The invention discloses a building board for heat insulation and a preparation method thereof, and relates to the technical field of building decoration. The prepared building board for heat insulation comprises a modified phenolic resin composite board layer and a modified phenolic foam layer, the modified phenolic resin composite board layer is prepared from purified halloysite nanotubes, jute fibers, sodium hydroxide, 3-aminopropyl triethoxy silane and phenolic resin, silanol and hydroxyl of hydrolyzed 3-aminopropyl triethoxy silane are subjected to condensation, and covalent bonds are generated with-OH on the surfaces of the jute fibers, so that the halloysite nanotubes are attached to the surfaces of the fibers, and the modified phenolic resin composite board layer is formed. Heat and oxygen exchange can be physically blocked, and the flame retardance of the composite material is enhanced; the modified phenolic foam layer is prepared from terephthalyl alcohol, tannin, formaldehyde, phenol and sodium hydroxide, a phenolic resin matrix is generated through methylene bridge connection, auxiliaries are added, a three-dimensional body structure with a long branch chain can be formed in a cross-linking mode during foaming, and the modified phenolic foam layer is high in percentage of closed area, low in heat conductivity coefficient and good in heat insulation performance.
本发明公开了一种隔热用建筑板材及其制备方法，涉及建筑装修技术领域。本发明制备的隔热用建筑板材，包括改性酚醛树脂复合板层、改性酚醛泡沫层；改性酚醛树脂复合板层是由纯化埃洛石纳米管、黄麻纤维、氢氧化钠、3‑氨丙基三乙氧基硅烷、酚醛树脂制得，水解的3‑氨丙基三乙氧基硅烷的硅醇和羟基发生缩合，与黄麻纤维表面的‑OH生成共价键，使得埃洛石纳米管附在纤维表面，能够物理阻隔热氧交换，增强了复合材料的阻燃性；改性酚醛泡沫层是由对苯二甲醇、单宁、甲醛、苯酚、氢氧化钠制得，通过亚甲基桥连接，生成酚醛树脂基体，加入助剂，发泡时能交联形成较长支链的三维体型结构，闭孔率高，导热系数低，隔热性好。
