Preparation method of nanocellulose reinforced silicon dioxide aerogel composite material
The invention discloses a preparation method of a silicon dioxide aerogel composite material reinforced by a nanocellulose pouring method, and belongs to the field of composite materials. The composite material is compounded by taking silicon dioxide aerogel as a matrix and nano-crystalline cellulose extracted from straw as a reinforcing body through a pouring method. The nanocellulose reinforced silicon dioxide aerogel composite material disclosed by the invention is simple to prepare, higher in strength and lower in cost while keeping low thermal conductivity and reducing slag and powder falling phenomena, and further achieves the effects of waste utilization, environmental protection and saving.
本发明公开了一种纳米纤维素浇注法增强的二氧化硅气凝胶复合材料的制备方法，属于复合材料领域。所述复合材料包括以二氧化硅气凝胶为基体，秸秆提取的纳米纤维素为增强体，采用浇注法复合而成的复合材料。本发明的纳米纤维素增强二氧化硅气凝胶复合材料制备简单，在保持低热导率同时强度更高、掉渣掉粉现象减少、成本更低，还达到废物利用、环保节约的效果。
