本申请公开了一种水分散性的生物质气凝胶涂料及其制备方法。涂料固含量≥60％，按重量份数计，包括：基料树脂，100重量份；以100重量份基料树脂为基准的增粘树脂，2重量份～60重量份；磺化生物质炭气凝胶，0.2重量份～8重量份；除甲醛助剂，2重量份～60重量份；填料，44重量份～200重量份。水分散性的生物质气凝胶涂料利用磺化生物质炭气凝胶具有非常大的比表面积及良好的亲水性，与水性涂料相容性良好，该磺化生物质炭气凝胶与涂料组分结合具备吸附甲醛的能力，而添加的除甲醛助剂可与甲醛反应，彻底降解甲醛，从而实现快速且长期有效的除甲醛效果。还利用磺化生物质炭气凝胶具有较低的导热系数，可以有效的阻隔热传质，达到隔热保温的作用。 The invention discloses a water-dispersible biomass aerogel coating and a preparation method thereof. The solid content of the coating is greater than or equal to 60%, and the coating comprises the following components in parts by weight: 100 parts of base resin; 2-60 parts by weight of a tackifying resin based on 100 parts by weight of the base resin; 0.2 to 8 parts by weight of sulfonated biomass charcoal aerogel; 2 to 60 parts by weight of a formaldehyde removal auxiliary agent; and 44 to 200 parts by weight of a filler. According to the water-dispersible biomass aerogel coating, sulfonated biomass carbon aerogel has a very large specific surface area and good hydrophilicity and is good in compatibili
