Composite material with good thermal insulation effect and preparation method thereof

Abstract

The invention discloses a composite material with good thermal insulation effect and a preparation method thereof, and relates to the field of thermal insulation materials, including thermal insulation base plate, thermal insulation reinforcing rib, thermal insulation inner core and thermal insulation fiber composite coating. The thermal insulation base plate is a carbon-carbon composite board, the thermal insulation reinforcing rib is a carbon-carbon composite column, the thermal insulation inner core polyurethane foam, and the thermal insulation fiber composite coating is composed of the following raw materials: silica gas 33-40 parts by mass of gel; 20-25 parts by mass of carbon dioxide aluminum aerogel. The invention adopts a variety of thermal insulation materials and has different thermal insulation effects through the provided thermal insulation substrate, thermal insulation reinforcing rib, thermal insulation inner core and thermal insulation fiber composite coating, and the thermal insulation inner core adopts polyurethane foam so that The overall weight of the thermal insulation material is light, and the interior of the thermal insulation material is evacuated to a vacuum, which makes the heat transmission effect of the material worse, and the thermal insulation effect is better. Better pressure resistance.

Description

technical field [0001] The invention relates to the field of heat insulation materials, in particular to a composite material with good heat insulation effect and a preparation method thereof. Background technique [0002] Heat insulation refers to the physical process in which the temperature change per unit space becomes smaller due to the change of the conduction medium when heat is transferred from a space with a higher temperature to a space with a lower temperature during the heat transfer process. It can also be achieved through dynamic technical means such as aerodynamics to achieve heat insulation. [0003] With the development of science and technology and economy, more and more occasions need to use materials with good heat insulation effect to block the heat transmission. The heat insulation material adopts a single heat insulation, and the heat insulation effect is limited, and the existing heat insulation materials are brittle to a certain extent, and the comp...
