The invention relates to the technical field of thermal insulation materials, and provides a flame-retardant thermal insulation rock wool board, which is prepared from the following raw materials in parts by weight: 30 to 40 parts of basalt fiber, 10 to 15 parts of perlite, 30 to 35 parts of cement, 4 to 6 parts of carboxymethyl cellulose, 6 to 8 parts of modified magnesium hydroxide, 2 to 4 parts of water repellent and 12 to 15 parts of water. The modified magnesium hydroxide is obtained by modifying magnesium hydroxide with 3-ethoxy-4-ethoxycarboxyphenylacetic acid. By means of the technical scheme, the problems that in the prior art, rock wool boards are high in heat conductivity coefficient and low in tensile strength and combustion grade are solved.
本发明涉及保温材料技术领域，提出了一种阻燃型保温岩棉板，包括以下重量份组分原料：30~40份玄武岩纤维、10~15份珍珠岩、30~35份水泥、4~6份羧甲基纤维素、6~8份改性氢氧化镁、2~4份憎水剂、12~15份水；所述改性氢氧化镁为氢氧化镁经3‑乙氧基‑4‑乙氧羧基苯乙酸改性得到。通过上述技术方案，解决了现有技术中岩棉板导热系数高、抗拉强度和燃烧等级低的问题。
