how to make wood adhesive using tree ssap

BACKGROUND OF THE STUDY The idea of this study is to make a wood adhesive by the use of natural ingredients, specifically Rubber tree sap, Soybean, & Star Apple leaves mix with grind dried leaves. For there is an urgent need to new environmentally friendly wood adhesives that is due to the new regulations and environmental concerns regarding the emissions of formaldehyde and its carcinogenic vapour, and due to the limited amounts of petroleum sources. Moreover, we want to enhance the adhesive performance that can be achieved by the mixture of our ingredients. Thus, this research revolves on reinforcing the protein of soybean with latex of rubber tree and the chemical component of star apple leaves. It is important to realize that protein adhesives are different from other adhesives in two major ways. First, in chemical terms, most adhesives, whether synthetic or bio-based, are polymers made from one or a few monomers, usually with similar functionality. However, proteins are made from more than 20 amino acid monomers with side chains containing a variety of functional groups. Second, morphologically, adhesives generally can be well described by understanding their primary and secondary structures. However, soy proteins also have tertiary and quaternary structures. Their polypeptide backbone not only influences the secondary structures of crystalline α-helix and ß-sheet regions (which are distinct protein structural configurations), but also influences the specific folding that forms the tertiary structures. Understanding how conditions alter these tertiary structures is an active research area for fields ranging from enzymatic activity to prion (proteinaceous infectious particle)-related diseases. The protein folding influences polypeptide agglomerates, which is the quaternary structure.
