The invention discloses a light durable building insulation board and a preparation method thereof. The building insulation board comprises a reinforced foam insulation layer, wherein skeleton boardsare fixedly compounded on the two sides of the reinforced foam insulation layer. According to the method, firstly, aldehyde groups of glutaraldehyde are added into a phenolic resin synthesis system toreact and connect with phenol, so that the crosslinking speed of subsequent formaldehyde and phenol is reduced, the controllability of subsequent foaming is improved, and the foaming quality is improved; meanwhile, the molecular weight of a polymerization product can be improved, and the toughness and the compression strength of the formed phenolic resin are improved; in addition, the modified lignocellulose and the inorganic nanoparticles are added into the phenolic resin prepared in the second step, so that the phenolic resin is reinforced through the lignocellulose and the inorganic nanoparticles, the toughness and strength of the cured phenolic resin are improved; under the condition that the foaming effect of the phenolic resin is not affected, the strength of the phenolic resin is improved, so that the prepared building insulation board has the effects of light weight and good strength.
本发明公开了一种轻质耐用建筑保温板及其制备方法，该建筑保温板包括强化泡沫保温层，强化泡沫保温层的两面固定复合有骨架板；本发明首先通过向酚醛树脂合成体系中加入使戊二醛的醛基与苯酚反应连接，从而降低后续甲醛与苯酚的交联速度，从而提升后续发泡的可控性，提升发泡质量，同时还能够提升聚合产物分子量，从而提升所成酚醛树脂的韧性与压缩强度；另外通过向第二步中制备得到的酚醛树脂中加入改性的木质纤维素以及无机纳米颗粒，通过木质纤维素与无机纳米颗粒对酚醛树脂进行补强，提升固化后酚醛树脂的韧性与强度，在不影响酚醛树脂发泡效果的条件下，提升了酚醛树脂的强度，因此使制备得到的建筑保温板具有轻质以及良好的强度的效果。
