Low-cost nanopore thermal insulation material without pungent smell and preparation method thereof
The invention provides a low-cost nanopore thermal insulation material without pungent smell and a preparation method thereof. The preparation method comprises the following steps: S10, preparing a silicon dioxide gel precursor colloidal solution; s20, adding an initiation catalyst into the silicon dioxide gel precursor colloidal solution to form an elastic silicon dioxide three-dimensional gel compound; s30, a liquid phase in the silicon dioxide three-dimensional gel compound is replaced, and then the silicon dioxide nanopore heat insulation material is formed. The nanopore thermal insulation material without pungent smell provided by the invention takes silicon dioxide as a main material, and in a high-temperature pyrolysis compound, the proportion of an organic aliphatic compound containing chlorine and nitrogen is lower than 1.9 wt%, and the proportion of an organic aromatic compound containing chlorine and nitrogen is lower than 2.1 wt%. When high-temperature flames are used for burning the nanopore heat insulation compound mainly containing silicon dioxide, no pungent smell exists, and no harm is caused to eyes and noses of a human body. The nanopore heat-insulating compound is used in a sealed space for a long time and does not cause harm to human health.
本发明提供了一种无刺激性气味的低成本纳米孔隔热材料及其制备方法,制备方法包括:S10.制备二氧化硅凝胶前驱胶体溶液;S20.向二氧化硅凝胶前驱胶体溶液内加入引发催化剂,进而形成弹性的二氧化硅立体凝胶化合物;S30.置换出二氧化硅立体凝胶化合物中的液体相,进而形成二氧化硅纳米孔隔热材料。本发明提供的无刺激性气味的纳米孔隔热材料,以二氧化硅为主,高温热解化合物中,含氯和氮的有机脂肪族化合物占比低于1.9wt%,含氯和氮的有机芳香族化合物占比低于2.1wt%。用高温火焰对于该二氧化硅为主的纳米孔隔热复合物进行灼烧时,没有刺激性气味,不对人体的眼睛和鼻子产生伤害。该纳米孔隔热复合物在密封空间长时间使用,不会对人体健康产生损害。
