摘要：
本发明提供一种纳米复合无石棉绝热毡，其为富含纳米级封闭微孔网状结构的弹性复合材料，由下列重量百分比的成分组成：纳米硅6～8.5wt％、水镁石34～42wt％、海泡石18～34wt％、硅酸铝12～27wt％、无机活性土6～8wt％、松解剂1.6～2wt％、改性分散剂0.7～0.9wt％、络合剂0.01～0.02wt％，余量为水；其中，所述纳米复合无石棉绝热毡，其可溶性氯离子含量≤100毫克/千克，可溶性硅酸根与钠离子含量之和≥10000毫克/千克。本发明的产品保温性能好、使用温度高、回弹率好，产品内无石棉成分。
摘要（英）：

The invention provides a nanometer composite non-asbestos heat insulation felt which is an elastic composite material enriched in a nanoscale closed porous meshed structure. The nanometer composite non-asbestos heat insulation felt comprises the following components in percentage by weight: 6-8.5wt% of nanometer silicon, 34-42wt% of brucite, 18-34wt% of sepiolite, 12-27wt% of aluminum silicate, 6-8wt% of inorganic active soil, 1.6-2wt% of debonding agent, 0.7-0.9wt% of modified dispersing agent, 0.01-0.02wt% of complexing agent and the balance of water. According to the nanometer composite non-asbestos heat insulation felt, the content of soluble chloride ions is less than or equal to 100mg/kg, and the sum of the content of soluble silicate and sodium ions is more than 10000mg/kg. The product is good in thermal insulation properties, high in service temperature and high in rebound rate, and an asbestos component does not exist in the product.
