域，具体公开了一种含有氢氧化钙的防火保温材料，按重量份数计算，包括以下原料：改性氢氧化钙100份、粉煤灰60‑80份、托贝莫来石30‑60份、陶瓷粉20‑50份氧化铝20‑40份、玻璃纤维10‑30份、脱硫石膏10‑20份、陶瓷纤维10‑20份，本发明使用改性氢氧化钙为主要原料生产防火保温材料，添加工业废弃物粉煤灰和托贝莫来石、陶瓷粉等制成，原料易得，具有良好的保温效果和防火性能，其机械性能优异，抗压强度均大于8Mpa，并且均达到了A2的燃烧等级，属于不燃性建筑材料，进一步的申请人对羟丙甲纤维素进行改性，获得的试块，抗压强度实现了进一步的提升，达到10Mpa以上，机械性能好，本发明所述的材料制备成本低，应用范围广。
