一种纳米气凝胶绝热保温涂料
摘要：
本发明公开一种纳米气凝胶绝热保温涂料，属于特殊涂料技术领域。该气凝胶绝热保温涂料包括按质量百分含量计的组分：水5‑15、助剂1‑6、颜填料20‑55、粘结剂10‑30、偶联剂1‑3、阻燃剂5‑15、红外遮光剂5‑20。其中颜填料包括功能性低导热率填料：纳米二氧化硅气凝胶；体质填料：滑石粉、轻质碳酸钙、硅灰石；功能性防腐颜料磷酸锌；粘结剂包括水溶性有机硅树脂、水性丙烯酸耐高温乳液、水性丙烯酸弹性乳液。本发明的涂料导热系数低，隔热效果优；具有良好的防腐效果，可减少防腐底漆的使用；且具有自洁疏水的效果。
摘要（英）：

The invention discloses a nanometer aerogel heat insulation coating, and belongs to the technical field of special coatings. The aerogel heat insulation coating is prepared from, by mass, 5-15 parts of water, 1-6 parts of auxiliaries, 20-55 parts of pigments and fillers, 10-30 parts of adhesives, 1-3 parts of a coupling agent, 5-15 parts of a fire retardant and 5-20 parts of an infrared light screening agent, wherein the pigments and the fillers include a functional low-heat-conducting-rate filler of nanometer silicon dioxide aerogel, extender fillers of talcum powder, light calcium carbonateand wollastonite, and a functional anti-corrosive filler of zinc phosphate; the adhesives include water soluble organic silicon resin, waterborne acrylic acid high temperature resistance emulsion andwaterborne acrylic acid elastic emulsion. The coating is low in heat conducting coefficient and excellent in heat insulation effect, has the good anti-corrosive effect, can reduce consumption of anti-corrosive primer and has the self-cleaning lyophobic effect.
