Abstract

The invention provides a preparation method of a nano porous high-efficiency heat insulation board, belonging to the field of nano porous heat insulation materials. The preparation method comprises the following processes: uniformly mixing nano powder with fiber, a bonding agent, an opacifier, a plasticizer, a drying control agent, a dispersant and a right amount of dry-and-wet degree regulating reagent in a mechanical and chemical dispersion combined method; moulding in a manner of dry pressing moulding, curtain coating moulding or extrusion moulding and the like; and controlling drying conditions, drying a moulded sample, and then coating a reflecting layer with certain thickness and material quality, thus obtaining the nano porous high-efficiency heat insulation board. The invention has the advantages that the preparation method is simple and feasible, the prepared nano porous heat insulation board has high strength, uniform hole structure and good heat insulation performance.

Description

technical field [0001] The invention relates to a preparation method of a nanoporous high-efficiency heat insulation board, belonging to the field of nanoporous heat insulation materials. technical background [0002] With the development of social economy, the global energy consumption has risen sharply, and the shortage of energy has become a worldwide problem. One of the most effective measures to save energy is to adopt new technologies and new processes to develop high-efficiency heat insulation materials. The use of good thermal insulation materials in the industry is beneficial to reduce product energy consumption, reduce production costs, reduce the volume of the insulation layer, reduce the volume of equipment and facilities, and achieve a beautiful and coordinated effect, which has great social and economic benefits. [0003] At present, traditional thermal insulation materials are difficult to meet the higher requirements for thermal insulation materials such as ...
