Abstract

The synthesis of silica gel from rice husk ash has been carried out using the sol-gel method, which is mixed into paint as an additive for heat resistance. This research aims to determine the combination of adding SiO2 additive to wall paint as a heat-resistant coating material. The characterization methods used are FTIR, XRD, and SEM. The initial stage of this research involves the synthesis of silica gel from rice husk ash, which is then mixed into 10 mL of paint with varying silica additions of 0.1; 0.2; 0.3; 0.4; and 0.5 grams. After that, it is tested for heat absorption. Based on the FTIR results on silica, silanol (Si-OH) and siloxane (Si-O-Si) groups were observed, and the XRD results indicated that the silica structure produced was amorphous.

Abstract

Combination of Silica with Ni to become Ni/SiO2. This study aims to determine the combination of Ni/SiO2 additives to wall paint as a heat-resistant coating material. The characterization used is FTIR and XRD. The initial stage of this study involved the synthesis of nickel silica, after which it was mixed into 10 mL of paint with variations in the addition of nickel silica of 0.1; 0.2; 0.3; 0.4; and 0.5 grams. After that it was tested for heat absorption. Based on the FTIR results on silica, it shows silanol groups (Si-OH) and siloxane groups (Si-O-Si) and the XRD results show that the structure of the resulting silica is amorphous. variations in the mixture of these materials affect the specific heat of the coating. The more Ni/SiO2 that is mixed, the smaller the specific heat will be. This indicates that the coating does not absorb heat but reflects heat.
