Moistureproof flame-retardant bamboo-wood fiber wallboard and preparation method thereof
The invention discloses a moisture-proof flame-retardant bamboo-wood fiber wallboard and a preparation method thereof, and relates to the technical field of home decoration materials. When the damp-proof flame-retardant bamboo-wood fiber wallboard is prepared, firstly, vinyl trimethoxy silane is polymerized to prepare polyhedral organic silicon, the polyhedral organic silicon is used as a star core, polyvinyl pyridine and poly (1, 3-butadiene) are reacted and activated by n-butyllithium, and then the activated product reacts with the polyhedral organic silicon to prepare star-shaped organic silicon; carrying out sealing treatment on polyisocyanate by using sodium hydrogen sulfite, controlling the polyisocyanate subjected to the sealing treatment to be semi-unsealed and react with the hydrolyzed star-shaped organic silicon to prepare modified star-shaped organic silicon, carrying out reaction, mixing and stirring the modified star-shaped organic silicon, the activated bamboo and wood fiber powder, polyvinyl chloride, acetone and stearic acid, and carrying out extrusion molding. And adding calcium carbonate, mixing and stirring, and carrying out high-temperature hot pressing to obtain the moisture-proof flame-retardant bamboo-wood fiber wallboard. The prepared damp-proof flame-retardant bamboo-wood fiber wallboard has excellent damp-proof performance, flame-retardant performance and breaking strength.
本发明公开了一种防潮阻燃竹木纤维墙板及其制备方法，涉及家装材料技术领域。本发明在制备防潮阻燃竹木纤维墙板时，先将乙烯基三甲氧基硅烷进行聚合，制得多面有机硅，以多面有机硅为星核，用正丁基锂对聚乙烯吡啶和聚1,3‑丁二烯反应活化后再与多面有机硅反应制得星形有机硅，用亚硫酸氢钠对多异氰酸酯进行封闭处理，控制封闭处理后的多异氰酸酯半解封并与水解后的星形有机硅反应，制得改性星形有机硅反应，将改性星形有机硅、活化后的竹木纤维粉、聚氯乙烯、丙酮、硬脂酸混合搅拌，再加入碳酸钙混合搅拌后进行高温热压制得防潮阻燃竹木纤维墙板。本发明制备的防潮阻燃竹木纤维墙板具有优良的防潮性能、阻燃性能和断裂强度。
