Insulation materials have traditionally been made from inorganic substances. However, in recent years, such materials have been restricted due to potential health risks. Therefore, it is extremely important to conduct research on organic-based insulation materials.
The objective of this study was to investigate the potential for recycling peanut shell waste by creating a new low-thermal insulation material through the incorporation of sunflower husks as a filler in a composite resin. Chemical composition of the organic fillers, including the content of cellulose, hemicellulose, lignin, proteins, and lipids, may affect the material's degradation, hardness, rigidity, and adhesion to the chosen polymers. For this reason, chemical properties such as moisture content, fat content, fiber content and ash content are the most important factors to be considered and were determined as 6.45%, 2 %, 61%, 6 %, respectively.
An insulating material was developed from sunflower husks, textile waste, and urea–formaldehyde resin. The prepared samples were wrapped in a special cardboard housing and their thermal and noise insulating properties were determined. As a result, resin composites filled with sunflower husks exhibited the best physical properties and demonstrated its potential as an environmentally friendly and inexpensive material.
