Abstract

The invention discloses heat-insulating felt (board) free of dust falling and containing a nanopore heat-insulating material and a preparation method thereof and relates to the technical field of materials. The heat-insulating felt (board) comprises a fiber matrix, a bonding layer and a nanopore heat-insulating layer composed of nanopore heat-insulating material particles, the bonding layer covers fiber surface of the fiber matrix, and the nanopore heat-insulating layer is fitted to the surface, away from the fiber matrix, of the bonding layer. By the heat-insulating felt (board), the problem that damage is caused to body of personnel inhaling dust due to shedding of aerogel particle dust from existing nanopore containing heat-insulating materials, especially aerogel heat-insulating felt and the problem of lowering in heat-insulating effect of a heat-insulating material caused by constant loss of aerogel particles can be solved.

Description

technical field [0001] The invention relates to the field of material technology, in particular to a thermal insulation felt board containing nanoporous thermal insulation materials that does not shed dust and a preparation method thereof. Background technique [0002] There are three ways of heat conduction: radiation, convection and conduction. [0003] Heat transfer refers to the process of heat transfer from a space with a higher temperature to a space with a lower temperature. Increasing the length of the conduction path during transfer can reduce heat conduction; reducing the size of the void can block heat convection. Nanoporous materials have less conductive media and long paths, and are rich in nanopores inside, which have superior thermal insulation performance. Therefore, adding nanoporous materials to thermal insulation materials can effectively reduce the thermal conductivity, and are greatly valued by the field of thermal insulation . [0004] Since the curre...
