Abstract

Adhesive is very important when it is used to produce a fiber/particle board. Natural adhesive is getting more important nowadays as the usage of synthetic adhesive is increasing nowadays and synthetic adhesive is giving harm to human and environment. Soy protein adhesive is one of the natural adhesives that are well known by people. The weak properties of soy protein adhesive such as its fire resistance, water resistance and adhesive strength limit the wide applications of it. In this project, the co-effect of both sodium sulfate and calcium carbonate with soy protein adhesive is being studied. The adding of sodium sulfate and calcium carbonate is believed to increase the properties of soy protein adhesive fiber board. Fiber treated with di-ammonium hydrogen phosphate is also believed to increase the fire resistance property of fiber board. In this project, oil palm fiber will be used to produce soy protein adhesive fiber board because of its average properties.
