Modified heat-insulation carbon fiber composite material and preparation method thereof

Abstract

The invention discloses a modified heat-insulation carbon fiber composite material and a preparation method thereof. The modified heat-insulation carbon fiber composite material comprises raw materials, pigments and additives, wherein the raw materials include silicon powder, crushed betel nut shells, water, a potassium hydroxide solution, phenol, concentrated sulfuric acid, a dioxane aqueous solution, polyvinyl alcohol and a formaldehyde solution; the pigments include coloring pigments; and the additives include a water repellent, an antioxidant, a preservative and a mildew preventive. In the invention, the modified heat-insulation carbon fiber composite material is a novel porous fibrous adsorption material, has larger specific surface area, higher pore volume, higher adsorption rate and stronger regeneration capacity due to the unique pore structure and form, and shows excellent performance in the aspect of heat insulation; and compared with a traditional heat insulation material, the composite material is relatively small in size and good in heat insulation effect in use, so that relatively large space in a house is prevented from being occupied in use, and the space utilization rate is improved.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a modified heat-insulating carbon fiber composite material and a preparation method thereof. Background technique [0002] With the development of the times, the demand for heat insulation materials in buildings is also increasing, and the performance requirements for heat insulation materials are getting higher and higher. The exterior walls, interior walls, and roofs of houses need to use heat insulation. Insulation materials, such as breeding sheds in farms, also need to use heat insulation materials. At present, traditional heat insulation materials are generally used in the market, including foam insulation materials, glass fiber and asbestos. [0003] However, firstly, the thermal conductivity of traditional thermal insulation materials is high, and the volume is too large when used, which occupies a large space inside the house and reduces the space utilization...

AI Technical Summary

Problems solved by technology

[0003] However, first of all, the thermal conductivity of traditional thermal insulation materials is relatively high, and the volume is relatively large when used, which occupies a large space inside the house and reduces the space utilization rate. Secondly, for dark and humid places in the room, After long-term use of traditional thermal insulation materials, the possibility of damp and mildew has increased. Finally, the traditional thermal insulation materials have a single color, and consumers cannot choose thermal insulation materials of different colors according to the actual situation. For example, consumers Use black thermal insulation material outdoors, black can absorb the heat in the sun and enhance the thermal insulation effect
