Sand-wood composite material and preparation method thereof
The invention belongs to the technical field of composite materials, and particularly discloses a sand-wood composite material and a preparation method thereof. Phenolic resin, polystyrene, attapulgite, a coupling agent, titanium dioxide, silica sand and the like are matched in a specific proportion for use for the first time, the coupling agent can improve the dispersity of titanium dioxide and silica sand in a system, titanium dioxide and silica sand are prevented from being gathered into a cluster in the system, and the heat preservation performance of the product is improved; meanwhile, the coupling agent can firmly couple titanium dioxide and silica sand into a base material formed by phenolic resin, polystyrene and the like, so that the product is stable in structure and has lastingheat preservation performance; titanium dioxide and the coupling agent are coupled and uniformly dispersed in the whole system, so that the product has waterproof performance, the water absorption phenomenon of the product after long-time use is avoided, the water content of the product is reduced, and the heat preservation durability of the product is improved; and glass fibers can maintain the pore structure of the product, the bonding compactness among all raw materials is improved, and the heat preservation performance of the product is improved.
本发明属于复合材料技术领域，具体公开了一种砂木复合材料及其制备方法。其首次采用酚醛树脂、聚苯乙烯、凹凸棒土、偶联剂与二氧化钛和硅砂等在特定比例下配合使用，利用偶联剂能提高二氧化钛和硅砂在体系内的分散性，避免两者在体系内聚集成团，提高产品的保温性能；同时偶联剂也能将二氧化钛和硅砂牢固偶联于酚醛树脂和聚苯乙烯等形成的基体材料中，使产品结构稳定，使其具有持久的保温性能；二氧化钛与偶联剂耦合并均匀分散于整个体系内，使产品具有防水性能，避免产品在长时间使用后存在的吸水现象，降低了产品的含水率，提高了产品的保温持久性；玻璃纤维能维持产品孔隙结构，提高各原料间结合密实度，提高了产品的保温性能。
